Miele's own ventilation documentation lights the grease-filter symbol on a default schedule of every 30 hours of use, prompting the owner to wash the metal filters before grease has a chance to build up. Miele home appliance display What to do when Grease 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; default interval is 30 hours of use and can be adjusted in some models. ## Before you book, in this order. Each step comes from Miele's own guidance for Grease filter symbol lights up on its home appliances. Follow it to the end: the last card says whether this is a visit. 01 Remove the metal grease filters once the appliance has cooled. 02 Wash them by hand or in a dishwasher as the appliance's own instructions allow, then dry and refit them. 03 Reset the symbol using the control described in the manual once the filters are back in place. ### Still there? It usually turns into [water filter and descaling service](https://appliancemaintenance.center/services/water-filter-and-descaling-service/). Book with the code and the model number. ### What not to do The symbol is a scheduled reminder, not a report that the fan or motor has failed. A hood that still moves little air with clean, correctly fitted filters points to the fan itself rather than the filter. ## What you may notice with it.

Remove the metal grease filters once the appliance has cooled. If it comes back, it needs a visit. ### Can the 30-hour default be changed? Miele documents this as a default interval, and some control panels allow adjusting it; check the specific model's own instructions before assuming it can be changed. ### What happens if the grease filter symbol is ignored? Grease keeps collecting in the filter, which reduces how much air the hood can pull and adds a fire risk over time, so the reminder is worth acting on close to when it appears. ### Is the grease filter the same part as the charcoal filter? No. Miele documents them as two separate reminders and two separate parts: a metal grease filter that is washed, and a charcoal filter for recirculation models that is replaced rather than washed. --- **[Read on the site: Miele hood — grease filter reminder](https://appliancemaintenance.center/error-codes/miele-hood-grease-filter/)** **[Book a visit with ApplianceMaintenance.center](https://appliancemaintenance.center/schedule/)**
