The Whirlpool WPW10467168 pump hose helps transfer water between the tub and pump system in a compatible washing machine. Designed as part of the washer’s drainage assembly, this flexible hose provides a pathway for water to move through the appliance during draining and other designated cycle stages. A properly fitted hose supports consistent water flow and helps the washer complete its cycles as intended. Replacing a cracked, split, clogged, or leaking hose can help restore proper drainage and reduce water leaks around the appliance.
