The Vaillant Boiler F22 Error Explained
The Vaillant boiler F22 error is an automatic response from your boiler when it recognizes low water pressure and protects internal components. The fault status is typically shown alongside an error code on your boiler screen.
What Causes the F22 Error?
- Insufficient Water Pressure
Boiler Pressure: You’ll Find the Pressure Gauge on Your Boiler Your boiler works best when it is within a certain pressure range—commonly around 1.5 bar. Leaking can create gas pressure drops, or the water can naturally evaporate over time.
- Faulty Pressure Sensors
This means that if your internal pressure sensor is faulty and alters what your boiler believes to be its pressure level, the error code might still occur.
- Leaks in the Heating System
Old or damaged pipes can cause leaks, which can wear your system’s water pressure down over time.
Why Should You Deal with This Quickly?
Allegedly neglecting the F22 howling, the F22 error can cause more severe boiler harm and significant repair costs and suffering. Tackling the fundamental issues will allow you to keep the boiler in working order by applying regular work to your framework and keeping it running well.
How to Avoid the Vaillant Boiler F22 Error
1. Check Boiler Pressure on a Regular Basis
Monitor the pressure gauge on your boiler. When the boiler is off, the reading ideally should lay between 1 and 1.5 bar.
- If it’s too low, check your boiler manual for guidance on how to re-pressurize the system.
- Do not overfill; its very high pressure causes other fault codes.
2. Check for Leaks
Check your heating system (and visible pipes) for signs of leaking water.
- Leaks often leave telltale signs: damp spots, rust, or puddles under pipes.
- If there is a leak, call a Gas Safe registered engineer to have it repaired as quickly as possible, before it gets worse.
3. Bleed Your Radiators
Air that’s trapped inside your radiators can lead to uneven heating and drops in the boiler pressure. How to bleed a radiator safely—follow these steps:
- Turn off your heating system.
- Open the bleed valve with a radiator key.
- Let the air out until the water starts dripping and close the valve.
4. Annual Boiler Servicing
Routine maintenance performed by a qualified professional is key to avoiding pressure-related issues. A Gas Safe engineer will:
- Check pressure levels.
- Find and resolve small problems that may turn serious.
- Keep the important elements clean and optimized.

5. Add a Pressure Relief Valve
A pressure relief valve can help stabilize water pressure, which can avoid a sudden pressure drop, and in turn, this prevents the F22 error from occurring. If your system doesn’t come with one, ask your engineer about adding one.
6. Know When to Get a Hand from a Pro
While certain problems can be addressed at home, such as a dusty air filter, more complicated malfunctions, like faulty sensors or recurring pressure drops, usually need a professional’s touch. These issues should be diagnosed and remedied quickly, so for peace of mind, hire a Gas Safe registered engineer.
