I'm not saying that your problem is definetly related to a wrong fuse, BUT just to rule that out as a first step....
In what way was it different to the original fuse?
Is F 10 L 250V what is marked on the FUSE or inside the device near the fuseholder?
What exactly is marked inside the device near the fuseholder? Picture possibly.
If F 10 L 250V is marked on the fuse, then it's a
FastBlow 10A 250V fuse. If the device POSSIBLY requires a slowblow 10A fuse,
and i'm NOT saying that it does, then the fast blow fuse may blow where the slowblow type does not. It all depends on the circuit current draw and how fast it rises AND what the manufacturer specifies as required: Fast Blow or SlowBlow /timed fuse.
If you find you need a fuse you can't easily find try FUSECO a Victorian company that can help with all sorts of fuses.....

NOTE:
Another possible cause of failure given the fuse blowing at turn-on
*, is a faulty bridge rectifier (shorted diode/s). Defective capacitors can also cause such failure modes. In either case, those would be an electrician or electronic tech / manufacturer analysis/repair job
*EDIT... Actually according to your initial comment it's not blowing at turn on but when the solenoid is about to engage so possibly not as I suggested above, but without the circuit diagram it's hard to know.
