George C Pasadena , MD December 04, 2015 Appliance: Maytag Washer- Horizontal Axis MAH3000AWW Maytag Washer Mah3000aww: Moldy door seal. How to replace Door Boot Seal. I studied several online videos before attempting to replace the seal, including one from appliancepartspro. Mine was an early Neptune model (MAH3000AWW), so the videos did not exactly cover every detail. My model was not equipped with a drain hose for the door boot, so I drilled through the drum and installed one. However, the nipple on the drum was somewhat smaller diameter than the drain hose which led to leakage until I really tightened it down. The repair turned out to be more difficult than I anticipated. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
