What we can confirm
Code Flashing C on the display, from the manufacturer's own documentation
This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.

On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

It is on this page because it is what somebody is actually looking at when they go searching. Most of this maker's equipment publishes no code at all, and an appliance that flashes at you is still telling you something — it simply is not telling you a number.
People find this page looking for why the Bertazzoni range hood lights are flashing. They are not reporting a failure; they are reporting a filter interval.
What to do
- Wash the grease filters. They are metal and they go in the dishwasher.
- Replace the charcoal filters if the hood recirculates rather than ducts outside — charcoal cannot be washed or regenerated.
- Reset the alarm afterwards, or it goes on flashing at a hood with clean filters in it.
- This is the maker telling you to clean something, not the hood failing. A hood that is also pulling badly is a separate question and it is usually the ducting.
What the repair is
Conditions like this one end at Range hood ducting & airflow service more often than anywhere else. The figure on that page is a starting point; the exact cost is confirmed after an on-site diagnostic and agreed in writing before anything is opened.
