About a quart of water is in the tub after it goes through the drain cycle and sits
Empty for awhile. If I close off the water supply that seems to end the problem.
I’m thinking there is a valve in the washer to prevent this condition that is not
Working and needs to be replaced.
Here are your parts

I would replace the water valve (item 1 in section 04).
