Troubleshooting

For 2 years I have been using a Neva Lux gas boiler manufactured by Baltgaz. Now defects began to appear in his work. If you use hot water for a long time, the pressure in the system drops, and it stops by mistake 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. This is 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 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. Shutdown occurs, 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 may be 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. Has he started making some unusual noise for 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 serviceable. Is there 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 no gas came. Is the same relay responsible for this? But now the error was 01.

In order for the relay to work longer, it is necessary to adjust the gas valve and heating power more carefully, and it is also 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, as all these checks are life-threatening. And the master has a differential. pressure gauge for assessing gas pressure. And so, most likely you have a small 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 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, an 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 doesn'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.

What does error 01 mean, how to troubleshoot the Neva Lux repair?

Double-circuit gas boilers Neva Lux 8624, 8230, 8224 are wall-mounted apparatus with forced circulation of the coolant (water or antifreeze). Repair and maintenance of Neva Lux boilers is carried out according to the service instructions by a specialized service organization that is also engaged in the installation, commissioning and service work with the supply, replacement of faulty parts with new parts of this Neva Lux heating equipment.

So, with error 01, the flame does not ignite in the combustion chamber or the ignition starts, but it turns out to be unsuccessful - the Neva boiler does not work. Concisely, in this case, one or several reasons for error 01 may be present. Let us consider all the causes of the emergency and give a full range of recommendations for repairing the Neva Lux gas boiler in the event of error 01. Technical information is provided for service engineers of organizations for the repair of gas equipment.

Error 01 in the electronic control board is often found when repairing gas boilers from various manufacturers of electronic heating equipment with electronic control. The first common malfunction, the lack of ignition, is the incorrect operation of the entire chain of volatile and mechanical actions, from the pilot to the main gas burner. Similar problems during the occurrence of error 01 relate to wall-mounted boilers Visman Vitopend 100, Baksi, Kiturami, Electrolux, Ariston, Immergaz, Neva Lux 8224 and other models of various manufacturers. When inspecting the gas appliance, it is necessary to make sure that all the manufacturer's recommendations for installing a gas boiler are followed: electricity, electronics, gas, chimney, air flow, correct installation of the Neva Lux boiler according to the installation diagram and the rules of the gas economy.

Repair of the gas boiler Neva Lux with error 01 information begins with checking the gas supply to the heating boiler fittings. Next, we check all RTs for operating condition, observing the contact ability of the relay. Gas modulator valve diagnostics, static and dynamic pressure check. By default, the elements of ignition, ionization are subject to inspection and maintenance. In this case, the gaps with respect to the burner section along two electrodes must be observed. Eliminate distortions and mechanical damage that interfere with the correct settings of the boiler. Diagnostics of the ignition transformer unit (coil), if there is no power to the ignition electrode.

During the repair of the Neva Lux boiler, which runs on liquefied gas, it is necessary to prepare documents for the last refueling of the gas tank (technical data of the fuel), a contract for those. maintenance of the gas boiler and call a service technician for diagnostics and repair of gas. apparatus.

Timely, constant maintenance of gas boilers Neva Lux gives uninterrupted operation of equipment, warmth and comfort in your homes. By carrying out scheduled repairs, the necessary replacement of spare parts, you extend the life of the Neva Lux boilers and make the right investment.

The Neva Lux gas water heater from a domestic manufacturer is a technically complex product. The whole cycle of work from turning on the column to heating the water is controlled by automation, which malfunctions over time. For a better understanding of the malfunction, the company's engineer placed an indicator window on the front panel, in which one or another error code is displayed during an emergency stop. Let's consider them in more detail.

ATTENTION! Maintenance operations for the repair of gas water heaters associated with the disassembly of its gas or water communications must be performed by qualified craftsmen. Self-repair can have the opposite effect, before buying a new unit.

Error E0 - lack of gas

Reason # 1. NSTurn off the gas at the descent to the column or light the gas stove. Lack of gas in the gas pipeline due to work on the pipeline. The servo motor (block with solenoid valves) is out of order.

This error cannot be eliminated on your own. You will need the help of a service worker. Contact a specialized service center for repair.

Error E1 - no flame

Ignition clicks for about a minute the burner does not ignite. The electronic control unit does not see the presence of a flame and the column goes into emergency mode.

Reason # 1. The presence of air in communications... Didle column, or after its installation, the operation of the ignition burner will occur only after air has been removed. The system should be purged by constantly turning on the column. Since the ignition lasts no more than a minute, after completion you should reopen the water tap until the ignition occurs.

Reason # 2. Lack of gas in the cylinders or the valve on the lowering to the dispenser is closed... NSOpen the shut-off valve fully. Check LPG cylinders. Replace them if necessary.

Reason number 3. There is no contact between the unit and the flame sensor... It is necessary to service the contacts coming out of the electronic unit, if necessary, clean them, tighten them for a good connection, replace the worn ones.

Reason number 4. Flame presence sensor outside the flame zone... Adjust the position of the flame detector so that its electrode is in the gas combustion zone. Make sure that the electrode does not touch other metal components. Clean the electrode from carbon deposits.

Reason number 5. The gap between the ignition plug and the igniter is broken... From constant heating and cooling, the pilot burner nozzle is deformed, which increases the gap to the spark plug. Every two years, or with a regulated maintenance, the gap should be adjusted 4 ... 5 mm.

Error E3 - breakdown of automation

The solenoid valves are triggered before the signal from the water flow sensor appears.

Reason # 1. Breakage or malfunction of solenoid valves... Call the wizard for diagnostics.

Reason # 2. Electronic control unit defective... Invite the master to the house.

Error E4 - premature inclusion

The flame detector generates a flame signal until the signal from the water flow sensor appears.

Reason # 1. You are trying to turn on the speaker using a different power source (matches).

Reason # 2. The electronic control unit is out of order.

Error E5 - no signal from the flow sensor

There is no signal coming from the water flow sensor (open circuit).

Reason # 1. Open circuit between the electronic unit and the water flow sensor... Use a tester to check the circuit and also check the sensor for an open.

Error E7 - lack of gas

The column goes out after switching on. Failed ignition attempt. Process: the igniter is ignited, then the main burner, then everything goes out and the process is repeated again.

Reasons # 1. Low gas pressure... Open the gas cock at the lowering to the column. Invite a specialist to your home to measure the gas pressure in the system and further configure the column. You should also purge and clean the gas filter.

Reason # 2. The flame ionisation sensor is not in the range of the main burner fire... Adjust the sensor. Install the electrode so that the main burner fire flushes from both sides. Carbon deposits may have formed on the sensor, which makes heating weak - clean and adjust the sensor.

Reason number 3. The mechanism in the water unit is stuck... Increased salt deposition on moving machinery leads to seizing and stopping. A stuck rod of the water unit leads to a permanent closure of the flow sensor. In this case, it is necessary to dismantle the water part and carry out preventive work: lubrication of the rod, replacement of rubber gaskets.

Error E8 - no traction

The column turns off after 2..5 minutes of work. Restarting becomes possible only after cooling down - 2..3 minutes.

Reason # 1. Lack of draft in the chimney... Clean the chimney.

Reason # 2. Soot on the heat exchanger... Increased accumulation of soot on the heat exchanger, which prevents the passage of carbon monoxide into the chimney. To fix the problem, the column should be serviced.

Reason number 3. The traction sensor is faulty... The traction sensor works for rupture. Over time, the sensor becomes very sensitive to vibrations and can turn off the column during heating. Therefore, with this error, the sensor will be checked for operability.

Error 99 - short circuit

Numbers 99 blink on the display for a while, then the column turns off with an error message LO.

Reason # 1. Closed the water temperature sensor(makes sure that the heat exchanger does not overheat). The error can be eliminated only by replacing the sensor and its wires.

Error H1 - insufficient heating

The column does not heat the water to the specified temperature.

Reason # 1. High temperature set at high head. The column cannot cope with heating the amount of water that passes through the column. Reduce head.

Reason # 2 ... Burner clogged with dust. If you notice that the gas is burning orange, and the flame is sluggish and elongated, then it's time to clean the burner. If you neglect cleaning, then this error will appear constantly. The efficiency of the column will be halved. A lot of soot will appear.
