Gas supply issues

Common causes of Noritz error code 29 include:

Clogged Condensate Drain Line: One of the common reasons for error code 29 is a clogged condensate drain line. This blockage can prevent the proper drainage of acidic condensation, leading to issues with the neutralizer system.
Condensate Neutralizer Issues: Problems with the condensate neutralizer, such as a malfunctioning pump or a blockage in the neutralizer, can trigger error code 29 on your Noritz water heater.
Exhaust Blockages: Blockages in the exhaust venting system can also result in error code 29. These blockages can restrict airflow and cause the neutralizer system to malfunction.
Improper Installation: If the Noritz water heater was not installed correctly, it could contribute to error code 29. Issues like improper venting or drain line installation may lead to this error.

Venting problems

When dealing with Noritz error code 29, it’s essential to consider the common causes that can trigger this error. Understanding what might be causing the issue can help in troubleshooting and resolving it effectively.

One of the primary culprits behind error code 29 is a clogged condensate drain line. This blockage can disrupt the drainage of acidic condensation, impacting the neutralizer system’s functionality. Clearing the drain line is a crucial step in addressing this issue and ensuring proper water heater operation.

Issues with the condensate neutralizer, such as a malfunctioning pump or blockages in the neutralizer itself, can also lead to error code 29. Checking and potentially replacing components of the neutralizer system can help resolve this particular cause of the error.

Blockages in the exhaust venting system are another common trigger for error code 29. These blockages can impede the airflow, causing disruptions in the neutralizer system’s operation. Inspecting and clearing any obstructions in the exhaust venting can aid in fixing this issue.

Additionally, improper installation of the Noritz water heater can contribute to error code 29 occurrences. Issues like incorrect venting or drain line installation can lead to operational problems, resulting in error codes being displayed. Ensuring the water heater is correctly installed based on manufacturer guidelines is vital in preventing such errors.

Troubleshooting Steps

When dealing with Noritz error code 29, it can be frustrating trying to figure out what’s causing the issue. Here are some troubleshooting steps that can help you resolve this error:

Check the water flow: Make sure there are no obstructions in the water flow system that could be causing the error.
Inspect the water inlet filter: A clogged filter can restrict water flow and trigger error code 29.
Examine the condensate trap: Ensure that the trap is not blocked, as this can also lead to the error.
Verify the exhaust venting: Check for any blockages or issues in the venting system that could be causing improper venting.
Reset the unit: Sometimes, a simple reset of the unit can clear the error code. Turn off the unit, wait a few minutes, and then restart it.

By following these troubleshooting steps, you can effectively address Noritz error code 29 and get your system back up and running smoothly.

Check gas supply

When troubleshooting Noritz error code 29, it’s crucial to follow specific steps to identify and resolve the issue effectively. Here are some troubleshooting steps that can help in fixing error code 29:
