What started as a quest to rid the stench under my sink has turned out to be quite a challenge! I thought the smell originated in under the sink, so I disassembled the pipes and cleaned out 12 years of stinky sludge. That helped some, but was not a fix.

I removed the dishwasher drain hose thinking that may have been blocked but could not see any (really couldn't see much of it). After reading a similar thread here, I ordered and replaced the piston and nut assembly and the large tub screen/gasket since it was absolutely disgusted even after cleaning. When I removed the old gasket, that was when I noticed the standing water in the bottom. Not a lot but still not draining all the way. I cleaned everything to include the crud down in the sump. I can feel the impeller spin freely. I hoped cleaning would solve the problem, but no luck. I can still feel water in the bottom when I touch the screen.

Not sure if I should disconnect the drain hose and attempt to see if it drains (or how to do that). Thanks in advance.

There is a small about of water on the floor.
Also, when I replaced the screen I snapped off both of the plastic tabs that the nuts secure to in the front. I tried to be careful but they were very brittle. Would would you suggest using to secure the front of that deal. Maybe a brad of silicone?

The drain hose runs from a drain pipe under the sink thru a hole in the cabinet to the dishwasher. I can see about two feet of it. Should I remove from the pipe and check the drain flow?

Sorry for the delay. There is more than 32" above the floor for the high loop, the manual was a great help. Still haven't completely solved this, I have two ideas.

1. The waste tee is mounted horizontally, not sure if that is contributing to the problem. I have a pic, but not sure how to attach it.
2. Beginning to think the inlet valve may not be functioning properly. Maybe not closing all the way?
