F22 boiler fault code - what does it mean?

Have you spotted an F22 fault code on your boiler? Don't fret, our boiler engineers can help you understand what it means, explain what might be causing it, and even offer a repair if required. Read on to find out more.

We at Go Assist appreciate that when something goes wrong with our boilers and error codes appear it can become extremely confusing to understand what's actually wrong with your boiler.

F22 Fault codes are one of the most common faults our customers call us regarding. So below we have had our experts explain what this could mean. 

What is an F22 fault code?

If your boiler is displaying an F22 fault code, typically, this means that the water pressure in your boiler is low. This is a common problem and whilst it is inconvenient – in most cases, it can easily be repaired by our qualified engineers.

Boilers will constantly be monitoring the water pressure within the system if it does – the fault code will present itself. For a boiler to properly work it will need to maintain a balance of water and air to ensure it can provide hot water when required. The water pressure will need to be increased for the system to run again.
Pressure loss can be caused by various things such as leaks in your heating system, faulty component, or it can gradually occur over time.

Leaking – If you are suspecting that your boiler may be leaking – which is why your error code is showing – make sure to turn off the water supply to prevent damage or corrosion from occurring to any other elements in the boiler.

Fault components – If you don’t suspect that a leak has occurred within the boiler – it’s possible that you could be dealing with a faulty pump, broken pump lead or broken pressure sensor.
These elements being damaged or faulty would stop the water from being at the pressure it should be – therefore causing your fault code 22 to be displayed.

However, don’t be alarmed until you get an engineer out to you – sometimes this fault can be fixed quickly and easily – as boilers will lose some pressure over time. Although if you are experiencing sudden drops in pressure – it is a sign there’s a bigger issue and to prevent further damage from water or corrosion we would advise getting an engineer out as quickly as possible.

We hope that this overview of boiler F22 faults has given a brief understanding of what may be wrong with your boiler. Boilers have complicated systems, and we wouldn’t advise attempting to repair an issue yourself – especially when your household hot water depends on it.
