Besides, again. The healing machine isn't some normal piece of hardware either. As for the manual being within reach. Remember we just escaped from a really bad fire. Chances are it would have burned.

 as for the wires... You yanked it out from the wall so those need replaced. I highly doubt it has its own power supply. Reference the episode when Team Rocket cut the power to a Pokemon center and they needed Pikachu's electric to get it remotely back on. The machine itself was also down.

 that said even after repairing the wires... Still need a power source.
