Bertazzoni KG hood: C and F alternating
In a recirculating installation, the charcoal filters last longer between changes than the grease filters, so the hood tracks them on a separate interval and asks for both a filter swap and a grease-filter wash at the same time.

What to do when C F shows on the home applianceKind of codeFilters
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.

Fresh filters in dispensers and ice makers, and scale cleared from steam ovens, ice makers and dish care machines.

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.

Bertazzoni upkeep is mostly about the range: burner caps and ports, the oven gasket and the hood above, with the matching refrigerator and dishwasher checked in the same trip.

Before you book,
in this order.
Each step comes from Bertazzoni's own guidance for C F on its home appliances. Follow it to the end: the last card says whether this is a visit.
Remove and wash the grease filters as usual.
Fit new charcoal filters from the kit listed for the specific KG model; they cannot be washed and reused.
With everything back in place, hold button B for about five seconds until the display stops flashing.
Book a visit if the alternating C and F pattern returns within a few days.
Still there?
It usually turns into water filter and descaling service. Book with the code and the model number.
What not to do
This reminder is only relevant on a hood set up to recirculate air; a ducted hood has no charcoal filters to change. A steady C with the motor off is a different message, the hood's clean-air mode, not a filter request.

In Bertazzoni's own words
When display item C flashes, at a speed where it alternates with the letter C and F, the carbon filters must be replaced.
