What causes this fault?

This code is not actually a fault, but a status indicator showing that your boiler is powered on and functioning correctly. It physically signifies that the system is in standby mode and is simply waiting for a signal from your thermostat or a hot water tap to begin firing. No internal components have failed, and the boiler is ready to operate as soon as there is a demand for heat.

DIY fix possible

Check that your room thermostat is turned up high enough to call for heatEnsure your programmer or external timer is set to an 'On' periodVerify that the boiler power switch is in the 'On' or 'Auto' position
