Navien Water Heater Error Code 60: How to Fix It

Q: What causes Navien error code 60 to appear?

Error code 60 is caused by communication failure between the main water heater unit and the remote controller. Common causes include loose wiring connections, damaged communication cables, electrical interference, or controller malfunctions.

Q: Can I still use my Navien water heater with error code 60?

The water heater may still provide hot water, but you won't be able to control temperature settings or access system functions through the remote controller. This limits your ability to optimize performance and monitor system status.

Q: How much does it cost to fix Navien error code 60?

If the issue is loose connections, the fix is free. A communication cable replacement typically costs $50-150 including labor. Remote controller replacement ranges from $200-400 if the controller itself is faulty.

Q: Will error code 60 damage my Navien water heater?

Error code 60 itself won't damage the water heater, but it prevents proper system monitoring and control. This could lead to inefficient operation or inability to detect other system issues if left unresolved.

Q: How long does communication cable last on Navien water heaters?

Communication cables typically last 10-15 years under normal conditions. Exposure to moisture, extreme temperatures, or physical damage can shorten their lifespan significantly.

Abstract

Navien error code 60 (also shown as E060) indicates a communication failure between your water heater unit and its remote controller. This prevents you from adjusting temperature settings and accessing system functions through the remote display.
