Ideal Logic F2 fault code

Ideal Logic F2 fault code explained

If you have an Ideal Logic boiler you may see the F2 fault code at some point.

This fault code will cause your Ideal Logic boiler to stop working, leaving you without central heating or hot water.

The F2 fault code on an Ideal Logic, essentially means that the printed circuit board on the boiler detected a flame and the burner was lit, but it not longer detects a flame.

If you look in the Ideal Logic installation manual under the F2 fault code it states the following;

“FLAME LOSS”

Ideal Logic boilers like most modern boilers, have failsafes built into them to ensure that the boiler works safely.

One of the failsafes in place is flame detection, which is done via a process called flame rectification.

The printed circuit board on an Ideal Logic boiler knows if the flame has gone out after it was initially lit and detected.

If this happens the boiler will attempt to relight the burner three times and if unsuccessful the boiler will shut down and display an F2 fault code.

Like some fault codes on an Ideal Logic boiler, the F2 fault code does not actually tell you exactly what is wrong with the boiler.

Unfortunately there are quite a few different possible cause of the F2 fault code. Possible causes include some of the following possibilities;

Faulty gas valve, faulty printed circuit board(PCB), faulty flame detection lead, blocked condensate trap, blocked or frozen condensate pipework or flame detection electrodes.

So as you can see there are many different components on a boiler that can cause the F2 fault code on an Ideal Logic boiler.

This is why it is important to get a suitable Gas Safe registered heating engineer with experience on Ideal Logic boilers, otherwise you could waste money fitting expensive parts to your boiler that are unnecessary.

Gas valves failure on the Ideal Logic range is not uncommon.

If your gas valve is failing, your boiler may work intermittently after a reset and display other faults codes at times such as the L2 fault code.

When to call a gas engineer to fix your boiler

If you are experiencing the F2 fault code on your Ideal boiler, it is important to take action as soon as possible. While some issues can be resolved by homeowners themselves, others require the expertise of a qualified Gas Safe registered heating engineer.

Because the F2 fault code can be caused by several different faulty parts, it is extremely important to get a suitable heating engineer with experience on Ideal Logic boilers.

Otherwise you could end up wasting money fitting parts to your boiler that are unnecessary.

Often you will be able to reset your boiler and get it working again if it’s showing an F2 fault code .

However in general this is just a short term solution and usually your boiler will probably stop working altogether at some point, leaving you without hot water and heating.

So it usually best to get a qualified heating engineer to have a look at your boiler at your earliest convenience.

How to prevent the F2 fault code

A lot of the time certain faults on a Ideal Logic boiler can be prevented with regular annual servicing and maintenance.

This is sometimes true of the F2 fault code as well.

However most of the parts on an Ideal Logic boiler that can cause the F2 fault code are non serviceable components.

This includes the gas valve. There is nothing that can be done on a service to make the gas valve last any longer.

What an engineer can do to they help prevent the F2 fault code include;

ensuring that the condensate trap and pipework are clean and have no blockages, ensuring that the ionisation probe(flame detection probe) and heat exchanger are clean, the air/gas intake venturi and gas injector is clean, and that the boiler combustion parameters are correct by check them with a flue gas analyser.

Ideal Logic boilers affected by the F2 fault code

The F3 fault code on Ideal Logic boilers can affect any combination boiler, any system boiler or any heat-only boiler.

Below is a list of Ideal Logic boilers that can be affected by the F3 fault code;

• Ideal Logic Combi C24, C30 and C35 combination boilers
• Ideal Logic + Combi C24, C30 and C35 combination boilers
• Ideal Logic Combi 2 C24, C30 and C35 combination boilers
• Ideal Logic Max Combi C24IE, C30IE and C35IE combination boilers
• Ideal Logic Combi ESP1 26, 33 and 38 combination boilers
• Ideal Logic System 15, 18, 24 and 30 system boilers
• Ideal Logic Heat 12, 15, 18, 24 and 30 heat-only boilers

Frequently asked questions:

Is my boiler showing an F2 fault code worth repairing ?

Yes definitely, most of the time your broken Ideal Logic boiler displaying an F2 fault code will be worth repairing.

Obviously the cost to repair your boiler will be determined by which parts need to be replaced.

You would need a competent, Gas Safe registered heating engineer to have a look at your boiler and make an assessment to determine exactly which parts might need to be replaced.

Before replacing your boiler it is always worth getting a suitable Gas Safe registered heating engineer, with experience working on Ideal Logic boilers, to make an assessment of your boiler so you can determine whether it is worth fixing not.

Can I repair the F2 fault code myself?

Sometimes you can solve an F2 fault code yourself. You can ensure there is no issue with your gas supply by checking other gas appliances.

If your boiler has a condensate pipe that runs externally you could check to make sure it hasn’t frozen.

Aside from that repairing the F2 fault code will usually require removing the cover of your Ideal boiler to replace parts which you are not legally allowed to do unless you are a Gas Safe registered heating engineer.

Is the F2 fault code dangerous?

No definitely not , the F2 fault code is not inherently dangerous, it’s the opposite.

Modern Ideal Logic boilers are designed with fail safes in place to make sure that the boiler will only work if it safe to do so.

In general if you have an F2 fault code you may be able to reset your boiler for a period of time but then it will probably stop working altogether.

As such if your boiler is coming up with an F2 fault code, the best thing to do it get it repaired at your earliest convenience, by a suitable Gas Safe registered heating engineer – ideally one that has experience working on Ideal Logic boilers.
