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)
C7No fan speed signal.The fan/extractor does not deliver the tachometer signal to the Heatronic (motor/rpm sensor or wiring). Check by measuring the speed signal at the fan connector and the power supply/continuity.
C6The pressure switch does not close.If the fan does not start or does not generate sufficient depression, the differential pressure switch does not close and the boiler locks out. Check that the fan rotates and reaches rpm and measure the depression at the pressure switch ports with a U-tube manometer.
CATurbine revolutions too high.The fan operates above the allowed range (fault of the motor itself/rpm control) and the Heatronic detects overspeed. Verify the tachometer signal and the control–rpm correlation according to service values.
C1The pressure switch has activated during operation.Flow drop or intermittent fan stoppage causes the pressure switch to open during operation. Check the fan's consumption and rpm under load and rule out obstructions/friction in the extractor group–chimney.
