How to Troubleshoot & Replace Ge AP7218675 / WD21X31900C Dishwasher Main Control Board

I ordered a new one. Watched a youtube video on how to access the board and replace it. 

Replaced the board. I had to replace the board and there was an excellent YouTube video that really helped, but omitted the personality (jumper pin) settings.... https://youtu.be/SnlGOBVZt1U 

Tested wire harness for continuity from the control board to circulation pump, tested okay. Removed connector from the circulation pump, and applied 120v directly to pump, pump works as designed. Tested power from control board in “test mode” no power output from the control board. Tested control board fuse, “open”… needs control board. R&R MC Board, retested okay… 

Replaced Master Control Board. Gave the repair rating a 2 because I’m older now. Just a little harder to get into different positions to affect the repair. The repair is definitely easy for the younger. 

Replaced the control board. Quick and easy.

Replaced the control. Your video saved us a lot of time. The hardest part was getting the tray back in. 

Went on Online and read the problems with the Machine. Ordered a new machine control board. Plus, a new water inlet valve.
