"F02 = Motor jammed or tacho detached".

Check the motor hasn't jammed up somehow, or that the small tacho coil (the thing that detects the speed of the motor) on the end of the motor hasn't dropped off (tip the machine back and it's in between the brushes - it should be held in place with a clip. If it's hanging loose it's the fault)

This fault code basically means the PCB cannot detect any impulses from the tacho coil on the motor, so the main implication is that the motor is just not running. However, because other fault codes cover most of the other motor faults, the PCB thinks the motor may be physically jammed. That is, as far as the PCB is concerned, it is supplying the motor with power, but it can't detect the motor is running.
