No? I'm in Germany, all dishwashers I've ever had were connected to cold water and heat their own water.

My dishwasher is connected to a hot water tap and also heats its own water to exactly the correct temperature... it just doesn't need to heat it as much because it's connected to a hot water line.
Here's the install guide of a random dishwasher selling in Germany right now: https://media3.bosch-home.com/Documents/9000521334_L.pdf
It says to connect to a water source with these characteristics:
* Pressure: 0,05 - 1 MPa (0,5 - 10 bar) * Temperature: max 60°C
It doesn't specify a minimum temperature although I assume it'd have to be >=1°C. But it is clear you can connect to either a hot or a cold water line.
And what for? Whether the instant water heater or the dishwasher heats the water, it's still going to be the same amount of electricity, the same cost.

I think in the US people might heat water with natural gas, which is cheaper, but that's not really the case in most rental apartments in Germany.
