I replaced the old door bellow seal with a new one. I referred numerous time to an instructional video I found online showing the steps to take to make the repair. There was a considerable buildup of material that appeared to be a mixture of soap scum, dirt, oils, and mold in areas of the old door bellow seal that were not reachable until it was removed. The hardest portions of the process were installing the inner ring of the new door bellow seal onto the washer itself and installing the wire ring clamp on the front panel of the washer.
