Product review (4 stars): UPDATED - saved my pump and $300
UPDATE- had SAME problem again of no/slow pumping for the FOURTH time.  New pump was just 14 months old.  But in my install of that new pump in 2013, i very carefully built a screen that I put inline just before the pump. (Do NOT try this if you don't know what you are doing!)
It SAVED yet another case of "someone" leaving change in their pockets.  removed pump (10 minutes), cleared the coin from the screen, and reinstalled.  Impeller blades were saved!!  hurray!
So instead of clogging the pump itself and damaging the impellers, and then buying a fourth pump, it just clogged my screen, I just cleared the clog in 5 seconds.
If the washer manufacturers would just put this screen into their designs, it would save millions of hours of wasted time and money for us owners.

Original Review-
A failed pump is one of the most common problems with almost any washing machine.  In my case, I am still teaching my wife that COINS cannot go into the washer.  this is the 3rd pump in 8 years.  but having coins in the pump will simply chew up the pump vanes or worse, burn up the motor.  This took only about 20min to install.  and most of this time was just spent trying to minimize the water spilling from the hose and avoiding a mess.  Just use the control diagnostics (read the manual) and you can confirm if your pump is dead.  Repair guy was going to charge me $150 to "look at the washer."  and for sure another $200+ to repair it.
IF they would sell just the pump vanes, I would buy 6 of them to keep on the shelf.  Too bad they do not incorporate a course screen in the inlet.
