BoilerFaultCodesYour boiler is working correctly but is currently sitting idle because it hasn't been told to turn on by your thermostat or heating controls.
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: there is no heat demand from control system.
What causes this fault?
This code appears when the boiler is powered on and ready to work, but it is waiting for a signal from your thermostat or timer to start heating. Essentially, the boiler is 'asleep' because your heating controls have told it that the house is already at the desired temperature or that the heating is scheduled to be off.
This is more frequently noticed during the transition into spring or autumn, as homeowners begin to adjust their thermostat schedules and temperature settings.
DIY fix possible
Check that your room thermostat is turned up higher than the current room temperature.Ensure your programmer or heating clock is set to an 'ON' period.Check if any external batteries in your wireless thermostat need replacing.
