Tankless Water Heater Repair in Goose Creek, SC

Common Tankless Water Heater Problems We Fix

Tankless water heaters offer incredible efficiency and endless hot water, but like any sophisticated appliance, they can encounter issues. Our experienced technicians are adept at diagnosing and repairing a wide range of tankless water heater problems common in Goose Creek homes:

No Hot Water or Inconsistent Hot Water

This is perhaps the most frustrating issue. A lack of hot water can stem from various causes, including issues with the flow sensor not detecting water demand, a faulty igniter preventing the burner from firing, or a clogged heat exchanger limiting heat transfer. Inconsistent temperatures might indicate problems with the unit's modulation or flow rate. Our team quickly pinpoints the exact component disrupting to restore a steady supply of hot water.

Persistent Error Codes

Modern tankless water heaters use sophisticated sensors to monitor their operation and will display error codes when a problem is detected. While the specific codes vary by manufacturer (such as Rinnai, Noritz, or Rheem), they often point to issues like:

1. Ignition Failures (e.g., Error 11): Indicates the unit tried to ignite but failed, often due to gas supply issues, a dirty igniter, or a faulty flame sensor.
2. Overheat Protection (e.g., Error 12): The unit has reached an unsafe temperature, potentially due to restricted water flow or a malfunctioning thermistor.
3. Ventilation Issues (e.g., Error 90): Suggests problems with the exhaust system, such as a blockage or improper venting, which can be a serious safety concern.
4. Flow/Water Pressure Problems (e.g., Error 14): The unit isn't detecting sufficient water flow to activate, which could be due to clogged filters, low home water pressure, or issues with the flow sensor.

While some codes might indicate simple fixes, many require professional diagnostic tools and expertise to identify the root cause safely and effectively. Our technicians are trained to interpret these codes and perform the necessary repairs.

Fluctuating Water Temperature

Experiencing sudden bursts of cold water during a shower? Fluctuating temperatures can be a sign of mineral buildup inside the heat exchanger, a malfunctioning thermistor (temperature sensor), or an inconsistent water flow rate. Sediment and scale accumulation are particularly common in areas with hard water, like parts of Goose Creek, and can severely impact the unit's efficiency and temperature stability.

Strange Noises (Banging, Popping, Gurgling)

Unusual sounds emanating from your tankless unit are often indicators of underlying issues. Banging or popping noises, sometimes referred to as "kettling," usually signify significant mineral buildup inside the heat exchanger, which restricts water flow and causes steam bubbles to form and collapse. Gurgling sounds might point to issues with condensation drainage or air trapped in the system.

Leaking Unit

Any leak, no matter how small, should be addressed immediately. Leaks can originate from pressure relief valves, faulty connections, a cracked heat exchanger (often due to freezing if not properly protected), or internal component failures. Our team can quickly locate the source of the leak and provide a lasting repair to prevent water damage and further complications.

Low Water Pressure from the Unit

If your overall home water pressure is fine, but it drops significantly when using hot water from the tankless unit, it could indicate a restriction within the unit itself. This is frequently caused by excessive sediment buildup in the heat exchanger or a clogged inlet filter, impeding water flow through the system.

Foul Odors

A sulfuric or rotten egg smell usually indicates a build-up of sulfur bacteria within the water supply itself, often associated with your water source rather than the unit's fault. However, if you detect the smell of natural gas, it is crucial to immediately turn off your gas supply, ventilate the area, and contact a professional immediately for a potential gas leak. Our technicians are trained to handle gas-related issues safely and effectively.
