Raghu S San Ramon , CA October 22, 2014 Appliance: General Electric Dishwasher PDW7880J03SS Ge Dishwasher Pdw7880j03ss: Dishes were too cloudy and had some sort of deposit on them. How to replace Center Wash Arm Assembly. I have to appreciate the detailed stories/tips/steps on how to replace appliance parts on this site. I had replaced the lower spray arm earlier. This time, I ordered the Upper and Middle spray arms. I replaced both of them. Since I replaced them, the dishes are much cleaner than they were before. I also cleaned the filter below and cleaned up the gunk. Hope this fixes the problem for some time. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
