Safety Information

Precautionary statements (“DANGER,” “WARNING”

Important Safety Instructions

and “CAUTION”), followed by specific instructions,

are found in this manual and on machine decals. These

precautions are intended for the personal safety of the

operator, user, servicer, and those maintaining the

machine.

WARNING

To reduce the risk of fire, electric shock,

serious injury or death to persons when

using your washer, follow these basic

precautions:

DANGER

W023E

DANGER indicates the presence of a

hazard that will cause severe personal

injury, death, or substantial property

damage if the danger is ignored.

1. Read all instructions before using the washer.

2. Refer to the Grounding Instructions in the

installation manual for the proper grounding of

the washer.

3. Do not wash textiles that have been previously

cleaned in, washed in, soaked in, or spotted with

gasoline, dry-cleaning solvents, or other

WARNING

injury, death, or substantial property

damage if the warning is ignored.

flammable or explosive substances as they give

off vapors that could ignite or explode.

4. Do not add gasoline, dry-cleaning solvents, or

other flammable or explosive substances to the

wash water. These substances give off vapors that

could ignite or explode.

CAUTION

5. Under certain conditions, hydrogen gas may be

produced in a hot water system that has not been

used for two weeks or more. HYDROGEN GAS

IS EXPLOSIVE. If the hot water system has not

been used for such a period, before using a

washing machine or combination washer-dryer,

turn on all hot water faucets and let the water

flow from each for several minutes. This will

release any accumulated hydrogen gas. The gas is

flammable; do not smoke or use an open flame

during this time.

CAUTION indicates the presence of a

hazard that will or can cause minor

personal injury or property damage if the

caution is ignored.

Additional precautionary statements (“IMPORTANT”

and “NOTE”) are followed by specific instructions.

IMPORTANT: The word “IMPORTANT” is used

to inform the reader of specific procedures where

minor machine damage will occur if the procedure

is not followed.

6. Do not allow children to play on or in the washer.

Close supervision of children is necessary when

the washer is used near children. This is a safety

rule for all appliances.

NOTE: The word “NOTE” is used to communicate

installation, operation, maintenance or servicing

information that is important but not hazard

related.

7. Before the washer is removed from service or

discarded, remove the door to the washing

compartment.

8. Do not reach into the washer if the wash drum is

moving.

F232161

Safety Information

9. Do not install or store the washer where it will be

exposed to water and/or weather.

19. Replace worn power cords and/or loose plugs.

20. Be sure water connections have a shut-off valve

and that fill hose connections are tight. CLOSE

the shut-off valves at the end of each wash day.

10. Do not tamper with the controls.

11. Do not repair or replace any part of the washer, or

attempt any servicing unless specifically

recommended in the user-maintenance

instructions or in published user-repair

instructions that the user understands and has the

skills to carry out.

21. Loading door MUST BE CLOSED any time the

washer is to fill, tumble or spin. DO NOT

bypass the loading door switch by permitting the

washer to operate with the loading door open.

22. Always read and follow manufacturer’s

instructions on packages of laundry and cleaning

aids. Heed all warnings or precautions. To reduce

the risk of poisoning or chemical burns, keep

them out of the reach of children at all times

(preferably in a locked cabinet).

12. To reduce the risk of an electric shock or fire, DO

NOT use an extension cord or an adapter to

connect the washer to the electrical power source.

13. Use washer only for its intended purpose,

washing textiles.

23. Always follow the fabric care instructions

supplied by the textile manufacturer.

14. ALWAYS disconnect the washer from electrical

supply before attempting any service. Disconnect

the power cord by grasping the plug, not the cord.

24. Never operate the washer with any guards and/or

panels removed.

15. Install the washer according to the Installation

25. DO NOT operate the washer with missing or

broken parts.

26. DO NOT bypass any safety devices.

27. Failure to install, maintain, and/or operate this

washer according to the manufacturer’s

16. To reduce the risk of fire, textiles which have

traces of any flammable substances such as

vegetable oil, cooking oil, machine oil,

instructions may result in conditions which can

produce bodily injury and/or property damage.

flammable chemicals, thinner, or anything

containing wax or chemicals such as in mops and

cleaning cloths, must not be put into the washer.

These flammable substances may cause the

fabric to catch on fire by itself.

NOTE: The WARNINGS and IMPORTANT

SAFETY INSTRUCTIONS appearing in this

manual are not meant to cover all possible

conditions and situations that may occur. Common

sense, caution and care must be exercised when

installing, maintaining, or operating the washer.

17. Do not use fabric softeners or products to

eliminate static unless recommended by the

manufacturer of the fabric softener or product.

Any problems or conditions not understood should be

Operation

Start-Up

Select Cycle

Turn on the main power source (breaker panel or cut-

off switch on the wall). The front panel display should

light up and show “WAIT 00” for 30 seconds followed

by “NEXT 00” which means Select Cycle. This

display will be on at all times that power is on

indicating the machine is ready for loading and

unloading.

Find the cycle number (cycle numbers must be two-

digit numbers) of the desired wash cycle from the

cycle code list provided. Press (do not punch) with

your finger the numbers desired on the keypad and

note that this number is displayed instead of “NEXT”.

When keys are pressed on the keypad, a beep will be

heard. If an error is made, simply press the CLEAR

key and then press the numbers again. As numbers are

entered, they move from right to left on the display.

Display will show “CY12” if cycle 12 is pressed.

NOTE: Throughout this manual, when display

indications are referred to, these indications will

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 process.

NOTE: In order to Clear or Enter data, the display

must be filled – i.e., no blank spaces.

Start Cycle

To start the cycle that has been selected, simply press

the START key. If the cycle number selected is not in

the computer memory, the display will show

“NOGO”. If this happens, select another cycle.

Otherwise, the display will now show the first step.

(Example: “HL01”.) This number indicates the step

number in the cycle as listed in the Selection List. As

the cycle proceeds, the display will show the step

being run and the cycle number selected.

To load the washer, use left hand to press the door

unlock button located on the lower right front of the

control panel. Use right hand to turn door handle to the

right. The door can then be opened.

Load linen until the machine is full. Partial loads are a

waste of energy, water and chemicals and cause

greater machine wear than full loads. If you do not

have enough to fill the basket, wait until you do.

Partial loads, if necessary, should only occur at the end

of the day. Even then, they can usually be held until

the next day when more linen is received.

If the door is not locked, the display will indicate

“DOOR”. If this occurs, be sure the door is closed and

locked and again press the START key. If the computer

starts but the machine does nothing, this indicates the

door hinge microswitch cam may need adjusting. The

door hinge microswitch interlocks all 120 volt power

to the controls with the exception of the computer

itself.

IMPORTANT: If stringy items such as mop heads

are to be washed, laundry nets should be used in

order to prevent fouling of seals and drains.

Once loading is complete (you cannot overload the

machine as far as harm to the machine is concerned;

however, overloading can cause improper mechanical

action and an inferior quality wash), close and lock the

door making sure that all fabric is inside the basket.

The machine should not start or run if the door is not

both closed and locked.

As the cycle progresses, the display will show the step

in the cycle that is being run as well as the cycle

number. In addition, as water is being turned on to fill

the machine, one or more of the four indicator lights

above the first four digits (left to right) in the display

will come on and stay on until the required water level

is reached. Indicator lights above the last two digits on

the right will indicate the water level(s) reached. When

the indicator light in the next to last digit is

illuminated, the low water level has been reached.

Likewise, when the light in the last digit to the right

illuminates, high water level has been reached. The

cycle will continue until its completion and, at this

time, the display will show “NEXT”.

F232161

Operation

Test Cycle

LED Display

Cycle number 01 is a test cycle to check out all

machine functions. The program for the cycle is shown

following the copy of the Program Worksheet.

When display shows letters and/or numbers with or

without the beeper, refer to Table 1. The computer

control in this machine is continuously on the alert for

problems both within the machine and with the total

installation. As the computer sees a problem, it

immediately flashes a letter or number or both on the

display and may activate the beeper as well. Table 1

shows the various displays and what they mean. The

operator should become familiar with these computer

displays.

The first step is a cold fill to low level and is designed

to give not quite enough time to complete a fill and

cause the display to read “FILL”. When the START

key is pressed again, it should continue to fill and

proceed with the test cycle.

The steps in the test cycle are relatively short with the

exception of step 3, step 15, and step 17. These can be

shortened by pressing the ADVANCE key to go on to

the next step.

End of Cycle

When the cycle is completed, the display will show

“NEXT” plus the cycle number just run. To unload the

machine, press the door unlock button and again open

the door to remove contents and place them in the

dryer.

WARNING

NEVER insert hands or objects into

basket until it has completely stopped.

Doing so could result in serious injury.

damage, and may void the warranty.

Figure 2

SW004

Located on the side of the control module is a small

indicator lamp with the above descriptive decal.

If you have difficulty in locating the problem, do not

hesitate to call the factory.

When this lamp is lit, it indicates that there is an open

thermal overload switch on the motor(s) which shuts

off the A.C. power to the computer board thereby

preventing damage to the motor(s) caused by

overheating and/or an overload condition.

This feature is provided to protect the motor and

extend the life of the motor. The thermal overload

switch will automatically reset itself after the

excessive heat condition has subsided; however, before

attempting to restart the machine, always check to find

out the reason for the overload (e.g., machine not fully

drained before spin, defective motor, continual out of

balance condition, low voltage, loss of one phase on

three phase motor, failed bearings, air circulation

blocked to motor fan). The thermal overload switch

should not open under normal operating conditions.

Failure to take corrective action when the indicator

lamp is lit will ultimately result in damage to the

motor(s).
