Help - Bolier Packed Up

[Nevin]

Help. I am up late doing DIY so I can sell my flat asap. I have just reconnected a radiator and tired to refill it with water. However on doing so my combi boiler appears to have stopped pushing hot water through. Its a Vaillant and is showing 0bar.

On my old one when this happened you simply turned a vavle to put water back into the system. However, this one doesn't appear to have any sort of valve. Any thoughts? Will it sort itself out in a bit?

Have now worked out where the valve is to top up the system (well hidden and unlabelled) and we appear to have heating again, which is nice.
