Your boiler has stopped working because it failed to light or stay lit, which has triggered a safety shutdown.
Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.
Technical description: FAULT POINT E. BURNER LOCKOUT. Gas supply problem, spark electrode/lead failure, gas valve failure, or flame sense electrode failure.
What causes this fault?
This fault occurs when the boiler tries to light the burner but fails to detect a stable flame after several attempts. The most common reasons are a lack of gas reaching the unit, worn-out spark components that can no longer create a flame, or a sensor that is too dirty to 'see' the flame once it has started.
DIY fix possible
Check if your gas supply is active and credit is on your meterPress the reset button once to see if the boiler restartsEnsure any external gas valves are in the open position
