The washing machine standpipe is designed to prevent drain water from re-entering the washing tub or spilling onto the floor. Drainage problems can be prevented by installing a standpipe that is at least 36 inches in height, and placing it at the height recommend by the washing machine’s instruction manual. Low standpipes are prone to overflowing, and those that are placed too high make it difficult for the washing machine to pump out drained water, which results in backflow.

A washing machine drain hose with knots and twists can cause drainage issues. Drain hose problems can be improved by minimizing bends and kinks, leaving adequate space between the wall and the washing machine, and purchasing a new drain hose if the damage cannot be repaired.

Lint and laundry debris clogs can form in the standpipe, drain hose and drain, which can be another cause of drainage problems. Using a plumber’s snake to clear the clog can improve the washing machine’s drainage. Chemical drain cleaners must not be used to remove clogs to avoid clothing and washing machine damage.
