I have a Kenmore that I bought in 2006. It was highly rated by Consumer Reports back then. It's been a great washer. There is one caveat. To meet energy ratings they wash at a lower temperature with less water than years past. If I have a full dishwasher with lots of crud I'll run the pots and pans cycle with hi-temp setting.
Dishwashing detergent makes a huge difference, too. I bought a store brand and it didn't clean worth a shit. I switched back to Finish All-in-One tabs and things were normal again.
