Family Laundry - Evansville for Model Number MAH21PDDWW Where can one purchase the rubber flap on PN Whirlpool 25001052 displayed at 3 minute mark into above video? This flap hardens and does not seat and causes 'pump failure'. Family Laundry, jimtownlaundry@bellsouth.net
Answer You're not quite correct, the black flapper in the drain pump outlet is a "check Valve" or anti syphon device. It does not allow water to flush back into the washer, They can "stick" but that wouldn't normally cause a drain pump to fail. At present, the "flapper" is not available as a separate service part and you'll need to order the complete drain pump. Read More... Answered by AppliancePartsPros.com | Tuesday, November 14, 2017
