My cuisinart burr coffee grinder will not turn on

This model sometime gets plugged up with grounds.

Unplug the grinder, and remove the bin where the grounds go. Look inside the grinder part where the grounds come from the grinder into the bin. This should be clear, and you should be able to see part of the grinder wheel inside. If this is plugged up with grounds, then you'll want to clean it out, but it's possible that the motor has already burned out (we killed two of them last year at my office this way)

Pour out any whole beans that are in the top part. You can pour them in a bowl to save them, you don't have to throw them away.

Unscrew the top part until it detaches from the grinder. This will take 20 or more rotations -- just keep turning it counter-clockwise.

You'll want to do this next part over a sink or a counter that's easy to clean -- you're going to dump a lot of ground coffee.

Looking into the grinder from the top, you'll see the grinding wheel in the center, and packed coffee grounds around the edges. Use a plastic knife or bamboo skewer to clean out the ground coffee. Don't use a screwdriver, metal silverware, or anything metal, as this can damage the grinder housing. You also want to clean from the bin opening. When you're done cleaning, the grinder wheel should turn freely.

Reattach the top portion, put the bin back in place, and turn the grinder on. It should turn on and spin the grinder wheel. If it still doesn't, then your motor is burned out. :(

If it does turn, then put the coffee beans back in and enjoy a cup -o- joe!
