Ron C Fulton , NY June 28, 2015 Gunk just gunk Replaced both flap valves....one wasn't even on the discharge hose. Still did not drain. Poured a glass of water with 2 tablespoons of vinegar and one of baking soda into the grate at the bottom of the washer and WOW IT WORKED. Fixed that. Gonna do that every month. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
