Understanding Error Code 110
Error code 110 in Navien water heaters indicates a significant issue affecting the unit’s performance. This code can disrupt your hot water supply, making it crucial to identify and resolve the underlying problems.
Common Causes of Error Code 110
- Gas Supply Problems: Insufficient gas pressure can prevent the burner from igniting, leading to error code 110. Check your gas line and ensure it’s properly connected and supplying gas.
- Blocked Venting: Obstructions in the venting system can restrict airflow, causing the unit to malfunction. Inspect the vent for blockages such as dirt or debris.
- Faulty Components: Damaged parts like the gas valve or ignition control board can trigger this error. Testing these components with a multimeter can help determine their functionality.
- Flame Sensor Issues: A dirty or defective flame sensor can prevent proper ignition. Regular cleaning can help maintain its efficiency.
- Temperature Sensor Failures: A malfunctioning temperature sensor can misread readings, leading to incorrect operation. Ensure it’s clean and connected properly.
- No Hot Water: The primary symptom is the absence of hot water when required, which often leads to frustration during daily routines.
- Flashing Error Code: The display will show error code 110, indicating that the unit has detected a problem.
- Unusual Noises: Listen for unusual sounds like clicking or whistling that can signal malfunctioning components.
- Inconsistent Temperature: Fluctuating water temperatures can occur, indicating potential sensor or heating issues.
- None or Weak Ignition: If the burner fails to ignite or produces a weak flame, it may lead to the onset of this error.
By understanding the common causes and symptoms of error code 110, you can take the necessary steps to address the situation and restore your water heater’s performance.
Troubleshooting Navien Water Heater Error Code 110
Error code 110 in your Navien water heater indicates significant issues affecting the unit’s performance, often resulting in no hot water. Follow these troubleshooting steps to identify and potentially fix the problem.
Step-by-Step Troubleshooting Guide
- Check the Power Supply
Inspect the power source. Ensure the unit is plugged in and receiving power. Look for tripped circuit breakers. - Assess the Gas Supply
Confirm that the gas valve is open. If you use natural gas, ensure there’s a steady supply. Listen for a hissing sound which might indicate a leak. - Inspect Venting Conditions
Examine the vent pipe for blockages. Clear away any debris, snow, or ice that might obstruct airflow. - Inspect Flame and Temperature Sensors
Clean the flame sensor with a soft cloth. A dirty flame sensor can cause the unit to shut down. Check the temperature sensor for corrosion or damage. - Examine Error Code Display
Refer to your manual for specific error codes. If other codes appear alongside 110, they might relate to the same issue. - Listen for Noises
Note any unusual noises such as clicking or banging. These sounds might indicate issues with ignition or other components. - Reset the Unit
Power off the water heater for a few minutes, then turn it back on. This may clear minor glitches.
When to Contact a Professional
If you’ve tried the steps above but the error code 110 persists, consider reaching out to a qualified technician. Signs that it’s time to call a professional include:
- Persistent Error Messages
If the error code keeps reappearing after troubleshooting. - Physical Damage
Noticeable damage to components or wiring. - Unusual Smells or Sounds
Any gas or burning odor indicates potential hazards. - Lack of Experience
If you’re unsure about performing further diagnostics or repairs, a professional can provide safety and expertise.
Taking timely action ensures your Navien water heater functions efficiently, restoring your hot water supply.
Preventing Future Error Code 110 Issues
Maintaining your Navien water heater can significantly reduce the likelihood of encountering error code 110. Here are several practical tips to help keep your unit running smoothly:
