Mend Ferroli Optimax Boiler Heating Fault

Ferroli Optimax not heating water?

I had the hot tap on today and the water suddenly went cold. Now when you turn the hot tap on the boiler is not firing up. There is no fault code showing on the boiler and the central heating appears to be working fine - it;s as if the boiler doesn't realise I'm drawing water?
