Dennis L Chandler , AZ March 31, 2020 Appliance: KitchenAid Undercounter Dishwasher KUDP01FLSS6 Kitchenaid Dishwasher Kudp01flss6: Kitchenaid dishwasher had fault whee light blinked 7 times paused and repeated. How to replace Push On Retainer Nut. Fault indicated likely cause was a bad heating element. Ordered the heating element and had it 3 days later. I've worked on the dishwasher before and am mechanically inclined. So removal of the washer from the cabinet to gain full access to the machine was not new to me. This is not difficult - the video covers it very well. I found the replacement of the element straight forward and takes about 15 minutes to complete after gaining access. Again the video covers the replacement well. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
