BoilerFaultCodesTechnical description
Flame Loss
What causes this fault?
This fault occurs when the boiler's control system can no longer detect the flame required to heat your water, causing it to shut down for safety. The most common reasons include a buildup of carbon on the sensing probe, a skip in the gas supply, or an internal component failing to provide a consistent spark.
This fault can be more frequent during the first cold snap of winter, as internal components that have been idle over summer may struggle 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.
