Consider a possible self-repair of Amin's geysers.
It is advised to buy expensive alkaloid batteries, they will last several times longer than ordinary salt ones. The battery compartment is located on the bottom right side, you do not need to disassemble the water heater for replacement. It is important to observe the polarity when installing, for which you remember which side the previous batteries were on.
The second reason may be the wrong location of the ignition electrodes. Over time, under the influence of frequent temperature changes, some parts of the water heater are slightly deformed. For example, the ignition wires may sink lower or move away from the burner.
Then the spark simply will not reach the gas stream. It is necessary to remove the casing, visually inspect the location of the ignition elements and, if necessary, bend them. You can see how they should be located initially in the operating instructions.
If the exhaust gas sensor is triggered, the column will go out almost immediately. The reason for this may be a clogged chimney or active ventilation over the stove, into which the burnt gas leaves the column.
Such problems will not arise if you have a turbocharged model, for example, Amina VPGU-24 Coaxial-B. It is equipped with a coaxial chimney with a fan. It takes air from the street and forcibly discharges the exhaust gas outside.
The reason for not igniting may be a weak water pressure. To begin with, it is checked what pressure is in the water supply system; for this, a cold water tap is opened. If it is weak, you should wait or call the utility company with a complaint.
If the pressure is normal, you need to adjust the pressure in the device itself. This is done with a valve on the body, which is marked in blue. The less you set the pressure in the column, the less pressure is enough to ignite it.
The flame will not ignite if the membrane in the water block is deformed or torn. When the valve is opened, pressure acts on it, it bends and moves the stem, which opens the gas. Since it is made of rubber or silicone, over time it stretches and the gas either does not open at all, or the flow is very weak.
To replace it, you need to disconnect the water unit from the water inlet pipes and the heat exchanger and remove the bolted cover. In Amin's water heaters, the water unit is connected to the gas unit and is located horizontally, it is not at all necessary to remove it. It is best to buy a new membrane when you already have a damaged one in your hands in order to accurately select the size and model.
Despite the widest range of electrical heating appliances on the market, the gas water heater is still one of the most popular means of heating a house and providing it with hot water. This is a fairly economical option, since it allows you to simultaneously provide several drainage points in the house. Another advantage of gas water heaters can be considered the fact that they allow you to use hot water, practically unlimited, without any restrictions.
The geyser device looks like this.
Two pipes are connected to the gas column. The first of them is designed for gas supply, the second - for cold water supply. In addition, a pair of burners is located at the bottom, one auxiliary and one main.
Important! The device of the gas column can be different, depending on the method of ignition - it (ignition) can be electronic, manual and using a piezoelectric element.
Such devices are designed to provide domestic and industrial facilities with hot water. The essence of their work is quite simple: cold water from the pipeline enters the column heat exchanger, where it is heated by burners (they are located under the heat exchanger). As you know, fire needs oxygen, therefore, so that the burners do not go out, the column is connected to the ventilation system of the house / apartment. The exhaust gas is eliminated by means of a special chimney, which is combined exclusively with a gas water heater.
All the described types of columns function somewhat differently.
So, if the device is turned on manually, that is, the gas has to be ignited with matches, the burner will ignite from the fact that you turn the fuel supply valve. Although it is worth noting that such designs have become outdated a long time ago. Modern designs are equipped with either an electronic ignition or a piezoelectric element.
New models are activated at the touch of a button located on the front panel of the device. Piezo ignition creates a spark that ignites the pilot. In the future, everything happens in automatic mode - the tap opens, the column lights up, hot water begins to flow.
If the gas water heater is fired up electronically, then it is perhaps the most reliable and durable device. The system is turned on by means of a pair of batteries supplying the charge necessary for the formation of a spark. No buttons, no matches, the only thing you need to do to turn it on is to turn on the tap. In most cases, batteries last a very long time because the energy required to charge is minimal.
The use of gas water heaters, however, like any other equipment, is accompanied by malfunctions, frequent or rare. At the same time, there are such malfunctions that can only be eliminated by specialists who have the necessary knowledge and admission for this. But there are those that can be easily eliminated with your own hands, so we will consider them.

The most "popular" type of failure is that it simply does not turn on. If it has an electronic type of ignition, then you can easily solve a similar problem - just check the batteries and, if necessary, replace them with new ones. Often, such troubles overtake the owners a year after the purchase, since the batteries last mainly so long.
Also, when using a gas water heater, it may happen that the water in it does not warm up, or it warms up, but not well enough. Often the cause of such problems is the water unit, or rather, its defect. As a result, the membrane stops responding to pressure changes in the water supply system. And if this membrane stops stretching under the pressure of water, then, as a result, the gas valve will not open, or it will open, but not completely. To solve this problem, you should at least in general terms know the device of the gas water heater, because the defect can be of several types.
If salt deposits have accumulated.
If the system is clogged.
If cracks have formed, etc.
To eliminate such a problem, you must first of all disconnect the column from the gas supply, then clean the water block and check the membrane.
If the internal elements of the device are covered with soot or dirt, then this can also lead to failure. To solve this problem, you must remove the outer casing of the device, then clean each of the elements using a vacuum cleaner.
The next sign that the gas column has stopped working correctly may be the burner decay immediately after switching on. This happens due to the fact that the ventilation channel is clogged. Modern models of gas water heaters are equipped in such a case with special sensors that will inform the owner if there is no traction. After that, immediately turn off the gas supply. Next, the chimney should be checked. For this, the plug is dismantled and everything that has accumulated there is removed.
Important! You can check the draft of the chimney in the old "old-fashioned" way: bring a lighted match to it. If the fire on the match deflects in the direction of the chimney, then everything is in order with it. If this did not happen, then he needs a complete cleaning.
It is for this reason that the gas water heater should be inspected annually - this is the only way it will work correctly.
We also advise you to familiarize yourself with the basic requirements.
Modern gas water heaters are small and compact, so they can be placed in almost any convenient place. Their service life depends largely on how correctly they are installed and used in the future.
As you know, the device of the gas water heater is such that it has to work with a rather dangerous fuel. For this reason, during installation, make sure that, God forbid, there is no gas leak. If you cannot, for one reason or another, take care of this, or, even worse, cannot eliminate all the leaks, then further operation will turn into a dangerous activity, which sooner or later can lead to an explosion.
For this reason, it is categorically not recommended to install a gas water heater with your own hands. It is better to have professionals who have all the necessary skills, experience, and the appropriate equipment to do this.
So, for installation, you need the following tools:
dowels;
magnet and salt filter;
drill;
the required number of taps;
pipeline;
chimney corrugation;
gas pipe;
Mayevsky valve;
actually, the column itself.
The device is installed only in the kitchen and only on the wall, which is made of refractory material. The distance from the column to the wall surface should be at least 2 centimeters, if it turns out more, then this is even better. An asbestos sheet should also be laid here, which must have a minimum thickness of 0.3 centimeters.
Important! The apartment / house must have a chimney that will remove the products of gas combustion. It will consist not only of vertical, but also of horizontal sections, and on them it should go at a slope (approximately 0.2 centimeters per each running meter).
So that the pipeline does not accidentally burst, the gas column should be installed only when the water is completely drained from the system.
But editing, as we have already said, is not the most important thing. It is also important that the device is used correctly, for which certain operating rules must be followed. If you do not do this, then even the most expensive and high-quality model will soon break down. So we want to prevent this from happening. Firstly, we must not heat the water to a temperature that would exceed 60 degrees.The fact is that too high a temperature will lead to the formation of salt scale on the walls of the heat exchanger. The result is more frequent cleaning or, even worse, replacement of the heat exchanger.
In addition, we can damage the structure of the heat exchanger by using too hard water. To avoid this, the water should be softened using special means, or a special filter should be installed in the system.
Finally, it is not recommended to dismantle and clean the gas water heater with your own hands, because, as we have already said about this, professionals should deal with this procedure. Doing this with your own hands is extremely dangerous.
If you decide to purchase a geyser device for yourself, then pay attention, first of all, to the power of the model you have chosen. It should be enough to provide all your family members with hot water. The power of almost all modern models fits into the range from 3 to 60 kilowatts.
Important! The more powerful the gas water heater, the more water it will be able to heat up within a certain period of time.
The average “cell of society”, consisting of four people, needs a device with an average capacity of 16-24 kilowatts. It is more than enough for the dishes to be washed and everyone was able to take a shower. Even if the device has a low power of 16 kilowatts, it will be able to give 10 liters of hot water, which is enough to be able to wash and wash dishes at the same time. Of course, if you can, then buy a column with a capacity of 24 kilowatts, since it can provide 24 liters of heated water.
In addition, it is advisable to take into account the water temperature that a specific model can provide. For its designation, the Latin letters DT are used. For example, if water is already supplied to the heat exchanger at a temperature of 12 degrees, then it will heat up to 24 in it. therefore, it can be used even without preliminary dilution.
Today there are models that are capable of heating water even up to 50 degrees. Their power, as well as the cost, is an order of magnitude higher than conventional models. For this reason, if several plumbing elements are simultaneously connected to the system at once, then it is better to purchase a more powerful column so that it can provide them all with hot water at the same time.
Also, when buying a gas water heater, see if it is equipped with safety sensors. They are of the following types:
overheating;
damping of the burner;
burning;
reduced pressure;
temperature;
sudden interruption of water supply.
And remember: gas water heaters are only allowed to be installed in the kitchen! Installation of a gas water heater in the bathroom is prohibited! Unless she (the bathroom) meets all existing requirements.
So, we have analyzed what a gas water heater is, what are its features, what malfunctions may arise during operation and how to fix them later. We only note that such devices are extremely economical, especially in light of the ever-increasing utility rates. And the last thing: do not forget that prophylaxis of the column's performance should be carried out annually.
I wrapped the microswitch, which is under the flow sensor rod, in plastic wrap and now it is not afraid of leakage. And my leakage is so small that I couldn't see the drop nirazu, and the dampness still limescale the microswitch button, so that it did not come out of it and did not turn on the electronics. The microswitch can be easily removed from the bracket with two small screws.
I have a problem with a Selena gas water heater. As soon as the lid in the battery compartment is closed, the gas immediately ignites even when the water is closed. To heat the water, I first open the tap with water, then close the battery compartment lid.To turn off the gas in the column, I open the battery compartment cover. I called the master, changed the microswitch, but it did not help. The foreman cannot determine the breakdown. Who knows how to fix it, leave a comment, please.

Such a complex device as a gas water heater serves for quite a long time, care and operation is carried out according to the instructions attached to this unit. But all things deteriorate and sometimes minor or major repairs of gas water heaters or their prevention are necessary. As well as replacing some of the components of the gas column.
The internal structure of flow-through gas water heaters is of the same type and almost does not differ from different manufacturers. The main difference may be in additional options (display, automatic gas ignition, second temperature sensor, etc.), in the appearance of the device or in the design.
This is a gas column heat exchanger, it may look different from different manufacturers, but the principle of operation is the same.
A heat exchanger is installed inside - a finned copper tube through which a water flow moves. The burner standing under the heat exchanger heats up the tube and the water passing inside it heats up. With a low water pressure or its absence, the incoming flow is blocked by a valve (curtain), to which a spark ignition switch is attached. This is for fire safety.
To repair a faulty gas water heater or prevent a gas leak (if you smell), you need to call a gas water heater repairman. But if you decide to call the workers of Gorgaz, then do not think that they will immediately come, sometimes they refuse to come, explaining that the repair should be carried out by the company (or store) that installed the gas water heater.
Now a lot of "left" firms have divorced. and calling the workers of such organizations to their homes brings a number of other problems. Many craftsmen, seeing your incompetence in this area, find non-existent faults in the gas column or deliberately raise prices.
To increase the safety of the population, it is prescribed that malfunctions associated with gas equipment be eliminated by employees of the relevant service. But there are some problems that you can fix yourself. If you know how to hold the tool in your hands, you can repair the gas water heater with your own hands.
It is not very difficult if you know the typical problems of these water heaters. Below we will tell you about the most common of them and show you how to fix this or that breakdown. And let's start by setting up the unit.
Adjusting the height of the burner flame - the closer to the maximum the hot water is.
Not all masters know how to properly set up a gas water heater and simply don’t do it, leaving it as it is (by default). But we do not recommend leaving the factory settings and making adjustments yourself.
Set the gas and water knob on the heater to minimum.
Open the gas and water supply valves on the pipelines.
Open a hot water tap and adjust the water pressure you need using the knob on the gas water heater.
Wait 1-2 minutes and measure the temperature. Use the gas knob on the column to increase the flame, thereby increasing the temperature of the water to the one you need.
When the water temperature is comfortable, you can leave all adjustments alone and use the water.
In the future, you can adjust the temperature with another knob (supply of heated water).
This is a membrane in the gas column, if it fails, then the unit stops responding to the pressure of water.
When adjusting the speaker, sometimes unpleasant moments arise. The new column either turns on at a very low pressure, or does not want to start at all. It depends on the increased or decreased water pressure in the pipeline and is eliminated in the following ways.
With our water quality, the heat exchangers in the gas columns are clogged with scale quite quickly and very much, which reduces their thermal conductivity and increases gas consumption.
The longest, in time, process - cleaning the main tube (radiator) from deposits arising from heating tap water. If you turn the gas knob all the way, and the outgoing water is barely warm, then this indicates that the heat exchanger is clogged with ordinary scale, which does not transfer heat well.
This happens quite often in the case of a gas water heater without auto-ignition (with an igniter). Scale also forms if you set the water heating temperature too high. The unit overheats, the tube (radiator) heats up to 80-850, which contributes to the rapid (a little over an hour) the appearance of scale. Isn't it better to just turn off the speaker in time? Then there will be no problems, because 40-600 are enough for all washing and washing processes.
Check the inlet cock or valve before starting work on the heat exchanger. Maybe the whole reason is their clogging. But if they are in good condition, it is necessary to get rid of the deposits in the tube.
There are two ways to deal with the scale problem. We'll look at both options.
The Cillit KalkEx cleaning system does its job pretty well. With its help, you can quickly clean any boilers from scale. Unfortunately, it is not very accessible for ordinary users of gas water heaters.
This is an expensive method using a special device. (Cillit KalkEx) and a set of special preparations for flushing. Your speaker does not even need to be removed from the wall. You just need to disconnect the water hoses (inlet / outlet).
The purification device is connected to the column, and it runs the heated reagents in a closed loop (in a circle). Scale under their action decomposes, is washed out and drained.
Cheap but time consuming and laborious process ... For its implementation, it is necessary to disassemble the water heater almost completely and then rinse it manually.
The following materials and tools will help us with this:
open-end wrenches (set);
screwdrivers (Phillips and regular);
paronite gaskets (set);
rubber hose;
vinegar essence or anti-scale agent.
To remove the heat exchanger, proceed as follows:
first, we block the access of cold water;
then we remove the external elements that prevent disassembly (knobs of switches, regulators);
remove the casing, and for this we unscrew the screws located on the rear wall of the unit, lift and remove the cover;
we open the "hot" tap;
unscrew the supply pipe from the heat exchanger and move it aside;
After the water has completely disappeared, we put the hose on the heat exchanger tube and raise it above the column level. Slowly, pour the solution prepared by us into the hose and leave the column for 4-6 hours.
Next, you need to slightly open the water supply tap and watch the water that will come out of the column, if you saw a lot of scale, then our work was not in vain - we got rid of it ... If there is no scale in the outgoing water, then we repeat the whole process again.
The failure of a water heater can occur for many reasons. We will list the most likely ones:
The simplest reason for this trouble is the lack of normal draft in the chimney. If the chimney is clogged and there is no "draft" in it, then the column may not ignite.
To check for a malfunction, you can bring a piece of newspaper, a napkin or a lighted match to the chimney. If they flutter, then the cravings are in order. Otherwise, you will need to clean the chimney.
If the device (only in units with auto-ignition from batteries or an electrical network) does not ignite, then it is all the fault of the discharge of the batteries or the malfunction of the wires, the igniter unit. Eliminated by inserting batteries or checking the electric ignition system.
Failure of the igniter system can occur from poor pressure water. Open any tap with cold water and check the pressure, if it is weak, you can call the ZhEK and find out what the problem is.
If the column does not ignite when water is supplied or only turns on at a very high pressure, then the problem is most likely in the membrane, which, due to wear, reacts poorly to the water passing through it. In this case, it must be replaced.
This is a temperature sensor that measures the temperature of the gas column during operation, preventing it from overheating.
A temperature sensor is installed on each gas column, which makes sure that the column does not overheat in the event of a failure the column may turn off spontaneously during operation ... It usually looks like this:
After normal operation, for some time, the heater “stalls” for 20 minutes. After this time, it can be turned on for the same period of time. The malfunction, as a rule, is seasonal and appears only in summer or winter with closed windows.
The device turns off when it wants and then does not light up ... This can happen when the sensor wire is shorted to the body. Check wires are intact and well insulated.
In order to check the sensor itself for operability, two contacts should be removed from it and short-circuited with a needle, a paper clip, a piece of tin. If the gas appliance turns on and works, the sensor must be changed.
If you see similar spots on your column, then be sure that it is leaking and needs repair.
This malfunction can occur mainly in gas water heaters that have been operating for a long time. The two main reasons for the leak are:
Tubes (bends) or gaskets in the joints are cracked.
screwdrivers (cross and regular);
open-end wrenches (set);
solder with rosin;
a vacuum cleaner;
solvent;
"Skin".
Due to the harsh operating conditions, the radiator or bends can burn out and holes appear on them. If you have determined where the leak is, then you can repair the small hole with an ordinary soldering iron.
Preparing the gas water heater for repair
Drain all liquid from the system - open only the hot water tap, unscrew the nut on the cold water inlet pipe, and most of the water will flow out;
Remove the radiator completely;
Examine the entire tube. - if you see "greenery" - clean and inspect these places for cracks.
Soldering a heat exchanger does not always give good results, here a lot depends on your skill. If the soldering is poor, the heat exchanger will quickly flow again.
When you have found the leaks, you need to do the following:
clean the holes found with "sandpaper" and immediately wipe it with a cloth and solvent (this will remove the remaining grease, carbon deposits and dirt);
using rosin with solder, tin this place with a 100 watt iron (in the absence of rosin, use aspirin);
rub the crack or hole with solder, and after it cools down, add more tin (the layer should be 1-2 mm).
Replacing flexible hoses of this type does not require special skills; anyone can do it with a wrench.
Very often, leaks are formed in the places where the outlets are connected to the heater from the outside or to the internal assemblies of the column. All connections are made by "American" with gaskets inside.
Due to constant heating / cooling, the rubberized liners either melt or lose their properties and harden. Cracks appear in them, along which water flows.
It also happens that the flanges on the pipes crack over time - in this case, you need to replace the entire pipes.
Be sure to change the batteries in the gas water heater in time, because if they are dead, your column will start to emit pops when it is turned on. Also, due to dead batteries, the column may turn off spontaneously.
These startup and operating sounds indicate the following:
a little air got into the system (into the burner) due to the low gas pressure, which generated a microexplosion;
the flame breaks down due to the high pressure of the gas;
nozzle blockage;
low draft of ventilation;
the batteries are dead.
On your own, you can only eliminate the malfunctions described in the last two points.
This can happen for several reasons.
The simplest reason is incorrectly selected gas water heater ... You have saved money and bought a low power heater that is unable to meet your hot water needs.
The second reason is the low gas pressure in the pipes (in the apartment). Call gas workers to check the system.
The third reason is the usual blockage (jet, filters, scale, hoses, etc.), some types of which are described above. You can check this by the color of the fire, which changes from time to time. This is evidenced by the presence of soot.
You can only adjust the temperature and clean the column yourself.
Any professional will tell you: "a gas water heater is a potentially dangerous equipment, so you can only entrust its maintenance and repair to a qualified specialist." However, the ability to understand which element is out of order and what it can lead to will definitely not hurt.
DIY geyser repair
In addition, you can deal with the elimination of some malfunctions that do not specifically affect gas equipment on your own. Read the description of typical breakdowns and recommendations for action in case of their detection.
Gas column device
Equipment can stop igniting for several reasons.
Gas column device
First of all, you must make sure that the igniter is working properly. If it does not light up, contact your gas service. A specialist will clean or replace the failed element. You cannot touch it yourself - it is dangerous.
Gas column device diagram
In modern units with electronic ignition, in the absence of ignition, gas ceases to be supplied - it is cut off by a valve. The user becomes aware of this through the corresponding indicator. In some situations, this problem can be solved by simply replacing the battery. Check this point in the instructions.If the manufacturer does not give such recommendations, it is better to immediately contact the gas service or a third-party repair service.
At one point, the column may not light up
Battery pack for igniting the column
The column will not light up if there is no ventilation draft. To check the level of traction, we bring a strip of paper to the ventilation grill. If the leaf does not change its position, or if it does not change it sufficiently, there are obvious problems with craving. In apartment buildings, utilities are engaged in cleaning ventilation wells - contact them. You can do this yourself with the help of a metal brush tied to a flexible wire (hose, etc.) of a suitable length, however, utilities usually do not approve of such unauthorized actions.
Burners often fail to fire due to diaphragm wear. This structural element deforms rather quickly, the burner starting mechanism becomes less sensitive and does not work when the water is turned on. Even in expensive heaters, membranes wear out in 5-8 years - unfortunately, nothing can be done about this.
Often burners do not fire due to diaphragm wear
To check, turn on the water to maximum. If the column turns on with a strong pressure, the problem is definitely in the membrane. Replacement of this element can be done on your own.
To do this, do the following:
unscrew the fastening nuts from the water unit (usually there are 2 of them);
unscrew the fastening screws, due to which the water unit is held in the gas unit (usually 3 screws);
detach the halves of the assembly and you will see a rubber membrane. If it is not flat but noticeably deformed, replace it. To do this, buy a similar product from a specialized store. If possible, give preference to a silicone membrane - it will last much longer than its simple rubber counterpart.
At the same stage, you can check the condition of the water intake filter. If it is clogged, clean it or replace it with a new one. To clean, simply unscrew the nut from the water supply side, take out the mesh and rinse it or replace it with a new one, depending on the condition.
If the heater turns on but goes out, the problem in most situations is the bimetallic temperature sensor needed to protect the equipment from overheating. Also, due to malfunctions of this element, the heater may not turn on at all.
This problem has 2 main development scenarios.
According to the first scenario, the burner lights up properly, the equipment functions for some time without any complaints, and then goes out and for some time does not show any signs of life - attempts to ignite the heater do not lead to anything. Usually, after 20-30 minutes, the equipment turns on again and history repeats itself. This is due to the excessive sensitivity of the sensor. As a rule, it is "congenital", i.e. this is a factory defect. It is extremely difficult to do something on your own. It is better to immediately contact the manufacturer's service for warranty repairs.
According to the second scenario, the column may turn off randomly, and sometimes not turn on at all. The reason usually lies in the wear of the insulating material of the conductor of the bimetallic sensor. There is a banal short circuit to the case, as a result of which the safety valve is triggered, and the column begins to behave abnormally.
Contact the service center for warranty repair
It makes no sense to turn to gas workers - the defect is clearly not a "gas" one. You also don't need to try to get rid of the breakdown yourself - you can only break the unit. Contact the service center for warranty repairs.
Water comes out with a weak pressure
Most often this happens due to clogging of the column heat exchanger with scale. Prolonged “idle” ignitions of the igniter are usually the cause of clogging.The device heats up the heat exchanger to a temperature sufficient to cause the remaining moisture to evaporate.
There is no water flow, scale is not washed out of the heat exchanger, until the next turn on of the equipment, it sets, as a result of which the column ceases to function normally. Cleaning the heat exchanger usually saves. In advanced cases, it has to be changed.
For replacement, it is better to immediately contact the professionals, but you can handle the cleaning on your own. Prepare screwdrivers, rubber hose, open-end wrenches and paranite gaskets. Purchase a descaling mixture from a hardware store. Usually it is called that - antiscale. A more budgetary option is rinsing with vinegar essence. Work in this order.
First step. Remove the fittings and the casing from the heater one after the other.
Second step. Turn off the inlet water and open a hot water tap, preferably as close as possible from the column.
Step three. Unscrew the water supply pipe from the heat exchanger and then move it to the side. After unscrewing the nut, the column heat exchanger will begin to release water. In total, about 1 liter of it will be drained.
Fourth step. Place a hose of a suitable diameter on the inlet of the heat exchanger and lift it just above the heater. Insert an ordinary funnel into the fixed hose and start slowly pouring in the prepared solution in a thin stream (instructions for preparation are given on the package). There is no need to rush. If you pour it too quickly, the antikipine will simply push it back out, and you are unlikely to like it.
Flushing the gas column heat exchanger
Leave the cleaning agent in the heat exchanger of the heater for 2-3 hours (usually the required time is indicated on the packaging).
Place a suitable container under the water tap and carefully re-feed the heater. Observe what comes out of the hose. Was there a lot of slurry coming out, and then the head returned to normal? Things are good. Otherwise, flushing will have to be repeated. Usually, the need for re-rinsing arises only when using vinegar essence. Anti-scale in most situations copes with the first time.
In such a situation, it is better to immediately contact a professional. He will perform the adjustment, which is extremely difficult to make without knowledge of the matter, and the column will start working normally.
You can find out the reasons for the appearance of such a malfunction for general development. There are two main reasons:
the gas comes under too much pressure. The heater ignites too actively, which leads to the breakdown of the fire;
the gas flow is too low. Air enters the heater burner, resulting in a microexplosion, which is interpreted by human hearing as cotton.
The column does not heat up the water sufficiently
This usually happens due to the insufficient power of the gas column. The user begins to demand more from the equipment than it can do.
There are two options for solving the problem:
we stop abusing and do not open hot taps at the same time at all points of the water intake;
buying a more powerful speaker.
Also, inadequate heating of the liquid can occur due to the clogging of the burner. Look at the color of the fire. Under normal conditions, it is bluish. If the flame turns yellow, contact the gas industry. Such repairs can only be entrusted to a professional, tk. this is already a "gas" breakdown.
The problem is more than serious. Don't even think about any hand-made repairs. Turn off the heater, turn off the gas cock, ensure that there is adequate ventilation at all times, and call the gas service immediately. The arriving team will assess the problem and take appropriate action.
Now you know the main malfunctions of the gas column, and you know how to behave when they appear. The main thing is to remember about safety.There is no need to try to fix breakdowns for which you do not have enough qualifications - this can lead to irreparable consequences.
