We, too, bought a Whirlpool Duet two and a half years ago. Yes, it used less water and less detergent, and yes it spun out more water (thereby shortening drying times), but were never really happy with it. No real “pre-soak” capability, and it also didn’t completely wash out stuff like sunscreen that invariably got onto T-shirts or cover-ups or whatever – and that was when the machine was working as designed!
But after two years, our machine stopped working as designed… The door lock mechanism failed (wouldn’t unlock even after the machine stopped), the electronic control module failed (it kept reporting an electrical problem), and the switch that controlled whether or not the machine filled with water failed (we’d leave the door slightly open after each use so it could dry out, but instead it would fill with water and eventually spill out onto the floor) – all within a few weeks of each other (and, of course, all after the warranty had expired). For what it cost to repair, we could have bought at least two or three standard no-frills washers!
In an attempt to keep us as satisfied customers, Whirlpool’s customer service folks did make us a deal that was almost too good for us to pass up… but when we asked the repairman, based on his experience, what further repairs we could expect to have to make in the coming years, we were shocked to learn that on average after 6 years or so the axle bearings tend to start failing – because the drum is hanging on its side instead of balanced on its center like in a top-loader – and at that point because of the expense involved most folks replace the whole machine rather than repair it. We certainly didn’t want to spend a whole bunch of money to repair the things that were wrong with our washer, only to potentially have to replace the whole thing anyway in as little as 3-4 years.
