I was so sure the answer was going to be no. TIL

It’s correct if in a country where the dishwasher lacks its own water heater.
Dishwashers in the U.S don’t have water heaters and therefore it’s beneficial to purge lukewarm water from the hot water line before starting the dishwasher, such that the water in the dishwasher is on average hotter and as such more effective at washing the dishes.
Dishwashers in Europe have water heaters and as such it’s entirely irrelevant to do it there

Crazy. Mine only takes in cold water. Never even knew ones that take in hot water existed.

You’ll be surprised to hear that U.S washing machines have the same setup, and this is why they talk about “wash cold” or “wash hot” instead of having specific temperatures on their washing programs like 30 C, 40 C, 60 C etc.

How do you do a 90°C wash? Surely the tap water doesn’t get that hot.

I wouldn’t know unfortunately, I’m in Europe.

The washing machine heats the water, many go up to 95°C

As a European that carefully checks the temperature levels indicated on the clothing before washing, I feel like I did it wrong - or at least overly complicated - my whole life now 😅

It’s because the US electrical system sucks and they refused to upgrade it, although reasonably speaking it would be kind of impossible at this point. In order to be able to actually run a heating element you would have to have a special circuit fitted with a decent voltage.

Ah that makes sense. Cheers.
