Neva heating equipment is one of the most popular among users. The technique of this brand adapted to Russian realities, works stably at reduced pressure in the line. But this does not mean that the operation is complete without breakdowns. Errors of the "Neva Lux" boiler will indicate malfunctions in the system, and their significance will help restore the operation of equipment.
Gas boiler "Neva" is presented in wall and floor version... Single-circuit devices can heat an area of 180 m² and are characterized by low energy consumption. They operate on main and liquefied fuel. Since the combustion chamber is water cooled, connection to an external thermostat is possible. The organization of the chimney is carried out to the main shaft or to the turbo nozzle.
Double-circuit units are represented by the Neva Lux models. The design includes two heat exchangers for heating and hot water supply (DHW). For example, a bithermal radiator is built into the Neva Lux 7224 model. This is a tube in a tube, where water is simultaneously heated for two circuits.
Instrument control is mechanical and electronic. Special sensors monitor the operation of the boiler, in case of malfunctions, they send a signal to the control module. Then the display shows a fault code. To find out its meaning, you can look at the instructions.
We will list the main malfunctions of the device, as well as indicate options for eliminating the problem.

Troubleshooting
For 2 years I have been operating a Neva Lux gas boiler manufactured by Baltgaz. Now defects began to appear in his work. If you use it for a long time hot water, the pressure in the system drops and it stops by error 04. Although the pressure gauge shows the same pressure of 1.6 bar. Has to
constantly use make-up. How can I fix this?
Perhaps the pressure in your expansion tank is lower than it should be. It is then that error 04 is possible.
Six months ago, I installed a double-circuit boiler Neva Lux 8230. Recently I encountered such a problem. When hot water was required, I turned on the tap as usual. At first it went warm, and then cold again. Error 02 appeared on it at that moment. I tried to reset it with the "reset" key, but after that the heating turned on. After that, hot water was required again in the evening. I turned on the tap and everything worked fine. The device worked for 4 days without problems, but today the error appeared again. I studied it more carefully. It happens like this. After the transition to heating water for DHW occurs, a sound is heard inside, similar to air intake. At the same time, you can observe the instability of the manometer readings (approximately 0.5 in each direction). And all this is accompanied by the same strong sound not only from himself, but also from membrane tank(additional, external for 18 liters). After that, the pressure rises sharply to 5 bar. It turns off, the water temperature drops to 23C. And error 02 is displayed. The instructions say that I have air in the heating system, but I work with hot water supply. What's the connection? Maybe my 3-way valve is broken? Or is the filter in the heating system clogged?
Error 02 - the coolant is overheating. The fan may be broken or the sensor is damaged.
My boiler Neva Lux 7023 stops about 2 times a month by error 07. Restarting always solves this problem. And now a new error has appeared - E5. It works for a quarter of an hour and turns off. What happened to him?
Error E7 means that the coolant is too overheated. Perhaps your heat exchanger is covered with scale on the inside, and because of it there is poor circulation in the system. Did he start making some unusual noise with you? But regarding the E5, here you need to pay attention to the pressure switch or the fan. It is necessary to look at both that and that. In an amicable way, this problem should be solved by a specialist. Also, just in case, check if your chimney is icy.
The unit showed error 03. As I understand it, it means problems with the fan. When checking, I applied voltage to it - everything is normal. I also checked the pressure switch - it is also working properly. It turns out a relay on the board? A couple of years ago I came across a similar one. But then an acquaintance helped me out, giving from his old unit. Tell me, is it possible to work somehow without this relay? I tried to manually spin the fan, it started to work, but the gas did not come in. Is the same relay responsible for this? But now the error was 01.
In order for the relay to work longer, you need to set it up more carefully. gas valve and heating power, and it is advisable to install a room thermostat. All this not only increases the service life of the device, but also saves gas. To solve error 01, you need to check the voltage on the gas valve, whether it opens normally and whether gas is flowing. It is better to call a specialist, since all these checks are life-threatening. And the master has a diff. pressure gauge for assessing gas pressure. And so, most likely you have little house and you did not tune the system for the heated area. So a room thermostat is the best solution for you.
Help me please. In our new apartment, even before us, a wall-mounted double-circuit NevaLux 7218 was installed. During the day, it constantly stops by mistake 04. They began to feed, then the temperature began to drop. And now water has also flowed out of it (in the place where the heating pipe enters it). I had to turn it off. So you can't use it?
It is necessary to check the pressure switch. In the chimney, a small air exhaust pipe could be blocked.
My wall-mounted boiler Neva Lux 7023 (Baltgaz) has a problem with hot water supply. With heating, everything is normal, and as soon as I start parsing water, error E2 appears. This does not heat up the water. If the water is turned off, then it is perfectly normal to continue heating the apartment. The water pressure is consistently good. I looked in the instructions, it says that E2 is an error of unsuccessful ignition or overheating of the coolant. During DHW operation, the burner starts working and burns for 2 seconds. Then the thermometer shows a temperature of 95C, immediately turning off the device and an error. The water runs warm while the burner is on. What could have broken?
Try to check the DHW temperature sensor, perhaps this is the case. Although, in theory, the E2 error symbolizes problems with ignition, but then there would be no heating.
My wall-mounted Baltgaz boiler at first did not want to switch from heating system mode to hot water supply. Although, sometimes, for reasons I do not understand, it still worked as it should. First of all, I checked that all contacts were in good working order, then I checked the electric motor of the three-way valve. If you clamp it with a screwdriver, then the valve is in good order and works as it should. If you switch the mode (with the engine removed), then everything works. The movement of the stem is noticeable and consistent. I contacted the service center. The master who came to me suggested that the problem was in the flow sensor. He did not see the signal coming to him. We need a new one. But he did something to make the device work. It did not work for a day, and then I needed to turn it on. And it won't start. The indicator blinks, all possible symbols are highlighted. The reboot did not help. Disconnecting the power supply did not help either. What could be the problem?
Take out the connector on the board, and disconnect the wires one by one. First of all, those that are responsible for the drive of the three-way valve. Then reattach them. This should fix your problem.
I can't fix the boiler in any way Baltgaz neva... Error 03 constantly appears, the fan does not work during ignition. If you blow on the pressure switch tube, then it starts spinning. The device does not want to turn off on its own, you have to do it manually. How to be?
Find the hatch in the upper right corner. You need to open it and restart it.
