Troubleshooting Steps for AO Smith Water Heater Not Turning On
If your AO Smith water heater isn’t turning on, follow these troubleshooting steps to identify and fix the issue.
Verify Power Supply
- Check the Power Source: Ensure the water heater is plugged in and the outlet is functional. Testing with another device can confirm if electricity is flowing.
- Examine Breakers and Fuses: Inspect the circuit breaker for tripped breakers or blown fuses. Reset any tripped breakers or replace blown fuses as needed.
- Look for GFCI Outlets: Identify if your unit connects to a GFCI outlet. Reset it if necessary, as these outlets can trip due to overload or moisture.
Check the Thermostat Settings
- Assess the Temperature Setting: Confirm the thermostat setting is appropriate. For most residential water heaters, the ideal temperature is around 120°F to 140°F.
- Change to a Higher Setting: If the thermostat setting is lower than usual, adjust it upward and observe if the heater activates.
- Test for Functionality: If the heater doesn’t respond after adjusting, the thermostat may be faulty and require replacement.
- Locate the Reset Button: Find the reset button, usually on the upper thermostat for electric models. It may also be near the burner access for gas models.
- Press the Reset Button: Press it firmly to reset the heater. This action can restore power to the unit if it’s tripped due to overheating.
- Monitor the Heater: After resetting, watch for signs of operation. If it doesn’t turn on, further inspection might be necessary, indicating a possible deeper issue.
Common Causes of Non-Functionality
Understanding why your AO Smith water heater isn’t turning on helps you troubleshoot the issue effectively. Here are some common causes to consider:
Faulty Heating Element
A faulty heating element may prevent your electric water heater from generating hot water. Check for signs of burns or breakages on the heating element. If you notice damage, replace it with a compatible model. Use a multimeter to test for continuity. If it shows no continuity, replacing the heating element is necessary.
Issues with the Gas Supply
For gas models, gas supply problems can hinder operation. First, ensure the gas valve is open. Inspect the gas line for leaks or blockages. If the pilot light won’t ignite, examine the thermocouple, which might need cleaning or replacement. A qualified technician should handle persistent gas issues for safety and compliance.
Sediment Build-Up
Sediment build-up in the tank can affect the water heater’s performance. Regular maintenance helps prevent this. To address sediment accumulation, flush the tank periodically. Shut off power or gas, drain the tank, and refill it until the water runs clear. Scheduling this maintenance annually contributes to longevity and efficiency.
When to Call a Professional
Recognizing when to call a professional can save time, money, and further complications with your AO Smith water heater. If troubleshooting steps haven’t resolved the issue, consider seeking expert help.
Signs You Need Expert Help

- Unusual Noises: Loud banging or popping sounds often indicate sediment build-up or a failing heating element.
- Water Leaks: Any sign of leakage around the heater requires immediate attention to prevent water damage.
- Discoloration or Odors: Cloudy or smelly water can signal serious problems within the tank that need a professional’s assessment.
- Error Codes: Electric models may display error codes. If you can’t understand the codes, consult a technician.
- Expert Diagnosis: Professionals can pinpoint issues that may be difficult to identify on your own.
- Quality Repairs: Technicians provide repairs using proper techniques and tools, ensuring safety and efficiency.

Maintenance Tips for AO Smith Water Heaters
Regular maintenance keeps your AO Smith water heater operating smoothly and efficiently. These tips help prevent common issues and extend the unit’s lifespan.
Regular Inspection and Cleaning
Inspect your water heater every few months. Look for signs of leaks, rust, or corrosion around the tank. Check the connections and valves for wear. Cleaning the outside of the unit ensures dust and debris don’t obstruct airflow.
Flush the tank at least once a year. Sediment can accumulate at the bottom and affect heating performance. To flush, turn off the power or gas supply, connect a garden hose to the drain valve, and allow the water to flow until it runs clear.
Additionally, check the anode rod every two to three years. The rod prevents rust build-up inside the tank. If it’s heavily corroded, replace it to maintain the tank’s integrity.
Recommendations for Longevity
Maintain the temperature setting on your thermostat at 120°F. This temperature balances comfort and energy savings.
Use quality water softeners if your area has hard water. They help reduce mineral deposits, keeping your tank and heating elements in better condition.
For gas-powered heaters, ensure the venting system is clear. Blocked vents can cause improper combustion, leading to safety hazards. Regularly inspect and clean the vents as needed.
Consider professional maintenance every few years. A technician can perform an in-depth inspection and service that you may not manage alone. Regular maintenance helps maintain efficiency and prevent costly repairs down the road.
