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 ignite).The SIT gas valve 05727100 does not open or is poorly regulated, and gas does not reach the burner at startup. Check the power supply to the EV coils during the spark phase and input/output pressures with a manometer; if a signal is received and it does not open or is unstable, adjust/replace the valve.
F4Ignition fault/flame disappeared after ignition.The gas valve opens with insufficient flow or closes prematurely, and the flame is lost shortly after ignition. Check the control voltage at the EV during and after ignition and adjust the SIT minimum/maximum; if it does not maintain a stable flow, replace it.
