Take it back, it is under warranty right, you said it was taken out of the box.

Gears inside are probably broken, I have 3 of them to do this (i use them commercially) and decided to open one up to see and the gears were broken and stripped. So far I have not been apple l able to find any replacement parts.

Make sure the plug is securely plugged into the wall.
Next, remove and reattach any mixing arms etc that may be attached to the mixer. Having one not attached properly can result in a start, start.
If problem persistes make sure the speed is reset.

If problem continues, here is an excerpt from the user manual found here.

Problem: Your stand mixer has an
overload protection device and if
overloaded, it will shut down to protect
the motor.
Solution: In the unlikely even that this
happens:
• Turn off and unplug the unit.
• Reduce the load by removing some of
the ingredients, and allow the mixer to
stand for a few minutes.
Plug in and reset the speed. If the
stand mixer does not start when you
press the on button, allow the unit to
stand for additional time.

If you are still having trouble, the product comes with a 3 year limited warranty, so if you're bought it within the last 3 years it may be covered.

Good Luck!

I just got my dough hook unstuck! The problem was the bolt at the top of the dough hook. This bolt is used to adjust the height of the dough hook. This bolt came loose while mixing and went up towards the mixer. The force of the spinning actually tightened this bolt against the mixer so when I tried to release the dough hook by lifting and turning, it wouldn't lift. The bolt was in the way! The solution is to loosen this bolt. You'll need a thin wrench that's about 15 mm. You can test loosening this bolt on the other attachments since they loosen in the same manner. You'll have to bend the white shield down slightly to get the wrench in there. It's a tight squeeze even with a thin wrench. Hold on to the lower end of the dough hook and turn the wrench counterclockwise when looking down at it. Once you loosen the bolt, you'll be able to turn the lower portion of the dough hook to lower it. Then you can lower the bolt further. Once you have them low enough, you can remove the dough hook like normal - lift and turn. Sure beats boxing it up, shipping it for repair and paying for shipping both ways!
