Fill the salt? I'm not sure all dishwashers have a receptacle for that. Ours doesn't, and I'm pretty confident that I've never had one that did across several states in the US and one place in Belgium. Is the salt for doing a softening process that substitutes for a whole house softener if you don't have one? We live in a place with hard water and have no softener in the house (you should see our electric kettle when…

My dishwasher has a "salt" light that lights up when the salt is low. The dishwasher is also 30 years old. Miele G 680 SC from 1992. Living in New York. Perhaps adding salt was more common in older models.

I have a new-ish Miele which has it. Good thing too, because we have really hard water here.

Ditto, no clue what either of those mean. Never, ever heard of adding salt to a dishwasher, certainly. Not in new ones, not in ones from the bad ol' days when they used way more water but actually worked.

I have a new one (a few years old) and yes there's a compartment for salt. My previous one did as well. I'm in Europe (Spain) if that helps. I don't go to any special store to buy them, any old Lidl or other supermarket has it. Where you from where this isn't a thing?

From other comments it's looking like this one of those US/European divide things, with compartments for salt being uncommon on US dishwashers except for a few rare higher-end models/brands that are likely common to both continents (due to low volume in the US not justifying a localized version, I'd guess). I'm middle-aged and in the US and this thread is the first time I've heard of adding salt to a dishwasher.

I'll give you an upvote for that little dive into Wikipedia. For those who haven't already swum as deep, the article on ion exchange resins[0] is also worthwhile. Turns out they are used for reprocessing spent nuclear fuel as well as softening water. Plus a few other things. [0] https://en.m.wikipedia.org/wiki/Ion-exchange_resin

I did bad in high school chemistry, I never could understand this stuff. First, the ion exchange resin beads are washed with Na+ which bind to the beads. Second, the hard water is run through the beads and bad stuff like Mg2+ has a stronger attraction to the beads than Na+, so the Na+ is pushed off and Mg2+ binds to beads. The resulting water out of tap is softer because Mg2+ is out, but saltier because Na+ is in. Th…

Ca²⁺ is the more important ion, since limescale is mainly calcium carbonate (CaCO₃). Otherwise, the explanation is fine.

The exchange of the ions is driven be the difference in concentration between water and resin surface. It works both ways, but Ca²⁺ is preferred (=stronger bonds) by the binding groups (e.g. carboxylate salts). That's why a concentrated Na⁺-brine is needed to flush out the calcium ions.

maybe dont wash them that often

You should start a business: a restaurant that serves your food on the previous diner's unwashed dishes. It would be like my college apartment kitchen, so you could hire me as manager.

Hey wtf, you told me that the dishwasher didn't get all the dirt off, but it was OK, the heat sterilized it! Damnit Bob!

So what does this mean for all of us who buy coffee at coffee shops every morning? Will this cause serious problems long term since we are consuming residues of their dishwasher chemicals? One potential solution is to always get your coffee to go, but that probably only partly solves the problem.

What are you getting from a coffee shop that has been through a dishwasher? The mug?

Certain pieces of equipment are cleaned at the end of the night, so even if you bring your own mug you don't remove the possibility of leftover soap or sanitation solution residue.

"It's not common in the United States." If US folks are looking for this feature, it can be found on higher end Bosch dishwashers in the US. I have very hard water and a Bosch benchmark series. The water softener makes a huge difference. I don't want a whole-house softener because I don't enjoy the feel of softened water in the shower.

Why don't you like the softener water? I thought it was better for the skin.

It's easier to rinse soap off with hard water.

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.

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.

I suffered from chronic diarrhea for years which I attributed to Crohn's disease. This seemed obvious since diarrhea is a very common symptom of Crohn's, but its onset had been several years after I was diagnosed and prior to that I had tended more towards the opposite problem (constipation). I was thus always suspicious that the root cause lay elsewhere. After much experimenting I found that if I ran my dishwasher t…

I’m curious, did you ever try using less detergent? Like cutting one of those pouches in half? It’d be messy but maybe it’d work.

Softened water feels slimy to me - similar to seawater.

I actually do have a whole-house softener which came with my house. I installed a bypass valve so it does not feed the pipes in my home.
