I have a combi boiler which until today was working fine, however this morning I turned off the electric to fit a couple of new plugs and when I turned the power back on the boiler heats the water no problem but the central heating does not work, the orange light it not on and the motor does not fire up. Any suggestions please.

Have you checked the room thermostat and programmer are calling for heat ?

have you re-programmed the timer with having the electrics off ?

When the heating is turned on, are you getting electricity to the boiler ? can you check this ?

what orange light ? the central heating demand light ? flame LED ? power LED ?
