Hi! my friends vokera linea 24 boiler pressure has dropped i tried to fill it using the relevant tap which i have done many times before but this time the pressure gauge isn't rising and i can't here any water coming in, i tried to undo the filling loop to check it but hot water is coming out, by the way the heating is on, does this mean the inlet cock is faulty, any idea.
