Product review (5 stars): Easy fix - don't waste money on expensive service call!
Perfect fit in a flawed washer.  Found an install video on Youtube, and in total took under 30 minutes to replace. You will need a couple tools, google the video for help.

I feel the washer has a flaw where the door puts extra pressure on the bottom of the seal, causing it to misshape over time, which will leak. Not sure if it is preventable, but the fix is easy enough.
