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)
F.22Safety shutdown: water shortage.The pressure sensor (050603) may send a reading of pressure that is too low even if the circuit is correct, triggering the safety. Verify by comparing the manometer with the digital reading and check the sensor's power/signal (e.g., autotest S.97 or measurement in harness).
F.73Fault: water pressure sensor not connected or short-circuited.Collector fault (open/short) or wiring causes invalid pressure signal. Check continuity and polarity of the harness, supply voltage (5/24 V), and sensor reading in diagnostics.
F.74Error: electrical problem with the water pressure sensor.Short circuit at 5/24 V in the harness or internal fault of the sensor generates a pressure signal that is too high/erroneous. Check voltages and replace the sensor if it does not deliver a plausible signal.
F.75When the pump starts, a sufficient pressure increase is not detected.If the pressure sensor is faulty/stuck or does not detect the pressure increase at the start of the pump, it triggers F.75. Check the circuit bleed and ensure that the sensor reading changes when the pump starts and matches the pressure gauge.
How do I know if this pressure sensor is the one for my boiler?
Verify the reference 050603 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 sensor measures the water pressure of the circuit for the electronics.
Pressure fault even though the pressure gauge reads correctly?
The sensor is not transmitting the correct pressure to the PCB.
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 connector and the gasket.
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.
