Mike W. for Model Number GDF540HGD0WW THE UI control board on my dishwasher does not light up and is unresponsive. I confirmed there is power to the appliance and ther is 30 volts at the main control board at the yellow/blue and black/green terminals. I replaced the UI control board and configured it with all 4 jumpers in place as outlined in the instructions. The UI control board still does not light up or respond. What else can be the issue? Was there supposed to be an updated wiring harness between the main and UI control boards?
Answer Mike, There is not an updated harness but would most likely be a faulty harness if you have proper power from the main board but the user interface is not lighting up. Read More... Answered by AppliancePartsPros.com | Wednesday, April 20, 2022
