The latch mechanism includes a first portion on the access door and a second portion on the cabinet which cooperate to lock the access door in the closed position at predetermined times in a cycle of operations. The second portion of the latch mechanism is controlled through a bimetal actuator which is heated by a low voltage current inductively generated in an auxiliary winding associated with a pump motor.
