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 in your expansion tank the pressure 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 itself, but also from the 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 you have a heat exchanger with inside all in scale, 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 dual-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 boiler produced by Baltgaz, installed on the wall, at first did not want to switch from the mode heating system for 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. Contacted 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 just can't fix the Baltgaz Neva boiler. 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.

Other malfunctions

Lack of spark for ignition.

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

The most expensive boiler Nevalux 8224 is equipped with a built-in storage boiler. When choosing a boiler for heating, if you are satisfied with the Neva Lux 8224 gas boiler, the price of reviews is best obtained from real owners or specialists in gas equipment.

Malfunctions of the gas boiler Neva Lux

The simplest single-circuit and non-volatile model Neva Lux 8618. It completely lacks electronics. A simple gas boiler Neva is very reliable.

The most common malfunctions characteristic of this boiler are as follows:

• very low level gas pressure in the pipeline;
• low pressure due to the presence of air in the circuit;
• extinction of the burner flame;
• mechanical damage to the boiler or heating circuit.

The presence of a control unit with a microprocessor in the Neva Lux 8224 model allows for self-diagnosis of malfunctions that have arisen during the operation of a gas boiler. The electronics that are installed on the gas double-circuit wall-mounted boiler Neva Lux displays malfunctions on the display in the form of an error code.

Display error codes

Any technical device may break. The Neva Lux boiler of any model is no exception. Its stoppage may be due to the failure of any element in the control system or their incorrect operation. The control system displays the error code, and knowledge of the error code makes it easier to detect the malfunction.

The following error codes are displayed:

Error 01. This error indicates unsuccessful ignition. The boiler does not turn on:

Error 02. Overheating of the coolant. The boiler does not work:

Error 03. Lack of traction:

Error 04. Low water pressure in the circuit:

Error 05. Failure of the heating system temperature sensor:

Error 06. Failure of the DHW temperature sensor:

• sensor malfunction;
• open or short circuit of the electrical circuit between the sensor and the electronic board.

Other malfunctions that cannot be shown on the display. For example, if there is no electricity, the boiler will not turn on and will not work. Of course, if you establish, then such a nuisance can be avoided.

Fuse blown. A fuse rarely blows for no reason. If, after replacing it with a similar fuse, it blows again, then you need to find the cause. In no case should you install bugs that can damage the entire boiler electronics.

If the electronic board was accidentally flooded with water. You need to turn off the boiler from the network and dry the board warm air from a hair dryer. Sometimes there may be a malfunction of the electronics. To reset to the initial position, press the RESET button. If it does not help, then disconnect the boiler from the network for a few minutes and turn it on again.

If you smell gas, find and repair the leak immediately.

If you cannot fix the leak yourself, it is recommended to call the gas service by emergency number 104.
