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)
F 04Flame not detected at the end of ignition or parasitic flame reading.The PCB 6301470 manages ionization detection; if its circuit loses "visibility" of the flame or misinterprets it, it triggers F 04. Check ionization microamperage, ground/electrode, and continuity to the PCB; if the signal is correct and the fault persists, the detection circuit of the PCB is damaged.
F 09Sealed/open configuration anomaly.The PCB reads this configuration through the X15 card connector; incorrect wiring/incoherent reading in X15 causes F 09. Check pinout and continuity of the harness in X15 and the coherence of the configuration; if correct and persists, check the reading input/PCB.
How do I know if this PCB is for my boiler?
Verify the reference 6301470 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Sime 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.
