Dan J. for Model Number GE Appliances Model GDT655SSJ2SS Hello, My dishwasher Model # GDT655SSJ2SS worked intermittently after a Power surge/Outage during a storm. I could cycle the breaker and it would work again. Then the UI on top of the door became unresponsive. It has 120vac at the receptacle. After reading the Q & A here it seemed I needed to replace the Main Control Board. I ordered and replaced the Main Control Board with no success. How do I check the wiring harness and/or UI Board? What else could it be?
Answer Dan, You would want to check for 13 VDC getting to the UI board at the connector J401 pin 1 to pin 2. If there is 13 vdc then this will be a faulty UI board. If there is not then go to the main board J722 and test pin 2 to pin 5 and if there is voltage then the harness will be faulty, no voltage would be a faulty main board. Read More...
