Electricty works in strange ways, but can't answer that question.

There might be more damage to the pump than just a nick on the wire. I am guessing the epoxy seal(normally green covering the entire inside of the pump might be starting to crack too, might just be a hairline crack if it is not obvious but just enough for water to seep in.
