Troubleshooting Steps for Navien Water Heater
When your Navien water heater won’t turn on, follow these steps to identify and resolve the issue effectively.
Checking the Power Source
- Inspect the circuit breaker for any tripped switches. If a breaker is tripped, reset it and see if power is restored.

- Confirm the power switch is turned on. Look for a dedicated switch near the heater or an external control panel.
Inspecting the Thermostat Settings

- Confirm the gas supply is active. Ensure the gas valve is open and check for any kinks in the gas line that could obstruct flow.
By following these troubleshooting steps, you can quickly identify the reason your Navien water heater isn’t turning on and take the necessary actions to restore its function.
