probably due to the thermostatic control as I just found out from this forum.
I am a bit of a DIYer, & just needed a little advice on how to go about dismantling it.

could be your thermocoupler breaking down,need to be replaced. or as in my case i bled the radiators and because they are clogged up that blocked the pipes and shut the system down.now with no water going through i cannot restart it so now need to flush it all through
