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 control circuit includes an overfill system which permits the microprocessor to detect and identify a flood condition in response to a signal from a float assembly. The flood signal causes the microprocessor to initiate a flood control routine which interrupts the normal operating cycle being executed, if any, and initiates and maintains operation of a drain cycle until the water returns to the normal level for a predetermined period of time. The flood routine overrides all other program control thereby preventing any other machine function until the flood condition has been eliminated and there has been user interaction. The user is advised of the flood condition via an alpha-numeric digital display on the appliance control panel. The overfill system will be activated regardless of the operative state of the appliance.
