COMMON PROBLEMS

REMEDY
Change operation mode from MANUAL to AUTO position.
During the wash cycle, the cam timer will move for the first 30 seconds
of the wash cycle. The cycle delay timer will then cause the cam timer to
stop in order to increase the length of the wash cycle. The red light on
the delay timer is in control of the cam timer. If the red light is not turning
on (only during cycles B, C, or D), replace the cycle timer.
If the wash cycle delay timer and rotating cam timer are working correctly,
the time cycles on the delay timer might be incorrectly adjusted. Adjust
the delay potentiometer corresponding to the B, C, or D cycle. Rerun
the appropriate cycle and see if the adjustment made any change in the
length of the cycle. If not, replace the cycle delay timer.
Confirm that the wash cycle delay timer is functioning correctly (see
above). Confirm that the timer motor is receiving power. If it is, replace
the motor and/or timer assembly. Make sure there are no obstructions
which limit the rotation of the cam timer.
Repair or replace valve as required.
Verify the wiring of the switch; if correct, replace the switch.
Clean probe if fouled. If clean and not working, replace.
Reset. If the breaker trips again, contact an electrician to verify the amp
draw of the machine.

source.
Verify the wiring of the switch; if correct, replace switch.
