Malfunction of boilers. The boiler "Navyen": error "03". Navien boiler: basic error codes

Today not only residents of country houses, but also property owners in the city limits continue to use an autonomous gas heating system. This is due to the positive features of modern instruments, the ease of operation and the convenience of their installation.

Among the huge assortment of such products, the Navyen boilers are in demand, but even such devices can be difficult to work with, error codes will help you to understand them. They will be discussed below. Despite the fact that the manufacturer gives a fairly long warranty, breakdowns are still possible, they sometimes happen in the system. But, as practice shows, with the right approach, they are easily eliminated.

Frequent boiler failures

If during the operation of the equipment an error "03" was issued, the boiler "Navien" should be tried to return to normal operation. Any equipment (here you can include and what is described in the article) sooner or later becomes defective. This may be due to improper installation or non-observance of the operating rules. Sometimes, poor quality of the coolant results in damage to the devices.

In order for the user to determine the cause and make the right decision, the manufacturer has provided a display for which error codes are output. Below you will find the most common problems that can occur during operation. Many users claim that the most common error is "03". The boiler "Navien", however, can give out other codes. For example, the overheating of equipment is indicated by the designation "01E". The figure changes to "02" if the coolant level is too low. The same code may indicate that the flow sensor circuit was broken. If the error is "03" on the display, the boiler "Navien" does not receive a signal about the flame. The figure "04" indicates that a false flame message has occurred. In the temperature sensor, an open circuit may occur, as indicated by the error "05".

In the system of hot water supply, too, there may be certain difficulties, for example, the sensor circuit may be broken, as indicated by the error "07". Sometimes the fan is also experiencing problems in operation, this is indicated by the error "09", but if the smoke removal system fails, you will see the figure "10" on the display. The passage sensor sometimes encounters a short circuit problem, in which case the error is indicated by the number "13", but the closure or breakage of the sensor circuit, indicating an incorrect air pressure, will be indicated by the number "27". Malfunctions of the control board or a malfunction in the operation of the entire system may be indicated by the number "15".

More about "03" error

If a problem arises before you, which is expressed by the fact that the equipment produces error "03", the boiler "Navien" must be returned to normal operation. If you notice that "03" appears on the display, you can be sure that the device has not received a flame signal. As a cause of this problem, one can distinguish the absence of gas supply, as well as the failure of the ionization sensor. Sometimes there is simply no ignition, or the tap is closed. In some cases, the device grounding is malfunctioning.

To solve this problem, it is necessary to clean the blockage on the flame sensor. If you notice a gray coating on the electrode, then you need to get rid of it. For this, fine sandpaper is used, with which it is necessary to clean the surface.

Recommendations for fixing some problems by basic error codes

If you purchased a gas boiler "Navien", the error "03" is not the only code that can be issued by the display. When this or that code appears, you need to contact a specialist for help. They can troubleshoot or advise the user. However, some owners try to identify the malfunction themselves and bring the equipment into working order.

For example, if a "01" error occurred, then a reduction in the flow or clogging in the heating system can be considered as a cause. Sometimes this is indicated by the failure of the circulation pump. To independently exit the situation, it is necessary to check the filter of the heating system for air. The easiest solution would be the bleeding of the plugs. The next step is to check the efficiency of the pump and the coil for resistance. Sometimes the impeller of the circulation pump is damaged.

Solving the problem with error "02"

It is enough in many houses today you can meet the boiler "Navien". Error "03" (how to eliminate it, was mentioned above), occurs as often as error "02". In this case, warm water can flow from the hot tap, which changes to a cold water after a few seconds. On the panel at this time, the temperature can rise to a maximum, and then drop sharply. Users at the same time note that everything is normal with the heating system.

The reasons may be:

• Lack of water;
• Failure of the passage sensor;
• System blown-up;
• Absence of possibility to collect nominal turns by the circulation pump.

Sometimes the heating distribution valve is simply closed. To solve this problem, you should adjust the pressure, see the resistance of the coil and bleed the air from the system. In this problem, as in the above, the cause may be a failed impeller. Before starting the heating equipment, it is necessary to study the faults of the Navien boiler, the error "03" is not the only problem that arises when the device functions.

If you notice "02" on the display, you can open the distribution valve of the unit, and then disassemble the sensor housing. This will clear the checkbox. Experts argue that in this case the problem can arise due to an airlock, which is most likely. The water in the circuit is heated, but after the air enters the temperature rises to a critical temperature, which gives an error of "02".

Solving the problem with error "10"

Sometimes the Navyen boiler produces an error of "03", but in some cases you may notice that the code "10" appears on the display. This can occur due to a malfunction of the fan. Pipes may be damaged or incorrectly connected. They must go from the fan coil to the pressure sensor. Sometimes, to the error "10" leads to the clogging of the chimney. However, in some cases, strong gusts may cause the boiler to issue the above error. Malfunctions can be eliminated by replacing or repairing the fan. The chimney should be cleaned, but first check it. The tubes from the sensor must be connected correctly, it is important to exclude kinks, if any.

Extraneous noise without errors

If you, too, decided to purchase the boiler "Navien", the error "03", the reason of which was mentioned above, may arise from you. But sometimes the operation of the equipment is accompanied by extraneous noise, which is not normal, but the display does not produce errors.

When turning on hot water, you can hear a buzz. This situation, it must be admitted, occurs quite often. It is caused by the fact that the heat exchanger is clogged, this is a consequence of the use of a poor-quality coolant. If you are faced with this situation, the heat exchanger must be replaced, but at least clean it for the beginning.

Error "05"

One of the most popular in the modern market is a gas boiler "Navien", faults (error "03" can be indicated) can be eliminated on its own. For example, if "05" appears on the display, this may indicate a break in the temperature sensor circuit. This indicates that there is a poor contact between the controller and the sensor. A short circuit may occur on the same section.

The consumer needs to check if there is resistance on the circuit from the sensor to the controller to solve the problem. If you find a malfunction, you can replace the sensor. As an alternative solution, a method is used in which it is necessary to disconnect and then reconnect the sensor and controller connectors. Sometimes such an approach helps.

Problem with lack of hot water

You may find that the boiler does not supply hot water. It warms it for heating as it should, but does not serve for hot water supply. The problem in this case is expressed in a three-way valve. Repair or clean it is not necessary, the part should simply be changed. This problem is not rare, because the normal valve life is only 4 years.

Conclusion

When you operate the equipment, you may also have an error "03" on the boiler "Navien". What to do in this case, you should now know, as you have read the information that is outlined above. But it is worth acknowledging that these devices are economical and reliable. If you use them correctly, then the complications are quite rare. But you can solve them if necessary, even without the involvement of specialists in the service department.
