Technical description: Check water system for overheating or ignition failure
What causes this fault?
This fault happens when either the boiler’s internal temperature has exceeded safe limits or the burner has failed to light after several attempts. It is often triggered by a lack of water flow preventing heat from leaving the boiler, or an issue with the electrical spark that starts the flame.
This issue often appears during the first cold snap of autumn when a pump that has been sitting idle all summer fails to start up.
DIY fix possible
