Hello, I have a problem with the Class 24FF boiler. After turning on the boiler, err108 appears to me. How to fix it. The pressure gauge is standing still. It is audible as if something was preparing for heating, but after a few seconds error 108 appears.
Before that, it was ok when I turned the boiler off and on without turning it OFF.
Please help.
Thank you.
