NO WATER DETECTED ENTERING MACHINE OR PRESSURE SWITCH TRIP NOT DETECTED

Water level is not reached within a variable time (EEPROM parameter) in whirlpool factory test

F01

Possible Causes/Procedure

 If there is no water in the unit:

– Make sure that both valves at the water source(s) are turned on all the way.

– Check for plugged or kinked inlet hoses or plugged screens in the inlet valves.

– Verify inlet valve operation.

 If there is water in the unit:

– Verify drain pump operation.

– Verify that the pressure switch hose is in good condition and properly connected to tub and pressure switch.

– Remove hose from pressure switch. Dislodge any debris build up in the hose inside the outer tub.

1. Verify there is not a siphon problem.

2. Unplug washer or disconnect power.

3. Verify wire harness connections to inlet valves, pressure switch, drain pump and Central Control Unit (CCU).

4. Check all hoses for possible leaks.

5. Plug in washer or reconnect power

6. Verify pressure switch operation.

7. Verify CCU operation by running a Quick Diagnostic Test or any cycle

OVERFLOW CONDITION

Overflow level has been reached, and last for more than 2 seconds. In an overflow condition, the door remains locked and

the drain pump runs constantly, and after 10 minutes, door will be unlocked in order to cut off the valves power. Then if

overflow still happens, start pump again. Turn off hot and cold water faucets and unplug the unit before servicing.

Possible Causes/Procedure

1. Check the drain hose and make sure it is not plugged or kinked.

2. Unplug washer or disconnect power, if water still flows into the washer, replace the water valve.

3. Check wire harness connections to the drain pump, pressure switch, water inlet value, and Central Control Unit (CCU).

4. Check/clean drain pump filter of foreign objects.

5. Check for drain pump failure.

6. Check the inlet valve for proper shut off.

7. Check the pressure switch for proper operation.

8. Remove hose from pressure switch. Dislodge any debris build up in the hose inside the outer tub. Debris in side the hose

will not allow the switch to sense a pressure change.
