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)
C1The differential pressure switch has been activated during operation.The extractor (flue fan) stops or rotates too slowly during operation and causes the pressure switch to change state; check the power supply and rpm signal of the fan, differential pressure of the pressure switch, and tubes/venturi.
C6The differential pressure switch does not close.The extractor does not generate sufficient flow/vacuum (fan too slow) and the air pressure switch does not close; check the fan speed/power supply and the closing of the pressure switch by measuring the differential pressure and inspecting the exhaust duct.
C7The fan is not working.Fault in the extractor (motor/RPM sensor/wiring) prevents its rotation or speed signal; check for 230 V supply and tachometric signal to the fan, continuity, and that the impeller rotates freely.
