BoilerFaultCodesYour boiler has stopped working because the water pressure inside the heating system has dropped too low.
Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.
Technical description: The PCB checks the pressure of the primary circuit, if the pressure measured is 0.8 bar or lower, the boiler will lockout after 40 seconds. The pump will stop.
DIY fix possible
Locate the external filling loop, usually a silver flexible hose connected to two valves beneath the boiler.Open the valves slowly to allow mains water to enter the system until the pressure gauge reads between 1.0 and 1.5 bar.Close both valves firmly and ensure no water is leaking from the connection points.
