Product review (5 stars): This worked out great; replaced my 3363394 perfect on my Kenmore 600
After a month of running the spin cycle over and over again I researched the Internet and it seemed like the drain pump was the problem.  So, for $13 shipped, it seemed worthwhile to give it a DIY try.  The part came quickly and I had an hour before the family would be home.  Well, I didn't have the same 5-15 minute experience others may have had, but it was a success.  Most of my trouble was in getting my Kenmore 600 open.  I had clips underneath that you can get with a putty knife, but I didn't know that so I wasted a lot of time trying to get the plastic caps off to look for screws.  After a while, I was inside and swapping the pump was a quick 5 minute job. However, then it took me more time to get the machine closed up correctly.  That guy on YouTube did it so quick.  Anyway, the whole project took me about an hour and saved me $ and time trying to coordinate my schedule for a service call.  The machine is running like new now.
