So a couple of articles ago, we wrote about The 7 Most Common Noritz Tankless Error Codes. Today we will be taking a deep dive into the second Error Code on that list, Noritz Error Code 12. This error code is very similar to Error Code 11 in the sense that it can be caused by a lack of gas or airflow.
What Is A Noritz Error Code 12?
A Nortz Error Code 12 means that the tankless unit has a weak flame and that water is not being heated properly. The Error Code will show on your screen if the unit is detecting flame or if the flame is being extinguished during operation.
- Insufficient gas supply
- Insufficient air supply
- Debris on the flame sensor
- Airflow: Make sure there are no blockages preventing combustion
- Flame rod/sensor: Clean any debris. Remove any obstructions in the system
- Replace the flame rod: If it can’t be cleaned or is faulty
- Adjust the airflow or gas valve: This will help create a sufficient flame
