Dale S Idaho Falls , ID November 23, 2016 Appliance: Maytag Undercounter Dishwasher MDB7749AWM2 Maytag Dishwasher Mdb7749awm2: Control panel buttons stopped working. How to replace Dishwasher Control Panel Touch Pad. Online there were lots of stories about flat plastic cable getting rusted. some were able to clean the cable and paint on new circuits, but the places where the rust was on my cable made it impossible. I had to replace the whole control panel because you can't just replace the cable. I replaced the old control panel with a new control panel. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
