I LOVE my Whirlpool Duet and none of the things Xeney complained about are a problem for us. We don't wash diapers, but my husband's work-out clothes get pretty rank. We started adding Febreeze laundry additive to those washes, and that made a difference. We have extremely hard water that leaves residue on surfaces, so maybe mine works better because of that...I dunno how all that works (but I hope the P&G folks will chime in). My clothes are cleaner with the Duet, and it's wonderful. I love it.
I just made a habit to press the "Cold" button whenever I wash. I do that to save money on heating the water. Nothing has shrunk, though, even on warm. Maybe my water heater is not up enough (the former owner put a partition around it and I've never even seen the stupid thing).
I'm sorry your Duet is not working out for you. I'm sure someone would buy it if you decided to sell and get something else.
