BoilerFaultCodesTechnical description
Summer/Winter function
What causes this fault?
This status occurs because the heating function has been manually deactivated or the outside temperature is high enough that the boiler's weather sensors have told it to stop warming the radiators. While the boiler will still provide hot water, it ignores any requests for central heating to save energy during warmer periods. It is an intentional setting rather than a mechanical failure or broken part.
This status is most common during the spring and summer months when homeowners turn down their thermostats or the boiler’s outdoor sensors detect warmer weather.
DIY fix possible
Locate the radiator symbol button on the control panel.Check if the heating temperature is set to 'Off' or a very low temperature.Increase the heating temperature setting to re-activate the central heating mode.
