Keston Combi C36 boiler not firing up

Hi All,

I have installed a Keston Combi C36 boiler three years ago. It worked well but now the boiler is not firing up. I am facing this problem from last few days. I have restarted it several times but there is no noticeable difference. What should I do? Someone please guide me

Thanks In Advance


Hi James,

If your Keston Combi C36 boiler is not firing up properly then, surely the fan is faulty. You will see an E05 error code on your Keston C36 boiler. Unluckily, this is not a matter of a DIY fix. Moreover, do not try to fix the problem at home. For this, you have to contact a skilled Keston boiler engineer, as he will be in better position to diagnose an issue with the boiler’s fan. In case, fan needs replacement, go for it to prevent further loss.
