Got to the website, and couldn't figure out the correct replacement part, so I asked the online chat support.
The rep was extremely friendly and helpful, and got me the correct part.
The installation was pretty straightforward after watching a couple of Youtube installation videos. The only hard part was putting back the spring band around the part to hold it in place.
I have a load of clothes going right now, and it looks like the seal is tight and everything is back to normal.
Thank you!
