Matthew R Brooklyn , NY April 15, 2018 Appliance: Model GE GDWF160V40SS Top rotating spray arm and middle rotating arm had issues I replaced the upper spray arm bearing and screw, and also replaced the middle spray arm housing. The whole project was super easy -- except for the first part: removing the upper rack so I could move around it. My unit had these two gray clips (one on either side) within the inner rail area and they were hard to find. Once I found them, I just had to push on them to get the upper rack to come out so I could work on the two spray arms. The rest was easy. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
