Mend Grant Combi 90 V3 Boiler Heating Pressure

Grant Combi 90 V3?

I am stuggling with airlocks in my system and no matter how much I bleed the radiators I cannot seem to have heat in all the radiators. Someone suggested that there might not be enough pressure in the boiler, how can I check that or increase the pressure?
