The boiler should read between 1 to 1.5 bar of pressure when the central heating is cold. If this drops too low, below 0.5 bar for example, this normally means water has been lost from the central heating heating system and the filling loop must be used to replace this water.

Vaillant Boilers Problems Pressure have a three-pass round coil structure. A conical coil is used for the effective protection of the furnace wall at the boiler end. This product is equipped with an advanced combustion device and is fully automated in operation.

Water pressure sensor and/or pump defective, air in heating installation, too low pressure in boiler; connect external expansion vessel to return So basically the boiler is not detecting the pressure it is supposed to detect when the pump is up and running – which generally means there is fault with either the pump or the pressure sensor.

Low water pressure (F22 error) Vaillant boilers constantly monitor the water pressure and should it drop below a certain point, the F22 error code will appear on the digital display. All boilers will gradually lose pressure over time but if there’s been a sudden drop, it’s a sign that there’s an issue with the unit that needs to be fixed.

The Vaillant F22 error code (also Vaillant F.22 error) means that the boiler is low on water pressure and needs to be increased to work again. A Vaillant boiler will only work when it has the required water pressure, which should be around the 1.5 mark on the built-in pressure gauge.

Low boiler pressure is typically a result of a water leak or recent radiator bleed. These reasons are simple enough, but now you can go through a process of elimination to find out specifically why it’s happened.
