Friend has an HE<sup>3</sup> (not t) pair. Blue color.
Washer 110.448626300 \ CSP3810240 (38th week 2003).
Dryer 110.82826102 \ MP5110208 (51st week, 2003).
That makes the set 12+ years old. They're used relatively "hard" ... she fosters rescue dogs so has a lot of critter-related laundry. Typically 23 dogs in the pack, which doesn't include resident cats.
Dryer, no repairs.
Washer has had one repair, pump changed (by me) approx 3 years ago (which means the original bearings are still running). Found no mold/grunge in the sump, and interestingly no dog hair. There's no "machine clean" cycle. She uses chlorine bleach often, although not so much hot washes.
