Common Tankless Water Heater Issues We Resolve
Tankless water heaters are sophisticated appliances with unique components that can falter over time. Our experienced technicians are equipped to handle the full spectrum of tankless issues, from minor glitches to major system failures. If you are experiencing any of the following problems, we have the expertise to help.
- No Hot Water: The most urgent problem a homeowner can face. This can stem from an ignition failure, a faulty gas valve, a tripped circuit breaker, or a blocked air intake or exhaust vent.
- Intermittent or Fluctuating Water Temperatures: If your water goes from hot to cold during use, it often points to a problem with the flow sensor or a buildup of mineral scale inside the unit that disrupts the heat exchanger's ability to work consistently.
- Low Hot Water Pressure: A noticeable drop in hot water pressure is a classic sign of mineral accumulation. Hard water, common in the Fair Oaks area, causes scale to build up in the heat exchanger and pipes, restricting water flow.
- Strange Noises: Your tankless unit should operate quietly. Loud knocking, rumbling, or gurgling sounds almost always indicate significant scale buildup on the heat exchanger, causing water to boil and steam inside the system.
- The Unit Shuts Itself Off: If your system randomly powers down, it could be a safety mechanism triggered by a problem with the flame sensor, ignition pack, or overheating due to poor ventilation or scale.
- Leaking Water: Leaks can originate from pipe fittings, pressure relief valves, or, in more serious cases, a cracked heat exchanger. Any sign of water requires immediate professional attention to prevent damage.

Understanding Tankless Error Codes
One of the benefits of a modern tankless heater is its ability to self-diagnose. When a problem occurs, your unit will likely display a numeric error code on its digital panel. While these codes are helpful, they often point to a category of problems that requires a professional diagnosis. Our technicians are fluent in the language of error codes for all major brands, including Rinnai, Noritz, Navien, and Rheem. Common codes often indicate issues such as:
- Ignition Failure (e.g., Code 11): The unit tried to light but failed. This could be a gas supply issue, a faulty igniter, or a dirty flame sensor.
- Flame Loss (e.g., Code 12): The burner lit but the flame went out. This might be caused by gas pressure fluctuations or an exhaust blockage.
- Overheating: A code indicating the unit has exceeded a safe temperature, often due to mineral buildup restricting water flow.
- Ventilation or Air Supply Problem: The system has detected an issue with its intake or exhaust, a critical safety concern.
Our Comprehensive Tankless Repair Process
We follow a systematic process designed to deliver an accurate diagnosis and a durable repair, ensuring your complete confidence from start to finish.
- Thorough System Diagnosis: Our technician begins with a comprehensive inspection of your tankless water heater. This includes checking for error codes, testing electrical components, inspecting gas and water connections, and assessing the condition of the heat exchanger and ventilation system.

- Expert and Efficient Repair: With your approval, our technician will perform the repair using high-quality parts and industry-best practices. Our service vehicles are stocked with the most common components needed for tankless repairs, allowing us to complete most jobs in a single visit.
- Final System Testing and Verification: After the repair is complete, we don’t just leave. We thoroughly test the unit to ensure it is heating water correctly, operating safely, and performing at peak efficiency. We verify that the original problem is fully resolved.
Repair or Replace? Honest Guidance for Fair Oaks Homeowners
A common question is whether it’s more cost-effective to repair an existing tankless unit or invest in a new one. With a lifespan of up to 20 years or more, most tankless heaters are worth repairing. We provide honest advice based on several key factors:
- Age of the Unit: If your unit is less than 10-12 years old, repair is almost always the most sensible option.
- Cost of the Repair: We weigh the cost of the current repair against the price of a new installation. A minor repair is an easy choice, while a major component failure like a cracked heat exchanger on an older unit may lean toward replacement.
- Frequency of Past Repairs: If your unit has required multiple service calls in the last year, it may be nearing the end of its reliable service life.
- Performance and Efficiency: An older, inefficient unit that is constantly struggling due to hard water damage may be a candidate for replacement with a newer, more efficient model.
Our goal is to provide the information you need to make the best decision for your home and budget, whether that's a dependable repair or a strategic upgrade.
