E26 High
Your boiler is struggling to keep its flame lit, which often happens because the drainage pipe is blocked or frozen, or there is an issue with the air supply.
Technical description: Flame drop out – check for obstruction of the flue and/or air terminals, blockage/freezing of the drain pipe or a low gas supply (LPG).
Typical repair cost: £100-280 (including labour)
DIY fix possible
Check the white plastic condensate pipe outside for signs of ice or blockages.If frozen, gently pour warm (not boiling) water over the pipe to thaw it.Ensure the external flue terminal is not obstructed by debris or garden foliage.
