Ideal Boiler L2 Fault Code: What It Means and What to Do

· 2 min read

Ideal boiler L2 fault code guide: a gas flame, with the L2 ignition lockout code

L2 on an Ideal boiler, such as the Logic, Logic+ or Vogue, is an ignition lockout. The boiler has tried to light and has not detected a flame, so it shuts down for safety.

Why does L2 appear?

  • No gas getting to the boiler, often a prepayment meter out of credit or a closed gas valve
  • A frozen or blocked condensate pipe in cold weather
  • A faulty ignition electrode or flame sensor
  • A faulty gas valve
  • A control board fault

Checks you can make

  1. Check another gas appliance in the house works.
  2. Check your gas meter has credit, if it is a prepayment meter.
  3. Make sure the gas valve under the boiler is open.
  4. In freezing weather, thaw the condensate pipe outside with warm (not boiling) water.
  5. Reset the boiler once. On many Ideal models you turn the mode knob to the reset position for a few seconds. Your manual shows the exact method for your model.

If L2 comes back straight away, do not keep resetting it. There is a fault that needs an engineer.

Getting it repaired

Ideal boilers are among the most common in Kent homes, and our engineers repair them every week. We test the electrode, gas valve and flame sensing, explain what has failed and price the repair before we start.

If you can smell gas, do not touch any switches. Turn off the gas at the meter, open windows, leave the property and call the National Gas Emergency Service on 0800 111 999.
