Have Vaillant VCW GB 242 EH combi boiler.
Problems started immediately after turning water off at mains to fit new taps on bath.
Mains back on and radiators kick in fine but hot water only works if hot water tap is FULLY on. Can turn bath hot tap slightly down once it is hot but too much and it stops producing hot water. Other hot taps in flat only work if 2 taps are on.
Have searched the forum for answers but i've checked pressure and used to be just under 1 bar but have pushed this to 1.5 bars now but no real difference.
Looked at pump and cannot move the big screw any direction so i cannot bleed the pump.
Any ideas???it is doing my head in.
