BoilerFaultCodesThe 6 most common faults
Your boiler is unable to light the flame needed to heat your water or radiators, resulting in the system shutting down for safety.
Check if other gas appliances in your home (like a hob) are working to ensure your gas supply is onConfirm you have credit on your gas meter if you use a prepay systemPress the 'Reset' button on the boiler control panel for 3-5 seconds
Your boiler has got too hot and has shut itself down as a safety precaution to prevent damage.
Check that your radiator valves are open and not turned to zero.Ensure there is enough water pressure in the system (typically between 1 and 1.5 bar).Wait for the boiler to cool down and press the 'reset' button on the control panel.
Your boiler has shut down because its internal temperature has gotten too high and a safety switch has tripped.
Check that all radiator valves are fully openEnsure the system pressure is between 1.0 and 1.5 barAllow the boiler to cool down and try pressing the reset button
Your boiler has stopped working because the water pressure in your heating system is too low.
Locate the filling loop (usually a silver braided hose with small valves underneath the boiler).Slowly open both taps/valves until you hear water entering the system.Watch the pressure gauge and close the valves tightly once the needle reaches 1.5 bar.
Your boiler has detected that the water pressure in your radiators or pipework is too low for it to run safely.
Locate the filling loop (usually a silver flexible hose) underneath the boiler.Gradually open the black handles (one or two) to allow water into the system.Watch the pressure gauge and close the handles once the needle reaches 1.5 bar.
Your boiler has entered a safety lockout mode because it either failed to light properly or it has detected that the system is getting too hot.
Check that your gas supply is turned on and you have credit on your meter.Locate the selector switch and turn it to the 'R' (Reset) position for several seconds, then back to 'On'.Ensure your radiator valves are open and the system pressure is between 1 and 1.5 bar.
