Keston Boilers Guide

Hi,

My Keston combi C36 boiler is giving a tough time from last two days as it shows the L2 error code. Restarting is also not working. I have tried every possible thing but no progress. Someone, please tell me what does L2 means & how I can fix it at home?

Thank you so much

Hello, here L2 means “Flame Loss”. It means that the boiler’s burner is not igniting or even failed to remain alight. Several different components of the boiler can cause it such as dirty/muddy spark electrode & ionization probe. Moreover, clogged condensate trap can also cause flame loss. If other appliances in your home are also not working then you have to check the gas supply. In case the problem persists, you can call an expert engineer to rectify it.
