Prioritizing Regular Maintenance

Failing to regularly maintain a tankless water heater can not only void your warranty but also drastically shorten its lifespan and significantly decrease its efficiency. At Aaron Services, we understand the importance of proper maintenance to ensure your tankless water heater operates at its best. When properly maintained, tankless water heaters provide energy savings and endless hot water. However, just like a car or an air conditioner, regular maintenance is necessary to keep your system running smoothly and efficiently. Trust us to prioritize the regular maintenance of your tankless water heater, preserving its performance and protecting your investment for years to come.

While Navien and Rinnai tankless water heaters are renowned for their reliability, occasional error codes may arise, indicating potential issues with the system. Here are five other possible error codes you may encounter:

  1. Navien Error Code 001: This code typically indicates a flow sensor issue, suggesting a problem with water flow through the unit. It may require inspection and potential replacement of the flow sensor by a certified professional.
  2. Rinnai Error Code 11: This error code signifies a problem with the ignition or incomplete combustion. It could be due to issues with the gas supply, ignition system, or venting. Professional diagnosis and repair are necessary to resolve this issue safely.
  3. Navien Error Code 108: This code indicates a problem with the fan motor, which may result in inadequate ventilation or airflow within the unit. It’s essential to address this issue promptly to prevent further damage to the system.
  4. Rinnai Error Code 79: This code indicates a communication error between the control board and the burner assembly. It may require troubleshooting of electrical connections or replacement of faulty components by a qualified technician.
  5. Navien Error Code 200: This code typically indicates an overheating issue within the unit, potentially caused by restricted airflow, blockages, or malfunctioning components. Immediate attention from a professional is necessary to prevent damage to the unit and ensure safe operation.

If you encounter any of these error codes on your Navien or Rinnai tankless water heater, don’t hesitate to contact Aaron Services for expert diagnosis and repair. Our certified professionals have the knowledge and experience to address these issues promptly and effectively, ensuring your system operates flawlessly.

Tankless water heaters are rapidly becoming the new standard in water heating due to their energy efficiency, endless hot water supply, and compact design.

However, the efficiency and performance of a tankless water heater heavily depend on a quality installation. At Aaron Services, our certified and experienced technicians ensure your tankless unit is installed correctly and operates at peak performance.
