Washer would not drain. I took the drain hose off at the pump and found a rubber part in the hose. I removed it and the washer now drains. Does this piece act as a anti back flow device? Is it suppose to be in the hose?
Answer Joe, Yes, Correct on both counts, there is a back flow device in the drain pump, and it should be in the exit port of the pump, not in the hose. Your washer should work fine with or without the flapper, as long as you have no drain/plumbing issues. Thanks and Good Luck
