摘要： An electrical circuit for controlling various functions in a plurality of dishwashers having common features of a washing chamber containing a quantity of washing solution, means for heating the washing solution, a temperature sensor arranged to respond to the temperature of the solution, a pump for circulating washing solution through a spray head, and an electric motor for driving the pump. The control circuit includes a plurality of circuit boards for controlling the sequence of operation of the dishwasher, overheating protection for the pump motor, and the means for heating the washing solution. Many circuit boards contain indicating lamps in the form of light emitting diodes to indicate proper operation of the circuit. Other circuit boards include optional features, such as automatic initiation of the washing cycle upon the closure of the door.
