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 appliance

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.

01

Remove and wash the grease filters as usual.

02

Fit new charcoal filters from the kit listed for the specific KG model; they cannot be washed and reused.

03

With everything back in place, hold button B for about five seconds until the display stops flashing.

04

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.

Where C F usually leads

Water filter and descaling service.

Water filters replaced and flushed, inlet screens checked, descaling run on a steam oven, ice maker or dish care machine · low.

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.

Questions
about C F.

Can I clear C F myself?
Remove and wash the grease filters as usual. If it comes back, it needs a visit.
Can the charcoal filters from a Bertazzoni KG hood be washed?
No, they are a replace-only part; washing them ruins the charcoal and they still need swapping.
How often does a Bertazzoni KG hood typically need new charcoal filters?
Less often than grease filters, with the manuals putting the interval at roughly every four months of typical use.
Why does my ducted Bertazzoni hood still ask for charcoal filters?
The control can keep counting for this reminder even without charcoal fitted; clearing it with button B is the fix, and a repeat prompt is worth a visit to check the setup.

Back to your everyday

Still showing C F?

A booking goes further when it has the reminder or code as shown, the model number from the rating plate, and a word on when that filter, screen or tub was last cleaned. With those three, the office can pack the right filter or cleaner for your appliance.
