Water heater oasis DIY repair

In detail: do-it-yourself repair oasis water heater from a real master for the site my.housecope.com.

An electric boiler is an effective solution to the problem of hot water supply for a private house. Such equipment, however, like any other, breaks down periodically.

If serious breakdowns have to be eliminated in a service center, then any more or less experienced craftsman can perform a small repair of the water heater with his own hands.

To minimize problems with the device, you should study its design and principles of operation. Usually, in private households, not flow-through, but storage models are used, which make it possible to use electricity more efficiently. Such a device consists of a heat exchanger tank, inside which a heating element is installed - a heating element, connected to the power supply.

An important part of the device is the thermostat. This element allows you to maintain a constant water temperature inside the storage tank. The water is piped to the heat exchanger. If its temperature is too low (and this is usually the case), then the thermostat gives a signal and turns on the heating element.

The water is heated until it reaches the required temperature. After that, the thermostat works again and turns off the heating element. Hot water is taken from the tank and replaced with cold water, the heating process is repeated over and over. This is a general diagram of the device and operation of a conventional storage water heater.

Flow models are arranged somewhat differently. They do not heat a static volume of water, but a stream. They use more powerful heating elements that start working when the water is turned on and stop when it is turned off. To study in more detail the operation and structure of a particular model, you need to carefully familiarize yourself with the accompanying technical documentation.

The heater tank is a sturdy stainless steel container, one or two millimeters thick. No matter how resistant this material is to corrosion, nevertheless, these processes periodically arise and develop, which leads to the flow of water from the device. One of the most common causes of such breakdowns is electrical corrosion.

To prevent it, you need to regularly, i.e. Replace the internally mounted magnesium anode annually. This element is specifically designed to prevent electrical corrosion. Over time, it wears out, and the owners of storage tanks lose sight of replacing this important part.

As a result, the tank, which has served well for some time, suddenly starts to leak. The incorrect state of the magnesium anode can also affect the state of the heating element. The outside of the storage tank is usually enclosed in a metal or plastic housing, and it also has a heat-insulating shell that prevents heat loss.

Damage to the outer shell and insulation is rare, usually due to careless handling of the device. Cracks and chips on the body of the water heater may not interfere with its operation, but this will lead to a deterioration in the properties of the heat insulator, and will negatively affect the functioning of the device as a whole.

Cold water inlet and outlet pipes - for hot water usually do not cause any problems if the installation of the heater is done correctly. Usually, a water heater is equipped with two thermostats, one of which is designed to control the water temperature, and the second monitors the state of the first device.

Sometimes a third thermostat is also used, which determines the good condition of the heating element. In any case, the broken thermostat will have to be completely replaced. There are capillary, rod and electronic types of thermostats.Their design is different, but the principle of their work is the same.

The insulating gasket not only serves to seal the connection between the elements of the water heater, it is also necessary as an electrical insulator. It is recommended to replace this element regularly at every maintenance of the water heater.

The thermostat shows exactly what temperature the water inside the device is heated to. If this element breaks down, the water heater will still perform its functions, although data on the degree of heating will not be received.

Breakdown of heating elements is a typical problem for both flowing and storage water heaters. This element works under high stress and therefore wears out quickly. If the power supply is connected, but the water in the tank does not heat up, most likely the problem has arisen with the heating element.

First, you should check if electricity is supplied to the heating element and the thermostat. In the places where the cable is connected, the presence of voltage is checked with a tester. If there is no voltage, you may need to replace the cable itself or check for a power outage throughout the house.

If there is electricity and the cable is working properly, then problems have arisen with the heating element, which will have to be replaced, or with the thermostat. To figure out what exactly broke, you need to remove the thermostat and check it with a tester. Testing the health of the heating element is carried out as follows. First, the measuring scale of the device is set to the interval of 220-250 V. Then the resistance is measured at the terminals connecting the heating element to the mains.

If there is voltage, disconnect the heating element from the network and check the potential at the terminals of the heating element. Lack of response from the tester will indicate that the device is defective. If there is a reaction, you need to continue the diagnosis. First, disconnect the water heater from the power supply. Then the heating element is disconnected from the thermostat so that the contacts of the heating element remain not isolated.

Tester contacts are applied to them and the reaction is monitored. If it is, the heating element is working, if not, it needs to be replaced. In this case, it does not matter what kind of numbers the tester produces, only the presence or absence of a reaction is important. These troubleshooting methods are suitable for both storage electric water heaters and flow-through models.

To check the serviceability of the thermostat removed from the water heater, you need to set the adjustment knob to maximum and measure at the inlet and outlet of the device. If the needle of the tester remains calm, i.e. its position does not change, which means that the thermostat is faulty and needs to be replaced.

If the arrow deviates, then you need to continue testing. Now you should set the minimum position on the thermostat and attach the test leads of the tester to the contacts. It will not be easy to continue the diagnosis alone, the probes will have to be fixed or asked someone to hold them in the correct position for a while.

After that, you need to take a lighter and heat the tip of the temperature sensor. If the thermal relay is triggered, the circuit will open, and the resistance on the tester's scale will sharply go down, then the thermal relay can also be considered serviceable. If the system does not respond to heating, then this element is damaged and needs to be completely replaced.

Occasionally, the water heater can stop working due to a blown thermal fuse as a result of dangerous overheating of the device. It is enough to correctly adjust the operation of the device for it to start working as usual.

If the check showed that both the heating element and the thermostat are in good order, most likely problems have arisen with the control board. It is almost impossible to repair such an element at home. It will have to be replaced with a new one, and you will have to use the help of a specialist who will help you set up the electronic equipment.Most often, you just need to contact the service center, where the required element will be selected and installed correctly.

A tank leak is a serious problem that cannot always be corrected on your own. In some models, either the tank or the entire heater will need to be replaced. Sometimes the leak can be sealed, but care must be taken to restore the integrity of the outer casing and the thermal insulation layer. Usually such measures are insufficient and short-lived, and soon the leak will reoccur.

The water heater tank most often leaks if:

damage to the internal tank has occurred;
the heating element has deteriorated;
leaky gasket.

If water flows at the place where the heating element is attached, it may not be necessary to repair the tank itself. A special gasket is installed in this place, the leak can be caused by its damage. The gasket is replaced and thus the problem is solved.

A water heater tank leak usually occurs due to neglect or untimely maintenance, which also includes the replacement of the magnesium anode. Another common problem is lack of grounding. This can also lead to the development of corrosive processes and the occurrence of leaks.

If you need to replace the gasket or heating element, it is best to first dismantle the faulty element in order to take it with you and find an exact analogue. Obtaining parts by eye can result in unnecessary costs. This replacement is relatively straightforward. But if problems arise with the tank, you will at least have to contact the service center. Immediately it is necessary to find documents for the water heater and clarify the warranty periods and service conditions.

Regardless of the nature of the breakdown, before starting repair work, you first need to turn off the power supply, remove the protective cover, disconnect the wires, pipes and drain the water. Wall-mounted models are usually removed from the brackets. The protective cover that hides the place for connecting the electrical wires and the fastening of the heating elements may have a different position depending on the model.

On horizontal type devices, such an element is usually located on the left, on vertical heaters - at the bottom, and on small models - in front. On some devices, you first need to unscrew the main mounting bolt located in the center. Sometimes this element is hidden under a decorative sticker.

After that, you need to carefully remove the thermostat, and then remove the tubes of the temperature sensor. They must be handled with great care. If the integrity of the thermosensor tube is broken, liquid filler will leak out. As a result, the water heater will simply have to be thrown away and a new device bought.

If there are stickers on the body with the serial number indicated, they must be kept, even if it interferes with the maintenance and repair of the product. This can affect the manufacturer's fulfillment of the warranty obligations, as well as facilitate the work of the service center employees.

The fact that there are problems in the operation of the device may indicate some changes in the mode of its operation. For instance:

increasing the time for heating water to a predetermined temperature;
the appearance of unusual sounds accompanying the operation of the device;
the appearance of impurities in tap water, a change in its color, smell or taste.

If at least one of these signs is observed, the water heater should be cleaned immediately. To do this, you will have to perform the following operations:

Disconnect the device from the power supply.
Remove the protective cover.
Disconnect the contacts of the electric wires.
Shut off cold water supply.
Remove residual water from the tank using a hose.
Unscrew the screws that hold the heating element.
Remove the heating element and descale it.
Clean the inside of the drive from dirt and scale particles.
Rinse the device thoroughly.
Check the health of the magnesium anode.
If necessary, replace this element immediately.
Wait until the cleaned tank is completely dry.
Install the heating element in place.
Reassemble the device.
Check the tightness of all fasteners.
Connect the water heater to the power supply.
Check for grounding.

The heating element should be removed from the tank carefully, the bolts may be too stubborn, sometimes the heating element is difficult to remove due to too much scale layer. The heating element is cleaned by mechanical or chemical means, as is the removal of contaminants from the tank. If a large amount of scale is found inside the device, you should consider revising the operating mode of the water heater.

This phenomenon is often observed when the device has been operating at maximum power for a long time. It is recommended to set the maximum heating temperature not higher than 60 degrees in order to increase the life of the device and reduce the number of breakdowns. If the body of the heating device shocks, it is possible that the heating element is deformed and ruptured, or there are breakdowns in the control system.

It is not so difficult to repair a water heater when it comes to replacing some of its elements. In the event of a serious breakdown, it would be wiser to contact a specialized service center. Correct use of the device and its timely maintenance will save you many problems and costs.

Today we will consider the repair of the Chinese gas water heater Oasis with our own hands step by step. The most common malfunction of the Oasis gas column is the failure of the water block membrane. In this case, the Oasis usually does not light up. It is not difficult to identify this malfunction, and repairs can be done by hand. We will consider the disassembly of the column below. To begin with, remove the column housing, put the water flow regulator on the water block of the column to the fully clockwise position and open the hot water tap. In this case, we look at the microswitch, which is located in the middle - between the gas and water block of the column. If the membrane is working properly, then the rod of the water block presses on the tab, which releases the microswitch button, respectively, the column should crackle and ignite. If the foot comes off well from the microswitch, but there is no crackling sound, then the microswitch is most likely faulty. It can be checked by disconnecting the connector and closing the contacts.

This means that a malfunction of the water block of the geyser has been found and you can consider how to repair the Oasis geyser with your own hands, disassemble the column. So, let's start step by step:

1. Remove the handle 1 from the gas water heater to adjust the gas supply to the gas block, handle 2 to adjust the water flow in the water block, and handle 3 to the switch of the gas water heater for winter / summer mode.

2. Find two self-tapping screws on the bottom right and left for securing the column cover to the back wall of the Oasis column and unscrew them. Usually it is inconvenient to get to the screws. Next, remove the front panel of the Oasis gas water heater from the upper hooks of the back wall of the column.

3. Carefully, so as not to break, disconnect the connectors of the wires that go to the display of the column from the control unit and from the temperature sensor.

Poor water quality is considered to be the main cause of boiler breakdown. Because of this, scale forms on the surface of the heating element, the inner walls of the tank are susceptible to corrosion, which in the future entails more serious consequences and expensive repairs in the service center. In addition, the water heater may stop working due to improper connection to the power supply and the hot / cold water circuits.

As for the latter, when connecting the boiler, it is imperative to install a safety valve between the branch pipe coming out of the tank and the cold water supply pipe, which will protect the tank from rupture during a water hammer.You should also make the connection according to the instructions and, no less important, do not confuse where-what is connected. Sometimes situations arise that, if installed incorrectly, the water heater does not collect water. Please note that you should not panic in this case. It is better to take another look at how to properly connect the equipment to the pipes and, most likely, you will understand why your water is not collected.

So that you understand how to repair a storage water heater in different conditions, then we will separately consider how to repair all possible breakdowns with our own hands.

If the boiler does not heat the water to the required temperature, but still makes noise when turned on, it means that scale has formed on the heating element, which you need to clean yourself. This is not difficult to do, you just need to disconnect the equipment from the network, drain the water from the tank and disassemble the case to remove the heating element. You will not have any difficulties with disconnecting the plug from the outlet, but draining the water can make the repair a little more difficult. Immediately we recommend watching a video lesson, which shows a simple method for solving this problem:

After you empty the tank, you will need to disassemble the boiler yourself. To do this, carefully disconnect all fastons connected to the thermostat and unscrew the bolts, which are usually 6 pieces.

During the removal of the heating element, a little more water will pour out, which remains in the tank. It is recommended to clean the heating element itself immediately, before it is wet and the scale deposits have not hardened. We recommend using special cleaning agents that can be sprayed onto the heater. After a while, the deposits are effortlessly scraped off with a wooden spatula or even a blunt knife. Also, for repairs, you can boil the heating element in a bucket with the addition of special acid to the water, which will effectively solve the problem. To get rid of limescale for sure, we advise you to use fine-grained emery paper ("sandpaper") to clean the tubes to a metallic color.

Simultaneously with the repair of the boiler, which heats the water for a long time or weakly, it is recommended to replace the magnesium anode, which protects the tank from corrosion. To do this, dismantle the worn out rod and purchase exactly the same one in order to replace it yourself!

After that, you need to assemble the boiler in the reverse order and check whether it was possible to repair the weak heating of the water. Do not forget that first of all you must fill the tank completely with water, then connect the plug to the mains and start.

We draw your attention to the fact that there is a situation when the boiler does not heat the water, because the heater is broken. In this case, self-repair is that you need to ring it with a multimeter, setting the resistance measurement mode. We will tell you about this below!

If the light on the boiler is on and the water does not heat up, then it is likely that the heater, which we talked about above, is not working. It is quite simple to check it at home, you need to install the tester probes on the contacts of the heating element and see the resistance on the display. With a working heater, the resistance can vary between 0.4-0.7, as shown in the photo below. If you see "1" on the display, then there is a breakage and you need to replace the part with a new one, because it is almost impossible to repair it.

By the way, if the boiler beats with current or when it is turned on, the RCD is turned off by itself, then the cause of the breakdown, again, is in the heater from which the leak occurs. You can check the malfunction by connecting one probe to the contact of the heating element, and the second to the tube itself. You will see “1” on the display, the part is in good order and there is no need for repairs, a minus value or too large - replacement is required. In more detail about how to check the heating element with a multimeter, we talked in a separate article.

Another reason why the boiler does not heat the water or, on the contrary, heats up very much, is the failure of the thermostat.You can check it in two ways - with a tester or a lighter. Everything is clear with the tester, you need to act according to a similar method, but as for the lighter, everything is more interesting here. First, dismantle the thermostat and press the button on it (it is circled in the photo below). After that, the copper contact of the thermostat must be heated. If after some time the button returns to its original position (knocks it out), the thermostat is operational. If the thermostat does not work, you can repair the boiler that does not turn off or does not turn on by replacing this part with a new one. I would also like to note that there is no need to drain the water to replace the thermostat on the water heater. It is enough just to disconnect the equipment from the network and disconnect all the supplied wires.

Also, sometimes there is a breakdown - the temperature is not shown on the display of the water heater or the display does not work at all. In this case, check all the elements of the circuit and if you do not find an open circuit, most likely the control unit has broken. You will not be able to repair electronics with your own hands in the absence of experience and knowledge, so you will have to take the electric water heater to a service center for repair.

If you notice that water is dripping from the boiler, it is not always possible to repair it yourself. It is good if the cause of the leak is the wear of the seal on the flange. In this case, the gasket must be replaced with the same size, which will allow the breakage to be repaired. The situation is much worse if the water heater leaks due to the wear of the tank itself. Some advise to glue or solder the holes, but, as practice shows, after a short period of time you will still have to say goodbye to the boiler, because such leak repair methods are extremely short-lived.

That's all I wanted to tell you about DIY boiler repair. We hope that now you know what to do if an electric water heater is leaking, does not heat the water well or does not work at all. These devices do not have many problems and you can get rid of them by timely maintenance of the system. At least once a year, check the non-return valve and clean the heating element so that malfunctions bypass you!

Gas water heaters in everyday life are becoming an irreplaceable thing both in private apartments and in country houses and ordinary dachas. Manufacturers of gas water heaters nowadays make a good and not expensive product of our manufacturer, since today the water heater market is boiling and competition is very high.

Oasis gas water heaters are popular heating devices among consumers. These models are inexpensive designs. Includes economy, reasonable price and popularity. You can also read a lot of positive reviews about the Oasis gas water heater, which speaks of their quality.

In order to choose the right model for your home, you should pay attention not only to their advantages, but also to the weaknesses of the heating device. We also recommend that you pay attention when choosing customer reviews on Oasis gas water heaters.

According to the principle of operation, Oasis water heaters are divided into two types:

The mechanism of action and heating of water, depending on the type of device, will be different. Another type should also be highlighted - this is the Oasis Turbo gas water heater, as well as the Oasis turbocharged gas water heater. Most often they are installed in large organizations, apartments and large private houses.

All of the above devices should be installed where there are no stationary chimneys. All of these devices operate on mains power and do not require additional batteries. The work of such a column is carried out in the forced emission of combustion products. Turn the Oasis turbocharged gas column on and off by opening the tap. It can also be installed offline.

Advantages of Turbo gas water heaters:

Modern compact design;
Forcibly ejects combustion products outside;
The security system is built into the column itself;
The presence of a control panel and a liquid crystal unit on all models of Oasis gas water heaters;
High efficiency;
Simple and uncomplicated adjustment of the Oasis gas column.

Flow columns

Now let's take a look at the popular flow column. If you decide to install such a column in your home, then you don't have to worry about the fact that you will be left without hot water, even despite the small pressure.

Gas water heater manufacturer

It should be noted that Oasis water heaters are made so that they have different boiling water performance. In addition, we can say that the Oasis gas column device is made of a flow-through type. Such a column can produce from 5-15 liters of hot water within 1-2 minutes.

And here are the positive aspects of Oasis flow columns:

Constructions are included automatically.
This column does not depend on electricity, but works due to replaceable batteries.
Reasonable price for the Oasis gas water heater.
Understandable and legible instruction of the Oasis gas water heater.
The presence of a regulator in the column that controls the heating process depending on the outside temperature and what time of year at this stage.
Economical, which allows you to minimize consumer costs.

It should also be mentioned from consumer reviews that the manufacturer of the Oasis gas water heater constantly thinks and improves the quality of its products for the better.

The disadvantages of the Oasis instantaneous water heater is its high cost. Although the device is durable and quickly pays for itself to the consumer.

Cumulative columns

The storage and flow-through devices mentioned above are very different from each other in the principle of operation. If we talk about a storage heater, then the principle of operation is that the water in it is heated in a large tank. It should be noted that there is no such storage tank in the flow columns.

If we talk about the positive aspects, then they are as follows:

A simple repair of the Oasis gas water heater can be made by a person who does not have special skills.
There is always a lot of hot water.
Economy in work.

If we talk about the negative aspects of the Oasis storage columns, then naturally it has a large size and high cost.

Also, among the customer reviews, they constantly notice that it is problematic to place an Oasis speaker in a small apartment. It is better to buy it for those people who have private houses. It has a huge tank that can provide hot water to the whole family, especially the presence of such a device is necessary where there are small children.

Standard white gas water heater Oasis

As with any equipment that is constantly in operation, malfunctions of the Oasis gas column may occur. Below are some of the most common breakdowns and problematic situations with Oasis heating devices:

A factory defect is rare;
Initially, the equipment was installed incorrectly;
Improper operation of heating equipment, which often leads to breakdowns;
The Oasis gas water heater does not light up. There are many reasons for this. The main and first thing is to check if the igniter is on. If the igniter does not burn, it requires cleaning the jet, or its complete replacement. Another most common reason is that your Oasis gas water heater does not light up, the lack of draft in the ventilation duct. This can be verified very easily. Apply a sheet of paper to the ventilation duct, or light a match and hold it in front of the ventilation duct.

You can also remove blockages in the ventilation ducts with your own hands, and you can also call the appropriate utilities.

Also, consumers often complain that the Oasis gas water heater does not light up. In this case, first of all, you need to check if there is a spark. There is such a breakdown as the flame goes out if the ignition button is released.

View from the bottom of the gas water heater

In each case, you need to understand. Since the technical characteristics of the Oasis gas water heater are different. We recommend that you follow the Oasis geyser diagram before troubleshooting.

It may be that when you turn on the Oasis gas column, you can smell gas. This is a serious breakdown. Immediately you need to turn off the tap where you have gas supplied to the column. Provide room ventilation and call the gas service. In conclusion, I would like to warn you that we do not recommend disassembling and cleaning the gas equipment on your own.

Nikolay Vasilievich, 55 years old, Kostroma

My wife and I constantly live in a private house in the country. The crust in the village constantly has problems with hot water. We decided to purchase an Oasis gas water heater. The design pleased her. Fits into the interior of the kitchen. Copes with its task. This column runs on batteries and does not consume electricity, since this is important for us in a country house. My wife and I are happy with the purchase, we advise.

Vera Nikolaevna, 48 years old, Moscow

I live in a city apartment myself. first of all, I paid attention to the convenience and ease of installing a gas water heater. The purchased gas water heater Oasis pleased with its beautiful design. The controls are very simple. I independently change the water pressure needed, and also easily control the power of the device. On the screen, I have it liquid crystal, the temperature of the water is visible. And this is important to me. The price of the Oasis gas water heater made me happy. I do not regret that I bought it.

The day came when I started repair of the Oasis gas water heater, he has long since requested maintenance. Water has been dripping from it for a long time already, the display, when turned on, does not show the temperature of heating the water, but hieroglyphs of type 33, but in a mirror image. One of the adjustment knobs turned with great difficulty, the wife could not turn it. In order not to make a mistake while repairing the Oasis gas water heater, I had to call my acquaintance locksmith - an employee of the city gas industry. Explaining the breakdown of the water heater, I received an exhaustive answer and a list of replaceable parts. So, let's begin.Water began to drip into the Oasis gas column, flowing down from the Mikrik - an electronic micro switch and a temperature sensor. Based on this, the following spare parts were purchased.The micro switch was replaced because it was all sour (water was flowing down it) and not repairable.Membrane of the water seal of the gas column OasisThe membrane was intact, but since it was already compressed by the fixing cap, in order to avoid leaks, I decided to replace it.I needed it to display the temperature in numbers and not in hieroglyphs, especially since the sensor was leaking.Stem assembly for the Oasis gas columnAnd here is the culprit of the leak - the stock.After purchasing all the parts, we proceed to repair the Oasis column.We remove the three temperature adjustment knobs by simply pulling or prying them with a screwdriver. We unscrew the four self-tapping press washers at the top and bottom, two at a time - fastening the front panel. We disconnect the wires going to the display and that's it, the panel to the side. We take out the batteries from the power supply unit and unscrew the battery unit - one self-tapping screw from the bottom. In the next step, we unscrew the water inlets - two nuts on the back and on the right. Now you need a long screwdriver to reach the screws on the water valve through the ventilation ducts on the right. We unscrew the screws, remove the water supply and take out the water seal. Image - Water heater oasis DIY repair

Please pay special attention to the stock. You will see a small round washer on the new stem. When removing the old stem, such a gasket may remain in the body and be difficult to reach. There is nothing terrible in this. Just remove the gasket from the new stem and that's it. This gasket works for gas tightness and has no wear. So, we unscrewed the stem - we put a new one, put a new membrane, put a new micrik (I will not describe it - just a children's designer), in general, we put everything in place in the reverse order.Before installing the water seal, we change the temperature sensor, if necessary.

There is such a moment: when I began to unscrew four screws on the water seal, I could not unscrew one. I had to shoot together with the gas regulator. But that's a completely different story.

That is, in principle, all the cases. Repairing the Oasis gas water heater is not such a difficult thing. We collect all the parts in the reverse order of analysis. If something is not clear please write. I wrote an article a month after the repair - I apologize if there are minor inaccuracies.

PS ... I would like to add such information to the article after a year of observing the Oasis column: the temperature sensor began again to show numbers with hieroglyphs alternately. The indicated temperature on the display does not correspond to the real one. Enough for exactly one year.

Gas disconnection in the water heater began to occur with a delay. And this means the following: the rod moves tightly.

In this article, we will consider the most frequent breakdowns of the Oasis gas water heater with detailed repair instructions and possible repair schemes for the apparatus. To prevent damage to your device, you need to replace and maintain its elements on time.

Gas column radiator Oasis

Close the gas valve before starting any repair work on the appliance.

When you see that your column is leaking, the first thought is to replace the heat exchanger, but do not rush, the problem can be solved with much less financial losses, despite the fact that its cost is 30% of the price of the column itself. You can do this with your own hands using a soldering iron and solder. If you are worried that the solder will not withstand the temperature of the water that flows through the pipes, then in vain, the solder melts at a temperature of about 200 degrees, and the temperature in the pipe, as a rule, does not exceed 80 degrees.

Often, fistulas appear on the pipe, which is located on the outside of the heat exchanger. After finding a leak, before starting work, be sure to pour out all the water in it, if there is water, you will not be able to reach the required temperature at the leak. To do this, you need to open the hot water valve, unscrew the nut on the cold water pipe, suitable for the column. Due to the fact that the column is installed at a level higher than the tap, most of the water will drain, but not all. To completely remove it, use a purge with a vacuum cleaner or compressor. After all the water has been removed, the repair process can begin.

Use a fine grit sandpaper to remove any rust build-up from the leak, wipe the area with a cloth soaked in solvent to degrease the area and remove any dust particles. Soldering can be done with any brand of solder. The soldering iron must have a power of at least 100 watts and a soldering temperature of about 170 degrees.

To protect the solder from oxidation, rosin is used; in its absence, aspirin tablets can be used. Crush the tablet and pour on the adhesion site, or simply rub the tablet on the heated surface.

If the tin does not lay down in an even layer, but collects in drops, then the surface is not warmed up enough, or there is not enough flux.

To eliminate this problem, you need to use an additional heat source, or re-degrease the surface and treat with flux.

To prevent the fistula from appearing again, you need to provide a solder thickness of about 2-3 mm at the soldering point. Perform a visual inspection of the surface of the heat exchanger for green dots, if they are found, this is the first sign of a fistula. To eliminate the leak, perform the above procedure with them.

If the area to be repaired is on the side of the wall, then to carry out the repair you will need to disconnect all pipes suitable for it and remove the heat exchanger from the device.

One of the signals that a blockage has occurred is insufficient water heating.The cause of this breakdown is hard water in the water supply system, which prevents the water from heating to the required temperature, reduces the flow of water at the outlet, and, as a consequence, increases the gas consumption. The deposition process occurs when the heating water exceeds 80 degrees.

To remove limescale, you can use special liquids that are sold in the store. There are also devices with which cleaning is performed. The mechanism of action of the devices is simple, the device itself is a kind of reservoir with a built-in pump to extract water. The pipes of the cleaning device are connected to the pipes of the radiator of the gas column. The cleaning reagent is warmed up and pumped into the heat exchanger; it does not have to be removed from the column. Plaque gradually begins to dissolve in the reagent. However, they are quite expensive.

You can also carry out cleaning in a more economical way with your own hands, without using automatic tools. It is necessary to remove the radiator and remove all water from it. Cleaning is done using a commercially available reagent or prepared independently using vinegar or citric acid (dilute 150 grams of acid with 750 ml of hot water). The radiator is immersed in a tank filled one third with water, the heat exchanger tube is filled with the prepared liquid. It is necessary to pour into the pipe from the end of the lower loop in order to displace all the air. Place the container on the stove and bring to a boil, boil for about fifteen minutes, turn off and let cool. Then install it in its original place and connect it to the pipe that supplies water to the outlet of the heat exchanger, connect the hose, lower the other end into a sink or other container. Open the water tap, the flowing water will force out the existing solution along with scale. Repeat the procedure again if necessary.

At the moment of ignition, the protective mechanism of the device, located inside the device, is triggered and the gas supply is turned off automatically (why the Oasis gas column does not ignite and the troubleshooting methods are described at the link: https://my.housecope.com/wp-content/uploads/ext/830 /gaz-kolonki/firma/pochemu-ne-zazhigaetsya-gazovaya-kolonka-oazis-net-iskry.html).

If the device does not ignite, it is necessary to check the following possible most common causes of breakdowns:

There is no draft in the chimney. It can happen if a foreign object gets into the flue. To eliminate this breakdown, all ventilation pipes must be cleaned.
The battery is discharged, that is, the batteries, they may also have leaked. It is required to clean the slot where they are inserted, purchase and insert new batteries.
Insufficient water pressure. It is necessary to call the water utility and report the problem with the water. Check the water filters for dirt and clean them if necessary.

A possible cause is the wear of the stuffing box. Of course, this type of breakdown should be eliminated only by a professional, since most of the apparatus must be disassembled, and working with gas is extremely dangerous to the point that the gas column may explode. The repair procedure will be described below.

In order to remove the gas and water unit, you will need a 19 key. Disconnect the heat exchanger from the unit, then disconnect the ignition electrodes, unscrew the screws with which it is attached to the rear wall.

There is a stem inside, glands (small rubber seals) are put on it, if you smell gas, then it is leaking. It is likely that the oil seals have deteriorated and needs to be replaced.

The second reason is leaks in the gas pipe fittings. To check, you will need to make a soapy solution and process all connections. If you find a leak, replace the gaskets or tighten the union nuts tighter.
