Maytag Dishwasher Not Draining
At the end of a complete cycle, there is quite a bit of (mostly dirty) water in the bottom - it comes up to the bottom of the lower rack. I then ran the dishwasher again and once again it was full of water.
If I leave the water in there and run the machine, I end up with the same amount of water as before.
The hose is properly connected to the pipe from what i can see. (no disposal, single sink).

Do I have to remove the dishwasher from under counter to fix this?

Unsure where to begin to sort out the problem...

Appreciate any help!

Model#? Some model# helps.

Don't -normally- need to pull out the d/w.

That has 2 motor and pumps, one for washing only and one for draining only.
First thing we would check is to confirm the drain pump is acually running. #15 in the pic here.

How do I get to the valves to check for blockages? Should I remove the bottom part on the floor of the dishwasher?

Check valve is just one item mentioned. It is # 5 in the pic here.

This here is for something else and more but will help get to the check valve.
