Hi, I know nothing about boilers and am hoping someone can help. I think we had a leak on one of our radiators, and I think I've sorted that but in the meantime, the central heating system has lost pressure and the boiler is now flashing at 0.1 bar...no heat, and I have no idea how to restore the pressure. I wonder if anyone can help,
Thanks

there will be a small blue tap on the underside of the boiler, turn it to top the pressure up, then turn it fully off again. if it doesn't work then get an engineer out, as the built in filling valves on these boiler are notoriously bad for blocking up and it will most likely need replacing.
