Vector gas columns – Possible causes of malfunction and how to repair them

Many homes are built with gas heating systems as the foundation, which offer warmth and comfort in the colder months. Vector gas columns are particularly noteworthy among the various gas heating options available because of their dependability and efficiency. They are prone to malfunctions over time, though, just like any mechanical system. Keeping your home comfortable and functional requires knowing what might be causing these problems and how to fix them.

When abnormal behavior occurs in your vector gas column, it can be both annoying and worrisome. The good news is that a lot of common problems can be identified and fixed without the assistance of a specialist. You can effectively troubleshoot and possibly save time and money on repairs by becoming familiar with the potential causes of malfunctions.

Inadequate maintenance is one of the main causes of vector gas column malfunctions. The system’s performance may be impacted over time by the accumulation of dust, debris, and other contaminants. Cleaning and maintenance must be done on a regular basis to avoid these problems. It’s also important to take care of routine maintenance promptly because postponing it can result in more serious issues later on.

Faulty parts are another frequent cause of vector gas column malfunctions. The system as a whole may malfunction due to the gradual deterioration of individual parts, such as a broken gas valve, a pilot light that isn’t working, or a thermocouple that is worn out. Thankfully, you can easily replace a lot of these parts to get your gas column operating properly again.

In certain instances, the problem might not be with the vector gas column itself, but rather with outside variables like problems with the gas supply or incorrect installation. It’s imperative to seek the assistance of a trained expert to evaluate the situation and make any required repairs or adjustments if you believe the issue goes beyond the gas column.

Other malfunctions of gas boilers

Electronics are used to operate modern columns. The gadgets are literally jam-packed with electronic modules and sensors. Unsatisfactory operation of the unit can result from even a small malfunction of one of the sensors. You require specialized equipment to solve the problem; you cannot do it alone.

The majority of gas heater owners use the faucet to add cold water to adjust the temperature if the water is too hot. In this instance, the columns might disappear. The units’ manufacturers advise against using the column in this mode. It is preferable to use the heater at a lower heating setting.

If the igniter is not set correctly, the burner may also not work. For this reason, the gas heater does not ignite right away.

It is crucial that the type and design of the igniter be fully matched by the gas pressure in the mains. The burner’s edge has a comb, and the electrode needs to be positioned so that the spark hits the comb directly.

Fuel descends when there is insufficient gas pressure. The electrode needs to be positioned roughly in the burner’s center. The ignition system will then function more steadily.

Common errors with individual columns:

• There are frequent problems with the solenoid valve in Astra columns. If the mixer is not adjusted correctly, the igniter will not operate consistently.
• In models from "Ariston" there are problems with the water unit. Also, experts emphasize the rapid wear of the diaphragm.
• In the columns of the brand "Oasis" there are malfunctions associated with the burner, as well as with the diaphragm.
• In models from "Amina" there is a very fast discharge of batteries – owners have to change batteries frequently.
• In the columns of the brand "Rossiyanka M" there are often problems with the violation of valves and clogged filters. But on Dion columns there are problems with the heat exchanger. What is the cause? The heat exchanger often burns out.

Eliminating draught disturbances

Try using a regular match to check for draughts. It will be directed toward the chimney if you bring it close to it to see if there is a draft.

If there is no draught, the gas heater will not light and users will not get hot water. Many speakers have draft sensors and if they show insufficient draft, ignition will not be possible. There may be situations when the flame ignites and immediately goes out – this is due to the fact that the products of combustion simply have nowhere to go, they remain in the combustion chamber, and the flame goes out due to a lack of oxygen. Lack of draft will require inspection of the flue gas collector and the chimney itself. If there are clogs here, they can prevent the normal passage of combustion products. The appliance perceives this as a lack of draught and does not allow the gas to ignite (or the gas goes out as soon as it is switched on). Unfortunately, independently check only the part of the chimney that can be seen up to the entrance to the wall – further work should be carried out by specialists. If the house is private, you can try to deal with the chimney yourself.

Turning on the appliance

Installing the batteries is the first step. To accomplish this, unseal the battery compartment, place the batteries inside, and note their polarity. Next, open the gas and cold water valves. The closest faucet’s hot liquid faucet should be opened.

The burner is ignited at the precise moment when the liquid passes through the water assembly due to a spark ignition. Air may build up in the gas line when the appliance is turned on for the first time or after a prolonged period of inactivity. To get rid of this air, open the mixer multiple times, hold it for a minute, and then close it.

When the liquid pressure in the system drops, the Vektor JSD 20 will be able to be turned on. If the burner ignites, turn the water head adjustment lever (to the right).

Operating Instructions

You should carefully familiarize yourself with the appliance’s use and safety instructions before turning on the gas heater and using it.

• When operating gas equipment, only the type of gas recommended by the manufacturer should be used.
• When switching on the appliance for the first time, be aware that air may accumulate in the pipes and the burner may not light up immediately. Therefore, the ignition should be performed twice with a short interval between attempts.
• Setting the heating parameters is carried out by turning the regulator located on the body of the appliance. At the initial switch-on it is necessary to set the lever to the minimum value and perform test heating. After it becomes clear that the device works correctly, you can start testing different temperature modes in ascending order.
• In the course of further use, remember to change the batteries of the electric ignition in time and periodically clean the heater from limescale, carbon deposits and dust.
• If there is no draught in the chimney, the appliance must not be switched on.
• Unlike gas boilers with a closed combustion chamber, the heater cannot be left unattended for a long time. This is dictated by fire safety rules and the peculiarities of the device of open-type burners.
• Unauthorized disassembly of the device and installation of third-party spare parts is prohibited. The boilers can only be repaired by a service center technician or a gas service technician.

Possible causes

The water heater protection system itself shuts off the gas supply when pipes are connected incorrectly, which prevents the heater from turning on. The diagram of the pipe connections is very basic:

The hot water outlet pipe is connected on the right, the gas supply pipe is connected on the left, and the cold water supply pipe is connected in the middle.

Additionally, all gas supply shut-off valves must be checked to ensure they are in the open position. It’s possible that you installed the new equipment and then forgot to turn on one of them. Every tap that has a yellow handle needs to be opened.

The chimney has no or very little draft.

The removal of combustion products through the chimney may be impeded by accumulated soot, building debris, or other foreign objects. This poses a risk to the residents’ lives and health.

Weariness

It is simple to check for drafts in the chimney on your own. Just place a burning match over the inlet hole to accomplish this. If the flame shoots straight down towards the hole, the chimney is operating correctly. If not, you will need to investigate the absence of a draught. As you can see, a common match can assist in fixing a potentially harmful issue and guard against carbon monoxide poisoning in your home.

Verify that nothing is blocking the vent outlet, such as a satellite dish, if there is no draft. In this instance, the issue can be resolved without the need for expert assistance.

You most certainly have chimney fouling if there are no outside factors keeping your chimney from operating correctly. How should I handle this situation? You could, of course, attempt to clean it yourself, but there’s a chance you might break branches from nearby apartments.

Relay sensitivity has increased.

The thermal relay’s heightened sensitivity, which prevents it from overheating and consequently cuts off the gas supply and column, is most likely what caused the malfunction.

Attenuation: an overview of popular models

It is helpful for consumers to be aware of the distinctive illnesses associated with certain water heater brands. Here are a few instances.

Column "Neva 4510"

The gas valve stem is jammed, making it impossible for the spring to push it into the "closed" position.

You must take the water-gas unit apart, unplug the water supply, and use a screwdriver to try to move the stem in order to see if this is the case.

This cannot be fixed; the gas assembly in these boilers is too delicate, so if it takes a lot of force, it needs to be replaced.

Bosch Junkers WR 13-P

The igniter heats the thermocouple, which is the weak point of these water heaters.

After about three years of use, some copies of it quickly develop malfunctions, leading to the column spontaneously extinguishing first, followed by the igniter that cannot be ignited at all and goes out as soon as the button is released.

Usually, scraping the thermocouple with fine sandpaper solves this issue.

Check to see if the igniter tube has moved if that doesn’t help. Since it is not firmly fixed in Junkers, it can be removed with simple cleaning methods, sloppy handling, or even a match. This results in a smaller space between this tube and the nozzle that feeds the gas into it.

And air is drawn into the gas stream through this opening. As a result, the gas-air mixture’s air content drops, which makes the igniter’s flame burn hotter and prevents it from reaching the thermocouple. It is necessary to close this gap. When the igniter is used correctly, the flame will extend and slightly deflect, reaching the thermocouple.

Methods of troubleshooting gas boilers

In Russia, "Vector" gas columns are among the most well-liked. Statistics on sales support this.

The burner does not ignite and no spark appears when the piezo element in the gas column "Vector" is not functioning. The following are the causes of malfunctions:

1. Lack of draught in the chimney. It could simply be clogged and needs to be cleaned out. In the column is a special sensor that monitors the presence of traction. If it is not there, it will not start to operate. If you can not do it yourself, it is better to call a special service.
2. No water pressure. If the water pressure is very good, it affects the diaphragm that presses on the valve. Very weak pressure may indicate a problem with the diaphragm or that the filter is clogged.

1. The feeder is not working. Ignition is done with batteries, without which there will be no current to produce a spark. It is necessary to remove the panel, then take out the battery pack, pull them out and insert new ones.

Expensive alkaloid batteries should be placed in gas columns with electric ignition, like "Amina." Additionally, the ignition electrodes must be positioned correctly in relation to the burner.

1. Oxidation of contacts. Here is nothing complicated, in the block of the column sometimes oxidize contacts. They just need to be cleaned and restarted.
2. Improper regulation. If the piezo does not work, the heater will not start up. Be sure to check the water mechanism regulator. When working well, water should frequently enter the system, and the lever should be positioned in the right position from the edge.
3. The water valve packing is worn out. If you notice that the valve is leaking, then you need to replace the packing gland. If the measure did not help, examine the stem of the microswitch. If it is oxidized, it will need to be cleaned.

If the piezo element in the gas heater "Zanussi" breaks, you can perform the same tasks.

The most common causes of breakdowns are

Now let’s begin reviewing the breakdowns using Oasis and Neva as examples of such basic gas columns. Due to their simplicity, these appliances can be repaired by nearly any man with reasonable hand-eye coordination and tool-handling skills. The following is a brief summary of potential issues and their causes:

• Lack of draught;
• Insufficient water pressure;
• Insufficient gas pressure;
• Non-working ignition system;
• Clogging of the water supply tubes and filter;
• Clogging of the burner;
• Malfunction of the diaphragm or gas block;
• Sloppy mixing of cold water in the mixer;
• Faulty electronics or sensors.

We’ll look at how to get rid of malfunctions and reasons why there’s no ignition now.

Clogs in the system

The instructions for cleaning the strainer are listed above. The heat exchanger system has to be cleaned as well because it accumulates limescale while it is in use. The heat exchanger is taken out and submerged in citric acid-infused water to accomplish this. Heat the solution-containing container on the stove. This solution should also be used to clean the heat exchanger’s interior.

Clogged burners are a common issue with Junkers gas appliances and other comparable units. A significant build-up of soot causes the heater to malfunction in terms of ignition. The burner needs to be cleaned in addition to the heat exchanger. Wash the device’s exterior with a citric acid solution. It is preferable to clean the burner’s interior outside.

When Vector ignition is delayed

Here, too, there are multiple variations. In a situation like this, the first thing to do is open the unit and give it a thorough cleaning, paying particular attention to the nozzles and nozzle jets. If none of the above resolves the issue, the failure’s location should be ascertained by checking the items listed in order:

• electronic ignition unit
• draught sensor
• microswitch
• solenoid valve.

If there is a crackle but no spark when the ignition is turned on, the microswitch needs to be shorted out to ensure it is functional.

Vector microswitch for gas heaters

First, the casing must be removed. To do this, pull the handles toward you and remove them. Then, unscrew the two screws on the right and left sides of the unit’s bottom. Pull the speaker’s bottom in your direction and raise the hood until it emerges from the top pins. Removal of housing. The microswitch is located in the bottom center. The switch button for the hot water tap will be released by the lever and come out of its recessed state when it is turned on; if not, you will need to lubricate with oil and push with a screwdriver. Once all of this is finished, the ignition ought to turn on.

Should this fail to occur, the microswitch must be changed. The solenoid valve malfunctions in this scenario when there is spark and a click, but no ignition. It needs to be replaced as well because it cannot be fixed. It is required to inspect the electronic ignition unit if there is no spark, no crackle, and no clicks, but it is determined that the microswitch is malfunctioning. This unit will need to be replaced because it is difficult to repair.

While some of the aforementioned issues are self-solvable, others result from misuse of the device or disregard for the usage guidelines. In any case, it should be considered that, particularly if the unit does not ignite and the cause is unknown, it is preferable to leave the repair to experts if the malfunction involves gas equipment.

In the realm of home heating and insulation, vector gas columns are a common fixture, but like any appliance, they can face issues. Understanding the possible causes of malfunction and how to repair them is crucial for maintaining a cozy and efficient home. From ignition problems to gas leaks or issues with the thermostat, troubleshooting these columns requires a methodical approach. Checking for gas flow, inspecting the ignition system, and ensuring proper ventilation are some initial steps. Additionally, cleaning the columns regularly and seeking professional assistance for complex issues can prolong their lifespan and keep your home warm and safe. By addressing malfunctions promptly and correctly, homeowners can ensure their vector gas columns operate effectively, contributing to both comfort and energy efficiency in the household.

Overheating

The following are the main causes of overheating most frequently:

1. The user dilutes hot water with cold water. The hot water flow rate is reduced due to the addition of cold water, hence the heat extraction is reduced and the water in the heat exchanger is overheated. Remember: the temperature of hot water can be regulated only by changing its head or with the help of the regulator on the column.
2. The heat exchanger is clogged with limescale at some point. This also results in reduced water consumption with consequent overheating. You can guess what has happened by the obviously weakened pressure of hot water, while the cold water flows correctly. In order to prevent such troubles, the heat exchanger should be periodically washed with special anti-scaling compounds.

In this scenario, the flow rate will decrease with all the associated ramifications if the strainer (strainer) fitted on the water pipe in front of the heater becomes clogged.

Other faults

The following factors can also lead to water heater malfunctions:

Failure of the ignition system

Batteries provide the spark in the columns without electronic ignition; maybe they had time to settle in.

As stated by the manufacturer, battery capacity is not always sufficient for a year.

In other models, a turbine installed in the water pipe activates a piezo element, which generates the spark.

This ignition device is not going to function if the water pressure is low.

When purchasing a column, it is important to consider the minimum water pressure necessary for its proper operation. The igniter in the columns may clog, resulting in a weaker and occasionally yellow flame (which indicates that there is not enough air in the gas-air mixture).

Because of this, it either fails to light the main burner at all or does so only after a significant amount of gas has ignited, causing the heater to light with a distinctive clap. The situation will return to normal after the igniter has been cleaned.

The igniter in columns may clog, resulting in a weak or occasionally yellow flame. This is the result of insufficient air in the gas-air mixture. As a result, the heater either explodes with a distinctive popping sound when it ignites the main burner or does so only after a significant amount of gas has been delivered. The situation returns to normal after the igniter has been cleaned.

The membrane of the water unit has reached the end of its service life

This element, which is composed of polymer material, ought to have enough elasticity, but with time, it becomes stiff and even breaks.

Additionally, lime deposits may cover it.

As a result, even if the user fully opens the tap, the heater will not turn on.

After the diaphragm has been examined, it should be replaced if its state is truly inadequate.

The control module board has burned out

Imported columns are particularly vulnerable to power supply quality, which is why this occurs frequently. Through a stabilizer, they ought to be connected.

It’s also helpful to know that electronic "smart" columns shouldn’t be turned off at night.

3 Different types of gas water heater failures

Water-heating apparatus is by no means new; in fact, the first gas-fired column was created and introduced for sale towards the close of the 1800s. After using these kinds of home appliances for nearly 120 years, consumers have been able to pinpoint the most typical reasons why they break down. The following kinds of malfunctions and failures can happen when the unit is operating:

• The inability to ignite the wick, which is also called the igniter;
• short burning of the lit wick and abrupt shutdown a few minutes after ignition;
• short-lived functioning of the appliance followed by lightning-fast shutdown or gradual fading out;
• smoking of the ignited equipment;
• abnormal functioning of the heating element, which does not heat the water when the tumbler is on.

Application and principle of operation

A gas heater’s primary components are:

• gas burner;
• the heat exchanger above it – a long coiled tube in which the water flowing through it is heated.

Some of the gas column’s auxiliary units are:

1. Ignition device: can be electronic (generates a spark in one way or another) or have the form of a duty burner (igniter or wick), which burns constantly. In old columns, the igniter had to be lit with a match. Modern ones have a piezo element for this purpose, which the user activates by pressing a special button.
2. Water-gas unit: consists of an interconnected diaphragm (installed in the water supply) and a gas valve (installed in the gas path). As soon as the user opens the tap and the water flow begins to move through the heater, the diaphragm flexes and opens the gas valve, thus supplying gas to the burner.
3. Safety automation: consists of several sensors and a special solenoid valve in the gas path, to which these sensors are connected mechanically or electrically. If there is an abnormality in the operation of the heater, the corresponding sensor will close the valve, thus switching off the appliance. In columns with an igniter to this valve is connected to the thermocouple, heated by the flame of the igniter. It is triggered when the duty burner fades out.

An electronic control module is also included in the "advanced" columns.

Possible Cause of Malfunction	Repair Method
Ignition Issues	Check if the pilot light is lit; if not, relight it according to manufacturer instructions.
Gas Supply Problems	Ensure the gas supply valve is open; if closed, open it. If the gas line is blocked, clear the obstruction or call a professional.

Comfort and wellbeing during the winter months depend on keeping your house warm and inviting. Vector gas columns are a well-liked option for heating, but just like any other appliance, they can break down. By being aware of the potential reasons behind these issues and being able to fix them, you can avoid wasting time, money, or discomfort.

Lack of ignition is one of the most frequent problems with vector gas columns. There are several potential causes for this, including a malfunctioning thermocouple, gas valve, or pilot light. First, make sure the pilot light is working properly if your gas column isn’t lighting. Make sure the blue flame is steady and lit. If not, you might have to relight it by following the guidelines provided by the manufacturer. Should the pilot light be ignited, but the column remains unlit, it might be necessary to replace the thermocouple or gas valve.

Inadequate or uneven heating is another common issue. A dirty or clogged burner may be the source of this, as they impede gas flow and reduce heating efficiency. This problem can be avoided with routine burner maintenance and cleaning. Furthermore, look for any obstructions in the flue or air vents, as these can also have an impact on the efficiency of the heating system.

The vector gas column’s gas smells are extremely concerning and need to be handled right away. A gas leak presents a serious risk to public safety and may be indicated by a gas odor. In the event that you smell gas, disconnect the column’s gas supply, open the doors and windows to let fresh air in, and stay away from electrical appliances and open flames. To guarantee safe operation, have the gas column inspected and repaired by a qualified technician.

In conclusion, maintaining a warm and cozy home environment can be aided by being aware of the possible reasons why vector gas columns malfunction as well as the troubleshooting and repair techniques for them. Preventing problems and extending the life of your gas column require routine maintenance, such as cleaning the burner and making sure there is enough ventilation. To guarantee the efficiency and safety of your heating system, don’t be afraid to seek professional assistance if you run into any issues that are beyond your area of expertise.
