I know Miele has a water softener feature. That's the only time I've heard of it in the US.

There are a few Bosch models with dishwasher salt dispensers, but it’s extremely rare in the US.

It’s a great idea, given most municipalities have hard water.

Yeah I need it with my well water. But generally we just put up with spotty dinnerware. If we have guests over, we'll wash whatever by hand before.

interesting.. I got a Kitchenaid but maybe I would have gotten a Bosch. I wanted a Bosch but they were on tremendous backorder compared to the Kitchenaid in 2021.
