How to fill Vaillant Combi boiler?

Hi there

The pressure on my wall mounted Vaillant combi boiler (VCW sine 18 T 3 W F H) is low... I understand the boiler needs "filling". Does anyone know how I should do this - or do I need to call an engineer?
Many thanks

You should have a small tap on the filling loop under your boiler, turn it slowly and look at your bar clock, take it upto 1 bar, turn it off. Turn on your heating system wait until it is fully heated and check it's at 1 bar if not repeat.
