"Electrocution" was the wrong word (if you are still alive).
What probably happened is that some damage happened to some part while
moving it around. The damage could be in the form of insulation on a
wire getting worn off and that wire being a live wire contacting metal
parts that are in contact with the water. Or the damage could be in
the plumbing, allowing water to leak to where it can come in contact
with live electrical terminals somewhere.
To have been shocked, you would have been part of the return path of the
electrical circuit, which can typically be through ground itself, such as
a wet concrete surface, or any wet surface where the water contacts any
This is one of the reasons a ground fault circuit interruption device is
a requirement for hot tubs. Was one being used when you were shocked?
It is possible that somehow the return path you formed with the water
made it back to the neutral wire instead of the ground wire. In such
a case, a GFCI device would not detect anything wrong, and not trip to
open the circuit. But this is rare; most cases a fault path will be
with ground somewhere, either the grounding wire (connected to equipment
frames), or the earth ground itself (such as through wet concrete).
A seriously miswired electrical outlet or connection could also cause
this without there being any damage to the hot tub. If a live wire was
attached to the tub's ground wire, you could have this situation.
At this point, you should consider both the hot tub _and_
or connection or circuit it was connected to as unsafe until both are
inspected by a competent electrician who has experience with hot tubs,
and a cause is found and repaired, and the entire system tested over
a long term.
The manufacturer could easily blame you for damage, since if the cause
of the problem is in the tub, it most likely was damaged during moving.
