Thomas C Albuquerque , NM March 28, 2022 Appliance: Model PDT740SSF1SS My user interface board had gone bad. Got a new UI board and silicon pipe (the overlay that protects the UI board and has the rubber nodes that the plastic control buttons fit on) and voilà it worked. I should say that I forgot to adjust the jumpers on the UI board appropriately for my model dishwasher so I had to open it back up to make it work. We’re back in business. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
