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)
A97Shutdown due to a fault in the operating logic.Internal fault of the CMP3‑MCU PCB (monitoring/firmware) causing the board itself to lock the equipment. Check voltages 230 V/5–12 V on the board, grounds, and connectors, reseat the EEPROM key; if it persists, replace the board.
A98Shutdown due to a fault in the operating logic.Electronic control/monitoring anomaly in the main PCB (CMP3‑MCU): logical or reading inconsistencies cause the PCB to stop the boiler. Check power supplies, connectors, and EEPROM key; if not corrected, the PCB is defective and must be replaced.
A99Shutdown due to a fault in the operating logic.Logic/electronic monitoring error managed by the CMP3‑MCU board; the boiler goes into lockout due to an internal PCB fault. Check voltages and connections of the board and EEPROM; if it persists after checks, replace the board.
How do I know if this PCB is for my boiler?
Verify the reference 65101732 printed and ensure your model is on the list of compatible ones; also compare the connections with the original 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?
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.
