BoilerFaultCodesTechnical description
Water pressure sensor error (short circuit or open circuit)
What causes this fault?
This fault occurs when the boiler's internal computer loses communication with the sensor that monitors water levels. The most common reason is that the sensor's internal electrical components have failed or the wiring connecting it to the main control board has become loose or damaged. Because the boiler cannot verify that it has enough water to operate safely without this sensor, it shuts down to prevent overheating.
Engineer required
This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
