Common Ideal Boiler Error Codes & Faults

Just like most types of boilers, some boiler problems crop up more often than others, so we’ve focussed on the most common faults in this section.

For more help in working out what the issue might be, check out our troubleshooting guide to when your boiler’s not working.

How to fix an F1 error code

The Ideal boiler F1 error code is displayed on the control panel when your system has low water pressure.

This is a simple issue to fix yourself and just needs the water level topping up in the boiler. We’ve provided more guidance in our article on what to do when your boiler has a pressure that is too high or too low.

How to fix an L2 fault code

The Ideal boiler L2 fault is displayed when the flame has gone out on your system. There are a number of different reasons as to why this might be happening, which include:

  • Reduced gas pressure
  • The flue becoming blocked
  • A gas valve becoming faulty
  • Faulty flue sensor

This then means that the boiler then goes into lockout mode to ensure your safety. As a result, you’ll then need to call out an engineer who can establish the reason for the fault, carry out the repair and then reset the boiler for you.

To avoid the stress of unexpected repair bills, boiler cover can be a great way of ensuring that you can get repairs done without big bills.

How to fix an F2 fault code

The Ideal boiler F2 error code is also displayed when the flame has gone out. So, just as with the Ideal Logic L2 fault code, this is going to mean that your boiler has gone into lockout. It will now need to be seen by a qualified gas technician to get everything up and running again.

How to fix an L9 fault code

The Ideal Logic L9  error code means a problem with the printed circuit board (PCB).  This might mean that it’s no longer configured correctly to operate the boiler, or it might have developed a fault. Unfortunately, either way, it’s going to need the visit of a gas technician to sort out the problem.

Summary

ideal boilers fault codes

Thankfully some issues, such as the Ideal Logic F1 code, can be fixed by the homeowner. This then means that you’ll soon, once again, have hot water and heating.

If, however, you find yourself on first name terms with your local Gas Safe heating engineer, and there’s more time without hot water than there is with it working, then now may be the time to consider a new boiler.

Even the best combi boilers and best system boilers have their off days.
