How to Troubleshoot & Replace Bosch AP4434739 / 00676960 Dishwasher Control Board

Ordered a new control board and installed it after watching YouTube video. Simple and quick to install. And our order shipped quickly and packed very well to prevent damage. Very impressed with the service we received. 

Ruled out everything(sensors, heating element, hot water supply) and concluded it was the control board. Ordered it from AppliancePartsPros.com followed an online video and fixed it in less than 30 minutes. 

Website video showed perfectly how to remove and replace old Control Board.. 1st cycle with the new control showed various "E" and "H" codes, flashing indicator lights, and unresponsive buttons. Letting it "finish" (15 or 20? minutes), I opened the door, saw nothing had happened, reclosed the door, turned it off, waited a few seconds, turned it back on and it ran normally. 

Followed your excellent step by step video instructions. Wow, they were perfect and allowed me to follow along as I took apart the dishwasher, removed the old part and install the new one I ordered from you. Reassembeld the diswasher, started it, and it now performs like new! I receive the part within two day, Excellent customer service! 

Removed and replaced the control board using the Appliance Parts video. 

We replaced the control board with a video from Appliance Pros. The dishwasher works fine now. 

After doing a few minutes of research online, I suspected that the Bosch dishwasher was running a very extended period, due to it not sensing that the water was reaching a minimum temperature. The likely cause was a bad control board. After ordering this replacement part, I watch a tutorial video, on the installation. Repair took about 30 minutes, and the dishwasher is working like it should. Further inspection of the old control board showed that the relay controlling the heating element, had failed. 

Read several appliance repair forums and determined it was the control board. 

I diagnosed the problem as the Control Board. I used the Appliance Parts Pro system to find the right Control Board for my brand and model and ordered a new one. It arrived in a couple days. I watched the video provided by the Appliance Parts Pros website. My Bosch dishwasher was exactly the same as the Video. The new Control Board matched the old one perfectly and the replacement process went smoothly. The new Control Board worked fine and the dishwasher does all the proper functions now - all the cycles work just like it was a new machine. Later, I took the old Control Board apart and found a burned area on the circuit board - apparently the power failure and restart caused a surge that fried the board and melted the solder in one spot. 

I am now an official repair man. After checking other possibilies, I narrowed the problem to the control board. Appliancepartspros were able to match the right unit with my Bosch model at a great price. The video they provided made the repair a simple task. All is well again! Thanks Appliancepartspros, JKF
