> The dots always represent the three levels of heat, just like on your iron.
Just to highlight how non-universal these symbol are, I have never had an iron that has three levels of heat or that represents the levels with dots.

Funny thing, those two do not match. For example, on my current iron "Cotton" is marked at three-dots, whereas all my cotton clothes have labels that insist on ironing them on two-dots.
