BoilerFaultCodesYour boiler is working correctly and is currently resting because it has already reached the desired temperature or the thermostat is turned down.
This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
Technical description: Standby (no demand for heat)
What causes this fault?
This status occurs when the boiler has successfully heated your home to the level set on your thermostat and is now sitting in a ready state. It is not actually a fault, but rather the boiler's way of saying it is waiting for the temperature to drop before it fires up again. If your radiators are cold and this code is showing, it usually just means your room thermostat or programmer is turned off or set too low.
This code is frequently seen during the summer months when the heating is turned off and the boiler is only waiting to provide hot water.
DIY fix possible
Check that your room thermostat is turned up high enough to call for heatEnsure your programmer or heating timer is set to an 'ON' periodCheck if your hot water cylinder thermostat is satisfied
