Mother board defective

First diagnosed the problem by viewing several Youtube videos. Then ordered the part from AppliancePartsPros. After the part arrived I again referenced the best video - several times - and finally made the repair swapping out bad mother board with the new one from AppliancePartsPros. Saved me hundreds. Dishwasher works great, wife happy! All is good.

Ge profile dishwasher had h20 error code

It was one of 3 things basically, motherboard, pressure sensor or fill valve. I tried cleaning the pressure sensor to no avail. I proceeded to replace both the valve and the sensor because the parts were very inexpensive and the cost of a motherboard wasn't worth it. I completed the repair in about 1 hour and have ran it twice without incident .
