Frequently Asked Questions

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. Our technicians can quickly diagnose and repair the issue.

What Navien error codes do you repair?

We diagnose and repair common Navien error codes including 003, 012, 038, 110, 351, and many others. If your unit is displaying an error code, call us for professional diagnosis

How much does Navien tankless water heater repair cost?

Repair costs vary depending on the issue. We provide upfront pricing before work begins so there are no surprises.

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 an abnormal water filling condition. This code is commonly associated with the automatic fill system, water pressure issues, or a faulty sensor. A technician can determine whether the issue is related to water supply, controls, or internal components.

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.

The plumbing services provided by Hot Water are best in class. They are extremely professional experts who show up same / next day and provide top quality services.

Jen W.

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.

Cameron is one of the best contractors I have ever worked with. He’s extremely responsive, trustworthy and communicative. I use him at my personal home and recommend him to all of my clients. I cannot say enough good things about Hot Water Pros!!
