Tripping breakers? Sounds like something has gone seriously kaput. That is the extent of my German diagnosis. Or, rather, diagnosis in German.
First things: is this appliance actually rated for the 220 volts common to the Continent? If it's a 110 volt model then I could see a problem with running it as twice the rated voltage.
Second: has it been disassembled to see if there is a simple crossed wire or short circuit?
Third: are the motor windings fried?
Fourth: Is the motor bearing seized up?
Fifth: Is there a sausage maker attachment for said Sunbeam?
Good luck!
