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. Feedback systems permit the detection and indication of fault conditions, such as overfill or drain blockage, and initiate protective responses from the microprocessor to prevent flooding or damage to the appliance. The circuit includes a diagnostic system having a diagnostic routine which will sequence through the usual operating cycles in response to operator input and which may be advanced through the cycles at the operator's discretion. The operative cycles and applicance malfunctions, if any, are displayed on a control panel as the diagnostic routine is executed thereby facilitating diagnosis and repair.
