Incorrect installation can lead to water leaks or electrical hazards. However, for informational purposes, here's a general guideline on how to replace heating elements in an A.O. Smith ECL 30 200 water heater:

Warning: Electricity and hot water can be dangerous. Ensure the power and water supply are off, and take necessary precautions before attempting any work on the water heater.

1. Safety Precautions: Safety should be your top priority. Turn off the power supply to the water heater by switching off the circuit breaker or disconnecting it from the power source. Also, shut off the water supply to the heater to prevent any potential water leaks.
2. Drain the Tank: To avoid scalding and make it easier to work on the water heater, drain the tank. Attach a hose to the drain valve located at the bottom of the tank and open the valve. Direct the other end of the hose to a suitable drainage location or floor drain. Wait for the tank to empty completely.
3. Identify the Heating Elements: The A.O. Smith ECL 30 200 typically has two heating elements—one located near the top of the tank and another near the bottom. Identify the element you want to replace.
4. Access the Elements: Remove the access panels or covers that provide access to the heating elements. Use the appropriate tools, such as a screwdriver or wrench. Be sure to wear safety gear, including gloves and safety goggles.
5. Disconnect Wiring: Carefully take a picture or make a note of how the wires are connected to the heating element. The heating element usually has two wires attached—one for power and one for temperature control. Disconnect these wires from the heating element. Ensure the wires are labeled if needed for proper reconnection.
6. Remove the Old Heating Element: Use a suitable wrench or socket set to unscrew the old heating element from its mounting location inside the tank. Be cautious not to damage the tank's lining or other components during removal.
Install the New Heating Element: Thread the new heating element into the same location where the old one was removed. Ensure it's properly aligned and securely tightened. Do not overtighten, as it can damage the threads.
7. Reconnect Wiring: Reattach the wires to the new heating element following the notes or pictures taken in step 5. Double-check that each wire is correctly connected and tightened. Verify there are no loose connections.
Replace the Access Panels: Carefully reattach the access panels or covers, making sure all parts are securely in place.
8. Fill the Tank: Close the drain valve at the bottom of the tank and turn on the water supply. Allow the tank to fill completely. Check for any leaks around the heating element.
9. Power Restoration: Turn the power supply back on at the circuit breaker or reconnect the water heater to the power source.
10. Test: Test the water heater to ensure it is functioning correctly. Monitor the temperature of the water and verify that the heating element is heating the water as expected.
11. Monitor and Adjust: Keep an eye on your water heater for a period after replacement to ensure it is maintaining the desired water temperature and functioning properly.

If you encounter any problems during the installation process or have any doubts about your ability to safely replace the heating element, it's strongly recommended to seek assistance from a qualified technician or professional. Incorrect installation may lead to water leaks, electrical hazards, or damage to your water heater. Always prioritize safety when dealing with water heaters and electricity.
