Hi Jack

It is a pressure system fault. You need to do following things on cold boiler: find a braided hose under the boiler, it will have two black or grey knobs. Turn both of them the way they are facing the same way. Look at the pressure needle and fill the system to the value of almost 1.5 bar. Then put the knobs back into its previous position. Restart the boiler.
