James B Plainfield , IN February 21, 2015 Appliance: LG Washer WM1812CW Lg Washer Wm1812cw: Mold. How to replace Dispenser Hose. Replaced the dispenser assembly, door gasket, and the bellows because there was mold in the first two. Replacing the bellows just seemed like a good idea since it attaches to the dispenser. The dispenser was super easy to replace. It required a Phillips #2 screw driver and a pair of pliers. 2 screws on the back of the machines top cover (the lower screw on each of the hinges), pull the top cover (slide it toward the rear about and inch and a half, and the lift the cover up and off) The door gasket was more involved. Check out the videos on this site and YouTube. The most difficult step was removing and replacing the spring wire that holds the gasket to the tub and the front of the washer. All of the videos that I watched suggested using a special tool that would make the process easier, but I was able to accomplish the task with 2 pairs of heavy needle nose pliers. I wouldn't suggest going that way to just anyone though. You risk poking a hole in the new expensive gasket when reinstalling it if you aren't very cautious. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
