Electric kettle connection diagram. How to connect an electric kettle directly. Where can it form

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.

Electric kettle repair

Although there is now a fairly large selection of household electrical appliances, do-it-yourself electric kettle repair can be useful for those who have temporary financial difficulties or the old kettle is very convenient for you, you are used to it. It may also be that someone asked you to fix the device, or you are just an inquisitive person and you want to do everything yourself.

The principle of operation of the electric kettle

The principle of operation of an electric kettle is quite simple, and its device, even in expensive models, is not original. The heating element in the lower part, when electricity is supplied, heats the water. The heating element is connected to a thermostat (bimetallic plates), and as soon as the temperature reaches the set value, the kettle is disconnected from the network.

For ease of use, I include an LED light bulb with a load in the external circuit of the circuit. When the circuit is closed, the light is on, otherwise it is not. The electric heating device must necessarily include a thermal fuse that opens the circuit when overheated. It is needed in case you, for example, forgot to pour water into the kettle.

As you can see, the circuit diagram of an electric kettle is similar to that of an iron, and is not very complicated in itself. In fact, there are quite a few parts in the device that can break. The most difficult part is the thermostat, the device of which depends on the specific model. But in the event of a breakdown, they do not repair it, but change it to a new one.

Repair sequence

If the electric kettle is broken, then first you need to check the cord with the stand, making sure that the voltage is supplied to the kettle. Do this by ringing the contacts with a multimeter. Try to disassemble the burned-out stand and solder the contacts, but if the contact group has melted, then it will not be possible to repair it.
If everything is in order with the cord and stand, then the next step is to check the ring contacts on the kettle itself, after pressing the on button. Most likely, there will be no signal, so you need to unscrew the bottom part and check all the contacts already inside to find out what specifically does not work. A non-working coil or temperature sensor must be replaced.
Next, check the automatic shutdown button located on the handle. It quite often fails because the contacts are oxidized. They must be cleaned with sandpaper, and the device will work normally.

In a modern kettle, the device is such that it is most difficult to get to the on-off button in order to fix it. To do this, you will have to remove the cover and unscrew the bolts at the top and bottom of the handle. This must be done carefully, as plastic parts break easily. If the LED bulb does not glow, then it is also changed.

Can a kettle be repaired if it's leaking?

Many are interested in the question of what to do if the electric kettle is dripping. Throw it away or can it be repaired? The cause of the leak may be a cracked housing or a worn seal. In the first case, it is best to go shopping for a new kettle, and in the second case, you can try to fix it by replacing the O-ring on the heating element. It does not make sense to glue the place of leakage in the region of the measuring scale, using various sealants.

If a new kettle drips just a little, you can wait a while (a week or two). It is possible that scale is formed, which will tighten the microcracks. A kettle whose warranty has not yet ended and has leaked should be taken to a service center.

In order to keep the electric kettle from dripping for as long as possible, it is advised to descale it regularly, and if possible use soft, filtered water. In this case, the heating element will work better, and the sealing rubber will last longer.

Premature Shutdown

It happens that the kettle turns off ahead of time - it has not yet boiled, but has already turned off. In this case, it makes no sense to disassemble the device completely. You just need to clean the scale. You can do this, as you probably know, with the help of citric acid. A small bag of lemons is dissolved in half a liter of water and the kettle is turned on with an open lid. If necessary, the procedure can be repeated.

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.

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?

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

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.
Be sure to make sure that it is disconnected from the power supply before disassembling the device.
It is necessary to check the integrity of the contacts near the heating coil of the kettle.
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.
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.
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.
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.

Basic rules for do-it-yourself teapot troubleshooting:

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.
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.
If the kettle light is not on, then it is necessary to clean the contacts inside the kettle, which could be oxidized.
If the kettle does not work, it must be directly connected to the network and make sure that the outlet is working.
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.

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.

The main element of the electric kettle is the heating element, which is responsible for the heating capacity of the kettle, it is located under the metal plate of the kettle. If this element stops heating, it should be replaced.
Inside the heating element there is a network spiral, which heats up and supplies heat. Why does the spiral supply heat to the heating element? due to electrical resistance. Its replacement in the event of a breakdown is also not difficult.
The button for turning on the kettle is filled with LEDs and is covered with plastic. Dismantling the handle of the kettle in case of breakage can take a long time.
Some kettles have a switch that is controlled by a timer.
To connect the kettle to the network, a group of contacts is used, located at the bottom of the stand and turning into an electric plug.
The lid of the kettle is responsible for blocking hot water.

A thermal relay or a temperature heating sensor, which is responsible for heating it to a certain degree, can also cause a breakdown.

Electric kettle device

It seems that studying the device of an electric kettle takes a lot of time, and troubleshooting it at home is impossible, and now the kettle will have to be returned under warranty, but this is actually not the case. The cause of the breakdown can be identified independently. First you need to check if the plug is plugged into the network. If this worked and the water does not boil, you need to unplug the kettle from the electricity and inspect the thermostat in the stand below for scale.

Scale is easily removed by boiling a solution of citric acid in a kettle. If the heating element burned out, it should be replaced.

What should be done if the kettle is leaking? There may be several options: either wait a certain time for 2-3 weeks, until scale forms on it, cover the resulting microcracks with a specialized sealant and glue, or contact a service center and replace the device. It often happens that the button for turning on the kettle does not work, perhaps its luminous element has broken.

Common causes of breakdowns of electric kettles Scarlet, Saturn, Tefal, Vitek:

The breakdown may consist in the oxidation of the contacts that are in the handle;
Oxidation of the contacts that are in the relay;
Damage to the wire in the electrical cord, the contacts must be stripped and reconnected;
Damage to the contacts at the base of the electrical plug itself;
Power button not working.

Progress is running forward and now cordless kettles have become very popular, but they can also be faulty, although they have written off wired electric kettles from many homes.

Cordless kettle Vitek and the reasons for its breakdowns:

Contact damage;
Breakage of the switch;
Breakage of the heat of the heater or coil;
TENA failure;
Burnt contacts in the power button (in this case, it is better to replace the button with a new one);
Thermal fuse failure.

Step by step: do-it-yourself electric kettle repair (video)

A kettle is an indispensable household appliance in the everyday life of every home, because it's nice to wake up in the morning with a fragrant cup of coffee. And how it spoils the mood, if suddenly our household helper, the electric kettle, suddenly stopped heating the water, but thanks to the elementary scheme of the electric kettle, repairs can be done independently and enjoy the taste of an invigorating drink without any problems. Do it yourself, or contact the service - it's up to you.

It is difficult to imagine modern life without electric kettles. High heating speed, attractive appearance and low energy consumption have made it an indispensable appliance in any kitchen, both at home and in the office. This article will introduce you to the device of a modern electric kettle and help you understand all the intricacies of its work.

The idea of creating such a device belongs to the American Colonel Crompton, who first demonstrated his invention at the Chicago World's Fair in 1893. The heating element was built into the base of the kettle, which increased the time and energy consumption required to heat water by an order of magnitude. Due to these shortcomings, the device could not attract the attention of the general public.

Taking Crompton's idea as a basis, the Englishman Arthur Large improved the model by installing a heating element directly into the inner surface of the device, which allowed shorten heating time to the minimum.

The first mass-produced electric kettle was produced in Germany at the beginning of the 20th century by AEG. Some models can still be found in modern design museums around the world.

Types of heating elements

Modern models of electric kettles consist of the following components:

special stand,
a heating element,
frame,
glass flask,
thermostat.

Since the main part of any kettle is a heating element (TEN), according to their design, devices are classified according to the type of heating surface.

How it all works

In order to understand how any device works, you need to familiarize yourself with its diagram. as follows:

Electric current is supplied to the contacts of a special stand XP1. Next, the current passes through the thermostat S1. From this regulator, the current is supplied to the contacts of the heating element. HL - light indicator. S2 is a thermal protection switch that is not involved in the water heating process. It works only if the kettle flask is empty.

This diagram of the kettle is rather conditional and may differ depending on the model and the number of additional functions of the device.

In a more generalized form, the principle of operation of an electric kettle is the sequential implementation of the following actions:

Installing the device on a special stand, the user connects the kettle to the mains and by pressing the button activates the operation of the device. By means of an electric current, a heating element boils water. The maximum allowable heating temperature for such devices is 100 degrees Celsius. Due to various impurities present in tap water, this value may drop to 93-95 degrees.
Thermostat determines the temperature of water heating and, after reaching a certain mark, automatically turns off the electricity supply to the heating element.
If your device has keep warm mode, the kettle will continuously heat the water after it has cooled to a certain temperature.

Many modern models are arranged on the principle of a thermos: the inner flask is isolated from the outer case by an “air cushion”, which contributes to a longer preservation of high temperature.

When choosing an electric kettle, you should pay attention to the material from which it is made. Devices with a metal base take the longest to heat up and use a large amount of energy. Ceramic kettles retain heat for a long time and have a faster heating rate.

Automatic Shutdown Mechanism

This mechanism is based on bimetal plate, which reacts to the amount of hot steam coming from the flask of the apparatus. In different models of devices, this mechanism is located in different places, which does not have any effect on efficiency or durability.

When boiling, water begins to release a large amount of hot steam, which passes through the tube to a special plate. The hot steam heats the tongue of the plate and, under the influence of temperature, it presses the switch button.

As a rule, the cavity of the handle-holder is used as a tube for transferring steam. This option is the most preferable, since the possibility of leakage is excluded.

Precautionary measures

Before you start using the kettle, you should carefully read the instruction manual. If for some reason it is missing, you must adhere to the following rules.

Never turn on the appliance if the amount of water in it does not exceed the minimum allowable value. Otherwise, it will lead to the burning of the electrical circuit.
For trouble-free operation of the device, it is recommended to use a separate socket.
Never cover the body of the kettle with other objects.
If the power cord is broken or damaged, stop using the device.
Regularly clean the interior surface after unplugging the appliance from the mains.

Dear visitors!!!

To understand the principle of operation of an electric kettle, in comparison, an explanation is given on the electrical circuit of the iron, since the circuits of two electrical appliances have a slight difference in the principle of operation of the contacts of the bimetallic plate of the electric kettle's thermostat and the iron's thermostat, and you will see this for yourself by reading this topic.

Electrical diagram of an electric kettle

The principle of operation of electric kettles in comparison with the principle of operation of an electric iron is almost the same. The closing and opening of contacts for two types of household appliances is based on the effect of the heating temperature transmitted to the contacts of the bimetallic plate. A similar iron scheme

if introduced into the design of an electric kettle, the kettle will work in the on and off mode with heated water at certain intervals.

Scheme and description

The connection diagram of the electric kettle elements is as follows:

One wire from an external source (electrical outlet) is connected to one terminal of the heater. The second wire is connected to the terminal, the circuit of which is connected in series through the thermostat of the electric kettle, then the current flows to the other terminal of the heater. The difference between the iron thermostat device and the electric kettle thermostat is that as the bimetallic plate of the iron thermostat cools down, the contacts close and the iron heater heats up again. In an electric kettle, as the bimetallic plate heats up, the thermostat contacts open and the electric kettle is turned on again using a switch. An LED bulb with resistance is connected in parallel to two terminal connections of the heating element of the electric kettle.

Do-it-yourself electric kettle repair

The device of disk electric kettles is based on the same principle of operation.

This topic is related to the following questions:

How to repair a Vitek electric kettle;
How to repair an electric kettle Scarlet;
How to repair a Tefal electric kettle;
How to fix a Polaris electric kettle;
How to repair a disk electric kettle.

Such elements of an electric kettle as:

thermostat;

- in case of its malfunction, it can be replaced with a new element. thermostats and heaters are available in specialized stores. An easy way to troubleshoot an electric kettle is to connect two wires to the heater's contacts (if you can't purchase a new thermostat). With this method of troubleshooting, it will be necessary to monitor its disconnection from the outlet so that the electric kettle does not overheat. Testing of all elements of the electric kettle is carried out in a passive way (without connecting to an external source).

If the cause of the malfunction raises the question: "How to repair the electric kettle button", - such a reason may be:

oxidation of the contacts of the electric kettle button;
burning of the contacts of the electric kettle button,

- with this malfunction, you can clean the button contacts or replace the button (electric kettle switch) with a new one.

Scarlet electric kettle repair

The photo shows an electric kettle Scarlet. What possible causes of failure are typical for such models of electric kettles?

- Possible causes of the malfunction are found in our practice as follows:

oxidation of the contacts of the thermal switch (installed on the handle of the electric kettle);
oxidation of the contacts installed on the outer part of the bottom of the electric kettle (thermal relay);
wire break in the network cable (electrical cord);
break in the wire of the mains cable at the base of the plug

and other reasons.

In this example, the cause of the malfunction was a malfunction in the thermal relay installed at the base of the electric kettle.

electric kettle thermal relay

After establishing the cause of the malfunction, the electric circuit of the kettle was slightly changed.

The thermal relay is made in a stamping design and cannot be repaired. How to find a way to fix such a problem?

thermal relay diagnostics

electric kettle thermal relay

The thermal relay directly has a contact connection with the connector in its single stamping design. To do this, the thermal relay contact was removed and two wires were directly soldered to the connector pins.

The result was the same electrical circuit, with the exception of the thermal relay contacts from this circuit. That is, two wires were soldered to the contacts of the heater.

diagnostics of the heating element \heating element\

To check individual electrical elements, in particular checking the heating element, the Multimeter device is set to the range for measuring resistance.

With two probes of the device, we touch the two contacts of the heating element, if the heating element is in good condition, as shown in the photograph, the display of the device will indicate the presence of resistance, that is, the electrical circuit in a good example closes on the spiral of the heating element.

Diagnostics for the thermal switch can be performed both with a probe and with a Multimeter.

thermal switch

Two probes of the device are connected to the contacts of the thermal switch, the device is set to the range of least resistance and, accordingly, in the same way

we carry out diagnostics.

the device indicates a break - when disconnected

thermal switch

the device indicates the presence of a short circuit - when the thermal switch is on

In this example, you can clearly see that the thermal switch of the electric kettle is working.

connection of instrument probes with thermal switch contacts

The diagnosis of a light bulb consisting of two electrodes in a glass bulb cannot be checked for resistance. To do this, the device must be set in the capacitance measurement range, measured in picofarads, since this light bulb has a capacitance.

That is, like the plates of a capacitor, the two electrodes of a light bulb will also have their own specific capacitance with this method of measurement.

With such a diagnosis of a light bulb with two electrodes, appropriate probes are made in an independent way for connection to a socket for measuring capacitance.

Hello, I have a disc kettle brand irit. How to replace a disk heating element?

Good afternoon!!! And tell me if the electric kettle turns on and the light is on that the kettle is turned on but it doesn’t heat the water, what can it be, it’s necessary that the heater burned out ???

Tell me please, the kettle heats up slowly, about 20-30 minutes, what should I do?

Hello. Victor, please tell me, a sharp smell of burning plastic suddenly appeared from the power button (the button is at the top of the handle) Is it possible to do it yourself? As I understand it, the wiring began to burn, and is it still possible to get rid of this smell later? It also appeared in the kettle itself .

The Vitek electric kettle began to leak after a summer of non-use. How to fix such a problem?

Victor, thanks for the answer, a kettle with a disk heating element.

Used 3 kettles in the last 5 years. After a year and a half, everyone had one malfunction: it starts to heat the water and after some time it turns off (quietly clicks), but it does not turn off completely - the power indicator light is on. After 20-30 seconds, a quiet click again - the kettle starts working again. And so 3-4 times until it boils completely, after which it turns off completely. What is the reason? Kettles are different - and disk TEFAL and PHILIPS with a spiral. Thank you.

Hello. My problem is the following ... The kettle as a whole works when the water boils - it turns off, BUT during this time, the button goes out periodically from time to time for a while, then turns on again and so on until it boils. What is this?

the glass container of the electric kettle was broken. Is it possible to order it somewhere and or throw out what is left?

Good afternoon, please tell me, there is a Polaris PWK 1783CAD kettle, with the ability to set the heating temperature. A problem arose, it began to leak in the area of the viewing windows, they are stamped at the factory, apparently due to the difference in the thermal expansion of the materials, a micro-hole appeared. It leaks when the water cools, while the hot keeps normally. It seems that you can try to smear with sealant whether there are food products that can be used in the kettle. Or maybe there is some other way to fix this type of malfunction. Thank you in advance.
