	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.
