Pushing the red button or resetting the cirucuit breaker should give you hot water again, but it will probably be excessively hot also. DO NOT change anything until you test the thermostats and the elements. You probably have a shorted out lower element, but any combination of bad thermostats(2) and/or elements(2) can give your symptoms. If you start changing things without testing them, you can spend a lot of money needlessly.
