Quick answer
F03 · an airflow issue · Bertazzoni tumble dryer — independent summary for homeowners.
Model compatibility: Bertazzoni reuses codes across series and model years, so F03 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
Homeowners usually see F03 on a Bertazzoni tumble dryer in connection with a possible airflow or ventilation problem. Independent technicians still match the code to your serial family before ordering parts. Two Bertazzoni units can share a display string yet mean different subsystems; verify for your serial family.
