Bertazzoni range hood: A flashing key on a KPH hood — and the rate is the message
Bertazzoni range hood — an indicator rather than a code. The same alarm on a different control, and the flash rate is what distinguishes the two filters: the A key flashing about every two seconds means the grease filters must be washed; flashing about every half second means the active carbon filters must be replaced.

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.

About Bertazzoni range hood: A flashing key on a KPH hood — and the rate is the message
This is an indicator, not an error code
The same alarm on a different control, and the flash rate is what distinguishes the two filters: the A key flashing about every two seconds means the grease filters must be washed; flashing about every half second means the active carbon filters must be replaced.
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.
This is the alarm behind most searches for the Bertazzoni range hood filter: the appliance is counting hours and asking for one of two filters, and the flash rate says which.
What to do
- Watch the rate rather than the fact of it flashing — slow is grease, fast is charcoal.
- Wash the grease filters; replace the charcoal ones if the hood recirculates.
- Reset by holding the A key for about five seconds until it stops flashing.
What the repair is
