The door switch on my model was replaced under warranty, then the control board, under warranty as well, it went out again, but this time warranty was up, I replaced it and noticed that one of the plugs were melting, it worked for about a week, and went out again, now I have replaced the circuit board and complete harness because of the melted plugs and still the unit won't start with the start button, I can do the diagnostic modes, but that doesn't wash my dishes. Any help would be greatly appreciated, this dishwasher it only a year and a half old.

Answer Hello Jim. You need to test the door switches on the unit. If they are bad, they will cause the issue you are having with the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Answer Hank, sounds as if the ribbon cable is shorting and needs to be replaced. It only comes available with the control panel, part number is W10356466. Thanks!
Unit wouldn't start, but had panel lights. Then I removed and reinstalled door latch, result = no panel lights at all. I checked the bimetal fuse, it passes a voltage. I checked the power cord and connections seems ok. So I put in new control board and door latch, still no panel light. Suggestions?

Answer Hi. Use a volt/ohm meter part # TJMA-DM1 to assist you in your diagnostics. Find the supplied tech sheet behind the lower kick plate or under the control board. The hot wire from the junction box is black. It goes up to the door switch. Once the door is closed the switch sends it to the non-resettable thermal fuse part # W10258275 then to the L1 terminal tab on the control panel on the black wire with the white stripe. Verify voltage at the board at this point P6 and at the P2 connection that has the white w/blue wire. If there is no power there then replace the thermal fuse. Thank You.
Heated dry light and button stays on. Tried to take out of lock mode but unsuccessful. Now lights in middle that show clean,dry, wash are out and wash light blinks.

Answer Tom, The more likely issue is a control panel keypad circuit(s) failure "PROBLEM: Won’t Run and LED Above Key(s) is Flashing Rapidly - Short circuit(s) in keypad or in control’s input lines that read the keys. - " The control panel [AP5176683} is the more likely issue. You can remove the lower kickplate access panel, you should find the technical data sheet attached to the backside of the panel or the frame, you can conduct the diagnostic / reset test, and keypad test procedure to varify the issue.
