What can cause the Ideal F2 fault code?

Flame loss is a tough fault to diagnose without inspecting the unit but can often come down to one of the following:

  • Issue with the fan
  • Flue fault
  • Gas pressure at incorrect level
  • No gas supply
  • Failure of electrical components

While the above causes can be specific causes for flame loss, it's also worth asking a heating engineer to take a look at the PCB board. This is part of the unit that decides which error code to display so it's good to know that it isn't faulty.
