Abstract

A control circuit is disclosed for appliances such as dishwashers and clothes washers employing a microprocessor programmed to respond to user selected options to determine the operating sequence of the appliance. The control circuit includes a manually operable switch which when actuated generates a reset signal which interrupts or cancels appliance operation by resetting the microprocessor and additionally generates an initiating signal which when detected by the microprocessor following reset, causes the microprocessor to initiate a drain cycle to remove any water present in the appliance as part of the reset program routine.
