A:Answer From my experience, and after researching online, it is the connector box supplied with your purchase. Mine dishwasher kept shutting frequently for about 4 month until last night 11/10/21, the connector box caught fire and shut my dishwasher down. Please do not wait, get that off your dishwasher. See for yourself, this is what happened to me and others.
