Worcester Bosch EA — what it means

No flame detected — the boiler tried to light but couldn't sense a flame, so it locked out for safety.

⚠ This is the likely cause from the code — a Gas Safe registered engineer confirms it on site. If you can smell gas, stop and ring 0800 111 999.

✅ Try these first — they're free

Often clears it without a callout:

  • Check other gas appliances work (so you know gas is on)
  • In cold weather, check the white condensate pipe outside isn't frozen — pour warm (not boiling) water over it
  • Press and hold the reset button for a few seconds — once only

🔧 If that doesn't fix it

The likely cause is one of these — the engineer confirms which:

  • Ignition electrodes worn or dirty
  • Faulty gas valve
  • Blocked or frozen condensate pipe
  • Flame-sense fault

Most likely part: Ignition electrode set

⚠ Worth knowing

  • Once the ignition is fixed, a tired gas valve or flame-sense electrode often shows up next — worth checking together
