Daniel H Williamsville , NY August 08, 2016 Appliance: Model GE PDW8000 SERIES Dishes weren't getting clean Replaced the lower and middle spray arm. It was very easy. Tools weren't necessary to remove the lower spay arm - I just followed the video you had on your site. The middle spay arm was removed with just a 1/4" nut driver. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
