BoilerFaultCodesTechnical description
Water pressure sensor fault
What causes this fault?
This fault occurs when the boiler's internal computer receives an incorrect or missing electrical signal from the water pressure sensor. The most common reason is that the sensor has become blocked with system debris or has suffered an electrical failure, preventing it from verifying that 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.
