Jobo CPA-2 fuse problem

[argos33]

I have a Jobo CPA that keeps blowing the fuse to the motor. No matter what fuse I put in it, it blows within minutes. I have looked over the circuits and don't see any places where it is shorting out. The pump and temperature features still work, just not the motor. It is a pretty big pain to take the thing apart each time to change the fuse so I have given up on it, but if anyone has any suggestions for fixing it I would be eternally grateful.

Would it be possible to post the schematic?

Greetings,
If you are using Expert Drums, this may apply. I don't know if it's still possible to get the upgrade though.

Good Luck!

I do not know the CPA, just wondering whether they have a similar EFI capacitor installed?

How many different fuses are in the CPA?

Thanks for the info. I will have to go check my CPA to see which one I have.

Thanks for the suggestions, I think there are two: one main (for pump, heater) another for the motor. I should add that when I first got it, it was working fine. Then on the second run it blew the fuse on the wash cycle. I replaced the fuse once or twice after that and each time it blew within 30 seconds to 2 minutes (with no tank).
