I replaced the circulation motor, which with the video was extremely easy. While I was under there I replaced the drain pump too just because the washer is 17 years old - purely preventative since it was cheap. I also replaced the dispenser, again, while I was in there.....
The whole job was a snap, there is really nothing much under there and it all is easy to access. With the video to give a few hints like “just snap that tab off because you will replace it anyway” I’d say anyone can do this repair.
