      I think it’s everywhere but in the US the water comes already hot, in Europe the dishwasher heats it up from the regular cold water.

        That seems way less efficient and more prone to issue than just having a central appliance that’s responsible for making hot water.

          That wouldn’t work with every dishwasher I’ve ever had. They all start the cycle by draining any liquid in the dishwasher before they fill to run the first pre-wash cycle.

            Oh. Admitably I’m not an expert, I’m still ony first ever dishwasher. I did that when our water heater died and it seemed to help.

      This is crazy to me. How do the dishwashers in US heat the water up hot enough to clean effectively? Our dishwashers heat the water up past scolding, really helps cleaning.

        Every dishwasher I’ve used in the United States has a built-in heating element. Mine has a steam sanitize function and gets quite hot.

        However, it is conventional here to plumb the dishwasher to the hot water line, and it is my understanding that the dishwasher is designed to assume the water is hot and doesn’t try to heat it from cold during the first rinse.

        I’ve found that running some water from my kitchen sink to prime the hot line with hot water makes the dishwasher more effective. I use that water for plants, or I keep it in a jug and pour it into a load of laundry in the winter.

        There’s a heating coil in the bottom of the unit. Water floods in and sits for a short while while reaching temperature.
