John V Melbourne , FL December 18, 2018 “Heavy duty” and “normal wash” lights flashing alternating control switches ineffective Reviewed symptoms on line. The majority opinion was that the control panel was the problem. In fact many of the switches felt “soft” and like they weren’t making contact. Ordered a new control panel. It arrived in two days and I installed it within 15 minutes. Works great now. You need a torx screwdriver Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
