Our dishwasher thinks there is water in it when it's empty. It is turning itself on also. Disconnected drain hose from the garbage disposal and put water in the bottom of the dishwasher. Turned it on and kept feeding it water to try to change to the next cycle, no luck. Turned the circuit breaker off for 10 minutes. Tried the drain cancel, no luck. Was able to change cycles but pump kept on pumping. Help!
