Error codeF4E3

F4E3 sets out two possibilities on a Maytag dishwasher: a heater relay that has shorted, or a heater that has failed.
What stays with the technician
The manual lists no steps for owners here. Begin by taking the dishwasher off power; the heater and relay themselves are for a technician to handle.
