ABSTRACT:
A control circuit is disclosed for appliances such as dishwashers and clothes washers. The control circuit employs a microprocessor programmed to respond to user selected options to determine the operating sequence of the appliance. The circuit includes a drain feedback system which permits the microprocessor to detect and identify a plurality of drain fault conditions including failure to drain, slow drain and plugged drain. A protective response is initiated by the microprocessor to prevent flooding or damage to the appliance should any of these fault conditions occur, and the user is advised of the specific fault mode via an alpha-numeric digital display on the appliance control panel. In the event a rapid drain occurs, the feedback system immediately terminates pump-out and transfers the time saved to a subsequent time-insensitive cycle, thereby eliminating undesirable operation of pump and motor while maintaining the total cycle time as originally programmed.
