Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.
Technical description: No water in the boiler or the pump is not working
DIY fix possible
Locate the filling loop (usually two silver taps connected by a braided hose) underneath the boiler.Gradually open the taps to let mains water into the heating system until the pressure gauge reads between 1.0 and 1.5 bar.Close both taps tightly and check the display to see if the error has cleared.
