Hello everyone, induction after a voltage drop (because the apartment still burned out.

Electrolux EHG6341FOK Pnc 949596023 01 hob, after 10 seconds of operation, error E7 pops up
Good day everyone. the hob turns on, and a pair of regular ones works.

Hob AEG-ELECTROLUX 66301K-MN PNC: 949592580, Like E8
Hob AEG-ELECTROLUX 66301K-MN PNC: 949592580 According to the owner.

on the way, but not yet ripe.

scored up to 110nan by Conder. the situation is unchanged.
Today I realized that an optocoupler can also be so depressed. but as luck would have it, there is no replacement. I'll run to the store tomorrow.

I understood the main plus of this forum. It is possible to first write all the symptoms in a logical sequence, and then sleep well and read carefully again. Sometimes the solution lies on the surface.

The replacement of the optocoupler and the catch-up of the C4 Conder to 110 nanometers in total led to the norm of the result.
Thank you all for your feedback.

Repair of the Electrolux hob in Dnepropetrovsk

Electrolux hobs are rightly considered to be of high quality and durable, but even such hobs sometimes require repair. In most cases, control units fail due to the difficult conditions in which the control unit operates. The most detrimental is the effect of high temperature on the components of the control circuit, as well as high switching power. With high-quality thermal insulation of the control unit, the electronics get every chance to work for a long time. But unfortunately, due to the limited space inside the hob, it is impossible to provide such thermal insulation. Even in the Electrolux EHS 60200X hob, the control unit suffers from excessive exposure to high temperatures. In this particular hob, the control unit housing even turned black in the corner from overheating!

The hob came to our workshop for repairs after it started turning off with an E8 error. At first, this error appears only after prolonged use of the hotplate closest to the control unit. Over time, the E8 error began to appear after 20 minutes of using the nearest burner. With such an error of the control unit, it becomes impossible to use the hob, since the control unit is automatically locked and turned off. At the same time, immediately after the error code is displayed, chaotic clicks are heard for some time from the control unit - block
control randomly turns on the burners.Error E8 can occur due to various problems in the control unit, such as burnout of the power filter, overvoltage or short circuit in the supply circuits. By the way, a similar problem has already been encountered in the AEG brewhouse, which, one might say, is the twin brother of today's brewhouse. This control unit uses a switching power supply, which slightly complicates diagnostics. Since in such power supplies there are quite a few components that can affect the stability of the output voltage.

Switching power supply for cooking Electrolux. With the glass removed and sufficient cooling of the control unit, the E8 error does not appear. Which makes it difficult to diagnose and repair.

It is quite difficult to get rid of this error, since the block suffers from excessive heating.
during operation. And also this problem usually does not reproduce when the control unit is checked already outside the Electrolux hob. As a result, in order to return the control unit to normal operation, it was necessary to replace a comparatively large number of components that rapidly “age” over time.

Electric cookers and hobs, which use induction technology for cooking, are today considered the most productive and economical in their class of kitchen equipment. Their high efficiency and reliability is ensured not only by the use of induction currents when heating dishes, but also by the use of modern circuit and technical solutions related to the control of cooking modes and ensuring the safety of the user during operation. At the same time, induction electric stoves, however, like ordinary ones, may periodically experience various malfunctions, some of which can be eliminated independently.

Despite the high reliability of induction panels, the consumer may encounter defects, for the elimination of which it is necessary to first carry out diagnostics and identify the cause of their occurrence. To facilitate this process, leading manufacturers equip their products with self-diagnostic systems that are able to independently indicate the cause of the malfunction of induction hobs (hobs) and inform the owner about this by displaying the corresponding error code on the information display of the control panel.

Unfortunately, there is currently no single classification of breakdowns. Each the manufacturer codes the same faults differently (see the table for examples).

malfunctions

Important! Repair of induction electric stoves in many cases is quite difficult. To make it at home, you need not only the skills of performing plumbing and electrical work, but also thorough knowledge of an electronic engineer.

The user can start the repair on his own only if he is fully confident that he knows how to eliminate the malfunction. Otherwise, it is better to contact the service department.

Due to the high reliability of electronic components, controls fail quite rarely... Most often, the consumer is faced with minor minor malfunctions, which are represented by the following list:

• insufficient heating power;
• one of the burners does not turn on;
• a pair of hotplates does not work;
• the stove does not turn on or turns off by itself;
• the panel hums during operation, etc.

These malfunctions can sometimes occur due to improper operation of the electric stove.

Insufficient heating power for the cooking zones may be due to the wrong positioning of the dishes on the hob, or when its diameter is less than 70% of the heating zone. Also, the problem can be provoked by a loose fit of the bottom of the pan (pans or kettle) to the surface of the stove.

One or more cooking zones do not heat up due to incorrect switching sequence.According to the operating instructions, in order to turn on the hob, you first need to select the desired burner using the sensors, and then set the required power level. In addition, the cookware placed on the heating element must be ferromagnetic.

Induction surface or the stove may make noise when setting excessive power of the heater, if a cookware with a thin bottom is installed or vice versa - made of several layers of metal, as well as because of the small dimensions of kitchen utensils, which are placed on a large burner.

Heaters turn off spontaneously the following reasons:

• if within 10 sec. from the moment of switching on, the user has not performed a single action on the control panel (selection of the hob, setting the power, etc.);
• when the burners work continuously for more than 2 hours;
• as a result of the operation of the timer on which the switch-off time has been set.

Overheating of the hob may be caused by dirt or moisture.

First, you need to make sure that the appearance of malfunctions is not the result of a gross user error, which can be eliminated without resorting to repair. And only then you should start looking for the reasons that caused this or that malfunction. It must be remembered that before starting repairs to induction hobs and hobs, you must unplug the power cord from the power outlet.

In many cases, malfunctions occur due to damaged mains cable... Therefore, any repair begins with checking its integrity. Initially, the condition of the cord should be checked visually, and then using a multimeter (tester). After making sure that the cable is in good working order, you can move on - check the functionality of the fuses and the condition of the contacts in terminal boxes.

The identified defects must be eliminated (replace fuses, clean contacts, change parts that are broken, etc.). And the decision on the further continuation of self-repair should be taken only after starting the self-test program (self-diagnosis) of an electric stove or hob.

Advice! When an error code appears on the display of the control panel, indicating that the stove (hob) is out of order, experts recommend for 30 seconds. disconnect the product from the power supply and then reconnect. If the error code appears again, then the error message is true.

It is quite difficult to eliminate malfunctions associated with defects in the control unit on your own. Such breakdowns include:

• failure of high-voltage transistors and other electronic components;
• microcracks and mechanical damage to the conductive tracks of the printed circuit board of the control module, etc.;
• unstable operation of the fan (it works in jerks, does not turn on and / or does not turn off, etc.).

Important! The fan does not turn off when the maximum heating power of the burners is set, or the air temperature around it exceeds + 50 ° С. A does not turn on if the minimum power level is set, or the air around the device is warmed up by less than + 50 ° С.

If you identify faults that cannot be eliminated on your own, you must contact the service department to call a qualified specialized specialist who has all the necessary spare parts. This will allow you to eliminate the breakdown in the shortest possible time, while keeping the rather expensive unit intact and safe.

the indicators are faulty and the “dead to zero” capacitor at 100nF is the one that stands on the piping of the optocoupler to determine the power supply in the network

No suspicious places were found in the board. Insulate the board? I can't even imagine what is needed for this. Should you install a fan? A bit tricky.

I saw a message about a capacitor on the Internet. You just need to find it on the boards. I dropped one on the board with relays, it turned out to be serviceable.There are no capacitors near the optocoupler. The board is multilayer.

Further:
There are 2 boards in the plate. One with indicators, the second with a relay.

I took out the board with indicators from the stove, so to speak, so that by elimination to understand which board is the case.

Determined that the matter is in the board with the relays.
I put the saucepan on the burner, when the water starts to boil, it turns off. The video shows the re-inclusion of the hotplate.

Next move.
I think I'll take a hot air gun.
I will set the degrees to about 100 and start heating the board with reels with pieces.
Well, in order to at least determine which part of the board to look for.

Today, the popularity of household appliances powered by electricity is constantly growing, but minor breakdowns sometimes occur during operation. The electric stove is present in every modern kitchen - it is the heart of this space. When a kitchen assistant fails, many home craftsmen are interested in whether it is possible to repair an electric stove with their own hands?

Firstly, a home craftsman who decides to repair an electric stove on his own must at least understand electrical appliances, know the elementary fundamentals of electrical engineering and safety rules when carrying out this type of work. Secondly, you need to be sure that you can perform such a complex repair, and most importantly, find and eliminate the root cause of the breakdown. Third, it is necessary to prepare special tool.

When dismantling electric stoves, you will need screwdrivers for various purposes: for a cross or slot, with different thicknesses, the so-called tip specialists. You will definitely need keys - open-end and capscrews, pliers, wire cutters. For internal work in the body of the product, a soldering iron, side cutters, an insulating tape and, of course, a special device for measuring voltage and resistance are useful.

The photo shows only an approximate set of the necessary tools - during work, the assortment of the tools used tends to significantly expand.

The electric stove looks very impressive - it is a complex household appliance, but its design is quite simple, and all the main working elements are in a special heat-resistant housingwhich is made of stainless steel.

The principle of operation is similar to all electrical household appliances: the current, passing through heating elements (TEN), heats them to a predetermined temperature. The stove has several burners on the hob, and their number varies: at least two, and the standard is 4. For example, the budget Mechta 15M electric stove has only two burners and a small oven, and the product of Belarusian engineers Hephaestus has a standard set of burners and a voluminous oven.

Burner structure quite varied. Classics are burners on an enameled hob with heating elements inside, modern ones are solid ceramic surfaces with heaters of various types built into them. Let's consider the main types of burners.

1. Old domestic options are equipped with products cast iron, they slowly heat up and also cool down, creating a steam effect in the kitchen, but they are resistant to moisture and high temperatures.
2. Tubular spirals - they are made from a hollow tube, when heated, such devices not only give off heat, but also promote the circulation of warm air inside their case, which significantly increases their efficiency. These products are very difficult to repair yourself.
3. Hotplates ceramic very simple in design, they are easy to repair at home - a nichrome spiral is placed in special cells in a circle and fixed. In modern models, glass-ceramic solid plates are increasingly used - they are more durable and easy to clean.
4. Halogen devices - these are special burners with a similar emitter, which are installed in different places on the hob.A stove with such burners provides quick heating, in a second, and low power consumption, so they are the most economical, but only professional craftsmen can repair them.

All models of modern stoves to transfer current to the burners use power wire special section, in addition, they are connected to regulators and thermostats, ensuring their protection against overheating.

In different models, the heating level is controlled in different ways: by manually changing the cooking mode or by special timers and alarms that control.

During the operation of electric stoves, users may encounter such typical malfunctions.

1. Sometimes when the product is turned on, burning smell - it is necessary to turn off the stove and inspect the burners, on which the remains of burnt food could remain, which can be easily removed. When there is a smell of burnt plastic or rubber, then you need to call the master.
2. The heating element does not heat up - here is the fault of the burner or the connecting wires, but first you need to check the controls, maybe the contact has gone away.
3. Impossible adjust the optimal temperature heating the hotplate - it is necessary to repair the switch.
4. The hotplate does not heat up - if you have a spiral inside, then it often ruptures from overheating or moisture ingress. In this case, it is very easy to repair the electric stove - replace the spiral, that's the whole repair.
5. The oven is not working well - it is necessary to ring the heating elements, in 100% it is their fault, replacement is required, since they are not being repaired.

Attention! If the electric stove was connected independently, then not a single service will do repairs for free - you have lost the right to warranty service.

The process of finding equipment failure does not depend on the model of the product and the type of hob or the burners installed on it.

First, using a voltmeter, you need to check the voltage. Do not exclude the possibility of the circuit breaker being triggered, the insulation of the wiring may be broken or the reason lies in the outlet... If so, then it is necessary to disassemble it, and clarify the reason.

If the indicator lights up on the control panel, and the stove does not work, then there is no power supply to the burners, which means that you need to disassemble the stove.

The correct operation of the mechanical or electronic control unit should be checked - measure the current flow to the burner terminals with the device.

Check the heating element of each burner to find a burned-out coil.

Inspect all thermal sensors, relays and various regulators.

Our task is to find a malfunction and localize the resulting problem. After following all the recommendations, you will find the reason for the failure of the equipment, and we will tell you how to fix it a little later.

Models of slabs are different not only in external shape, but also in size, design - it is impossible to describe a disassembly algorithm that will fit all products. Common factor for all is the presence of a thermal insulation layer - here you need to work with him very carefully. Users should be aware that the asbestos dust of the gaskets under the burners in older models is very harmful to health - keep this fact in mind when disassembling archaic stoves.

initially the hob is dismantled - it is fastened with screws, if you unscrew them, then it can be easily removed. Under it are the burners, supplying wires to them and mechanical temperature regulators, which are located on the front panel.

All this must be dismantled in order to get to the lower part, where the heating elements of the oven are located.

At a modern electric hob with a hob made of glass ceramics disassembling the case for repair will be different - in order to get inside, you just need to remove the top panel.

Important! Repair of glass-ceramic hobs is carried out only by specialists of the service center - amateurs with superficial knowledge and lack of experience are better off not touching such complex equipment.

Below are the common breakdowns of electric cookers. Some of them can be fixed by yourself, others require professional diagnostics and repair.

If you have a stove with burners, then in order to change them, you need to act according to this method.

1. We unscrew the nut and remove the grounding.
2. There may be a ring or bracket under it that presses the part to the base.
3. The burner is fastened with a threaded connection or simply inserted into a special hole. In the first case, we lubricate the thread with oil and carefully try to unscrew it from the case, in the second case, we pry it with a screwdriver and take it out.
4. If the model is of the old model, then it is better to immediately replace the burned-out burners with modern and economical models that are suitable in size.
   
5. If the burners are in good working order, then the reason for the failure lies in control unit - a large current flows through the mechanical regulators, and carbon deposits can form on delicate contacts, which are cleaned with fine sandpaper.

Here's a step-by-step guide on how to repair or replace a switch on an electric cooker.

1. If there are no clicks when turning the regulator, this indicates that it is defective.
2. There is an original check of its condition: we put the regulator in the middle position, apply voltage to the stove, the automatic protection should work - turn on and off after 30 seconds.
3. Before removing the handles, you must study the instructions - on some models they do not understand (Gefest, Kaiser).
4. First, the control knobs are removed from the outside, then we unscrew the front panel.
5. A bar is installed under it, which must be removed in order to get to the broken regulator.

If the click is inaudible when the relay is turned on, then it is necessary to check for the presence of a signal - if it is absent, the reason lies in the microprocessor itself or in the cascade at the output. To repair an electronic unit, you need to have a schematic diagram and understand the complexities of radio engineering... If there is no knowledge and skills, then it is better to turn to specialists - otherwise you will have to buy a new electric stove.

Modern electric stoves on heating elements quite often use a cascade-type burner thermostat.

Sometimes there is a breakdown of such a regulator, for which an identical replacement can be found. Experienced masters advise to install triac type such a device, you just need to take it with a margin of power and current strength. In some models, it is installed on one board along with a heatsink. When the hob burner is operating at maximum, and the heating control cannot be changed, this indicates that it was the regulator that failed for an unknown reason - it urgently needs to be replaced.

Each user should understand that modern household appliances are crammed with electronics, each model has its own, different from others, nuance of manufacturing and control - mechanical or electronic. Outside interference without special knowledge and skills can negatively affect the delicate filling of electric stoves.
