Bertazzoni KG Hood Display: C blinking with F or C and F for filter service

What Display C flashing alternating with F / with C and F means

On Bertazzoni KG30X, KG36X and KG48X range hoods, the display item C flashes alternating with the letter F when the grease filters must be washed. When it alternates with C and F, the carbon filters must be replaced. Holding the B key for about 5 seconds resets the reminder. The owner sees the letters blinking while the hood continues to run.

Common causes of Display C flashing alternating with F / with C and F

Grease filters full after hours of use (C alternating with F)
Carbon filters at the end of life (C alternating with C and F)
Reminder not reset after cleaning

✓ One safe check you can try

1. Read which letters alternate on the display. 2. Take out the grease filters, wash them in warm soapy water and let them dry. 3. Swap the carbon filters for new ones if that is the message. 4. Refit the filters and hold B for about 5 seconds. 5. If the display still blinks, call us.

! Why to stop there

Clogged filters lower suction and raise fire risk.
Carbon filters must be the right model.
Wiring above the hood is live.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Display C flashing alternating with F / with C and FDisplay C flashing alternating with F / with C and F questions

What is the difference between the two patterns?

C alternating with F means wash the grease filters. C alternating with C and F means replace the carbon filters. Watch the letters for a few seconds to tell which one is showing.

How do I reset the display?

Hold the B key for about 5 seconds after the filter service. The letters stop blinking and the hood starts counting again toward the next reminder.

How often should I wash the filters?

Often enough that the reminder does not come up. Heavy frying or wok cooking means shorter intervals, and the display tells you when the time has come.
