In my situation my display was turning on and off very rapidly and most of the buttons were unusable.
I took off the front door, unplugged and inspected the jackplug and wiring to the display board and didn’t find anything damaged.
I also didn’t find any moisture behind the silicone sealant.
After reconnecting the jackplug the dishwasher ran through a complete cycle. There may have been some corrosion or buildup on the jackplug that was dislodged when I removed it.
If the moisture claim is true it may be that this jackplug not being protected is the culprit. I’m hesitant to put any protection over the wiring harness though. As it would make removing it a pain in the ass.
