NO WATER DETECTED ENTERING WASHER
OR PRESSURE SWITCH TRIP NOT DETECTED
Water level is not reached within a defined time
in normal wash cycle.
Possible Causes/Procedure
If there is no water in the washer:
– 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 washer:
– Verify drain pump operation.
– Remove hose from pressure switch. Dislodge any
debris buildup in the hose inside the outer tub.
– Verify that the pressure switch hose is in good
condition and properly connected to tub and
pressure switch.
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.
LONG DRAIN
A 1 0
If the drain time exceeds 4 minutes, the water valves
turn off.
NOTE:
Rotate the cycle control knob to clear the display.
Possible Causes/Procedure
1. Check the drain hose and make sure it is not
plugged or kinked.
2. Unplug washer or disconnect power.
3. Remove hose from pressure switch. Dislodge any
debris buildup in the hose inside the outer tub.
4. Check the electrical connections at the pump and
make sure the pump is running.
5. Check the drain pump filter for foreign objects.

EXPLANATION AND RECOMMENDED PROCEDURE
NO WATER DETECTED ENTERING WASHER
OR PRESSURE SWITCH TRIP NOT DETECTED
Water level is not reached within a variable time
(EEPROM parameter) in Whirlpool factory test.
Possible Causes/Procedure
If there is no water in the washer:
– 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 washer:
– Verify drain pump operation.
– Remove hose from pressure switch. Dislodge any
debris buildup in the hose inside the outer tub.
– Verify that the pressure switch hose is in good
condition and properly connected to tub and
pressure switch.
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 lasts for more
than 2 seconds. In an overflow condition, the door
remains locked and the drain pump runs constantly;
after 10 minutes, door will be unlocked in order to cut
off the valves' power. Then if overflow still occurs, start
pump again. Turn off hot and cold water faucets and
unplug the washer 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 valve, 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 shutoff.
7. Check the pressure switch for proper operation.
8. Remove hose from pressure switch. Dislodge
any debris buildup in the hose inside the outer tub.
Debris inside the hose will not allow the switch to
sense a pressure change.
