Removing The Racks
Open the dishwasher door, then pull the bottom rack all the way out so that it rests on the dishwasher door, as if it were being loaded. Lift the rack out to remove.
Pull the top rack out of the dishwasher so that the arms are fully extended.
Remove the rack-stop on the end of each arm by pressing in the tabs on the inside of the rack-stop, then pulling off the rack-stop.
Pull the rack straight out of the arms and out of the dishwasher.
Replacing the Wheels
Remove the rack from the dishwasher.
Pull the old wheel bracket straight off of the rack.
Squeeze the two clips in the center of the outside of the wheel, then remove the wheel from the bracket.
Snap the new wheel onto the wheel bracket.
Insert the arm on the bottom of the dishwasher into the rear of the wheel bracket, then snap the bracket into place.
