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 pressure switch has activated during operation.The differential pressure switch opens during operation due to a fatigued diaphragm or intermittent microcontact, causing the signal to be lost to the Heatronic. Check the continuity of the pressure switch while the fan is running and measure the depression/differential with a manometer on the sampling tubes.
C4The pressure switch does not open in the rest position.The pressure switch remains stuck/closed at rest due to mechanical failure or residual pressure in the connections. With the fan stopped, verify that the contact is open and that there is no water column/obstructions in the tubes; check with a multimeter and manometer.
C6The pressure switch does not close.The pressure switch does not switch to closed when the fan starts due to internal misalignment or a damaged diaphragm, preventing combustion authorization. Verify that when the fan starts, the contact closes (continuity test) and that the achieved depression exceeds the pressure switch threshold (measurement at ports).
How do I know if this pressure switch is for my boiler?
Verify the reference 87167711750 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Huba piece.
What is it used for?
The pressure switch controls the pressure/draught (of air in sealed systems) or water to authorize operation.
Is the boiler not starting or showing a draught fault?
If the fan spins but does not ignite, check the pressure tubes (loose/blocked), the diaphragm, and the fan.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
Check the tightness of the pressure pipes and the switching of the contact.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
