Do-it-yourself repair of geysers "Vector Lux": common breakdowns + tips for fixing them

What else can be done?

• To increase the temperature of the water flowing from the tap, you can do the following: turn the knob all the way to the right, then open the water tap only halfway. Since the movement of water will slow down, it will warm up better.
• It will not be superfluous to check the pressure in the gas pipes or in the cylinder. But you should not do it yourself - it is better to seek help from professionals.
• The water can stay cool if the faucet adds cold water to the already heated one. Compare (by touch) the temperature of the tap water with the temperature of the outlet hose. If the water is colder, then the problem is in the faucet.
• If the temperature of the water from the tap “jumps” all the time, and the geyser itself periodically turns off, the mixer or filter may be clogged.All these elements, as well as the shower head, should be checked from time to time for lime and rust deposits.

Other malfunctions of flow heaters

In addition to the problems listed above, speaker owners have to deal with the following problems:

• weak sparking, sometimes single discharges slip, the gas does not flare up;
• ignition is accompanied by strong cotton;
• after closing the DHW valve, the burner continues to work until the electromagnet cuts off the fuel supply due to strong heating (at the command of the sensor);
• spontaneous ignition after connecting to a power source;
• insufficient heating;
• water is flowing from the water heater.

Problems with sparking give rise to pops - gas has time to accumulate in the combustion chamber before a sufficiently powerful discharge is formed. If the spark remains weak, the fuel-air mixture ignites when it reaches a high concentration, which is accompanied by a micro-explosion. There have been cases when pops damaged the heat exchanger, violated the seals and the normal contact in the electrical circuits of the sensors.

Traction violation

If there is no stable thrust, then the product simply cannot function normally - there is no ventilation, the flame goes out due to lack of oxygen. The new models are equipped with thrust sensor

, which controls the exhaust of combustion products - if it is absent, then the gas does not ignite. This method is used to protect the product.

Advice! The easiest way to check for draft is to bring a lit match to the technological hole on the front panel of the gas column. If the flame deviates into the product, then the thrust is normal.

When the draft does not work, it is necessary to inspect the chimney, but the user himself can only check the collector that goes to the wall - then the sphere of specialists in the maintenance of ventilation and chimneys, you need to call the city service.

Lineup of geysers Vector

Speaking of geysers Vector, the following models can be noted.

1. JSD This model became popular a few years ago. First of all, the great demand is due to the low price for such devices, which is set within 4,000 rubles. It is also worth noting the convenient small size. Such a gas water heater can be used even in a small room. Equipping with a digital display has greatly simplified the procedure for use, as well as automatic ignition. Geyser Vektor JSD 20 is available in several colors: white, gold and silver.

2. JSD 11-N is a great solution for small spaces. It is ideal for installation and use in the kitchen or small bathroom. There is an automatic flame extinction sensor and protection against overheating of the heat exchanger.

3. To date, the company has decided to go further and has developed a new gas column model called Lux ​​Eco. This variant is equipped with the same features as previous models, and also has an improved security system, which reduces the risk of overheating of the device. The combustion chamber in this device is water-cooled. The Vector Lux water heater control system allows you to independently adjust and set the desired temperature, there is a digital display. These models are designed taking into account possible pressure drops in the water main.The outer case has a beautiful outer mirror surface with different patterns, it looks very neat and stylish. A water heater of this model has a standard package: the gas column device itself, flexible pipes, fasteners, a faucet, a shower head, instructions.

In the budget price category geysers Vector - This is the best option for instantaneous water heaters. They are easy to operate, have a good security system and stylish design. Since not the highest quality Chinese components are used for production (which can significantly reduce the price of this equipment), the service life without repair is not very long. In any case, it will not be difficult to find components for restoring the efficiency of the gas column.

First aid

Before looking for a breakdown and calling the wizard, check that all the conditions for the normal operation of the column are met.

What to look for:

• If the water is not heated enough, check the temperature regulator and, if necessary, tighten it to the desired value;
• If the device is working at maximum, the pressure is very good, but you need to make the water hot, open the tap halfway;
• Check that the gas supply valve is fully open, especially if you have recently turned off the gas due to repairs or departure;
• If the column operates on liquid gas, call the master to inspect the cylinder and check its serviceability;
• Check if cold water is turned on somewhere;
• Compare the temperature of the hose at the dispenser and mixer. If it is different, the tap must be cleaned;
• Check if the filters are clogged.

If all of the above is in order, and the water heating system still works poorly, you need to look for a breakdown in the device itself.

Advantages of water heaters "Vector"

The technique has several advantages, which made it very popular among Russian buyers.

Price

Not everyone can spend more than 10 thousand rudders on such a device, and it is quite difficult to do without it in a country house or in a private house. The brand "Vector" does not have models more expensive than 4 thousand rubles - despite this, the equipment is quite high-quality and versatile.

Design

The equipment looks stylish and discreet. The column will not attract attention, and sometimes even emphasize the interior. The manufacturer also took care of the compact dimensions of the equipment. In the event of a breakdown, the owner can always find the necessary spare parts that will be inexpensive and extend the life of the device.

Control

All models are equipped with a simple and convenient control system. It consists of two switches. The first regulates the gas supply, and the second is responsible for the amount of water entering the heat exchanger. There is also a technique with a third switch for the Winter/Summer function. The first program activates all sections of the burner. The “Summer” program, on the contrary, turns off some of the sections - a plus for savings.

Kinds

To date, the market for gas appliances presents a wide selection of different models of gas burners. If we take, in general, then all gas heaters work on the same principle and differ from each other in the following characteristics.

Power. The greater the power of the heater, the more water it can heat in a short period of time.

Among the massively common types of power, the following three can be noted:

1. Heater with a power of 28 kW.
2. Heater with a power of 26 kW.
3. Heater with a power of 17 kW.

The latter type has a low cost, but at the same time it cannot provide hot water to the bathroom and kitchen at the same time. As a rule, most users choose the second type, as it has an optimal price-performance ratio.

The safety of the device. It is one of the main criteria when choosing a heater. Despite advanced technologies, there are still cases when water or gas is turned off and, in order to prevent leakage of fuel or combustion products, the columns are equipped with the following sensors.

1. Gas shutdown sensor, in case the flame goes out.
2. Flame sensor. It is redundant and also turns off the gas supply if the flame goes out and the first sensor does not work.
3. Water pressure relief valve. Prevents the column water pipes from bursting in case of high pressure in the system.
4. Sensor for opening and closing a water tap. Performs the function of turning the heater on and off when the tap is opened.
5. Traction sensor. Prevents the column from turning on in the absence of traction, while avoiding carbon monoxide poisoning.
6. Water pressure sensor. Prevents turning on the heater in case of low pressure in the water supply.
7. Thermostat. Provides shutdown of water heating when the temperature has reached the desired level.

This is the main list of protective sensors that a modern geyser should be equipped with. In the absence of one of them, such a device is highly discouraged from a safety point of view.

Kind of arson. Arson can be carried out in one of two ways.

1. Piezo refers to the mechanical form, that is, you have to set it on fire manually.
2. The auto igniter is battery operated and is automatic. The principle of operation is the same as in piezo arson, only without human intervention. Also, automatic ignition includes hydroturbine ignition, powered by an electric generator.

Additional features. These features include the presence of an LCD display that displays various information, additional settings, etc.

This is the main list of differences that distinguishes the types of geysers from each other, they also have differences in color, shape and design, which is no longer so significant when choosing and does not affect the technical characteristics.

Root Causes of Problems and How to Fix Them

For those who wish to purchase a Vector gas water heater, there is a useful bonus. It consists in the presence of such a service as a service. In the event of a breakdown of the water heater, its repair will be carried out by a qualified master in the shortest possible time. This will be facilitated by the absence of difficulties in acquiring spare parts, the price of which is quite reasonable.

Gas column problems Vector may be as follows:

1. Discoloration of the flame and the presence of traces of soot. A similar phenomenon indicates that the device urgently needs to be cleaned. Of course, this problem cannot be unexpected, because the cleaning of the water heater from dust should occur regularly. Otherwise, violations in his work are inevitable.
2. Lack of temperature data. Usually they are displayed. If this does not happen, then damage to the screen itself or the circuit through which the necessary information reaches it is implied.
3. No response to activation. This can happen due to low water pressure (if there is a spark).To solve the problem, clean the filter located at the inlet to the water heater or the heat exchanger. In the first case, the cause of pollution will be dust, and in the second case, scale. If there is no spark, just replace the batteries.
4. Reduction of the flame up to its complete disappearance. This fact indicates the need to change the membrane of the water node.
5. Spontaneous switching on and off of the device. In this case, it will be necessary to clean the chimney, check the sealing of the pipe and air duct, and eliminate the causes of overheating of the Vector column.
6. No spark when batteries were recently changed. This will require the replacement of defective parts, in particular, a microswitch, a solenoid valve and (or) an electronic control unit.
7. Reducing the pressure of the liquid at the outlet of the column. This can happen due to the lack of normal pressure in the entire system, the small diameter of the pipe and the clogging of the water filter.
8. Insufficient water heating. In such a situation, only cleaning the heat exchanger tubes from scale and dust will help.

Self-repair should occur only with such experience. If it is not there, you should definitely call a specialist, and not try to fix everything yourself. Such recklessness is fraught with an explosion or spontaneous combustion.

According to experts, the likelihood of the problems described above appears due to the poor quality of the parts that make up the water heater, the lack of automatic maintenance of the required temperature regime, the insufficient thickness of the heat exchanger walls and the power of the apparatus.

Disadvantages of water heaters "Vector"

Do not think that for modest money you will purchase newfangled equipment that will last for decades - this is not so. You need to understand that budget options are not designed for long-term use and cannot offer innovative technologies that are present in expensive counterparts. It happens that after a season of use, equipment needs repair and replacement of parts.

Another disadvantage is the burnout of the heat exchanger. Although it is made of copper, its layer is quite thin. Therefore, over time, the heat exchanger can no longer withstand high temperatures and the equipment breaks down.

Even these shortcomings do not stop buyers and heaters are actively sold. Someone believes that they are much better and better than models from a more expensive segment. In any case, it is impossible to say for sure about the quality without testing the water heater yourself.

The geyser goes out

The geyser goes out

If the heater turns on but goes out, the problem in most situations is the bimetal temperature sensor, which is necessary to protect the equipment from overheating. Also, due to malfunctions of this element, the heater may not turn on at all.

This problem has 2 main development scenarios.

1. According to the first scenario, the burner lights up properly, the equipment functions for some time without any complaints, and then it goes out and does not show any signs of life for some time - attempts to ignite the heater do not lead to anything. Usually after 20-30 minutes the equipment turns on again and history repeats itself. This is due to the excessive sensitivity of the sensor. As a rule, it is "innate", i.e. This is a factory marriage.Doing something on your own is extremely difficult. It is better to immediately contact the manufacturer's service for warranty repairs.
2. In accordance with the second scenario, the column may turn off randomly, and sometimes not turn on at all. The reason, as a rule, is the wear of the insulating material of the conductor of the bimetallic sensor. There is a banal short circuit to the case, as a result of which the safety valve is activated, and the column begins to behave abnormally.

Heat exchanger clogged with scale

With our water quality, heat exchangers in gas water heaters become clogged with scale quite quickly and very much, which reduces their thermal conductivity and increases gas consumption.

The longest, in terms of time, process is cleaning the main tube (radiator) from deposits that occur when tap water is heated. If you turn the gas knob to the end, and the water coming out is barely warm, then this indicates that the heat exchanger is clogged with ordinary scale, which does not transfer heat well.

This happens quite often if the geyser is without auto-ignition (with an igniter). Also, scale is formed if you set the water heating temperature too high. The unit overheats, the tube (radiator) heats up to 80-850, which contributes to the rapid (a little over an hour) scale formation. Isn't it better to just turn off the column in time? Then there will be no problems, because 40-600 is enough for all washing and washing processes.

Before starting work on the heat exchanger, check the inlet cock or valve. Maybe the whole reason is in their clogging. But if they are serviceable, it is necessary to get rid of deposits in the tube.

There are two ways to solve the problem with scale. We will consider both options.

Auto

The Cillit KalkEx cleaning system does the job pretty well. With its help, you can quickly clean any boilers from scale. Unfortunately, it is not very accessible to ordinary users of gas water heaters.

This is an expensive method using a special device (Cillit KalkEx) and a set of special flushing preparations. Your column does not even need to be removed from the wall. Just need to disconnect the water hoses for water (inlet/outlet).

The cleaning device is connected to the column, and it drives the heated reagents in a closed cycle (in a circle). Scale under their action decomposes, is washed out and merges.

Manual

Cheap, but long and laborious process. For its implementation, it is necessary to disassemble the water heater almost completely and then rinse it manually.

The following materials and tools will help us with this:

• wrenches (set);
• screwdrivers (phillips and regular);
• paronite gaskets (set);
• rubber hose;
• vinegar essence or antiscale agent.

Disassembly of the gas apparatus

To remove the heat exchanger proceed as follows:

• first block the access of cold water;
• then we remove the external elements that prevent disassembly (knobs of switches, regulators);
• remove the casing, and for this we unscrew the screws located on the rear wall of the unit, lift and remove the cover;
• open the "hot" tap;
• unscrew the supply tube from the heat exchanger and move it away;

Flushing the system

After the water has completely drained, we put the hose on the heat exchanger tube and raise it above the level of the column.Slowly pour the solution we prepared into the hose and leave the column for 4-6 hours.

Next, you need to slightly open the water supply tap and observe the water that will come out of the column, if you see a lot of scale, then our work was not in vain - we got rid of it. If there is no scale in the outgoing water, then we repeat the whole process again.

How to install and configure?

After purchasing a gas column, you should take care of its proper installation. The procedure for connecting the device to the highway must be carried out in accordance with the standards and requirements, so it is worth entrusting the work to professionals. Installation in the apartment can be done independently. After purchasing the equipment, you must act strictly according to the instructions, because working with gas equipment is quite dangerous. It is also necessary to order project documentation, and while the design is being carried out, it is worth buying spare parts for work:

• connecting chimney metal pipe;
• pipes and fittings for water and gas wiring;
• stop valves;
• fasteners to hang the device on the wall;
• galvanized steel sheet if needed.

Hanging the unit on the wall does not require much effort, the main thing is not to break the distance to household items. After the process of attaching to the wall, it is necessary to connect the column to the water supply. For this, the following actions are performed:

• using fittings, pipes are connected to the water supply and column;
• to connect the device, it is worth using American women;
• pipes must be fixed to the wall to avoid overloading the nozzle;
• the sump is mounted on the input wiring horizontally and mounted on the wall;
• faucets must be installed on the piping.

After completing all of the above work, it is necessary to connect the gas pipe to the column. This requires the help of skilled workers in the industry. They must install the column to the gas line and pre-configure the equipment. It remains for the user to make the initial launch of the column.

To do this, both taps of the water supply are opened, and then hot water on the mixer. You should wait until the water jet is leveled, and then turn off the mixer. Next, you need to insert the batteries into a special compartment and open the gas valve. If the installation of the Vektor equipment was carried out in compliance with all the rules, then after the hot water is opened, the device will automatically start. The homeowner will only need to adjust the optimum outlet temperature.
