What Does Navien Error Code 012 Mean?
If you see Navien error code 012 pop up, it means your tankless water heater is experiencing flame loss. This issue can have several different causes, with some being more common than others.
The first potential issue is gas pressure. If your tankless water heater has inadequate gas pressure, then it won’t be able to produce a flame, resulting in flame loss. This issue is one of the more common causes of error code 012.
There are several other issues that can trigger Navien error code 012. Another potential root cause is an internal leak, which is slightly more problematic. Other issues include an undersized gas line, a bad regulator, or in rare instances, a bad gas valve within the tankless water heater.
Now that you know how Navien error code 012 is triggered, let’s look at how you can resolve the issue with the help of a professional.
So, How Do You Fix Navien Error Code 012?
Once you’ve gotten in touch with a professional technician, they’ll come out and conduct a full inspection of your tankless water heater and full plumbing system. Quality companies perform full plumbing inspections to ensure that there is nothing else in the system causing the error code to pop. This inspection can also root out other issues that may need attention in the future.
Once your technician has found the cause of the error code, they will address it accordingly. These fixes could be anything from resizing the gas line and bringing the gas pressure up to spec to calling the gas company out to replace a bad regulator within the tankless water heater.
Seeing Other Error Codes?
It’s probable that you’ll end up experiencing other types of error codes over the course of your Navien tankless water heater’s lifespan. Not every error code is easy to resolve, and some may result in complete replacements if the damage is severe enough.
