Last week the dishwasher just quit working. No lights on the front panel, everything just seems dead. 
So far I have done the following and still the same result:
Checked breaker, its on.
Checked to see that it has power to the unit (behind toe panel).
Cleaned the contacts on the ribbon cable (didn’t really look dirty but did it anyway).
Replaced circuit board.
Replaced the door latch assembly.
I’m guessing I’m looking at having to replace the control panel but I’m looking for some input before I throw more time and money at this thing. :mad:
Here’s a couple video’s to help. Did you check to see if you had 120v to your main board? Did you check to see if the thermal fuse is blown?

Yes there is 120v going to the main board. I do not see any thermal fuse on my model like in the video and i do not see any referenced in the parts list. I did dig into it a bit further today and actually removed and inspected the control panel/touch panel. There does seem to be some corrosion where the cable passes through towards the front side. Also peeled off the outer layer of the panel and see some corroded spots along the pathways. My guess is this is the culprit after all.
