I don't think this is a great example, because saving water (and thus the energy needed to heat the water) is both a social good and a private good.
Your new dishwasher program might take longer because, for example, (a) it's more efficient to soak residues than keep blasting away at them, but it takes longer and (b) if you alternate between shooting water at the the top and bottom drawers (but not both at once) then you can get away with using half the water, in twice the time.
Most dishwashers have an 'express' programme that uses more water and energy to finish faster, so if that matters you can still have it. If it doesn't matter to you (e.g. because you're running the dishwasher overnight, or while you're at work), you and everyone else benefits from the greater efficiency.
So I think this is an unambiguous improvement. :)
The average quality of appliances is a separate question. Anecdotally, I finally had to replace a 22-year-old Neff dishwasher. I got a new Bosch one (same firm, different logo), and have been pleasantly surprised that the new model is still made in Germany, seems pretty solid, washes well, and is guaranteed for 5 years.
