Do-It-Yourself Stories from Customers like You Thrashed the door panel & seal   Timothy Y. • Newmarket , NH • December 20, 2015

I replaced the inner door panel, vent grommet, and door boot seal. Replacing these items was pretty straightforward, especially with the repair videos playing in the background. The only "challenging" things were getting the boot attached to the drum area and removing/reattaching the spring+cable around the boot seal. The total time also includes cleaning the inside of the washer and using some anti-rust jelly on the top panel near the detergent door. Washer is working great now. Read more
