I have a ideal logic combi 24 boiler with a fault showing code f1, I know this is the pressure, I've turned valves but nothing have happened the pressure is still nearly 0, I've also checked to see if there have been any leaks from radiators but nothing can you help me?
you use the filling loop to pressurise the system to around 1.1bar.goes from the 15mm cold water feed to the 22mm CH return pipe.type filling loop in to youtube and watch some of the videos
