How do you increase the water pressure on Vaillant Ecotec plus boiler?

I have the above combi boiler, I am not too sure about the model no. it is about 2 years old. The pressure is .4bar and I cannot figure out how to increase this, there are about 5 pipes below the bolier and I have tried opening the valve on what appears to be the water pipe, but I cannot hear any water going into the boiler. Thanks in advance

thanks very much, this has helped me also. I see lots of us have had the same issue, it should come in the instructions booklet. thanks again.

Thanks - worked for me too, BUT.....

Cold water comes out of the right hand valve when I turn it. About 100ml in 5 seconds.

Anybody know if I should I be concerned?

under the boiler you'll see two grey coloured valves that should say closed on them as they face you, turn both of these valves to open position, you should hear water going into system, fill to about 1 bar. make sure to turn both valves back to closed position afterwards.
