Ideal Classic Sealed System not working

Ideal Classic boiler with the sealed system factory fitted above the boiler not working for heating. The boiler only heats the radiators as the hot water is an Economy 7 immersion heater system.

After switching on the heating at the timeclock,  there is some noise from the boiler, but it is not firing up. Through the gaps in the control box I can see there is an LED alight on the PCB, so the boiler is receiving the demand. I remove the sealed system cover, and can feel the pump vibrating. I remove the boiler case, and the fan is not spinning. Spinning the blades using my screwdriver gives it the jump-start to get it going again and the boiler fires up.

I remove the old fan and fit a new one, and everything is working as it should.
