Abstract
An improved control circuit is provided for an automatic dishwasher having a reversing relay with valve arrangement which supplies cavitation air to the fluid distribution system to reduce the energy level at which the liquid is sprayed into the wash chamber to achieve a GENTLE wash and rinse cycle for fine china and crystal. The reversing relay solenoid armature operates, in conjunction with a start relay, to provide a primary function of reversing the direction of rotation of the motor between wash and drain periods while providing an auxiliary function of opening its associated valve to admit cavitation air to the recirculation pump during a GENTLE wash and rinse cycle and closing the valve during the REGULAR wash and rinse cycle.
