This boiler uses LED flash patterns

Count the flashes in one repeating group before the pause. That number is your fault code. Do not reset until you have noted it. How to read fault codes →

green light flashes rapidly

Your boiler is attempting to start but failing to stay lit, which means it cannot provide heat or hot water reliably. This is likely due to the system detecting a failure in the ignition process.

High Engineer only £150-300

Parts commonly replaced

  • Ignition electrode
  • Gas valve
  • Printed Circuit Board (PCB)

Green light flashing slowly

Your boiler is currently waiting for a signal from your heating controls, meaning it does not know that you want the heating or hot water turned on.

High Engineer only £120-250

Parts commonly replaced

  • Programmer
  • External Wiring
  • Room Thermostat
Lockout (Rapid Flashing Red)

Your boiler has failed to start after several attempts and has switched itself off for safety, usually because it cannot detect a flame or is struggling to get fuel.

High Engineer only £120-250

Parts commonly replaced

  • Ignition electrode
  • Gas valve
  • Printed circuit board (PCB)
Red LED: FLASHING

Your boiler has detected that it is getting too hot and has automatically shut down to prevent damage or dangerous overheating.

High Engineer only £150-300

Parts commonly replaced

  • Overheat thermostat
  • Pump
  • Circulation diverter valve
  • PCB
red light flashing

Your boiler has failed to start after several attempts because it cannot detect a flame, so it has purposefully shut itself down for safety.

High Engineer only £150-300

Parts commonly replaced

  • Ignition electrode
  • Gas valve
  • PCB
All lights OFF

Your boiler has lost all power and is completely unresponsive, meaning it cannot provide heating or hot water until the electrical connection is restored.

High Engineer only £120-250

Parts commonly replaced

  • Internal fuse
  • Printed Circuit Board (PCB)
  • Wiring harness
Blocking

Your boiler has switched itself off because it has detected an issue with its internal safety sensors or the electrical supply, and it needs a professional to investigate the cause.

High Engineer only £120-250

Parts commonly replaced

  • Air Pressure Switch
  • Fan Assembly
  • PCB
Earth Fault or Mains Reversal

Your boiler has detected an issue with its electrical supply, meaning it cannot safely start up or operate your heating system.

High Engineer only £120-250

Parts commonly replaced

  • Electrical PCB
  • Wiring harness
  • External fused spur
Lockout

Your boiler has stopped working because it couldn't safely ignite the flame after three attempts, often caused by a blockage in the gas supply or an issue with the air intake.

High Engineer only £120-250

Parts commonly replaced

  • Ignition lead
  • Spark generator
  • Gas valve
  • PCB
Mains ON Only

Your boiler has detected an internal fault that is preventing it from firing up, meaning you currently do not have heating or hot water.

High Engineer only £150-300

Parts commonly replaced

  • Printed Circuit Board (PCB)
  • Gas Valve
  • Electrode assembly
