BoilerFaultCodesThe 6 most common faults
Your boiler has failed to light, which means your heating and hot water will not work until the system is reset or repaired.
Locate the reset button or dial on the front control panelPress or turn to 'Reset' for several seconds, then releaseCheck if your gas prepay meter has credit and that the main gas lever is open
Your boiler has detected that there is not enough water pressure or flow to operate safely, which is preventing your heating and hot water from working.
Check the pressure gauge on the front of the boiler; it should be between 1 and 1.5 bar.If the pressure is too low, use the external filling loop to top up the system with water.Reset the boiler once the correct pressure is reached to see if the fault clears.
Your boiler has likely overheated or a safety sensor has detected an incorrect temperature, causing it to shut down for safety.
Locate the reset button or control knob on the front panelPress and hold the reset button for five secondsCheck that your radiator valves are open and that the system pressure is between 1 and 1.5 bar
Your boiler has detected that there is not enough water in the system to operate safely, which has caused it to shut down.
Locate the filling loop (usually a silver braided hose) underneath the boiler.Open the small valve or valves on the loop slowly until you hear water entering.Watch the pressure gauge until it reaches between 1 and 1.5 bar, then close the valves tightly.
Your boiler has become too hot and has shut itself down as a safety precaution to prevent damage.
Check that all radiator valves are fully openEnsure your system water pressure is between 1 and 1.5 bar on the gaugePress the reset button once the boiler has cooled down
Your boiler's internal computer has encountered a glitch or software malfunction that is preventing it from running properly.
Locate the reset button on the boiler control panel.Press and hold the reset button for 5 seconds, then release.Wait for the boiler to restart; if the code persists, a professional repair is required.
