Hi, can anyone help with an F1 code on a logic combi 30 boiler? Ive tried turning the blue and black valves but nothing happens 9part from water coming out!) and the pressure is still at zero. Do I need to use a filling loop to attach between the two? teh boilers a few months old but there doesnt seem to be a loop with it?
any help is greatly appreciated.
