BoilerFaultCodesTechnical description
Fault burner
What causes this fault?
This fault occurs when the boiler's control system cannot detect a steady flame after trying to ignite. The most common reasons are a worn-out sensor that monitors the flame, a build-up of carbon on the sparking electrodes, or a fault with the gas valve that prevents fuel from reaching the burner.
This fault is frequently seen during the first cold snap of autumn when internal components that have been idle over summer fail to operate correctly under increased demand.
Engineer required
This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
