Vaillant ecoTEC pro 28 combination boiler - anyone know how I refill the boiler? Problem occured today after electrician did some work and had to turn the power off.
The bar pressure guage shows F22
Manual says the boiler needs filling with water
Having read pages and pages of info. I cannot understand how to fill the system
4.3.2 Checking the system pressure
• Check the water pressure of the system using the
pressure gauge (1) before putting the boiler into operation.
For the heating system to operate properly, the
indicator on the pressure gauge must be in the dark
grey zone when the system is cold. This is a filling
pressure between 1.0 and 2.0 bar. If the indicator is in
the light grey area (below 0.8 bar), fill the system up
with water before putting the boiler into operation.
