• Check between tubs for something contacting spinner.
• Check for proper adjustment of the Thrust Bearing.
• Check for broken impeller on Drain Pump, washer
should drain all water within 90 seconds.
• When washer passes all checks place a one pound
unbalance weight in washer and check for 600 RPM. If
washer fails, check brake and cam adjustments.
Replace Transmission if brake and cam adjustments
are ok.
Motor Not Running
• Check power supply to washer is between 108V and
132V during a load on circuit.
• Check if Lid Switch is functional. Lid must be closed
before washer will operate.
• Check voltage going into, and out of timer to start and
run windings, per ladder diagram.
• Check for 120 volts to start and run winding at motor
per ladder diagram.
• Check for a blown motor thermal fuse.
• Check for obstructions in Drain Pump.
• Turn transmission pulley byhand. If locked in agitation
direction, replace transmission.
No Water Fill
• Check to make sure water supply is turned on fully.
• Check electrical circuit and connections at the Water
Valve, and Pressure Switch.
• Check for kinks in inlet hoses.
• Check for clogged inlet screens and water valve
screens.
• Check Water Valves separately for fill.
• Check for low water pressure. May be dependent on
pressure entering home. Variations may occur due to
usage in the home at the time machine is used.
• Check for frozen pipes and hoses.
• Check hot and cold water valve voltage for 120 volts.
• If washer fills and drains at the same time, check for
drain hose siphoning.
Will Not Drain
• Check for restricted drain system.
• In cold climates check for frozen drain hose.
• Check for broken impeller on Drain Pump. Washer
should drain all water within 90 seconds.
• Check motor slide and spring for proper movement.
