Matt M Manchester , IA August 29, 2015 Appliance: Whirlpool Undercounter Dishwasher GU3200XTXY3 Whirlpool Dishwasher Gu3200xtxy3: Replace the control panel in a whirlpool dishwasher. How to replace Control Panel. Easy fix, just removed the front panel and took the control panel out. You have to be careful because there are some fragile parts connected to it. Unplug the wires, plug then into the new control panel and then put it all back together. Took me 10 minutes to complete the job. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
