• Main causes of the E110 error code include blockages in the air inflow pipes and a clogged or blocked exhaust pipe.
• To troubleshoot the E110 error code, start by checking and cleaning the air intake pipe and air intake filter.
• If the issue persists, inspect and clean the exhaust pipe.
• If troubleshooting doesn’t resolve the E110 error code, seek professional help from a licensed technician or contact Navien technical support.

Potential Causes of Navien Error Code E110

In order to understand and troubleshoot the Navien E110 error code, it’s crucial to identify the potential causes that lead to this issue. The E110 error code primarily occurs due to abnormal air pressure within the system. This abnormal air pressure can be caused by various factors, including:

• Blockages in the air inflow pipes
• Blockages in the air intake filter
• Clogged or blocked exhaust pipe

These issues disrupt the proper airflow and combustion, triggering the E110 error code. To resolve this error code, it’s essential to thoroughly inspect and address these potential causes. Let’s take a closer look at each of these factors:

Blockages in the Air Inflow Pipes

Blockages in the air inflow pipes restrict the flow of air into the Navien tankless water heater. This can be caused by debris, dirt, or any other foreign objects that inadvertently enter the pipes. It is important to check and ensure that the air inflow pipes are clean and free from any obstructions. If blockages are found, they should be cleared to restore proper airflow and eliminate the E110 error code.

Blockages in the Air Intake Filter

The air intake filter plays a crucial role in preventing contaminants and debris from entering the Navien tankless water heater. Over time, the filter can accumulate dirt and become clogged, hindering the airflow. Regularly cleaning and maintaining the air intake filter is essential to prevent blockages and ensure optimal performance. If the filter is dirty or obstructed, it should be cleaned or replaced according to the manufacturer’s instructions.

Clogged or Blocked Exhaust Pipe

A clogged or blocked exhaust pipe can also contribute to abnormal air pressure and trigger the E110 error code. Obstructions in the exhaust pipe can prevent the proper release of combustion gases, causing backpressure within the system. Inspecting the exhaust pipe regularly and clearing any blockages is necessary to restore the correct airflow and resolve the E110 error code.

By addressing these potential causes, you can effectively troubleshoot and resolve the Navien E110 error code. If you have completed these steps and the error code still persists, it is recommended to contact a licensed technician or Navien technical support for further assistance.

How to Troubleshoot and Fix Navien Error Code E110

If you encounter the Navien E110 error code, there are several steps you can take to troubleshoot and fix the issue.

First, check for any blockages in the air intake pipe. Inspect the outer end of the pipe for any obstructions, such as snow in colder areas.

If there are no blockages outside, proceed to clean the air intake filter. Turn off the heater, remove the front panel, and unscrew the mesh filter for cleaning.

Clean the filter using a brush to remove any dirt or debris. If necessary, you can also clean it under tap water. Just make sure to dry the filter completely before reinstalling it.

If you’re short on time or unable to clean the air intake pipe and filter immediately, you can temporarily reset the heater to clear the error code. However, it’s important to clean the air intake pipe and filter as soon as possible for a permanent solution.

If the E110 error code persists even after cleaning the air intake and exhaust pipes, we recommend contacting a licensed technician or Navien technical support for further assistance. They will be able to provide detailed troubleshooting guidance and instructions on resolving the issue.
