Navien Tankless Water Heater Repair in the Las Vegas Valley
At Water Heaters Today LLC, we specialize in Navien Tankless Water Heater Repair for Models Such As NPE-A & NPE-S. We stock the specific flow sensors, 3-way valves, and check valves that commonly fail in our mineral-rich water. We don’t just clear the code; we fix the root cause so your endless hot water stays endless.
Keep Your Home's Navien Tankless System in Top Shape
Navien makes the best tankless units on the market, but Las Vegas hard water has a way of finding their weak spots. If your Navien is vibrating, making a “fog horn” noise, or flashing Error 003, you need a specialist who understands the ComfortFlow® system and can repair it.
A Navien is a high-performance computer that burns gas. It requires precise calibration. In Las Vegas, the #1 killer of these units is lack of maintenance. The stainless steel heat exchangers are durable, but the small internal filters and check valves clog easily with calcium.
Water Heaters Today LLC is your local Navien Expert. We know that a “loud vibrating noise” usually isn’t the fan, but it’s also the internal recirculation check valve stuck open by sediment. We don’t waste time; we clean the inlet water filters, flush the heat exchanger, and replace the specific sensors causing your error codes.
Signs Your Navien Tankless Unit Needs Repair
Navien units have a front panel that tells you exactly what is wrong. Before you call, write down the code.
Signs could easily be:
- Error Code 003 (Ignition Failure): The unit tries to light but fails. In Vegas, this is often a dirty flame rod or low gas pressure.
- Error Code 110 (Abnormal Air Pressure): The exhaust venting is blocked, or the air intake filter is clogged with desert dust.
- Vibrating or “Fog Horn” Noise: This is a classic Navien symptom. It almost always means the internal check valve is dirty or broken.
- Cold Water Sandwich: If you get a blast of cold water during a shower, your recirculation pump or flow sensor may be failing.
- Leaking from the Bottom: If water is dripping from the case, the condensate trap may be cracked or clogged.
How We Repair Your Navien Tankless Water Heater
Our repair process is specific to the NPE series technology.
- Error Code Diagnosis: We check the history log to see if the unit has been short-cycling.
- Component Replacement: We carry Navien OEM parts like the 3-way valve, flow sensor, and igniter transformer.
- Descaling Service: We pump food-grade vinegar through the system for 45 minutes to dissolve the rock-hard calcium inside the heat exchanger.
- Filter Cleaning: We pull and clean the Air Intake Filter and the Cold Water Inlet Filter – two 5-minute fixes that solve 50% of “low performance” issues.
Our Commitment to Quality Navien Tankless Services
At Water Heaters Today, we believe in fixing it right or not at all. Our team understands that Navien units are complex.
A general plumber might tell you to replace the whole unit because of a Code 003, but we know it might just need a $20 igniter cleaning.
We use only authentic Navien parts to preserve your 15-Year Heat Exchanger Warranty. With our expertise, your Navien water heater in the Las Vegas Valley will continue to provide the luxury experience you paid for. If your screen is red and flashing, call the pros who know the codes.

Have Any Questions?
Error 003 is “Ignition Failure.” It means the unit attempted to light the gas but failed. This can be caused by a closed gas valve, a dirty igniter, or a fouled flame sensor. We can often clean the sensor to fix this without needing new parts.
If it sounds like a fog horn or a jackhammer, it is likely the internal check valve on the recirculation line. Las Vegas hard water causes mineral buildup on the valve seat, causing it to chatter. We can replace this valve to stop the noise.
In Las Vegas (>180 mg/L hard water), you must flush your unit once a year. If you don’t, scale builds up on the stainless steel heat exchanger, reducing efficiency and eventually causing leaks that void your warranty.
Not necessarily. On Navien NPE-A units, the ComfortFlow® pump might just be turned off or programmed incorrectly. We can check the DIP switches on the circuit board to ensure “Internal Recirculation” is active and set the timer correctly.
We are Navien Specialists. We don’t just install them; we know how to take them apart and put them back together. We carry the specific condensate traps and check valves that fail in our desert climate. While others might leave you waiting for parts, we arrive ready to fix your Error 003 and get your hot water flowing again immediately.
