Put in nuts and turned to mush

Unless you've been trying to chop nuts and bolts, the sharpness of the bade isn't so very important, as the food processor also depends upon the highish speed with which the blade rotates.

If the blade is severely blunt you can try sharpening it with a kitchen steel.

that will be just fine.

When you are trying to chop things in the magic bullet make sure that you use short pulsing movements, don't just hold it down. This will make things go mushy instead.

This is the advice they give on their website:

You may be over processing your food by letting your Magic Bullet slip into Lock On Mode (see video demonstration of Lock On Mode) when you should be using the Pulse Technique (see video demonstration of the Pulsing Technique). Please read the Pulse Technique instructions on page 15 of the user manual or follow the steps shown in these video demonstrations and you'll be making perfect chopped onion, salsa and all your favorite textured foods in no time.

Hi,

Your PowerBlend Duet™ comes with a food processor button. This button is the perfect speed for all your food processing tasks. Always use this speed when using the food processor. You may also use the Pulse button with this function for pulse-chopping.
To use your food processor, make sure that the bowl is assembled properly and the blade or slicing/shredding disc and the cover are locked into place.
When you use the control panel, the LED will light next to each button you press.
Press the On button. For continuous operation, press the Food Processor button. Motor will start if you have followed assembly instructions.
To turn motor off, press the Food Processor button again or the Off button.
For on/off operation, called pulse-chopping or pulsing, press the On button, press the Pulse button, and then press and release the
Food Processor button the desired number of times. Motor runs as long as you hold the Food Processor button down. The motor stops when you release control switch. Try it a few times.
You control the duration and frequency of pulses by the length of time you hold the Food Processor button down and the rate at which you press it. Pulses should be short bursts. Allow enough time between pulses to let food in work bowl fall to bottom.
Always use the Food Processor button for pulse/chopping. Never turn cover back and forth to start and stop processor.

The DLC-7 SuperPro is awesome -- very powerfull. Be aware they are 1.5 horsepower; the blade can take your hand completely off in a blink of an eye. Because of the potential danger, SAFEGUARDS are in place such that everything must be aligned and in correct position or it WILL NOT POWER-UP. So, yes, is very likely the safety switch.

Simple test: Use just the BASE, (no work bucket, no top, no blades), such that if it starts, only the spindle will turn. There is a little black button on the base, just back of the spindle. Use a chop-stick to depress it. Plug-in, press the button w/chop-stik, press the PULSE button. It should power up.

Presuming it powered up okay, the "problem" is probably in how the unit is assembled; such that the button is depressed properly.
1. The work bowl must be all the way down on the base, and the alignment column in the back, work bowl base skirt turned to the "Hard Stop". It will feel very solid when docked properly.
2. The top inserts and rotates into and snaps into position while pressing the plunger into the button.

It all sounds too easy, but if something is just a little off, the plunger doesn't plunge ind the power doesn't go on.

These are FABULOUS machines -- spend the time into getting it working. The near- equivalent if something this robust and powerful in today's products will cost nearly a THOUSAND dollars - seriously.

I need the exact same part.

If you have a multi-speed processor, the speed setting is too high.
If there are oinly two speed settings, try using a slciing disc instead of the chopping blade. Use a pulse function if available. Cuisinart has hundreds of different food processors, so I am just speaking in generalities here.
