Upper Dishrack W10727422

Just had to transfer all the kit parts from the old rack to the new one.
It was important to leave one side of the kit parts(the wheel and other plastic pieces) on the old one while transferring the other side of the kit parts to the new rack so that I had a visual reference for placement and orientation of the parts on the new rack.

I removed the upper dishwasher rack and disassembled the middle spray arm as described in other posts. Replacement was easy. The difficult part was to figure out what was causing my dishwasher to leak. I had seen many references on line to leaks being caused by the door seal or lower vent wear. I had replaced both. Those replacements resulted in less leaking, but I still had water coming out. There were also references to leaks sometimes being caused when the lower spray arm was cracked, but mine was fine. (My dishwasher has an aluminum lower arm, so it wouldn't crack.) I discovered the middle spray arm was cracked when replacing the upper dish rack. (It was starting to rust.) Apparently, when the middle spray arm is cracked, the heavier circular water flow from it creates a wave motion (vortex) in the bottom of the dishwasher. That pushes water past the seals at the bottom of the door. Once I replaced the middle spray arm the water leak problem disappeared. As an added bonus, my glasses came out cleaner! I have never seen a post indicating that a cracked middle spray arm could lead to water leakage, so hopefully this post solves someone else's mystery problem!

The rack itself is rather easy to pull out, pop out the tabs and the rack will slide out. Once you get it out, its a bit more challenging as the rack itself needs to be disassembled. Don't waste a lot of time removing the rails - cut the tines on the old rack and take those off. Unscrew the back of the panel holding the adjustment assembly and the item will come off more quickly. All the rest of this is simple and can be disassembled and snapped back together by hand.

My KitchenAid dishwasher's upper dishrack had several places that were completing rusting out, just leaving the skins of the plastic coating in place. I ordered the upper dishrack - just the dishrack, none of the clips or other items shown in the schematic - and installed it pretty easily. One caution - this is JUST the upper dishrack. If you have two rows of tines that are clipped in and flip-flop back and forth on the left and right wider sides of the rack, you will need to order one or two pieces of part # PS 898500 as well. One of my tine rows was in salvageable shape, so I only needed to order one (in a second order upon discovering I it wasn't included). It wasn't difficult to figure out how the clips could come out and snap back in place. Just be careful, know that these are just plastic items and can break easily.

It was easy! First I ordered the expensive replacement parts on line. The parts arrived in one week. I was able to slide the old drawers out, slip a few parts off of the old drawers, snap them on and slide the new drawers in place!
