Why doesn't it work is often used in the abbreviated form, but when not using this, you would use Why does it not work. Why does not it work is not grammatically correct.
Why does it not work?
Why does not it work?
As commented and answered earlier, the first example is right.
englishgrammar explains further; 'contracted and uncontracted negative questions have different word order'.
Doesn’t he understand? (Auxiliary verb + n’t + subject)
Does he not understand? (Auxiliary verb + subject + not)
