What does F-22 mean on a Vaillant boiler?
A F22 error code is a common problem, and means that the water pressure on your boiler has fallen, and that it needs to be increased before the system will run again.
What is F 28 on a Vaillant boiler?
Vaillant officially defines the F28 error code as an ignition fault. There are many potential causes to this problem including an insufficient supply of gas, a faulty electrode or ignition lead. Therefore, the causes of the F28 fault can be broadly categorised into either an ignition fault or a gas valve fault.
Why is my boiler saying F 28?
The code means there has been a “lockout” in your boiler system. The boiler will attempt to light three times; if it cannot detect a flame, the F28 code appears, meaning there is a problem.
What should the water pressure be on the Vaillant Ecotec pro boiler?
A boiler’s pressure gauge will usually sit between 1 and 2 bars when it is turned on. The exact recommended pressure level will vary depending on the boiler manufacturer, but generally, anywhere between 1.0 and 2.0 bar is ideal.
How do I fix Vaillant F28 error?
The best way to resolve the F28 error code is to seek the help of a registered Gas Safe Engineer, who will be able to diagnose and repair whatever is causing the f28 code to be displayed. Use this clickable form to get a fixed price on the screen instantly.
How do I fix the water pressure on my Vaillant boiler?
Repressurising the boiler
- Turn off the boiler.
- Inspect the boiler filling loop.
- Turn the isolation valve anti-clockwise until the line on the valve is directly in line with the pipe.
- Turn the handle valve anti-clockwise.
- Watch the pressure gauge as you do this.
What should the pressure be on a Vaillant ecoTec Pro 28?
between 1.0 and 2.0 bar
The exact recommended pressure level will vary depending on the boiler manufacturer, but generally, anywhere between 1.0 and 2.0 bar is ideal. The boiler pressure level will rise when heating a home or providing hot water. However, it should still stay below the upper-pressure limit of 3 bar.

What does F22 mean on a Vaillant boiler?
The F22 error code on Vaillant boilers is an issue to do with low water pressure. It will usually be caused by insufficient water in your heating system and this will more often than not stem from a leak. Leaks will cause the drop in boiler pressure and this will, in turn, trigger an F22 error code when the pressure drops too low.
Are Vaillant boilers any good?
Vaillant boilers are pretty reliable but even they go wrong from time to time. More often than not it is the same faults that we see cropping up again and again and the F22 error code is perhaps the most common, especially on their EcoTEC models. The good news is that, in general, this isn’t an expensive or complicated issue to fix.
What should the pressure be on a Vaillant boiler?
You will want to set the pressure in your Vaillant boiler at around 1.5 bar usually, but always check your boiler manual to make sure this is correct for your model. Once you have topped up the pressure in your Vaillant boiler, you will then need to reset it. This is usually done using the reset button.
