My original Duet is about the same age, no issues. I bought it used in '10, had a lot of animal hair in it. Gave it a good cleaning and it's been cleaning well since. It's German made if I recall.
My second Duet is on the disabled list with the bearings going bad for the second time, plus it has a bad sensor and I keep getting a Suds error. Will dig into fixes, new replacement is $$$, there are some used ones on ebay for a more affordable price. I have a third Duet that needs bearings too, but only have hookups for 3 machines, my little used Kenmore electronic version c.'95 has that spot.
Funny it's only me, but I really miss being able to load up 2 machines and get my laundry done quickly.
