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)
F1The burner does not ignite.If the gas valve is faulty or does not open, gas does not reach the burner and the boiler does not ignite; check the power supply to the valve during the ignition attempt and the continuity of its coils/modulator, as well as the upstream gas pressure.
F9There is no communication between the electronic equipment and the gas valve.A damaged gas valve (coil/modulator open or short-circuited) or its wiring prevents reading/control from the PCB and generates F9; check coil continuity, voltages/control signal, and the wiring harness; replace the valve if it does not operate with correct power supply.
