Keston Combi C36 boiler error code L6


I have purchased a Keston Combi C36 boiler three years ago. I have not confronted any mentionable issue but now I want to seek help from experts as the boiler is not responding and displaying a L6 error code since last two days. Please guide me

Thanks for your suggestions


Hi Robert, L6 error code means, “False flame lockout”. You should try resetting the boiler by following the resetting instructions. In case, it does not work for you, do contact a Keston Boiler service center if the boiler is under warranty. Conversely, if the boiler is not under warranty you call a skilled boiler engineer for immediate help. I hope that this information will help you. Feel free to contact us for further help
