How do i open the krups coffee/spice grinder bottom part?when i try to run it , the baldes don't trun i want to know what's the problem?

SOURCE: Coffee grinder

Mine had a piece of the top/bean lid broken off and lodged in the groove preventing the lid from going down far enough to release the safety switch which is on the right (as you look at the front) in the bottom of the groove. Note that there is another safety switch in the body of the grinder above where the ground coffee comes out that must be working as well.

I have the same issue. You need to take both dials off, then on the bottom, there are 4 tabs on the inside. Seperate the halves and you will see them. Towards the front and halfway back. Pry the halves apart enough to push the top towards the bottom and it slides apart pretty easy. The tricky part now is finding the replacement part. I have super glued my switch and I want to do something to try and repair it further. Maybe epoxy. I called Krups and they can't sell the part to me. I called one of their service centers and they can't sell the part to me. So, if someone knows where to get the part, I am all ears :)

I took the bottom off mine and found that a hose that connected to to the water level tube had become disconnected. 
In order to get the bottom off you need a Torx internal tamperproof pin (6 lobe) screwdriver to get the 5 screws out.

Had the same problem.  Took out every screw I could find, and pried open the stainless steel shell (not easy) and eventually disassembled it to the point where could get at the broken switch. Cut the wires to the switch and tied them together with some black electrical tape effectively bypassing the safety switch, then put it back together. Tools I used were a screwdriver and a pair of pliers. Thing has worked for 2 years since.  It will run without the lid on, so dont stick your fingers in. 
Overall took me about 45 minutes, but well worth it instead of adding to landfill and spending more money.

Remove the the four screws at the rear of the machine you will need a pair of pliers to do this and remove the hinged lids on both sides.looking down from the top and to the front you will see a phillips screw on either side,remove these and the top will come off you will then see the channels that the coffee runs from the machine now just use a piece of suitable material to clean the pipe,easy!
