How can I fix my ferroli optimax he 31?
I'm in a rented property with prepaid gas meter. My gas supply ran out and I found a error code A01 in my Ferroli Optimax HE 31 boiler. I topped up the gas and restarted the boilear and it came up with F40 fault code. According to the manual F40 means "high water pressure", so I released some water off my radiator until the pressure indicator points at around 1 bar and restarted my boiler. However, my boiler still shows the same fault code F40. Anyone had this experience before? Any idea what to check next?
