I'm not getting any power to my upper thermostat, but checked the
breaker and have 120 and each pole there. I checked the top of the
heater, where the wires come out of the wall and attach to the wires
going into the heater, and I get 2.5 volts coming out of the wall.
Any thoughts on where/what happened?! Do I have to dig through my
walls?! FWIW, I'm in Tampa, FL area, home of massive lightning, which
we had yesterday, but only noticed no hot water today, after two
people showered okay. Possibly they had enough hot water even if it
went out yesterday? But still, I have power out of the breaker...?
Thanks.

Test the voltage across the two wires coming out of the breaker. Touch the wire,
not the breaker. If you see 250 or so volts there, and not at the other end of
the wires, replace the wires.
