Product review (4 stars): Door Seal/Boot replacement
I have the Duet GHW9100LW0 (basic release 2002) and recently ordered this replacement seal.  The 8182119 is a newer version for the -W2 Duet model, however the seal fit perfectly.

I did have to modify the seal, my older version has a small hole at top dead center for the window cleaner water line.  This seal has a marker-dimple that must be punched out and then the water line nozzle will snap in and seal.

If you do not want to cut this hole, make sure you verify the older revision of the door seal, but this was very easy with an exacto knife and after 3 wash loads and one clean run, no water leaks at all.

The youTube videos give a good overview of removal/replacement, I was able to replace the seal without removing the face of the machine, but I can see where it would have been much easier to align the seal and clamp in place.

As most people report, the spring clamp on the outer end of the seal would be much easier with 3 hands but possible with 2.
