Section 3 Troubleshooting
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the washer before servicing.
• Never start the washer with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer is properly grounded.

Control System Faults
Shown below are the system faults that will cause control to shut down and sound the BUZZER continuously until
electrical power to washer is turned off.
Washer “DC” Motor Functions
Agitate
For agitate, the “DC” current will flow through the full
field (D1, D2) of motor. The washer agitation is
produced by reversing polarity of the rotor in motor.
This polarity switching takes place on control board.
One direction RL3 and RL4 are not operated.
The other direction RL3 and RL4 are operated.
Refer to wiring schematics on following pages.
Spin
For spin (0 - 650 rpm), the “DC” current will flow
through the full field (D1, D2) of motor. For high speed
spin (+ 650 rpm), the “DC” voltage will flow through
half the field (D1, D3) of motor.
Refer to wiring schematic on following pages.
INOPERATIVE CONDITION
SERVICE CORRECTION
Triac in motor control board shorted.
Change control board. Check motor.
Motor tachometer feedback signal circuit open.
Correct wiring between control board and motor.
Change motor.
Motor circuit fuse blown.
Change “FUS1” on control board and check washer
cylinder. Motor for mechanical binding.
Motor fails to spin up to correct speed in predetermined
time.
Check washer cylinder. Motor for mechanical binding.
Change motor.
Control door lock relay contact failure.
Refer to “Washer Will Not Start” (Door lock switch
analysis). Refer to paragraph 2
Washer tries to agitate for more than 40 minutes after
water level is attained.
Check wiring to timer. Check voltage at timer. Change
timer.
