I know people in Germany who still wash lines/towels/underwe
because that's what they saw their mothers do when they were growing up.
My FL washer lacks a heater, so it cannot wash above hot water line temperature, which for me is about 140-150F or perhaps 55 C. Higher cost washers with a built in 120V heater generally use the heater only when "Sanitary" cycle is used, and only to heat the water above what is coming into the machine via the hot water line, since our washers fill from both hot and cold water lines. The definition of "Sanitary" cycle temperature varies by brand.
I'd say the majority of people here wash "hot" loads at 50-60C and no higher. I have friends with a KitchenAid FL (no longer sold, but appears to be a rebadged Bauknecht like Whirlpool Duets) with a "Sanitary" cycle. They rarely use it because it adds an hour or so to the cycle time, and with three children, they do not have time for cycles that run over two hours, since they usually run two loads a day.
