BoilerFaultCodesThe 6 most common faults
Your boiler has shut down because the internal heat exchanger is getting too hot, usually caused by poor water circulation or trapped air.
Check that your system water pressure is between 1.0 and 1.5 bar on the pressure gauge.Ensure all radiator valves are fully open to allow water to flow through the system.Gently bleed your radiators to remove any trapped air that could be blocking circulation.
Your boiler is failing to light the gas flame, meaning you have no hot water or heating.
Check if other gas appliances in your home are working to ensure gas is being supplied.Press the 'Reset' button on the boiler control panel to clear the temporary error.Ensure your pre-payment gas meter has sufficient credit.
Your boiler is failing to stay alight after it tries to start up, meaning it cannot provide heat or hot water.
Check that your gas supply is turned on at the meterCheck if other gas appliances in your home are workingPress the 'Reset' button on the boiler control panel
Your boiler has sensed that the water inside is getting too hot and has shut itself down to prevent damage.
Check that all radiator valves are fully open to allow water to circulate.Ensure there is enough pressure in the system by checking the gauge (it should be between 1 and 1.5 bar).Try resetting the boiler by pressing the 'Reset' button.
Your boiler has sensed that the water returning to the unit is too hot, causing it to shut down for safety.
Check that at least two or three radiator valves are fully openEnsure the central heating system pressure is between 1.0 and 1.5 barPress the reset button on the boiler control panel
Your boiler has stopped working because the water pressure inside the system has dropped too low.
Locate the filling loop (the flexible silver hose) underneath or near the boiler.Open the small black taps on the filling loop slowly until you hear water entering the system.Watch the pressure gauge on the boiler display and close the taps once it reaches 1.5 bar.
