Your boiler has detected that the water pressure inside the system is currently too low to operate safely, causing it to shut down to prevent damage.

Call an engineer soon

Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.

Technical description: External safety interlocking tripped (e.g. low water pressure)
Typical repair cost £80-120 (including labour)

DIY fix possible

Locate the filling loop (usually a silver braided hose with one or two valves) connected to the boiler pipes.Gradually open the valve(s) to allow mains water into the system until the pressure gauge reads between 1.0 and 1.5 bar.Close the valve(s) tightly and restart your boiler.
