Fine enough advice, except for the tap water comment, which I would think might lead some to distilled water (so it’s not “saturated with impurities”) - that’s not the way water and coffee work, and indeed, in a water-sensing machine (which likely depends on minerals in the water), not the way equipment works either. If one takes that comment to its logical conclusion, you’re going to have a (poorly flavoured) bad time.

Agreed. I don't bother filtering my water, the tap water where I live is pretty great though. I imagine that might not be true everywhere. Some mention about the mineral content of the water would have been appropriate, ad you mentioned.
