Product review (3 stars): So-So Machine
My model is the WPRE6100, which I bought 11/08.  All the weird noises it makes supposedly are normal.  the actual washing agitation is pretty quiet, but it does make other noises that are loud (clicking noises & the drain/spin cycle).  Comparing this machine to my previous 25 year old Kenmore machine (back when Kenmore was Kenmore), it is quieter, but it does not clean as well. maybe because of the quiet factor with agitation? and the maximum hot water temperature for this model is 115 degrees even though my faucet temperature is 130, I think because its an energystar?  You need 130 degrees to kill dust mites on towels and sheets. The tub is big and stainless steel which is nice and I really like the option for a 2nd rinse and extended spin.  If I had to do it over again, I don't think I would get an energystar brand.
