Would a UI board also need a software update? I've tried 3 new control boards and each has had a steady green light (Software Error) right out of the box. UI doesn't work at all. GE dishwasher GDF620HGJ4BB and new control board WD21X24900.
Appreciate the reply. I was getting ready to box up the third machine control board to return and then scrap the dishwasher, but just to be sure I put power to it again and it started working. Very confusing, but I won't look a gift horse in the mouth. Now, however the dishwasher user interface activates every once and a while without prompting. Is this an indication of an issue or can I turn this feature off so it only comes on when I'm ready to start it?
