Technical description
Water pressure sensor fault
What causes this fault?
This fault occurs when the boiler's internal electronic sensor can no longer accurately monitor the water pressure inside the system. The most common reason is that the sensor has suffered an electrical failure or has become blocked by debris and sludge build-up, preventing it from sending a reliable signal to the main control board.
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.
