Tankless water heaters have quickly become a go-to option for many homeowners in Ball who want a more efficient and convenient way to get hot water. These systems heat water on demand, which saves space and energy compared to traditional tank models. While they usually run without problems, like any appliance, they can show signs of trouble. If your tankless unit flashes error codes, it’s signaling that something’s not working as it should.
Understanding what these error codes mean and knowing how to respond can save time, stress, and even help avoid long periods without hot water. Most codes are warnings that let you know the system needs attention. Some may be simple to resolve, but others can point to deeper issues that require our technicians to take a look. The key is to know what the code is telling you and what steps to take next.
Understanding Common Tankless Water Heater Error Codes
Tankless water heaters are smart systems, and one of their built-in safety features is the ability to display error codes when something isn’t working properly. These codes show up on the control panel or display and are meant to help homeowners and our technicians figure out the issue faster. While the codes can vary slightly by brand, many heaters use similar codes for common problems.
Here are a few error codes homeowners in Ball often come across with tankless water heaters:
– Error Code 11: Ignition Failure
This code usually means the heater is trying to start but can’t fire up. It could be caused by a gas supply issue, dirty igniter, or poor ventilation.
– Error Code 12: Flame Loss
If the flame goes out after ignition, the system will trigger this code. It may be due to weak gas pressure or blocked venting.
– Error Code 16: Over Temperature Warning
When the water gets too hot, this code kicks in. It’s a safety shut-off to prevent overheating. Causes include lime scale buildup or a failing temperature sensor.
– Error Code 59: Heat Exchanger Overheat
This error points to the heat exchanger running hotter than expected, often caused by restricted airflow or excessive scale inside the unit.
– Error Code 61: Fan Motor Failure
If the fan motor that helps control airflow fails, this code appears. It can be connected to wiring problems, a defective fan, or internal resistance.
Every one of these codes is a signal that something needs to be addressed. Ignoring them can shorten the lifespan of the system or leave you with no hot water when you need it most. We’ve had a homeowner in Ball ignore an Error 12 for several days, thinking it would resolve on its own. It didn’t, leading to a full system shutdown during a cold weekend and the need for emergency service.
Some error codes require only a quick check or reset, but others are signs that a part needs to be replaced or cleaned. Knowing the difference can save headaches and help prevent more significant issues later. If any of these codes show up and you’re unsure what to do, it’s best to let our technicians handle the inspection to avoid safety risks or causing more damage.
Troubleshooting Error Codes On Tankless Water Heaters
Running into an error code on a tankless water heater in Ball doesn’t immediately mean there’s a serious problem. Some issues can be addressed with a simple reset, while others signal the need for mechanical repair. Knowing how to respond when a code appears is the first line of defense against permanent damage or total system failure.
Start with the basics:
1. Check if the unit has power and the circuit breaker hasn’t tripped.
2. Reset the heater by powering it off for a few minutes, then turning it back on.
3. Inspect the gas supply line (if applicable) for any clear obstructions or shutoff issues.
4. Look at external filters or vents for dust, debris, or blockages.
5. If the display keeps showing the same error code after a reset, avoid trying to take the unit apart.
These steps work only for surface-level problems. Repeated error codes, especially those related to overheating or fan failure, usually point to internal issues. At this point, it’s time to have our technicians inspect the unit. We’ve had homeowners in Ball attempt multiple resets over several days, hoping the problem would clear out, only to end up with a non-functional heater and higher repair costs.
One of the most overlooked points during troubleshooting is safety. Water heaters deal with both gas and electrical systems, so poking around inside them without training or the right tools can lead to serious risks. If you’re unsure, it’s always safer to wait and let qualified professionals take over.
Why Regular Service Prevents Future Trouble
Many common tankless water heater problems trace back to lack of maintenance. Without routine care, mineral buildup can clog the heat exchanger, sensors can misread temperatures, and fans may strain under dust-covered vents. Even if the unit looks fine from the outside, parts can wear down inside long before you notice the symptoms.
Preventive service in Ball is the best way to avoid repeated error codes and unexpected system shutdowns. Our technicians can catch early signs of wear before they turn into performance failures. They’re trained to spot signs most people won’t see, like corrosion behind panels or damage to internal wiring. Regular service includes flushing out scale, checking sensors, and cleaning filters—simple tasks that help extend the life of the system.
When minor warning signs are left unchecked, they usually trigger the same error codes that confuse and frustrate homeowners later. Spending a little more time on upkeep now saves you from calling for urgent repairs when the unit suddenly stops working on a busy day.
Long-Term Tips To Keep Systems Running In Ball
Seasonal changes and local water conditions both affect how well your tankless water heater performs over time. Here are a few habits that help extend its reliability:
– Schedule a service check at least once a year, ideally before the chilly months begin.
– Use a water softener if your home has hard water to prevent mineral buildup.
– Clear any storage or obstacles near the heater to allow airflow and technician access.
– Keep an eye on hot water temperature swings—this can be an early sign of an issue.
– Don’t ignore small warning sounds or blinking lights, even if water is still hot.
In Ball, with the frequent humidity and changing weather, tankless systems need a little extra attention. This helps them stay efficient and ready to deliver hot water when you need it most. Early maintenance avoids last-minute surprises and keeps your home comfortable without interruptions.

Error codes on tankless water heaters are often the first signal that something isn’t quite right. Learning to recognize what they mean and knowing when to act makes a big difference in how long your system lasts. It’s easier to catch problems early when you’re familiar with the signs.
