Dishwasher doesn't drain completely

Plunging a stopped up sink left stinky water in the dishwasher. (no air gap on this one, and we don't use the dishwasher much, I just didn't think ahead about forcing water that direction).
Running a wash cycle left an inch or so water in the bottom of the dishwasher.
I assumed the sink drain wasn't clear enough, so I pulled the trap and snaked the drain out. It took a long time, it was pretty narrow somewhere in there.
But the dishwasher still doesn't drain completely, just most of the way. I ran a smaller snake through the dishwasher drain hose, it seems clear and the copper part gets plenty hot, so some water moves through there.
What to try next?

Did you clean the strainer inside the dishwasher. It should say in the owner's manual that you need to periodically clean the strainer.

What style house? Bungalow with basement, 2 story with basement, etc.? No access port the snaking the drain main pipe from the sink down? Also disconect washer drain hose and using an empty bucket run the washer to see if it drains OK or not(to prove what you think is right) Does the sink drain water slower than ysyal? Is the vent stack clear?

Go to repairclinic.com- put your model number in and see what they say.
If it was my dishwasher I would suspect a clogged impeller screen or a faulty flapper valve. Neither is expensive nor hard to get to.
repairclinic will guide you right to them in most cases-- and their service on parts is excellent, their prices reasonable, but could be better.
I like to support them because they have such good help online.

Hit "Cancel" and wait a couple seconds. If nothing happens hit it again and see if it drains the remaining the water.
Then run another wash cycle and see if it drains completely. ----- - gpsman
