[QUOTE="Andy™, post: 388298, member: 2012"] diverters are usually set to CH then moves to DHW as required, so unlikely to be that. if it was stuck on DHW then turning heating on would shut down boiler on overheat very quickly when you switch the heating on, what exactly happens? any lights come on to say heating is on or any fault? you have switched the CH on correctly, havent you? usually needs both power selector set to CH & DHW, and any timers / thermostats switched on [/QUOTE]
