    I've been having problems with my boiler since I moved house.
    Today my Hive thermostat was offline, then it recovered but after that my boiler's central heating had problems starting. I've reset the boiler AND turned it off/ on and despite that I am getting the above error - which I cannot even interpret to search Google for the error code.

    Hot water still works and so does the heating (but it does not go above 60 degrees on the display), and I can feel it's not working as it should. What should I do?

    It's not an error code, it's the syphon fill function.

    Ah I see - I was worried there for a second but that explains it.

    Thanks! Seems to be working now.
