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.73Water pressure sensor signal out of range (too low).The sensor 0020059717 may be faulty or shorted to ground, delivering a low signal; check 5/24 V and sensor wiring and compare the actual pressure (manometer) with the display reading.
F.74Water pressure sensor signal out of range (too high).Internal fault of the sensor 0020059717 or cable short to 5/24 V causes high signal; check the harness to the sensor for shorts and measure the sensor's power supply/signal.
F.75The pressure change is too low when starting the heating pump.If the sensor 0020059717 does not detect a pressure increase when the pump starts, the boiler locks out due to lack of water; check that the pressure reading changes at the pump start and compare with the pressure gauge.
F.22Installation pressure too low.A faulty sensor 0020059717 may report low pressure even if it is correct; verify the actual pressure with a manometer against that shown by the boiler and check the power supply/wiring of the sensor.
How do I know if this pressure sensor is the one for my boiler?
Verify the reference 0020059717 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.
