Hi,
I have the above timer attached to a Concord combi boiler. at 4.30 pm this afternoon the timer appears to have stopped working and no longer rotates. I have checked the fuse on the plug for the timer and indeed changed it, to no avail. I currently therefore have no heating or hot water as the programmer / timer cannot switch the heating or water to on, even with the manual (ON) setting
Can anyone suggest anything i should check?
Many thanks ina dvance,
Max
