James L Amherst , WI February 26, 2017 Appliance: Whirlpool Undercounter Dishwasher WDF510PAYW6 Whirlpool Dishwasher Wdf510payw6: Not drying dishes. How to replace Dishwasher Heating Element. I replaced the heating element. I was able to remove the plastic retaining nuts that hold the element with just my hands. I only hand tightened them after putting the new heating element as well. I then ran a diagnostic cycle and the dishwasher is back to being great again. Thanks so much! 133 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
