I opened the unit, the main board had a solid green light. Tested the voltage between 1 and 4 pins, which had about 12v. Replaced the UI board and the problem was resolved. The repair was moderate difficulty level. I had to pull the dishwasher unit out a few inches to access the hinges and remove the tensioners, to get the door off. Once the door was off, removed 2 bottom screws and the inner panel slides up to remove. UI board assembly was held in place by 4 screws. A small pick will be helpful to separate the display assembly. I set the jumpers and reassembled everything in reverse order. Everything is good to go!
