kenmore stackable washer will not drain water. I have remove rubber drain hose on rear of washer and it is not clogged. I ko=now it is clogged inside the washer somewhere since my washed a rug and it ended up in a million pieces. What is the best way to unclog the internal drain line.

I would start at the water pump first since it would be a good location for a clog. Also check the lint filter for the water also if so equipped.
