BoilerFaultCodesYour boiler is currently trying to light the gas burner and will stop flashing once it successfully senses the flame.
This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
Technical description: Flashes to indicate ignition operation (stops after detection).
What causes this fault?
This code appears when the boiler is actively trying to create a spark and light the gas burner. It is usually a temporary status message, but if it persists, it means the system is struggling to detect a stable flame due to a worn ignition lead or a dirty sensing probe. In some cases, it may also indicate that the gas supply is slightly delayed in reaching the burner.
DIY fix possible
Observe the light to see if it stops flashing and stays on or goes out as normalCheck that your gas supply is turned on at the meterIf the boiler fails to light after several attempts, try pressing the reset button
