What Does Navien Error Code 003 Mean?
Navien Error Code 003 indicates an ignition failure. This means your Navien tankless water heater attempted to ignite but was unable to establish or maintain a flame. This error can be caused by gas supply issues, venting problems, ignition component failures, or dirty flame sensing equipment.
If your Navien water heater is displaying Error Code 003, Hot Water Pros provides professional diagnosis and repair throughout Indianapolis and surrounding communities.
Common Causes Of Navien Error Code 003
The most common causes of Navien Error Code 003 include:
• Dirty flame rod
• Gas supply problems
• Blocked intake or exhaust venting
• Faulty igniter
• Failed gas valve
• Low gas pressure
• Control board issues
• Condensate drainage problems
• Combustion air restrictions
Professional diagnosis is often required to determine the exact cause.
Can I Fix Navien Error Code 003 Myself?
Homeowners can perform a few basic checks before calling for service. Verify that the unit has power, ensure the gas supply valve is open, and confirm there are no obvious vent obstructions.
While a simple reset may temporarily clear the code, recurring Error Code 003 issues typically require professional troubleshooting. Ignition systems, gas pressure, and flame sensing components should be inspected by a qualified technician.
How Do I Reset A Navien Water Heater?
Many Navien tankless water heaters can be reset by pressing the reset button on the control panel. If the error returns after resetting, the underlying issue has not been corrected and additional diagnosis will be required.
Repeatedly resetting the unit without addressing the root cause may lead to additional component damage.
When Should I Call A Professional?
If your Navien water heater continues displaying Error Code 003 after resetting, professional service is recommended. Ignition failures can involve gas pressure issues, venting problems, flame sensing components, ignition systems, or internal controls.

Hot Water Pros did exceptional work for me; they will be my go-to for all future plumbing needs. Cameron and his crew are incredibly thoughtful, responsive, and professional. Their workmanship is first-rate, and their pricing is very competitive. When my 10-year-old water heater started to leak, they took the time to understand my needs and didn’t try to sell me on installing more than what my family and I need or will use. That kind of service is special.
