Our dishwasher controls stop working - no lights showed. When we opened the door there was water in the bottom. There is power to the unit. When I removed the door and looked at the control board the larger black wire connector that runs parallel to the top of the door was burnt on one side where it plugs into the board (the board at the prongs was also burnt). The other black wire connector that is parallel to the door sides had the plastic insulation on the wires scorched about 1" from the connection. The connection itself was fine but the black pad on the inside face of the door shell was melted a little where the wires were touching it. Do you think I will have to replace both the board and the harns-wire? If the harns-wire needs to be replaced, do I need to disconnect and reconnect all those wires on each end? Also, what could be the cause for these connections overheating? Thanks for any help you can provide.
ANSWER Rich, There are several other things to check and replace as well. You can repair the harness, using connectors, terminals, and "shrink wrap" insulation. You will need to consider a new Control panel thermal fuse kit W10258275 and control board W10084141. You will also want to check and make sure that the wiring in the junction box on the dishwasher frame, behind the kickplate, is a good, solid, polarized and grounded connection and properly insulated, and taped over. That should get you back in operation. You should find your wiring diagram and Tech Data Information attached to the back of the kickplate or attached to the lower frame support.
