Just a note on the hot water supply: Whether this happens depends on three factors:

- Does the dish washer support it? Not all do in the EU.

- Did the plumber install a warm outlet when they set up the connection for the dish washer?

- Does it even make sense from a holistic perspective?

The latter depends on the specific circumstances. For instance, I live in a country with district heating, and here it makes sense, because then I can use cheap heat. My dish washer supports it. But there's no warm outlet installed by the plumber, and currently the heat is mostly from coal, whereas the electricity is mostly renewable, so for the time being I just let it be.
