Troubleshooting Steps
Navigating issues with your Navien water heater can be straightforward when you follow these troubleshooting steps.
Checking the Thermostat Settings
Ensure the thermostat settings align with your hot water needs. Adjust settings to a temperature between 120°F and 140°F for optimal performance. If the settings are below this range, temperatures might not reach user comfort levels. Check for any error codes on the display that could indicate configuration issues. Refer to the user manual for specific guidance on adjusting settings.
Inspecting the Power Supply
Confirm that the power supply is functioning correctly. Check circuit breakers to ensure power isn’t interrupted. You might also need to inspect any electrical connections for damage or looseness. If the unit isn’t receiving adequate power, it can struggle to heat water. Plugging it into a different outlet can help rule out outlet issues.
Flushing the System
Flush the system regularly to remove sediment buildup that can inhibit heating efficiency. Begin this process by turning off the water supply and power to the unit. Attach a hose to the drain valve and direct it to a suitable drainage area. Open the drain valve to let water flow out, flushing away any debris. Once the water runs clear, close the valve, turn the water and power back on, and check for improved heating performance.
