Problem with Greenstar condensing boiler

For a few weeks the heating has been on when the controls are set to hot water only.  Now today everything has stopped working, no heating or hot water.  Could this be the motorized valve that has gone?  I just need an idea of what it is before I call out a heating engineer.  Thanks in advance.

    It could be lots of things, from the information you have given it could be absolutely anything. 

    Why do you need an idea of what it is before you call out an engineer? Their job is to diagnose and fix problems.

    More info required, please.
    Is your boiler a combi or a regular/system one? Do you have a hot water tank?
