There’s no current on the EGC.
I believe your water heater's metal pipe connections are acting like a parallel path or the only path for return current rather than the neutral or EGC. This can be a location that has a neutral or ground connection on any of the copper pipes in the house, coming through to the water heater. Can you confirm that there is zero current on the cold water or hot water lines connected to the water heater?
