Perhaps you should check out commercial washers. The kind that you find in laundromats are designed to take a lot more punishment than the residential ones.
Turns out around here (Scandinavia), the brand to beat is Miele, which also seems to enjoy a near monopoly in pro gear, from what I can tell (Just about every vessel I've ever sailed on carries Miele gear in their laundries. I cannot recall ever seeing anything else.)
Also, after asking around at a place repairing appliances as to what brands they trusted in their own homes, the answers were similar - 'Miele. Or, if you think that's a bit over the top, ASKO. Both are made to last and to be repaired.'
So far, the ASKO stuff has stood up very well - ten years in, both dryer and washer are still working flawlessly - and I've got three kids; running two machine loads a day is pretty much standard fare, and has been for years.
Especially when it comes to laundry, the 'European' style is to use longer cycles that are gentler on clothes, quieter, and usually more efficient (whether on water or power use).
The two-year old runs around outdoors in kindergarten all day. More often than not, it is rainy and muddy.
The youngest still run through a couple of sets of babywear a day, down to a somewhat lackadaisical approach to her excretion of various bodily fluids.
We all swim weekly. Add to that the occasional nightly mishap by the child currently quitting diapers, and you're looking at lots and lots of laundry cycles.
Good thing water is free (It's not that we haven't got plenty of it to go around!) and power is cheap.
- The manufacturer of a commercial appliance usually won't provide a warranty for it if it's used in a residential setting. - Your homeowner's insurance probably won't cover anything related to using commercial appliances in your home. - In certain cases (probably not a washing machine, but certainly other cases like kitchen appliances), commercial equipment has different standards and codes that can be hard to accomodate for (this can be especially relevant for stoves and ovens)
Install them in your home at your peril.
I bought some restaurant grade coffee mugs that are just fantastic. Pretty much impossible to chip and guaranteed.
The same goes for ranges, ovens, refrigerators, microwaves, you name it.
