Product review (5 stars): So Easy To Install!
It was the EXACT same item on the Maytag/Whirlpool website for half the cost!  It came in a Whirlpool box but without any instructions, but it was easy to install.  FIRST - unplug your washing machine from the power and remove the lower front panel.  Then open the filter/drain with a bucket underneath to catch leftover water.  Then, simply remove circuit cable (squeeze release and slide it out) then remove the two water hoses attached but squeezing the clamps, then slide the old pump out.  Insert the new pump in the same way the old one came out, reattach everything, then start a load.
I did not put the cover panel back on the washer at first, as I wanted to check for leaks.  After running a quick load and all worked well, I put the cover panel back on.  Saved $75 on the part, and $150 for the service call.
**of course, I did NOT want to have to replace this part after 5 years, but I didn't clean out the filter so it was my fault!
