Step 1 · Turn Off Power and Water
The absolute most critical step is to ensure your safety by completely isolating the water heater from its power source. Go to your home's main electrical panel (breaker box) and locate the circuit breaker that controls the electric water heater. It is often a double-pole breaker (two switches linked together). Flip it to the 'OFF' position. Next, locate the cold water inlet pipe on your water heater and turn the shut-off valve clockwise until it stops. This will prevent more water from entering the tank. To be absolutely certain the power is off, remove the element's access panel and use a non-contact voltage tester to verify there is no electrical current at the element's terminals.
