@pfr @homeassistant just remember that this machine needs to clean it’s pipes too, just using chemicals for that won’t do very well i guess. I’m not saying that this is logical (making this eco mode) but using more electricity for hot water and using more water (for not reusing too much water all over again) is probably the sweet spot for lasting much longer. Which in turn is not in the interest of the company selling these machines. I guess.
