Washing it probally will not help much of anything, you most likely fried something on the logic board, why you would power something while its obviously shorted out is beyond me.

Honestly seeing the progression of this thread I would not suggest you mess with another machine, there are things inside that could very well kill you. Along with your rushed, half hazard, total density, its just a recipe for danger

Find a machine on ebay that is in good working condition and be happy
