i always disconnect the atomizer and the battery once I get any sort of flashing on my 801 or 901. I'm so afraid of it hitting the cleaning cycle, which has cooked 2 atomizers on me to the point that they were red hot. After the cleaning its useless, horrible taste and very little vapor. If you get a cleaning flash you can override it by just unscrewing the battery and the atty, the battery will still flash but at least the attomizer isn't getting burned up.
