Hello,
I had the same problem. Yes, remove the factory silver label/sticker from the bottom (be gentle, it is still possible to slowly remove it without damaging it, so when you put it back it looks decent again). You’ll find a slot with a visible metal screw-head-like-shaped thing , so you can insert a screwdriver there and hold it firm while turning the blade counter clockwise on the other side of your grinder. Now, I wanted to remove some water that got under the grinding metal bowl last night, so I looked closer at the center of the rotating core and depressed black plastic latches using thin plastic material (I used a small rectangular piece of a clear plastic form salad/spinach container from my local grocery store-worked well and didn't scratch any surface). Then I was able to shake out the metal bowl and voila. I was actually surprised that there was another plastic bottom there, so there was a hope that the water did not get down to the electric motor. Yeah !!! I wiped the whole thing, dried it and assembled together. Remember, do not attempt to use running water to clean the grinding compartment after, e.g., grinding spices, herbs etc. Just wipe it with a clean dry or damp cloth. Anyway, the grinder still works, so no water damage or danger of electrocution.
I was wondering how to effectively remove the bottom part of the grinder, there is four sets of latches there, but I was not able to loosen them, even if inserting three screwdrivers there at the same time. Has anyone tried? I hate to scratch or damage those kind of things for esthetic reasons, so it would be good to know exactly how it is supposed to be removed. I hope this helps, good luck to all.
