Miele's ventilation documentation describes a separate symbol for the charcoal filter used in recirculation mode, which lights up when that filter is due for replacement rather than washing. Miele home appliance display What to do when Charcoal filter symbol lights up shows on the home appliance ### Kind of code Filters A filter has reached the end of its life or is clogged enough for the appliance to notice: a refrigerator water cartridge past its gallons or months, a hood's grease or charcoal filter loaded with residue, a dish-care filter packed with food, a washer inlet filter choked with grit. The fix is a clean or a new filter of the right part number, fitted with the appliance unplugged and the water closed where there is one, then the reminder reset. ### Usually leads to Water filter and descaling service Fresh filters in dispensers and ice makers, and scale cleared from steam ovens, ice makers and dish care machines. ### Shows up as Hood Fan Weak or Noisy: Grease Filters, Blower Wheel and Duct A hood fan that is weak or noisy pulls little smoke or steam off the cooktop, roars, rattles or whistles, often after months of cooking without the filters being cleaned. ### Make Miele Miele appliances tell you when they want care, from descaling prompts on steam ovens and coffee systems to filter reminders on the dishwasher and the dryer. ### Source Miele ventilation hood documentation Confirmed in Miele's ventilation hood documentation for recirculation-mode installations. ## Before you book, in this order.

Confirm the hood is running in recirculation rather than exhaust mode, since the charcoal filter only applies there. If it comes back, it needs a visit. ### Do I need a charcoal filter if my hood vents outside? No. Miele's documentation ties this filter to recirculation mode; a hood ducted outside relies on the grease filter and does not use a charcoal filter at all. ### How is the charcoal filter different from the grease filter? The grease filter is metal and washable; the charcoal filter is a consumable that Miele's own guidance says to replace rather than clean once its reminder appears. ### What happens if the charcoal filter is left in too long? It gradually stops absorbing odors from the recirculated air, so cooking smells linger in the kitchen even though the fan itself is still moving air normally. --- **[Read on the site: Miele hood — charcoal filter reminder](https://appliancemaintenance.center/error-codes/miele-hood-charcoal-filter/)** **[Book a visit with ApplianceMaintenance.center](https://appliancemaintenance.center/schedule/)**
