Your electrics may look in good order to the naked eye, but if it's tripping the circut board then there is definately a short circut, either in the machine itself or in the wall socket
I would seriously consider having an electrician look at this problem because if you don't you could wake up one night with your house on fire.
Your circut board is sending you a warning that something is very wrong, so HEED THE MESSAGE.
Don't ignore electrical faults.
