How to fix the kettle at home.

The electric kettle was invented in 1900 by the American engineer Whitcomb, when electricity was still far from being everywhere. Contemporaries did not take the invention seriously, considering it an eccentricity. However, for more than 100 years, the electric kettle has turned from eccentricity into an indispensable attribute of any kitchen. Even if the house has gas, electric kettle is still used. He boils the water much faster, there is no need to be on duty near him, waiting for the moment when he should be turned off. From the point of view of saving energy, it also looks much more progressive than its "copper" ancestor. No one kilocalorie, created by a heating device, is wasted, which can not be said for a gas burner that simultaneously with boiling water, 40% warms the surrounding air. But sometimes there is a need to fix it and this miracle of technology.

The device and the principle of the electric kettle

The schematic diagram of the electric kettle is quite simple. It is a sealed container, inside which is mounted a heating device - heating element (thermal electric heater). Inside the heating element is a tungsten coil, which heats up when it is connected to the mains.

For convenience, the kettle is equipped with:

  • manual switch button located on the body
  • power supply circuit breaker

Using the manual button, the kettle starts up, with the automatic switch it stops working (although it is possible to do this manually as well).

The power button is a normal toggle switch that switches a contact pair from one mode to another.

The operation of the circuit breaker is to de-energize the device when the water reaches the boiling point. This is achieved by installing a thermocouple in the path of the water vapor that drives the rod that controls the supply of power from the network. The thermostat is a bimetallic plate, which when heated in a certain way changes its geometric shape.

Most modern electric kettles are equipped with additional “amenities” - the illumination of the power button (additional signaling of the apparatus operation), the illumination of the water inside the flask (the scale is well visible, it allows for timely removal). On some set timers, through which you can adjust the degree of heating of water, not bringing it to a boil. And also set the time the kettle is turned on.

The body of the electric kettle is made of various materials: glass, plastic, metal. There are exotic models in which the flask is made of rock crystal, and the heating disk is silver.

Glass used thin-walled, high strength and heat resistance. However, to test it for strength and drop it on the floor once again is not recommended.

Plastic cases are made from food plastic, the vast majority of inexpensive kettles are plastic. However, this material has a number of flaws that negatively affect its reputation.For example, the ability to emit unpleasant odors during warm-up or melt, if the thermostat has suddenly failed.

The most practical are electric kettles that are made of metal. As shown by practice, it is the metal shells that best withstand the test of time.

There are also combined models where plastic, glass and metal are combined.

In order to seal the cracked plastic body of the kettle, you need to dissolve the chips of food grade plastic with dichloroethane to the state of "liquid sour cream." Clean up the crack, degrease, dry. The resulting solution carefully "putty" the damaged place. To sustain a drying till 24 o'clock. It is impossible to use other glues, including epoxy, since when the kettle is heated, they will emit co-homogenous substances into the water. Dichloroethane completely evaporates after 24 hours.

Depending on the design features, electric kettle breaks can be divided into two unequal segments.

In the first, most numerous, there will be problems in the electrical part of this popular household appliance.

In the second, relatively small, mechanical damage will remain, occurring mostly due to carelessness or in the process of misuse.

The kettle mechanics are simple, actually consists of a cover that is fixed on the upper part of the body and a locking mechanism that keeps the lid closed.

Sometimes the cap is naughty and does not want to properly close or open. Then you need to treat it with attention - inspect, identify the cause of this behavior and eliminate.

As a rule, the involvement of specialists in this situation is not required. Solve the problem succeeds on their own.

The situation is completely different with the electric part of the kettle. After all, it is she who performs all the main work, and the main load lies on the heating element and the thermostat.

The heating device is of two types - disk and spiral. The first is mounted in the bottom of the flask with water, the second is fixed to one of the walls of the case. Judging by the proposal of electric kettles on the shelves of stores, disk heaters gradually displaces the spiral. This is due to the higher efficiency of the disk heating elements, as well as the advantages in operation.

For example, it is very difficult to wash and descale the inside of a kettle equipped with a spiral heater.

The thermostat, in principle, is an eternal detail, cannot break anything in it, since it is a plate pressed from two different metals. However, sometimes it fails. More precisely, the mechanical drive breaks down, by means of which it controls the button for switching off the kettle.

With what breakdowns can the kettle be returned to the seller

If the purchased product does not match the declared quality or during operation there are problems in its mechanisms, according to the Consumer Protection Act, the product can be returned to the seller and get the money back. For this, certain conditions must be met.

  • - the kettle was not in use, appearance, factory seals and labels, as well as the presentation remained intact
  • - the availability of a cash receipt or other document certifying the purchase (in the absence of such documents, it is possible to refer to the testimony of witnesses)
  • - on the day of circulation there is no similar product for replacement
  • - the claim for the return of money must be satisfied no later than 10 days from the date of presentation
  • - It is necessary to have a civil passport with you to compile the act of returning the kettle.

In case the purchased teapot is under warranty, it can be repaired only in the warranty workshops listed in the warranty card. Self-disassembly of the device and an attempt to eliminate the malfunction entails the termination of the manufacturer's warranty obligations.

From this follows a simple conclusion. It’s wiser to use a warranty than to try to fix the kettle yourself. There is no reason to hope that “they will not notice” traces of the autopsy in the workshop. A professional who is engaged in the repair of household appliances daily and for many years, just one glance is enough to determine whether a kettle understands or not. In addition, there are various tricks on the part of the manufacturer, which are aimed at avoiding such situations. They are not visible to the eye, but are sufficiently clear to determine (and prove) the fact of unauthorized disassembly with their help.

All defective goods are subject to return or exchange, at the request of the buyer. An exception may be only complex technical products that are subject to examination for factory or warehouse defects. The kettle, of course, does not fall into this category.

In the event of controversial issues, the seller is obliged to conduct an expert examination of the goods at his own expense. The buyer has the right to be present during the examination. If, as a result of the survey, it is proved that the marriage of the teapot (or other goods) has been formed through the fault of the buyer, then it will be obliged to reimburse all expenses for examination.

Electrical fault finding

In order to diagnose the electrical circuit of the kettle, you must use a multimeter (or tester).

Inspection, as a rule, begins from the place where the power cable is plugged into the outlet and ends at the thermostat. To consistently make measurements on all parts of the circuit, it is necessary to disassemble the body of the kettle.

But first you need to make sure that the power cord and the outlet to which it is connected to are working. And also check the presence of voltage on the stand under the kettle, through which the current is transferred to the heating element.

If there is no open circuit, unscrew the three screws at the bottom of the kettle and remove the protective cover. Often, apart from screws, the cover is additionally fastened with plastic latches, as on a mobile phone. Therefore, it is desirable to have a thin and flat screwdriver in order to disengage the plastic locks.Sometimes screws are closed on top with decorative caps, which need to be accurately picked out with a thin screwdriver.

If the screws do not get out of the plastic case, the most effective way to solve this problem is to touch them with a heated soldering iron. The plastic will soften slightly and release the clamped screw.

After the cover is removed, a visual inspection of the disk heater, as well as contacts that supply it with electric current, is performed. The contact surface must not be melted or covered with metal scale. A properly working contact looks monotonous, without purple spots, which indicate its overheating.

If there are no obvious signs of circuit damage, the contact group and the heating device are tested with a multimeter. The resistance of a serviceable heater is approximately 30-40 Ohms. The readings taken from the damaged heater (there is no resistance, the tester shows the symbol of "infinity") will speak about the breaking of the circuit. In this case, it must be replaced.

Check heater operation

Also it is worth checking the work of the resistance associated with the LEDs. Their operating range is 13-15 ohms.If the ohmmeter gives other indicators, the resistor should be replaced.

For further testing of the power supply circuit of the kettle, you need to dismantle the handle in which the temperature sensor (or temperature sensors), the manual power button and the automatic shutdown unit are located.

The cover of the handle is attached either with screws or plastic locks-latches. Inside the handle constantly circulate evaporation from boiling water, and this creates favorable conditions for metal corrosion.

After thorough inspection, all elements are additionally tested with a multimeter. Terminals are cleaned with sandpaper or a file. A broken wire is restored.

Damaged parts, as a rule, simply change. A large assortment of spare parts for electric kettles are available for sale; their prices are quite affordable. The main thing is to strictly observe their compliance with the model of the apparatus under repair.

How to fix the kettle with their own hands: step by step instructions

Consider solutions to the following problems most commonly encountered in practice.

If leaking

Two reasons are possible. One - there was a mechanical damage to the case.The second - the rubber gasket located between the case and a heating element has worked. In the first case, the kettle flask is repaired, if possible. In the second, the gasket changes.

Sometimes, to eliminate the leak, it is enough to tighten the screws of the spiral heater to seal the rubber gasket. But if not - then the spiral is disconnected, the old gasket is removed and a new one is installed.

Replacing the gasket in the kettle

For replacement it is necessary to disconnect the heating element.

Pay attention to the condition of the old gasket. If the reason for its failure is a thick layer of scale, then from now on it is often necessary to clean the inner space of the container from the formation of water stone. Otherwise, the new gum is waiting for the same fate.

The most famous way to clean a kettle from scale is citric acid. A half liter of water is filled with a bag of citric acid and boiled with the lid open. If necessary, the procedure can be repeated several times, alternating with pauses to cool the kettle (about half an hour).

But there are other ways. Vinegar can be used instead of citric acid (200 gr. Per 100 gr.water), as well as Coca-Cola and even potato peels.

Synthetic detergents should not get carried away. If even milligrams of these substances remain on the walls of the kettle, then once inside the body, they will harm health and health in general.

In teapots with disc heaters, the flow is eliminated in the same way.

If the model of the kettle is collapsible (which is not always the case), as a means of preventing leakage, you can apply cleaning of the silicone gasket from the water stone. Removing the case from the heater, you can remove the gasket and rinse it with plain clean water, clean it from fine sand with a soft brush, which, in fact, breaks the tightness. It is also carefully recommended to clean the heater itself, as well as the inner surface of the kettle body. After that, the gasket is installed in its place and the device is going to its original state.

A clean and flexible gasket can last for a long time, if you monitor its condition in a timely manner and prevent fossils on the surface.

Failure of the thermostat. Disassemble the body handle and replace the regulator. It does not make sense to repair such parts, because it will take a lot of time, and how much as a result it will serve is not known.

Replacing the thermostat of an electric kettle

Not repaired at home

When disassembling you need to inspect the drive rod of the thermostat, which sometimes breaks. And a spring supporting a bimetallic thermocouple. If the matter is in them, then you can temporarily replace them from the material at hand.

Disconnects ahead of time

A similar situation is a violation of the thermostat. The lid of the kettle handle is removed, the spoiled thermostat is removed. In its place a new one is installed, the contacts of the circuit are connected. Before final assembly, it is tested again with a multimeter.

One of the reasons for the violation of the correct operation of the thermostat may be the premature drying of the thermal paste at the place of contact of the thermal sensor with the heater. This can be determined visually and tactilely. If the thermal paste has become dry, fragile, has lost its elasticity, then it is time to change it. This usually occurs no earlier than after 2 years of operation.Replacing the thermal paste is not a difficult procedure (remove the old one with a napkin and apply a new one). It serves to improve the thermal conductivity and eliminate the air space between the heating disk of the kettle and the thermal sensor. You can buy it in stores selling accessories for computers.

Consistently, as described above, to diagnose the electrical circuit of the entire apparatus. If a power break is found, replace the damaged part, clean the terminals with sandpaper.

Does not heat water, although the light is on

The most likely is the failure of the electric heating device. Or the oxidation of the contacts responsible for its nutrition. To solve the problem, it is necessary to remove the bottom cover of the kettle, carry out diagnostics and eliminate the cause of the malfunction by results.

Electric kettle button is not fixed

A fairly common phenomenon. Usually due to the fact that in the process of long-term operation, it bursts or falls out of the landing slot, a steel spring fixing the position of the switch.In order to fix the button, you must first remove the handle cover and access the button mechanism. Then the button body assembly is disconnected. If the spring turns out to be whole and it just needs to be inserted into the socket, then replacement may not be necessary. Perhaps to restore performance it will be enough to slightly stretch it in order to return the former elasticity.

The teapot coil cracks when heated

A clear sign that the level of scale on the spiral is approaching a critical state. If you let the formation of water stone on its own, it is likely that the spiral will quickly fail and have to be changed.

As soon as the first signs of cod appear, even the smallest ones, it is necessary to urgently take measures to remove scale on the walls of the kettle and, especially, on the heating element.

Replacing disc and spiral heater

If the diagnosis of the kettle has shown that the heating element has failed, it must be replaced, since it cannot be repaired.

The spiral heater is held in the case usually with 3 screws that need to be unscrewed.Next, the spiral is released from the terminals connected to it, and carefully removed from the body. Together with the heater, it is desirable to change the rubber gasket, which prevents the flow of water from the flask to the outside. Reassemble in the reverse order.

It's not so simple with teapots equipped with disc heaters. Disassembly and replacement of the heating element in such devices is not provided by the manufacturer. The heater disk itself is soldered to the body and is an indivisible whole with it. In addition, even if you remove it from the kettle, it is almost impossible to buy a replacement. They are not on sale.

Such teapots require more careful care of themselves. Because in the event of a heater breakdown, he has one road - to a landfill or at best for parts. Especially carefully you need to monitor the formation of scale and clean it in a timely manner.

To do this, follow the simple rules.
