Very low useage on dishwasher. Controls do not function except air dry and cancel. When I turn the power of for a period of time, all function returns and the dishwasher work as it should with full wash selection and options. After a complete wash and dry cycle the controls fail to function again until I remove power for a period of time and then full function again returns. If you don't use the dishwasher over a short period of time the functions again fail. If you selection and then cancel a cycle the controls fail. I believe it to be the control circuit, but just not quite sure. I have checked all other components with either a meter or removing them from the circuit. I am between the control board and the control panel. Any ideas.
