BoilerFaultCodesTechnical description
Pressure sensor fault
What causes this fault?
This fault occurs when the boiler's internal computer doesn't see a small 'jump' in water pressure that should happen every time the pump kicks in. The most common reasons are a sensor blocked with debris or a failing pump that isn't moving the water with enough force to be detected.
This fault is more frequent in autumn when the heating is first turned on after summer, as pump components can seize up during long periods of inactivity.
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.
