Question: Does this work bowl have the plastic plunger and spring in the back?
Document: The lid pops up in the back when fully assembled because there is not enough plastic ledge to offer enough leverage against the safety catch. If I hold the lid down then it works fine but I thought it would work like my old bowl did. Some other reviews mentioned older models with this problem but mine is pretty new and has the same problem.
I bought my 14Cup food processor in August 2012. I needed another work bowl and blade. The blade works great but the old lid does not push the safety catch down in the back unless you hold the lid down. My old bowl has about an inch of plastic "ledge" at the top edge to the right of the safety latch to help keep the lid down against the pressure of the safety catch.
A very small modification was required to get the old style top to engage the safety interlock mechanism. There is a narrow groove above the plunger where the lid rotates into to depress the plunger which activates a switch on the motor base allowing the motor to be turned on. The old style top needs a wider groove to activate the plunger when rotated into position. By simply cutting away a small plastic tab and making the groove wider, the old style top can be rotated into position and activate the plunger.
The problem is that the bowl does not fit smoothly nor does it depress the safety pin on the back. You could file the plastic but what's the point of that. It should fit.
I ordered this replacement part and it saved me from having to discard the entire appliance. The replacement works. I found that the plastic parts in the original machine are quite difficult to engage/disengage, and that is why I broke a piece off in the first place.I still find that the adjustment of the fine plastic parts (that piece at the back) that need to be in exactly the right position before the machine works to be rather trying.
The bowl I ordered and the lid I have do not fit. It looks the same as my old one and is the correct replacement number but I cannot make it lock . I had already washed it before I realized that it was not going to work so I didn't send it back.
Yup. A few years ago, my work bowl cracked so I ordered a new one from some vendor (not Amazon). It came, but it absolutely did not fit. Too tight. I sent it back in disgust and continued to use the cracked bowl, worrying that my family would get some horrible disease from the food stuck in the crack.So recently I figured I would try it again. This time I went to Amazon and read the product reviews.
Had my cuisinart food processor for 20 years and use it every week. The work bowl plastic cracked and I feel so fortunate to have found this available. Works great. Prompt delivery. Thanks
I have a 35-year old food processor that works great but the work bowl was cracked in several places. I was worried about finding a replacement because some of the reviews I read said I would have to 'shave down' a plastic connection. I decided to take a chance. I'm very happy with my purchase. It fits and works perfect. Thank you!
Had to buy a replacement bowl since our original broke. Figured it would be better to spend 35 bucks for a bowl than buy anew cuisinart even though 35 dollars is ridiculous for a piece of plastic. Be that as it may, I bought it and then it did not fit correctly with my machine. Had to use a knife to slice some plastic off so the machine could work properly. Not too nice for an expensive piece.
