Water would not drain from washer

The drain pump was easily acessible at the front of the washer. There were only two screws to remove. However the two clamps holding the in/out drain pipes were a bit tough to release. When installing the new part, it made it easier to attach the drain pipes first before reattaching the two screws. We were able to get one clamp on fairly easily but the other we finally gave up on and put the old fashioned screw-type clamp on. It worked fine.
