Circuit Breaker Trip Water Heater

[sajaca]

Replaced water heater almost 5 years ago. Recently the circuit breaker trips on average once or twice a week. Was thinking about attaching a hose and draining it due to sediment build-up. I understand there is a reset switch located somewhere on the heater that may affect this as well. I'm sure the answer is already here in the archives somewhere, however I didn't know where to look. Thanks..........

If you will read the posts under "Rheem hot water tank/with cold water" you will see a detailed description of how to check the problem.
