Hi I appear to have a fault developing on this 10yr old boiler when the heating has gone off on the timer and the system is still warm the hot water side sometimes starts up on its own or fails to shut down when hot tap turned off. Has anyone had experience of this is it maybe a stock fault. If we are out and this happens then eventually the whole system shuts down I assume some sort of safety system takes over. Any ideas will be gratefully recieved.
