- Calibration Issues: Thermostats can become miscalibrated. If the heater fails to heat water even at the correct setting, recalibration might be necessary.
- Environmental Factors: Check if the surrounding temperature impacts the heater’s efficiency. If it’s too cold in the installation area, insulating pipes can prevent heat loss.
By checking electrical systems and thermostat settings, you can diagnose and resolve common heating issues with new AO Smith water heaters effectively.
Troubleshooting Steps
You can follow these troubleshooting steps to identify and resolve issues with your new AO Smith water heater not heating properly.
Checking Power Supply
- Inspect the Power Connection: Confirm that the water heater is plugged in securely. A loose connection can disrupt power flow.
- Examine the Circuit Breaker: Check the circuit breaker for your water heater. If it’s tripped, reset it and observe if the heater powers on.
- Test the Power Outlet: Use a multimeter to check if the outlet delivers the correct voltage (typically 240 volts for electric water heaters).
- Look for GFCI Reset Button: If your water heater has a Ground Fault Circuit Interrupter (GFCI) outlet, make sure to reset it.
- Access the Heating Element: Turn off the power and remove the access panels on the water heater to reach the heating elements.
- Visual Inspection: Look for any signs of burn marks or damage. If the elements appear corroded or broken, replacement is necessary.
