I have the same problem yesterday, but I believe the pump is not working at all, I did a rinse cicle and I have water coming out from the door, so again I believe I have the pump broke, what the experts think,
also I cleaned all the filters and check the hose, but was working ok till I have to change the door handle, so its time to get a new one...
