Mend Vaillant Boiler Water Heating Problem Pressure

Valliant boiler - Hot water but no heating?

I'm guessing that the problem is that the pressure is too low, as it's under 1.0. I have followed the instructions to refill the system (opening the valve clockwise), but the pressure does not increase. What could I be doing wrong?
