Testimonial
"Adrian did an excellent job of installing our new Navien water heater. Our prior unit had stopped working. He analyzed the problem and gave us multiple options to address the issue. We decided to replace it rather than replace a part. He was also patient in providing me with complete operating instructions. Very happy with his work!"

Navien Error Codes:

Without proper maintenace your boiler can act up. It's best to schedule, an on-going, annual maintenace for your Navien boiler. If your Navien boiler is displaying these error codes, you must contact a certified boiler Technician to fix the issue. Error codes such as:

  • Ignition Failure (Error Code E003, sometimes E001): It means the boiler is failing to light.
  • Low Water Pressure (Error Code E302, sometimes E002): The system pressure has dropped below the required level for operation.
  • Heat Exchanger Issues (Error Codes E016, E046, sometimes E001, E002, E055): Problems related to the heat exchanger, often involving overheating.
  • Flame Loss (Error Code E012, sometimes E004 - False Flame): The boiler ignites but the flame goes out unexpectedly.
  • Venting, Fan, and Air Pressure Problems (Error Codes E110, E109, E127, E060): Issues related to air intake, exhaust, or the fan motor.
  • Sensor and Control Board Failures (Various Codes like E205, E218, E407, E421, E353, E515, E517, E594, E615): Malfunctions of various sensors (temperature thermistors, water pressure, flow sensor, exhaust sensor) or the main Printed Circuit Board (PCB).
  • Flow Sensor Issues (Sometimes no code, or E439): The flow sensor detects water movement to trigger heating. If it's not working correctly, the unit may not produce hot water even without an error code.
