My Vokera gas bolier has stopped working today, the water pressure gauge is only 0.4, the bolier is located in the kitchen, How can I increase the water pressure, I have 2 red valves and 1 orange valve in the hot press,just wondering which one is for topping up the pressure for the gas boiler and do I just turn the valve one twist
the bolier makes noise but no flame is coming on so no heat
cheers
