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)
12Ignition lockout. Check for gas or spark absence.If the ignition transformer is faulty, it does not generate a spark at the electrodes; the boiler does not detect a flame during the start-up time and locks with 12. Check by supplying power to the transformer (≈230 V) and verifying that it delivers high voltage to the electrodes or that there is an audible/visible spark.
60-70-90Ignition lockout (gas or spark may be missing).In models with LED signalling (RS), a faulty ignition transformer prevents sparking; the unit interprets a start-up fault and displays 60-70-90. Check for spark and measure/supply the transformer; if it does not deliver high voltage, replace it.
How do I know if this ignition transformer is for my boiler?
Verify the reference 122155360 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 ignition transformer generates the high voltage for the electrode spark.
Is there no spark or repeated ignition faults?
No spark at the electrode despite having gas.
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
Check the electrode and the high voltage cable.
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.
