Product review (5 stars): Perfect replacement pump for Maytag MHWE450 series
Purchased this on a Friday and arrived the following Monday.  Sold by Prime_Source and shipped by Amazon via Prime.  The product looks identical to the factory part and I believe it to be 100% Genuine Whirlpool product.  This was installed in my MHWE450WW01 (MHWE450) Maytag Front Load Washing Machine in less than 5 minutes. For a how-to, there are videos online, just search for 280187 replacement on a popular video site for guidance.  I washed my first load minutes later and it worked perfectly.  I am very happy with this purchase.  I'm thinking about buying a spare just in case.
