Customer Questions and Answers for Washer Drain Pump by Whirlpool

Hi Steve. This is called a siphon-lock. Look at the drain hose and pull it out of the standpipe. Make sure there is a gap in between the drain hose and the standpipe opening. It needs proper air also while it is draining. You may need to extend the standpipe higher then the top of the washer. Use a Y-pipe and a anti-siphon cap on the top of it to allow air to be drawn in while the drain pipe is in the side Y-portion. Use drain-o in the standpipe while doing this. Your drain hose is only needed to be inserted 6 - 8" only. Thank You.
