BoilerFaultCodesYour boiler is working perfectly and is currently sitting on standby because your heating and hot water are already at the desired temperature.
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 appears when your boiler is operating correctly and has simply reached the temperature set on your thermostat or internal settings. It means there is currently no request for heating or hot water, so the boiler has paused its firing process to save energy while it waits for the temperature to drop. This is a normal part of the boiler's cycle and indicates that the system is ready to work as soon as it is needed.
This display code is seen more frequently during the summer months when the central heating is turned off and the boiler only fires occasionally for hot water.
DIY fix possible
Check if your room thermostat is turned up high enough to trigger a demand for heatEnsure your heating programmer or timer is set to an 'on' periodRun a hot tap to see if the status code changes to signify hot water production
