Fan won't work on worcester 24i junior combi boiler?

My hot water was working perfectly yesterday and have not heard any unusual noises from the boiler, however went to run some hot water today and water just runs cold.

It appears that the fan is trying to start as it makes the usual start up noise ( well I think it is the fan noise) for a couple of seconds and then nothing. Also tried the heating and again the same problem. I have tried the reset button but to no avail.

The fuses on the PCB have been checked and seem fine

It is like it tries to start but then just goes dead if you know what I mean. Does anyone have any suggestions as to what it might be?
