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)
E20EVG lockout (hardware fault in the gas valve control).The control board governs the EVG through a relay/power stage; if that stage of the PCB fails, the unit detects an EVG lockout. Verify by measuring the output from the PCB to the valve (voltage/activation of the relay or triac) and continuity of the coil; if it does not switch with the correct command, replace the board.
E21EVG lockout (control relay fault of the valve).The control relay of the EVG is integrated into the PCB; if its contacts/coil fail, the boiler goes into lockout. Check the relay activation from the board (voltage on the coil, continuity, and contact closure under command) and, if it does not operate with the correct signal, replace the PCB.
E89Internal error (usually hardware) or issues with the electrical network.Indicates an internal fault in the electronics (power sources, microcontroller, or drivers) of the PCB; after ruling out the network (correct voltage and frequency), if it persists, the cause is the PCB. Verify by measuring voltages on the PCB and conducting a test with a known good PCB.
E99Card (PCB) not configured.Replaced PCB or loss of parameter settings; requires configuring the board (e.g., parameter P01/model). Check by entering the parameter menu and completing the coding; if it does not accept configuration or returns to E99, the installed PCB is incorrect or defective.
How do I know if this PCB is for my boiler?
Verify the reference BI1995100 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Bertelli Y Partners piece (HDIMS08-SA01).
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?
After ruling out mains voltage, fuse, and connectors, a damaged PCB causes lockouts, blackouts, or erratic display. Repair the external cause before installing the new one.
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.
