Navien Tankless Repair FAQs
Why is my Navien tankless water heater not producing hot water?
A Navien unit may stop producing hot water due to ignition failures, flow sensor issues, gas supply problems, scale buildup, or error codes. We offer same-day Navien service throughout Central Indiana.
What Navien error codes do you repair?
We diagnose and repair common Navien error codes throughout Central Indiana, including 003, 012, 038, 110, 351, and many others. If your unit is displaying an error code, call 317-922-9043 for professional diagnosis.
How much does Navien tankless repair cost?
Repair costs vary depending on the issue. We provide upfront pricing before work begins so there are no surprises, and warranty coverage is available on qualifying repairs.
How often should a Navien tankless water heater be flushed?
Most Navien systems should be professionally flushed once per year to remove scale buildup and maintain peak efficiency.
What Does Navien Error Code 003 Mean?
Navien Error Code 003 indicates an ignition failure. This means the unit attempted to ignite but was unable to establish a flame. Common causes include gas supply issues, dirty flame rods, venting problems, or faulty ignition components. Our technicians can quickly diagnose and repair Navien ignition failures.
What Does Navien Error Code 012 Mean?
Navien Error Code 012 indicates flame loss during operation. The burner initially ignited but the flame was not maintained. This can be caused by gas pressure problems, venting restrictions, dirty flame sensors, condensate issues, or component failure. Professional diagnosis is recommended to prevent recurring shutdowns.
What Does Navien Error Code 038 Mean?
Navien Error Code 038 indicates low water pressure within the system. This may be caused by a water supply issue, clogged inlet filter, air in the system, or a malfunctioning pressure sensor. Restoring proper water flow often resolves the problem, but persistent codes should be professionally inspected.
What Does Navien Error Code 110 Mean?
Navien Error Code 110 typically indicates an air pressure or venting issue. Blocked intake or exhaust vents, damaged vent piping, frozen vent terminations, or a faulty air pressure sensor can trigger this code. Proper venting is critical for safe operation and should be inspected by a qualified technician.
What Does Navien Error Code 351 Mean?
Navien Error Code 351 indicates abnormal water pressure in the system. Common causes include high or fluctuating water pressure, a failing pressure-reducing valve or expansion tank, or a faulty sensor. A technician can test your water pressure and find the root cause.
Can I Reset My Navien Water Heater After an Error Code?
Many Navien units can be temporarily reset by pressing the reset button. However, if the error code returns, the underlying problem still exists and should be diagnosed. Repeatedly resetting the unit without addressing the cause can lead to additional damage.
Why Does My Navien Water Heater Keep Showing Error Codes?
Recurring error codes often indicate an unresolved issue such as scale buildup, gas supply problems, venting restrictions, faulty sensors, or failing components. Professional diagnosis can identify the root cause and prevent future breakdowns.
Do All Navien Error Codes Require Service?
Not every error code requires major repairs, but all recurring codes should be investigated. Some codes are caused by simple maintenance issues while others may indicate safety concerns or component failure. Prompt service helps prevent more expensive repairs later.
