Valliant Boiler Error Code F22
The Vaillant F22 error code = low water pressure. Also displayed as F.22, the water pressure in the boiler needs to be increased again to work. Your Vaillant boiler will only work when the water pressure is around the 1.5 mark on the gauge.
You could attempt to fix this yourself provided you know what you’re doing, but if you wanted to take the hassle out of it, a Gas Safe Engineer would be able to do this quickly.
To increase the boiler pressure, first switch the boiler off and let it cool down. Next, find the filling loop (most likely to be under the boiler, and is a metal hose with a valve at each end). Turn the valves to allow water to enter the boiler, and keep an eye on the pressure gauge as you do so. Turn the valves back to their starting point once the pressure gauge displays 1.5.
Boilers gradually lose pressure over time, if you notice a sudden drop in pressure there could be a leak and it is important to flag this with a Gas Safe engineer. You should not attempt to repair this by yourself. Click here to contact us to help.
