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 difcult 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 protable 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 prot 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 ofce 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!
1
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-efcient 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 benet, 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.
7
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.
L2 Lock Mode (disables the jets buttons to prevent unauthorized use of the hot tub) ltration/heating
cycles and heater will continue to operation as programmed in this mode. The temperature display

4.10 2012+ CLEARRAY Facts
Our water purication 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 purication 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.

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
