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
The manual says:
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.
I had an electrician here today so maybe something went wrong with the c/h system when the electrics were turned off.
