Product review (5 stars): Easy Fix!
My washer started making a weird noise when it would hit the drain cycle, just what I needed right before our 9 week old puppy arrived!  It took me a little while to figure out how to open up the washer to replace the pump, but it was very easy once I figured that out.  I did manage to get the floor pretty wet when removing the hoses.

I'm decently handy, and if you can follow a few youtube videos, you can fix your washer no problem.  Also make sure you have a good ratchet set, great excuse to buy one otherwise.
