Water seeping from floor in laundry?

Water never drains completely from the washer. Check the drain hose.

Dry the floor as well, and lay newspaper down, to pin-point the source.

It sounds like your drain pipe is possibly leaking. The hose in the back is emptying water into a drain pipe inside the wall, it could be a break in that pipe, which would have water coming out from the wall. Hope this helped.

You might also check the water filter. Also check drain and water hoses.

Maybe you now have baning problems. Could the seal be worn as a result? Overload problems maybe?
