I think it is more a 110V vs. 230V household power issue. For 110V countries like the US the amps needed to heat up the water would be pretty high or the heat up would take very long. In Europe however I have yet to come across a dish-washer that is connected to the hot water supply.

Scrolling through these made me remember that some years ago Katie Melua played a concert on the bottom of the "feet" of Troll A platform (number 4 of the list). Apparently world record for the deepest concert. Absolutely mind blowing scale.
