20 Most Recent Cuisinart SM-55 Stand Mixer Questions & Answers

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.

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!

The shaft of the beater is bent. After frustrating discussions with Cuisinart customer service, I was able to free my beater. First, you will notice that the beater screws onto the shaft. Unscrew it. Then, take the nut off the shaft. Next, put a wrench on the shaft that is only slightly larger than the shaft, followed by a washer. Next, screw the nut back onto the shaft. Finally, holding the wrench at the end, hit the wrench close to the shaft with a hammer. If the shaft doesn't come out, hit harder. Since the shaft is bent, you'll need to purchase a new beater.

You may want to look at the following components on the circuit board and replace them as necessary. If there appears to be no power to the machine (clock), the machine may have received a power spike from an unclean/fluctuating power source. Look at resistor R5. If it shows any signs of heat damage, replace it. Then look at diode D3, which has been the cause of malfunction on my unit for four times already. Replace this diode (10V, 1.3W) and it should run again. This diode is working like an over-voltage protection fuse (which should have been built into this machine with easy access in the first place!) and since it gets fried so often on my unit I'm planning an illustrated writeup on how to mod the board to make exchanging this diode easier and without disassembling the machine.
