Malfunctions of geysers Oasis

Let's look at the main problems that you may encounter during the operation of Oasis geysers:

1. The Oasis geyser does not turn on. Usually the cause of this problem is that the battery is dead (if the system operates with electronic ignition). To solve the problem, you simply need to replace the old battery with a new one.
2. Poor heating efficiency. Most likely the water unit is damaged. Over time, the membrane stretches and stops responding to changes in pressure levels. This leads to the fact that the valve does not open completely or does not move at all. This usually occurs due to salt accumulation, system contamination, or cracking. To solve the problem, you need to clean the water pressure unit and check whether the membrane itself is damaged.
3. The gas burner lights up and goes out. Many users note that during long-term use of the device, they often have to deal with the fact that the gas water heater goes out a few seconds after being turned on. This happens due to contamination of the ventilation system. More modern models include a screen on which error codes are displayed. Using these codes, you can determine the exact cause and breakdown of the device. However, in any case, before cleaning the chimney, it is necessary to turn off the gas supply.
4. Smell of gas. Such problems are considered serious and even dangerous. As soon as you smell any gas or burning smell, immediately turn off the gas. Contact a repairman, as most likely the oil seal is worn out and needs to be replaced.
5. Water leak. This problem is related to the heat exchanger; its integrity is compromised. The damaged element must be repaired or replaced with a new one. For example, you can use a soldering iron, and to protect the area where soldering will be done, you can use an aspirin tablet, which will prevent the oxidative process.
6. The appearance of scale. Scale forms even on special coatings. Due to deposits, the intensity of water heating decreases. In order to get rid of formations, it is necessary to use a special substance in the form of anti-scale. This option is the simplest and most affordable.

To summarize all of the above, it is worth saying that the service life of the Oasis gas water heater depends on whether the device was connected correctly, on its use and how accurately the manufacturer’s recommendations and requirements are followed.

Features of using the device

So, in order for the Oasis geyser, the operating instructions for which are included with the product, to work effectively, you must follow certain rules for using the device:

• Use only the type of gas specified in the technical recommendations;
• It is necessary to monitor the charge of the batteries on which the device operates;
• If you want to turn off the device, you must first turn off the water;
• If you are going to use the equipment for the first time, you need to take into account that there may be air in the gas supply tubes, so the device may not ignite right away;
• Setting the degree of water heating must be done by turning the tap handle or gas regulator on the body of the device;
• If you are going to turn off the device for a long time, you must first turn off the hot water tap and gas shut-off valve.

Now let's look at what you should not do when using equipment such as the Oasis geyser:

1. You cannot turn on the device if there is no draft in the chimney.
2. Do not leave the device unattended for a long time.
3. There is no need to purchase and install damaged or defective models.
4. Do not disassemble the device without permission, do not repair it, or touch it during operation.

Typical breakdowns and how to fix them

Repairing a gas water heater is an activity for highly qualified specialists. However, some breakdowns can be fixed with your own hands. Before starting work, you need to close the water and gas supply taps. After this, you need to unscrew the mounting screws and remove the handles and speaker housing.

Here are some examples of when a gas water heater won't light up:

Water heaters with automatic ignition systems may run out of batteries. All you need to do is replace the batteries. For water heaters that have a built-in generator, the piezoelectric element, electrode or power cable may malfunction. It is necessary to clean the contacts of the automatic ignition system, check the electrodes and wires for malfunctions. If all these steps do not help, you need to check and replace the power button and the piezoelectric element. If there is no draft, you need to clean the ventilation; to do this, you should call a specialist. If the pressure is insufficient, you should pay attention to the water supply or heater assembly. All that is needed is cleaning the pipes, washing or replacing filters. If the gas water heater does not turn on, you should check and, if necessary, replace the membrane of the water unit. To do this, remove the water-gas unit and, by unscrewing the screws, separate its water part

Before removing the rubber plate, it is important to remember its location. Then you need to clean the inside of the lid and install a new rubber part on the plate with the stem

It is better to replace the membrane with silicone, which lasts longer. Finally, you can tighten the screws (preferably diagonally). Some gas devices have a knob for adjusting the water flow. If the column does not light up, you need to check how the mechanical switch is located. If the pressure is not large enough and the column does not start, you should set the knob to the leftmost position and switch to the right until the device turns on. You need to adjust the jet at startup.

Self-repair of gas boilers

Before you start repairing a gas boiler yourself, you need to identify the cause of the breakdown. Various elements of heating equipment can fail. Most often, the causes of breakdowns are: violation of operating requirements, poor quality of parts, impacts.

Volatile boilers often fail due to reset. Therefore, repair of a heating unit must begin with checking the settings and the presence of open contacts. When troubleshooting, the device is turned on at full power in the “Winter” mode. Repair of heating gas boilers begins with this step.

Repairing gas heating on your own is not always possible, and only if the faults are simple and noticeable. Only specialists can handle complex breakdowns

Also, we should not forget that gas boilers are dangerous equipment, so you need to handle them carefully, and under no circumstances try to repair the gas pipe and safety elements yourself

Video about repairing a gas boiler with your own hands:

An indispensable attribute of any heating system is a boiler, which acts as a heat generator for heating the home.

The modern heating equipment market is saturated with a very wide range of boiler units of various types. But a special place in this range is occupied by gas boilers, which are becoming more and more popular every day.

This trend is due to the fact that units of this type are very effective and economical devices for heating a country house or even an apartment. In order for a gas boiler to function smoothly and stably, it is necessary to properly care for it.

One type of such maintenance is cleaning the gas boiler from soot and other contaminants. Let's talk in more detail about why to clean a gas unit, as well as in what ways this can be done.

How to choose a storage type gas boiler

There are several dozen different models of boilers on the gas water heating equipment market.

When choosing, experts recommend paying attention to several technical characteristics:

• Tank type - how to correctly calculate the volume of a storage tank is explained below. In addition to calculations, you need to decide on the choice of tank material. Manufacturers make tanks from the following types of metal:
  Stainless steel is the optimal material, characterized by long-term operation and corrosion resistance. The only drawback: high cost. Stainless steel has several classes. Only special food-grade stainless steel can be used for the storage device.
• With an enameled tank - there are several types of coating. Previously, the boiler tank was protected using ordinary enamel, which was used to cover dishes. Cheap water heater models still use this type of protection. Disadvantages: susceptibility to mechanical damage and thermal effects. The service life, even with careful use, does not exceed 5 years. Glass-ceramic coating is a modified enamel with good strength characteristics and heat resistance. Glass ceramics have a longer service life, up to 7-8 years of service.
• With titanium coating - the characteristics of boilers are similar to those made of stainless steel. The tank of a capacitive boiler will work freely for at least 10 years, and the durability is not affected by the intensity of water heating (as is the case with a conventional enamel coating).
• Burner type - there are conventional atmospheric and closed burner devices, with forced oxygen supply into the chamber. When choosing, they are guided by the technical conditions of the room used for installation. There are several types of storage tanks:
  Atmospheric gas boilers - they take air from the boiler room using natural circulation.
• Turbocharged storage water heaters with a closed combustion chamber - oxygen is supplied from the street (models with a coaxial chimney) or from the room, in a forced manner. Turbo boilers are economical. Disadvantages: noisy when turned on, volatile.
• Ignition type - not all water heaters work the same. Based on the inclusion principle, there are two main types of drives:
  Automatic ignition - runs on batteries or mains. Switching on occurs when the water temperature drops below the specified parameters. Water heaters with an electronic ignition system operate in fully automatic mode. The consumer is only required to set the heating temperature.
• Piezo ignition - in this case, a constantly working wick is provided inside the water heater. Ignition is done manually. The igniter flame is ignited by a piezoelectric element. The wick works continuously and lights the main burner.
• Fuel type - tank-type boilers operate on propane (bottled gas) and methane (from the central line). There are universal models. The latter can be easily converted to alternative fuel after changing the injectors and switching the mode. Water heaters with the ability to operate from a cylinder can be connected to a gas tank.
• Installation principle - the drives are designed in two solutions. The first ones are intended for floor installation. The volume of storage capacity is practically unlimited. Water heaters for wall mounting are limited in volume. The maximum capacity usually does not exceed 100 liters.

After selecting a storage tank according to the 5 criteria described above, we proceed to calculating the volume of the storage water heater. You can do the calculations yourself.

How to install and configure?

Thanks to the clear and simple installation diagram, placement and connection of the device to the water supply system can be done independently. However, all work related to gas communications and column adjustment can only be performed by a specialist. Before proceeding with installation, you must obtain permission from the gas service and undergo training. One of the most important conditions for installing gas equipment is the size of the room and the presence of ventilation or a chimney. In rooms whose volume is less than 8 m3, the installation of any gas appliances is prohibited.

Do not place the column above a gas stove or other sources of open fire. The wall on which the device is planned to be installed must be fireproof, made of material that does not support combustion. When installing yourself, special attention should be paid to the tightness of the fasteners and carefully check the quality of the connections after installation. Equipment setup is also carried out by gas service specialists, testing all modes and functions of the device.

Starting the device and adjusting the temperature

To correctly set up hot water in the device, you must:

• Open the hot water mixer fully;
• Using the water switch, select the required temperature value;
• Close the tap.

According to the advice of professionals:

• Wait for the moment when the pressure in the line drops, but the column will still work;
• Turn the water toggle handle to the maximum;
• Turn the gas regulator to the minimum value until the temperature is as desired.

For final preparation, it is worth adjusting the gas supply. To do this, you need to look at the technical data sheet and find out the minimum value for this brand.

The toggle switch is turned to the minimum value.

Turn on the gas supply valve. At the gas water heater, Electrolux and Ariston do this after connecting to the network. The Oasis, Junkers and Bosch gas water heaters are connected when the batteries are installed.

The hot valve is turned on and the device starts working.

How to adjust the water temperature

Turn on the mixer and check the water heating temperature. It must be twenty-five degrees more than the original one. It is worth noting that the water in a gas boiler heats up gradually. The geyser is adjusted using the gas lever.

Professionals do not recommend heating water above fifty-five degrees. This has a bad effect on the device, as scale forms.

Blood pressure problems

Setting up a geyser requires some time. Accordingly, the result will be visible later. After each stage, it is worth pouring out the water and letting it heat up again so that the values ​​are correct. Low pressure in the device may interfere with normal operation.

If you have problems with blood pressure, you should perform the following manipulations:

• Remove the casing from the device;
• Loosen the locking bolt, use a pressure gauge to check;
• Remove the seal from the adjusting screw;
• Turn on the boiler;
• Set the values ​​to maximum, unscrew the hot water supply taps;
• Adjust the desired pressure.

The Bosch gas water heater, namely its pressure in the nozzles, is regulated in the following way:

• Remove the casing;
• Attach a pressure gauge;
• Loosen the locking screw;
• Attach a pressure gauge to check the pressure in the injectors to the nozzle.

Next, the Bosch gas water heater with maximum thermal power is regulated:

• Remove the seal from the screw;
• Turn on the device;
• Hot water taps are turned on;
• The adjusting screw adjusts the pressure in the nozzles;
• Put the seal in place.

There are brands that have a special “Winter-Summer” mode with temperature adjustment. This handle was made at the bottom of the Ariston gas water heater. Adjustment of the Oasis gas water heater is located on the front panel. The peculiarity of the mode is that in winter the power is higher than in summer. The heating power of the liquid in the column is directly related to the temperature of the inlet stream. In winter, the regulator is set to “maximum”, the heating will be at its highest. In summer, the temperature of the inlet flow is higher and is set to the minimum position. This saves resources.

It is easy to remove bad pressure when checking.

To do this, you must perform the following manipulations if the device has already been used:

Pay attention to the rubber membrane. The performance of this part is directly related to the pressure in the line

At the moment the integrity of the membrane is broken, namely when it is exhausted, gas does not flow and the burner does not turn on. The problem is solved by replacing the part. Pay attention to the mesh filter. It is located at the entrance to the water block. The water pressure becomes lower due to debris clogging the part. The problem is solved by cleaning.

If scale has formed in the heat exchanger.

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

To remove scale, you can use special liquids that are sold in the store. There are also devices that can be used for cleaning. The mechanism of action of the devices is simple; the device itself is a kind of reservoir with a built-in pump for extracting water. The tubes of the cleaning device are connected to the radiator tubes of the geyser. The cleaning reagent is heated and pumped into the heat exchanger; it does not need to be removed from the column. The plaque gradually begins to dissolve in the reagent. However, they have a fairly high cost.

You can also carry out cleaning in a more economical way with your own hands, without the use of automatic means. You need to remove the radiator and remove all water from it. Cleaning is done using a purchased 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, and the heat exchanger pipe is filled with the prepared liquid. It is necessary to pour into the pipe from the end of the lower turn 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 pipe of the heat exchanger, attach the hose, and lower the other end into a sink or other container. Open the water tap; the flowing water will displace the existing solution along with the scale. If necessary, repeat the procedure again.

Oasis geyser device (with diagram)

The internal part of standard hot water gas equipment is presented:

• plate heat exchanger with a water tube;
• gas burners;
• exhaust gas collector;
• piezoelectric element or automatic electric ignition.

The electronics are powered through batteries, from the mains, or using a miniature built-in turbogenerator. The water temperature control in budget models is carried out by a water reducer or so-called frog, and in more complex and modern models - automatically via electronics.

Gas boilers are characterized by the presence of an open or closed combustion chamber, and the difference between models of the first type is represented by the intake of air masses directly from the room.

Exhaust gases are removed naturally through a chimney system, or using forced ventilation and a coaxial chimney.

The components and main components of flow-through gas equipment that require competent maintenance and explain the principle of operation are listed in the diagram.

Modern gas water heating equipment Oasis is equipped with protective automatic gas supply shutoff

Modern water heating equipment is characterized by the presence of protective automation, represented by flame control and a traction sensor, which allows you to shut off the gas supply automatically.

How to connect and configure

Gas water heating equipment is installed in the kitchen or any other non-residential but heated room in accordance with the gasification project and in accordance with the basic requirements of gas supply organizations:

• water heating equipment is connected to a chimney system that has good and stable draft;
• It is prohibited to install equipment above any open flame sources or heating devices;
• before installation, permission from gas service specialists to install equipment must be obtained;
• installation of the unit is carried out by the operating organization of the gas industry or other licensed companies;
• installation is carried out on non-flammable coatings, including brick, concrete and ceramic tiles with mandatory insulation with galvanized sheets and BTK;
• the protective layer of insulation should protrude beyond the body by at least 10 cm along the entire perimeter;
• the column is suspended using brackets attached to the wall, supplied with the gas equipment;
• all shut-off valves in the form of water supply to the gas supply to the unit are located in an easily accessible place;
• a filter system is installed in front of the water heating equipment to purify the water supplied for heating;
• to connect to the water supply, pipes or flexible hoses are used with an internal diameter of 13–14 mm or more.

Below is a standard connection diagram for a gas boiler.

Connected gas equipment must be registered

After installation and until it is put into operation, the water heater must be registered with the gas service.

Standards for installation and connection of the Mora column

The basic requirements are listed in the technical data sheet of the device and the operating manual. Violations made during installation lead to refusal of warranty service for the boiler. Requirements:

• The connection must be carried out by qualified specialists with the appropriate license and work permit. After installation, a report is drawn up (the form is in the device passport) and a stamp is placed indicating that the water heater is put into operation.
• A coarse filter is installed on the supply pipeline; in some cases, at low pressure, a booster pump is connected.
• The column must not be installed in rooms with high humidity (bathroom, toilet), directly above a gas stove or refrigerator.
• The room used for the boiler room must comply with the standards described in SP and SNiP.

Maintenance of Mora Top geysers should be carried out at intervals of at least 1-2 years. Independent or unqualified repairs lead to removal of the water heater from the warranty, which lasts 3 years from the date of commissioning. Repairing a Mora gas water heater with your own hands will inevitably lead to a refusal of free service. If a breakdown occurs after the warranty expires, call a gas technician. It is better not to try to repair the water heater yourself.

Common breakdowns and troubleshooting of the Mora gas water heater:

• The main burner does not turn on - the reason is dead batteries, poor water pressure, lack of sufficient oxygen in the room.
• Presence of a leak - the rubber membrane of the water reducer has broken, corrosion has corroded the heat exchanger (a copper coil is installed on the Mohr column, there will be a green coating in the place of leaks).

For supplying hot water and heating a private home, the most popular equipment is a gas water heater. It is available to almost everyone and does not require large expenses. But it is necessary to choose quality equipment. After all, a comfortable atmosphere in the house and safety depend on this. In this article we will consider all the advantages and disadvantages, as well as the features of the Mohr gas water heater.

Popular models for apartments and country houses

A review of efficient Oasis instantaneous water heaters with an affordable price will help you make the best choice for arranging comfortable living in city apartments and the private sector.

Model “Glass 20VG”

Glass 20VG has a low cost, energy-saving function, an anti-freeze system and sufficient performance to supply hot water to two points. Disadvantage: battery operation and the need for a chimney.

The TUR 24 consumes a little more power, but has forced ventilation, an electrical connection and greater performance, which makes this model more affordable. Installation and connection methods

Installing a gas water heater for the first time or when replacing a faulty one that has failed requires various preparatory operations.

When installing a gas device, the project must be agreed upon and the gas wiring to the installation site of the column must be correctly completed. The document indicates the characteristics of the room, installation location, and type of device. It is better to entrust these works only to specialized organizations licensed for this type of activity. The connection is made in accordance with the instructions and SNiP.

Before connecting, turn off the gas. Using a gas wrench, unscrew the hose nut. It is difficult to damage a flexible connection using a hose, but if the connection was made using metal pipes, it will have to be dismantled by sawing. It is better to replace old hoses.

Then turn off the cold water supply. Begin installing the water heater according to the attached diagram. The distance from the outlet of the exhaust gas column to the chimney must be at least 50 cm, but in rooms with a height of 2.70 m, installation with a height of 25 cm is allowed.

At the next stage, connect the water supply, connecting to the input and output of the column. Modern flexible hoses allow you to avoid leaks by tightening the fixing nuts. When using pipes, it is necessary to eliminate leaks with tow or FUM (tape sealant).

Then connect the gas. It is better to use the services of a specialist.

Mixing cold water in the mixer

Many people, instead of adjusting the degree of heating on the gas water heater itself, mercilessly torment the mixer. If you open the cold water too much, the lit column will simply go out. If at that moment it was not burning, then it will certainly not catch fire. Make it a rule to turn on the hot water supply first, and only then the cold water supply. It’s best to adjust the degree of heating using the appropriate controls.

You also need to remember that intensive mixing of cold water is not welcomed by the developers of geysers - this can lead to their damage.

User opinions

“We installed an Oasis turbocharged gas water heater in the apartment two years ago, the model functions without leaks or malfunctions. It turns on when the tap is opened, even with low water pressure, heating takes no more than 10 seconds, and serves two points: in the kitchen and in the shower. It works directly from a regular power supply, there is no need to purchase batteries, however, it does not start when the lights are turned off. Like all gas water heaters, it is economical, fuel consumption is insignificant, combustion products are removed forcibly, and the noise is quite tolerable. The disadvantages include a sharp increase in water temperature when opening the second tap, albeit short-term.”

Igor, Yekaterinburg.

“I have been using the Oasis electric boiler with a capacity of 50 liters for more than a year, I consider its quality and reliability to be fully consistent with the price, there have been no reasons to contact the Oasis for repair or warranty service. The insulated tank of the storage water heater holds heat well; the amount of water dispensed is quite enough for two people. I consider the only inconvenience that it takes a long time to heat up an empty tank - from 1 hour, I noticed that it is better to leave some of the hot water, so it reaches the desired temperature faster.”

Alexander, Rostov-on-Don.

“I live in a private house, there was a need to replace the column, the old one could not be repaired. I chose a gas water heater from the manufacturer Oasis, did the installation myself, and the standard diameter of the chimney was suitable. I would like to note such a feature of operation as the need for good traction; one day the pipe became clogged with debris and the equipment simply did not turn on. Also, for private homes, I advise you to buy the Oasis model with frost protection and a “winter-summer” mode; gas consumption is actually reduced by 50% in the warm season.”

Grigory, Chelyabinsk.

“I purchased an Oasis instantaneous water heater with automatic ignition for my dacha with the simplest functions and protection. The purchase was justified, there was no need for expensive repairs, the only malfunction during the three years of service was the ignition button. To preserve the resource, I advise you to drain the water from the heat exchanger in case of rare visits in winter, even with good insulation of the chimney.”

Eduard, Nizhny Novgorod.

“We bought an Oasis brand water heater with a 30-liter storage tank a year and a half ago, based on positive reviews and an affordable price. The boiler pays for itself, but when guests arrive, the water runs out too quickly; I think that for a large family it is better to purchase a more capacitive model. In automatic mode, the temperature inside the tank is maintained for up to 4 hours without consuming electricity.”

Irina, Moscow.

“I decided to buy an Oasis for an apartment with a family of 4 people, since it was not possible to install a groove. I spent a long time studying reviews of household appliances and settled on the Oasis Slim with an 80-liter tank; its performance turned out to be sufficient. I can’t call this option economical, but it covers the need for hot water. There are no complaints about the reliability of the boiler; I don’t see any external corrosion or leaks.”

Sergey, Ekaterinburg.

Oasis instantaneous water heaters

Gas instantaneous water heater Oasis SG-20

The instantaneous type of water heaters has become widespread. The key feature of this model is that water will be heated even at low pressure in the water supply system.

According to user reviews, the Oasis instantaneous gas water heater has a number of advantages:

1. The device turns on only when the water is turned on. This helps save energy resources.
2. Functions regardless of electricity, because its operation is carried out using replaceable batteries.
3. Depending on the season, you can choose the heating mode.
4. The device is designed according to a special design that helps reduce costs.

I smell gas from the dispenser, what should I do?

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

There is a rod inside, with seals (small rubber seals) put on it; if you smell gas, it means it is leaking. It is likely that the seals have deteriorated and need to be replaced.

The second reason is a leak in the connecting elements of gas pipes. To check, you will need to make a soap solution and treat all connections. If you find a leak, replace the gaskets or tighten the connecting nuts tighter.

Troubleshooting that prevents the gas heater from igniting

There is a turbocharged gas water heater with electric ignition. When the hot water is turned on, the heater clicks, but does not light up. An electric discharge is heard and the fan turns on.

The first step is to carry out an inspection; to do this, remove the column cover. It is fastened with four bolts: two from below, two from above. We also remove the knobs for adjusting the flame, temperature, and winter-summer mode. Upon inspection, everything seems intact, the wires are not burned anywhere, water is not leaking anywhere.

The principle of operation is that when a water flow appears, the gas valve is activated, an electric discharge is created, the gas is ignited, and at the same time the fan is turned on to draw waste combustion products outside. If the water pressure is insufficient or the hood does not work, the gas goes out and the column turns off.

So, open the tap and see what happens. Water rustled through the heat exchanger tubes, the electrodes gave a discharge, the fan turned on, but the gas did not ignite. Let's check if the relay (microswitch) is working, which is activated when there is sufficient water pressure and opens the gas supply valve. To do this, turn the tap again, the relay tongue should move away.

It works, which means the pressure is sufficient for the gas water heater to operate. Now let's check the operation of the gas valve. To do this, use a screwdriver to move the same tongue away without opening the water. If there is a spark at the electrodes and the fan starts working, then the gas valve is working.

The fault was found quite quickly; the ignition electrode did not produce a spark. There are only two of them: extreme ones. The one in the center is the control one; if there is no flame, it turns off the gas supply.

Other device problems

In addition to error codes, there are other malfunctions that are also typical for the Neva Transit gas water heater:

1. The appliance is too noisy. In this case, you should start turning the water regulator and reduce the pressure.
2. The gaskets “stick out” in the pipe connection areas. The problem is solved by replacing the element.
3. The display has stopped working. The problem lies in faulty contacts, a broken display and a faulty temperature sensor. The solution is to replace the parts and the display itself.
4. The device stopped lighting up. This problem is also typical for the Zanussi gas water heater. The malfunction lies in membrane stretching, overheating and a broken device element. Solved by replacing the part with a new one.

When repairing with your own hands, it will take a long time to study the repair material and actually set up the gas water heater. The result the first time may not be the same as in the repair instructions in the literature and may even be disastrous. The best option would be to entrust the matter to professionals.

The speaker turns off during operation

The device turns on, operates for a long period, then turns off. Why the speaker may go out during operation:

• Settings are checked. Probably, automatic shutdown after a certain period was selected.
• Increase in temperature indicators - more than 100 degrees. In this case, the temperature sensor will work and the operation will stop.
• Insufficient pressure in the gas or water supply.
• The contact between the thermocouple and the magnetic valve is broken. Contacts are cleaned and connections are tightened.
• Oxidation of contacts of the control unit. The device begins to click, but the wick does not light. The contacts need to be cleaned.
• The batteries are low. Replaced every 6 months. It is optimal to purchase batteries with a high charge content.

Clogged shower head and hose

It happens that the speaker turns on and immediately goes out when switching to the shower. This is associated with clogging of the watering can. It is necessary to unscrew it, clean it and wash the holes. It is effective to soak metal elements in a solution with citric acid.

Scale on the watering can is formed due to an increase in water hardness in a number of regions. For these purposes, filters are installed or a mixer with a shower is purchased, which is equipped with an integrated anti-scale system.

The next part that sometimes causes the wick to go out is the shower hose. When it gets tangled or clogged, the pressure decreases and the device turns off.

Sometimes the mixer breaks or becomes clogged. It is necessary to disassemble it, check it, and clean it if necessary.

Soot accumulation on the heat exchanger

During operation, the heat exchanger accumulates soot and scale. If it becomes clogged, the color of the fire will change to blue. Cleaning algorithm:

• The casing is removed.
• The screws are unscrewed.
• The water supply is cut off.
• The faucet opens to drain hot water.
• The thread and tap are disconnected.
• A solution of hydrochloric acid is prepared.
• Take a pipe with a diameter of 1/2″ inch or use a hose.
• One end is connected to the input, the other to the output.
• The solution is poured into the funnel.
• When pressure appears at the outlet, the procedure stops.

When working, you must wear gloves. When the scale has been removed, it is necessary to thoroughly flush the heat exchanger to remove acid. Cleaning is recommended once a year. Regular care helps the device function properly.

Traction is poor or completely absent

The accumulation of combustion products is often associated with clogging of the chimney with scale and dirt. If there is no traction or it is not enough, the working out will not be removed.

To check the traction, you need to bring a lit match or lighter to the control window of the device. If the fire deviates to the side, draft is present. If it remains lit, it is missing.

It is necessary to take into account that the fire sometimes goes out due to external circumstances - gusts of wind, for example. The draft in the mine will increase or decrease under the influence of drafts.

The chimney is also cleaned through a “pocket”, which is located 0.25 m lower. When such actions do not help, you need to call specialists.

Causes of problems and DIY repairs

The use of geysers, however, like any other equipment, is accompanied by malfunctions, frequent or rare. At the same time, there are some malfunctions that can only be eliminated by specialists who have the necessary knowledge and permission to do so. But there are also some that can be easily eliminated with your own hands, so we will consider them.

1. The most “popular” type of failure is that it simply does not turn on. If it has an electronic 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 purchase, since the batteries last only that long.
2. Also, when using a gas water heater, it may happen that the water in it does not warm up or warms up, but not well enough. Often the cause of such problems is the water node, or more precisely, its defect. As a result, the membrane stops responding to changes in pressure 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 must know at least in general terms the structure of the geyser, because the defect can be of several types. If salt deposits have accumulated.
3. If the system is clogged.
4. If cracks have formed, etc.

To fix this problem, you must first disconnect the column from the gas supply, then clean the water unit and check the membrane.

If the internal elements of the device are covered with soot or dirt, 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 water heater has stopped working correctly may be that the burner goes out immediately after turning on. This happens because the ventilation duct is clogged. Modern models of geysers are equipped with special sensors for such cases, which will inform the owner if there is no draft. After this, the gas supply should be turned off immediately. Next, the chimney should be checked. To do this, the plug is dismantled and everything that has accumulated there is removed.

Important! You can check the draft of a chimney in the old “old-fashioned” way: bring a lit match to it. If the fire on the match deviates in the direction of the chimney, then everything is fine with it

If this does not happen, then it needs 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.
