In the U.S. dishwashers are almost always installed directly next to the kitchen sink, where either the cold or hot line can be easily tapped with a tee valve. I guess plumbing/kitchen layout is done differently in Europe.

As for heat setting, what’s the reason to be concerned with tap water being too hot? I don’t think plumbing code would allow water to be available at the tap that was hot enough to actually damage any type of utensil/drinkware/etc? I presume the only reason there might be a lower heat setting is simply for energy savings, which is kind of moot if you’re instead pulling hot water from the efficiently heated water supply.
