EEPROM ERROR
A communication error between the Central Control Unit (CCU)
and the EEPROM onboard the CCU occurred.
Possible Causes/Procedure
A power glitch may cause this error.
– Unplug washer or disconnect power for two minutes.
– V
erify CCU ope
ration by running a Diagnostic Test or any
cycle.
PUMP DRIVE ERROR
The pump driver fails to activate.
Possible Causes/Procedure
Replace CCU board.
MAIN RELAYS ERROR
One of the main relays is not working properly.
Possible Causes/Procedure
The relay might be soldered or always open.
– R
eplace CCU board.
MOTOR CONTROL UNIT ERROR
The Motor Control Unit has internal failure; repeating under or
over voltage, or over current conditions. If failure occurs during
high-speed spin the door unlocks after 3 minutes.
Possible Causes/Procedure
1. Unplug washer or disconnect power.
2. Ch
eck wire harness connections between the drive motor and the
Motor Control Unit (MCU), and b etween the MCU and the Ce
ntral
Control Unit (C
CU). Check the motor and do a continuity test.
3. Plug in washer or reconnect power.
4. Check the MCU by looking for operations of the drive motor.
5. Check the drive motor for powered rotations.
6. R
eplace MCU board.
NO WATER DETECTED ENTERING MACHINE
OR PRESSURE SWITCH TRIP NOT DETECTED.
The pressure switch is not tripped after 6 minutes.
Possible Causes/Procedure
If there is no water in the unit:
– M
ake sure that both valves at the wa
ter source(s) are turned
on all the way.
– C
heck for plugged or kinked inlet hoses or plugged screens in
the inlet valves.
– V
erify inlet valve operation.
I
f there is water in the unit:
– V
erify drain pump operation.
– V
erify that the pressure switch hose is in g
ood condition and
properly connected to tub and pressure switch.
1
. Verify there is not a siphon problem.
2
. Press PAUSE/CANCEL twice to clear the display. The
m
achine will drain for 3 minutes before unlocking the door.
3. Unplug washer or disconnect power.
4
. Verify wire harness con
nections to inlet valves, pressure switch,
drain pump and Ce
ntral Control Unit (CCU).
5. Ch
eck all hoses for possible leaks.
6. Plug in washer or r
econnect power
7. Verify pressure switch op
eration.
8. Verify CCU ope
ration by running a Diagnostic Test or any cycle.

DISPLAY EXPLANATION AND RECOMMENDED PROCEDURE
LONG DRAIN
If the drain time exceeds 8 minutes the water valves turn off.
NOTES:
After 4 minutes the “Sd” error will be displayed, then
4 minutes later the “F/21” error code will be displayed.
Press
PAUSE/CANCEL two times to clear the display.
Possible Causes/Procedure
1. C
heck the drain hose and make sure it is not plugged or
kinked.
2. Unplug washer or disconnect power
.
3. Check the electrical connections at the pump and make sure
the pump is running.
4. Check the drain pump filter for foreign objects.
5. Plug in washer or reconnect power
.
6. If the above does not correct the problem, go to step 7.
7. Unplug washer or disconnect power.
8. Replace the pump.
DOOR LOCK ERROR
After 6 failed attempts to lock the door.
Possible Causes/Procedure
Door lock mechanism is broken or removed from door.
Door switch/lock unit failure.
1. Unplug washer or disconnect power.
2. Check door switch/lock unit.
3. Check the wire harness connections to the door switch/lock
unit and Central Control Unit (CCU).
HEATER FAILURE
If the temperature increase during the first 40 minutes is less
than 86°F (30°C).
Possible Causes/Procedure
1. Unplug washer or disconnect power
.
2. Check connection to water heater.
3. Check resistance of heating element, if present on this
model. (abnormal = infinity)
4. Check the water temperature sensor and connection to it.
Refer to the Water
Temperature Sensor section.
WATER TEMPERATURE SENSOR ERROR
If the water temperature sensor (NTC) value is out of range
(23°F to 217°F [-5°C to 103°C]) during the water-heating step
of the
WASH cycle.
NOTE: T
o find correct Ohm reading refer to the Water
Temperature Sensor section.
Possible Causes/Procedure
1. Unplug washer or disconnect power
.
2. Check the water temperature sensor and connection to it.
3. Check resistance of heating element, if present on this
model. (abnormal = infinity)
4. Refer to the Water
Temperature Sensor section.
