I did replace the pump which was very easy. The threads on the old pump were fairly stripped so it was hard to keep tension on the belt. At first I thought lack of tension was causing the drain problem. The real fix was clearing the hose going to the pump- that had a hard, felted, ball of wool about the size of a small mouse.
