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)
F1Ignition fault: the boiler does not establish a flame and goes into lockout.If the ignition transformer (spark generator module) does not deliver high voltage to the electrode, there is no spark or ionisation; check for the absence of audible/visual spark, inspect the HT cable and ground, and measure/test the transformer's output.
F4Ignition fault (retry or the flame goes out after ignition).A weak/intermittent ignition transformer generates an unstable spark and the burner does not stay on; check the spark during the retry, inspect high voltage wiring and connections, and confirm with measurement or replacement of the module.
How do I know if this ignition transformer is for my boiler?
