Model # DU850SWPQ2 Whirlpool dishwasher
Type 280-0
Unit will not drain after a complete wash/rinse cycle complete. I was able to siphon water out of drain hose so I don't think blockage is the problem.
Has just started to happen in the last 3 weeks.
Hello Tom,
Glad that you were able to find something out of place in the check valve ( like the gasket) which in turn was restricting the ball in that check valve from being in the right position. I'd be willing to bet that your problem is solved..

It was the "check valve", well the gasket( O ring) was blown out.
Thanks very helpful.

Hello Tom_Simmers,
Here is a link with exploded views and parts lists for your dishwasher for reference however based on your description, have you made sure you don't a blockage in the check valve? That's part of the pump drain assembly. http://www.pcappliancerepair.com/model-display.php
You may also have a problem with the pump itself so the documentation on the website will help you evaluate that.
In many instances, its just a blockage of food byproducts inline with the drain system so chances are thats what you will find.. Good Luck on that.
Regards,
Rick

The website did not prove useful, but the suggestion to check the "check valve" was helpful. I removed the machine and found the checkvalve on the bottom. I found a rubber gasket that was blown out of place and stopped the ball in the valve from moving. I simply replaced the gasket - where I thought it should be or looked like it should be - and it seems to work fine. Time will tell.
