Customer Questions and Answers for Dishwasher Main Control Board Assembly by Ge

Chuck, you're on the right track. It is more likely to have an intermittent or failed drain pump WD26X10039 than a defective control board WD21X10463 or wiring at this stage. You do want to make sure the filter screens and sump chamber are clear of any sediment, chemical build up or debris. You also may want to disconnect the drain hose from the plumbing, and drain the dishwasher into a bucket, a few times, this would clear any debris from the drain hose.
