F232059

Safety

Safe Operating Environment

Safe operation requires an appropriate operating environment for both the operator and the machine. If questions regarding safety arise, contact the factory immediately.

Environmental Conditions

● Ambient Temperature. Water in the machine will

freeze at temperatures of 32°F (0°C) or below. Temperatures above 120°F (50°C) will result in

more frequent motor overheating and, in some cases, malfunction or premature damage to solid state devices that are used in some models. Special cooling devices may be necessary.

Water pressure switches are affected by increases and decreases in temperature. Every 25°F (10°C) change in temperature will have a 1% effect on the water level.

● Humidity. Relative humidity above 90% may

cause the machine’s electronics or motors to malfunction or may trip the ground fault interrupter. Corrosion problems may occur on some metal components in the machine.

If the relative humidity is below 30%, belts and rubber hoses may eventually develop dry rot. This condition can result in hose leaks, which may cause safety hazards external to the machine in conjunction with adjacent electrical equipment.

● Radio Frequency Emissions. A filter is available

for machines in installations where floor space is shared with equipment sensitive to radio frequency emissions.

● Elevation. If the machine is to be operated at

elevations of over 3280 ft. (1000 m) above sea level, pay special attention to water levels and electronic settings (particularly temperature) or desired results may not be achieved.

● Chemicals. Keep stainless steel surfaces free of

chemical residues.

DANGER

Do not place volatile or flammable fluids in any machine. Do not clean the machine with volatile or flammable fluids such as acetone, lacquer thinners, enamel reducers, carbon tetrachloride, gasoline, benzene, naptha, etc. Doing so could result in serious personal injury and/or damage to the machine.

SW002

● Water Damage. Do not spray the machine with

water. Short circuiting and serious damage may result. Repair immediately all seepage due to worn or damaged gaskets, etc.

● Ventilation. The need for make-up air openings

for laundry room accessories such as dryers, ironers, and water heaters must be evaluated periodically. Louvers, screens, or other separating devices may reduce the available air opening significantly.

F232059

Safety

Replace all panels that are removed to perform service and maintenance procedures. Do not operate the machine with missing guards or with broken or missing parts. Do not bypass any safety devices.

SW019

CAUTION

Machine Location

● Foundation. The concrete floor must be of

sufficient strength and thickness to handle the floor loads generated by the high extract speeds of the machine.

● Service/Maintenance Space. Provide sufficient

space to allow comfortable performance of service procedures and routine preventive maintenance.

This is especially important in connection with machines equipped with an AC inverter drive.

Consult installation instructions for specific details.

Input and Output Services

● Water Pressure. Best performance will be

realized if water is provided at a pressure of 30-85 psi (2.0-5.7 bar). Although the machine will function properly at lower pressure, increased fill times will occur. Water pressure higher than 100 psi (6.7 bar) may result in damage to machine plumbing. Component failure(s) and personal injury could result.

● Steam Heat (Optional) Pressure. Best

performance will be realized if steam is provided at a pressure of 30-80 psi (2.0-5.4 bar). Steam pressure higher than 125 psi (8.5 bar) may result in damage to steam components and may cause personal injury.

● Compressed Air. For machines requiring

compressed air service, best performance will be realized if air is provided at a pressure of 80-100 psi (5.4-6.7 bar).

● Drainage System. Provide drain lines or troughs

large enough to accommodate the total number of gallons that could be dumped if all machines on the site drained at the same time from the highest attainable level. If troughs are used, they should be covered to support light foot traffic.

● Pow er. For personal safety and for proper

operation, the machine must be grounded in accordance with state and local codes. The ground connection must be to a proven earth ground, not to conduit or water pipes. Do not use fuses in place of the circuit breaker. An easyaccess cutoff switch should also be provided.

WARNING

Ensure that a ground wire from a proven earth ground is connected to the ground lug near the input power block on this machine. Without proper grounding, personal injury from electric shock could occur and machine malfunctions may be evident.

SW008

Always disconnect power and water supplies before a service technician performs any service procedure. Where applicable, steam and/or compressed air supplies should also be disconnected before service is performed.

For machines equipped with optional steam heat, install piping in accordance with approved commercial steam practices. Failure to install the supplied steam filter may void the warranty.

F232059

Safety

AC Inverter Drive

Machines equipped with the AC inverter drive require special attention with regard to the operating environment.

● An especially dusty or linty environment will

require more frequent cleaning of the AC inverter drive cooling fan filter(s) and of the AC inverter drive itself.

● Power line fluctuations from sources such as

uninterruptible power supplies (UPS) can adversely affect machines equipped with the AC inverter drive. Proper suppression devices should be utilized on the incoming power to the machine to avoid problems.

● A clean power supply free from voltage spikes

and surges is absolutely essential for machines equipped with the AC inverter drive. Nonlinear inconsistencies (peaks and valleys) in the power supply can cause the AC inverter drive to generate nuisance errors.

● If voltage is above 240 Volt for 200 Volt

installation, ask the power company to correct. As an alternative, a step-down transformer kit is available from the distributor. If voltage is above 480 Volt for 400 Volt installation, a buckboost transformer is required.

Misuse

Never use this machine for any purpose other than washing fabric.

● Never wash petroleum-soaked rags in the

machine. This could result in an explosion.

● Never wash machine parts or automotive parts in

the machine. This could result in serious damage to the basket.

● Never allow children to play on or around this

machine. Death or serious injury can result if children become trapped in the machine. Do not leave children unattended while the machine door is open. These cautions apply to animals as well.

● Sufficient space to perform service procedures

and routine preventive maintenance is especially important for machines equipped with the AC inverter drive.

Operation

Theory of Operation

The design of the washer-extractor emphasizes performance reliability and long service life. The cylinder, shell, and main body panels are fabricated of stainless steel.

Electrical controls for the washer-extractor are housed in separate enclosures. The front control module houses the WE-6 microcomputer, the fuse/relay board together with its interface board, water level switches, a motor thermal overload reset switch, and other control components. The rear control module houses the AC inverter drive and its components.

All variable-speed freestanding machines use the AC inverter drive control, which provides programmable motor speeds using a single motor. The AC drive interface board converts motor logic from the WE-6 microcomputer to the correct signals for the AC inverter drive. In addition, all logic inputs to the computer are routed through this board.

The cylinder is supported by roller bearings housed inside a trunnion.

The cylinder is constructed with four lifters or ribs that lift the laundry from the bath solution when the cylinder rotates at slow speed and then allow the laundry to tumble back into the bath. This mechanical action accomplishes the washing function. The cylinder is perforated, allowing the water to drain from within during the wash and extract steps.

Water enters the machine through electromechanical water valves controlled by the microcomputer. The microcomputer also controls the drain and door lock. In addition, it selects the water levels according to the programmed cycle. Vacuum breakers are installed in the water-inlet plumbing to prevent backflow of water.

A door-lock system prevents opening of the stainless steel door when a cycle is in progress. It also prevents operation of the washer-extractor when the door is open.

The doorbox contains the Hall-effect door-locked and door-closed sensors and the door-unlock solenoid.

The supply dispenser is located on the left side of the front of the washer-extractor. The dispenser has five supply compartments, numbered 1 to 5 from left to right. The compartments hold supply cups that are used for either liquid or dry supplies. A nozzle flushes supplies from the cups with water for the time programmed in the cycle.

Liquid supplies can be injected directly into the cups by a customer-supplied external chemical supply system. Five hose barbs on the rear of the washerextractor facilitate connection to an external supply system.

Emergency Stop Button

A red emergency stop button is located on the upper right-hand corner of the control panel. Push the button in to stop the washer-extractor. Turn button to the left and pull out to reset.

Wet Clean Features

The washer-extractor is equipped with the following wet clean capable features: One-half wash speed allows gentle mechanical action during wash. Eight supply signals provide not only normal laundering signals to dispense detergents, bleaches, softeners, sours, etc., but also chemicals unique to wet clean processing.

Motorized drain valves hold water in the machine during the wash, soak, and rinse steps. The drain valve is normally open, which means that it closes only when power is applied, thus allowing the machine to drain in the event of a power failure.

F232059

Operation

Wet Clean Capabilities

Differences in WE-6 prompt (setup) options

The WE-6 software provides the usual setup options:

● Degrees F or C

● One or Two drain

● Advance or No Advance

● Manual or No Manual

● Balance setting

In addition, the software provides a new selection: Wet Clean/No Wet Clean. The wet clean/no wet clean option enables or disables wet clean functions. In summary then, the prompt (setup) options are now as follows:

● CEN/FAR

● 1DRAIN/2DRAIN

● ADV/NO ADV

● MANUAL/NO MAN

● WET CL/NO WCL

● BAL SW, BAL 1, BAL 2, BAL 3

Wet Clean Functions

Wet clean functions include a reduced wash speed capability and a recirculation pump capability. These functions are enabled by the WET CL/NO WCL prompt selection. Other wet clean features are permanently enabled, and can be used for other applications as well. In particular, extra supply capability (up to eight supplies, in two banks of four supplies), and additional agitation actions as outlined below.

Agitations:

● Wash 1 – normal: 18 seconds forward / three

seconds off / 18 seconds reverse / three seconds off; repeat

● Wash 2 – gentle: three seconds forward /

27 seconds off / three seconds reverse / 27 seconds off; repeat

● Wash 3 – no rotation

● Wash 4 – ten seconds forward / 20 seconds off /

ten seconds reverse / 20 seconds off; repeat

● Wash 5 – uses most recent agitation; defaults to

Wash 1 agitation

● Wash 6 – super gentle: four seconds forward /

56 seconds off / four seconds reverse / 56 seconds off; repeat

● Wash 7 – no rotation; drain 1 (sewer drain) open;

no attempt to refill to level

F232059

Operation

Using the auxiliary 1 (A1) and auxiliary 2 (A2) outputs for wet cleaning

The A1 and A2 outputs (so labeled on the solid state WE-6 output PC board) can be made to operate as timed outputs, or to remain on until a drain step.

Reduced wash speed

Normally, the A1 output would govern optional reduced wash speed. This means that if the WE-6 is prompted for “WET CL”, and then an auxiliary 1 “A1” step is programmed for any amount of time (one second is a good choice for time in the event of controlling reduced wash speed), the A1 output will remain on until a drain step, or until Stop routine. Thereby the reduced wash speed remains in effect as long as A1 remains on.

For example, with “WET CL” prompt selected, a Wash 1 agitation is wanted, but at reduced wash speed. Program auxiliary 1 step for one second, then program a Wash 1 step. The A1 output will remain on during the Wash 1 step, selecting reduced wash speed during the Wash 1 step. Upon reaching a drain step, or upon entering the Stop routine, the WE-6 will operate the machine at reduced wash speed (PROVIDED the machine is equipped with the necessary hardware for controlling reduced wash speed).

Control of an optional recirculation pump

The A2 output will also remain on until a drain or the Stop routine if the WE-6 prompt is “WET CL” and if “1DRAIN” is selected. This would allow control of an optional recirculation pump by permitting the pump to continue operating during a wash step. For this control, program an auxiliary 2 “A2” step for one second or other suitable time, and the output would remain on until a drain step or until the Stop routine. The auxiliary 2 step would also go off upon entering a Wash 7 step.

Note that “2DRAIN” prompt will OVERRIDE wet clean control of auxiliary 2 output. If “2DRAIN” is selected that means that the auxiliary 2 output is reserved for controlling a second independent drain (not for integrated reuse – you should select “1DRAIN” for integrated reuse). Also, if “2DRAIN” is selected. the WE-6 will not permit programming an auxiliary 2 step.

F232059

Operation

WE-6 Microcomputer

The WE-6 microcomputer control is a fieldprogrammable solid-state control capable of storing and running up to 39 preprogrammed ready-to-use cycles.

Cycle 01 is a test cycle used to verify proper operation of the machine. With the exception of Cycle 39, the remaining cycles are complete wash cycles or specialty cycles designed to handle various fabrics at specific water temperatures and levels. Cycle 39 is designed to test an external chemical injection supply system.

A detailed description of the cycles can be found in the

Programming section of this manual under Preprogrammed Cycles. (If this washer-extractor’s

computer has been equipped with special preprogrammed cycles, a separate insert listing these cycles has been included in the resealable plastic bag which contained this manual.)

Never turn the power off while the computer mode switch is in the PROGRAM position. Such action will disorder portions of the programmed data, necessitating reprogramming of some or all of the existing cycles. Always return the mode switch to RUN position before turning the power off.

LED Display

The WE-6 microcomputer has a six-digit LED display. References to display indications pertain to the first four digits of the display, reading left to right. The last two digits on the right side of the display will indicate either the last cycle used or the current cycle in progress. Refer to Figure 3.

Operation

Start-Up

Turn on the main power source (circuit breaker or cutoff switch on the wall).

When AC power is turned on, the front panel display will show the program (ROM) identification code.

This identification code will appear for approximately five seconds. Then the computer display will flash “POWER” and “WA I T ” alternately for two minutes.

The display will then show “NEXT00” to indicate that a cycle can be selected. This display will be shown at all times that power is on between cycles, indicating that the door-unlock solenoid will function if the doorunlock button is pressed. The washer-extractor is then ready for loading and unloading.

Opening Door

Use left hand to press and hold the door-unlock button located on the top of the doorbox cover. Use right hand to turn door handle upward and swing the door right to open. Refer to Figure 5.

CAUTION

Be careful around the open door, particularly when loading from a level below the door. Impact with door edges can cause personal injury.

SW025

Load the washer-extractor to full capacity whenever possible, but do not exceed the rated dry-weight capacity of the machine if the fabric to be washed is quite dense, closely woven, and heavily soiled. Overloading can result in an inferior wash. The operator may need to experiment to determine load size based on fabric content, soil content, and level of cleanliness required.

Partial loads can cause greater machine wear than full loads. Partial loads, if necessary, should only occur at the end of the day.

When loading is complete, ensure that all fabric is inside the basket. Then close and lock the door.

Figure 5

NOTE: When washing items which may disintegrate or fragment, such as mop heads or sponges, use laundry nets to prevent drain blockage.

Dry supplies are placed in the supply dispenser compartment cups prior to the start of each cycle.

Liquid supplies can be injected directly into the supply dispenser by an external chemical supply system.

Supply dispenser compartment cups must not be removed when an external chemical injection supply system is attached to the washer-extractor.

Cycle Selection

NOTE: Press keys at their centers just hard enough to activate them.

Find the cycle number of the desired wash cycle from the Standard Cycle Charts in the Programming section of this manual. Cycle numbers must be twodigit numbers from 01 to 39.

Press the numbers desired on the keyboard and note that these numbers are displayed after “NEXT”.

When keys are pressed on the keyboard, a beep will be heard. If an error is made, press the numbers again. As numbers are entered, they move from right to left on the display.

To begin the cycle at any step other than the first step, press the Advance key to advance through the cycle to the desired starting point. (The Advance key is enabled at the factory and can be disabled at the laundry site.) Then press the Start key.

It is possible to skip to the next step in a cycle, with the exception of a drain step; drain steps must be allowed time to complete.

When the display shows the step desired to begin the cycle, press the Start key.

If the door is not locked, the display will indicate “CLOSE” and “DOOR”. If this occurs, be sure the door is closed and locked and press the Start key again.

If the LED indicator lights for the computer outputs indicate that one or more outputs are activated but the washer-extractor is not functioning according to the output or outputs indicated, contact a service technician.

As water fills the washer-extractor, one or more of the indicator lights located to the left of the keyboard will come on and stay on until the required water level is reached. LED dots located in the upper left corner of the last three digits on the right of the display will illuminate to indicate the water level(s) reached:

NOTE: If the washer-extractor is equipped with both steam and electric heat, the selector switch on the valve panel must be in the correct position for the desired heat source, down for steam heat, up for electric heat.

Cycle Execution

To start the selected cycle, press the Start key. If the selected cycle number is not in the computer memory, the display will show “NCYC”. If this happens, select another cycle. Otherwise, the display will now show the first step. For example, if the display reads

“HL01”, “HL” represents a hot fill to low level, and “01” indicates that this is the first step of the cycle.

As the cycle proceeds, the display will show the function being executed, the step number, and the cycle number selected. Pressing the Edit Cycle key while the cycle is running will cause the display to show the remaining cycle time in minutes. Pressing this key again will return the display to normal.

● When the indicator dot in the last digit on the

right is lit, the low water level has been reached.

● When the dot in the next-to-the-last digit is lit,

medium water level (optional) has been reached.

● When the dot over the third digit from the right

has been lit, high level has been reached.

The cycle will continue until its completion. Then the display will show “DONE”.

Operation

Test Cycle

Cycle number 01 is a test cycle used to analyze washer-extractor functions. Refer to the Programming section of this manual.

Step 01 in cycle number 01 is a cold fill to low level. This step is designed to give not quite enough time to complete a fill, causing the display to read “FILL”. Press the Start key to continue the fill, and the test cycle will proceed.

Step 02 in the test cycle is a drain step. Again, the time allotted is shorter than it would be in a normal cycle. The display will read “EMTY”. To proceed, press the Start key.

The steps in the test cycle are relatively short, with the exception of steps 03, 20, 22, 24, 25, 26, and 29. These can be shortened by pressing the Advance key to go on to the next step.

The operator may skip to any next step in the cycle with the exception of a drain step: Drain steps must be allowed to complete. To skip forward in the test cycle, press the Advance key.

Wet Clean Testing

Wet clean processing outputs are tested through the energizing of the Auxiliary 1 output in step 17 and Auxiliary 2 output in step 18. Steps after step 28 are designed to test water reuse processing, if this option is installed. If it is not, press the Stop key to abort the cycle.

NOTE: Prompts for “1DRAIN” and “WET CL” must be selected when prompting the WE-6 microcomputer in order for steps 17 and 18 to work properly for wet clean processing.

NOTE: The Advance feature may be disabled. Refer to System Programming in the Programming section of the manual.

WARNING

Stop Routine

The operator can select the agitation which will be in effect for the entire Stop routine. This will help prevent tangling of the load and provide maximum control. Three agitations are available for the Stop routine. They are as follows:

Wash 1

● 18 seconds forward

● 3 seconds pause

● 18 seconds reverse

● 3 seconds pause

● sequence repeated

Wash 2

● 3 seconds forward

● 27 seconds pause

NOTE: The forward and reverse times differ slightly for the Wash 1 selection. These times give the best results during the Stop routine when no water is in the washer-extractor.

To select the agitation in the Stop routine, program a Wash 1, 2, or 3 step for 1 second. The washer-

extractor will begin refilling to the most recent water level if the time is more than 1 second. If the most

recent wash type was Wash 4, 6, or 7, the WE-6 will default to no agitation (Wash 3) during the Stop routine.

NOTE: If the desired action is not programmed in the final cycle step, the computer will default to the most recent action in the cycle. If the cycle stops prematurely, the most recent action at the time the cycle is interrupted will be in effect during the Stop routine.

The display will read “W1-cc”, “W2-cc”, or “W3-cc” for Wash 1, Wash 2, or Wash 3 action during the entire Stop routine until the final 10 seconds. (The “cc” here stands for the current cycle number and will be represented by numbers in the actual display.) During the final ten seconds, the display reads “STOPcc”. The display will then read “DONEcc”. At that point, the door can be opened.

● 3 seconds reverse

● 27 seconds pause

● sequence repeated

Wash 3

● no agitation

Operation

Balance Detection

The washer-extractor may be equipped with either of two balance detection systems: (1) a balance sensor detection system or (2) an inverter drive balance detection system.

Balance Sensor Detection

If the washer-extractor is equipped with the balance sensor detection system, the optical sensor installed on a bracket on a shock absorber signals the computer to slow the washer-extractor when an out-of-balance load occurs during extract.

If the balance sensor is tripped, the out-of-balance LED indicator located in the upper left corner of the first digit of the display will light and will remain lighted until the end of the extract step. This indicator tells the operator that an out-of-balance condition existed during an extract step. The washer-extractor will attempt to balance three times during an extract step.

If on the third attempt the out-of-balance condition continues, the washer-extractor will advance to the next step. (If the next step is another spin step, it will be skipped also.)

Inverter Drive Balance Detection

If the washer-extractor is equipped with the inverter drive balance detection system, balance is detected by the inverter drive during a drain step as opposed to an extract step. The WE-6 microcomputer will make up to seven attempts to balance the load during a drain step. During the final balance attempt, the out-ofbalance LED indicator located in the upper left corner of the first digit of the display will light. The indicator will remain lighted until the drain step is complete.

If on the seventh attempt the load is not balanced, the washer-extractor will continue to the next step in the cycle following the drain step that is not a spin step. Therefore, if one spin step or two or more consecutive spin steps follow, all will be skipped if seven attempts to balance the load in the drain step fail. High speed steps include medium, H1, H2, and H3 spin steps.

NOTE: The computer cannot advance through a drain step, nor will the computer allow starting a cycle in a spin step.

NOTE: A drain step must be programmed prior to a high speed step to allow for inverter drive balance detection. Otherwise, spin steps will be skipped by the computer.

If the washer-extractor is equipped with the inverter drive balance detection system, a special balance switch serves to remove power to the machine. This means that if the washer-extractor balance “passes” the inverter drive balance detection system at the drain step but the balance switch detects an out-of-balance load condition at the extract step, power will be removed from the washer-extractor.

At this point, the LED display goes blank on the WE-6 microcomputer, and the washer-extractor coasts to a stop. Such a condition indicates a serious problem. Contact a service technician before attempting to restore power to the washer-extractor.

Operation

Temperature Display

The temperature display can be prompted to display in Fahrenheit or Centigrade. Refer to System Programming in the Programming section of this manual.

To display temperature, press the Display Temp key. The display will read “F” or “C” and the temperature as long as the key is pressed. The computer will update the display automatically.

Calibrating the WE-6 Temperature Circuit

1. Open the control compartment to gain access to the WE-6 computer board.

2. Viewing the WE-6 computer board from the rear, locate the blue rectangular plastic component with a white plastic screw head in the center. This is the temperature calibration potentiometer. Turning this screw head adjusts the temperature reading.

3. Fill the machine sump with water and place an accurate temperature sensor in the water to provide a measurement of the actual water temperature. The WE-6 temperature readout is then adjusted to match this to the nearest unit. It is easiest to program a Wash 3 (no agitation) for 10 seconds (to prevent rotation and subsequent damage to the temperature sensor), then a cold fill to high level, followed by a Wash 3 for 9 minutes and 99 seconds. Do not press STOP. Calibration must be completed before the last wash step finishes. Remove power to machine after calibration until computer goes off to prevent rotation when the cycle ends.

4. Start the cycle. When the water level is reached (and the external temperature sensor is submerged), press the DISPLAY TEMP key on the WE-6 keypad. The display will show a reading in either degrees F or degrees C, or the conversion will have to be made by calculation as follows:

Degrees F = (Degree C x 9/5) + 32 Degrees C = (Degrees F - 32) x 5/9

5. While pressing the DISPLAY TEMP key, use the screwdriver to turn the temperature calibration screw until the WE-6 displays the same temperature as the external sensor, which should be accurate at least to the nearest degree. Turning the screw clockwise increases the displayed temperature.

6. When the temperatures match, calibration is completed. Close the control compartment and remove the external temperature sensor. To prevent rotation, DO NOT PRESS STOP; instead remove power to the machine until the computer goes off.

*As an alternative, if an external sensor is not available, measure the temperature of the inflowing water, and follow step 5.

Operation

Error Recovery Routine

When the computer detects an error, it will stop running the current step and display a message to indicate what type of error was found:

● “FILL” indicates that the washer-extractor did

not fill within the allotted time.

● “EMTY” indicates that the washer-extractor did

not drain in the allotted time.

● “TEMP” indicates that the temperature sensor

has recognized an over-temperature-limit condition.

● “ME” indicates that the computer has detected a

problem with the cycle information. The cycle must be edited.

● “WATER” indicates that the WE-6

microcomputer senses low, medium, or high water level at the end of the Stop routine.

● “DRTEMP” indicates that the WE-6 has detected

water temperature over 160°F (71°C) in a “drain to reuse” step. Instead of draining to a tank, the computer gives this error message. The cycle must be edited so the temperature is below 160° F (71°C) upon entering a reuse drain step (“Da” or “Db”).

All outputs remain off while the message displays, and the door cannot be unlocked.

NOTE: The WE-6 microcomputer will not allow the door to be opened while there is water in the washer-extractor.

Each of these errors is considered to be recoverable. The operator has two minutes to respond to the error condition (except in the case of “WATER”). During this time, the computer will turn the signal (buzzer) relay on and off at the rate of one second on and one second off to alert the operator to the error condition. The washer-extractor may be restarted by pressing the Enter key. Pressing the Enter key will restart the cycle step for the originally programmed time period. The cycle may be aborted by pressing the Clear key. After aborting the cycle, the computer will go to the normal stop routine. If the operator does not respond to the error condition within the allocated two minutes, the computer will automatically abort the cycle.

NOTE: The “TEMP” alarm can be recovered only after the temperature falls below the alarm level.

Certain error conditions are considered to be nonrecoverable:

● If the door opens during a cycle, the computer

will display “DOOR”. The operator must close the door.

Then, after the computer has detected that the door is closed, it will automatically abort the cycle and go to the normal Stop routine.

● “OVERHT” will be displayed when the computer

detects an open or shorted temperature input circuit or temperatures are outside of the washerextractor’s allowable limits. Contact a service technician.

Operation

Thermal Overload Indicator

To protect the AC drive from damage due to excessive temperature, a thermal limit switch is embedded in the drive box.

If the thermal limit switch is tripped due to damaging conditions, the “Drive Thermal Indicator” light located in the WE-6 control module will light and power will be removed from the drive. The AC drive thermal limit switch MUST be manually reset. Refer to the following for location and instructions.

Before resetting the thermal overload switch, determine the reason for the overload. The following is a partial list of possible problems:

● Bad motor bearings.

● Motor cooling fan blocked or not operating.

● Excessively dirty motor (lint build-up, for

example).

● Room temperature higher than 104°F (40°C).

● Dirty fan filter.

● Fan not operating properly.

Resetting Thermal Overload Switch

1. Remove the main power from the machine.

2. Locate the AC drive box and remove the cover. The AC drive box enclosure is located at the rear

in the upper, left-hand corner of the machine as seen from the rear.

3. Locate the thermal limit switch in the AC drive box and press the red reset button located on the switch.

The thermal limit switch is mounted in the center of the left side wall of the AC drive box.

4. Replace the cover and return power to the machine.

● Fan not installed properly.
