Wayne W Hoffman Estates , IL February 21, 2016 Appliance: Model GE DISHWASHER Top rack guide (wheels) where falling off I pulled the dishwasher out by removing screws that go into countertop. I then turned the adjustable screws on the front legs of the dishwasher enough to make sure I can slide the unit out. Slid the unit out a litte more than a foot. Moved the insulation off the sides saw the screws to put on the new guides removed the screws removed old guides put on new guides tighten screws and put the dishwasher back in place. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
