Section 1

Safety Information

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.

a DANGER

Danger indicates an imminently hazardous situation that, if not avoided, will cause severe personal injury or death.

a WARNING

Warning indicates a hazardous situation that, if not avoided, could cause severe personal injury or death.

a CAUTION

Caution indicates a hazardous situation that, if not avoided, may cause minor or moderate personal injury or property damage.

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

The word “NOTE” is used to communicate installation, operation, maintenance or servicing information that is important but not hazard related.

In the interest of safety, some general precautions relating to the operation of this machine follow.

WARNING

• 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, electric shock, serious injury or death.

W006R2



WARNING

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.

W460

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

Always contact your dealer, distributor, service agent or the manufacturer about any problems or conditions you do not understand.

Important Safety Instructions

WARNING

To reduce the risk of fire, electric shock, serious injury or death to persons when using your washer, follow these basic precautions:

W023E

4

1. Read all instructions before using the washer-extractor.

2. Refer to the GROUNDING INSTRUCTIONS in the INSTALLATION manual (supplied with your washerextractor) 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, drycleaning 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.

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 shutoff 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 bypass 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.

5. Water Runs Continuously into the Washer-Extractor (120 Volt Control)

(Either when the machine is in cycle or not)

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:

23. Excessive Cycle Time

When experiencing excessive cycle time, there are three main causes which are as follows: a. Fill Time:

(1) Check for excessively long fill times. Refer to the “Fill Alarm Analysis” flowchart if any are found.

(2) Check for excessively long programmed fill times.

NOTE: All pre-programmed fill times are for 5 minutes. Any fill should easily complete during this time.

b. Drain Time:

(1) Look for excessively long programmed drain times (i.e., greater than one minute).

NOTE: Any drain step should not exceed 30-40 seconds.

c. Unnecessary Programming Steps:

(1) E.g., in the first fill of a cycle, if “S102XX” is programmed for 45 seconds and “S203XX” is programmed for 45 seconds, the two steps can be accomplished together at the same time, saving 45 seconds. Refer to the “Programming Multiple Supply Steps” section of your washer-extractor’s programming manual.

24. Excessive Vibration and/or Noise During Spin

When experiencing excessive vibration and/or noise during a spin cycle, there are three main causes, which are as follows: a. Improper Loading:

(1) Always make sure that full loads are used. Never wash partial loads.

(2) Do not mix various laundry items together in the same wash (e.g., do not wash towels and sheets together).

b. Improper Installation:

(1) Make sure that the washer-extractor is anchored to a flat, level surface with the proper depth of concrete.

(2) Tighten all anchor bolts and nuts. Make sure that they are of the correct size and grade.

(3) Make sure that the washer-extractor is grouted properly.

(4) Refer to your washer-extractor’s installation manual for exact installation specifications.

c. Faulty Front and/or Rear Bearings:

(1) Check the front and rear bearings’ noise factor.

(2) Lift up on the basket at the front of the tub. Check for any up and down play that would indicate bearing wear.

(3) Replace the bearings as needed.


Troubleshooting

25. Stop/Done Situation in Mid Cycle

If the washer-extractor stops in mid-cycle, this indicates that the computer saw an open circuit at the door lock microswitch.

Check the door lock microswitch for loose connections or broken wires. Repair the wires or replace the microswitch as needed.

26. Power Wait Situation in Mid Cycle

A power wait situation in mid cycle indicates that the machine’s computer lost power.

a. Check the computer’s battery back-up. Replace the battery as needed.

b. If the battery is okay, check for voltage at the white plug by the transformer on the output board. Voltage present should either be 120 or 220 VAC, depending on the control voltage.

27. Pumps Turning on in Mid Cycle Without Being Programmed to Do So

Pumps turning on in mid-cycle without being programmed to do so may be the result of resistors on the output board allowing low voltage leaks (between 1 and 40 VAC).

Replace the resistors on the output board (that correspond to the pumps that are turning on in mid cycle) as needed.

Also, veritfy that the supply valve is connected. Removal of a valve from a circuit will result in a feedback voltage that can trigger the pumps to turn on.
