BoilerFaultCodesYour boiler is currently running its fan to clear out any remaining heat or gases after it has stopped firing, which is usually a normal part of its operation.
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: Post-purge
What causes this fault?
This code appears when the boiler has finished heating and needs to clear excess heat or leftover flue gases from the internal combustion chamber. It is a standard safety process where the fan continues to spin for a short period after the burner has turned off. As long as the code clears itself after a few minutes, your boiler is operating exactly as it should.
DIY fix possible
Wait for several minutes to see if the code clears automaticallyCheck that your room thermostat is not set higher than the current room temperatureReset the boiler if the code persists for more than 15 minutes without the boiler restarting
