What causes this fault?

This is a normal operational status and not a mechanical fault or failure. It appears when your thermostat or programmer has requested warmth, signaling the boiler to ignite the burner and circulate hot water to your radiators. You may see this code frequently during colder periods as the system works to maintain your target indoor temperature.

You will see this code more regularly during the autumn and winter months when your central heating is scheduled to be active.
