Maytag washer doesn't drain completely?

We have Stackable Matag washer model MHS2000AWW, style yooooooo. After a full washing cycle the clothes come out wet ofter and three is some soapy water remains in the washing tab. The pump is working as I can hear water being drained from the machine. I had disconnected and cleanded hoses from the tub to a pump and from the pump to a drain and drained water from the machine. But I still hear water splashing betwenn the washing tub and the machine frame, when I turn the tub by hand. When I assembled and run my machine again the problem was still there.

Thanks,
