No power

Make sure the dishwasher is getting power first. If so, remove the kick panel below the door and look for the 3″ x 3″ sheet metal box. Remove the cover and you can see the junction box wire connections to the dishwasher. These wires will often short out, melt, or get loose. Check all the connections and if they are faulty or burnt, cut the wires back and re-wire the junction box (with the power disconnected to the dishwasher of course). If everything checks good–you’ll need to order and replace the control board in the upper right hand corner of the door.
