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)
301EEPROM error (PCB memory).The auxiliary PCB EI A‑FFI/P (Ref. 952975) shows corruption or invalid reading of the EEPROM; check 5/12 V voltages and, if the fault persists after reset, replace the PCB.
302Communication error (internal bus/between PCBs).The EI A‑FFI/P (952975) loses internal communication between microcontrollers or with the interface; check connectors/wiring and stable power supply, and if it continues, replace the PCB.
303Main PCB fault.Internal fault of the EI A‑FFI/P (952975); after ruling out sensors/actuators and confirming 230 V and low voltages are correct, the recommended repair is to replace the PCB.
305Main PCB fault.Internal electronic fault in the EI A‑FFI/P (952975); if it reappears after reset and basic electrical checks, replace the PCB.
306Main PCB fault.Hardware anomaly in the EI A-FFI/P (952975) detected by self-diagnosis; confirm power supply/wiring and, if it persists, replace the PCB.
307Main PCB fault.Critical fault of the EI A‑FFI/P (952975) confirmed by the system; after basic tests, the usual action is to replace the PCB.
How do I know if this PCB is for my boiler?
Verify the reference 952975 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.
