I have a heatline combi boiler with no external model number. The bar pressure dropped to zero and shows no sign of rising. I have no hot water or central heating any longer - does anyone know how I can fix it?
There a switch underneath, its a black switch i think, u have to turn that round til the pressure goes to about 2

Pressure wont rise unless you fill it manually via a filling loop (braided hose with a black isolating tap, or flat head screw in the middle) top it up to around 1.2 bar and be sure to close the water off when you have reached said pressure. Reset boiler and bobs your uncle
