    My boiler keeps firing up when all heating and water is timed off.
    The Boiler shows a status "C" and the burner light flashes, fires up for a few minutes, stops, fires up again, and so on.....
    Looking online it may be a motorised valve problem, is this the case, and how much am I looking at to get it replaced.?

    The terminal in the wiring center that fires the boiler, is the one with the orange wire. If that's live, when hw and ch are off it's either the program or the 3 port,

    Bit of fault finding will give the answer
