TROUBLESHOOTING AND DIAGNOSTICS
POSSIBLE CAUSE/TEST PROBLEM
WON'T POWER UP 1. Unplug unit for more than 5 seconds, then plug back in.
(Verify lid is closed) 2. Check 120V at outlet.
3. Check harness connections.
4. Check 120V between 9-pin connector and ground.
WON’T START 1. Verify unit is not in Pause or Service Mode.
(Verify lid is closed) 2. Unplug unit for 5 seconds, then plug back in.
3. Verify power between 9-pin connector and ground.
CONTROL LOOPS THROUGH 1. Unit is in Service Mode. Unplug for more than
CYCLE REPEATEDLY 5 seconds, then plug back in.
WON’T FILL 1. Check installation. Verify water supply. Verify valves are
(Verify lid is closed) turned on.
2. Check screens on water valve.
3. Operate Actuator and Switch test.
4. Check resistance measurements with unplugged unit.
5. Check connections on water valves.
6. Verify 120V at valves during fill. If no voltage exists and
above solutions fail, replace electronic control.
OVERFILLS 1. Check Water Level switch hose connections.
2. Check Water Level switch using ohmmeter.
3. Blow into Water Level switch hose to tub to dislodge lint in
air dome.
4. Do not adjust Water Level switch. Adjusting Water Level
switch will cause flooding.
5. Check connections on Water Level switch.
6. If machine still overfills replace Water Level switch.
7. If above solutions fail, replace electronic control.
WON’T AGITATE OR AGITATOR 1. Perform Actuator and Switch Test for Dry Agitate.
ROTATES IN ONE DIRECTION 2. Verify 120V between the control yellow wire (counterclock-
(Verify lid is closed) wise) and ground and between the red wire (clockwise)
and ground. Verify power at the motor.
If the voltage is at the motor and the unit does not agitate
replace motor.
If no voltage comes from the control replace the electronic
control.
NOTE: The voltage pulsates; it does not stay on. It is diffi
cult to check with a Digital Volt Meter.
WRONG AGITATE SPEED 1. Check belt tension. There should be light deflection
(approximately 1/8") when pressed. (Loose belt will also
cause black mark on inside of cabinet.)
TROUBLESHOOTING
