I just purchased a new wash machine pump because I was getting error code F21 and SD. I clean the pin trap regularly even prior to replacing the pump. Now it cycles through without error coding but about two cups of water remain in the pin trap. I am emptying the pin trap every load. I want to know if anyone knows why that even with the new pump water is not completely cycling out?
