The timer of our combi boiler is not working. It doesn't turn around. ?

The timer of our combi boiler is not working.I've adjusted the timer to the correct time but it seems that the timer won't turn around. I ended up over riding the timer. Switch it on when we need it and switch it off when we don't need it.

Model: Fanned Flue Combinaqtion Boliler GC no. 47 047 20. Glow-worm.

Please help.
