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)
F37Incorrect water pressure in the installationIf the pressure switch/water pressure sensor gives a low reading or does not switch, the PCB interprets it as low pressure. Verify by comparing the pressure gauge with the state of the pressure switch, checking continuity/wiring, and, if necessary, replacing the part.
F47Water pressure sensor anomaly in the installationElectrical fault of the pressure switch/sensor (open circuit or interrupted wiring) prevents pressure reading by the PCB. Check with a multimeter for power/signal and continuity to the control board; if it does not switch with correct pressure, replace the pressure switch.
How do I know if this pressure switch is for my boiler?
Verify the reference I39818260 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.
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.

Installation and recommendations
Check the tightness of the pressure pipes and the switching of the contact.
