Mehdi P Corona , CA October 26, 2014 When plug power in the dish washer just beep I thought the system module was the problem. I order that it did not fix it. I called your Tech support the same night and they helped me to order the Keypad. I got the Keypad and it fixed it. Thanks Mehdi 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
