Repair of gearbox from OGV Astra. Why doesn't the Astra gas water heater light up? What tools are needed?

Geyser Astra has long been popular with Russian consumers. These inexpensive and functional devices, which heat water in Russian homes, effectively convert inexpensive energy resources into heat. Preferring a gas water heater to a boiler, homeowners rely on the efficiency of blue fuel, so it is not surprising that Astra, simple in design and affordable, is a success.

About the company "Heat Exchanger"

Manufacturer of gas water heaters "Astra" - Russian company"Heat exchanger". This powerful enterprise is located in Nizhny Novgorod, and has been engaged in high-tech production for 60 years. More than 50% of its products are in the aviation industry, and water heaters make up only a fifth of the products produced by this giant. The dispensers produced by the plant operate only on natural gas. Combustion products are removed through a chimney. The company previously produced KG water heaters, today they are obsolete, and the plant offers Russian consumers more modern versions– economical, high efficiency, durable and safe.

Why are geysers popular?

It’s good when hot water flows from the tap “by itself” in an apartment, but some residents of apartment buildings can only dream of this. The deplorable state of housing and communal services networks forces Russians to independently solve the problem of hot water supply, choosing between a boiler and a water heater. If gas is not supplied to the house, there is no question - you have to buy a boiler; if blue fuel is available, a gas appliance is a more profitable option. The offered models differ in power and performance. The maximum value is 20 kW. By consuming gas moderately, they save their owners money. The average price is 9,000 rubles. Chimney diameter – up to 12 cm.

What are the benefits of Astra Group of Companies?

The Nizhny Novgorod enterprise offers not one or two modifications of gas-powered water heaters, but a whole the lineup, which presents speakers of different power and performance. All gas heaters can be divided into two groups:

• Flow-through. They heat the water constantly. They are more compact and can be installed in tight spaces.
• Cumulative. Heat a certain volume of water - 50-500 liters. This option is selected taking into account the needs of the family.

Advantages of Astra products:

• Made in Russia. Therefore, they are inexpensive and can be easily repaired. If it breaks, you can always find a suitable spare part and fix it.
• The heating container has a heat-insulating layer, so the heated water does not cool down for a long time - resources are saved.
• Simple design - you can easily understand everything. Reliable device - tested by consumers. It's easy to figure out how to use the device.
• There is nothing superfluous, no “functionality”, it just heats the water. This has a positive effect on the price.
• Good productivity - up to 12 liters per minute. This is enough for two water intake points.
• Safety. The machine turns off the device when there is no draft, when the water supply stops and when there is no flame.

But the system quickly increases the temperature. Cons: limited pressure parameters that the valve can withstand. There are burner breakdowns.

Which models are the most purchased?

Consumers are happy to express their emotions to domestic technology, mentally accustomed to scolding everything that is done in Russia. When discussing Nizhny Novgorod gas water heaters, you need to be objective and take into account the realities of domestic consumption. Any equipment is prone to wear and tear and cannot for a long time operate at full capacity: breakdowns and malfunctions are common for equipment dealing with different types resources. The GC models received the greatest recognition among consumers:

• Astra 8910-10 has become the number 1 choice for its extreme simplicity and low cost. Estimated cost 5,000 rubles.
• JSD20-10A. Consumers are attracted by electronic ignition and the absence of an ever-burning wick.

If your water heater breaks down

Before you begin repairing gas water heaters, regardless of the type of breakdown, you need to shut off the gas supply. The device itself does not need to be removed - all structural parts are accessible without dismantling. But the “facade” - the front cover of the heater, needs to be removed by unscrewing the side bolts with a screwdriver. First you need to inspect the heat exchanger - it is located behind the electrode, fixed with four bolts. It is not recommended to unscrew the heat exchanger.

When repairing device components, the main thing is not to touch the fitting - this element is needed to measure water pressure. If you accidentally damage the fitting, you will need to replace the head. The main malfunctions of gas water heaters:

• Contacts are dirty. Contacts that have become unusable must be replaced with new ones.
• The heat exchanger is damaged. Correcting the situation is replacement.

If the column does not light up

The most common problem that happens with a gas water heater is that the heater does not light up. The cause of the problem may be a lack of traction. Before turning on the column, you need to check the draft in the ventilation hole - light a match and bring it to the chimney outlet. If everything is in order, then the flame seems to be drawn into the hole - there is draft, and you can turn on the device. If the flame does not stop, the chimney needs to be cleaned. You can do this yourself, but if you lack the skills, it is better to entrust it to a specialist.

Another common malfunction that occurs with gas-powered water heaters is extinguishing after ignition. If the wick goes out, you need to adjust the cold water supply.

Typical breakdowns

It happens that in the devices in question the hydraulic unit breaks down. It is easy to dismantle, but difficult to put back in place. After disconnecting the hydraulic group, you must immediately check the valves - they must be securely fastened. If the valves move, or the tightness of the connection is compromised, they must be replaced immediately. When purchasing elements of a hydraulic unit, it is important to know the modification of the hydraulic unit.

Also, the solenoid valve may break down in the main body. This is a small problem, but if it is not addressed in a timely manner, the consequences can be very serious. The valve may deteriorate due to clogging with combustion products - you need to urgently clean it of soot, otherwise there is a risk of explosion.

How much do spare parts cost?

The advantage of Astra heaters is the availability of spare parts. Since the devices are made in Russia, there are no problems with spare parts. The main thing is to order and pay. How much do spare parts cost? Approximately:

• price of a gas unit – 1500 rubles;
• water price - 1600 rubles;
• the cost of a magnetic plug is 200 rubles;
• repair kit for the water part - 150 rubles.

What tools are needed?

To connect, configure, repair or service the device, a screwdriver alone is not enough; you need a set of tools:

• Adjustable wrench – 2 types.
• Pipe wrench.
• Gaskets – paronite and rubber.
• Screwdrivers – Phillips and flat head.
• 1-2 inch rubber hose and metal clamp.
• Special composition - remove scale.
• Bucket - drain water.

The Astra speaker sold quite briskly in the late nineties and early two thousand. A gas water heater was produced in Nizhny Novgorod

The speaker is quite powerful. Gives boiling water easily. I won’t rip off the description from the passport. I would like to tell you about the problems that I most often encounter when repairing these water heaters.

The column, with minor modifications, borrowed the water block from the notorious so-called “Stalinist” column KGI-56. The size of the water block membrane is the same (the membranes are interchangeable). The bottom of the water block is different. In Astra, the water pipes to the block are connected from the side, while in KGI-56 it is from the bottom or from the rear wall. The failures in the block are the same - leaks from the rod seal, deformation or rupture of the membrane (the main burner does not ignite). It is not the design of the water block itself that has gone downhill, but the material from which it is made. On the Astra HSV it is made of aluminum alloy, which is much worse than brass or bronze. Over time, especially if there have been leaks in the water block, silumin is very strongly oxidized and it becomes impossible to disassemble the block to replace the membrane. It’s good if you can unscrew the tubes from the block to replace the entire block. By the way, the price of a block for this rarity is also steep - about 1000 rubles.

The gas block with two levers is the same as that of the KGI, but modified. This geyser has a safety automatic, consisting of a thermocouple and a solenoid valve. There are both failures of thermocouples and valves. Gas is supplied to the column igniter from the gas block, and the air for combustion of the igniter is taken from the top of the column. This was not done by accident. If there is no draft in the chimney, then carbon monoxide enters the room at the top of the column. The air intake for the igniter is also located there. If there is no draft, the oxygen required for combustion is no longer supplied to the igniter, and it goes out. Accordingly, the thermocouple cools down and closes gas valve. This is how protection against lack of traction is implemented in this column. I have never seen this on any other mass-installed speakers.

Another “bottleneck” point of this column is the tubes going to the heat exchanger. The tubes are connected to the heat exchanger using union nuts. Gaskets gradually shrink due to temperature changes and begin to leak. Since the tubes are copper and the union nuts are steel, this connection boils very quickly so that nothing can be used to unscrew it. We also came across tubes that began to leak over time (through corrosion).

Problems with heat exchangers are rare. The walls of the combustion chamber are made of heat-insulating material.

Let's summarize. A quite common dispenser with poor maintainability of the water part. Because of this, many craftsmen simply do not like to repair them. The gas part and heat exchanger usually do not cause problems.

Why should you choose Astra geysers: reviews

Among the main advantages of the equipment described in the article, consumers highlight:

• lack of unnecessary functionality;
• reliability;
• the ability to easily configure the operation of the equipment;
• high productivity;
• simple device;
• ease of use.

The equipment, according to consumers, is repairable. All spare parts can be found in service workshops. And the column itself is quite cheap. Buyers especially like large combustion chambers, so the power of some models reaches 20 kW.

The traction control of the 8910 model is carried out independently. Thermostat in this option located below. The smoke exhaust path is quite wide, but the column regulator is located under the central fitting. The frame of the structure, according to property owners who purchased such equipment for themselves, is very durable, so it can withstand any load.

The power supply has a protection system. Using special screws, you can easily adjust the fitting. The Astra geyser, the operating instructions for which is supplied, has, according to consumers, economical fuel consumption. The design has a high-quality pressure regulator. Traction can be checked very simply. Removal of combustion products occurs quickly. In terms of safety, the speaker outperforms other models.

Repair of Astra brand geyser

Repair of the Astra geyser begins with shutting off the gas. The column does not need to be removed. The front part can be dismantled using a screwdriver, but first you need to unscrew the bolts located on the sides. The first thing you need to check is the economizer; it is located behind the electrode. Removing the latter will be quite difficult. It is fixed with 4 bolts. You should not touch the heat exchanger.

When you repair individual components, it is important not to touch the fitting; it is used to measure pressure. If this part is damaged, the head will have to be replaced. In order to remove the economizer, you only need to unscrew the two side bolts. The consumer may well carry out the repairs with his own hands. The Astra geyser has contacts in its design that often become dirty. If they become unusable, they need to be replaced. If the economizer does not work after replacement, then it will also have to be changed. These faults are among the main ones for Astra speakers.

If you are faced with a problem when the Astra gas water heater does not light up, this may indicate a lack of draft in the ventilation passage. You can check the traction very simply. The gas water heater is turned off, and a burning match should be brought to the chimney outlet. If the flame is carried into the chimney, then everything is in order - you can connect the column. Otherwise, the chimney should be cleaned. However, it is better to entrust this matter to a special master.

The Astra geyser, the malfunctions of which you should consider when operating this equipment, sometimes goes out immediately after ignition. In this case, you should adjust the supply of cold water to the column. You should not try to dilute hot and cold water, this may cause the flame to go out.

Spare parts for Astra brand gas water heater

If you purchased an Astra 8910 geyser, you may need spare parts for it during operation. You need to know what their cost is. For example, a water unit will cost 1,600 rubles. The gas part costs 1,500 rubles. The magnetic plug has more low price- 205 rub. The membrane costs 25 rubles. The repair kit for the water part costs 155 rubles, and the adjustment unit costs 55 rubles.

Conclusion

If you still don’t know whether it’s worth purchasing an Astra brand geyser, then you should consider its features in more detail. For example, the copper heat exchanger of all models has increased wall thickness. This ensures good heat transfer from heated gases to water, which allows for savings. For more convenient operation, the manufacturer has equipped the design with a display with which you can determine the temperature of the heated water.
