Kathryn S Webster , NY April 22, 2015 Appliance: Frigidaire Dishwasher GLD2440REB1 Frigidaire Dishwasher Gld2440reb1: Middle sprayer (under top rack) broke off and needed to be replaced. How to replace Upper Rack Assembly. I chatted with a rep to make sure that I was getting the correct part. I found out that you can't just order the sprayer part, you have to order the top rack as well. I watched a video on how to remove the end caps for the wheel tracks so I could take the drawer out. I decided to use the new drawer (although my old one was still okay). I was able to attach the new sprayer by using my old rack as a guide. Attaching the wheels to the rack were an issue. I didn't have the same kind on my old rack and there was no video on how to do this that I could find. You have to make sure that the wheels put the rack in the right place so that the sprayer lines up with the water supply hole on the back wall of the dishwasher. The wheels snap very tightly into place on the rack. If they don't, then they may fall off, as they did during one of my attempts to attach them to the rack. It would have been helpful and saved some time to have had a video to show how to attach these wheels. Overall it wasn't a difficult repair. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
