Gaggenau's ventilation manual has the saturation display blink automatically after 30 hours of fan use, prompting a wash of the metal mesh grease filter. It is a scheduled reminder tied to run time, not a report of anything having failed. Gaggenau home appliance display What to do when Saturation display blinks 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 Gaggenau Gaggenau combi-steam ovens and built-in coffee machines ask for descaling on a schedule, and a visit also covers Vario cold storage and the dishwasher. ### Source Gaggenau AW 230-790 ventilation hood use and care instructions Confirmed in Gaggenau's AW 230–790 ventilation hood use-and-care instructions. ## Before you book, in this order.

Let the appliance cool, then remove the metal mesh grease filter for cleaning as the manual describes. If it comes back, it needs a visit. ### What does the 30-hour count on a Gaggenau hood actually track? The manual ties it to hours of fan operation, not to how greasy the filter looks, so the display can blink even in a kitchen that seems to cook lightly if the fan itself runs often. ### Can the saturation display be reset without cleaning the filter? The manual describes resetting it with the button while it is blinking, but the point of the reminder is the cleaning itself, so resetting without washing the filter defeats the purpose. ### Is a blinking saturation display urgent? No. It is a scheduled maintenance prompt, and the manual gives no separate warning about immediate risk; it should still be acted on promptly since a greasy filter is a fire risk over time. --- **[Read on the site: Gaggenau hood filter — saturation blink](https://appliancemaintenance.center/error-codes/gaggenau-hood-saturation/)** **[Book a visit with ApplianceMaintenance.center](https://appliancemaintenance.center/schedule/)**
