Open the door to the GE dishwasher and allow it to lay down flat.
Pull the upper dish rack out as far as it will go.
Reach back and locate the clip-on tabs on the back ends of the track rails. GE dishwashers have either plastic or stainless steel clips.
Press the side of the tab in and slide the tab off the back of the track rail if you have a stainless steel clip. For a plastic clip, slide a flathead screwdriver or a quarter into the gap on the side of the clip and push it toward the back of the clip while pulling the clip out from the side. Repeat for the other track rail clip.
Pull the dish rack, along with both of the track rails, out of the dishwasher.
