I have a Roper Washing Machine that during either the fill on the wash
cycle or on the rinse cycle, that decides to drain in the middle of
filling, it drains all of the water completely and the machine
continues to attempt to fill.

The drain hose is looped about 1 foot above the back of the washer.
From there the drain hose then dumps into the drain.

Any ideas what may be wrong?

thanks
