BoilerFaultCodesYour boiler is currently sitting in standby mode because it has reached its target temperature and is waiting for a new request for heating or hot water.
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: The boiler is on standby
What causes this fault?
This status occurs when the boiler has successfully heated your radiators or water cylinder to the required temperature and no longer needs to fire the burner. It acts as a pause state, where the system monitors for a drop in temperature or a new signal from your thermostat before restarting. There is physically nothing wrong with the appliance; it is simply waiting for the next instruction to provide heat.
DIY fix possible
Check if your room thermostat or programmer is set to a temperature higher than the current room temperature.Ensure the heating and hot water schedules are set to 'On' or 'Auto'.Wait a few minutes to see if the boiler fires up once the system temperature drops slightly.
