This looks like a specific kind of… fungus?..aging?. I can’t find an English word for it, but it looks like the black spots you get in clothes when you leave them in a wet pile for too long. In Dutch, is called “spocht”.
a lot of the reviews for the kettle I bought on amazon had reviews that complained about this stuff, but we buy filtered water in those refillable 5 gallon jugs and havent had an issue, we have hard water out the tap so i try to avoid using that for cooking, but also I wouldnt trust a used kettle, Id imagine its like the hotel coffee makers where people probably poop in it

We call that mold or mildew.
I wiped them off with my finger the first time, it looks like chalky white powder.
The next batch of water we boiled looked fine. The batch afterward had this residue again
