1.0 Standard Troubleshooting Approach (S.T.A.)

1.1 Why a Standard Troubleshooting Approach?

Service prices are basically set by local industry and geographic region. Stiff competition in the service indus-

try has made it difcult to raise the price of a service contract; or charge more for time and materials than the competitive shop down the street. If your service business is to be protable you must control the overall cost

of service. The total cost of service is made up of many individual cost factors, but three in particular are more important than the rest combined:

1. Time of Repair - How long it takes to nd and x a problem.

2. Time Between Failures - How often you are called to repair any one particular hot tub? How many times

are you called back to x the same problem on the same hot tub?

3. Parts Usage - Except in rare circumstances, only one part fails. How many parts do you replace before you

nd the bad one?

This S.T.A. manual has been designed to help you control the overall cost of service by focusing on the three

important aspects of your job outlined above. The S.T.A. will help you x your customer’s hot tub quickly, x it

well, and use fewer parts.

1.2 How to Use the S.T.A.

The S.T.A. was developed by the Technical Support Department and is designed to be the communications link between you and your customers. If you call for help on any symptom covered in this book, you will be told to do what the S.T.A. recommends, therefore, you will save time by calling technical support after you have done what the S.T.A. tells you to do.

1.3 Professional Customer Service

Doing your job in a way that keeps cost of service low and prot margin high also creates customer satisfaction. That’s being a professional!

1.4 Before Leaving the Shop

Phone the customer(s), personally if possible, and ask what problem(s) should be corrected. This may not tell

you what work must be done or what part(s) must be replaced, but it will tell you what you must x after you

arrive.

1.5 Fixing the Hot Tub

Use the S.T.A. to see how the Technical Support Department would approach the customer’s complaint. Try to

x the problem following the S.T.A. Use your experience and other information to help you answer any “Whys”

or “Hows.” The S.T.A. is designed to keep unnecessary part replacement to a minimum. Least expensive, most

likely, and easily changed parts are always swapped rst. Some parts, like control panels and temperature

sensors do not require complete installation to be temporarily swapped out for testing purposes. You should carry such spares as “Tools.”

1.6 Before Calling Technical Support

Make sure you have followed the S.T.A. and lled out a “Troubleshooting Data Collection Form”

(refer to example on page 63). Have the S.T.A. manual and the Troubleshooting Data Worksheet near the telephone. Technical Support can help you best if these two things become the communications tools for the phone call.

1.7 Before Leaving the Customer

Even if you didn’t have to ll out a Troubleshooting Data Collection Form, please do so. If this is a warranty repair, the information will be needed when your ofce lls out the “Warranty reimbursement form.” In any case,

it will help you spot trouble before it happens. Pumps burn up if voltage at the hot tub is too low. Circuit breakers trip if heaters and motors draw too much current (Amps). Wires overheat and connections burn if wire size is too small or push-on connectors are loose. Call backs cause cost of service to increase!

Page 6

1.8 Satisfying the Customer

Most customers do not care what work you have done or what parts you have replaced, but they always care whether or not their problem goes away. When you are done, show them that their problem is gone. If they ask how you did it, take a few minutes to explain. Show them the bad part(s) and explain or show why it is bad.

• Develop the habit of examining the hot tub’s you service. Compliment customers on the

things they are doing right. Tell them how their care and attention can stop trouble before it starts.

• Mention if you noticed any adverse conditions, especially in hot tub’s under warranty or contract, that could

lead to failure. Can the customer correct the problem? Would they like you to correct it? Can you recommend someone? Would they like an estimate?

• Think of yourself and the customer as a “team” trying to keep the product up and running as cost-effective

and time-efcient as possible. That’s good for the customer, and it is good for your business.

2.0 Electro Static Discharge (E.S.D.)

2.1 E.S.D. - What is it? What does it do?

Static electricity is always being generated around us, even at those times of the year when we no longer get zapped after walking across a rug and touching something.

Like all state-of-the-art circuit boards, the hot tubs circuit board can be damaged by unnoticed static electricity. Damaged is the key word. Sometimes a board which has been subjected to E.S.D. will fail immediately upon being put back into service.

• If the hot tub runs only a few days, the customer thinks you provided poor service.

• If the hot tub runs only a few months, the customer thinks the circuit board is a low quality product.

• The customer loses use of the hot tub. You lose money because you must go back to make it right.

Jacuzzi loses its reputation for quality.

2.2 Avoiding E.S.D. Damage

We can’t prevent static charges from building up within our bodies as we go about our jobs, so we must do three things to protect circuit boards from getting zapped:

1. Never transport or ship circuit boards - Good boards or bad boards -

except in static protective bags.

2. Never remove the board from the static protective bag unless you are

ready to install it in the hot tub.

3. After removing the bad board from the hot tub, A) lay it on the ground,

B) remove the replacement board from the static protective bag, C) lay the replacement board on the ground, D) place the bad board in the bag from which you removed the replacement board, E) return bad board(s) in undamaged sealed static protective bags.

2.3 What About Wrist Straps and Special Mats?

The purpose of these devices is to keep the technician, the work surface, and the circuit board at the same electrical potential, and to drain into ground any static charges which might build up. Proper use of the wrist strap and special mat guarantees maximum protection against E.S.D. damage.

2.4 Must Wrist Straps and Mats be Used When Replacing A Circuit Board?

No, if you keep the spare board in the protective bag during transport and you observe a few simple techniques during replacement.

The possibility of E.S.D. damage to the circuit board during replacement will be minimal because of the hot tub’s design and the way you normally work on it. Touching the grounding lug or heater will drain all built-up static charges from your body much like a wrist strap would. Laying the bad board on the ground will tend to

keep it neutral. Touching a nger to the grounding lug or heater immediately before removing the good board

from the bag will drain any charges built up by the rustling of your clothes. Laying the good board on the ground after removing it from the bag will tend to keep it neutral. Another quick touch of the grounding lug or heater before picking up the bad board will again drain built up charges. Slipping the bad board into the protective bag will allow it to be transported safely. Another quick touch of the grounding lug or heater before picking up the good board will again drain any charges built up by the rustling of your clothes. In the process of installing the replacement board, you and the board will be grounded to the load box, grounding lug, or heater, draining off charges you may build up during installation.

4.0 Standard Programming Functions

4.1 Setting Filter Cycle Start Time (J200/ 2011-2013 J300/ JLX Collections)

Two methods for setting the lter cycle start time are possible:

1. Turn power on to the hot tub two minutes prior to the desired lter cycle start time, or

2. Press and hold both WARMER and COOLER buttons at the same time, then press the JETS 1

button once to reset the control panel and start the power-up sequence. During the power-up se-

quence, the factory default lter cycle (F1) and temperature setpoint 100°F (38°C) are automatically selected. To select another lter cycle at this time, refer to Section 4.2 below. The selected lter cycle will start approxi-

mately two minutes after the power-up sequence ends. Example: If you desire your rst lter cycle to begin at 10:00 AM, perform either of the above steps 1 or 2 at 9:58 AM. Filter cycle start time may vary slightly from

setpoint.

4.2 Filtration Options

The control system activates a programmable “standard” or “economy” ltration/heating cycle to remove larger debris missed by the circulation pump ltration system (when equipped). These cycles utilize pump 1 and the larger lter cartridge end to quickly clear “skim” the water of large debris and minimize their “bathtub ring” effect. Apart from their ltration benet, each mode also effects the op-

eration of your spa’s heater. Refer to Section 4.3 below for additional information.

A. F0-F3 Standard Skimming/Heating Modes (2011-2013 J300 Collection)

Standard ltration/heating modes are typically selected by customers that use their spa on a fre-

quent basis and desire a fully heated spa when lifting the cover. In these modes, the water temperature is regulated by the set temperature, the circulation pump, and heater which turns on as needed. After the programmed set temperature is reached, the heater turns off and the circulation

pump continues to operate for the remaining of the cycle to lter and clean your spa.

Note: In 2011-2012 the circulation pump had a default runtime of 24 hours. In 2013 the default time changed to 8 hours (except for the J-315 and J-325).

B. F4-F6 Economy Skimming/Heating Modes (2011-2013 J300 Collection)

Economy ltration/heating modes are typically selected by customers that use their spa on an infrequent

basis or to simply desire to minimize energy consumption levels. In these modes, the water temperature is

regulated by the set temperature, circulation pump, and heater only while a programmed lter cycle is running (unless in summer logic; refer to Section 5.4, page 14).

Note:

• Economy modes may consume less energy than standard modes above, in cold or freezing conditions.

• In 2011-2012 the circulation pump had a default runtime of 24 hours. In 2013 the default time changed to 8 hours (except for the J-315 and J-325).

C. F0-F3 Standard Skimming/Heating Modes (J-LX Collection)

Standard ltration/heating modes are typically selected by customers that use their spa on a frequent basis

and desire a fully heated spa when lifting the cover. In these modes, the water temperature is regulated by the set temperature. The circulation pump, and heater turn on as needed. After the programmed set temperature is reached, the heater turns off and the spa continues normal operations.

Note: The circulation pump also supplies heated water to the spa when the heater turns on. Any time the circulation pump runs outside of a programmed cycle, that run time will reduce the length of the next cycle, started in 2014.

D. F4-F6 Economy Skimming/Heating Modes (J-LX Collection)

Economy ltration/heating modes are typically selected by customers in warm climates where heat up

times are minimized due to higher ambient temperatures. In these modes, the water temperature is regulat-

ed by the set temperature. The circulation pump, and heater only while a programmed lter cycle is running (unless in summer logic; refer to Section 5.4, page 14).

Note: Economy modes may consume less energy than standard modes above, in cold or freezing conditions.

Page 12

E. F0-F3 Standard Skimming/Heating Modes (J200 Cellection; F0 Mode used on 2011-2012 circulation

pump models)

Standard ltration/heating modes are typically selected by customers that use their spa on a frequent basis

and desire a fully heated spa when lifting the cover. In these modes, the water temperature is regulated by the set temperature, and heater which turns on as needed. After the programmed set temperature is

reached, the heater turns off followed by the jets pump 1 unless a programmed ltration cycle is running.

Note: Standard modes may consume more energy than Economy models below in cold or freezing climates.

F. F4-F6 Economy Skimming/Heating Modes (J200 Cellection)

Economy ltration/heating modes are typically selected by customers in warm climates where heat up

times are minimized due to higher ambient temperatures. In these modes, the water temperature is regu-

lated by the set temperature, and heater only while a programmed lter cycle is running (unless in summer logic; refer to Section 5.4, page 14).

Note: Economy modes may consume less energy than standard modes above in cold or freezing conditions.

G. Lock Modes L1-L3

These modes are designed for use during spa service or to prevent unauthorized use.

Note: Economy modes may consume less energy than standard modes above in cold or freezing conditions.

4.3 Programming Filter Cycles (J-LX/ 2011-2013 J300 Collection)

To select a pre-programmed lter cycle or lock mode, press and hold both control panel WARMER

and COOLER buttons at the same time, then release. Then press either WARMER or COOLER

buttons to select either lter mode F0-L2. During the ltration heating cycle the jets pump1 low speed

and circulation pump will activate.

Standard Mode F0 5 minutes of ltration per day (one 5 minute “Blow-Out” cycle every 24 hours to purge all plumbing lines. F1 1 hour of ltration per day (one 30-minute cycle every 12 hours); this is the factory default setting. F2 1.5 hours of ltration per day (one 30-minute cycle every 8 hours). F3 2 hours of ltration per day (one 30-minute cycle every 6 hours).

Economy Mode F4 1 hour of ltration/heating per day (one 30-minute cycle every 12 hours). F5 1.5 hours of ltration/heating per day (one 30-minute cycle every 8 hours). F6 2 hours of ltration/heating per day (one 30-minute cycle every 6 hours).

Lock Mode L1 Lock Out (disables all hot tub functions to permit lter cleaning). Note: The spa should not be left in this lock mode for an extended period of time. Especially in colder climates

or when freezing conditions exist.

4.10 2012+ CLEARRAY Facts

Our water purication system will begin disinfecting your water instantly.

is exclusive technology utilizing natural ultraviolet technology to sanitize your water, disinfecting bacteria, viruses, and algae in portable hot tubs. The ultraviolet light otherwise known as UV-C or germicidal light inactivates the microorganisms by disrupting the DNA so that it cannot reproduce and is considered lifeless. The bal-

last is the power supply for the purication system; it has two LED indicator lights the green indicating incoming power ow and the red indicating the system is properly working. CLEARRAY is standard for all models.

Note:

• For JLX/2011-2013 J300 Models: The CLEARRAY System only runs when the circulation pump is running

and shuts off when either jets pump is manually activated during spa use. The system will remain off for 5 minutes after both jets pumps time out or are manually turned off, then resume operations if the circulation pump is programmed to run.

• For J200 Models: The CLEARRAY System only runs when the jets pump 1 is running.

System Specications are:

5.0 Additional Control Panel Functions

5.1 Setting Water Temperature and Overtemp Feature

1. Press WARMER or COOLER button once and release while the current water temperature is

displayed to view the current temperature setpoint, then;

2. Press WARMER or COOLER button within 3 seconds to increase or decrease set temperature setpoint in 1 degree increments as desired. Water temperature can set to any value within 65-

104°F (18-40°C);

3. After 3 seconds of keypad inactivity the LED display will return to actual water temperature and the new temperature setpoint will be maintained.

4. To access the overtemp feature that allows the spa to reach 106ºF (41ºC) follow the steps below:

A. Press and hold the WARMER button then;

B. Press and hold the JETS 1 button at the same time for 2 seconds. You will see the tempera-

ture rise to 106ºF (41ºC) on the LED display. To lower the temperature, press the COOLER button.

C. When the overtemp has been activated, the white decimal point after the last digit will ash on and off

every second as an indicator for being in the overtemp mode.

5.2 Selecting Jets Speed

• Press JETS 1 once for low speed; a second time for high speed; a third time to turn off.

• Press JETS 2 (2 Pump Models Only) once for high speed; a second time to turn off.

Note: Anytime a pump has been manually turned on by selecting either jet button, it will automatically turn off after approximately 20 minutes. If at this time you desire more jet operation, simply turn the jet pump back on.

5.3 Lock/Unlock Control Panel

The control panel temperature display ashes when Lock Mode is active. Lock Mode disables the

jets and underwater light to prevent unauthorized use of the hot tub or disables all hot tub functions

to permit lter cleaning.

5.4 Summer Logic (Models equipped with the Circulation Pump Option)

When water temperature in the hot tub rises to 2°F (1°C) above the temperature setpoint, the hot tub goes into “summer logic.” When this happens, the circulation pump automatically turns off to prevent heat addition from the pump that would eventually create an overheat condition. The circulation pump, main pump, CLEARRAY and aftermarket ozone (if applicable) will remain off until the water temperature cools to the set temperature, then reactivate as programmed. This setting

7.0 Troubleshooting Using The Control Panel

7.1 Control Panel Displays

Complete operating instructions for the control panel can be found in the owner’s manual. The hot tubs selfdiagnostic control system constantly monitors the hot tub for proper operation. When anything goes wrong, the control panel displays a message for the user which may result in a service call. Refer to Section 7.3 below for a listing of error messages and probable causes.

7.2 Control Panel Default Display

The control panel displays the following information during initial start-up:

1. Control panel displays current software microchip revision, then

2. Control panel displays “888” and all indicator LED’s are lit, permitting visual inspection of all

display segments and indicator lights for proper operation.

3. After the initial start-up sequence ends actual water temperature is displayed. If the water

temperature at this time is less than the factory default temperature setting of 100°F (38°C):

• J-LX and J-LXL Models: The low speed pump, circulation pump and heater will turn on

and run until the water temperature rises to the factory default temperature setting. Then the low speed pump and heater turn off. The circulation pump will continue to run for the remainder of the 8 hrs.

• 2011-2013 J300 and J200 (2011-2012 with Circulation Pump) Models: The circulation pump and heater

will turn on and run until the water temperature rises to the factory default temperature setting. Then the heater turns off and the circulation pump remains on for the remainder of the programmed cycle.

• J200 (2011+ without Circulation Pump) Models: The low speed pump and heater will turn on and oper-

ate until the water temperature rises to the factory default temperature setting, then both turn off.

Example sequence shown. Actual sequence can vary depending on model.

Approximately two minutes after initial start-up, the rst ltration cycle begins to operate. The ltration cycle can be modied any time after the start-up sequence ends. You will be able to select a pre-programmed lter cycle and reset your temperature setpoint at this time. Press either COOLER or WARMER button once at

this time to display the current temperature setpoint. You can change the setpoint by pressing either COOLER or WARMER button within 3 seconds. Each button press increases or decreases the temperature setpoint by one degree. Three seconds after the setpoint is set, the display defaults back to actual water temperature.

7.3 Control Panel Status and Error Messages

SN1 Nonfunctional Hi-limit Sensor (All Models)

Open or shorted hi-limit sensor. Heater is deactivated. Refer to test steps 1-2 below:

1. Turn off main breaker to hot tub. Refer to appendix, page 56, for expected hi-limit sensor

resistance/water temperature values.

2. Remove hi-limit sensor connector from circuit board test point 21. Refer to pages 50-53 for your circuit

board conguration. Set ohmmeter to 100 kΩ - 200 kΩ range, then measure resistance across hi-limit sensor wires (refer to page 56). If sensor resistance tests OK (± 200 Ω), check sensor connections. If con-

nections are OK, replace circuit board. If sensor resistance is incorrect, replace hi-limit sensor.

SN2 Nonfunctional Temperature Sensor (All Models)

Open or shorted temperature sensor. Heater is deactivated. Refer to test steps 1-2 below:

1. Turn off main breaker to hot tub. Refer to appendix, page 56, for expected hi-limit sensor

resistance/water temperature values.

2. Remove temperature sensor connector from circuit board test point 21. Refer to pages

50-53 for your circuit board conguration. Set ohmmeter to 100 kΩ - 200 kΩ range, then

measure resistance across temperature sensor wires (refer to page 56). If sensor resistance tests OK

(± 200 Ω), check sensor connections. If connections are OK, replace circuit board. If sensor resistance is

incorrect, replace temperature sensor.

Page 24

FL1 & FL2 Water Flow Problem (All Models)

• FL1: ow or pressure switch not closed when circulation pump is running. Heater is deacti-

vated. Proper water ow is inhibited or ow/pressure switch may be obstructed, misaligned,

or defective. Refer to troubleshooting steps 1-5 below:

1. Remove lter and allow air to bleed out of cartridge. Check lter for trapped air.

2. Check for proper water level.

3. Check for clogged lter cartridge.

4. Check for sticking or damaged oating skimmer.

5. If problem persists, refer to Section 7.4 (page 21) for ow/pressure switch testing instructions.

• FL2: ow switch or pressure switch closed when pump is not running. Heater is deactivated

and pump may or may not turn on. Flow/pressure switch is defective. Refer to Section 7.4 (page 21) for switch testing instructions.

COL Cool Condition (All Models)

If the water temperature drops 20°F (11°C) below the set temperature, the low speed pump and heater will activate to raise the water temperature within 15°F (8°C) of the set temperature. No

corrective action is necessary. This condition is common during water changes and/or rst time ll

ups.

ICE Freeze Condition (All Models)

A potential water freeze condition of 55°F (13°C) has been detected. No action is required. The low speed pump and heater will activate and raise water temperature to approximately 65°F (18°C), canceling the “ICE” error message. After the error message is canceled, the low speed pump will turn off (circulation pump models only) and the heater will remain on until the set temperature is reached.

OH Overheat Condition (All Models)

Water temperature is above acceptable limits. DO NOT ENTER HOT TUB WATER! Water temperature has reached 116°F (47°C) and the low speed pump has activated to circulate water through the heater to cool it down for approximately 6 minutes. Refer to test steps 1-4 below:

1. Verify actual water temperature with an accurate thermometer. If actual water temperature is

less than 110°F (44°C), proceed to steps 2-4.

2. Turn off main breaker to hot tub. Refer to appendix page 56 for expected hi-limit/temperature sensor

resistance/water temperature values.

3. Remove hi-limit sensor connector from circuit board points 22. Verify that the heater is not excessively hot.

Refer to pages 50-53 for your circuit board conguration. Set ohmmeter to 100-200 kΩ range, then measure resistance across sensor wires (refer to page 56). If resistance tests OK (± 200Ω), check wiring

harness connections. If wiring harness connections test OK, replace circuit board. If sensor resistance is incorrect, replace hi-limit sensor.

4. Set ohmmeter to 100-200 kΩ range, then measure resistance across temperature sensor wires (refer to

page 56). If resistance tests OK (± 200Ω), replace circuit board. If temperature sensor resistance is

incorrect, replace sensor.

Page 25

“- - -” Watchdog (All Models)

Water temperature has reached 118°F (48°C). DO NOT ENTER HOT TUB WATER! The entire system is disabled. Refer to test steps 1-4 below:

1. Check hi-limit and temperature sensor resistance values. Both sensors should measure

close in resistance to each other (e.g. one may be defective and way out of range). Refer to appendix page 56 for expected hi-limit/temperature sensor resistance/water temperature values. If either sensor is faulty, replace it and recheck system. If problem persists, proceed to steps 2.

2. Plug in new control panel. If problem persists, proceed to step 3. If problem corrects, replace panel.

3. Check voltage at transformer secondary. Refer to Section A29, page 58 for transformer testing instruc-

tions. If voltage is bad, replace transformer. If voltage is good, perform step 4.

4. Check circuit board transformer connections. If connections are loose or oxidized, repair connections and

retest system. If problem persists, replace circuit board.

7.4 Testing Flow/Pressure Switch

Testing The Flow Switch

•All J-LX Models

•All 2011-2013 J300 Models

•All J200 Models (with the Circulation Pump Option)

A. Verify ow switch directional arrow is pointing in the direction of ow away

from the heater output. If switch orientation is incorrect, loosen or tighten

switch no more than 1/2 turn, being careful not to bottom out switch in tting. The switch’s ow arrow must be parallel to tee tting as shown (Fig. 1). Test

system operation. If condition corrects, skip steps B-C.

B. Remove switch from tting making note of the number of turns (revolutions)

it takes to do so. Visually inspect switch for debris interference or damage. If debris is present, remove debris, then install switch with the same number of turns as originally installed. Test system. If switch is damaged, replace switch and retest system. If condition corrects, skip step C.

C. Test switch operation with an ohmmeter (set to 1000-

2000 Ω range) for continuity across switch terminals. Measure resistance

across switch terminals for innite resistance with the magnet arm not touching the switch body (Fig. 2), and for continuity (0 Ω) with the magnet arm touching the switch body (Fig. 2). If ow switch tests OK, check switch

wiring harness. If wiring harness tests OK, replace circuit board.

D. Verify that low ow is not preventing the ow switch from closing.

A. Remove switch. Visually inspect switch for debris blockage. If debris is present, remove debris, install

switch and test system. If condition corrects, skip step B.

B. Disconnect wires from switch terminals. Set ohmmeter to 1000-2000 Ω range. Measure resistance across

switch terminals for innite resistance with pump off (Fig. 3). If continuity (0 Ω) is measured with pump off, the switch is defective, replace switch. If switch measures innite Ω (no continuity) with pump off, switch is OK. Turn on main pump and measure across switch terminals for continuity (0 Ω). If continuity (0 Ω) is

measured, switch is OK. Check wiring harness. If wiring harness tests OK, replace circuit board.

If the switch tests ok in the steps above, check the wiring harness connections between switch and circuit board. Scrape the switch’s contact pin surfaces to remove any oxidation or conformal coating.

8.2 Intermittent Heating

As with all intermittent problems, routine measurements and display panel error messages are not trustworthy. The following procedure will eliminate the most probable causes.

It is important to explain to the customer how difcult intermittent problems are to locate. You will be doing a series of things to eliminate the problem. Ask the customer to be patient and please cooperate by calling you back to inform you of the hot tubs status until the problem is corrected. It might be a good idea to review this S.T.A. with the customer. It may help he or she understand why it might take several service calls to effect a repair.

Suspects: circuit board, temperature sensor, control panel, wiring connections, and partial water ow obstructions.

Diagnostic Tools

Voltmeter, Ohmmeter

Suggested Spare Parts

Heater element, circuit board, temperature sensors, pressure switch, control panel

Standard Troubleshooting Approach

1. Check crimped wire connections to heater element. If burned, replace heater element wires. Verify heater element connections are good on circuit board. Check heater resistance, see current chart on page 45 for expected heater resistance values.

2. Check connections labeled “heater out” on circuit board (test points 12 and 13). Refer to pages 50-53 for your circuit board. If possible, clean and renew connections. If relay is physically burned at connections, replace circuit board.

3. Check ow switch or pressure switch for proper and consistent mechanical operation. Observe mechanical

action of switch. Refer to page 21 for ow switch testing procedure.

4. Clean connections where panel plugs into board.

5. If all above items check out, ask the customer if the SN2 error has ever displayed. If the SN2 error message has displayed, replace temperature sensor.

6. Tell the customer what you have done, that you are not sure the problem has been xed, and that you want

to be called immediately if the problem returns. Explain what you will do if the problem returns. Check back with the customer in a few days if you haven’t been contacted.

7. If the customer calls back, call Technical Support.

Note: J-LX/2011-2013 J300/J200 (with circ pump) Models use a “magnetic reed switch”

type ow switch that can remain closed from debris interference. Removal of the ow

switch for cleaning and inspection will correct most problems. Record the number of turns

it takes to remove the switch from the tting. After cleaning, use the same number of

turns to reinstall the switch. DO NOT thread the switch farther than originally installed, or

the paddle may stick on the bottom of the tting. Also, make sure ow arrow is pointing in direction of ow away from heater output.

8.3 Nothing Works

Things to remember: when a system fails, there is probably one, and only one problem. Verify power to the hot tub by observing the control panels LED display. The control panel will usually display something as long as there is power to the hot tub. Check for error messages. Displayed error messages usually indicate the problem.

Diagnostic Tools: Voltmeter

Suggested Spare Parts: Fuses, control panel, circuit board Nothing Works (Panel Indicators lit)

1. Plug in spare control panel. If it works, change panel.

2. Remove power from hot tub. Check connections on sensor harness and verify proper resistance of temperature and hi-limit sensors (page 57). Replace defective temperature or hi-limit sensor then test system.

3. Check transformer. See Section A24, page 58.

4 . Still no operation? Replace circuit board.

Page 32

Nothing Works (Panel Dead)

1. All Models - Check for proper power to the hot tub on the main TB1 terminal block (page 43) as follows:

• 120V Convertible North American Models: 120 VAC ±10% (3-wire).

• 240V North American Models: 240 VAC ± 10%.

2. Check for power at transformer secondary. Refer to appendix page 58. If power exists on transformer secondary, plug in spare control panel. Still nothing? Replace board.

3. If no power exists at transformer secondary, check for voltage at transformer primary. Refer to appendix page 58. If voltage exists on the primary but is missing on the secondary, replace transformer.

4. No power at the transformer primary indicates either an open 1.25 Amp fuse, 20/30 Amp main fuse, or a loose or disconnected wire. If voltage exists on the primary but is missing on the secondary, replace trans-

former. See Section A5 (page 48) for specic fuse details.

8.4 Hot Tub Doesn’t Come On for Filter Cycle

Turn power to hot tub off and on to restart lter cycle program. Does lter cycle start approximately two minutes

after power is applied?

• If yes: the hot tub is functioning properly. Refer to Sections 4.3-4.7 (page 7) for lter cycle setup details. Take time to explain lter cycle selection and operation to your customer. Make sure your customer understands lter cycles are selectable, not programmable.

• If no: Select appropriate lter cycle mode within two minutes after applying power. Refer to Sections 4.3-

4.7 (page 7). If lter cycle starts approximately two minutes after setting, no corrective action is required. If lter cycle does not start two minutes after setting, replace circuit board.

8.5 House Breaker Trips

The hot tubs current draw will vary depending on how the circuit board is jumpered. Jumper options determine whether multiple functions can operate together.

If the house breaker trips, check the hot tubs current draw. If jumpers are properly set and current draw is within expected limits, the house breaker or wiring is defective and must be repaired/replaced. The hot tubs current draw at the breaker represents the sum of all enabled devices. Refer to appendix page 46.

If the hot tub’s current draw is high, individual device current measurements must be made to determine which device is pulling excessive current. Refer to appendix page 46. Repair or replace the device which is drawing excessive current.

If the GFCI trips, try removing the heater, pump, ozonator (if installed), stereo power supply and circulation

pump or pump 2 wires from the circuit board one at a time to nd which device may be causing the GFCI to

trip. For chronic GFCI tripping, call Technical Support.

North American 60Hz Installations: As of January 1, 1994 the National Electric Code (NEC) requires a Ground Fault Circuit Interrupter on all hot tub installations in the U.S. A GFCI must be wired correctly or it will trip. Make sure the electrician has wired the GFCI according to the diagram on pages 54.

8.13 Troubleshooting A Thermal Pump Cutout

mmm...

1. Verify voltage to hot tub is 240 VAC ±10% (or 120 VAC ±10% for convertible models). An

insufcient voltage supply can cause the motor to pull too much current and overheat. The

situation must be corrected.

2. Check voltage to hot tub.

3. If voltage is OK, examine the environment in which the hot tub is installed. Hot sun, hot weather, and lack of breeze can cause heat build up in the equipment bay in addition to the normal heat produced by the pump. This can raise the temperature high enough to cause the pumps thermal cutout to trip. There are two possible solutions to thermal pump cutout problems which are not due to low line voltage. One is to change the lter cycle period so that it does not coincide with the hottest time of day and peak power consumption hours. Another is to ventilate the equipment bay. Call technical support for advice on this matter.

4. If there seems to be no overheating problem yet the motor keeps cutting out, the motor’s thermal switch may be bad. In this case the pump should be replaced.

8.14 Pump 1 Hums and Will Not Start

If the pump impeller is not “frozen”, this condition usually indicates a bad start capacitor. This component is inside the pump motor housing.

Diagnostic Tools: Voltmeter

Suggested Spare Parts: Pump, Capacitor, Circuit Board

Standard Troubleshooting Approach

Press JETS 1 button. Check voltage at the following circuit board test points 5 and 6.

North American 60 Hz Models:

All models (except J-315/J-325/J-210): 240 VAC ±10% J-315/J-325/J-210: 120 VAC ±10%

Export 50 Hz Models:

All models; 230 VAC ±10%

All Models

If there is no voltage present at the recommended test points, replace circuit board. If voltage is present, the pump needs to be repaired or replaced. Try replacing the pump’s start capacitor. If the pump still doesn’t work, replace pump.

If pump 1 runs in low speed but hums in high speed, make sure circuit board is not sending voltage to both pump windings at the same time. Disconnect pump wires from the circuit board before performing this test. Test for voltage at test points 5 and 6. When voltage exists at test points 5 and 6 there should be no voltage at test points 5 and 7. Conversely, when voltage exists at test points 5 and 7, there should be no voltage at test points 5 and 6. If voltage is present across both sets of test points at the same time, replace circuit board.

Refer to pages 50-53 for your specic circuit board layout.

A1 Checking Voltage to Hot Tub

Correct supply voltage wiring to the hot tub is essential for safe/proper operation. The rst step in troubleshooting a new installation should be to take voltage readings at the terminal block TB1. Do not trust wire colors. Electricians make mistakes and electrons are color-blind. A low line voltage or incorrectly wired hot tub will result in either of the following symptoms: A) Strange or intermittent symptoms, B) Displays with indications that simply cannot be correct

Many of the most perplexing problems in the past have been wiring errors and voltage drop problems. Human

safety depends on proper hot tub grounding. It is essential that the voltage readings described below are as indicated. The ground connection must be heavy duty wiring.

• J-210, 2011-2013 J-315, 2011-2013 J-325 North American 60 Hz are convertible for either 120 VAC 3-wire

operation or 240 VAC 4-wire operation. The 4-wire power conguration powers the heater with 240 VAC for

increased performance while powering all other components with 120 VAC.

• All other models are North American 60 Hz are exclusively powered by 240 VAC.

• All Models Export 50 Hz are exclusively powered by 230 VAC ±10%, see Figure C below.

Verify All Convertible Models Power Connections as Follows:

North American Models (120 VAC/60 Hz, Fig. A)

• Hot to Neutral: Measure across test points 1 and 2 with voltmeter for 120 VAC.

• Hot to Ground Test: Measure across test points 2 to 23 for 120 VAC.

North American Models (240 VAC/60 Hz, Fig. B)

• Hot to Neutral: Measure across test points 1 and 2 with voltmeter for 120 VAC; then across test points 1

and 24 for 120 VAC.

• Hot to Ground: Measure across test points 2 and 23 for 120 VAC; then across test points 24 and 23 for 120

VAC.

• Hot to Hot: Measure across test points 2 and 24 for 240 VAC.

A3 Checking Voltages to Devices

Device voltages are often measured at the circuit board to determine whether the board or device is bad. If the circuit board delivers voltage when device operation is called, the circuit board is probably good and the problem lies with the device or the wiring to the device. The following voltage chart shows operating voltages for all major hot tub components. Voltage is considered good if within ±10% of the listed value. Refer to appendix

pages 50-53 for your specic circuit boards test point locations.

A4 Testing Flow/Pressure Switch

When the “FL1 or FL2” message appears, it means the ow switch or pressure contacts have failed to close when the pump was turned on, or failed to open when the

pump was turned off. This could be caused by an excessively dirty lter, an obstruction in the ow path or by a bad switch. The rst thing to look for is an excessively dirty lter or an obvious obstruc-

tion, remembering (while not likely) that it is possible for a small object to work its way into the plumbing where

it will not be obvious. After verifying no obvious blockage exists, the ow or pressure switch can be tested.

Refer to page 21 for switch testing instructions.

A5 About Fuses

When current passes through a conductor the conductor heats up. If the conductor is a heavy piece of wire or

a strip of metal, it will pass large currents and generate very little heat. If a wire is ne, or a strip of metal is thin, it will heat up at lower current levels. Fuses rely on this principle to protect circuits from massive current ows

by simply melting if their current rating is exceeded. By selecting different alloys for the fuse element, fuses can be made to have their current rating exceeded for a short period of time. Such slow-blow fuses are excellent for protecting motor circuits where start-up currents (surge currents) are higher than running currents.

For 2014+ J300s see the 2014 J300 S.T.A.

Testing Fuses

A good fuse should read continuity (0 Ω); a blown fuse will read no continuity (innite ohms). See Figures 6

and 7 for testing methods.

CAUTION: Make sure replacement fuses are exactly those listed above. Never test a fuse for continuity while installed in the fuse holder.

A6 The Watchdog “- - -”

Three horizontal dashes with no other control panel indicators illuminated is a result of the watchdog circuitry detecting a potential destructive condition within the hot tub.

There are many conditions that can cause a watchdog error message. Except for a runaway heat condition, most are caused by a faulty circuit board, bad hi-limit sensor, or temperature sensor. On rare

occasions a control panel or a bad transformer will cause Watchdog. Conrm this by using a test panel and

testing transformer connections on the circuit board, refer to appendix page 58.

1. Turn power to hot tub off. Verify proper resistance of hi-limit and temperature sensor (page 56). Replace defective temperature or hi-limit sensor then retest system. If watchdog error goes away, skip steps 2-4.

2. If the heater is not overly hot to touch and the watchdog displays an immediate dashed line error, the circuit board is probably bad. Check transformer primary and secondary voltages (page 58) before changing the circuit board.

3. See if the temperature in the heater has reached 118°F (48°C). If the heater got too hot, check for ow

restrictions or a sticking weir gate and correct the problem.

4. If you cannot produce the watchdog error and the hi-limit and temperature sensors check out OK, tell the customer to call you if watchdog display reappears.

A7 Understanding Sanitizers

A. CLEARRAY

Our water purication system will begin disinfecting your water instantly.

• As the water is ltered, it passes through the CLEARRAY unit, and is exposed to UV light that sanitizes the water.

• The combination of the CLEARRAY system and a residual sanitizer work in conjuction to keep your water clear and clean.

B. Ozone Oxygen is an element, and like other gaseous elements, normally exists as a pair of atoms bonded together to make a whole molecule. Chemists therefore use the symbol O

oxygen atoms.

CLEARRAY Water Purication System

to speak of “oxygen molecules” rather than

In the presence of an electric discharge like lightning, three molecules of O

can combine to form O

known

as ozone. While oxygen has no smell, ozone has a very pronounced smell in large concentrations. In small quantities, it causes the pleasant “fresh air” smell that laundry has when dried on a outdoor clothesline. Some clothing dryer manufacturers have installed an ultraviolet lamp inside their machines to give clothes that “freshas-all-outdoors” smell.

The technician must understand three things about ozone:

1. Ozone (O

) breaks down quickly into plain oxygen (O2).

2. Ozone kills germs.

3. Ozone is a strong oxidizer.

Because ozone breaks down quickly into oxygen (O

), a residual sanitizer must be used. There are two

choices, chlorine or bromine. While chlorine is oxidized by ozone just as quickly as bromine, residual bromine compounds are a much better disinfectant than residual chlorine compounds. Hence ozone and bromine team up much better to do the overall job than ozone and chlorine.

A8 Understanding pH

Keeping hot tub water clean and clear involves a very complex set of chemical reactions. Most importantly,

the hot tub must be sanitized. Bacteria, algae, and other single-cell life forms that may nd their way into the

hot tub must be killed. Three chemical elements, chlorine, bromine, and ozone are all good sanitizing agents. When any of these elements come into contact with bacteria or algae, these single-cell organisms die. Therefore, to keep the water germ free, we must simply keep a residual of the sanitizing agent in the water.

Making germs dead is only half the objective, however. The dead cells of the bacteria and algae we have killed, and the organic “stuff” (dandruff, perspiration, dead skin cells, etc.) that our bodies deposit in the hot tub, will make the water cloudy and uninviting as they decompose. These microscopic contaminants must be “burned out” or oxidized. These oxidation reactions occur simultaneously with reactions known as reduction reactions. The balance of these chemical reactions is quite critical and can occur properly only if pH levels are maintained from 7.2 to 7.8 pH (Ideal 7.4 to 7.6). If the pH is out of range, the sanitizing agent itself will be oxidized or reduced and in effect be “used up” before it has a chance to do it’s job.

pH is critical for maximum disinfection, sanitizing, and cleaning results with the least amount of chemical addition. Make sure your customer understands the importance of regular water test intervals and the proper use of chemicals. Both are necessary to ensure maximum water quality and to maintain a healthy and fun hot tub environment.

Black to White 120 VAC* Yellow to Yellow 12-14 VAC*

*Special instructions for all 120 VAC/240 VAC convertible power models.

120 VAC Power Conguration: Convertible models include a factory installed 10 foot GFCI cord rated at 15A/120 VAC. To use cord the hot tub must be installed within 10 feet of a dedicated, grounded type electrical outlet. Do not use an extension cord of any type! If the hot tub is more than 10 feet from an outlet, it must be hard wired to a single pole 15 amp GFCI breaker. Refer to pages

50-53 for specic circuit board congurations.

240 VAC Power Conguration: Convertible models can be hard wired for 4-wire 120 VAC/240

VAC power. This conguration powers the heater with 240 VAC while powering both pumps and

ozone with 120 VAC. An external 30 or 40 amp dual pole GFCI breaker is required. Refer to pages

50-53 for specic circuit board congurations.
