If motor does not run;
•
Check for 120 VAC at the motor control board har-
ness.
See Figure 1.
If voltage is present,
then problem lies with the
motor and motor control system.
•
Check for loose electrical connections at mo-
tor and motor control board.
•
Check phase windings of the motor.
See Fig-
ure 2.
If motor windings are good, replace the
motor control board.
If voltage is not present;
•
Check loose electrical connections at machine
control board or broken wires in harness.
•
Check door actuator switch and related wiring.
Door Lock Test
Placing the washer into the Service Mode and
manually locking and unlocking the
door mechanism through the control panel can
verify the door lock.
Note:
The relay on the control
board for the door unlock mechanism is disabled if
the motor control board indicates the spinner speed
is > 7 RPM.
1. Place the washer into Service Mode. (See
Service Mode)
2. Advance to the Board Output Test and press
max extract
to
lock the door
. A lock signal
will be sent to the solenoid every second for 10
seconds. If the door does not lock; use a
voltmeter, look for 120VAC, 60 millisecond
pulse to the locking solenoid.
7. Press
stain cycle
to start the motor control
output test. This will send 120VAC to the motor
control board. The motor control will immediately
execute a test routine and the motor should run,
rotating the spinner at 50 rpm.
3.
If signal is present
, then the door lock sole-
noid is bad and the door lock mechanism must
be replaced. (Assuming the door was fully
closed.) To stop the signal, press
max extract
again.
4.
If signal is not present,
check electrical
connections at switch or at control board.
Check for proper outputs from the control board
at Conn P1(1) and Neutral leg of power cord. If
voltage is present, fix electrical connections or
change wire harness. If no voltage is found, go
to P8(4) and Neutral on power cord to verify
120VAC coming into the board. If voltage is not
present check the door actuator switch. (make
sure door is closed.) If voltage is present,
change machine control board.
5. Access
Board Output Test
by touching the
rinse
key to activate.
6. The door must be locked to access
Motor Con-
trol Board Output Test.
To lock the door press
max extract
. Press
max extract
again stop the
door lock output test once the door is locked.
!
WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect power to washer before servicing,
unless testing requires it.
