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)
20Gas valve error '1' (the flame persists for 15 s after the V1 closure command).The multigas valve (SIT Sigma 848) gets stuck or leaks in path 1: even though the PCB cuts the command, combustion continues. Check for absence of voltage in the V1 coil and persistence of flame/flow at the test point; if confirmed, replace the valve.
21Gas valve error '2' (the flame persists for 15 seconds after the V2 closure command).The multigas valve (SIT Sigma 848) does not close path 2 and the gas continues to pass after the command is cut. Verify that the V2 coil is not receiving voltage and that the flame/flow continues; if confirmed, replace the valve.
