What does the Keston E26 fault code mean?

Your boiler has started an ignition sequence but the flame keeps going out, meaning it cannot stay lit to provide heat or hot water.

How much does it cost to fix Keston error code E26?

Typical repair cost for the Keston E26 fault is £90-250 including labour.

Check the white plastic condensate pipe outside for signs of ice or blockages and defrost with warm water if frozen.

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).

This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
