My friend just passed me the same model for repair. I figured out how to unassemble.
First, remove the pan. It can be remove by pushing down, and twist counter clock wise.
Second, remove 8 screws at the bottom of the base, which are accessible after remove the pan.
Third, remove 2 screws at the side wall, which is above the 8 screws.
You will need short screw driver to remove the side screws.
Forth, remove the 8 screws at the top, which is what you have done
