Richard H Ann Arbor , MI July 13, 2015 Appliance: Maytag Undercounter Dishwasher MDBH989AWQ3 Maytag Dishwasher Mdbh989awq3: Wouldn't start. How to replace Control Panel. Most of the buttons on the control panel worked but the "start" button did nothing. Since this was the second time in 3 years the dish washer has had this problem I knew the control panel itself was the issue. Ordered the part and it arrived two days later. Pretty unhappy that this particular DW has cost me almost $300 in parts over the past 3 years, but being able to get the parts quickly thru AppliancePartsPro as well as their advice that led me to the control panel the first time is greatly appreciated. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
