In detail: DIY ariston electric hob repair from a real master for the site my.housecope.com.
The high manufacturability of hobs raises doubts about the possibility of repairing them with their own hands from users and home craftsmen. But, like all sophisticated electronic equipment, kitchen surfaces are composed of separate functional units that interact with each other.
Having understood the functionality and interaction of components, having studied the methods for determining common malfunctions, understanding what and thanks to what turns on, you can, without resorting to the services of masters, carry out a simple repair of the hob with your own hands.
All modern hobs work according to the same principle - the user acts on the control sensors, thereby turning on the power relays that switch large currents in the heating elements.
Therefore, first you need to localize the breakdown, that is, identify the defective node. It is assumed that the cable, connection terminals, fuse, voltage presence is checked, and command set errors are excluded.
Cooking surfaces (panels) are electric heating kitchen appliances (electric stoves) that have glass-ceramic outer cover. Glass-ceramic has great strength, allowing it to withstand a significant weight of the cookware, and has good thermal conductivity.
The attractive appearance, which some manufacturers (for example, Hansa) complement with artistic decorations, allows the stylish hob to successfully fit into the modern kitchen design.
Artistic hob design
Heating elements hidden under the glass-ceramic surface are of several types:
Spiral, working like conventional heating elements;
Corrugated tapes (modified filaments);
Halogen infrared lamps (HaloLight technology);
Induction coils that only heat the cookware material.

Various designs of thermoelectric burners
Burners of the first three types convert electric current into heat according to the Joule-Lenz law in the same way as an incandescent filament in a conventional light bulb or a spiral in a conventional electric heating element is heated. The principle of heating using induction is described in detail in the article on induction boilers. Do-it-yourself repair of induction hobs will be discussed below.
Thermoelectric heaters have a heat-releasing corrugation or spiral laid in a heat-resistant material, connection terminals, as well as heating sensors presented in the form of a bimetallic plate located on the line of the radius or diameter of the burner. Expanding, the bimetallic plate acts on the contacts, closing or opening them.
Hob burner device
Depending on the design of the hob, the temperature sensor contacts can be power contacts (acting like a thermostat), or signal contacts included in the electronic control circuit. Malfunctioning sensors (thermostats) are a common reason that the hob does not turn on.
In general, repairing hobs differs little from repairing electric stoves, which is described in detail in one of the articles of this resource. The main visual difference is the presence of a glass-ceramic surface and the type of heaters, the spirals of which are visible through the transparent surface. Also a characteristic distinguishing feature is sensory electronic unit and the complete absence of the usual control levers.
Hob touch control unit
Therefore, the greatest difficulty in the repair of electric hobs is the electronic touch control unit, which is also a display. To repair it with your own hands, you will need knowledge in radio engineering and special equipment.
But otherwise, the hob is not much different from an electric stove - the heating elements are switched on by power relays, controlled by an electronic control board, which receives signals from the sensor.
But at first, even without disassembling the hob body, you can determine the malfunction of the touch display and the electronic control unit. As a rule, the receipt of a command from the user is accompanied by a sound signal and is displayed on the display. If there is no reaction to touch, then it becomes clear that there is a breakdown in the sensor.
Indication of a properly working hob
The sensitivity of the sensor may deteriorate due to severe surface contamination. It should be remembered that the entire glass-ceramic surface of the hob requires careful maintenance and cleaning, otherwise cracks may form from the accumulation of limescale and burning.
Operating a stove with cracked glass ceramics will lead to its further destruction and breakdown, therefore, timely care and cleaning of the hobs is needed, as shown in the video:
VIDEO
VIDEO If cleaning the surface above the sensor does not bring any results, you should disconnect the hob from the mains, first disconnect the line from the power supply, disassemble the case and remove the electronic board with sensors.
Electronic board with display elements and control sensors
As you can see from the figure, the electronic board of the control unit has many small parts, including microcircuits, so repairing such a module with your own hands requires deep knowledge of radio engineering. If the malfunction of the sensor control unit is reliably established, then it is better to take this board to a specialized repair shop.
If surface diagnostics have not yielded results (the command turns on, but no heating occurs), you should look for a malfunction in the switching power unit. Some models of hobs can independently diagnose some malfunctions, signaling them using the error codes that appear on the display. You should carefully study the user manual and these codes - this will save time when troubleshooting.
Error codes for some hobs
The power control unit (switching) of the hob consists of relay groups controlled by an electronic sensor unit. When the operating mode is selected, one or more relays are energized, supplying power to the respective heating elements.
Arrows indicate power relays
Even for a novice master, it will be easy to disassemble the panel case with his own hands in order to independently determine the malfunction of a heating element or power relay. For this purpose, you will need a multimeter and skills to work with it. You will also need to determine the type of heating element itself in order to check it correctly (for example, the resistance of the induction coil is close to zero).
More experienced craftsmen often use a different method - they check the voltage supply to the main nodes, moving from the power terminals through the power relays to the heating elements. The power relay contacts may burn due to frequent switching on, and checking the presence of voltage at the input terminals of the burner will determine if the relay has been activated.
Measuring the supply voltage of a cooking zone
It should be remembered that many elements inside the enclosure carry life-threatening voltages. Working under stress requires focus, mindfulness and sober thinking.
If the terminals of the hotplate are normal supply voltage, you can check the performance of the heating element visually - the filament should be warmed up. But, if the burner turns on, but does not heat up to the required temperature, you need to measure the flowing current. The easiest way to do this without breaking the circuit is with a multimeter equipped with a clamp meter.
The use of a clamp meter to check the current in the power circuits of the hob
Knowing the maximum power of the burner and the supply voltage, you can calculate the rated current according to Ohm's law. In the case of heating elements that work like a heating element, a decrease in the current and heating temperature may be associated with malfunctions in the electronic control unit, thermostatic elements or in the power relays.
If the halogen burner does not heat well, then an internal chemical change in the composition of the gas in the heating element or degeneration of the spiral is possible. In this case, if all other possible malfunctions have been ruled out, the HaloLight Heater should be removed and replaced.
The appearance of the hob burners without glass-ceramic coating
It happens that the burner turns on, but after working for some time, it turns off ahead of time. Improper operation of the heating element may be due to a malfunction temperature sensor installed on the hotplate. In order not to change the entire expensive burner, you need to disassemble the sensor with your own hands, clean or bend its contacts, as shown in the video:
VIDEO To diagnose and repair the hobs, you will have to dismantle the equipment from the countertop, disconnect the power terminals and disassemble the case. It must be remembered that the glass-ceramic coating is vulnerable to point impacts and loads. Therefore, when turning the hob over, avoid small objects falling under the surface so that the weight of the cabinet is not applied to one point.
Mandatory care in the workplace when repairing a hob
It goes without saying that bumps, scratches and carelessness should be avoided. You should carefully examine the hardware fastening mechanisms - these can be bolted connections, screws, or latches. Some elements, for example, an electronic board, can be additionally fixed with glue or adhesive tape. When disassembling a particular model of the hob, you should first study the articles, images, videos available on the Internet.
Experienced craftsmen always check the physical strength of the terminal connections (with the voltage removed) - very often it is poor contact that is the reason that some burner does not turn on. If a faulty burner is detected with a multimeter, or a breakdown in the electronic board is detected, then it can be turned off with one hand alone, without the aid of a soldering iron, and taken to a workshop, where, to replace radioelements or relays, you will need skills in working with a soldering iron and the ability to work with radio components.
VIDEO
VIDEO The peculiarities of the operation of induction heaters can very often be interpreted as a breakdown - the command is given, but the burner does not turn on, there is no characteristic glow, and heating does not occur.The fact is that the metal of the cookware and the coil of the burner form a single oscillatory circuit, due to which high-frequency oscillations arise that induce currents in the metal kitchen utensils.
VIDEO As mentioned above, the physical processes and the principle of heating using induction are described in detail in the previous article on induction boilers - you should familiarize yourself with this material in order to have an understanding of the operation of such equipment. In the case of hobs, induction heating is used to heat cookware, but the principle remains the same.
The working surface of the induction heater does not burn immediately after switching off
Repairing induction hobs requires an understanding of the high frequency generator and the self-oscillating processes that occur in the electronic circuit. The most susceptible to breakdowns are power switches (transistors), diodes and high-voltage capacitors that are part of the circuit. Transistors like these are often MOSFETs, and are not called bipolar semiconductors, but they can be detected if they are out of order.
VIDEO As shown in the video, technicians in service centers can determine faults in electronic circuits, relying on experience, having available equipment and a large stock of various element base in order to carry out repairs by replacing defective elements. Surface diagnostics of the main components is carried out by the breakdown test method.

Electric, induction and gas hobs are used for cooking. Each of them has its own advantages and disadvantages, and there are also a number of malfunctions that can be eliminated independently if they occur. Do-it-yourself hob repair can be done subject to certain recommendations and if you have the necessary tools.
Hob repair Bosch, in some cases, you can do it yourself.
If, with the power supply connected, one of the burners does not work or the entire device does not work, we carry out the following work:
We check with a multimeter the voltage in the outlet. If it is, then the problem lies with the hob itself. You can check using the indicator, but it only indicates the presence of voltage. A significant change in the current indicators can lead to the operation of protective mechanisms.
We check the condition of the electrical cord and plug. If there is mechanical damage, it will be enough to replace the cord or plug. You can also check the supplied current on the panel itself, since mechanical damage is not always the cause of a malfunction of the cord and plug.
If the cord with a plug, the socket is in good condition, we dismantle the hob.
If you repair a glass-ceramic hob with your own hands, you should know that the malfunction of some structural elements can only be detected with a multimeter, by taking measurements in individual sections of the circuit. When considering a Bosh hob, you should pay attention to the following elements:
In the absence of resistance or at low rates, these elements should be replaced.
Another common problem is a broken wire in the hob connection block. Under certain circumstances, they can burn out or, due to poor installation, there may be poor contact. Checking for such a malfunction can be quite simple.
Let's highlight a few more problems that lead to improper operation of the hob:
Some models have fuses that can blow out due to high voltage surges. Their cost is low, the replacement procedure is quite simple. In order to protect expensive equipment from such situations, you should install a surge protection device. If the fuses constantly fail, you should check the operating features of the equipment itself, since the problem may not be in the indicators of the supplied voltage.
The burner may not work due to the fact that the contact on the heating element has disappeared. If the wiring is unsoldered, you can resume work, for which you need to have a soldering iron and be able to use it. The problem may be associated with the power supply, which also often loses contact.
The design of electric hobs is quite complex, but many of its elements are highly reliable.
The principle of operation of an induction hob is to directly heat the contents of the cookware, and not the surface of the stove or the cookware itself. Due to the fact that the hob remains constantly cold, such kitchen appliances are very popular.
There are several problems in which you can repair an induction hob yourself:
If the hob does not turn on or does not turn off immediately, do not panic. Modern models from the manufacturer in question are able to determine the type of cookware, its absence on the hob. Therefore, if the cookware is not suitable for induction heating or if it is not installed, then a protective mechanism is activated. Do not forget that induction cookers do not heat the hob itself.
If the heat is weak, then initially you should check the type of dishes used, whether it fits the recommendations.
Repairing induction hobs, as in the previous case, you need to start by checking the circuit for the presence or absence of contact. Fuses often fail, as there are often power surges in the network. In this case, simply change the fuse.
The rest of the repair of induction hobs is similar to the repair of electrical panels.
To repair the electric and induction hob, you need to have the following tools:
Screwdriver Set. In order to carry out many dismantling work, you need to have several different screwdrivers, which may differ in size and type of tip. In addition to ordinary screwdrivers, you should pay attention to the need for an indicator that detects the presence of voltage.
The mounting knife is often used when carrying out electrical work. As a rule, it is necessary for changing the length, stripping wire strands and other similar work.
Pliers are often used during assembly work. However, they often have a sharp part that can be used to cut the veins.
It is often necessary to have wire cutters.
In addition, a multimeter may be needed to determine the voltage value. It determines various parameters of the supplied current. A soldering iron may be needed when carrying out repair work.

This article will focus on repairing touch-sensitive hobs. Unfortunately, in most cases, it is not always possible to repair them with your own hands. However, first things first.
In case you have mechanical control, which is usually the case for dependent panels or for stationary electric stoves, then you can read about faults here. Everything else I will divide into two parts: what happens and what cannot be repaired with my own hands.
If the touch control works, you can change the power, turn on and off the hotplate, but at the same time the hotplate either constantly works, and it starts working immediately as soon as you turn on the hob, or it does not work, regardless of the mode that you set through the sensor, then malfunctions of two types can be distinguished:
If the hotplate heats up immediately when the hob is turned on and does not respond to changes in modes, then it is most likely that you have a sticking of the relay contacts, which is responsible for this hotplate. Here you need to check the relay contacts. Relays usually have two pairs of contacts. One pair comes with food. When power is applied, the coil draws in the core, which closes the contacts. The second pair is just the contacts that the relay controls. The most likely reason is the welding of the contacts. In principle, if you know how to hold a soldering iron in your hands, then you can try to replace the relay with your own hands. You need to check two things: whether the power supply to the relay coil is turned off and whether the relay contacts open. If the coil power appears immediately when the panel is turned on, then you will have to go to a repair shop. If the coil power appears when you turn on the hotplate with the touch panel, then you need to check the control contacts. But in this case, as a rule, they are always closed. If the problem is in the relay, then in any case, a replacement will be required.
If the relay is working properly, but the burner does not work, while the power is supplied to the relay, and the power contacts are closed, then we read here how to determine the malfunction of the burner.
If this is a new panel that you installed yourself, or, suddenly, half of the panel stops working, or the sensor works, but the burners do not turn on, then look at the terminal block. In touch panels, the terminals in the block can be distributed in this way: one terminal is responsible for powering the electronics, the other two power the burners. That is, the situation when the electronics is working, the touch panel shows that the power of the burners is regulated, but the burners themselves do not work at the same time.
There may be two repairable problems and one conditionally repairable problem.
The sensor is triggered with some delay. Some manufacturers have deliberately made this delay to prevent accidental pressing. That is, in order for the sensor to trigger, you need to put your finger in the required area and wait a little (usually up to two seconds), after which the sensors will react quickly for some time (sometimes any sensor triggering occurs with a delay - the triggering algorithm is determined by the manufacturer).
Child lock might be worth it. Read the instructions for your panel about the lock or child protection mode.
It is possible that the glass above the touch panel or on the back side is somehow dirty. If wiping the glass does not help, then you will have to contact the service center.
Some hobs have a heating function. Usually, in this case, the display does not show 0, but the crockery icon | _ | (like half zero). In this case, the hotplate does not turn off completely, but goes into heating mode. Water, for example, will not boil in this mode, but will remain very hot until you turn off the hotplate or an automatic shutdown occurs, if provided by the manufacturer.
This is most likely not a malfunction. The cooking temperature in touch-sensitive hobs is adjusted by turning it on and off. The more the power is set, the less frequent shutdowns occur and the longer the turn-on period. At maximum setting, the hotplate works without switching off, except in case of overheating of the hotplate. In this case, the temperature sensor will be triggered. As soon as the hotplate cools down, the temperature sensor is triggered and the hotplate turns on again.
The malfunction can be conditionally removable and not. I wrote about this malfunction here. In this case, replacing the temperature sensor will help.
There may be a malfunction of another kind. The problem may lie in the electronics, then you will have to go to the workshop.
This is where the conditionally repaired malfunctions end, so we turn to the malfunctions that you are unlikely to cope with on your own. Therefore, to eliminate them, you will have to contact a specialized workshop. I do not particularly recommend contacting service centers. High-class specialists rarely sit in them, and often you overpay for some services. Therefore, it is better to contact private companies. Repair can be much cheaper, but you need to carefully approach the choice of the company.
This usually happens with panels that are many years old. This is largely due to electrolytic capacitors, which lose their capacity over time. In theory, you can try to replace them. In practice, such a replacement helps only 50%. In this case, especially if the panels are more than 10 years old, it makes sense to think about buying a new one.
This includes all other faults that have not been considered.
Summarize. The malfunctions of analog elements, that is, non-electronic ones, can be considered conditionally removable. In this case, if you have the necessary skills, you can try to fix the problem yourself. When it comes to electronics, it is unlikely that someone will advise you on the Internet, because when it comes to electronics, it is not always possible to immediately determine the cause, even when the master directly examines the panel. And it's even more difficult to explain what a diode, transistor and other electronic components look like.
Last week, the Hotpoint-Ariston c3vm57ru / ha electric stove, which has served faithfully for 5 years, gave its first serious failure. We set up to cook young potatoes and, returning to the kitchen after 10 minutes, were surprised that the water in the pan did not even boil during this time. Further inspection showed that the most frequently used burner on which she stood had stopped heating up.
The prices for diagnostics (from 800 rubles) and repairs (from 1300 rubles) on the website of the official service center were not at all pleased, so I decided to try to fix it myself. It is not for nothing that an engineer diploma and an instructor's diploma is gathering dust in the closet)). Poindexil options for malfunctions with similar symptoms and found out that most often in such cases the switch and the coil of the burner fly, and the wires burn out and the contact in the contact group disappears. Through simple manipulations with the switch (turning on and waiting for clicks of opening and closing contacts), I found out that it was not him. Then it was decided to perform an autopsy on the patient. I did not find instructions for disassembling this model anywhere, so I decided to write down the post - maybe someone will need it.
So, disassembly requires a Phillips head and Torx t20 screwdriver. The hob of the hob at the back is screwed with torx screws:
More from the outside of the mounts were not visible at first glance, but something was holding the top cover in front. I even had to completely remove the back cover to understand what was holding it. It turned out that they were holding screws screwed in at the front, hidden by the control panel. Here they are:
To get to them, you must first move the control panel, and for this, respectively, unscrew two more screws that hold it from below. To see them, you need to open the oven door and look at the panel from below:
After unscrewing them, we move the panel to the left, since it also adheres to the plates in the form of hooks, and then down. Thus, we get the opportunity to disconnect the hob and turn it over for more convenient inspection.
Visual inspection and check with a multimeter showed that the coil of the burner is intact, all the wires and contacts are also working, the switch is working properly and, when switched on, supplies 230 V to the contact group of the burner, but the current does not reach from the contact groups to the spiral. Therefore, the problem is in this box. , more precisely, inside it:
I had to disconnect the burner fasteners and remove the necessary one in order to unfold the body of the contact group with the face. The burners are held by a metal plate on two self-tapping screws. I didn't take a photo - everything is clear there.
Clever manufacturers made the case disposable, that is, plugged the front surface with a piece of heat-resistant insulator and secured it with a rivet. The type is out of order - take the entire burner with a contact group for 2-3 thousand rubles. Yeah, right now! With gentle rotational movements, the plate was removed intact and the following picture was revealed:
The contact that the screwdriver points to is already slightly cleaned, but initially it was covered with black carbon. in fact, this was the reason that the current did not reach the spiral. The contacts were cleaned with emery, after which everything was assembled in the reverse order.
As a result, the hotplate works again.
The hob is one of the most important appliances in the kitchen, and, like any other technique, is prone to breakdowns, but making repairs with your own hands is quite simple. If a malfunction is discovered during the warranty period, your stove will be repaired free of charge. But if a breakdown occurs several years later, you can try to repair the hob with your own hands, since contacting specialists can cost a little less than buying a new stove.
In this article, our experts have listed all the malfunctions of the hob and step by step disassembled the process of repairing malfunctions with their own hands.
The hob does not turn on - the most common malfunction of electrical panels, the device is plugged into the outlet, but does not work at all, or only one of the burners does not heat up. DIY repair can be disassembled into the following steps:
We check the voltage in the outlet; due to heavy loads, the contacts of the outlet often burn out.
We check the plug and cord for mechanical damage - they can simply shorten or even break the chain. Most often, damage is observed at the points where the panel is plugged into the outlet. Found damage - we replace the cord.
We turn off the power, remove the fasteners and dismantle the surface from the tabletop. We disassemble the surface and move on to the next step.
We take a multimeter and check the transformer, the next step is to check the thermal fuse. In the absence of resistance, or if it differs significantly from that declared by the manufacturer, parts must be replaced, they are sold in many electronics stores.
One hotplate on the hob does not work - it is necessary to check all the wires, as well as their connections to the burners, thermostat, switches, control panel for the fact of an open circuit. If the malfunction is not visually visible, all the contacts are in place, we take a multimeter and check each connection.If you do not have a multimeter, you can use an indicator screwdriver for repairs, with which you can check the presence of voltage on all parts of the circuit. We also recommend watching a video that will help you repair the hobs yourself.

Although induction panels are the most modern and high-tech devices, they are also not immune to malfunctions. We will analyze the main malfunctions of induction panels, and what repairs you can try to do yourself.
The induction hob does not turn on or turns off immediately - most often this is a feature of this type of panel, and not a malfunction. The induction hob has a protective function, if you use the wrong diameter or material of the cookware, the hob will automatically turn off the power, and the hotplate will not heat up. Also, the hotplate will turn off automatically if you remove the dishes from the surface.The induction hob heats up for a long time and weakly - again, we read the requirements for the dishes in the instructions. 90% of induction hob malfunctions are associated with the wrong cookware.The induction hob turns on automatically although there is no cookware on the hotplate. Remove all metal objects and clean the stove from salt, if this does not help, you have a problem in the control unit, it needs to be repaired or replaced. Better to contact the service.The induction hob does not work ... The principle of diagnostics and repair does not change, specialists first of all check the fuse. then they ring the entire chain for an open circuit and replace the burnt-out part.
The last type of cooking appliances is a gas surface. One of the simplest and easiest to repair with your own hands. Less electronics are used, so there are not many faults and everything is easily eliminated.
Gas does not ignite or ignites poorly. We immediately check the electric ignition (piezo) for the presence of blockage or liquid. In 90% of cases, it is enough to wash it thoroughly and dry it. If this does not help, we check the presence of electricity in the circuit leading to the piezo coil.
The gas hob does not turn on because gas does not flow to the burner. Repair of hobs in these cases is not needed, prevention is enough. We check the gas pipe, if the valve is open and there is gas in the system, proceed to check the nozzles. The clogging occurs with fat or food debris, it is enough to clean it. Do not forget to wipe dry after cleaning, moisture should not remain. If moisture remains, the piezo will not ignite.
Modern hobs are equipped with sensors for detecting faults and diagnostic modules, an error code appears on the screen. We find the code in the instructions and follow the specified recommendations to eliminate a specific malfunction. Use the forums, there you can find real reviews and experiences on DIY repair from specialists and other users, namely your model with detailed instructions and photos.
If we analyze all the malfunctions of hobs that may occur during operation, we can say with confidence that most of them can be repaired by hand.
Fuse blown
Contact broke
The chain is broken
Cable damage
Clogged stove, nozzles
The heating element broke
Sensor does not work
All these malfunctions are eliminated by hand, if you are faced with a more complex problem and are not sure of your knowledge and strength, contact the service center.
The hob has long been an integral part of any kitchen. It takes up much less space than a stove, but at the same time it is endowed with a large number of convenient functions and options. But any, even the most reliable and high-quality, equipment may fail sooner or later. For example, the Lg or Bosch hob does not turn on. If this happened during the warranty period, then you need to call the master from the service center or take the technician for repair on your own.If a malfunction is found after this period, you can try to reanimate it yourself, before contacting qualified specialists, whose repair services will be very expensive.
Check the voltage at the outlet. In some cases, heavy loads on the contacts can occur here, which leads to their burnout.
Important: not every home has such special equipment as a multimeter. In this case, you can use an indicator screwdriver to fix the malfunction. It will help you quickly determine if there is voltage anywhere in the circuit.
There are several basic electric hob faults that are easy to fix at home. These include:
The fuse is blown. This usually happens as a result of a sudden power surge. If the cause of the malfunction lies in this, then it will not be difficult to fix the equipment with your own hands. Fuses are sold in most specialty stores, and the price remains low. To protect your hob from such repairs in the future, you should also buy a device that protects the equipment from sudden voltage surges.
Failure of one or more burners. If this malfunction is detected, then first of all, you should check the wires that transmit voltage. Very often, from constant exposure to high temperatures, the heating element could melt, which led to incorrect operation of the burners. The solution to this problem is very simple: the wire is soldered back using a soldering iron. If the electric heater is burned out or melted, then it must be completely replaced.
The problem of the correct operation of the sensor
In addition, the electric hob could fail as a result of mechanical damage. Most often this happens with a glass-ceramic surface, which is considered one of the most fragile and sensitive to external influences. In order to disable the equipment, it is enough to drop an object weighing over 2 kg or a sharp knife on it.
Important: it is very difficult and expensive to repair the panel on your own in this case, so the owners usually contact service centers or buy new equipment. To prevent this, you must be very careful with the hob with a glass surface.
Old and simple equipment is being replaced by modern high-tech models. First of all, these include models that work on induction. But even they are not immune from various malfunctions and breakdowns. Some of them can be corrected quite simply and quickly on your own at home. Among them:
The hob will no longer turn on. Also, consumers are faced with the problem that the equipment turns off abruptly after starting work. If a person uses an induction hob for the first time, then he may simply not know some of the features of this equipment. It does not turn on or quickly turns off due to a protective function that is triggered if unsuitable dishes are placed on the surface. This applies to both its size and material. That is, this is not a breakdown or malfunction, but simply a distinctive feature of this type of equipment. In addition, the equipment will automatically turn off if the dishes are removed from its surface.
The stove does not heat up very well, or this process takes too long. First of all, you should check if the dishes are correctly selected. The induction hob in 90% of cases does not work well for this reason.
The surface does not heat up
The hob switches itself on
Important: if the induction panel stops working or does not work correctly, the diagnosis of faults should first of all begin with checking the fuses, after which, if necessary, the entire circuit is examined for breaks. If they are found, replace the burnt-out element with a new part.
This kitchen appliance is considered one of the simplest types of cooking appliances. In the event of a breakdown, it is easy to fix it yourself at home, as there is much less electrics here than in other hobs. The most common malfunctions are as follows:
The gas will not ignite. First of all, you should pay attention to the work of electric ignition. This part is also called a piezo. In most cases, accumulated dirt or food debris will cause this malfunction. Therefore, in order to eliminate it, the part should be thoroughly and well washed, then dried and reinstalled. If this did not give positive results and the gas is still poorly or does not ignite at all, then it is necessary to check the entire electrical circuit. If a break is found, it should be repaired.
Gas does not flow to the burner. This becomes the reason that the gas hob does not turn on, that is, it cannot fully work. First of all, it is worth checking the pipe through which the gas moves. A person may simply forget that he himself cut off the gas supply, for example, during a vacation or business trip. If the valve is open, then it is necessary to check all the nozzles. Usually, the gas cannot fully flow to the equipment due to the fact that they are clogged with food or fat deposits. Simple cleaning measures will quickly correct the situation and the equipment will be able to function normally again.

If the apartment has a new generation of hobs Lg, "Ariston", Bosch, regardless of the model, then they are already equipped with a special display, which reflects all the faults. When an error appears on the screen, you just need to look at the instructions, what it means, and make a decision on how to fix the problem.
