PROBLEM

POSSIBLE CAUSE

SOLUTION

Overfills

Operating Pressure Switch fail-

Check Operating Pressure Switch con-

 

ure.

tact and wiring harness connections.

 

 

 

 

Pressure Switch tube off at

Check Pressure Switch tubing for proper

 

Pressure Switch or tub pressure

connection and check for kinks along

 

dome or kink in tubing.

length of tubing.

 

Not draining.

Check pump/drain system. Overfilling

 

 

could indicate a failure to drain.

 

 

 

Won’t Nutate

Machine or motor controller con-

Check all harness connectors and wir-

 

nections loose.

ing terminals.

 

 

 

 

Drive motor inoperative.

Check Drive motor windings for conti-

 

 

nuity. Check Drive motor for binding.

 

 

 

 

Drive belt broken.

Check drive belt. Replace as needed.

 

 

 

 

Drive mechanism failure.

Check drive pulley, nutate shaft, leveller,

 

 

inner wash plate and universal joint.

 

 

 

Won’t Spin

Machine or motor controller con-

Check all harness connectors and wir-

 

nections loose.

ing terminals.

 

 

 

 

Drive motor inoperative.

Check Drive motor windings for conti-

 

 

nuity. Check Drive motor for binding.

 

Drive belt broken.

Check drive belt. Replace as needed.

 

 

 

 

Drive mechanism failure.

Check drive pulley, basket drive brake

 

 

release pawl, spin tube and basket drive

 

 

block.

 

 

 

Motor Overheats

Drive Motor failure.

Check Drive motor windings for proper

 

 

resistances. Check wiring connectors.

 

 

 

 

Mechanical binding.

Check for free movement of drive

 

 

mechanism.

 

 

 

 

Inadequate voltage supply.

Do not use an extension cord. Check

 

 

for 120 VAC at outlet. If voltage drops

 

 

when washer is started, contact electri-

 

 

cian.

 

 

 

Tripping GFI

Shield Capacitor Shorted.

Check Shield Capacitor. If shorted, re-

 

 

place lower wiring harness.

 

 

 

 

Interlock Switch(es) shorted.

Check continuity of front and lower cabi-

 

 

net interlock switches. Switches are

 

 

normally closed and should show an

 

 

open circuit with cabinet panels in place.
