Kerry H Bloomfield , MI September 21, 2014 Appliance: Maytag Undercounter Dishwasher MDB7749SBW0 Maytag Dishwasher Mdb7749sbw0 / : Touch controls panel. How to replace Panel-Cntl (Wht). I ordered a new one based on all the comments about the same problem others where having. I guess they do not last long. Whirlpool should sell them by the 6 pack I guess as I am sure it will fail again. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
