Gas water heaters in everyday life are becoming an indispensable thing both in private apartments and in country houses and ordinary dachas. Manufacturers of geysers nowadays make a good and inexpensive product from our manufacturer, since today the market is in full swing and competition is very high.
Oasis geysers are popular heating devices among consumers. These models are inexpensive designs. They include economy, reasonable price and popularity. You can also read a lot of positive reviews about the Oasis geyser, which speaks volumes about 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 to customer reviews of Oasis geysers.
Common problems
Let's look at what breakdowns occur with household gas instantaneous water heaters. These breakdowns are typical for water heaters Neva, Oasis, etc.
If the water heater does not light up
There is no need to sound the alarm right away. Some problems are not very serious. With these problems, the water heater may make a popping noise when turned on.
Lack of traction
There is no draft in the exhaust duct. Maybe some object got in there and blocked the exhaust duct.
Or maybe there are a lot of combustion products in this channel - soot - and it is clogged. The circuit breaker tripped and the column stopped working. We need to check for traction. Bring a match to the ventilation; if there is draft, the flame will be directed towards the channel. If there is no draft, then you need to call a chimney sweep and clean the channel.
You may not be able to get by with cleaning just one channel. Some of the soot accumulates on the column itself, so you can vacuum the column to remove it.
In the absence of the necessary draft, the water heater may turn on, work a little and go out. Try opening a window to increase the amount of air.
Old batteries
Another reason why the water heater does not turn on is that the battery life has expired, the batteries in the electronic device have simply run out. Change them and the problem will be fixed.
Weak water pressure
Maybe there is insufficient cold water pressure. This is easy to check by opening the water tap. If the cold water pressure is low, you need to call the management company and find out the reason.
The shower is clogged
The following reason may arise: there is hot water pressure in the tap, but when you switch to the shower, it stops flowing. Check to see if the shower itself is clogged.
The water heater does not heat water or does not heat water well
Most likely this is a water node problem. There is a rubber membrane there, which for some reason stops responding to water pressure, which, in turn, leads to the gas supply being cut off. There may be a crack in the membrane, salt deposits may have accumulated due to hard water, or it may simply be clogged.
The assembly must be disassembled, the membrane cleaned or replaced, it is better to replace it with silicone. It is also possible that the coarse filter installed in the water unit is clogged.
Column clogged
The water may not heat well due to a clog in the column itself. This is indicated by the soot that forms above it and the changed color of the gas.
Repair
Low power
Your speaker may have low power, so carefully read the characteristics of your unit.
Weak gas pressure
Water will not heat up well if the gas pressure is low. In this case, call the gas service.
The water is very hot
This is not a breakdown of your unit. You just need to reduce the gas supply, turn the tap located on the gas pipe in front of the column.
Smell of gas
If you suddenly smell gas, you shouldn’t deal with this problem yourself. Call the gas service immediately. There should be no gas smell. Also, if, when you turn on the column, the characteristic sound of gas turning on does not follow, that is, gas does not flow, you should contact specialists, gas workers.
The gas water heater does not light up, reasons
Let's look at identifying the reasons why a gas water heater goes out and how to eliminate them using the Oasis water heater as an example, since other water heaters have similar malfunctions.
It should burn steadily and the color should be blue. A yellow-red color and a small flame indicate the need to clean the pilot nozzles. So, we found out how these devices work, looked at their main faults and how to eliminate them. These geyser repair instructions will help you find out the cause of the breakdown and fix it as soon as possible.
- Incorrect pipe connections.
- No or poor draft in the chimney.
- Increased relay sensitivity.
- Malfunction of the ignition system.
- Membrane damage.
In case of incorrectly connected pipes, the water heater protection system itself blocks the gas supply, which is why it does not turn on.
No or poor draft in the chimney.
Accumulated soot, construction debris or other foreign objects entering the chimney can prevent combustion products from being removed through the chimney, which poses a danger not only to the health, but also to the lives of residents.
The pipe connection diagram is very simple: The gas supply pipe is connected on the left, the cold water supply pipe is connected in the center, and the hot water outlet pipe is on the right.
Increased relay sensitivity.
The most likely cause of the malfunction is the increased sensitivity of the thermal relay, the protection of which is activated against overheating, stops the gas supply and the column goes out.
If there is no draft, make sure that there are no obstacles above the ventilation shaft exit, such as a satellite dish. In this case, the problem can be completely solved without seeking help from specialists.
Temporary. To reduce the temperature in the room, you can open the window slightly.
At the same time, due to the decrease in temperature, the relay protection against overheating will stop turning on and the water heater will not go out. Final. You can completely get rid of the problem only by replacing the bad relay.
Malfunction of the ignition system.
Weak or completely absent cold water pressure.
The procedure is as follows: One of the reasons why a gas water heater does not ignite is a faulty membrane. If it has mechanical damage or has lost elasticity, then normal operation of the column becomes impossible.
Repair
If suddenly a leak appears in the instantaneous water heater, then perhaps a fistula has formed in the heat exchanger. If you want to do the repairs yourself, you will need to disassemble the water heater. Let's consider this process using the Neva column as an example.
We begin the repair by turning off the water and gas supplies by turning off the taps.
We remove the casing. To do this, unscrew the two screws at the bottom of the rear wall. By pulling the casing towards you, you need to recess two knobs: one is a piezo igniter, the other is gas adjustment. Then lift the cover up and remove it.
This is what the heat exchanger of a Neva gas water heater looks like:
Having found a fistula, you can solder it using a soldering iron. To do this, you need to drain the water from the heat exchanger. Open the hot water tap and unscrew the nut from the cold water supply pipe. The water will drain, but not all of it. The rest must be blown out using some kind of hose, blown out with your mouth so that the remaining water comes out. The pipes can then be soldered in the usual way. Perhaps the fistula is in the place where it is adjacent to the gas water heater. In this case, you need to disassemble the entire column and remove the heat exchanger. Such repairs are much more difficult to make, since it will be necessary to disconnect the gas pipe. You don’t have to solder the heat exchanger yourself, but replace it with a new one. Watch the video for repairing the Neva water heater:
There may be a leak at the point where the geyser pipe connects to the water supply. In this case, you need to change the gasket in the union nut.
Descaling
Insufficient water heating can occur when scale forms inside instantaneous water heaters. This can be cleaned.
For example, the simplest instantaneous water heater Oasis, made in China, can be cleaned without disassembling or removing it from the wall. Using a circulation pump, circulate water and acetic acid for about 40 minutes to dissolve the scale. Then rinse well with running water. Another problem encountered when using the Oasis: suddenly the speaker starts to heat up and turns off after a while. Be sure to clean the chimney. And until a specialist arrives, you cannot use the column. If the draft is good, then you can disassemble the Oasis column yourself and clean the heat exchanger; this may be the reason, and you will not need additional repairs.
The designs of all modern instantaneous water heaters provide for automatic shutdown of the gas supply when the water is turned off or the chimney is clogged. Therefore, there is no need to be afraid that a gas leak will occur.
It is not uncommon for a gas water heater to fail to light; it only causes headaches and inconvenience. It would seem that this unit should make life easier for people in the absence of a centralized hot water supply, but that was not the case. Malfunctions occur almost immediately after purchase; this mainly applies to Chinese speakers.
A little background
So we became the “lucky” owners of one of these. Literally immediately after the purchase, the heat exchanger leaked; as it turned out, we were given a repaired return. With great difficulty, we managed to make an exchange after written claims for pre-trial settlement to the store. According to the rules of the store, exchange is not possible, but where is this stated in the law? Even sending it to a service center is not so easy: first you need to call the gas workers so that they draw up a breakdown report and certify it with seals and signatures; Give the certificate to the warranty service along with the column, where a decision on repairs will be made within three days. And we have to sit without hot water all this time!
If the seller tells you that gas equipment cannot be returned or exchanged, remember, this is a lie. In the event that you purchased a product with a manufacturing defect, you are required to replace it with a new one at your request or return the money if a similar product is not available.
After several months of operation of the second unit, a malfunction appeared: the gas water heater does not ignite. I immediately remembered the procedure that must be followed for repairs under warranty. Therefore, it was decided to repair the geyser with your own hands, or at least try.

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.
Debugg
This is probably the reason why the gas water heater does not light up. Unscrew the screws that hold the electrodes.
It was discovered that soot had formed on the non-working one. Let's try to remove it and then check if this was the reason. It may have completely burned out and needs to be replaced. Use a fine file or sandpaper to remove carbon deposits.
We put everything back the way it was and try it. We move the relay tongue again, a spark appears.
We open the gas valve; just in case, it is better to close it when carrying out repairs. We turn the hot tap, the gas water heater starts working, the gas ignites.
This simple repair of a geyser was done with my own hands; in just 20 minutes the cause of the inoperability was eliminated. And there was no need to go through the painful procedure of transferring the column to the store’s service center.
To satisfy consumer needs for hot water, many water heating devices, both electric and gas, have been developed. For reliable operation, they are equipped with new control and protection systems for safe and long-term operation. But no matter how reliable water heaters are, over time they also fail. Repair of geysers, as a rule, should be carried out by professionals, but in some cases it is possible to troubleshoot problems yourself.
The geyser is a fairly unpretentious device to operate and can operate for a long time without breakdowns. But if they happen, then you can diagnose the geyser for proper repair of the device using the following signs:
- power problems;
- water unit malfunction;
- problems with the gas block;
- incorrect installation.
If problems are discovered in the gas block, then you cannot repair the Ariston gas water heater or repair the Junkers gas water heater, as well as any other water heater yourself. The breakdown must be corrected by a qualified technician. In other cases, you can try to cope on your own.

Power problems
For normal operation of most components inside the unit, a stable power supply is required. Therefore, if malfunctions of the geyser appear in the form of malfunctions, which are characterized by the fact that the flame does not ignite or goes out during operation of the device, then a possible cause of such a problem may be a lack of current power
supplied from batteries.
This does not apply to units without electronic components in the design. For example, you will not find it in the Neva 3208 unit, which you want to repair, or when repairing an old model Astra gas water heater.
Often, when repairing an Oasis gas water heater, as well as a Junkers gas water heater, users are misled by the fact that the LCD display lights up and there seem to be no problems with power supply. But it should be borne in mind that ignition requires a sufficient charge to form a spark in the spark plug. In addition to this, the electronic unit also requires power to transmit it to the solenoid valve in order for it to be in the “open” state. Therefore, if the batteries are already low, then there may not be enough power to ensure the operation of these modules.
In the instructions for the water heater, the manufacturer indicates the operating time of one set of batteries. As you might guess, this value is approximate, and it depends on the quality of the batteries used. When purchasing batteries, you should pay attention to the markings on them. For long-term operation of the gas water heater, it is recommended to choose batteries marked LR20
. This means that they are alkaline, that is, alkaline.
Cheaper ones, labeled R20, fail very quickly and cannot cope with a constant load. The ideal option is CR20 lithium batteries. Their main difference from alkaline ones is their high capacity, stable current generated, and long-term operation, several times longer than the service life of LR20 batteries. The only drawback of batteries marked CR20 is their high cost.
. So, buying LR20 alkaline batteries will be the right choice in terms of efficiency and cost-effectiveness.
Remember: never buy batteries from street kiosks, much less from trays in the market. This recommendation especially applies to the winter period, since the cold causes the batteries to lose their charge.

Removing the column lining
Repairing a geyser with your own hands, such as replacing batteries, is the only way to troubleshoot problems that does not require removing the outer casing of the unit. To repair geysers Vector, Oasis and any other malfunctions, you will need to open the device. To begin removing the casing from the water heater, you need to turn off all the water and gas supply valves, and then do the following (for example, we take the Neva 5611 water heater, which we will disassemble on the table).
How to prevent breakdown of the Oasis geyser
The specialists of the Myguru website in Moscow will cope with any malfunction in any model of the Oasis brand.
In order to prevent a situation where repair of the Oasis geyser is required, it is necessary to properly care for gas equipment and operate it correctly. These are the recommendations that can be read in the instructions for geysers. Here are some operating tips:
- You need to monitor the battery charge.
- When turning off the unit, you must first turn off the water.
- If the unit is turned off for a long time, then it is necessary to shut off the supply of bitter water.
- Periodically clean the column from scale.
- Use only the gas recommended by the manufacturer.
- Do not turn on the column if there is no traction.
- Do not carry out repairs yourself.
You can submit a request for repair of the Oasis model on our service website. At the same time, do not forget to provide useful information: the exact name of the model, existing problems, your own contacts.
Water unit malfunction
Most often, geyser repairs are made due to a faulty water block. Its work is that, under the influence of liquid pressure, the membrane located inside it, arching, transmits movement to the rod, and it then moves the pusher of the gas unit. As a result, the spring valve opens and the electrical power supply to the control module is turned on. Therefore, if the water unit is faulty, the device will not start.
A broken water block can be determined by external signs.
.
If you notice even one sign, the unit will need to be removed and repaired. The water unit can only be removed together with the gas module, since they are a single structure. You can do this in the following way:
- after you have made sure that the gas valve on the pipe is in the closed state, you can disconnect the supply hose (a);
- similarly, when the water supply is turned off, the nut on the water block pipe (b) is unscrewed;
- then, using a wrench, you need to unscrew the nut that connects the water block to the heat exchanger (c);
- disconnect the terminal block (d) on the conductors connecting the solenoid valve to the control module;
- wires (d) going to the switch are disconnected in the same way;
- using a screwdriver, you need to unscrew the 2 screws (e) attaching the pipe to the water-gas unit, through which fuel is supplied to the burner manifold;
- After unscrewing the fasteners, the entire assembly can be easily removed from the device.
Repairing a Neva 3208 gas water heater due to a faulty “frog” is similar and intuitive, although the internal appearance of the unit is slightly different. The Neva 4511 gas water heater can be disassembled in the same way, and repairing it yourself is quite feasible.
a Chinese gas water heater repaired?
, the size of the water node is always surprising. It is quite small in size, and to disassemble the “frog” you only need to unscrew 4 screws.
Heat exchanger repair
Repair of the geyser heat exchanger will be required in the following cases:
- if insufficient water pressure is noticed at the outlet of the gas water heater;
- low heating of the liquid;
- Noises are heard when the unit is operating.
The reason for all this may be scale
, formed on the inner surface of copper tubes.
Therefore, the heat transfer and throughput of the latter are reduced. In addition, if the unit has not been serviced for a long time, dust and soot
, which also interferes with the water heating process. The heat exchanger is easy to remove.
Repair of heat exchangers of any geysers begins with washing them under a strong stream of water to remove dust and other contaminants. After which it is recommended to immerse it in water for half an hour with the addition of detergent, for example, for dishes.
Cleaning of the unit continues with a small, soft brush, after which it is washed again under running water. Water heater tubes clogged with scale are cleaned with a strong flow of water in the opposite direction. If the scale is not completely removed, you will have to pour a special acid solution
. To prepare it, you can use regular citric acid. You need to take 100 g of acid and dilute it in 1 liter of water heated to 40C. This solution is poured into the heat exchanger pipe until it emerges from the other. The reaction will be immediately visible in the form of escaping foam. The poured solution is left for 15 minutes, after which all channels of the unit are thoroughly washed under water pressure.
If you are not satisfied with the result, dissolving the scale can be repeated.
In this way, the heat exchanger of the gas water heater Neva Lux, Dion, KGI, Selena, as well as the gas water heater Neva Transit is washed.
