I rather stupidly drained my electric water heater without shutting the power off.
When I refilled it, it did not heat, which is expected. I assumed I blew the top heating element as it drained, which would have then shut off the bottom heating element or perhaps both would blow.
However, when I took out a multimeter to test, the top heating element seems OK (set to 2kΩ registers .01), whereas the bottom seems shot (registered 1.5).
I am worried I am misunderstanding something though, as I don't see how draining a water tank can cause the bottom heating element to fail, while leaving the top one intact. It seems like either both need to blow, or just the top.
Do I have my interpretation of the multimeter reading backward? Any insight would be very much appreciated.
