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)
E20EVG lockoutThe EVG (gas valve) does not open/close correctly or does not receive the control signal. Check voltage at the valve connectors, continuity of coil/wiring, and pressure at the burner during the ignition attempt.
E21EVG lockoutGas solenoid valve fault or its control (coil/wiring), preventing gas supply. Check power supply to the EVG, coil resistance, and that there is a pressure variation at the test point when ignition is commanded.
E22EVG lockoutMalfunction of the electronic gas valve or absence of control signal from the PCB. Check control signal to the EVG, continuity of the EVG harness, and mechanical operation of the valve (opens/closes) with a manometer at the burner connection.
E23EVG lockoutLockout due to fault in the gas solenoid valve or its wiring, preventing gas flow to the burner. Check power/ground in EVG, wiring continuity, and pressure response at the burner connection when ignition starts.
