@alda@TechConnectify last time I was looking for a dishwasher, I stumbled upon a dishwasher which had both hot and cold intakes in Currys. Having never seen this before, I promptly called my parents to ask if it was a good idea. My logic was “hotter water = betterer”.
Thankfully they steered me away from using hot water intake. Their main point was; “Why heat water for a whole house and use a fraction, when the dishwasher can just heat the amount it needs?”
