Throughout this manual and on machine decals, you will find precautionary statements (“CAUTION,”
“WARNING,” and “DANGER”) followed by specific instructions. These precautions are intended for the personal
safety of the operator, user, servicer and those maintaining the machine.
aDANGER
Danger indicates the presence of a hazard that will cause severe personal injury, death or substantial property
damage if the danger is ignored.
aWARNING
Warning indicates the presence of a hazard that can cause severe personal injury, death or substantial property
damage if the warning is ignored.
aCAUTION
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.
NOTE

important but not hazard related.
General Safety Precautions
In the interest of safety, some general precautions relating to the operation of this machine follow.
• Failure to install, maintain and/or operate this product according to the manufacturer’s
instructions may result in conditions which can produce serious injury, death and/or property
damage.
• Do not repair or replace any part of the product or attempt any servicing unless specifically
recommended or published in this Service Manual and unless you understand and have the
skills to carry out the servicing.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the product is properly grounded and to reduce the risk of fire,

Safety Information
Always contact your dealer, distributor, service agent or the manufacturer about any problems or conditions you do
not understand.
Important Safety Instructions
1. Read all instructions before using the washer-extractor.
2. Refer to the GROUNDING INSTRUCTIONS in the INSTALLATION manual (supplied with your washer-
extractor) for the proper grounding of the washer-extractor.
3. Do not wash textiles that have been previously cleaned in, washed in, soaked in or spotted with gasoline, dry-
cleaning solvents or other flammable or explosive substances. 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.
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 washer-extractor, 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.
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the washer-extractor before servicing.
• Never start the washer-extractor with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer-extractor is properly grounded.

WARNING
Repairs that are made to your products by unqualified persons can result in hazards due to
improper assembly or adjustments subjecting you or the inexperienced person making such
repairs to the risk of serious injury, electrical shock or death.
W007
WARNING
If you or an unqualified person perform service on your product, you must assume the
responsibility for any personal injury or property damage which may result. The manufacturer
will not be responsible for any injury or property damage arising from improper service and/or
service procedures.
W008

Safety Information
6. Do not allow children to play on or in a washer-extractor. Close supervision of children is necessary when the
washer-extractor is used near children.
7. Before the washer-extractor is removed from service or discarded, remove the door to the washing
compartment.
8. Do not reach into the washer-extractor if the wash basket is moving.
9. Do not install or store the washer-extractor where it will be exposed to water and/or weather.
10. Do not tamper with the washer-extractor’s controls.
11. Do not repair or replace any part of the washer-extractor 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.
12. To reduce the risk of an electrical shock or fire, DO NOT use an extension cord or an adapter to connect the
washer-extractor to an electrical power source.
13. Use the washer-extractor only for its intended purpose, washing clothes.
14. ALWAYS disconnect the washer-extractor from its electrical supply before attempting any service.
15. Install the washer-extractor according to the INSTALLATION INSTRUCTIONS. All connections for water,
drain, electrical power and grounding must comply with local codes and, when required, be made by licensed
personnel.
16. To reduce the risk of fire, textiles which have traces of any flammable substances such as vegetable oil,
cooking oil, machine oil, flammable chemicals, thinner, etc. or anything containing wax or chemicals such as
in mops or cleaning cloths, must not be put into the washer-extractor. These flammable substances may cause
the fabric to ignite.
17. Do not use fabric softeners or products to eliminate static unless recommended by the manufacturer of the
fabric softener or product.
18. Keep the washer-extractor in good condition. Bumping or dropping the washer-extractor can damage its safety
features. If this occurs, have the washer-extractor checked by a qualified service person.
19. Replace worn power cords and/or loose plugs.
20. Be sure that 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.
21. The loading door MUST BE CLOSED any time the washer-extractor is to fill, tumble or spin. DO NOT by-
pass the loading door switch and permit the washer-extractor to operate with the loading door open.
22. Always read and follow the manufacturer’s instructions on packages of laundry and cleaning aids. Heed all
warnings and 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).
23. Always follow the fabric care instructions supplied by the textile manufacturer.
24. Never operate the washer-extractor with any guards and/or panels removed.
25. DO NOT operate the washer-extractor with missing or broken parts.
26. DO NOT by-pass any safety devices.
27. Failure to install, maintain and/or operate this washer-extractor according to the manufacturer's instructions
may result in conditions that can produce bodily injury and/or property damage.
NOTE: The WARNING 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 and operating the washer-extractor.
Any problems or conditions not understood should be reported to the dealer, distributor, service agent or the
manufacturer.

TURN THE MAIN
POWER TO THE
MACHINE OFF.
DOES THE WATER
SHUT OFF?
THIS IS AN ELECTRICAL ISSUE.
DOES THE CORRESPONDING
LIGHT ON THE FUSEBOARD STAY
ON CONTINUOUSLY AFTER THE
DOOR IS CLOSED AND THE ACH
HAS BEEN ENERGIZED (E.G., IF
THE COLD SPRAY VALVE IS IN
QUESTION, IS THE CS LIGHT
STAYING ON)?
YES
THIS IS A MECHANICAL ISSUE.
REPLACE OR REPAIR THE
MECHANICAL PARTS OF THE
VALVE.
CHECK FOR MISWIRING AT THE
FUSEBOARD OR FOR A SHORT
ON THE WIRE THAT
ENERGIZES THE RESPECTIVE
VALVE (E.G., IF YV1 STAYS
ENERGIZED BUT THE COLD
FILL LIGHT ISN'T LIT ON THE
FUSEBOARD, CHECK THE
WIRING BETWEEN J5-1-2 AND
J15-1-1).
NO
Note: This information applies to the four main fill valves as well as the 4-way supply valves.
The first task in this process is to determine which valve is staying on. If it is one of the four
main valves (i.e., hot spray, hot fill, cold spray or cold fill), this may be done by individually
shutting off the water supply to each valve. If it is a supply valve that is staying open, find
the location in the dry supply box where the water is flushing into and follow the hose back
to the solenoid. Once the valve has been identified, proceed as follows:
YES
CHECK THE RIBBON CABLE
BETWEEN THE COMPUTER AND
THE FUSEBOARD. REPLACE THE
RIBBON CABLE IF NEEDED. IF
THE RIBBON CABLE IS OKAY,
REPLACE THE COMPUTER.
YES
NO
THERE IS A POSSIBILITY THAT THE
FUSEBOARD IS CONTAMINATED. TRY
CLEANING IT. IF THE TEST MENTIONED
IN THE PREVIOUS STEP IS STILL
UNSUCCESSFUL, REPLACE THE
FUSEBOARD.
