Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
Er20EVG lockout (hardware fault).Fault in the EVG circuit on the main PCB (driver/relay/triac that controls the gas valve). Check by measuring the EVG output on the PCB during demand and ruling out wiring and gas valve.
Er21EVG lockout (hardware fault).Fault in the EVG channel on the PCB (e.g., relay/power stage for valve control). Check activation/continuity of the EVG relay on the board and ensure the valve receives a signal with the correct wiring.
Er22EVG lockout (hardware fault).Internal defect in the EVG electronics of the PCB causing anomalous detection and lockout. Verify EVG control signals on the PCB and rule out ionization/valving and wiring issues.
Er99Card not configured.Main PCB unparameterized after replacement or loss of configuration. Verify by entering programming mode and configuring the model (parameter P01/Pr01) according to the manual; after coding, the error should disappear.
How do I know if this PCB is for my boiler?
Verify the reference BI2445100 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Biasi part.
What is it used for?
The PCB controls the ignition, modulation, sensor readings, and safety features of the boiler.
Is the boiler not igniting, locking out, or is the control board unresponsive?

Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
After installation, a technician must adjust the service parameters (type of gas, power settings) and check combustion and safety features.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
