To this day, an autonomous heating system that works by gas is still popular. Residents of country houses and plots use such devices very actively. This can be said about the owners of apartments in high-rise buildings. This is due to the fact that modern gas heating appliances are characterized by many positive features, they are convenient to use and install, as well as during operation. Having visited the store, you can get acquainted with a large assortment of similar products, but the Navien boiler is the most popular today. Failures can occur during its operation, as is the case with any other equipment. However, you can try to solve the problems yourself by using the error code that appears on the interactive panel.
Most common problems
The Navien boiler, the faults of which can be eliminated by almost every user, sometimes breaks during operation, like any other equipment. This is due to the fact that a low-quality coolant can be used. In order for the consumer to be able to determine the cause and make a decision, the Navien brand boilers give an error code. The following are examples of problems that occur most frequently:
- overheat;
- lack of flame signal;
- open circuit in the temperature sensor;
- damage to the temperature sensor circuit;
- problems in the fan;
- short circuit duct sensor;
- violation of the system;
- control board malfunctions.
You may encounter a problem of overheating of the equipment, as well as a false message about the presence of a flame.
Troubleshooting
If you purchased a Navien boiler, malfunctions can occur during its operation, then you, like every user, need to know the main error codes and options for troubleshooting. Some owners immediately contact the service shop and do it right, since only in this case, when repairing the device, the warranty on the equipment will apply.
If you see error 01 on the display, you should be aware that this malfunction is the most common. It is expressed in a decrease in heating flow or blockage. The same error code also occurs when the circulation pump fails.
You can solve this problem by performing the following manipulations. It is important to check the filter in the heating system for air jams; if necessary, they should be vented. The master needs to make sure that the pump is working properly and that the coil resistance is closed. It is necessary to take care of the efficiency of the impeller, it should not be damaged, and you can find it in the circulation pump.
Error number 02
The Navien boiler, whose malfunctions are displayed, may encounter an error, which is indicated by the numbers 02. If the bypass equipment issues this code, then warm water can flow from the hot tap for a few seconds, then it is cold, and the water temperature rises on the remote control to maximum, then this parameter drops sharply. With heating, in this case, everything can be normal, and the causes of the error sometimes appear due to lack of water or airing of the system.
In some cases, you may notice that the circulation pump works, but does not have the ability to gain the required speed. Sometimes with an error 02, users note that the impeller has mechanical damage. Sometimes the flow sensor in the coolant system does not work, and the heating distribution valve turns off.
Options for resolving error 02
The Navien gas boiler, which malfunctions can become an unpleasant surprise for the user, sometimes gives an error 02. In this case, the master should adjust the pressure, rid the system of excess air, and also analyze the resistance of the pump coil. The impeller must be checked for damage, as in the case described above. The resistance of the flow sensor must be checked for a short circuit, open the distribution valve, and then disassemble the sensor housing, which will allow to clean the flag. The gas boiler "Navien", the malfunctions of which led to the error message 02 on the display, most likely encountered a problem of air congestion. At the same time, the water is in the circuit, it heats up, but after air enters, the temperature drops sharply, it reaches a critical point, which is why error 02 appears on the display.
The occurrence of error 10
Error 10 is issued when the fan is malfunctioning, it may bend, and in some cases the tubes of the air pressure sensor are incorrectly connected. They should lead to fan snails. Sometimes an error 10 is indicated by a clogged chimney or strong gusts of wind.
Ways to solve the problem
Wall-mounted gas boiler "Navien", the malfunctions of which can be indicated by the number 10, must be repaired, which sometimes involves replacing the fan. If necessary, the craftsman should clean the chimney. Make sure that the tubes that lead to the fan coil are connected correctly. They must have an excess.
Noise occurrence
Sometimes users notice that the double-circuit boiler starts to make noise when the hot water is turned on, while the error does not appear on the display. The pressure in the heating circuit can be 1.5 atm, and the solution to the problem is to use a high-quality coolant that can not lead to damage to the heat exchanger. If you still encounter this problem, then the heat exchanger must be removed and cleaned, if necessary replaced with a new one.
Error 011
Malfunctions of the Navien Ice boiler are sometimes accompanied by an error in the form 011. It indicates that the coolant is full. If you have purchased equipment designed for the European market, then such an error may occur, but for adapted boilers it is not possible.
Conclusion
“Navien” - boilers, the fault codes of which were listed above, are characterized by reliability, ease of operation and installation, as well as versatility and safety. These qualitative characteristics often force consumers to choose similar devices for providing housing with hot water and arranging a heating system.
