I have a water heater (installed in 1995) in the house I bought 2 years ago. About 9 months ago, it stopped working. I looked and it tripped the circuit breaker for the water heater. I turned the breaker back on and reset the water heater (open panel + push reset button). It worked fine for 6 months. About 3 months ago it stopped working, but this time did not trip the breaker. I reset it, and it has been working fine since.
I suppose it is nearing the end of its' life, but wanted to see if anyone has had a similar experience or has any input as to what could cause it to stop working twice (trip breaker once), but work again after being reset.
