CHECKOUT

NOTE:
All electrical checks should be made by qualified service personnel.
If it's determined that the proper power is being applied to the machine's incoming terminal blocks, then
further check of the safety switch should be made. NOTE: THIS CHECKOUT WOULD ONLY BE PER¬
FORMED IF NONE OF THE SYSTEMS OF THE MACHINE OPERATE. THIS WOULD MEAN THAT
NONE OF THE SWITCHES, WHEN DEPRESSED, WILL PERFORM THE FUNCTION NOTED FOR THAT
SWITCH.
Example: Drain, fill, start or manual wash switches.
Proceed with checkout.
1. Remove power to the machine by turning circuit breaker that protects the machine

2. Open the front door and remove screws holding inside panel of door.
3. Disconnect one wire from the switch closest to the door latch and using an ohmmeter,
depress the lever of the switch and check that there is continuity across that switch.

one side of the switch and check for continuity with ohmmeter when switch is depressed.
