DU900PCDB4 Whirlpool Dishwasher - Instructions

actually my wife did the repair. she unsrewed the water sprayer and removed it, then unscrewd the star key screws and then replaced the seal. she put everything back the way it was and it is now ready to use and we no longer have the problem.
just a suggestion...if you take some baking soda and some vinager you can clean the drain out. just simply poor in the soda and then the vinager.and it will fiz cleaning your drain.

first I removed lower basket. then removed lower sprayer attached to pump housing by unscrewing the cap by hand. the I removed the pump cover . there were six alan screw two of them were missing causing the failure of the seal spraying solution at the door. replaced the pumpseal working backwards until everthing was replaced.

Pulled off the old valve using a crescent wrench and screw driver. The replacement part was a 100% exact match. Slapped on the new valve and that baby was water tight. $50 on a new valve is a lot better than $500 for a new washer.

Partselect.com was so easy to use and find the right part. Way more helpful than whirlpool's site, but that's not surprising seeing as they have an "authorized repair technician" page.

Thanks Partselect.com!

The cap.nozzle is critical in transferring water to the
upper wash tray in the "heavy wash" cycle only. If this part is defective, simply unscrew it by hand and install the new one by hand in seconds. This
part is inactive in the "light wash" cycle.

Look for deteriation in the black rubber area of the
cap. nozzle.

Ordering and tracking the shipment was a breeze,
everything was very easy to do !!!!

I followed the video available on partselect.com and was easily able to follow step by step the process of removing and reinstalling a new Drain and Wash Impeller and Check Ball.

All I had to do is lay the shield over the top and sides and used a couple of clips to hold in place as it was slid under the counter top. It couldn’t have been easier.We had searched everywhere for this replacement shield and parts select was the the only ones that had it. Very good service and fast delivery,

just thru old basket away put new one in very happy thank you will buy parts again thru u people again

Had to be careful positioning the spring without breaking the hinge pin. Requires a certain amount of patience.

Turned off electricity. Removed the interior door cover. Removed door switch. Replaced switches & reversed process. By the way - I am a woman & diagnosised, ordered part & fixed it myself - I have no experience in this field. THANKS for all your information on your site.

I used a pair of needle nose pliers to remove the
Upper Wash Arm Support Clip from the broken support arm. Very quick re-assemble with the new part and I was able to re-use the support clip. The upper wash sprayer unit with its new support arm easily clipped in place on the upper rack.

but the pin in and add the pin though the 2 tabs close door on it open it up move the springs backwards to the door

All I had to do was remove old door panel and retainer and I replaced with the new.
PartSelect were great. I highly recommend you guys.

Pulled off the bottom trim, slid the old panel off and put the new panel on. Then popped back on the bottom trim.

Ordered a new upper spray arm from PartSelect. Shipping was fast and the correct part was recieved.
Use a hair drier to warm the prongs that mount to the upper basket. The plastic is softer and will squeeze/fit in place without snapping off the "ears".

Just put it on by hand, works great now, saved me at least 50.00!
