Default Randall 4033 timer

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
