Nancy T Bensalem , PA November 18, 2018 Appliance: Maytag Undercounter Dishwasher MDBH965AWB40 Maytag Dishwasher Mdbh965awb40: Error code 9 flashing dw would not work. How to replace Panel- Con. Ordered the control panel with the help of wonderful customer service on the phone. It literally took us 20 minutes to remove the old one and install the new one. Most of the time was removing and replacing screws, which you will need T20 Torx driver and a Hex Driver to do. I'm 65 and my husband is 76 and it took us no time at all to get this done thanks to everyone's comments here. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
