Repair of the Oasis geyser: overview of typical breakdowns and recommendations for their elimination

Malfunctions happen in any equipment, regardless of the manufacturer. Be it a famous German brand or its Chinese equivalent. The difference is that in the second one they occur more often.

The breakdown of such an irreplaceable device as a geyser creates a lot of inconvenience. If the malfunction is not related to a gas leak, in most cases, you can repair the Oasis geyser yourself. We will talk in detail about what kind of breakdowns are most often diagnosed in speakers of this popular brand among users, as well as how to fix them in this publication.

Geyser oasis setting

Many users encounter a problem: the column does not produce the expected results. This happens due to incorrect equipment settings. Manufacturers found a way out and released devices with automatic adjustment. We will tell you how to set up a gas water heater - regular and automatic.

Preparatory work

Despite the fact that each column “Selena”, “Vector”, “Bosch”, “Neva” comes with instructions indicating the settings, not all users understand them. One mistake at the beginning - and the technology does not function as it should.

Work begins with adjusting the water. If you do not do this right away, then all settings will be inaccurate. The flow should be minimal. The nominal values ​​are indicated in the documents, but they are general: 6, 10, 12 liters.

How to set the hot water regulator:

• Open the hot mixer to full power. When connecting to several intake points, only one valve can be unscrewed.
• Using the water switch, set the desired value.
• Turn on the tap.

Follow the recommendations of experts:

• Wait until the pressure in the line decreases, but the column will still turn on.
• Turn the water toggle knob to the maximum position.
• Turn the gas regulator to the minimum mark until the temperature suits you.

To finish cooking, you need to adjust the gas supply. Check the data sheet again to find out the minimum value for your model.

• Turn the toggle switch to minimum.
• Open the gas valve. In the Ariston and Electrolux models, this must be done after connecting to the network. In Oasis, Dion, Bosch, Junkers heaters - after installing batteries.
• Open the hot valve and the column will start working.

Adjusting the water temperature

Open the mixer and evaluate the heating temperature of the water flow. It should be 25 degrees higher than at the entrance. Keep in mind that the gas boiler does not heat the water immediately, you need to wait a little. Use the gas lever to adjust.

You can also adjust the temperature using a water toggle switch. By increasing the flow force, you reduce the heating temperature, and vice versa.

Experts do not recommend heating above 55 degrees. This negatively affects the operation of the device, since scale is actively deposited.

The settings take some time, so you don’t need to wait for the results right away. After each stage, you need to drain the water and let it heat up again to check the accuracy of the indicators. Operation may be hampered by reduced pressure in the system.

If the device runs on liquefied gas and there are problems with pressure, do this:

• Remove the device casing.
• Loosen the locking bolt and measure the readings with a pressure gauge.
• Remove the seal from the adjustment screw.
• Start the boiler.
• Set the maximum values, unscrew all hot water faucets.
• Set the required pressure.

Some models are equipped with an additional “Winter-Summer” mode. The heating power of the water in the column depends on the temperature of the inlet flow. In winter, the regulator is set to the “maximum” position - maximum heating. In summer, the inlet temperature is higher, so the value is “minimum”. This saves resources.

Problems with poor water pressure can be corrected by checking. If the equipment has already been in operation and you decide to reconfigure it, but there is no pressure:

• Check the rubber membrane. Its operation depends on the pressure in the line. The membrane bends and the gas valve is activated. When it wears out or becomes deformed, the gas supply does not start and the burner does not light up. Replace the membrane.
• Mesh filter. Located at the entrance to the water reducer (block). It becomes clogged with small debris from the water supply, so the pressure may decrease. Clean the part.

Setting up an automatic column

Such devices are equipped with only one regulator. It is responsible for power and heating temperature. The built-in self-diagnosis system conducts a complete assessment of the operation of the units upon startup. If something is wrong, a red indicator on the panel lights up - the equipment is blocked from turning on. In this case, you need to adjust the pressure as described above.

• Remove the batteries from the compartment.
• Turn off the microswitch.
• Insert batteries.
• Open the hot water tap and turn on the microswitch.
• Set the burner pressure to maximum.
• When the settings are saved, the orange light will light up.

The lineup

The company's product range is quite wide. Classic, chimneyless and turbocharged models, varying in their power, operating principle and appearance, are presented to consumers. The most popular are the mid-price columns, which provide an uninterrupted supply of hot water for very little money. Among them there are a number of models, the customer reviews of which are most common.

“Oasis Glass 20 VG” is a flow-through device that requires a chimney and has a unique design. Thanks to its small dimensions of 34x59x14.5 cm, the speaker fits harmoniously into small rooms, does not clutter up the space and does not spoil the interior. The model is powered by batteries, which ensures complete energy independence of the unit and makes its operation independent of power outages. The dispenser starts automatically immediately after opening the hot water tap at a pressure in the water supply pipes of at least 0.02 mPa. The dispenser is equipped with an RCD, thermostat and anti-freeze function, and the presence of the “Winter-Summer” mode allows you to save up to 70 cubic meters of gas per year. The model’s productivity is 10 l/min, which with an optimal power of 20 kW is quite enough for the bathroom and kitchen. The efficiency of the device is 90%, and the cost varies from 4 to 4.8 thousand rubles.

“Oasis TUR-24” is a device from the “Turbo” series that operates from an electrical network and does not require regular battery replacement. The gas burner is ignited synchronously with the opening of the tap. The model does not require the installation of a chimney: combustion products are removed forcibly using an electric fan built into the housing. Exhaust gases are discharged to the street through a corrugated pipe.

Column productivity is 12 l/min. The turbocharged model is equipped with a liquid crystal display that allows you to monitor the temperature and overheat protection that automatically turns off the device if the permissible temperature is exceeded. The dimensions of the column are 33x62x18.5 cm, the cost is 9 thousand rubles.

“Oasis B-12W” is a miniature flow-through chimneyless model with dimensions of 29x37x12 cm and a capacity of 5 l/min. It is usually installed on one of the intake points, which is due to its fairly low power, not exceeding 11 kW. Ignition is carried out using replaceable batteries. The device is equipped with a copper heat exchanger, overheating protection and a display. The cost of the column is 4 thousand rubles.

"Oasis 20-OG" is an economical, energy-independent device designed to operate on liquefied gas from cylinders and used in homes that are not connected to central networks. The model is equipped with a “Winter-Summer” function, gas control, thermometer and ionization sensor. The heater's productivity is 10 l/min, power is 20 kW, and the cost does not exceed 5 thousand rubles.

How to set up and adjust a gas water heater

Excessively hot water, high gas consumption - all this is a consequence of the fact that the settings and adjustments of the gas water heater were performed incorrectly. Meanwhile, you don’t need to be a specialist to select an operating mode that will provide comfortable operating conditions for a flow-through gas boiler.

The settings of Chinese, Russian or European speakers are not much different from each other, so below are the general principles for making adjustments taking into account the type of boiler (automatic or semi-automatic).

How to adjust water in a gas water heater

Not every boiler has a DHW control function. If we talk about automatic water heaters, changing the water flow is done using a rotary knob located on the front side of the casing. In semi-automatic machines, such a function is provided only in modern models.

In old geysers, in order to regulate the temperature of hot water, it was necessary to regulate the intensity of gas combustion. The intensity of the flow was changed by means of two bolts on the back side of the water reducer, which could only be reached by disassembling the boiler body.

Methods for regulating temperature in instantaneous gas water heaters by changing the water speed:

• Mechanical control unit - there are two rotating knobs on the body. As a rule, the left one is responsible for the gas supplied to the burner, the right one for the speed of water flow when the hot water tap is opened. Using the latter, the heating temperature and the minimum threshold for the burner operation are set. The lower the flow rate, the more the water heats up.
• Columns with electronic control of outlet temperature - settings in this case simply require selecting the appropriate mode. The boilers have a modulating burner that automatically maintains the specified heating intensity. Setting up an automatic instantaneous gas water heater and correcting errors and failures is carried out exclusively by a specialist.

User manual

Before turning on the gas water heater and starting to use it, you must carefully read the rules for using the device and safety precautions:

• When operating gas equipment, you should use only the type of gas recommended by the manufacturer.
• When turning on the device for the first time, remember that air may accumulate in the pipes, which is why the burner may not ignite immediately. Therefore, ignition should be done twice with a short interval between attempts.
• Setting the heating parameters is carried out by turning the regulator located on the body of the device. When switching on for the first time, set the lever to the minimum value and perform a test heating. Once it becomes clear that the device is working correctly, you can begin testing different temperature conditions in increasing increments.
• In the process of further use, you should not forget to change the electric ignition batteries on time and periodically clean the column from scale, carbon deposits and dust.
• If there is no draft in the chimney, the device cannot be turned on.
• Unlike gas boilers with a closed combustion chamber, the column cannot be left unattended for a long time. This is dictated by fire safety rules and the design features of open-type burners.
• Unauthorized disassembly of the device and installation of third-party spare parts is prohibited. Only a service center technician or a gas service specialist can repair dispensers.

Malfunctions of the gas water heater Oasis

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

Internal organization

The diagram above shows the design of a typical gas water heater, which is also typical for Oasis columns.

Let's look further at how the most common type of brand's flow-through chimney model with automatic ignition works.

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

Next, the water passes through a coil rigidly fixed to a heat exchanger, which is heated by burning gas. The coil transfers heat to the flowing water coming out.

When the tap closes, the water-gas unit turns off the gas supply. The combustion stops and the column goes into standby mode for the water tap to open.

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

Maintaining the required temperature regime is an equally important condition for fire safety and long service life of the column.

Peculiarities

High consumer demand and popularity of Oasis geysers are due to a number of undeniable advantages of these devices:

• The high safety of using the units is explained by the presence of protective sensors that turn off the device in emergency situations.
• The ability to provide stable heating of the coolant, regardless of pressure drops in the water supply system, makes the operation of the dispensers simple and comfortable.
• The location of the main module away from the hot water pipe increases the safety of the device and protects important structural components from overheating.
• The presence of a mesh filter protects the system of pipes and pipes from clogging and rust accumulation.
• Economical fuel consumption is due to the presence of “Winter-Summer” modes. This allows you to automatically regulate the fuel supply and significantly save on water heating.
• The presence of a heat-resistant alloy in the radiator eliminates the formation of scale on the internal walls of the device.
• High efficiency rates and long service life distinguish Oasis speakers from other devices available in this price category.

• The presence in the product line of turbocharged models capable of forcibly removing gas combustion products. They allow you to use the water heater without installing a chimney and make its operation even safer.
• The modern and aesthetic design allows you to install speakers in kitchens and bathrooms without the risk of spoiling their appearance.
• All Oasis models are equipped with a liquid crystal screen and a control panel, which makes using the device simple and convenient.

The disadvantages of geysers include the relatively quick failure of the control unit, the lack of a fire modulation function in the burner, and the high cost of some models.

Geyser: Oasis, breakdowns, reviews

• Features of using the device
• Error codes for the gas water heater "Oasis"
• Main causes of malfunction and their elimination
• How to prevent breakdown of the Oasis geyser

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

The layout of the Oasis gas water column components is typical for most models of Chinese-made flow columns

The diagram above shows the design of a typical gas water heater, which is also typical for Oasis columns. Let's look further at how the most common type of brand's flow-through chimney model with automatic ignition works.

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

Next, the water passes through a coil rigidly fixed to a heat exchanger, which is heated by burning gas. The coil transfers heat to the flowing water coming out.

When the tap closes, the water-gas unit turns off the gas supply. The combustion stops and the column goes into standby mode for the water tap to open.

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

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

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

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.

Malfunctions and methods for their elimination

Before you start troubleshooting the Oasis brand column and choosing a solution, you need to make sure that there is normal water pressure in the system and draft in the chimney.

It is better to check the draft with a candle or match; the flame should deviate well until it extinguishes.

Let's consider the most common malfunctions that appear during the operation of Oasis speakers, possible causes of their occurrence, and methods of elimination.

The flame in the burner does not ignite

If the Oasis gas water heater does not light up, there may be several main reasons.

Let's talk about the main ones:

Insufficient power supply to the speaker

Insufficient power supply or no power supply. The most likely and simplest reason for this malfunction lies in dead batteries.

If, when you open the tap, you hear a discharge crackling sound, there is a spark, the pressure is normal, but the gas does not ignite, then the reason is most likely in the batteries.

Over time they lose their capacity. Their power drops, they cannot supply the required current to the load. It is only enough to start a high-voltage generator, and there is not enough power to open the solenoid valve.

Deterioration of contacts in the battery compartment due to corrosion and contamination can also cause ignition problems. Corrosion can be caused by leaking batteries or moisture entering the contacts from the outside.

Repair instructions: replace the batteries with new ones. Alkaline elements should be installed. First you need to check the condition of the contacts. If necessary, wipe them with alcohol, or clean them with sandpaper, a knife or a file.

If corrosion damage occurs as a result of moisture ingress, the source should be identified and the leak repaired.

For chimneyless speakers, the lack of ignition may be due to a faulty power supply. Only in this case there will be no spark discharge.

Weak pressure at the water heater outlet

Deterioration of water flow through the column is a common occurrence.

If the water pressure in the system is normal, but the outlet of the column is weak, then there may be several options:

• the filter at the inlet of the water block is clogged;
• the throughput of the heat exchanger coil is impaired due to scale;
• the mesh divider (aerator) on the hot water tap is clogged;
• a piece of scale got into the flexible hose supplying hot water to the tap.

Remedy: remove, clean, rinse mesh filters under running water. Replace flexible hose. Clean the heat exchanger.

Water unit malfunction

Under the pressure of the incoming water flow, the membrane pushes the rod, which opens the mechanical gas valve and presses the microswitch button that activates the ignition.

This mechanism may fail for the following reasons:

• the membrane is worn out, over time it loses its properties, elasticity, and breaks; the rod is stuck.

Repair instructions: disassemble the water unit. If the threaded connections are stuck, treat them with anti-corrosion agent WD-40 or brake fluid and leave for half an hour.

Then replace the membrane, lubricate the rod, spring and seal. It is better to install a new silicone membrane; it will last longer.

Malfunction of microswitch or solenoid valve

You can check the serviceability of the microswitch and solenoid valve with a multimeter. To do this, it must be switched to resistance measurement mode with a minimum limit.

Connect the probes to the microswitch terminals and alternately press and release the button.

If the readings of the device vary from one ohm to infinity, then the switch is most likely working. If the readings do not change, the microswitch is faulty.

To check the solenoid valve, you need to measure the resistance of the solenoid windings at the connector terminals. It should be about 400 ohms between the black and yellow wires, and the yellow and red.

Between the red and black wires - about 7 ohms. If the measurement results are significantly different, the solenoid valve is faulty.

Gas water heater oasis how to adjust water temperature

2016-11-17 Evgeniy Fomenko

The optimality of its operation, the economical use of resources, and the longevity of its operation depend on the correct settings of the geyser. Let's consider the adjustment of devices that have two toggle switches on the front panel - water and gas regulators, the device type is semi-automatic.

Setting up any gas heater should begin with adjusting the water. The nominal value of this parameter is indicated in the technical data sheet supplied with the device, usually 6, 10, 12 liters. In order to correctly set the device to the required value, you need to open the hot water valve; it is important to comply with the condition - you should open only one tap if you have several water intake points. Using the water toggle switch, set the value corresponding to the nominal value. After setting, the tap closes.

But we must take into account the fact that the flow pressure of the main line is different for everyone and there are no general rules for setting it up.

Some experts advise that when the system pressure is weak, but the heater turns on, the water toggle switch should be set to maximum, and the gas switch should be gradually turned from minimum until a temperature that suits you is reached.

In order to adjust the gas supply to the device, you need to set the gas regulator knob on the front panel of the device to the minimum setting. After connecting to the power supply (for models such as Ariston and Electrolux), or installing batteries (Neva, Neva Transit, Selena, Ladogaz, Oasis, Junkers, Bosch Therm, etc.), you need to open the gas valve. Then you need to open the hot water tap, the water heater will turn on and start heating.

The next step is to use a temperature measuring device and set the gas regulator to such a position that the temperature difference at the inlet and outlet of the device corresponds to 25 degrees.

It should be taken into account that heating does not occur immediately; you should wait a while. During subsequent operation of the column, the temperature at the outlet of the device is changed using a hot water valve. By turning on a larger flow, it decreases, and a smaller flow increases.

Oasis geysers: design and characteristics of instantaneous water heaters

Water heating devices have become part of human life, and today it is impossible to imagine life without them. Like all appliances, the speakers become unusable over time, and the time comes to buy a new water heater. In order not to make a mistake with your choice, you should pay attention to the advice of experts.

The Oasis geyser is an instantaneous water heater that differs from its competitors in its long service life, reliability and high-quality workmanship. In addition, the entire line of gas water heaters of this brand belongs to the middle price category.

Other advantages and disadvantages, as well as the most popular models of this line of heaters will be discussed in this article.

Features of Oasis speakers

The Oasis brand, known today on the domestic market, is the brainchild of a German company. The company is focused primarily on the CIS market and is international, although it is located in Germany.

Electric ignition does not work on one burner

Most gas stoves are designed in such a way that a person does not have contact with open fire. The practicality of automatic ignition is explained by the fact that it is easy to use: all you need to do is turn on the button that is specifically designed for this. But the following problem may arise - the electric ignition does not turn on on one burner. What to do then?

If the ignition does not turn on when the button is pressed, or clicks are heard but there is no spark, it means that the device is not working properly. If all the burners are working properly and only one does not turn on, the problem may be in the high-voltage wire. It is supplied to the ignition device, and disturbances in it lead to interruptions. The cause may also be a breakdown of the ignition device or damage to the entire auto-ignition unit.

The most common cause of interruptions in the operation of one burner is contamination of the nozzle nozzle. When cooking food, food residues could get there, which interfere with the flow of gas. To fix the problem, you need to clean or replace the nozzle.

The problem of one non-working gas stove burner may be a breakdown of the gas control system. In this case, the flame flares up and goes out immediately after the button is released. The repair consists of replacing the thermocouple, electromagnetic button or the entire gas control mechanism. Its complexity depends on the degree of damage.

The gas valve on the stove may not turn properly. This is also one of the reasons for poor gas supply and poor combustion. The faucet handle becomes clogged with carbon deposits, particles of debris and dust. It should be lubricated, cleaned and turn well.

Unstable pulsating combustion

Causes - solutions

- water, air, impurities in fuel - replace fuel

- the fuel pump does not create sufficient pressure - inform the service department

— nozzle/filter clogged—clean the nozzle/filter

- the burner is not adjusted, the burner is not configured correctly - inform the service department

- incorrect installation of the chimney/flue - eliminate

— small diameter of the fuel supply line — replace the fuel line

Electric ignition is damaged on two burners

From time to time, a situation arises when two burners do not turn on using electric ignition. In this case, lighting a fire with a match gives a positive result. In this case, the breakdown is caused by the candle responsible for ignition. Repairing the device will include the following steps: the spark plug must be inspected, cleaned, and the power cord put in order. Perhaps that is where the problem lies. If the element has cracked, it must be removed and replaced with a new one.

A faulty button can also cause problems with the electric ignition of the stove. The button may become clogged with debris or dust and suffer mechanical damage. To correct interference in the operation of the equipment, the button is replaced or, if possible, cleaned of dust and oxidation.

Ignition produces a spark, but the burner does not ignite

If a spark occurs when turned on, but no fire occurs, the cause is the thermocouple. It must be replaced if repair is not possible. Updating the solenoid valve also gives a positive result. After this, the stove works stably.

Advice! Check the condition of the ignition unit - if it is in order, but a spark does not occur, the problem lies in the unit or power supply wire.

If there is a spark, the flame burns, but goes out quickly, press the button to supply gas for a long time. Perhaps the sensors responsible for supplying the flame do not have time to warm up.
