Troubleshooting

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

Perhaps in your expansion tank pressure is lower than expected. This is when error 04 is possible.

Six months ago I installed a double-circuit boiler Neva Lux 8230. Recently I encountered the following problem. When I needed hot water, I opened the tap as usual. At first it went warm, and then cold again. At that moment, error 02 appeared on it. I tried to reset it with the “reset” key, but after that the heating turned on. After this, hot water was needed again in the evening. I opened 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 domestic hot water occurs, a sound similar to air being sucked in is heard inside. At the same time, instability of the pressure gauge readings can be observed (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 18l). After this, the pressure rises sharply to 5 bar. A shutdown occurs and the water temperature drops to 23C. And error 02 is displayed. The instructions say that I have air in the heating system, but I am working with hot water. What connection? Maybe my three-way valve is broken? Or is my filter in the heating system itself clogged?

Error 02 - the coolant is overheating. The fan may be broken or the sensor may be damaged.

My Neva Lux 7023 boiler stops about 2 times a month due to error 07. Rebooting 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. You may have a heat exchanger with inside all covered in scale, and because of it there is poor circulation in the system. Has it started to make some unusual noise? But regarding E5, here you need to pay attention to the pressure switch or fan. You need to look at both. In a good way, this problem should be solved by a specialist. Just in case, check to see if your chimney is frozen.

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. So is there a relay on the board? A couple of years ago I encountered something similar. But then a friend helped me out by giving me some 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 was flowing. Is the same relay responsible for this? But now the error was 01.

In order for the relay to work longer, you need to configure it more carefully gas valve and heating power, 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 flows. 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 estimating gas pressure. And so, most likely you little house and you did not configure 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 due to error 04. They began to recharge it, 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. Does it mean you can't use it?

The pressure switch needs to be checked. A small air vent tube could be clogged in the chimney.

My wall-mounted boiler Neva Lux 7023 (Baltgaz) has a problem with the hot water supply. Everything is fine with the heating, but as soon as I start drawing water, error E2 appears. The water does not heat up. If you turn off the water, it continues to heat the apartment completely 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. At DHW operation the burner starts working and burns for 2 seconds. Then the thermometer shows a temperature of 95C, the device immediately turns off and an error occurs. The water runs warm as long as the burner is on. What could have broken?

Try checking the DHW temperature sensor, this may be the issue. Although, in theory, error E2 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 mode heating system for hot water supply. Although, sometimes, for reasons unknown to me, 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 intact 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 technician who came to me suggested that the problem was in the flow sensor. He did not see a signal coming to him. Need a new one. But I did something to make the device work. It didn't work for a day, and then I needed to turn it on. But it doesn't start. The indicator blinks, all possible symbols are highlighted. Rebooting didn't help. I disconnected the power - that didn't 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 responsible for driving the three-way valve. Then re-fasten them. This should solve your problem.

I just can’t fix the Baltgaz Neva boiler. Error 03 constantly appears, the fan does not work when igniting. If you blow on the pressure switch tube, it starts to spin. The device does not want to turn off on its own; you have to do it manually. What should I do?

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

What does error 01 mean, how to troubleshoot problems when repairing Neva Lux?

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

So, with error 01, the flame does not ignite in the combustion chamber, or ignition begins, but is unsuccessful - the Neva boiler does not work. Briefly, in this case, there may be one or several causes of error 01 at the same time. Let's consider all the causes of the emergency and give the full scope of recommendations for repairing the Neva Lux gas boiler when error 01 occurs. Technical information is provided for service engineers of gas equipment repair organizations.

Error 01 in the electronic control board is often found when repairing gas boilers from various manufacturers of electrically controlled heating equipment with electronic control. The first common malfunction, lack of ignition, is the incorrect operation of the entire chain of energy-dependent and mechanical actions, starting from the pilot and ending with the main one. gas burner. Similar problems during the occurrence of error 01 apply to wall-mounted boilers Visman Vitopend 100, Baksi, Kiturami, Electrolux, Ariston, Immergaz, Neva Lux 8224 and other models from various manufacturers. During an external inspection of the gas appliance, you must 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 wiring diagram and gas regulations.

Repair of the Neva Lux gas boiler with error 01 information begins with checking the gas supply to the heating boiler fittings. Next, we check all RTs for working condition, observing the contact ability of the relay. Diagnostics of the gas modulator valve, checking static and dynamic pressure. By default, the ignition and ionization elements are subject to inspection and maintenance. In this case, the gaps should be maintained relative to the burner section along the two electrodes. Eliminate distortions and mechanical damage that interfere correct settings 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 operating on liquefied gas, it is necessary to prepare documents for the last filling of the gas tank (technical data of the fuel), a technical agreement. gas boiler maintenance and call a specialist service department for gas diagnostics and repairs. apparatus.

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

The Neva Lux geyser from a domestic manufacturer is a technically complex product. The entire operating cycle, from turning on the water heater to heating the water, is controlled by automation, which malfunctions over time. To better understand the malfunction, the company engineer placed an indicator window on the front panel, in which one or another error code is displayed during an emergency stop. Let's take a closer look at them.

ATTENTION! Maintenance operations and repair of geysers associated with dismantling its gas or water communications must be performed by qualified craftsmen. DIY repair can give the opposite effect, in a raft before purchasing a new device.

Error E0 - lack of gas

Reason #1. PThe gas is closed on the descent to the column or ignite gas stove. Lack of gas in the gas pipeline due to work on the main line. The servomotor (unit with solenoid valves) has failed.

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

Error E1 - no flame

The 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. Presence of air in communications. Da simple column, or after its installation, the pilot burner will operate only after air has been removed. The system should be purged by constantly turning on the column. Since ignition lasts no more than a minute, after completion you should reopen the water tap until ignition occurs.

Reason #2. Lack of gas in the cylinders or the tap on the descent to the column is closed. POpen the shut-off valve completely. Check gas cylinders with liquefied gas. Replace them if necessary.

Reason #3. There is no contact between the block and the flame sensor. The contacts coming out of the electronic unit should be serviced, if necessary, cleaned and tightened to good connection, worn out, replace.

Reason #4. Flame sensor outside the flame zone. Adjust the position of the flame sensor 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 #5. The gap between the spark plug and the igniter is broken. Due to constant heating and cooling, the ignition burner nozzle is deformed, which increases the gap to the spark plug. Once every two years, or during regulated maintenance, the gap should be adjusted to 4...5 mm.

Error E3 - automation failure

Trigger solenoid valves occurs before the signal from the water flow sensor appears.

Reason #1. Broken or malfunctioning solenoid valves. Call a technician for diagnostics.

Reason #2. The electronic control unit is faulty. Invite a handyman to your home.

Error E4 - premature switching on

The flame presence sensor gives a signal about the presence of a flame before 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 has failed.

Error E5 - no signal from the flow sensor

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

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

Error E7 - lack of gas

The speaker goes out after switching on. Unsuccessful ignition attempt. Process: the igniter lights up, then the main burner, then everything goes out and the process repeats again.

Reason #1. Low gas pressure. Open the gas valve on the downstream side of the column. Invite a specialist to your home to measure the gas pressure in the system and further configure the column. You should also blow out and clean the gas filter.

Reason #2. The flame ionization sensor is not in the fire zone of the main burner. Adjust the sensor. Install the electrode so that the fire of the main burner washes on both sides. It is possible that carbon deposits have formed on the sensor, which makes heating weak - clean and adjust the sensor.

Reason #3. The mechanism in the water unit is stuck. Increased deposition of salts on moving mechanisms leads to jamming and stopping. A stuck rod of the water unit leads to a permanent short circuit of the flow sensor. In this case, you should dismantle the water part and carry out preventive work: lubricate the rod, replace rubber gaskets.

Error E8 - no traction

The column turns off after 2..5 minutes of operation. 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 resolve the problem, the column must be serviced.

Reason #3. The traction sensor is faulty. The traction sensor works to break. Over time, the sensor becomes very sensitive to vibrations and may turn off the column during heating. Therefore, if this error occurs, the sensor will be checked for functionality.

Error 99 - short circuit

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

Reason #1. Water temperature sensor is shorted(make sure that the heat exchanger does not overheat). The error can only be eliminated by replacing the sensor and its wires.

Error H1 - insufficient heating

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

Reason #1. Given heat under high pressure. The column cannot heat the amount of water that passes through the column. Reduce pressure.

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