So I figured out why my steamer was attacking me.
More than once I jumped out from under it because it was spitting boiling water onto my scalp! It also ran out of water before the cycle was finished, which it's never done before. It seemed to be using--and wasting via scalding my scalp--a lot more water than usual.
When I finished I noticed that the reservoir was empty. When I lifted the hood, water gushed from it. Evidently it doesn't drain efficiently when the hood is all the way down at a 90 degree angle.
I'm learning, lol...tilting the hood and lowering the stand for next time!
