Electrolux geyser troubleshooting: diagnostics of popular breakdowns and troubleshooting methods

The internal structure of the column "Oasis"

Before you start troubleshooting the Oasis geyser and choosing a way to eliminate them, you need to clearly understand what type the device belongs to, know the device, the principle of its operation.

The layout of the nodes of the Oasis geyser is typical for most models of Chinese-made flow columns

Above in the diagram, the device of a typical gas water heater is considered, which is also typical for the Oasis columns. Let us further consider how the most common type of brand chimney flow model with automatic ignition works.

When the tap is opened, water is supplied through the inlet pipe to the water-gas unit, which includes ignition and gas supply. As soon as it ignites, a signal is sent from the flame sensor to the electronic unit to stop sparking.

Further, the water passes through the coil, rigidly fixed on the heat exchanger, which is heated by the burning gas. The coil gives off heat to the outgoing running water.

When the tap is closed, the water-gas unit turns off the gas supply. The burning stops and the column goes into standby mode for the opening of the water tap.

An important condition for the normal and safe operation of the column is the removal of combustion products through the ventilation chimney. If the hood is missing or insufficient, the draft sensor is activated and the column turns off.

An overheating sensor is responsible for the timely shutdown of the column when the limit temperature is reached. It is an important element of the column, providing protection against overheating.

Maintaining the required temperature regime is an equally important condition for fire safety and a long service life of the column. Overheating adversely affects the condition of all elements, primarily the heat exchanger, which leads to their premature failure.

Which is better to buy a geyser Electrolux: let's evaluate the important parameters

You should not stop at the popularity of models either. Our experts encourage the user to accurately determine the main technical characteristics that meet your expectations

So, what are the things you should pay attention to so as not to become a victim of an unwanted purchase?

Design and power - how they will change for rooms of different sizes

For houses with large dimensions, different models of Electrolux equipment are suitable - the main thing is that they have high power (from 28 kW) and be able to process up to several water intake points. This is welcomed in country houses and cottages. This does not have to be limited to a discreet design. If there is a financial opportunity, you can purchase a custom model.

Pay attention to the need for regular cleaning of gas column nozzles. Devices with maximum power clog especially quickly.

If you are making a purchase of water heaters with a proposed installation in a small kitchen, then the best indicator would be power up to 24 kW. This is quite enough to heat water in a small "Khrushchev".

Which control and ignition method is best for a gas water heater

If you happened to see a gas column with friends or relatives, you were probably given all sorts of advice on how to manage it. It is up to you to choose how it is more convenient to control the speaker - using flat touch buttons or using the turn of knobs and toggle switches.

When installing gas water heaters at home, remember to use three-phase wiring.

Regarding electronic control geysers Electrolux we can say the following: they do not tolerate contact with moisture. You will not be able to approach the appliance and increase the temperature immediately after washing the dishes until you dry your hands. But mechanical handles work even in damp conditions - but is it worth exposing them to this once again?

The type of ignition of gas water heaters is conditionally divided into three types:

• start with a piezo;
• electric ignition (using batteries);
• from open flame (matches, lighter).

Each of the methods of turning on the device is good in its own way, but it can also bring some inconvenience. For example, it will not work to light a column without electricity if the element is a piezo component; after the batteries are discharged, you will also not be able to cope with the start of the equipment. The only alternative left is to use matches to light the fire. Again, they should always be in the house.

Geysers are suitable for any type of chimney, the main thing is that it has good throughput and no blockage in the channel.

The safety of the gas column

What is this property? Almost every second buyer asks such a question. The safety of the device lies precisely in the presence of additional protective features:

• thermostat to prevent overheating of the device;
• protective shutdown in case of pressure drop of gas or water;
• a check valve that relieves pressure if it goes beyond the norm and threatens to explode;
• protective shutdown (built-in RCD) is useful in case there is a power failure in the mains.

It is a mistake to think that the geyser only works on "blue fuel". It also needs electricity to function properly.

Safety system

All systems and the Electrolux GWH 265 ERN NanoPlus heat exchanger are manufactured in accordance with the most stringent modern quality standards that are currently applied in Europe and Russia. Therefore, the presented equipment is completely safe to use. The design provides for several systems that are responsible for this process.

A multi-level security system consists of several elements. These include a draft sensor, which, if necessary, transmits a signal to turn off the equipment. Also included is a safety thermostat. It prevents the system from overheating. The hydraulic safety valve helps to protect the equipment from improper water pressure in the system.

Also, the safety system of the geyser includes a flame ionization control device. Modern devices carefully record all column operation data. In the event of various malfunctions, they turn off the equipment.

In order for the operation of the gas column to comply with modern safety rules and standards, the installation may only be carried out by qualified personnel. To do this, after purchasing the presented equipment, you need to contact a specialized organization. It must have an appropriate license from the Gosgortekhnadzor of the Russian Federation.

During installation, an employee of an authorized company must adhere to the rules clearly stated in the Electrolux GWH 265 ERN NanoPlus instructions. Only in this case the company provides a guarantee for its products, and the life of the equipment will be as long as possible. Installing gas equipment yourself is unsafe.

Commissioning must also be carried out by an employee of a specialized company. You need to insert the batteries into the appropriate compartment. Next, turn the power adjustment knob smoothly. The column will be in a standby state until the hot water tap is opened. Sometimes it is not possible to turn on the equipment the first time.The same situation happens after a long stay of equipment in inactivity. There may be air in the gas pipe. It is necessary to repeat the ignition attempts several times. The air at this time will gradually come out of the pipe.

Equipment checks and maintenance must be carried out annually. The procedure includes a number of procedures. They are prescribed by law. It is not recommended to ignore such actions. This work is carried out exclusively by a trained specialist. Doing maintenance yourself is strictly prohibited.

Varieties of geysers

These devices are divided according to the type of ignition into:

• electronic;
• manual;
• with piezo ignition.

Manual geysers are the last century. To use them, it is necessary to supply gas to the column and light the igniter with the help of matches. To turn on the main burner, it is necessary to give an appropriate control signal.

Now there are more practical geysers that meet the requirements of modern people who are used to the fact that automation does all the work for them. The electronic ignition system works as follows. Again, it all starts with the opening of hot water. The system detects a drop in water pressure and gives a signal for gas supply and spark formation. After these actions, the fuse lights up, and then the process is the same as in manual burners. The main burner will come into play, and the heated water will flow to the turned on tap. The burners also turn off automatically - after the valve is closed and the pressure is restored.

Geysers with piezo ignition use the so-called piezoelectric effect to work, as can be seen from their name.When the device is turned on, a button is pressed, which converts the mechanical action into an electrical discharge. As a result of the discharge, the igniter will light up, and then the second burner. After the hot water is turned off, the main part goes out of work, but the igniter continues to burn. Therefore, the next time you turn on the hot tap, everything will work automatically.

Incorrect water heating

The cause of this problem may be the wrong choice of the power of the installation. To do this, when buying, you need to make sure that the Bosch gas water heater or another company has the necessary characteristics for your home. In addition, there may be a blockage of the device. This is confirmed by the presence of soot and the uncharacteristic color of the flame. With insufficient heating, you can try to adjust the energy supply. This is done with a special crane.

There is also the opposite situation - the water is too hot. Here, the Bosch gas column does not require repair, since this is not considered a malfunction. This is because the temperature of the water in the water supply is warmer in the summer, and the pressure drops. Many geysers are not designed for this mode. The characteristics of gas water heaters include the optimal water pressure at which the normal operation of the unit is ensured. The solution to this problem is as follows: it is necessary to reduce the supply of energy.

Sources of the accident

There are several reasons for the failure of the burner, the main ones are the following factors:

1. Lack of traction.

For any model, be it the Neva, Oasis or Vector, the flame goes out or does not light up due to the fact that the chimney is often clogged with dust, dirt and foreign objects.In modern equipment, in this case, a protective valve is activated, which automatically shuts off the fuel supply to the gas column. This is because the products of combustion are not discharged in full and in accordance with the technical requirements.

To verify the malfunction, you need to check the traction. To do this, open a window and bring a lighted match or a sheet of paper to the pipe. If the chimney is clogged, the wind will not be felt, so the geyser does not light up. The cleaning of the combustion waste disposal system is carried out by specialists

It is important not to miss this moment, as the exhaust gas enters the room, which can lead to serious consequences.

An ingenious way to almost NOT PAY for electricity! A clever meter that saves electricity Pays for itself in 2 months!

Sometimes the automation works when the hood is turned on, located nearby, the flame goes out or does not appear. If the device has a large power, it interferes with the removal of waste, so you should never install two units in one place, especially in small rooms.

2. Malfunction of sensors.

If the igniter flame goes out, it is necessary to inspect the device that controls the exhaust of gases. To do this, disconnect the wires and check the resistance using a special device. The indicator must be indicated in the passport, if it does not reach the optimal value, the sensor will have to be replaced. The burner goes out when the thermocouple breaks. In this case, the gas column does not ignite due to low voltage, the optimal parameter of which is 10 mV.

3. Discharged batteries.

The main function of the batteries is to keep the valve open during operation.The service life of the elements is no more than a year, therefore, manufacturers of such gas units as the Neva recommend changing batteries on time. In addition, the reason that the burner does not ignite may be a malfunction of the piezoelectric element or the power cable. It is necessary to disconnect the wires and check them for internal and external breaks. If there is still no spark, the column does not turn on, then the source of the problem is different.

4. Blockage of the inside.

If dirt and soot get into the gas supply tunnel from the fittings to the burner, the flame goes out or does not ignite. The injectors need to be cleaned. If the fuel pressure is not adjusted, a characteristic whistle will be heard, flame separation appears, then it disappears. Also, a burner of the wrong diameter can create such a malfunction. In this case, you need to correct the gas supply or replace the elements. When airing, the gas column ignites, but immediately goes out. To eliminate the defect, you need to unscrew the nut on the fitting and bleed the air, then return the mount to its place, fix it and check if the burner goes out.

5. Deformation of elements.

If the water is too hard, scale appears in the pipes, which gradually clogs the filters, so the gas unit goes out or does not turn on. The grate is taken out, thoroughly cleaned. If it has been damaged by deposits, it is better to replace it.

The membrane of the water supply unit often breaks, so the column does not turn on. To determine its condition, remove the top cover of the case. The plate should not be in cracks and gaps, has the correct shape, smooth and even. In case of the slightest deformation, it will have to be replaced.It is better to choose a part made of a durable and elastic material that is resistant to temperature fluctuations and the influence of scale. Install the membrane carefully, crimping the fasteners around the perimeter.

6. Water pressure.

As in the draft situation, the automation blocks the gas supply; if the supply is poor, the burner immediately goes out. It is worth contacting the utilities to find out the reasons, turn off the unit until then. You can use the column only if the water pressure is normal. In private homes, the pressure is increased using a compact station and a regulator. If the column turns on and works normally, and the water is still cold, the device may not have enough power, the parameters are noted in the passport.

Water heater repair Ariston

A common malfunction of this model, however, as well as similar ones, is the absence of a flame due to the failure of the water membrane. If the rubber is damaged, then this element will not be able to press the gas supply rod.

In this case, the part should be removed and a new membrane purchased from a specialized store, and then replaced. To remove the damaged membrane, first disconnect the water pipelines from the column, remove the heat exchanger and the cover of the water unit, under which the membrane is located.

In case of violation of the permissible draft in the chimney, a signal will be sent to the control panel from the corresponding sensor. In this case, it will not be possible to start the water heater until the malfunction is corrected.The flame of the burner will ignite, but after a few seconds the fire will die out. Usually, the draft is checked with a lit candle or match.

The principle of operation of the sensor

The gas boiler works by burning blue fuel. Naturally, in this case, combustion products are released. If they get into the room, then this is fraught with severe poisoning of all residents of the house, up to and including death. Therefore, the design of the column provides for connection to the chimney, through which all harmful substances are removed to the street.

Naturally, for high-quality removal, the ventilation shaft must have impeccable draft. But it happens that some kind of violation occurs - for example, the chimney can become clogged with debris or soot. If in such a situation the boiler stubbornly continues to burn fuel, then the combustion products will inevitably go into the house.

To prevent this, an element such as a chimney draft sensor is included in the design of the gas boiler. It is located in the place that is located between the ventilation duct and the equipment case. The type of sensor depends on the type of boiler:

• in a boiler with an open combustion chamber, the protective sensor is a metal plate to which a contact is connected. This plate is the indicator that monitors the temperature increase. The fact is that normally escaping gases are usually heated to 120-140 degrees. If the outflow is disturbed, and they begin to accumulate, then this value increases. The metal from which the plate is made reacts to such a situation and expands. The contact attached to the element is displaced and closes the valve responsible for the gas supply. Thus, the combustion process stops, and at the same time, the entry of a new portion of harmful substances is prevented,
• in a boiler with a closed combustion chamber, the products are removed through a coaxial channel, while a fan is used. The sensor in this case is a pneumatic relay with a membrane. It reacts not to temperature, but to the flow rate. While it is within the acceptable range, the membrane is bent, and the contacts are in the closed position. When the flow rate becomes weaker than necessary, the membrane straightens, the contacts open, and this leads to the blocking of the gas supply valve.

As you can see, if the draft sensor is triggered, turning off the gas column, this means some kind of malfunction in the equipment. For example, it could be:

• initially poor quality traction. This is the first and main reason why the sensor can work. As a rule, this phenomenon is associated with improper installation of the exhaust structure. If the products of combustion are poorly drawn out, then this is a danger to all living things in the house,
• reverse thrust. This phenomenon occurs when an air lock forms in the chimney. Gases, which normally should move to the very top of the pipe and then go outside, cannot overcome this obstacle and return back, filling the room with themselves. The effect of reverse draft can occur if the thermal insulation of the chimney is made very poorly. The temperature difference and leads to the formation of air pockets,
• chimney blockage. It may seem to inexperienced owners that the pipe leading to the roof simply cannot be clogged with anything. In fact, there are many factors that lead to clogging. The first one is birds. They can make nests on the pipe, which then fall down. Yes, and the birds themselves often manage to get stuck in the chimney, and then die there.In addition to birds, one should also take into account the possibility of getting, for example, leaves, as well as the deposition of soot on the inner walls of the pipe. If the chimney is clogged, the draft intensity becomes too low, and there is only one way out - cleaning,
• strong wind. If the pipe is not properly positioned, gusts can enter it and blow out the burner. Naturally, in such cases, the sensor shuts off the fuel supply. To avoid such a danger, it is necessary to purchase and install a stabilizer.

Peculiarities

Electrolux water heaters are equipment that can heat water and maintain its temperature for a long time and without interruption. The design can perform its functions in any conditions. The technical features of the devices provide speakers with reliability and safety. Water heating equipment of this company is able to work not only on one or several points of water intake. It has found wide use both in the domestic sphere and in offices.

Each model has its own characteristics and performance, so when choosing a product, the buyer should be guided by personal taste and needs. Consider the main characteristics of the Electrolux speakers.

• Power. The manufacturer sells a product that can be of three types and differ from each other in performance and power: low-power equipment - 17-19 kilowatts; medium power - 20-24 kilowatts; powerful - 25-31 kilowatts. Each presented option can work for a certain number of water intake points.
• Control method. The manual control method has long been outdated, it has been replaced by a new, more advanced one.Modern models of Electrolux geysers have a built-in burner with independent power simulation. Thanks to this, the equipment is able to control the temperature regime, as well as maintain it at the required level, even with insufficient pressure. The automatic system independently selects and regulates the temperature.
• Ignition type. The manufacturer sells several models of gas water heaters: with manual, automatic and piezo ignition. The equipment of the first option is now practically not found. Automatic ignition is the most convenient option to use.
• Safety. Electrolux speakers are equipped with three-level and four-level security. When unexpected interruptions occur in the system, for example, a pressure change, a gas or water leak occurs, the device turns itself off.

Electrolux water heating equipment is characterized not only by advanced technical parameters, but also by an attractive design. Everyone will be able to choose for themselves the ideal option that fits perfectly into the interior. Geysers are presented both in a minimalist style and with an improved external panel. Devices on the front panel of which you can change pictures that fit the style of the room are very popular.

Main causes of malfunctions

The device may not work for various reasons. For example, the geyser does not light up. You can immediately contact a specialist. However, with many breakdowns you can handle yourself.

If the device is under warranty, it is better to contact the master. It will determine why the device is not working.Geysers of different manufacturers are known. Water heaters Neva, Vector, Orion have automatic ignition. With proper use, they last a long time. The gas column Oasis has a semi-automatic ignition mode.

Geyser Astra has manual ignition. If it does not light up, you need to inspect the heat exchanger - maybe dirt has accumulated there.

The Oasis geyser lights up and goes out for the same reasons as many other appliances: a chimney is clogged, poor draft, a radiator is clogged, water or gas pressure has dropped. Sometimes the cause may be a strong gust of wind, a broken sensor, a mixture of hot and cold water, or a damaged membrane.

External fault factors

What to do if the gas column does not light up? Failures in the operation of the gas column can be caused by circumstances beyond its control. Let's consider them in order:

Gas supply

There is nothing special to talk about here, and everything is clear: if the gas is turned off, the water heater will not work.

Just do not rush to immediately blame the gas workers for everything.

If there is a filter in the system, first make sure it is not clogged.

Water pipes

Here are some surprises that the water supply system can present:

Pipe connection failed

It is a likely reason, especially if an amateur takes up the installation of the column. If a newly installed water heater refuses to work, check the connection diagram again.

Insufficient pressure

Some of the gas water heaters are equipped with an ignition system, which is powered by a stream of water - it rotates an impeller connected to a piezoelectric element.

With a weak pressure, of course, such a system will be inoperative.

The opening of the gas valve is also carried out by water pressure - through the membrane, which was mentioned above. If the water is barely flowing, the valve will remain tightly closed.

Most often, pressure problems occur in rural areas. When buying a column, their residents should definitely specify at what minimum pressure it can work.

However, even in urban conditions, the pressure in the pipe may turn out to be scanty. The reason is the clogging of the mesh filter installed in front of the column. To test this hypothesis, open a cold water faucet on the mixer. If the pressure here is normal, then the problem is really local in nature - you need to check the strainer or heat exchanger (more on that below).

The inlet water temperature has risen

Some users, out of inexperience, forget to take into account the fact that the water in the water supply becomes warmer with the beginning of the spring-summer season. If the speaker remains set to winter mode, it will constantly turn off due to overheating.

Smoke exhaust system

In the absence of draft in the chimney, protective automation, despite all your exhortations, will not allow you to use the column.

For example, if the chimney is clogged, the gas water heater will not ignite.

External causes that may worsen the outflow of combustion products include the following:

1. Clogged chimney: debris or birds can get into the chimney. In addition, over time, it becomes overgrown with soot, so it needs periodic cleaning.
2. Installation of large objects above the chimney head: in most cases, such an object becomes a television satellite dish. It prevents the free flow of gases, to which the draft sensor immediately reacts.
3. Lack of outside air supply: the user must not forget that for normal draft it is necessary to provide air supply to the room from the outside. During the operation of the column, at least the window must be open. In particular, this applies to sealed double-glazed windows in metal-plastic frames.
4. Unfavorable weather conditions: the column may also go out due to the fact that a strong wind or whirlwind worsens traction or, conversely, sharply increases it, causing flame separation.

The presence of thrust is checked by bringing a paper sheet or a lit match to the “viewing window” of the column. If the smoke exhaust system is in proper condition, the flame will be drawn into the “window”, and the paper will be pressed against it.

Soldering the water heater heat exchanger

If a leak occurs in the radiator, you can replace the unusable part or repair the heat exchanger.

In the case of buying a new product, it should be borne in mind that the cost of such an element starts from 8500 rubles. At the same time, its acquisition is not always economically justified. The second option for troubleshooting is the restoration of the heat exchanger. To do this, the element must be soldered with solder using a soldering iron with a power of over 100W.

Because the temperature of the soldering pressure is much higher than the temperature of the liquid in the radiator tube, it will keep water from leaking well.

As a rule, the cause of leakage is the poor quality of the heat exchanger material. In this case, the area of ​​the micro-hole may acquire a greenish tint.

The sequence of soldering a gas water heater.

• Drain fluid from radiator. If necessary, its residues should be blown out with a compressor.

• Clean the fistula with sandpaper.

• Wipe the surface of the element with a rag, which must first be moistened with a solvent.

To solder the element, rosin is used as a flux.

Heat the solder with its subsequent build-up to the place of the leak, while its thickness should not exceed 2 mm.

After that, it is necessary to install the restored device in its original place and connect it to the system.
