Listed below are the common Firebird fault codes as described by the boiler manufacturer along with a possible cause.
Firebird Boiler Error Codes
Occasionally some things can go wrong, that’s why we’ve created our handy at-a-glance table of Firebird
1. Central heating not coming on
If your central heating isn’t coming on then it’s worth checking that your thermostats are turned on,
whether the bottom of the radiators are warm (may need to be bled) and low boiler pressure. If
none of these seem to be causing the issue then it’s likely to be an appliance issue, which will need a
Gas Safe registered engineer.
2. Low boiler pressure
If your central heating system isn’t working correctly then your boiler might be low on pressure.
You can easily check the pressure of the boiler by looking at the built-in pressure gauge –
if you see anything below 1 bar then the unit is low on pressure.
Fix low boiler pressure
Increasing low boiler pressure is something that’s safe to do yourself, our guide to low boiler pressure
can take you through the steps. Don’t hesitate to contact a Gas Safe registered engineer if you feel
the slightest bit unsure.
3. Boiler leaking
A leak can begin for one of many reasons, but it normally means that an internal component has broken,
usually a seal or valve. In time, this may lead to corrosion, rust or cause electrical components within
the boiler to short circuit.
Fix a leaking boiler
Once you spot the leak, turn the mains water supply off to prevent the leak from worsening.
You should contact a Gas Safe registered engineer as soon as you spot a leak from your central heating
system, even if it’s small.
4. Hearing strange noises
Limescale or sludge building up on your boiler’s heat exchanger can cause the boiler to make some
strange noises which is known as kettling. This build-up can restrict the flow of water within the
heat exchanger causing the water to boil then steam and whistle, like a kettle.
Fix strange noises
To allow the water to circulate properly, a Gas Safe registered engineer will be able to perform
a powerflush of the heating system, which involves flushing chemicals through the system to clear
any blockages. Once this has been done, it could be worth having a magnetic filter fitted to
the heating system which will catch any debris before it has chance to build-up.
5. Radiators not heating up
A number of things can prevent your radiators from heating up, but the most common reason
is sludge or air build-up in the system. If the bottom of your radiator is getting hot but not the top,
you may need to bleed it.
Fix cold radiators
Bleeding the radiators clears trapped air from the system, allowing the hot water to circulate around the entire
radiator. Our guide to bleeding radiators will take you through the steps if you wish to do this yourself but
otherwise, you should hire a Gas Safe registered engineer.
