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)
06Overtemperature open during ignition.If the circulating pump is seized/not rotating, there is no circulation in the primary circuit and the heat exchanger overheats on start-up, activating the safety clixon. Check by loosening the shaft from the front plug of the pump and verifying that it receives voltage and consumes/starts rotating.
14Overtemperature open during operation.A blocked or failing circulating pump reduces the flow during service and causes overheating of the primary, triggering the klixon. Check the actual rotation of the rotor from the plug, electrical supply, and bleed air from the circuit in case of cavitation/air pockets.
