Mixer will turn in an empty bowl, but stops once it meets any resistance.

Follow these steps to find out the problem else call Cuisinart { 1-800-726-0190 } for help :
•1
Remove the back cover by removing the small Phillips screw at the top of the back cover.
•2
Place a rag or cloth over the spring to keep it from moving.
•3
Plug in the mixer.
•4
Move the switch lever to "Stir." This may or may not start the motor.
•5
Turn the two adjusting screws counterclockwise evenly until the planetary turns approximately 60 times per minute.
•6
Test the planetary by holding a right hand finger lightly across the beater shaft. Count how many times the shaft touches the finger in 15 seconds.
•7
Turn the two adjusting screws until the shaft brushes the finger 15 times in 15 seconds.
•8
Lock the two lock nuts using an 11/32" wrench. Check the speed again.
•9
Make further adjustments, if necessary, without loosening the lock nuts on the control board. Unscrew the two adjusting screws.
•10
Move the planetary to speed 6. At this speed, the planetary should turn 180 times per minute. Check speed as you did for the first speed. The planetary will brush your finger 15 times in 5 seconds if the speed is correct.
•11
Turn the adjustment screw at the bottom of the control plate if the speed is less than 15 times in 5 seconds.
•12
Check the revolutions again. Keep adjusting the screw at the bottom until the correct speed is reached. You don't need to lock down this screw.
•13
Test all speeds from "Stir" to #10. If "Stir" and #6 speeds are properly adjusted, the other speeds should be correct automatically. If you notice a definite change in speed between #8 and #10, you have adjusted the mixer speeds correctly.
•14
Replace the back cover and screw in the back cover screw.

Cuisinart hand mixers are not repairable. You can buy replacement accessories like beaters, but you can't buy any internal replacement parts.

I have a Cuisinart HM-70 and I stripped the plastic gears inside by trying to mix a really thick dough. It was easy to open and get to the plastic gears. When I called Cuisinart to try to get replacement gears, they said that they don't sell replacement parts and their hand mixers are not repairable. I looked all over the internet and no one sells internal parts.

Unless your mixer is still under warranty, I believe that you're out of luck and your mixer is headed to the electronics recycle pile.

Most handmixers today are sold with plastic gears - including high end brands like Viking. For me the lesson learned is to buy low end hand mixers (don't buy a top of the line 9 speed mixer) and treat them like they're disposable when they break.

Here's what really happens. The hook has a shaft screwed into it with bayonet fittings that lock into the mixer. The shaft has a locknut where it screws into the hook. If the locknut becomes loose then the shaft can screw in too far making removing from the mixer almost impossible. Try to get a slim wrench onto the locknut and loosen it off enough to allow the hook to be unscrewed. After the hook comes off, move the locknut down the shaft until the whole assembly can be removed from the mixer. Re-attach the shaft to the hook making sure that the exposed portion of the shaft is long enough to allow for easy removal from the mixer. Tighten the locknut and you will never have the problem again.
