How to Troubleshoot & Replace Whirlpool AP6014951 / WPW10084142 Dishwasher Control Board

I initially purchased a door switch, thinking that it would solve the problem. I replaced the switch by removing the top 6 star screws, removing the component cover and removing one of the door switches (using a 3/16 socket) with the new one that I bought but I still had the problem. Looking at the schematic, the next part that needed to be changed is the electronic control board, which I purchased. I removed the same screws again and cover, used a screwdriver to pull back the clips holding the board, removed the connections one-by-one from the old board and reconnected them to the new board. Put everything back together, tested it and now it works like new. 

Unplugged the dishwasher. Took the front panel off the dishwasher, unclipped the wires and removed the old control and put the new one in. (we did mark some of the clips so we knew which side they went on). Put back together and plugged it back in. Easy!! AND the dishwasher works again!!!! Just in time for the holidays!!!! Thank you so much for your help and saving a "repair man call". 

We ordered a new control board for the dishwasher. The swap out was very easy. I just watched a youtube video showing how to do it. All it took was a screwdriver to take the front plate off. 

Ordered new board. 

Replaced both items. Easy fix. 

Did a factory reset (press normal, heat dry, normal, heat dry, normal) and a diagnostic self test (high temp, air dry, high temp, air dry), but nothing solved the problem. I had read this is a common problem problem and it was a bad control board. Our dishwasher was 4 years old, but seeing as this is a vacation home, it probably only had about 3 months total use. Turn off the power at the breaker, remove the top six screws (torx), pull off the control panel. Lift the three tabs that hold the cover on the inside of the panel, unplug the surface connections by pressing the tabs and pulling. Release the tabs holding the left edge of the board and rotate the board up. Release the edge connectors (tabs again). Remove the cancel/drain button. Reverse the order and your finished. Be sure you discharge and static from yourself by touching any metal part of the dishwasher often (its grounded) and handle the circuit board by the edge. Although probably not necessary, I performed the factory reset after replacing the board). 

Got a new control panel from you guys...Arrived in two days, it was fixed in 5 minutes!! Happy wife, Happy life. Thanks 

My Whirlpool Quiet Partner I [DU1055SXTSS3] dishwasher would fill with water, get stuck in the first part of the wash cycle, and then I could press cancel to have it drain the water. Washing the dishes was not happening. I suspected that the Electronic Control Board had gone bad. After removing the torx screws that secure the control panel, I opened the protective cover over the electronic control board to access it. I carefully unplugged all wire connection to the control board, carefully pulled it out, and reattached everything to the new control board. The dishwasher works now! 

I Googled the issue and found several articles claiming that the Control Module was the issue. Even reviews on this site make the same claim. The control module showed up in a few day and it took me all of about 10 minutes to swap the part. I used a torx bit to remove 6 screws, then the cover snaps off and the module comes out easily and the various electrical connectors are easy to remove. When putting it back together, don't forget the module cover like I did. :) So far the dishwasher is running perfectly, so the shutoff issue appears to be resolved. 

I repaired this dishwasher in less then 30 mins, with the help of my 9 year old son. He actually did almost all of the work. Together we replace the Control panel. My son removed the 6 screws holding the panel on the door, then removed the latch mechanism, then the electronic control cover (this required a little help from me), the I removed the electronic control. Reinstalled in the opposite order. My son needed a little help getting the parts properly aligned. Over all this is a repair anyone can do. I use the form here for troubleshooting help.
