Mend Vaillant ecoTEC plus 831 Combi Boiler Pressure Heating Hot Water

Combi boiler - no pressure - no heating or hot water?

I have a Vaillant ecoTEC plus 831 - my radiator was not working and I stupidly bled it dry - my boiler now has no pressure so has turned itself off. I need to refill it and have read the instructions but when turning the two 'keys' on the filling loop until they are loose the water doesn't flow. No idea what I'm doing wrong. So worried cos of the snow and it freezing the pipes and have a young baby worried as her room is sooo cold.

yep that's the one, turns out the threads are gone on the 'keys' covering the screws and because am renting don't want to tamper, lovely man from agency came out and has sorted it, just need new fixings - key things! Thanks for your response!

There is usally a flexible loop pipe with a plastic turn tap, is this where your trying to fill it from.
