The flame does not ignite in the Bosch geyser: finding the cause of the malfunction and recommendations for repair

The reasons

It is worth considering that breakdowns can be of a very different nature. For example:

• the flame did not ignite (it clicks, there is a spark, but it does not work or there is no reaction to switching on at all);
• goes out immediately or after a short time (both with automatic and manual ignition);
• the fire goes out when you try to turn on the water, increase the pressure or weaken it;
• the flame is lit, the water comes out a little warm, and then the column goes out;
• the column pops, cracks, mini-explosions appear when turned on;
• piezo ignition does not work;
• the piezo constantly works, but when ignited, the flame goes out;
• the automatic column does not burn, while there is a smell of gas;
• when the valve is opened, the DHW rod does not move.

Column malfunctions can be divided into breakdowns caused by external factors, and purely internal ones. The former are not related to details within the unit itself and depend on additional details or external influences (for example, adding temperature).

External factors

External breakdowns are as follows.

• The most common situation is the lack of draft in the column chimney. If it is not cleaned, then it will become clogged with dust, dirt, and the combustion products will not find a drain and will extinguish the burner. Then, when the security system is triggered, the gas supply will be shut off.
• A foreign object could accidentally be in the chimney.
• The unit could simply run out of battery or batteries. This type of fault exists only if there is an ignition, which automatically operates on batteries.

• If the appliance does not work, after the first installation or due to repair work on the plumbing system, then there is a high probability that the hot water supply line was simply connected to the wrong place.
• Reduced water pressure. It is necessary to evaluate the water pressure (it will be weakened, water will flow in a thin stream). The ignition will stop working at low pressure, so the reason is no longer in the column, but in the water pipes. Although, it is likely that the filter itself, installed in front of the column, is clogged with something.
• A faulty faucet adding too much cold water, so the water in the column itself heats up too much and extinguishes it.
• Electronics. In modern columns there are a large number of control modules and sensors that control the operation of the entire unit. Their failures can lead to the fact that the gas will stop igniting.

Internal breakdowns

Internal factors are as follows.

• Incorrectly configured water heater. Due to the change of seasons, the water temperature also changes, so the column needs to be regulated, which is often forgotten to do.
• The membrane on the water unit has failed. If the membrane is many years old, then it could lose elasticity, crack, deform, become covered with lime deposits.
• Clogged filters or heat exchanger with soot and scale.
• Pilot or main burner is clogged with dirt.
• Problems with the gas outlet sensor.
• Popping or small explosions when trying to turn on the equipment may occur due to insufficient draft in the ventilation or blockages in various parts of the water heater.

The wick does not want to light up

If the burner refuses to do its job, or does it poorly, there may also be several culprits:

1. The piezoelectric element cannot work. Problems with the igniter are typical for Zerten and Astra columns. It must always be on, and it can be triggered when a button is pressed or when the mixer is opened. If this does not happen, the reasons should be looked for in the jets, which can become clogged. In this case, you will have to disassemble the device, get rid of the casing and clean these holes. This can be done with thin wire.
2. The automatic column ignites too long. Here the fault lies with the batteries, which are responsible for the appearance of a spark that ignites the burner. If there is no spark, try changing them.
3. Problems, perhaps, in the hydrodynamic system - the generator broke down, due to the rotation of which energy is generated to produce a spark. This kind of repair is not recommended to be done at home, because you have to go to the service center.

Water doesn't heat up well

Solution:

1. Choose a unit with more power.
2. Turn on hot water in different rooms alternately.

Blockage can occur in the burner or heat exchanger due to excess soot. It will be signaled by a red-white color of the flame with normal water pressure.

The solution is to clean the column, preferably with the help of a specialist.

If at first there is water of an acceptable temperature, but gradually it becomes colder, the flame of the column is blue, and the light is weak, then the problem is in the integrity of the membrane. Cold water is wedged into the hot stream, and the outlet temperature drops.

The solution is to replace the membrane.

The solution is to switch the hoses.

Blame the draft in the chimney

The main burner may go on strike if the chimney pipe is clogged. Leaves, debris and soot clogging the channel cause the draft to decrease. Sometimes to such an extent that a protective system works in the column, shutting off the gas.

To make sure the version is correct, you need to open a balcony, window or window, and then attach a paper sheet to the vent (matches are evil). If there is a draft, then the sheet will stick to the grate. Otherwise, there will be only one option left - turn off the heater and call a chimney sweep team.

If your column is from the manufacturers Beretta, Ariston or Bosch, then it is equipped with a sensor that controls traction. In its absence, the gas stops flowing.

3 Types of breakdowns of gas water heaters

Hot water equipment is far from being an innovative development; the first gas column was invented and put on sale at the end of the 19th century. For almost 120 years of operation of household appliances of this type, users have been able to identify the most common types of device breakdowns. During the operation of the unit, the following types of failures and malfunctions may occur:

• the inability to light the wick, which is also called the igniter;
• short burning of a lit wick and its abrupt shutdown a few minutes after ignition;
• a short time of operation of the device, followed by a lightning-fast shutdown or gradual attenuation;
• smoking kindled equipment;
• abnormal functioning of the heating element, which does not heat the water when the toggle switch is on.

Possible reasons

In the case of incorrectly connected pipes, the water heater protection system itself shuts off the gas supply, which is why it does not turn on. The pipe connection scheme 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 connected on the right.

It is also necessary to make sure that all gas supply valves are in the open position. It may well be that after installing new equipment, you simply forgot to turn on one of them. All faucets with yellow handles must be open.

No or poor draft in the chimney.

Accumulated soot, construction debris or other foreign objects that have entered the chimney can prevent the removal of combustion products through the chimney, which creates a danger not only to health, but also to the lives of residents.

hood

The presence of draft in the chimney can be easily checked by yourself. To do this, you just need to bring a burning match to the inlet. If its flame rushes in the direction of the hole, then the chimney is working properly. Otherwise, you will have to look for the reason why there is no traction. As you can see, an ordinary match can help eliminate a dangerous malfunction and protect your household from carbon monoxide poisoning.

If there is no draft, make sure that there are no obstacles above the outlet of the ventilation shaft, such as a satellite dish. In this case, the problem is completely solved without seeking help from specialists.

If no external circumstances interfere with the correct operation of the chimney, then, definitely, you are dealing with its pollution. What to do in this situation? Of course, you can try to clean it yourself, but there is a possibility of damage to the branches from neighboring apartments.

Increased relay sensitivity.

The most likely cause of the malfunction is the increased sensitivity of the thermal relay, the protection of which is triggered by overheating, stops the gas supply and the column goes out.

Causes of breakdowns and their elimination

Despite the simplicity of design, unpretentiousness in operation, the flow heater is not immune from breakdowns. If the geyser of the Vector brand does not turn on, do not panic. There can be several reasons for the problem, and most of them can be fixed on your own.

Problem # 1 - lack of traction in the column

The lack of draft indicates that the products of combustion cannot be quickly removed from the room. This poses a danger to users, so the sensor turns off the geyser.

Sometimes the burner ignites, but immediately goes out. This can happen when there is not enough air to burn the gas - the flame goes out due to a lack of oxygen to support combustion.

In any case, you first need to check the draft by bringing a burning match to a special hole on the column body. If the flame is directed inward, then the chimney is working normally, the combustion products will be quickly removed, and the cause of the malfunction is different. If the flame remains motionless, directed upwards or towards the user, then it is worth carefully inspecting the chimney, cleaning it.

Soot gets into the air along with the products of combustion. It gradually settles on the walls of the chimney, narrowing its opening. As a result, traction is lost. The problem is solved by thorough cleaning of the chimney

Problem #2 - Difficulties with water pressure

Another reason why the household geyser of the Vector brand does not ignite may be the low pressure of cold water or its complete absence. Before you start looking for a solution to the problem, you need to make sure that cold water is supplied without interruption, evaluate its pressure. If there is insufficient water pressure in the system, the solution may be to install a pump or replace old, clogged pipes.

If there are no problems with the water supply, it is worth moving on to inspecting the column. The solution to the issue may be to adjust the water supply to the column. To do this, the corresponding valve must be fully opened.

Another cause of insufficient water pressure in the column is a clogged filter.To inspect it, it is necessary to shut off the water and gas supply with valves, unscrew the nuts, rinse the grid. If cleaning fails, the filter will have to be replaced.

It will take a few minutes to inspect the filter. However, in some cases, one flush is not enough, a complete replacement of the part is required.

Problem #3 - insufficient gas pressure

Sometimes the gas pressure is not enough to ignite the flow column, its normal operation. However, this problem cannot be solved on its own. You need to contact the gas service.

Problem # 4 - no ignition when turned on

The presence of an electric ignition system ensures the comfort of using the gas column, eliminates the use of a wick that is constantly on fire. However, it is this element that can cause a malfunction of the device.

When the tap is opened, automatic ignition should work. This action is accompanied by a characteristic crack. If the ignition does not work or the spark is too weak to ignite the gas, the column will not be able to connect. Replacing the batteries will solve this problem.

Batteries are required for the smooth operation of an instantaneous water heater. When the batteries are discharged, the electric ignition does not work, the column does not turn on

Problem # 5 - the presence of blockages in the tubes

Water and gas pass through the gas column Vector in the process of operation. The use of filters allows you to clean them from unnecessary impurities. However, the presence of blockages can cause the device to simply not turn on.

However, the filter is not always able to bring the water to an ideal state. Soluble salts get inside the heater together with the liquid, settle on the walls of the heat exchanger.As a result, the patency of thin tubes is impaired.

Specialists remove scale with the help of specialized reagents. A home master can deal with it using a solution of citric acid or vinegar. To clean the heat exchanger, you need to remove it, place it in a warm solution with the addition of vinegar. You can also use special purchased products - "chemistry" designed to clean heat exchangers.

It is better to entrust the elimination of blockage of the heat exchanger to qualified craftsmen, since the tubes are fragile and, in the absence of specialized skills, they are easy to damage

We discussed in detail about cleaning and repairing the heat exchanger in the next article.

Electronics failure

The draft sensor in geysers is usually located on top. It is attached to the chimney.

Modern geysers have on board a lot of electronic components and sensors - they are not only in the simplest models. Sensors control the draft and the presence of a flame (ionization control), monitor the temperature of the water and automatically adjust the degree of its heating. If one of the sensors fails, the geyser will malfunction. The most typical malfunction is a breakdown of the thrust sensor in the exhaust manifold. As a result of this, the electronics will not give the go-ahead for ignition. Breakdowns also haunt the electronic modules installed in many gas water heaters. And their repair is complicated by the fact that this requires special knowledge in the field of electronics and circuitry. If you are sure that the electronic components are malfunctioning, but do not have the necessary knowledge, feel free to call the wizard.

The problem with blockages

At the entrance to the gas column, filters are often placed that filter out small solid impurities contained in the water. Salts also settle here, becoming an obstacle to the normal passage of liquid. As a result, the column ceases to light up and delight the household with hot water. In this case, you need to turn off the water supply, unscrew the filter and clean it. If the condition of the filter is very severe, then it is easier to replace it.

To clean the heat exchanger, soak it in a solution of water and detergent, and pour citric acid into the tubes to the top and leave for half an hour.

Also, during the long-term operation of the column, the tubes or the heat exchanger may become clogged in it. In this case, you need to check the patency of the water unit and make sure the patency of the heat exchanger. Blockages are eliminated by washing with special reagents - to purchase them, contact your nearest hardware store. After flushing, the performance of your gas column will be restored.

In order to prevent clogging of the inside of the column with deposits, install a decent filter at the column inlet, which will remove small impurities and soften hard water.

1 What are the types of Oasis speakers?

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

1. Flowing water heaters.
2. Storage water heaters.

The mechanism of action and heating of water depending on the type of device will be different. Another type should also be distinguished - 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.

Geyser in the kitchen

All of the above devices should be installed where there are no stationary chimneys. All these devices work from the mains and do not require additional batteries. The operation of such a column is carried out in the forced emission of combustion products. Turn turbo on and off geyser Oasis by opening a faucet. It can also be installed standalone.

Advantages of gas water heaters Turbo:

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

flow columns

Now we will analyze the popular flow column. If you decide to put such a column in your house, then you don’t have to worry about the fact that you will be left without hot water, even despite the slight pressure.

Geyser manufacturer

It should be noted that Oasis water heaters are made in such a way that they have different boiling water capacities. In addition, we can say that the Oasis geyser device is made according to the flow type. Such a column can produce from 5-15 liters of hot water within 1-2 minutes.

But the positive aspects of the Oasis flow columns:

1. Structures are enabled automatically.
2. This column does not depend on electricity, but works due to replaceable batteries.
3. Reasonable price for a gas water heater Oasis.
4. Clear and legible instructions for the Oasis geyser.
5. The presence of a regulator in the column that controls the heating process depending on the external temperature and what time of the year it is at this stage.
6. It is economic that allows to minimize costs of the consumer.

One of the Oasis views

It should also be mentioned from consumer reviews that the manufacturer of the gas column Oasis 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 off from the consumer.

storage columns

The storage and flow devices mentioned above differ greatly from each other in terms of 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 flow columns do not have such a storage tank.

Oasis column device

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

• A simple repair of the Oasis geyser can be done by a person who does not have special skills.
• There is always plenty of hot water available.
• Economy at 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 customer reviews, they constantly notice that the Oasis column is problematic to place 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 geyser Oasis

Incorrect water heating

The cause of this problem may be the wrong choice of the power of the installation. To do this, when buying, you need to make sure that the Bosch gas water heater or another company has the necessary characteristics for your home.In addition, there may be a blockage of the device. This is confirmed by the presence of soot and the uncharacteristic color of the flame. With insufficient heating, you can try to adjust the energy supply. This is done with a special crane.

There is also the opposite situation - the water is too hot. Here, the Bosch gas column does not require repair, since this is not considered a malfunction. This is because the temperature of the water in the water supply is warmer in the summer, and the pressure drops. Many geysers are not designed for this mode. The characteristics of gas water heaters include the optimal water pressure at which the normal operation of the unit is ensured. The solution to this problem is as follows: it is necessary to reduce the supply of energy.

The main ways to turn on gas water heaters

Today, various options for switching on gas water heating equipment are practiced, the choice of which directly depends on the design features of the device.

In any case, before turning on the gas column, a number of measures are required that will allow the trouble-free operation of such equipment. Be sure to open the taps for the supply of fuel and water to the system of the water heater.

How to light a gas column: manual ignition

This method of ignition is practiced when operating outdated models of gas water heaters and involves lighting the wick with matches.

The manual ignition technology is simple, and consists in opening the water supply connected to the water heating equipment and the main gas supply valve, after which the wick is ignited.

A decrease in water pressure is not accompanied by a shutdown of the device, so the shutdown is also carried out manually.

Piezo ignition

The presence of a piezo ignition in the gas column greatly facilitates the operation and maintenance of such equipment.

The wick in such designs is ignited by pressing a special button. The ignition of the main gas burner requires the regulator to be turned on for gas supply.

Pressing the button produces a spark and ignites the wick.

In models with piezo ignition, the location of the regulator in its original position and turning off the water supply does not extinguish the ignition wick, and the main disadvantage of such equipment is increased fuel consumption.

Auto power on

To date, gas water heating equipment is presented in a wide range, and improved convenient models with an automatic system for igniting the wick and igniting the main burner have become especially in demand among consumers.

As a rule, such columns have an installed turbine driven by water pressure.

Starting the turbine causes automatic operation, but in this case, rather high demands are placed on the water pressure in the system.

Possible other faults

A heavy burden of guilt may also lie on other smart devices in the gas column.

Failure of the electronics that control the perfect operation will lead to the opposite result. Sometimes the wiring is damaged, sometimes there are malfunctions in the operation of various sensors. Such "catastrophes" require the intervention of a specialist who can accurately determine the cause with the help of diagnostic equipment, and then repair the unit.

Incorrect setting of the igniter can lead to the fact that if there is insufficient gas pressure, the spark does not reach the comb, and the fuel misses the target. Therefore, the installation of the electrode must be carried out exactly in the center of the burner, then there will be no problems with ignition.

Improper operation of the column can also lead to trouble, threatening even the failure of the device. We are talking about the inclusion of cold water during operation of the device. At this moment, the column goes out. This is due to the fact that the pressure of hot water becomes too small. Therefore, it is precisely the regulation of hot water of a certain temperature that is the main condition for the smooth operation of the device.

Problems with ignition

Why does the gas column not light up? It happens that there is very little gas pressure in the pipes. See how the burners of the gas stove burn. This supply of fuel must be reported to the gas service.

Water heaters Neva and Vector have electric ignition. If the draft, pressure, gas supply are normal, and the column does not ignite, the reason may be in the generation of a spark. When the tap is opened, a characteristic crack should be heard. We are trying to replace the batteries.

With hydrodynamic ignition, the operation of the generator should be checked. Such repairs will require certain knowledge and skills.

Geyser Astra automatic with electric ignition. The reasons that make it impossible to ignite the device are the same. It may also not light up if the gas and water shut-off valves are closed. You just have to open them.

Other reasons

The geyser lights up and goes out due to the failure of the mechanism that opens access to gas. It is a solenoid valve and a servomotor. We'll have to call the master.

The tubes in the column can become clogged over time.You need to make sure they are passable. In case of blockages, special flushing agents are used.

In geysers, burners often become clogged. Why is this happening? The reason is the accumulation of soot. It is necessary to disassemble the column, remove the burner and clean it with any tools. Clean the heat exchanger at the same time.

The membrane may rupture. It's hard to buy.

You need to check all the details. Many speakers have electronic units and sensors. For example, in the Neva geyser, the thrust sensor often breaks down, as a result, the device will not light up.

Electronic components, most likely, will have to be repaired by the master.

So, you know what measures to take if the geyser does not ignite. We fix many breakdowns ourselves, and in more serious cases we turn to specialists.
When repairing a geyser, all safety measures must be observed. Always turn off the gas. It is better to clean the gas column in the open air.

Overheat

Most often, overheating occurs for the following reasons:

1. The user dilutes hot water with cold water. Due to the admixture of cold water, the hot water consumption is reduced, therefore, the heat extraction is reduced and the water in the heat exchanger overheats. Remember: you can regulate the temperature of hot water only by changing its pressure or using the regulator on the column.
2. The heat exchanger is clogged in some place. This also leads to a decrease in water consumption with subsequent overheating. You can guess what happened by the clearly weakened pressure of hot water, despite the fact that the cold one is flowing regularly. To prevent such troubles, the heat exchanger must be periodically flushed with special compositions to combat scale.

If the strainer (mud) installed on the water pipe in front of the column is clogged, the flow rate will also drop in this case with all the ensuing consequences.

Traction problem

If the chimney is clogged with soot or debris, the exit of combustion products is complicated. There are such threats:

1. The carbon monoxide returns with the air to the machine and extinguishes the burner. The defense of the column is triggered, stopping its operation.
2. The situation is as in paragraph 1, only the return of a dangerous mixture occurs into the room. In this case, the health of residents can be seriously affected.

The ventilation tunnel needs to be checked. A lit match is brought to his entrance.

If there is a deviation of the fire inward, then there are no problems with traction. Otherwise, action is required:

1. Checking the presence of an antenna above the exit of the ventilation shaft. Ask the neighbors to rearrange it.
2. Calling specialists to clean this channel.
