Badger 5 hums, allen wrench doesn't fix

[KarenGarner]

My brand new (3 week old) Badger 5 has been working beautifully until yesterday. It tripped the breaker and now hums but doesn't work. The allen wrench turns freely in both directions at the bottom. I put my hand inside (I know I'm not supposed to) and the blades turn freely in both directions. I pressed the reset button. Do I need to replace my new unit? I don't have the sales slip any more so I don't know if the warranty will apply. Boo hoo, it's only 3 weeks old......
Is there anything else I can try...?

Shut off the power to the unit. Take off the wiring plate underneath and check to see if the wires came loose from the wirenut and is touching the case. It also could be a faulty unit. Perhaps one of the windings is touching the case. These things make a lot of vibration and you could have gotten a fluke.
