We have had a Kenmore electric hot water heater for about 8 yrs. I have replaced both thermostats, but not done anything with the coils. This afternoon my called to tell me that both kids ran out of their showers complaining of no not water (They're 5 and 7 so not taking the typical teenage showers yet,
It's a 50 gal heater, and we usually give them both baths, so I don't know that water volume should be an issue.
When I came home and checked the hot water this evening, It was fine. I was thinking that it needed thermostats again, but now that the water is hot again, I'm wondering.
Is there any realistic cause of temporary hot water shortage? single coil going bad?
I checked the breaker reset button on the upper thermostat and it did not click when I pressed it, nor I hear any obvious churning that usually accompanies coils jumping to life, though there is hot water in the tank.
