BoilerFaultCodesTechnical description
Water pressure sensor fault
What causes this fault?
This fault occurs when the internal electronic sensor responsible for monitoring water pressure fails to send a reliable signal to the boiler's main control board. The most common reason is an electrical failure within the sensor itself or loose wiring, which prevents the boiler from confirming there is enough water to operate safely.
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.
