Up until yesterday my system was working ok, with the hot water starting every day. I tesed the CH on Wednesday and that also worked fine. Yesterday mornig I put the CH on and in doing so blew a switch in the main fues box. After flicking back the switch the power to control panel did not return. Apart from the reset button underneath the unit is their any other switch I need to reset.

Top left corner of circuit board usually burns out , unplug your boiler clean up the burn and try to reconnect the loose wire with solder (i just twisted a piece of copper wire into the hole and twisted the wire to it coz i dont have a solder iron, its crude but it works !)
