How to Troubleshoot & Replace Whirlpool AP3115182 / 675808 Spray Arm And Supply Tube Kit

Obtained a replacement spray arm and supply tube kit. Replaced the components in about 10 minutes. Works great! 

Took the old one off and followed directions and put the new on on. Very easy to do. Took longer to open the box than to replace the new part. 

Ordered the replacement kit, and received it the following day, and in less than 5 minutes had all the parts replaced, and the dishwasher working again. Extremely please with the delivery time, and availability to find the parts. 

Found the part very easily on this site. Arrived in 2 days. The replacement was EXACTLY like the video. One tip - the replacement comes with a Phillips screw to replace the 3/8 screw. The Phillips screw was so difficult to seat, I lagged it out and used the original 3/8 screw. Dishwasher looks like it cleaned itself after one run. 

Replaced it with new spray arm. 

Removed old spinner and feed tube by clipping of old feed tube and removing the screw. After doing so it was easy. I installed the new feed tube with the screw included in the kit, clipped on the spinner and was very easy. 

New part 

I replaced the entire spray arm and supply tube kit. I simply followed the video instructions. 

Replaced spray arm and supply tube 

Replace the upper spray arm and supply tube. When ordering this part I noticed that it was recommended that I also purchase a new mount assembly and was glad I did, the screw on the old one broke when I was trying to remove it (not surprised, the dishwasher is 22 year old). The videos were very helpful, confirmed something that I was confused about on the design of the upper mount. Overall very easy fix, great information from AppliancePartsPros in both recommending the additional part, and the how to fix videos.
