Sheri B Cincinnati , OH September 19, 2014 Appliance: Model MAYTAG QUIET WASH 300 (MDB670AWB) First the numbers on the diswasher's control panel were garbled then some of the buttons would not work and finally none of the buttons worked and the dishwasher would not function I checked all the electrical connections to make sure the control panel was receiving power. Once I confirmed the electrical was working, I ordered a replacement control panel from AppliancePartsPros. It arrived in just two days and was a cinch to install. The dishwasher was working 15 minutes after the part arrived. I highly recommend AppliancePartsPros.com! 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
