Replacement parts for the DLC-7 & DFP-14 model food processors.

Yes it does. It is a snug fit on the blade shaft, if you mean the tall shaft that powers the shredder discs? The short one that holds the cutting blade is not removable.

The set screw on the blade assembly is loose. If the motor does not spin then that is a different story.

If the unit works OK with other attachments and the problem is only with the one cup; then the blade may be loose and spins on the shaft, the connection gear under the bottom is worn or binding up. Debris is stuck around the blade shaft or from heating up the metal parts expanded and bind when turning.

If the motor is running, the problem can be that the motor shaft is spinning inside the drive sleeve. Replace the sleeve. That is more common than a motor failure.

My old Cuisinart has this problem because the motor shaft and the corresponding socket on the cutter are worn. The shaft has jammed in the cutter. To un-jam it, stick a bar of wood behind one blade of the cutter (I use the wood handle of my dough whisk) and give it a light, sharp tap with a hammer. Check after every tap to see if it is loose, if not do it again. You want to tap against the back side of the cutter, not the cutting edge side. The socket on your cutter may be cracked, allowing it to open up and slip (and jam) under the stress of cutting. You'll probably need a new one. If the motor shaft is also worn, that can also be replaced. The new part is about $10. I got a few more months of life from my cutter by reinforcing the inner socket with a thin plastic tube from the barrel of a syringe.

it is either the seal around the blade shaft that is worn (but if it is worn so much that liquids can leak, then you probably heard the machine vibrate more than normal or sound screechy). Or it is the gasket at the bottom of the container that is not seated well or is out of shape. Goodluck, Macgivor

I phoned the 800 number at Cuisinart (800-243-8540) and the person who answered the phone explained to me what to do: Fill the bowl with the hottest tap water I have (but not boiling) above the entire blade (including the part that fits over the shaft). He said to pulse a few times, then try to pull it off, but not to expect it to work right away. He said to do this until it comes off and that it could take 1/2 hour. I did what he said, and the blade came off after the first pulses. But also, the water was pouring out all over the counter--leaking between the bowl and the base (possibly because my old work bowl is also cracked, but I'm not sure).

I was told that the problem would happen again, and that I needed replace the blade and the shaft (which is cracked, as he guessed), both of which are available from Cuisinart.

If the blade is actually fused, I would seek professional help to avoid slicing your fingers off. You can test to see if it is fused by removing the lid of work bowl, twisitng work bowl to the left, and removing the work bowl - if work bowl will not come off (difficult even under normal circumstances), then find out from Cuisinart if you are still under warranty.

Had the same problem. The Cuisinart folks said to fill it with hot tap water - not boiling - then turn it on and off. The heat from the water will unstick the bowl. If it doesn't work first time - refill with hot water and try again. Worked like a charm for me.
