If it was working and recently stopped working, the heating element that heats the water probably went bad, no longer functioning. Check to make sure that there is or is not a reset button, and if there is, press and reset the heater. It's not difficult to remove the old heater element and replace it, but make sure the circuit breaker power to the water heater is off when you remove it. Take it to a water heating supply store, or large hardware store with the Brand and model number of your water heater (Reliance RELIANCE ELECTRIC WATER HEATER,model 606 ) to buy another one.

I wrote a page for changing water heater thermostat.
The photos take you through step-by-step
I recommend replacing both upper and lower thermostats so it eliminates thermostats as possible cause if water heater keeps overheating.

The Reliance 606 manual shows your water heater uses generic upper and lower thermostats from hardware store.

Likely the thermostat will solve the problem:
