Navien boilers are widely known in the heating equipment market.
There are several reasons for this: versatility (they can be installed in a private house or apartment, as well as in non-residential premises), quality, automation of the boiler operation process and, at the same time, an affordable price. But any equipment can sometimes fail. And the fault here is not at all in the quality of the boiler itself. Is your Navien boiler showing an error on the display? Often problems are associated with incorrect installation, irregularities during operation, lack of service or its low level and other factors. Therefore, Navien boiler errors may appear on the screen periodically.
The main thing is to know what the error codes of Navien boilers mean in order to assess the situation and find a solution to the problem. Read the error codes of Navien boilers, the reasons for their occurrence and possible solutions from specialists below.
Error 02
Error 02 indicates that the Navien boiler has a low coolant level. Or there is a problem with the flow sensor. As a rule, when the Navien boiler gives error 02, boiling water comes out of the hot water tap for the first seconds, and then cold water. That is, the water temperature suddenly becomes maximum and also drops sharply.
How to fix error 02
1. Adjust the pressure in the heating system. 2. If there is excess air, bleed it through a special valve. 3. If the problem occurs due to a closed distribution valve, open it. 4. Check the functionality of the flow sensor.
Models
Knowing the general characteristics of the system, of course, will not be enough.
You should also understand the specifics of its individual versions. Thus, “Ace K 13,” according to the manufacturer, harmoniously combines considerations of convenience and aesthetics. When developing the model, it was taken into account that a variety of people have a need for it, and thanks to the efforts of specialists, it was possible to create a true leader in the price group. This modification is supplied to a variety of countries in Europe and Asia, and everywhere it causes predominantly positive emotions. The main concept that the designers adhered to was to ensure the highest level of reliability that is possible for modern technology.
The manufacturer indicates that this boiler should only be installed in rooms with a total area of 130 sq. m. m.
The closed type of the firebox allows you to avoid special boiler rooms when installing the device:
- in bathrooms;
- in kitchens;
- in the bathrooms;
- in other areas of the house of your choice.
The boiler will reliably warm up the house even at very low temperatures outside. It will not be hindered by either insufficient water quality or power surges in the electrical network. If any problems arise, the assistance of the service center will not be long in coming. A problem typical for the Russian climate, such as freezing of the coolant during cold weather, has been solved.
In an hour, 1.33 cubic meters will be consumed. m of natural or 1.16 kg of liquefied gas, while the heating of the coolant will reach 30-60 degrees, water will enter the water supply circuit at a temperature of 40 to 80 degrees.
A more powerful option is the Ace 24 floor-standing boiler. In the manufacture of all its parts, the requirements of the ISO 9001 standard are strictly observed. The boiler is made using a turbine design, like the previous version, and does not require a dedicated room.
Error 09
Error 09 of the Navien boiler notifies about problems (failures) in the operation of the fan. The fan motor may be faulty. Another reason is a malfunction of the control board.
How to resolve error 09
1. Check the fan motor for short circuit or open circuit. 2. If necessary, replace the fan. 3. If the problem is a control board failure, try restarting the boiler. If it doesn't help, change the board. 4. Check the voltage in the fan motor. And the voltage in the electrical network. If it is higher than normal, use a voltage stabilizer
Repair
To remove the transformer, you must:
- disconnect the connector by pressing the lock;
- Carefully remove the ignition electrodes.
Connection occurs in reverse order:
- first the electrodes are connected;
- then the connector is fixed.
Now you can reconnect the power supply and turn on the boiler in operating mode. The pump turned on, the fan started and a spark occurred.
Turn off the boiler again and turn off the power supply. We connect the electrodes to the boiler firebox. It is important to do this very carefully so as not to damage the gasket.
Error 10
Error 10 of the Navien boiler indicates a malfunction of the smoke removal system. It may be a clogged chimney, a bend in the tubes from the air pressure sensor, or an incorrect connection. Another possible reason for this error to appear is strong gusts of wind.
How to resolve error 10
1. Check, repair or replace the fan. 2. Check and clean the chimney, if necessary. 3. Check how the tubes from the air sensor are connected. Avoid any kinks.
Decoding the code
The boiler instructions say briefly: fan malfunction. An unambiguous interpretation – failure – is incorrect. Error 09 is not necessarily caused by a breakdown of the device: its incorrect operation is also the cause of emergency blocking of Navien.
The control panel is not built into Korean boilers. Testing of the unit and setting parameters is done from the remote control. Errors also appear on its display. Once you know what the buttons do, it's easy to follow the steps below.
Step 1
Restart Navien. Imported equipment, unlike domestic boilers, reacts to power supply problems. And we have enough of them, from phase imbalances to low voltage. The electronic circuit records this as a malfunction and blocks the operation of the heating unit. If error 09 is caused by this reason, it will disappear after resetting.

Step 2
Check connections. There are two wires connected to the Navien boiler fan. An open circuit, a short circuit, unreliable contact - and error 09 is guaranteed.
Check the wire contacts on the Navien fan
Step 3
Measure the voltage. The norm for the Navien boiler is 230/1f, maximum deviation 10%.
Step 4
Check the fan. When turned on, its blades must rotate at a speed of at least 400 rpm. Otherwise, even before ignition, the automation will react and block the Navien boiler with error 09. Testing is carried out by lightly touching the impeller. Normal rotation indicates that the mechanical part of the fan is working properly.

Probable Causes
- Insufficient speed due to interturn short circuit or problems with kinematics. If the problem is in the winding, the fan is replaced, and after service, error 09 disappears. Incorrect operation of the device is caused by a number of factors.
- Blade contamination. The fan unit needs to be removed and cleaned.
- Bearing failure. It can be changed independently; shaft alignment is not required.
No rotation. If voltage is supplied to the Navien boiler fan, there are no complaints about the mechanics, but the impeller is motionless, the problem is in the winding. Its resistance is in the range of 23–25 Ohms. When R = 0 – short circuit, = ∞ – open circuit: the fan unit is replaced.
Step 5
Replace the Navien boiler board. If previous actions did not produce results, then this is the cause of error 09. It generates fault codes based on signals received from sensors.

Useful tips
The occurrence of false boiler errors caused by the supply voltage can be eliminated by connecting Navien to the network via a UPS. Not everyone understands the difference between this block and the stabilizer. For a Korean unit, the latter is not needed - the heating installation has its own built-in and efficient circuit. In addition, if there are breaks in the line or problems with the gas generator, this device will not help - the Navien boiler will stop. But the UPS (stabilizer + charger + batteries) will provide long-term operation in autonomous mode until problems with power supply/voltage are eliminated.
When calling a service representative, you should make sure that the organization is a regional division of Navien or is certified by the manufacturer. If this is just a workshop for repairing heating equipment, problems are possible: lack of diagrams, guidelines for eliminating errors, spare parts, and trained specialists. The result is delays and poor quality service.
Error 16
The Navien boiler issues error 16 when the heating equipment overheats. The sensor is triggered by overheating and blocks the operation of the boiler. The problem may be a malfunction of the sensor itself.
How to resolve error 16
1. Allow the boiler to cool down and restart it. 2. If the problem is a lack of water in the heating system, add it. 3. If the sensor itself is faulty, replace it. 4. Check the operation of the three-way valve. In case of malfunction, replace the tap. 5. Restart the boiler. It might be the control board. It may be necessary to replace the board.
Self-diagnosis of Navien boilers
The self-diagnosis system guides the user to timely identification of faults in Navien. The electronic unit interrogates all sensors, analyzes the received data, and displays critical failures on the LCD display in the form of digital symbols. Practical guidance on troubleshooting is given in the technical documentation.
With the latest digital modifications, the monitor is located on the control panel. The codes are clearly visible even in the dark, due to the presence of bright multi-colored LED backlighting.
For different Navien boilers, information is presented in both digital and alphanumeric characters. There is absolutely no difference between failure “10” and “E10”.
Error 27
Error 27 informs about an open or short circuit in the APS air pressure sensor circuit.
How to resolve error 27
1. Check the APS air pressure sensor.
If a circuit fault is detected, replace the APS sensor. 2. If there is no commutation between the APS sensor contacts and the control unit connector, disconnect the APS sensor connector from the control unit connector connector, and then connect them again for normal contact. 3. If the control board is faulty or does not work correctly, restart the boiler; if it fails again, replace the control board. Now you know the error codes that a navien boiler can produce.

Causes of Navien boiler malfunctions
Any malfunctions of Navien boilers that are under warranty must be carried out by a service organization.
Before visiting a service organization, the consumer needs to turn on the diagnostic system, analyze the probable causes of the failure and evaluate the possibility of repair.
Error codes in Navien boilers are classified according to 3 structural elements:
- leaks in the heating circuit;
- the ignition system does not work;
- low parameters in the gas network.
Not all errors require the participation of service specialists. For example, the absence of a torch in a piezo igniter can be caused by a failure of the primary flame sensor, zero gas fuel pressure in the line, when the head valve is mistakenly closed, or in the event of a faulty ground loop.
Therefore, troubleshooting begins with inspecting the primary sensor, which must be clean and without damage. After cleaning the surface of the primary sensor, the boiler operation is checked again.
Procedure
Reboot
First you need to restart the gas heater using the mains switch using the remote control. The South Korean company's products are resistant to unstable voltage, but if its value deviates significantly from the nominal voltage, a false fault may be displayed.

If the reboot does not produce results, then the problem is in the device itself.
Checking signal lines
The malfunction is easily identified by visual inspection after removing part of the housing. Error 13 can be caused by:
- melted insulation;
- unreliable contacts;
- short circuit;
- broken wires.
Inspection and troubleshooting will take very little time.
User manual
Navien gas boilers are operated automatically, with minimal human intervention.
The owner only needs to observe the readings on the display and respond in a timely manner to the appearance of an error code.
In addition, the user determines the operating mode - summer or winter:
- Summer mode is determined only by DHW heating.
- Winter mode starts the heating system simultaneously with the supply of hot water.
The display has a button with a corresponding icon (indicating a snowflake or a sun).
If it is necessary to adjust the extract air temperature or other parameters of the heating system, the winter operating mode must be turned on. Exhaust temperature is adjusted when the radiator icon is flashing.
If it lights up steadily, the display shows the current temperature. By pressing the “radiator” button so that the icon flashes, press the “+” or “-” buttons to change the set coolant temperature.
The icon stops flashing after a while (a few seconds), and the boiler will begin to heat or cool the coolant in accordance with the instructions received.

Rules of operation and timely maintenance
When purchasing a gas unit to heat your apartment or private home, you should remember that modern devices belong to the category of complex, high-tech, full of automation and protective systems. Therefore, in order to extend the life of the boiler and prevent its premature failure, it is necessary to follow certain operating rules.
- Firstly, this is installation in accordance with established requirements, according to the scheme recommended by the manufacturer, and not based on the advice of a familiar master.
- Secondly, these are high-quality materials and components: savings at this stage threaten to develop into financial costs for boiler repairs in the future.
- Thirdly, this is a thorough check of the condition of the sensors, chimney, water/gas supply before starting the boiler. Inspection and cleaning of main components should be done regularly, and not occasionally.
The automation will tell you the probable causes of problems by displaying coded messages on the display. Experience shows that following these recommendations will help avoid possible serious breakdowns and failures, which means that owners will not have to find out what typical malfunctions the Navienace boiler has and what will be required to eliminate them.

Possible defects
The sensor grounding wire (housing) requires special attention A feature of the Navien boiler circuit, which not everyone knows about, is the inclusion of resistance in this circuit. It happens that the resistor burns out , the line breaks, and error 03 is displayed. You can check for integrity with a multimeter: when measuring, the device should show R within 0.5 MOhm.

Gas valve
Error 03 is triggered by a problem with one of the 3 coils. As a rule, modulation has nothing to do with it: combustion of its winding is an exceptional case. But two shut-off valves in Navien boilers sometimes fail.

Useful tips
- When contacting a service center, you need to choose the right organization. If it is not certified by a Navien representative, problems will arise. The lack of qualified craftsmen, manuals, diagrams, and spare parts will lead to protracted repairs. And the price for the parts necessary to restore the boiler’s functionality is higher - there are no direct connections with the manufacturer.
- Recommendations from managers and home-grown experts on turning on Navien through a stabilizer make a professional smile. The Korean boiler has its own scheme. Only a UPS will ensure the operation of the unit even if there is a power failure on the line. The stabilizer is powerless in this case, and the autonomous unit will help out due to built-in (or plug-in) batteries, charging devices and smoothing out pulsations.

Line diagnostics
A problem with the gas supply to the Navien boiler is expressed in a blockage of the path or low pressure. The method for searching for the “culprit” of error 03 depends on the connection diagram of the unit to the main line or tank with “blue fuel”. If the building has a gas stove, the task is simplified . You can determine if there are problems in the pipeline by igniting the burner.
p, blockquote 5,0,0,0,0 —>
It is also easy to check the pressure by turning on all of them: by the intensity of the flames and their stability, it will become clear whether it is sufficient for the normal functioning of the equipment. For gas boilers, and Navien is no exception, there is a lower response threshold. And if gas flows, but the pressure in the line is below critical, error 03 is inevitable.

Counter
non-working meter also causes error 03 of the Navien boiler. It is sealed, but the user can verify its normal functioning visually. You need to try to turn on some kind of gas appliance to ensure the consumption of “blue fuel”.

Filter
Its mesh needs regular cleaning . During operation of the Navien boiler, the cells become clogged with ice and other solid fractions deposited along the pipe. Pulling the mesh out of the glass, rinsing it and putting it back in place takes just a few minutes.

Storage tank
With an autonomous gas supply, the Navien boiler is connected to a gas holder or cylinder group. If we are not talking about maximum fuel consumption, the cause of error 03 is the gearbox. Typical faults: icing or dirt blocking the channel. In any case, solving the problem is not difficult.
