06
Low water pressure High DIY-safe

Your boiler has stopped working because the water level inside the system has dropped too low and needs topping up.

What to try first

Locate the filling loop (usually a silver flexible hose) underneath the boiler.Slowly open the one or two taps on the loop until you hear water flowing.Watch the pressure gauge on the screen until it reaches 1.5 bar, then close the taps tightly.
