Siemens mk50850 my siemens has a problem which happend due to over load i think the belt inside is slipped so i tried to open the base but i could't do that i have removed all the screw and i don't think any more screw there under the bush...i think the main shaft where we fix the bowl which is holding the whole thing could you help me to open the base pleasethank you sajith .

no belt, they are gear or direct drive.

I've not seen a bowl stuck on one of those unless the chopping blade is jammed on the shaft and preventing the bowl lifting up. Or is the chef bowl a smaller bowl that fits inside the main bowl?

These are called Torx security bolts. You should be able to find the right size at your hardware store.

Yes its easy to take the Magic Bullet apart.

1. First pry out the 4 black rubber feet on the base with small screwdriver and unscrew the 4 cross head screws revealed below.

2. Remove this black base to reveal the inner black base Unscrew the cable clamp - 2 screws and the 3 screws that retain the remaining black base to the body of the bullet - slide it off over the power cable.

3. Turn the bullet the proper way up and pry out the 3 white rubber bumpers with a screw driver blade that are set inside for the cup to rest on - each is located with two rubber pins. Once all 3 are removed you will reveal 3 more cross head screws - these countersunk - remove all 3 and then the internal motor will be free to lift out through the top of the Bullet casing.

4. Its possible to slip out the 3 white plastic sliders - taking care to note how they seat each on a small spring to cleanup both the slides and the sliders.

To re assemble step by step in reverse - noting to align the motor cable with the cutouts on the bullet base.

Sorry this website doesn't have parts nor any way to help ID or locate them for you

if its like mine the belt or pulley wear out mine took 8 years for it wear out. i couldnt find the parts so i took of the base(make sure its unplugged) remove the belt(hold one side of belt over the large cog and turn the cog, the belt should fall off) get a large rubber band (the width of the pulley)and twist the band over the pulley a number of times until it fits tightly over the pulley, replace belt and base and it should work.
this will work if the belt or pulley teeth are worn
my wife still cant beleive it worked

belt broken possibly.
not easy to change

THANK YOU!

The workbowl has a spring-loaded assembly inside. You can see it through the plastic. When the workbowl cover is in place and locked, it depresses the button on the base. If this is not happening, then you need to determine whether the workbowl or the cover is at fault. Once you figure that out, you need to replace the faulty one. I usually get my replacement parts at GourmetDepot.com.

You can get a completely new work bowl set (not the original parts) from Cuisinart for around $118.00. You could also buy one from a shady eBay seller and see if the oldie works. I am a collector of these myself, but in reality, it is probably cheaper to get a new Cuisinart food processor - they are nearly as good as the old ones.
