Michael M Dunkirk , NY August 28, 2014 Appliance: Maytag Portable Dishwasher MDC4650AWW0 Maytag Dishwasher Mdc4650aww0: Control board not working. How to replace Panel- Con. The power light to the control panel was lit. However none of the function buttons would work. Since it was still getting power, I figured it must be the control panel that needed replacing. Sure enough, that was the problem. Very easy to fix. Took about 15 minutes. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
