Dishwasher Door Gasket - Gray WPW10509257

Installed new door seal. Dishwasher still leaked. Googled the model number and then cleaned the filter at the bottom of the dishwasher, still leaked.
Verified that manifold bearing was not work. It was OK.
Found note that a plugged vent might cause leaking door. Very counterintuitive. Pried off air vent cover. Vent was thouroughly plugged with calcium deposts from steam. Cleaned these out.
Dishwasher no longer leaks.

I removed the old gasket, installed the new one which took about 20 seconds.Tested the unit, water was still dripping, but in a different fashion.As per a previous poster's instructions I removed the vent cover. (Located inside the dishwasher up high.)I cleaned out the calcium deposits with hot water and a sacraficial toothbrush. "Ta-Da!" Everything is now groovy!Thank you so very much for your excellent service. Your site was easy to use and your shipping was "lightning fast!" Also, the advice you sent me was invaluable. I thank you, my wife thanks you and my trained lobster thanks you too! :)

This repair was very simple. I opened the door of the dishwasher then pulled the old rubber seal (gasket) out; I checked the old gasket to with the new one to ensure the new one was correct then installed the new one. There are two small rubber pieces located in mounting slots below the door gasket that slide out; I slide the old ones out and slide the new ones in. No tools required.
The thing that made the whole job easier was ordering the parts from Parts Select; I couldn't find exactly what I needed on the Whirlpool website but I found exactly what I needed on the Parts Select website and the parts were a perfect match.

removed old parts and re-installed new parts. The spring is a little hard to get to the right point without a jewelers screwdriver, after that everything worked fine.

The gasket was a breeze, with just pulling out the old one and slowly pushing in the new in the track with my fingers. The shield was a little harder since there was no instructions before me. It turns out that it fits in the inner door and is used as a baffel for the steam (another problem with leaking out the bottom). After removing the front cosmetic pannel you need to thread the shield inside on three tabs that hold it. It took a few times to orientate it properly but it snaps in when correct. After the front pannel was put on and the unit test operated, the washer no longer leaks. Highly recommend the parts and help from PartSelect and the others before me.

After hearing ominous grinding sounds and water leaking around the gasket, it was about time to rehab the dishwasher. This is usually the point where I say "t'hell with it, buy a new one". I am glad I didn't.
The Kit to rehab the impeller and such had EVERYTHING I needed. Right parts, right price.
Removed the upper arm assembly, T15 screwdriver, the screen strainer, the impeller, T25 screwdriver, the food grinding spring and impeller (the grinding noise, spring was sprung), and finally the post and impeller thingie (had to break it off, very brittle). The pieces went back on a lot more smoothly than it took to get them off!
Use your digital camera! I took pictures of every stage of the parts removal and what I removed. I got confused with some little balls that were inside and the pictures told me exactly where they went.
Door gasket? I should have replaced it YEARS ago, so easy and cheap with PartSelect parts.

Since I had never made a repair on this 14 year old Kitchen Aid dishwasher, it was "discover as you go." First turned it on its back, took off bottom, disconnected both hoses and found out that hoses would not move. So, had to take off top and remove the back/side unit to get to hoses on top side where they were fastened by tape and a hose holder. Replaced hoses, used old clamp and "buttoned" it up.

The old gasket came out easily, but had calcium deposits in area. I cleaned the area with vinegar and water and waited until it was completely dry. The new gasket went in very easily and looked great. I started the dishwasher and alas, it still leaks, so the problem was apparently not with the gasket, but some other area. But the gasket is nice and new. Any suggestions on next step0 in troubleshooting?

Simply removed deflectors and gasket, replaced all , took all of 5 mins. workes great now.

first i picked out the old seal, use a screwdriver to get it started. Then I pushed the new one in after cleaning the seal channel. I fixed it during a commercial while watching my favorite tv show.
