1. With the machine powered up, closing the doors begins a cycle.

a) When the door closes the timer assembly motor is energized through the normally

closed contact of the Start/Stop Relay.

b) Within a couple of seconds cams 1 and 2 close their respective switches. Cam

switch 1 (Start/Stop) maintains power to the timer assembly motor throughout the
90-second cycle. Cam switch 2 (Cycle Reset) energizes the Start/Stop Relay.

c) The Start/Stop Relay, once it is energized by cam switch 2, is held in by its own

normally open contact for as long as the doors remain closed.

2. Cam switch 8 controls the pump motor. The pump motor comes ON at the beginning
of the operational cycle and continues to run until the end of the drain function
(controlled by cam switch 3), at which time it turns off for about eight seconds allowing
time for the machine to refill enough to avoid running the pump dry before the pump
motor restarts and runs to the completion of the operational cycle.
