How to Fix Takagi Error Code 441

Tankless Water Heaters

In most cases, error codes aren’t the end of the world, but they are annoying. Even if an error code can be fixed easily, like Takagi error code 441, they’re never a welcome sight. 

After over 15 years of diagnosing and resolving tankless water heater error codes around Los Angeles and its surrounding cities, we’ve got a keen understanding of what makes these machines tick. With 13 of those 15 years in partnership with Takagi, we also have specialized knowledge of the brand’s tankless water heaters. 

In this article, we’ll fill you in on what Takagi error code 441 means and how you can resolve it. To be upfront about the fixing process, you will need professional assistance to get this job done right the first time if you don’t have the know-how. 

But before we dive in, let’s address some advice we’ve seen floating around the internet. Some articles claim that simply unplugging your tankless water heater and plugin it back in will resolve your error code. While this might clear the error code, the underlying issue will still persist, meaning the error code will be back. 

Now, let’s start with an overview of what Takagi error code 441 means. 


What Does Takagi Error Code 441 Mean?

If you run into Takagi error code 441, it means there is an issue with the flow sensor. While the flow sensor triggers the issue, it typically has more to do with the debris build-up in the pre-filter or elsewhere in the system. 

When this error code triggers, there is most likely a blockage or debris build-up in your plumbing system. This blockage prevents the adequate flow the tankless water heater requires to kick on. The issue could be as simple as a dirty aerator on your kitchen sink. 


So, How Do You Fix Takagi Error Code 441?

Because this error code can take some know-how to diagnose and resolve, we recommend calling a technician out to your home to resolve the code correctly the first time around. Once your technician arrives, they’ll inspect your Takagi tankless water heater and your plumbing system to track the source of the issue. 

After your technician locates the cause of Takagi error code 441, they’ll be able to get your Takagi tankless water heater up and running fairly quickly. Whether it's a dirty aerator, a blockage, something amiss with the water supply, or busted wiring, your technician will relay your options. 

Repair time will vary since the necessary action can be anything from simple maintenance and clearing away debris to replacing bad wiring if there’s damage. 

If your technician finds that the issue could have been prevented, they’ll likely advise you to keep up on annual maintenance. Performing annual maintenance helps sidestep issues like debris build-up and other types of issues caused by normal wear and tear. 


Running into Other Issues?

Takagi error code 441 is inconvenient since it can leave you and your family without hot water, but it’s far from the only error code that may pop up over the course of owning a Takagi tankless water heater. Even something as simple and straightforward as a maintenance code like error code 991 can lead to some serious issues if untreated. 

If you’re keen on not being out of the loop the next time your tankless water heater runs into an error code, then it’ll be helpful to brush up on the top five most common Takagi error codes in Los Angeles County and its surrounding area. 

Getting familiar with the common Takagi error codes can help you in specific circumstances. For instance, if you live in an area with hard water, like Los Angeles County, then being aware of error code 711 should be a priority since it signals the end of the road for your heat exchanger in most cases. Likewise, understanding that error code 991 is the first sign of something needing your attention can save you a massive headache in the future.
