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:

1. Read all instructions before using the washerextractor.

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.

W023E

23. Water Running Continuously with Machine Power Off

Water Running Continuously With Machine Power Off

With electrical power removed from the machine, water is running continuously into compartment 1 of the supply dispenser.

Using the “Water Running Continuously” schematic, follow the hose from compartment 1 of the supply dispenser back through the vacuum breaker and the Y-connector to the hot water valve at V9 and the cold water valve at V10.

To determine which of the valves is leaking, turn off the water supply to each of the valves, one valve at a time. When the water supply is removed from the leaking valve, the water running into compartment 1 of the supply dispenser will stop.

For example, if water is running into compartment 1 of the supply dispenser continuously, when the water supply is removed from the hot water valve, the water continues to run into compartment 1. However, when the water supply is removed from the cold water valve, the water running into compartment 1 stops. Therefore, the cold water valve is the leaking valve.

With electrical power removed from the machine, water is running continuously into compartment 2 of the supply dispenser.

Using the “Water Running Continuously” schematic, follow the hose from compartment 2 of the supply dispenser back through the vacuum breaker to the cold water valve at V4.

Install a valve repair kit onto the cold water valve or replace the valve. Refer to the Parts manual for your washer-extractor for valve and valve repair kit part numbers.

With electrical power removed from the machine, water is running continuously into compartment 3 of the supply dispenser.

Using the “Water Running Continuously” schematic, follow the hose from compartment 3 of the supply dispenser back through the vacuum breaker to the cold water valve at V5.

Install a valve repair kit onto the hot water valve or replace the valve. Refer to the Parts manual for your washer-extractor for valve and valve repair kit part numbers.

With electrical power removed from the machine, water is running continuously into the bottom of the washer-extractor.

To determine which of the valves is leaking, turn off the water supply to each of the valves, one valve at a time. When the water supply is removed from the leaking valve, the water running into the bottom of the washer-extractor will stop.

For example, when the water supply is removed from the hot water valve at V1, the water continues to run into the bottom of the washer-extractor. However, when the water supply is removed from the cold water valve at V2, the water running into the bottom of the washerextractor stops. Therefore, the cold water valve at V2 is the leaking valve.

Once the leaking valve(s) has been determined, install a valve repair kit onto the leaking valve or replace the leaking valve. Refer to the Parts manual for your washer-extractor for valve and valve repair kit part numbers.

Once the leaking valve(s) has been determined, install a valve repair kit onto the leaking valve port or replace the entire leaking valve. Refer to the Parts manual for your washer-extractor for valve and valve repair kit part numbers.
