Mike D Chicago , IL December 20, 2021 No LED service light on control panel and 3 beebs every time we tried to start a cycle. Reading posts from others with the same problem, it was clear the control panel was defective. We ordered the recommended replacement, installed it in 10 minutes and it fixed the problem. The dishwasher is back to full working order Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
