John for Model Number GU1500XTLB2 My dishwasher stopped working a couple of weeks ago. Only the cancel function would work and I had no other lights other than the 2 and 1 on the display as the unit went through the cancel function. I replaced the control card #AP3775964 and the unit seemed to work OK again. After a couple of washes, I noted that it would only work on a couple of Sensing Wash Cycles ( china crystal and rinse only ) and then none at all. After pressing buttons repeatedly for a few minutes, eventually I got it to where "1H" was displayed. By pressing the cancel button a number of times eventually the display goes beyond "10", and then the unit will work on any sensing wash cycle. The next time you try to run the unit, it seems dead again. Only the cancel mode works. By pressing various buttons again repeatedly, you can eventually get it to work for the next wash. Any thoughts or suggestions would be appreciated. Thanks
Answer Hello John. Based on the information you provided, it sounds like the control panel WP8534839 is bad and will need to be replaced. If some of the buttons are non responsive, this is due to a bad control panel. Hope this helps. Read More... Answered by AppliancePartsPros.com | Wednesday, June 22, 2011
