Touch and hold the “Control Lock” or the “4 Hour Delay” key pad (depending up on the KitchenAid dishwasher model) for four seconds to release the control lock feature.
Use a lightly dampened cloth to wipe the control panel and clean away any residue that might be causing one or more of the keypads to stick in place.
Open and close the dishwasher door firmly.
Disconnect power either through the power cord or by shutting off the circuit breaker. Wait five minutes and restore power.
