strange really as it should not have stopped you getting hot water but you will have to refill the boiler to do this there should be a pipe or filling loop somewhere that connects the cold water feed to the boiler there will be one or two taps on it depending on who fitted it, open the taps untill the pressure reads 1 to 1.5 bar or come to the marker on the pressure display then turn off the taps and it should work now if i can be of any further help please ask
