The circuit breaker on the brown kettle is out of order. Electric kettle: principle of operation

An electric kettle has become an indispensable attribute of any kitchen and is a sales leader in comparison with other household appliances. This appliance is widely used both at home, in the kitchen and in the office. But unfortunately, like any electrical appliance, the kettle fails after some time of operation. Since the price of this water heater is not too high, it is easier to buy a new one than to repair it. But if you consider yourself a home master, or a device for boiling water is dear to you as a memory, you can try to repair the electric kettle with your own hands.

An electric kettle works on a fairly simple principle, regardless of whether it is an expensive model or a budget one. At the bottom of the device is a heating element connected to a thermostat, consisting of bimetal plate. A tubular heater, when an electric current is applied to it, heats the liquid to a boil. When steam is formed during the boiling process, it passes through a special channel to the thermostat, as a result of which the latter turns off the power supply.

If you look at the scheme of operation of the device, you can see that it works on the principle of an iron, and does not differ in the complexity of the design. But before you repair the electric kettle, there are always difficulties with case disassembly, since the latches (holding the handle) are located differently for different models of units, in addition, the mounting screws can be with a cap for a special screwdriver.

Typical malfunctions

An electric kettle is a simple device, which contains few elements that can fail. However, there are still common problems, among which are the following:

• slow heating of the liquid;
• the device turns off prematurely;
• the kettle does not turn off;
• the device does not turn on;
• burnout of the heating element;
• water is leaking from the body.

Slow heating of the liquid

If you notice that the kettle does not heat water quickly, then pay attention to the condition of the heating element. Thick layer of scale on it, formed due to insufficiently good maintenance of the unit, has poor thermal conductivity, which takes more time to heat the water. If the scale is not removed, the heating element may burn out.

In addition, the entire contact group of the device suffers from overheating, as a result of which the contacts melt or burn.

To get rid of scale, you can use the usual citric acid sold in stores. It is enough to pour 1-2 sachets of citric acid (20 grams each) into the tank, bring it to a boil and leave the heated solution in the tank for 30 minutes. After that, the container must be thoroughly rinsed with running water to remove scale residues. If necessary, the procedure can be repeated.

Device turns off prematurely

This behavior of the electric water heater is explained by the fact that the shutdown of the device may be due to scale formed on the heating element. Since the heating element has a fuse against overheating, it works and breaks the electrical network. To eliminate the malfunction, it is necessary to descale the heaters.

Kettle won't turn off

During the boiling of water in the tank of the apparatus, the steam must be collected under the lid and sent through a special channel to the thermostat. If the lid is not closed tightly, then this does not happen, and the appliance will work without shutting down. If everything is in order with the lid, check that the steam hole, which is located on the side of the handle, is not contaminated with scale. In the case when everything is in order with the hole, it can be assumed that the kettle does not turn off due to thermostat breakdowns.

The thermostat at the electric kettle is located at the bottom of the case, and in order to get to it for replacement, you will have to disassemble the device completely.

For example, a regular budget device was taken, which does not differ in design from more expensive models - an electric kettle Vitek, Tefal, Polaris, Scarlett and others. By the way, in this model, as well as in the Vitek VT-7009(TR) device, the container is made of heat resistant glass. So, let's analyze the unit according to the following algorithm.

1. Kettle repair should begin with unplugging it from the mains. Next, remove the device from the stand (base) and unscrew all the screws located on its bottom panel.
   
   
2. After that, it is necessary with special care to pry off the plastic cover located on the handle using a thin screwdriver. This should be done carefully because in different models of devices, the latches can be located in different places, and they can be easily broken.
   
   
3. After removing the cover, you can see the mounting screws. They also need to be removed.
   
   
4. After unscrewing all the fasteners, applying a little effort, disconnect the handle with the cover from the body.
   
   
5. Next, disconnect the housing from the bottom of the unit.
   
   
6. At the bottom of the case you will see all the main elements of the device: a contact group, a thermal relay and a heating element.
   
   

   

7. pay attention to bimetallic plate(on the right in the picture). If damage is visible on it or it has a worn out appearance, then this may be the reason that the appliance has stopped turning off. The plate is not repaired, but replaced with a new one.

But how to disassemble the Bosch kettle, if when unscrewing all the screws on the bottom, it is not removed? Those who disassembled such a device encountered difficulties that often ended in a breakdown of the device. Since the process is quite difficult to describe, it is better to watch a video on this topic.

The device does not turn on

The reasons why your boiler does not turn on can be different.

1. Faulty electrical cord and plug. To do this, you will need to “ring out” the cord using the tester, touching the probes to the plug contacts and the contacts on the stand (base). If a break is found, replace the cord with a new one.
2. Bad contact in the stand(base). From prolonged operation, the contacts can burn, which is why their conductivity is disturbed. If burns have formed on the contacts, they can be cleaned using fine sandpaper. But in the case when they are melted, they will need to be completely replaced.
3. Faulty internal switch in the device. Since the switch has to experience fairly large loads (from 1500 to 2000 W), its contacts may melt over time. This may cause the machine to not work. The switch is located at the bottom of the handle, and in the event of a malfunction, it looks as shown in the figure below.

In this case, the button must be replaced. But there is a button malfunction, in which you can fix the kettle with your own hands without replacing it. If you look at the button from the side, you can see 2 contacts that close in the “on” position. If on them soot is formed, the device will not turn on.

To remove carbon deposits, you can use fine-grained sandpaper, a nail file, or a thin file. To make it more convenient to do the stripping, you will need a small “refinement” of the button, namely, removing the sides with the help of wire cutters.

Another reason that the device does not want to work can be called malfunction of the mechanical power button. This breakdown is most often found in the Tefal vitesse model, since plastic rails are built into the handle of the appliance, which transmit translational movement from the external button to the internal one located at the bottom of the unit.

After this part breaks, turning on the Tefal kettle becomes impossible. To understand in more detail how to repair an element that has broken, you can watch the video, which discusses one original way to fix a defect.

Heating element burnout

When repairing electric kettles, both old models and newer ones, the most common failure is the burnout of the heating element. The problem with heating elements arises, first of all, due to their overheating due to untimely descaling.

Before repairing a kettle with a disc heater or a heating element in the form of a spiral, it is necessary to disassemble the unit in the manner described above. After that, take the tester and connect the probes of the device to the output contacts of the heater. If the lamp lights up on the device, or it makes a sound, then the heating element can be considered serviceable.

How to check the heating element if no measuring device? It turns out it's very simple. It is necessary to connect zero from the mains to one contact of the heater, and the phase to the other. Next, insert a 220 bulb into the socket, from which 2 insulated wires are removed. Touch one stripped end of the wire to one contact of the heater, and the other to the opposite. If the light is on, then the heating element is working.

If it turns out that the disk heater has burned out, then it cannot be replaced, since it is one with the bottom of the appliance, such as in the Scarlett kettle, or Vitek VT-7009 (TR). Therefore, you will have to buy a new unit. Only open-type heater is subject to replacement.

water flowing

If you notice that water is flowing (leaking) from the reservoir of the device, then it is recommended to use such an apparatus for a while, until scale forms in the microcracks, which can block the leakage of liquid. If this does not help, then you will have to buy a new “boiler” if the warranty period has expired.

Another reason that the reservoir is leaking may be loose connection of the electric heater with the body of the device(if the heating element is open type). In this case, you can tighten the fasteners holding it. If this does not help, then you will have to remove the heating element and change the rubber seal that has worn out.

Thus, we can summarize: in some cases it is quite possible to repair a unit for boiling water on your own. But if you lack certain skills in repairing household appliances, then the best option would be to buy a new kettle. Repair in a service center, from a financial point of view, does not justify itself, and there is no guarantee that the breakdown will not happen again.

Traditional electric kettles are made like those that are installed on gas burners and have a wide bottom with a heater located under it. Electric boilers are made in the form of a jug with a greater height.
The devices require proper handling, as their power is 500-2500 watts. Due to high loads and frequent use, the device sometimes fails, after which it requires repair. The kettle can be repaired without any problems, since the device is quite simple.

Despite the wide variety of models, the principle of operation is the same for all. Water is heated by an electric heater connected to the network. It is inserted through a waterproof seal.

The electric kettle is equipped with a thermostat connected to the power supply and turning off the device when the water boils. It works when a jet of steam enters through a tube or a small hole on a bimetallic plate, which, when heated, bends, pressing the switch.
The device contains thermal fuses that turn off the power in case of overheating due to the lack of water inside or its level falling below the permissible level. The disadvantage is that after cooling, power is again supplied to the heater. In some models, the thermal fuse is connected to a switch that completely turns off the kettle if it overheats.

An indicator LED or a neon light bulb with a load is connected to the external circuit. The presence of an indication is convenient for monitoring the on state of the kettle, as well as turning it off when water boils. In addition, if it lights up and the kettle does not heat up, the cause of the malfunction is immediately clear, which consists in unreliable contact of the electric heater terminals or burnout of its spiral.
The LED is usually used to illuminate water. It is not intended for direct connection to the network and a driver is installed for it.
Electricity to the heater is supplied from the outlet through a cord connected to the power block attached to the case. Cordless devices are often used with pads at the bottom of kettles connected to a base-stand connected to the mains.

Operating rules

Filling your kettle with water is very easy.

It is important to follow the basic rules, the violation of which leads to the failure of the device and accidents.

The kettle is filled only when the power is off or removed from the base. Each device must be marked with a minimum and maximum water level. If they are not, the water must necessarily cover the heater. Underfilling leads to burnout of the heater, and overflowing leads to premature shutdown and splashing of water from the spout.

The procedure for checking and repairing the electrical part

Before starting the repair of the electric kettle, you need to familiarize yourself with the principle of its operation, the device and the circuit diagram of the device. The simplest scheme looks like this:

Determining malfunctions and repairing an electric kettle with your own hands is carried out in the following sequence.

1. 1. In the absence of power, you should first inspect the shield: did it work or. The inclusion of the plug in, the reliability of the contacts and the correct installation of the kettle on the base are checked. Network cord. If the fuse inside the housing blows, it must be replaced.
   2. The stand is disassembled and checked. If the contacts are gone or . If the plastic around the contact group melts, repairs are no longer possible.
   3. The cover of the base is unscrewed and the serviceability of the contacts is checked.
   4. The fastening screws are loosened at the top and bottom of the handle. Then it is removed together with a plastic rocker located above the switch. If the switch is broken, it should be replaced. Often his contacts are oxidized, which should be cleaned. The switch must be disassembled carefully so as not to damage the plastic parts, the LED and the contacts located inside.
   5. The heating element (heater) is tightly pressed to the bottom with a metal disk, and to its ends, on which the cap terminals are put on. Its conclusions for checking the health of the built-in spiral. If it is burned out, the heating element should be replaced. It makes no sense to send a kettle for service repair with a burned-out heater, since it is expensive and, in general, the costs will exceed the price of a new appliance. The heating element is easy to replace with your own hands, and if it is an integral part of the case or it is not on sale, it is better to buy a new kettle.
   6. The kettle does not turn off due to a poorly closed lid or when the steam supply hole is clogged for automatic shutdown. The lid should be tightly closed, but first the kettle is turned off and the water is allowed to cool slightly. If the steam outlet is blocked with lime deposits, it must be cleaned. As soon as boiling stops, the kettle can be removed from the base or the plug can be removed. Another reason for the continuous operation of the kettle is the breakdown of the bimetallic plate or the pusher of the thermoautomatic machine. In this case, the defective part must be replaced.

Descaling

If the kettle turns off without boiling water or takes a long time to heat up, it should be thoroughly cleaned inside from plaque.

So that it does not accumulate in large quantities, the kettle is periodically washed with a patented product. When doing this, make sure that it does not damage the plastic case.
Scale impairs heat transfer from the heater to the water. In this case, the coil overheats and quickly fails.

Important! When purchasing anti-scale products, you should read the instructions for their use.

Common descaling technology:

• the kettle is half filled with water, which should be boiled;
• the plug is removed from and the recommended anti-scale agent is added to the water;
• after the formation of bubbles stops, the water is drained and a new one is poured;
• the water is boiled, then drained and the kettle is thoroughly rinsed.

If a lot of deposits have accumulated, the cleaning procedure is repeated.

The mesh filter is removed and cleaned of scale and other contaminants. If the deposits are not removed, they are soaked in a solution of anti-scale for several hours, after which the filter is washed with water.

Eliminating leaking kettle

If a new kettle has leaked, you can wait a while for the scale to fill the microcracks. If the warranty is still valid, the device should be taken to a service center.
Leaks can be caused by cracks. In this case, repairing the kettle will not work: you need to buy a new one.
The heating element may have loose fasteners. Leakage is eliminated by tightening nuts or screws.
Leakage occurs as a result of damage or aging of the gasket, which must be replaced. The use of sealants does not help here.

Question: how to repair an electric kettle in case of breakage of some parts that are not on sale, usually solved by buying a new appliance.

Some kettles contain a level indicator in the form of a transparent plastic tube. If cracks appear in it or it is broken at the junction with the kettle, the hole must be plugged with a screw with a nut, washers and a seal. Such a repair spoils the appearance of the device, but you can boil water in it. It is necessary to use a cap made of stainless steel or with an anti-corrosion metal coating.
To check for leaks, the kettle is filled with water and placed on a paper towel.

Conclusion

An electric kettle is a device for quickly boiling water. Despite the simplicity of design and electrical circuit, it has a high power and often requires repairs. The kettle can be restored with your own hands, if you know its principle of operation and the causes of malfunctions.

The issue of sending electric kettles for repair is decided after receiving the conclusion of the service department. But is it worth spending time communicating with specialists if it is possible to solve the problem on your own? The device of a household appliance is not as complicated as it seems. After studying the main components, the principle of their operation, possible malfunctions, the restoration of the electric kettle will be within the power of home craftsmen.

Before you start diagnosing, repairing a household kettle, you will need to find out what components it consists of, how it works. Despite the abundance of offers under different brands, all electrical appliances in this category have a similar device. They include the following parts:

• frame;
• power indicator;
• a heating element;
• control system (power button, thermostat);
• stand with power cord and contact group.

Connections in the internal communication circuit are carried out by means of captive terminals, less often by soldering. After installing the kettle filled with water on the stand and pressing the key, the supply circuits of the device are closed. This is accompanied by a light indication signaling that everything is working. If at this stage there is no contact between the stand and the bottom of the device, the switch is faulty, nothing will work.

Further, the heating element (spiral or disk) installed in the lower part gradually brings the water in the tank to a boil. After boiling, the automation turns off the power to the heater (the light goes out with a characteristic click). If there is not enough water in the kettle or it was accidentally turned on empty, the protection system should also work, de-energizing the power circuits.

The device of the nodes of the electric kettle

Both the old models with spiral heating elements, and the new ones with disc-shaped ones, remain similar in terms of the principle of operation, the presence of the main nodes. They will definitely have a heating element, a power button and a protection unit. Without them, the kettle will not work.

Overheat protection system

This node is necessary to ensure fire safety requirements. If it were not there, then with an insufficient water level, the inclusion of an empty kettle would certainly have caught fire. And so a special contact group will de-energize the heating element.

As a working tool, a special plate of 2 metals is used for it, which reacts to heating. The normal position is closed, when overheated, the bimetal deforms, breaks the power circuit, turning off the heating element. Manufacturers of household appliances use a number of standard solutions for this unit. And all use bimetal sensors, reliable and efficient.

The only drawback of thermal protection is the need to wait until the working part cools down and takes its original position. After that, the kettle is ready for use again.

Automatic shutdown system when water boils

Another critical node, without which the normal operation of the kettle is impossible. The procedure, which is so accustomed to that they do not pay attention, is the automatic shutdown of the device after heating the water. It is not by chance that manufacturers focus on pouring liquid into the flask to a clearly marked level (corresponding to the nominal capacity) in the operating instructions. The operation of the auto switch under the action of a jet of steam depends on this.

At the heart of protection is another bimetallic group, which, when heated, breaks the power supply circuit of the heating element of the kettle.

Power on indication and backlight

Each model has a power indicator light: without it, it is difficult to determine the status of the device. This is a light bulb interlocked with the contacts of the "main" button. The backlight is optional. Some manufacturers include it as an option. It works synchronously with the inclusion (switching off) of the kettle.

How to repair with your own hands

Before you seriously start repairing the kettle, you need to understand the probable causes of the malfunction, moving from the consequences. There are several of them:

1. The device turns on, but the water boiling sensor does not work.
2. It is impossible to press the power button of the device.
3. The indicator lights up, nothing else happens.

Each situation requires detailed consideration, since the scatter of causes is in the field from poor contact to a burned-out heating element. And not all of them can be eliminated on their own. But first, you will need, armed with a screwdriver, to carefully disassemble the kettle without damaging it.

How to disassemble

You will need a screwdriver, usually a flat or Phillips head. In rare cases, the manufacturer uses non-standard solutions for which it is not so easy to find a tool (trihedral recess).

If the kettle has a stand, it is immediately put aside, and water is poured out of the appliance itself.

Next, unscrew the screws that secure the parts of the plastic case. They can hide under decorative overlays. In combination with fastening on self-tapping screws, latches are used. It is very important not to destroy them when disassembling the kettle.

If the appliance does not heat water, but the light is on

You don’t need to be a major electrical engineer to understand: the kettle is powered from the mains, but then something interferes with normal operation. This remains to be seen by examining the components of the device.

It often happens that the overhead contacts of the heating element have weakened (oxidized), there has been a break in the conductors. Rarely does the heater fail. If the heating element is embedded in the bottom of the kettle (and burned out), you will have to forget about the restoration.

Restoring contact in the slip-on terminals

It is difficult to visually calculate this malfunction. Having reached the heating element of the kettle, slightly tugging at the terminals, check the reliability of the contacts. If necessary, carefully bend the edges, trying not to damage the insulation and the wire itself. Do this with a de-energized, disconnected from the network device.

Another clear sign of trouble with the terminals is traces of a short circuit, soot, molten insulation, burnout of the contact plate. Depending on the level of skill, they use methods for restoring (replacing) the terminals, cleaning with fine sandpaper.

Repair of welded contacts

If a break occurs at the place of welding, it will not work to restore their integrity at home. It is necessary to choose one of the repair options: soldering, mechanical connection. The chosen method should ensure reliable operation of the kettle for a long period, so it is better to carefully consider what exactly to give preference to.

Does not heat water, indicator does not light

It seems that the answer is simple: in this situation, the device does not receive electricity. But what exactly is the reason for this “behavior” - a faulty socket (plug), poor contact between the kettle and the stand, failure of the switch - and we have to figure it out.

Contact group repair

Most modern kettles are arranged in the same way: a base-stand connected to the network, and the device itself. The weak point of this design is the contact group through which electric current is transmitted to the kettle. If water, dirt gets on the metal, it oxidizes - the work will become unstable. Usually the problem is solved by wiping the contacts on the bottom and stand, less often by cleaning with fine sandpaper. In the most difficult situations, individual elements will have to be replaced.

If the question was precisely in this malfunction, then after its elimination, the kettle will start working without any complaints.

How to fix a switch button

In the practice of using kettles, there are also situations when the plastic button "falls" into the body parts. Repair is not always possible, since it will require the craftsman to have the skills to work with plastic, metal, as well as an understanding of what and where to restore. This is the key axis or counterpart.

Switch repair

The switch fails for various reasons: marriage, operating conditions, initially low quality of the assembly (in cheap models). According to common circuitry, the switch block itself is placed in the handle (top) or at the bottom of the kettle.

Accordingly, when the power button is pressed, control is transferred directly to the electrical device or to it, but through the pushers.

The switch accounts for a significant proportion of failures in the operation of kettles: a bimetallic plate is built into it, a large electric current acts. Sometimes it is sufficient to gently clean slightly burnt contacts with an ear stick moistened with alcohol, fine sandpaper.

Premature shutdown of the kettle

If the device works, and then abruptly turns off, the problem is in the automation. This is a failure of overheating protection, poor contact, oxidation of the bimetallic plate. Consistently check all components, looking for a problem area.

How to fix a water leak

Drips on the body, thin streams of water are signs of a violation of the tightness of the kettle flask. And then it is necessary to localize the leak, determine how expedient it is to eliminate it, and proceed with the repair.

Where can it form

Most often, leaks are detected at the joints, along the seam between the bottom and the cylindrical part, on the pasting of the measured transparent insert.

At the junction of the measuring window with the body

You can try to repair the defect with silicone sealant. The complexity of the situation lies in the fact that the selected adhesive will be in contact with water, therefore it must be neutral, harmless to humans.

Crack in the plastic body

The destruction of the case, which is made of heat-resistant, durable plastic, is practically unrecoverable. Unfortunately, you will have to buy a new kettle, because the crack will expand.

The place of docking of the metal bottom-disk with the flask of the kettle

It is found in devices with a glass flask. In rare cases, the destruction of the metal due to corrosion. We can recommend soldering or sealing the joint with silicone.

The choice of sealant for gluing

Silicone must comply with sanitary standards, withstand high temperatures, and not visually stand out against the background of the case. It is known from practice that you can use a regular sealant, only after it hardens, you need to change the water in the kettle several times before drinking it.

Gluing parts

Before gluing, the old silicone is removed, the contact surfaces are cleaned, and degreasing is carried out. The sealant is applied in a thin layer so that air bubbles do not form. Excess silicone from the connected parts is carefully removed with a damp cloth.

Leak test

After the silicone has solidified, a leak test is carried out: water is poured into the flask and the kettle body is carefully examined. There should be no leaks.

How to clean rust

Unaesthetic plaque on the walls, the bottom of the kettle can be eliminated with citric acid. It is enough to fill the flask for a few minutes, then rinse it.

Replacing the spiral heating element

If the spiral heating element, which was installed in the old models of kettles, broke (burned out), it is easy to replace it. But first you need to make sure that the problem is in it.

Disc Heater Replacement

The disc heater located in the bottom of the appliance (not to be confused with the stand that modern kettles are equipped with) cannot be repaired. Depending on the design, it is permissible to replace it with a new one.

How to connect directly

This type of switching is used when checking the heating element, when all other nodes of the kettle are excluded from the diagnostics. To do this, it is necessary to fix the contact terminals on the network wire, then insulating the installation sites. Next, the plug is inserted into the outlet, the kettle should start working. This method is not recommended for long-term use of the device due to its unsafety.

When can I return to the store

Return to the distribution network is possible if the seals are preserved, there are no traces of opening the kettle, and also during the warranty period. When contacting the store, the buyer presents the instruction manual with the completed warranty card and the faulty device itself.

Operating rules

The kettle must not be dropped, used for other purposes, operated in ways not provided for in the instructions. Do not turn on the device with a faulty mains plug, damaged insulation - this can be life-threatening.

Repair of electric kettles from A to Z and 7 ways to determine the breakdown

Repair of electric kettles is required quite often Buying any electrical equipment, you will never guess the term of its operation. An electric kettle is one of the household appliances that is used to the maximum in the household and sooner or later it may break down. But it is important to be fully prepared and, if a breakdown is detected, do not run to the store for a new device, but try to independently identify the cause and, if possible, eliminate it - this is real. And how exactly to safely and easily eliminate the breakdown of the electric kettle will be described later.

Search for the cause and repair of kettles

Repairing electric kettles is a fairly simple procedure that you can handle with your own hands. When repairing a kettle, it is very important to know how to find a breakdown and how to safely repair it. Often the failures of all kettles are the same: either it does not heat the water or it simply does not turn on.

Since many teapots are now imported from China, the durability of their work leaves much to be desired. Breakdowns are less common in Bosch kettles.

Repairing electric kettles can sometimes be a very exciting experience. For example: if the handle with the lid is one-piece and attaching them separately outside the kettle does not work, because the bolts on which it is all attached are glued near the edge of the door. Even many experienced craftsmen think, how did the Chinese collect all this?

Repairing an electric kettle can be a fun activity

The scheme for searching for the cause of a breakdown in electric kettles:

1. Before you fix the device, you need to investigate the mechanism of its operation. There are a lot of manufacturers of electric kettles, but they are all assembled according to the same principle: through the socket into the kettle, the contact group (the thermostat located in the spiral base of the kettle) with the help of which the water is heated transmits voltage.
2. Be sure to make sure that it is disconnected from the power supply before disassembling the device.
3. It is necessary to check the integrity of the contacts near the heating coil of the kettle.
4. Boiling with the lid open can cause the kettle to break down, as a result of which the plate in which the heating element is installed does not bend and damages the highly heated heating element. As a result of such a breakdown, the thermostat will have to be replaced.
5. To repair a Tefal kettle that does not turn on, it is necessary to clean the heating element (which is hidden behind the disc element) from scale with a special descaler.
6. If the kettle button does not work, then this may mean a breakdown of the thermostat or resistor (5w12kj), which is responsible for the operation of the heating circuits.
7. When the electric kettle stops heating, it is necessary to free it from water, then turn it over, first disconnecting it from electricity and turn on the switch on the stand, which is represented by a button.

If the contacts connecting the thermostat to the electrical plug are broken, they must be connected and sealed with insulating tape.

Do-it-yourself electric kettle repair

The principle of operation of the electric kettle is the electric heating element. The bimetal plate is responsible for the release of steam, which heats the water and automatically turns off when the water boils in the kettle. But what to do if the kettle breaks? In the past, a broken kettle caused many problems, but in modern times, it is not difficult to eliminate this problem.

If a new kettle leaks, it is not necessary to replace it with a new one. You can wait a few weeks until scale forms on its bottom, which will cover all the cracks inside. If the kettle drips heavily, then you need to contact the service center.

If the kettle is broken, you can repair it yourself

Basic rules for do-it-yourself teapot troubleshooting:

1. If the kettle is leaking, the case may be defective. To eliminate water leakage from the kettle, you can use a special sealant and glue to seal microcracks.
2. It also happens that the kettle has not yet boiled, but the light has already turned off. To do this, it is not necessary to know how the principle of operation works, but just to clean it from scale. This problem is often found in Scarlett and Polaris kettles, and Braun and Maxwell kettles have a self-cleaning and filtering system.
3. If the kettle light is not on, then it is necessary to clean the contacts inside the kettle, which could be oxidized.
4. If the kettle does not work, it must be directly connected to the network and make sure that the outlet is working.
5. The electrical circuit of the kettle is quite simple and similar to the operation of the iron. There are not many parts in the kettle that can break. In the event of a breakdown, first of all, it is necessary to deal with the heater, which is usually changed to a new one.

If the kettle does not heat, then it is necessary to look for the direct cause of the breakdown in faulty contacts.

Electric kettle diagram

The device of the electric kettle circuit, as in any heating element, is quite simple. Any electric kettle has a heating element and a thermal switch - these are the main working mechanisms. Electric current enters the heating element, and heat is transferred from the spiral to the heating element, the water heats up, and the kettle automatically turns off.

It is very important to pour water into the kettle not higher than the maximum mark, otherwise, when boiling, it will spill, and not lower than the minimum, otherwise, if the heating element boils, it may fail and you will have to change it. Kettles Brown and Bosch have a unique system of protection against such damage.

Electric kettle diagram

Electric kettle scheme:

Electric kettles have long and firmly entered the lives of modern people. They are used not only in offices, but also at home, gradually replacing the classic kettles of conventional design. Despite the huge variety of models, each electric kettle has a common principle of operation.

The principle of operation of electric kettles

For the manufacture of modern electric kettles, heat-resistant plastic or stainless steel is most often used. Most models are equipped with an automatic shutdown function.

All work of the electric kettle is based on heating water placed in a special flask. The heating process itself is carried out by a heating element fixed to the body in various ways. If the fasteners are damaged, a water leakage problem may occur.

In most modern electric kettles, disc heating elements are installed. When water boils, steam comes into contact through a small hole with a bimetallic element. As a result, the plate bends and acts on the switch. In some models, there is a special protection that works and turns off the electric kettle in case of complete boiling of water. The water level in the kettle is controlled by an indicator.

In order to keep warm as long as possible, many designs of kettles use the principle of a thermos. In this case, not only the heating of the water in the flask takes place, but also the subsequent maintenance of its constant temperature. This is especially true for large families where hot water is constantly required.

Operating rules

In order to properly operate the electric kettle, you need to know that each appliance has a built-in electric heater, the power of which is 1.5-2.3 kW. The speed of boiling water depends on the power of the heating element.

Proper filling of the device with water contributes to the increase in the service life of the device. Before pouring, the kettle must be disconnected from the mains or removed from the stand. It is necessary to ensure that the water level is optimal, without overflow and underfilling.
