How do I know if this pressure switch is for my boiler?

Verify the reference 39806180 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.

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.

What does the F8 code mean on Ferroli?

Insufficient water pressure in the heating system. The water pressure switch (I39806180) does not close due to low actual pressure or mechanical/electrical fault; check pressure on the gauge (≥0.8–1.5 bar), continuity of the pressure switch and its wiring/terminal connections.
