Replaced the bellow. I had to use two different videos--neither showed my exact model and the replacement part in the video looked different than the one that was mailed to me (e.g., the washing machine in the videos showed the washing detergent tube going into the bellows, for mine, the washing detergent tube went into the washing machine enclosure).
That said, the part was the right part for my washer and I have used my washer several times since replacing the bellows and it has worked fine, without leaks.
