The 6 most common faults
Your boiler has stopped working because it cannot light the flame or the internal drainage pipe is backed up with water.
Check if your shared external white drainage pipe is frozen or blocked.If frozen, pour warm (not boiling) water over the pipe to clear the ice.Press the reset button once to see if the boiler restarts.
Your boiler has shut down because a safety sensor has detected that the system is starting to overheat.
Ensure all radiator valves are fully openCheck that the system water pressure is between 1.0 and 1.5 barSwitch the selector dial to the reset position for five seconds and release
Your boiler is struggling to circulate water, which is usually caused by the system pressure being too low or a problem with the internal pump.
Check the pressure gauge on the front of the boiler; it should be between 1.0 and 1.5 bar.If the pressure is too low, use the filling loop underneath the boiler to top it up.Reset the boiler by turning the selector switch to 'R' for five seconds.
Your boiler is struggling to light or cannot keep the flame burning, which has caused it to shut down for safety.
Check that your gas pre-payment meter (if applicable) has credit.Verify that other gas appliances, like a cooker, are working to ensure gas supply exists.Reset the boiler by turning the selector switch to 'R' for at least five seconds and then back to the desire setting.
Your boiler has stopped working because water is not moving through the system properly or there is not enough water inside it.
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 filling loop to top it up.Ensure all radiator valves and isolation valves are fully open.
Your boiler has detected that water isn't moving through the internal pipes effectively, which prevents it from heating up safely.
Check that the boiler pressure is between 1.0 and 1.5 bar on the gaugeOpen any radiator valves that are turned off to ensure water can flowEnsure the main stop tap and any isolation valves under the boiler are fully open
