Existing breakdowns in which errors do not appear on the device

If the electronic display of the Neva heating boiler does not show an error code, but the equipment does not turn on, pops are heard, there is a smell of gas, etc., then this may also indicate an existing breakdown of the system. Inspect the boiler, fix the problem, find its description in this article below and fix the problem in time.

It is impossible to turn on the Neva Lux boiler

There is no electricity in the network. Contact your electricity supplier.
The fuse on the board has blown. Its replacement is required.
Moisture has entered the circuit board. To fix, try drying the board with slightly warm air, or remove the board and place it in a dry place for a few days. warm room. It is important that the water completely evaporates.
The electronic board may be damaged. AT this case the reset button won't help. To fix it, you need to disconnect the device from the network and try to turn it on again. If this does not fix the problem, then a new board should be installed.

Pops are heard in the burner

The settings for the minimum gas pressure and ignition power are set incorrectly. Re-adjustment of these parameters is required.
Too poor air supply to the burner. To eliminate it, it is necessary to clean the pipe or channel through which air is supplied.
Problems with a spark from the spark plug electrode. It slips to the edge of the burner section or to the shell of the combustion chamber. To eliminate it, it is necessary to slightly bend the spark plug, or, conversely, move the shell away from the combustion chamber. In this way, you will ensure that a spark enters the area of \u200b\u200bthe nozzle holes of the burner section.
The burner block may be dirty. It needs cleaning.

Troubleshooting

I have been using the Neva Lux gas boiler manufactured by Baltgaz for 2 years. Now in his work began to appear defects. If you use for a long time hot water, the pressure drops in the system and it stops with error 04. Although the pressure gauge shows the same pressure of 1.6 bar. account for
drink constantly. How can I fix this?

Your expansion tank may be under pressure. That's when 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 needed, I opened the faucet as usual. It went warm at first, 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 again required in the evening. Opened the faucet and everything worked fine. The device worked without problems for 4 days, but today the error appeared again. Studied more carefully. It happens like this. After the transition to DHW heating, a sound is heard inside, similar to the suction of air. At the same time, one can observe the instability of the pressure gauge readings (approximately 0.5 in each direction). And all this is accompanied by the same strong sound, not only from itself, but also from the membrane tank (additional, external 18l). After that, the pressure rises sharply already up to 5 bar. Switching 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. What is the connection? Maybe my three way valve is broken? Or is my filter clogged in the heating system itself?

Error 02 - the coolant is overheating. Perhaps the fan is broken or the sensor is damaged.

My Neva Lux 7023 boiler stops about 2 times a month with error 07. A reboot 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 hot. Perhaps you have a heat exchanger with inside all in scale, and because of it, there is poor circulation in the system. Has it started making any unusual noises for you? But about E5, here you need to pay attention to the pressure switch or fan. You have to watch this and that. In a good way, this problem should be solved by a specialist. Also, just in case, check if your chimney is iced up.

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. Also checked the pressure switch - also serviceable. Is it a relay on the board? I ran into something similar a couple of years ago. But then a friend helped me out, giving from his old unit. Tell me, is it possible to somehow work without this relay? I tried to manually spin the fan, it started working, but no gas came out. Is the relay responsible for this? But now the error was 01.

In order for the relay to work longer, you need to more carefully configure gas valve and heating power, and it is also desirable to install a room thermostat. All this not only increases the 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 associated with a risk to life. And the master has a differential. pressure gauge for assessing gas pressure. So, most likely you little house and you did not set up 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 error 04. They began to feed it, then the temperature began to drop. And now water has also flowed from it (in the place where the heating pipe enters it). I had to turn it off. Does that mean they can't be used?

The pressure switch needs to be checked. The chimney could be clogged with a small air duct.

My wall-mounted boiler Neva Lux 7023 (Baltgaz) has a problem with hot water. With heating, everything is normal, and as soon as I start the analysis of water, an E2 error appears. The water does not heat up. If the water is closed, then it continues to heat the apartment quite normally. 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 and burns for 2 seconds. Then the thermometer shows a temperature of 95C, the device immediately turns off and an error occurs. The water is coming warm while the burner burns. What could be broken?

Try to check the DHW temperature sensor, this may be the case. Although, in theory, the E2 error symbolizes problems with ignition, but then there would be no heating.

My boiler manufactured by Baltgaz, installed on the wall, at first did not want to switch from the 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 condition, then I checked the electric motor three-way valve. If you clamp it with a screwdriver, then the valve is in good condition and works as it should. If you switch the mode (with the engine removed), then everything works. Stem movement is noticeable and consistent. Contacted the service center. The master who came to me suggested that the problem was in the duct sensor. He did not see the signal coming to him. Need a new one. But he did something to make the device work. He did not work for a day, and then I needed to turn it on. And it doesn't start. The indicator blinks, all possible characters are highlighted. Reboot didn't help. Disconnected the power - also did not help. What could be the problem?

Remove the connector on the board, and disconnect the wires one by one. First of all, those who are responsible for driving the three-way valve. Then reattach them. This should solve your issue.

I can’t fix the Baltgaz Neva boiler in any way. Error 03 constantly appears, the fan does not work during ignition. If you blow on the tube of the pressure switch, it starts to spin. The device does not want to turn itself off, you have to do it manually. How to be?

Find the hatch in the upper right corner. It needs to be opened and restarted.

Other malfunctions

No spark to ignite.

Faulty or poorly installed spark plug. Correctly install the candle (the gap between the end of the candle and the burner section is 4-5 mm) or replace it. Unreliable contact between the terminal and the ignition wire. Check the contact of the terminal with the ignition wire. Ignition electrode dirty. Wipe the electrode from dust and degrease.

The boiler does not turn on.

Lack of gas. Lack of water. Lack of electricity. Carry out appropriate checks (incoming gas, presence of water, connectors, fuses). Burner nozzles clogged. Clean nozzles.

What are the possible reasons and what to do, we will consider in more detail:

01

Error 01. Malfunctions that occurred during unsuccessful ignition.

Possible reasons:

02

Error 02. Indicates that the boiler has overheated.

Possible reasons:

03

Error 03. In order to fix it, check:

04

Error 04. Low pressure in the heating circuit, you need to check:

Too much decreased pressure in the heating system, raise it to the recommended level.
Possibly in the system formed airlock , use the vent valve to remove it.
Broken pressure sensor in the heating circuit. Replace it.
The pump is broken, clean it and replace if necessary. Spend visual inspection all connections and connectors on the control board.

In the section on the question Boiler Neva Lux 8224. Constant error 03. Condensation accumulates in the pressure switch tubes. How to fix this problem. given by the author Vladimir the best answer is Need more detailed information about where it is located, external temperature, fuel (gas or diesel), winter or summer, etc. And condensate from what (water, gas)?
What can be done to prevent condensation from collecting in the Pitot tubes? The Neva Lux 8224 boiler turns off every year in January, showing error 03. Of course, I eliminate the condensate and start the boiler until the next accumulation of condensate, but this problem is pretty annoying. Help!

Answer from Yotas Shabanov[guru]
1. Check if the faucet is completely closed
make-up.
2. If the make-up valve is closed to the stop, then
it is possible that the feed valve is not tight.
Replace feed tap.
3. Check if the secondary heat exchanger is leaking.
4. Also check if the sensor is working
pressure and connectors of its contacts.
Another option: slightly opening the plug with right side
at the top, in order to enter the combustion chamber
hit warm air and not
condensation formed in the pressure switch tubes.
