Whirlpool WP8539324 Dishwasher Upper Spray Arm Mount OEM Part

I identified the parts I would need online, shopped for price and delivery, and ordered what I needed. I bought the support arm mount assembly and decided to replace the spray arm and tube as well. Installation was straightforward, although it took me a couple of tries to get the spray arm mount oriented correctly because it is angled to allow the spray arm to miss the deeper glasses channel on one side of the upper rack in the dishwasher. After clipping the arm support and the tube support in place, I installed the arm and tube and was finished.

It's an easy fix if you can find the right part. That's where AppliancePartsPros.com comes in. I input the model number and did a quick scan of the parts list. I found the part I needed, ordered it, and two days later I repaired the dishwasher.

I ordered the replacement Spray arm and mount, received them Saturday ahead of schedule, and had them installed and working within 5 minutes. The one thing I did different than in the video, because I was replacing both parts, is to attach the supply tube and spray arm to the mount assembly before clipping the mount assembly into the rack. The screw fits very tight the first time, and it would have been much more difficult to screw it in with the mount in place. I highly recommend replacing the mount assembly when replacing the spray arm and supply tube. If the arm or tube is brittle, so will the mount probably be. Mine broke with very little force, so I'm glad I had already ordered a replacement.

Replaced the Upper Spray Arm Assembly! Very easy to get part.

Removed and replaced. It would have been helpful if you would have included the screw since mine has the Phillips head rather than the one described in the video. It is hard to tighten the Phillips since it tends to strip. It was also difficult to know if it was tightened enough since it seemed rather floppy.
