This depends on where you live in. AFAIK, in Europe dishwashers are not even hooked up to hot water, just cold. In America their standard plug electricity is weaker and therefore it’s not enough for a dishwasher to heat the water hot enough to sanaitze.

This is the reason electric kettles are not a big thing in America (they take significantly longer to heat the water) and “home electrification” is a bigger deal there.

And as always, to anyone interested, Technology Connections talks about this in his videos on dishwashers, induction stovetops and kettles.
