WASHER
INDICATION DISPLAY
EXPLANATION AND RECOMMENDED PROCEDURE
NO WATER DETECTED ENTERING
WASHER
The appropriate water level is not reached in the desired
time. The fill sequence is as follows:
1. Washer attempts to fill for 2 minutes; if appropriate
water level is not achieved, “lo H2O” is displayed
for 2 minutes or until cycle is reselected.
2. Washer then attempts to fill again for 2 minutes;
if appropriate water level is not achieved, “lo H2O”
is displayed for 2 minutes or until cycle is reselected.
3. Washer then attempts to fill again for 2 minutes;
if appropriate water level is not achieved, washer
will pump out and display F20.
Possible Causes
– No water to washer; faucet(s) turned off.
– Defective hot and/or cold valve(s).
– Plugged or kinked inlet hoses or valves.
– Pressure switch or pressure switch hose
damaged, kinked, or disconnected.
– Electrical connection from CCU (PS8) to pressure
switch damaged.
– Blocked inlet from the dispenser to the tub.
Procedure
1. Clear error code.
2. Unplug washer or disconnect power.
3. Check incoming water pressure at faucet.
4. Check inlet hoses for possible leaks.
5. Make sure pressure switch hose is in good condition
and properly connected to tub and pressure switch.
6. Check that there is not a drain siphon problem.
7. Perform continuity test on wire harness connections from
CCU to inlet valves (VCH7 & DI6) and pressure switch (PS8).
8. Check inlet valves by running a diagnostic test.
9. Check that the pump is not running while the
washer is filling.
10. Verify pressure switch operation by accessing
Help Mode while running a paid cycle.
LONG DRAIN
The drain time exceeds 8 minutes without reaching
reset level in pressure switch.
NOTE:
■
Suds can cause delays in draining, indicated by an
alternating display of “SudS” and a countdown timer.
Washer drains for 4 minutes, pauses 5 minutes, then
tries again for 4 additional minutes of draining. F21
will display if washer does not drain. (Normal drain
takes less than 2 minutes).
Possible Causes
– Damaged or blocked pump.
– Drain hose blocked or exceeds recommended height.
– Poor connection between CCU (DP2) and drain pump.
Procedure
1. Clear error code.
2. Unplug washer or disconnect power.
3. Make sure the drain hose is not sealed in the standpipe.
4. Make sure the drain height is not more than 8 ft
above the base of the washer.
5. Check the drain hose and make sure it is not
plugged or kinked.
6. Check the drain pump for foreign objects.
7. Check the electrical connection between the pump
and the CCU (DP2).
8. Check the pump using a diagnostic mode.
If all the above are OK and pump is powered but does
not pump water or water flow is poor, replace the pump.

INDICATION DISPLAY
EXPLANATION AND RECOMMENDED PROCEDURE
DOOR LOCK ERROR
Washer will make several attempts to lock the door,
then customer will be asked to open door, clear
obstructions, shut door, and reselect cycle. Washer
will attempt to lock the door again. This procedure
can repeat 2 times before customer loses vend and
washer resets. If entire procedure happens twice
without a successful door lock, F22 will appear.
Possible Causes
– Misaligned or broken door latch.
– Electrical connections from CCU (DLS2, DL3)
to door lock are damaged.
– Misaligned, broken, or overtightened door hook.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Make sure that the latch is secured to the front panel.
4. Check for misaligned, broken, cracked, or loose
door hook.
5. Check the electrical connections between CCU
(DLS2, DL3) and latch.
If the latch fails to lock after checking all of the above,
replace the latch.
TEMPERATURE SENSOR ERROR
Water temperature sensor value is out of range (23°F
to 217°F [-5°C to 103°C]).
NOTE:
To find correct Ohm reading, refer to the
Water Temperature Sensor section, page 14.
Possible Causes
– Water temperature sensor damaged.
– Electrical connections from CCU at SET2
to temperature sensor damaged.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Perform Ohm test on Water Temperature Sensor and
harness connection. This reading can be taken from
the cable attached to CCU at SET2.
If the water temperature sensor is out of range,
replace it.
