How to replace Washer Electronic Control Board. Once top of washer is removed, there is a troubleshooting guide taped to the underside of the washer top. It verified the problem was the CCU (electronic control board). Before removing old CCU, have a plan for labeling the connecting wires; with tape & marker and a sketched diagram, because nothing is labeled and there are many wires. You need to slide the old CCU about 1 inch to the right in order to remove it. Looking at the new one will give you an idea of how the tabs fit into the washer unit. 58 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
