Anyone know how to change dispenser servo? Wont fill

Ive got a barely used form 2, awful machine. First one broke on first print. Now this one broke on about the 5th print of its life. (bought new). The tank wont fill (no its not the rubber cap). I just dont have a schematic to see what all needs to be taken apart.

Should probably just throw it in the garbage and find a superior chinese unit. As a formlabs customer, I can tell anyone…dont make the mistake of becoming one. Worst investment ever.
