Melissa B Slaughter , LA June 12, 2016 Appliance: Maytag Undercounter Dishwasher MDBH985AWW41 Maytag Dishwasher Mdbh985aww41: Dishwasher on/off button not working. How to replace Control Panel. I Googled what could be causing the problem and determined that it was the control panel that needed to be replaced. I also watched a YouTube video on how to replace it and realized it was a simple repair that I could do myself. I live chatted with an Appliance Parts Pro agent to ensure I ordered the correct part. It took a drill and a little help from my son to hold the door down, but took about 10 minutes max to replace. Easy peezy! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
