BoilerFaultCodesYour boiler has lost its connection to the sensor that monitors water pressure, meaning it can no longer tell if there is enough water to run safely.
Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.
Technical description: Water pressure sensor open circuit
What causes this fault?
This fault occurs when the boiler's main computer loses electrical contact with the component that monitors water levels. The most common reason is a loose or damaged connection in the internal wiring, though it can also happen if the pressure sensor itself has suffered an internal electrical failure. Without this data, the boiler shuts down as a safety precaution to prevent it from firing while dry.
