Locate the Power Button

Before resetting your Navien water heater, you need to locate the power button. The power button is typically located on the front panel or control panel of the unit. It may be labeled as “Power” or have the symbol of a power on/off switch. Take a careful look at the front of your water heater unit to find the power button.

Turn Off the Power

Before attempting to reset your Navien water heater, it’s important to ensure that the power is turned off. This is crucial for your safety and to avoid any electrical accidents.

Locate the main power switch or circuit breaker that controls the water heater and turn it to the “off” position. This will cut off the electricity supply to the water heater and prevent any potential harm.

Ensure that the power is fully turned off by double-checking the water heater and making sure everything is quiet and inactive. It is also recommended to unplug any electrical connections to the water heater if applicable.

Once the power is off, you can proceed with the next steps to reset your Navien water heater and address any issues you may be experiencing.

Find the Reset Button

To reset your Navien water heater, you will first need to locate the reset button. Depending on the model, the reset button may be located on the front panel or on the control box. Look for a small button marked “Reset” or with a symbol that resembles a circular arrow.

The reset button is typically used to restart the water heater and clear any error codes that may have been triggered. It is an important troubleshooting tool that can help resolve common issues and get your water heater functioning properly again.

Before pressing the reset button, make sure to turn off the power to the water heater. This can be done by switching off the circuit breaker that supplies electricity to the unit. Once the power is off, you can safely press the reset button to initiate the reset process.

If the reset button does not seem to be working or the issue persists after resetting the water heater, it may be necessary to call a professional technician for further assistance. They will be able to inspect the unit and provide a solution to any underlying problems.

Remember, always refer to the manufacturer’s manual for specific instructions on resetting your Navien water heater, as different models may have variations in the reset process. Following the correct procedure will ensure the safety and proper functioning of your water heater.

Press and Hold the Reset Button

If you need to reset your Navien water heater, the first step is to locate the reset button on the control panel. The exact location of the reset button may vary depending on the model of your water heater, so it’s important to consult the owner’s manual or look for any labels or markings on the control panel. Once you have found the reset button, follow these steps:

1. Switch off the power: Before pressing the reset button, it’s crucial to switch off the power supply to the water heater. This can be done by flipping the appropriate circuit breaker in your electrical panel or by unplugging the heater from the power outlet. This step ensures your safety while performing the reset.

2. Press and hold the reset button: Once the power is switched off, press and hold the reset button for at least five seconds. Some models may require a longer press time, so refer to the owner’s manual for specific instructions. Holding the button down will reset the control board and clear any error codes that may have been triggered.

3. Restore power: After holding the reset button, you can switch the power back on. If you had turned off the circuit breaker, flip it back to the “On” position. If you had unplugged the heater, plug it back into the power outlet. This will restore the power supply to the water heater, allowing it to function again.

Note: It’s essential to troubleshoot the cause of the initial error that led you to reset the water heater. Resetting the unit may resolve minor issues, but if the problem persists, it’s advisable to contact a professional technician to diagnose and fix the underlying problem.

Wait for the Water Heater to Reset

Once you have completed the reset process, you will need to wait for the Navien water heater to reset itself. This can take several minutes, so be patient and allow the system to complete its reset cycle.

During this time, the water heater may make some noises as it recalibrates and restarts. You may hear the water heater turning on and off or the sound of water flowing through the system. This is normal and should not cause any concern.

While waiting for the water heater to reset, it’s important to avoid any further attempts at resetting the system. Multiple reset attempts can disrupt the troubleshooting process and may even cause additional issues with the water heater.

Once the water heater has finished resetting, you can proceed with testing the hot water to ensure that the reset was successful. Turn on a faucet and wait for the hot water to flow. If the water heats up as expected, then the reset was successful. However, if the water remains cold or if you encounter any other issues, it may be necessary to contact a professional technician for further assistance.

Turn the Power Back On

Once you have completed the steps for resetting your Navien water heater, you can turn the power back on. Locate the electrical panel or breaker box in your home and find the breaker that corresponds to your water heater. Flip the breaker switch back to the “on” position.

After turning the power back on, wait a few minutes for the water heater to initialize. You should see the temperature display or other indicators light up. If the display shows any error codes or if you notice any unusual behavior, consult the owner’s manual or contact a professional for further assistance.

It’s important to note that resetting your water heater may only be a temporary solution. If you continue to experience issues or if the problems persist, it’s recommended to contact a qualified technician to diagnose and repair any underlying problems with your Navien water heater.
