Power management is Miele's energy saver: booster drops to level 3 after five minutes, lower levels step down after two hours, and the light goes off after twelve. In the settings sequence the hood shows its state with 1 and B, flashing for off and steady for on. Miele range hood display What to do when 1 and B flashing shows on the range hood ### Kind of code Mode, not a failure The hood is doing something it was told to do, not wearing out: a delay-off timer that keeps the blower running for some minutes after the burners go off, a heat sentry that starts the fan by itself when it senses a hot pan, a Sabbath setting that locks the keys and dims the lights, or a link to the cooking surface that sets the speed on its own. No part is needed; a key sequence from the manual, or simply waiting, ends it. ### Usually leads to No repair Touch B to switch power management on, or 1 to leave it off. ### Shows up as Reading a Range Hood Error Code or Blinking Light A range hood error code may appear as letters and numbers on a display, a light that blinks in a pattern, a filter reminder that will not clear, or a beep with the fan refusing to start. ### Make Miele Miele range hoods are serviced at home, with filter reminders and automatic settings separated from real failures on the first visit. ### Source Miele DA 6698 W Operating and Installation Instructions (en-US) DA 6698 W wall hood. ## Before you book, in this order. Each step comes from Miele's own guidance for 1 and B flashing on its range hoods. Follow it to the end: the last card says whether this is a visit. 01 Touch B to switch power management on, or 1 to leave it off. 02 Confirm with the delayed shutdown control; the lights go out. 03 If you do nothing within four minutes the hood keeps its previous setting; book a visit if the settings will not save. ### Cleared? The code is gone and the blower pulls steam up on every speed again without a new part. If it returns this week, or the filter reminder keeps coming back right after a cleaning, mention it in the booking. ### What not to do 1 and B flashing are not a warning and only appear in the settings sequence. A blower that steps down by itself during long cooking is power management at work, not a failing motor. ## What you may notice with it. The range hood problems 1 and B flashing tends to arrive with. Answer these at the range hood before anyone is booked.

Touch B to switch power management on, or 1 to leave it off. ### Why does my Miele hood drop from booster after five minutes? Power management is on. It cuts booster to level 3 after five minutes and steps lower levels down over time. ### What happens if I turn off power management on a Miele hood? The hood holds your chosen level, but it switches itself off after twelve hours if left running. Energy use goes up. ### How do I reach the Miele power management setting? With blower and light off, touch the delayed shutdown control for about ten seconds until 1 lights, then press the lighting control, 1, and the lighting control again. --- **[Read on the site: Miele 1 and B flashing: power management is switched off](https://rangehooderepair.center/error-codes/miele-1-and-b-flashing/)** **[Book a visit with RangeHoodeRepair.center](https://rangehooderepair.center/schedule/)**
