Water heater made a pop sound when I plugged in without refilling water
I was in a hurry to get hot water going after taking the hot water heater out of the utility room when I put in new tile. I drained the water heater to remove and once done tiling, moved the water heater back into place, hooked up and plugged in before I had refilled it with water. The water heater is electric. As soon as I plugged it in, I heard a pop sound. I checked the breaker and it had jumped. I reset the breaker, filled the water heater and plugged back in.
2.5 hours later and I do not have hot water. What was the pop sound I heard when I plugged it in? Was this the sound of me ruining the elements which can be replaced affordably or did I do something worse?
