What to Check
1. Unplug dishwasher or disconnect
power.
2. Remove drain motor and
dislodge debris from impeller.
Refer to "Fuse Service Check" in
"Meter Check of Loads and Fuses"
section.
Unplug dishwasher or disconnect
power and replace control.
1. Unplug dishwasher or disconnect
power and replace control.
2. Inspect drain motor and
connections for overheating/
shorting. If evidence of overheating/
shorting exists, replace.
1. Check operation in Service
Diagnostics Cycle. Listen for cam
clicking as it rotates or inspect shaft
with mirror to see if rotating during
diverter interval. If rotating, it is
likely the sensor circuit.
2. Unplug dishwasher or disconnect
power and check connections in
Diverter Sensor and Motor circuit
with meter. Fix/replace open
connections/parts.
3. Inspect diverter sensor for
evidence of water or contaminants.
If yes, replace.
Check operation of diverter motor
during diagnostics. Inspect diverter
shaft with mirror. If motor appears
to be on (vibrates, hums), but you
see limited rotation, replace diverter
and seal.
Refer to "Fuse Service Check" in
"Meter Check of Loads and Fuses"
section.
Unplug dishwasher or disconnect

1. Unplug dishwasher or disconnect
power and replace control.
2. Inspect diverter motor and
connections for overheating/
shorting. If evidence of overheating/
shorting exists, replace.
Remove lower spray arm, turbo
zone assembly, rear feed tube, and
outlet cover. Verify the round
diverter disk is installed.
Unplug dishwasher or disconnect
power and check resistances of
dispenser solenoid and all
connections in the Dispenser
circuit. Fix/replace open
connection/part.
Refer to "Fuse Service Check" in
"Meter Check of Loads and Fuses"
section.
Unplug dishwasher or disconnect
power and replace control.
