Happy owners of glass-ceramic stoves are usually very satisfied because the device saves energy. And also by how accurately and quickly the temperature of the burners is controlled.

However, this species kitchen appliances There is one weak spot - the hob. It is a layer of special heat-resistant glass, which can crack under certain conditions.

Cracks on hob- one of the most common failures of glass-ceramic stoves.

Causes of defects

The main cause of damage is heavy objects falling onto the hob.. Usually this happens when a frying pan or pan falls out of your hands.

However, it also happens differently: induction hob For a long time he endures all the vicissitudes of fate. And then suddenly it cracks for no apparent reason. This is due to the fact that destructive loads in the past led to the appearance of microdamages in the material, not visible to the eye . And at some point the inevitable happened, after which the glass-ceramic hob could not stand it.

Important! Additional source The risk for hobs is the use of the wrong detergents when cleaning them.

It happens when using abrasive materials that scratch the surface. Although the damage may not be visible to the eye, it will eventually make itself felt.

If glass panel cracked and needs to be replaced. Let's figure out how to replace glass on a hob.

Replacing the hob

People faced with such a need often have a number of questions. We have prepared answers to them.

Where to go to replace the hob

Have you discovered that the glass has broken or cracks have appeared on its surface? And don't know what to do? To change the panel, you should contact a specialist!

There are special service centers for repairing household appliances.

These may be representative offices of the companies that manufactured your stove. Large brands such as Hotpoint, Bosh, Maunfeld always have branches in all major cities.

You can also contact one-stop repair centers household appliances . They work with a wide range of breakdowns of products from different companies.

Important! Before turning to any service for help, make sure that it has direct access to the manufacturer of your electric stove.

After all to replace the hob, you need to use a branded glass-ceramic panel. These are not sold in the public domain, therefore, they can only be purchased from the manufacturer.

How to replace glass

Installing a new hob Replacing the one that is cracked occurs according to the following algorithm.

Application

You can usually leave a request at the service center remotely. For example, by phone, with an operator. He will tell you exactly when to expect the master.

Diagnostics

A damage assessment is always carried out before starting work.. Even if everything seems obvious to you, there may be some hidden pitfalls. It is better to trust a specialist in this matter.

Coordination of upcoming work

After diagnosis the technician tells the client what exactly needs replacing. It also clarifies what procedures need to be done and how much it will cost.

The next stage will begin only after you find out all the details and agree with the plan for the upcoming repair.

Repair

If we are really talking only about replacing glass that is cracked, then the process will take several hours. From the outside it looks quite simple. However, it requires the use special equipment, branded parts and good skills.

Reception of work

The final part of this whole process is to check how the surface works.

Important! Keep in mind that service centers usually guarantee their work for a period of 1-2 years, depending on the specific company.

Surface replacement cost

The figure consists of several main components: the price of the necessary spare parts, the cost of work. There may also be an additional surcharge for urgent repairs. But service centers usually carry out diagnostics free of charge.

Firstly, the price of spare parts is taken into account. It depends on the specific company, producing kitchen appliances. AND sometimes equals approximately from 10,000 to 19,000 rubles. Secondly, the complexity of the work being performed is assessed. Direct price repair work usually in the range of 2.5-4 thousand rubles.

Thus, the cost of replacing a hob is approximately 50-60% of the price of a new stove.

Is it possible to replace the panel yourself?

This question usually arises in people’s minds immediately after they get acquainted with the cost of the work. She's really great. However, this is exactly the case when the stingy pays twice. Trying to save money and install a new glass surface on your stove yourself can be very expensive for several reasons.

Difficulties with finding and purchasing a new glass surface

These are not for sale in the public domain.. It’s difficult to find an analogue - Regular tempered glass will not work here. After all, it is not intended for specific point thermal loads that characterize the operation of a glass-ceramic stove. Therefore, it may unexpectedly burst or even shatter into many small fragments. It is imperative to use a branded hob.

Sometimes old panels from devices of this type that have become unusable are sold as spare parts. Their use for repairs is less dangerous.

However there is no guarantee that a used panel installed today will not become unusable tomorrow. After all, it was probably subjected to a variety of loads during operation. Most likely, cracks on such a surface will appear very quickly. This means that you will again face the need to replace it.

Replacement work requires special skills and equipment

This process takes relatively little time and therefore seems simple from the outside. But this is not so; it requires considerable qualifications. If you are inexperienced, you can break the slab. Or incorrectly assess the essence and causes of the breakdown.

Important! If cracks or other defects appear on the hob surface, you should contact a good service center.

Only professional masters will provide you with a guaranteed successful result in the shortest possible time.

Hi all.

I decided to write about this, because this happens to many people, but there are either no solutions on the Internet, or I haven’t found them.

I’ll say right away that the most correct thing would be to change the glass or surface assembly, but if this solution does not suit some of you (like me), then this post is for you.
It will most likely not be possible to return the surface to its original state and mask the crack, but “leaving” it in service is fine.

I have top model Bosch induction with infrared sensors temperature control, so I really wanted to keep this particular panel (especially since they are no longer on sale now). The dealer asked 25 thousand for the glass, which is a little... expensive. For this money you can buy a full-fledged panel. So I decided to try gluing it together.

A little information about glass ceramics: it is not glass, or rather not ordinary glass silicate glass, and quartz glass. And the properties of quartz glass are different. For example, it can be locally heated to high temperatures and immediately cooled (even tempered glass will burst), and glass ceramics can also be processed.
From this follows the method of soldering quartz glass. For example, crushed silicate (ordinary) glass. Since quartz can withstand temperatures up to 1200 degrees, and silicate melts at 600 degrees. It didn’t work out for me, because when filling the crack dry, the burner flame simply blows out the crushed glass, and when using a liquid base, I used silicate glue, the silicate glue simply boiled from the flame, foamed along with the crushed glass, and again, the soldering did not work.
I gave you the information - whoever wants it, go for it.

Adhesives that have satisfactory adhesion to glass:
1) Cyanoacrylate (superglue). will not suit us in any way, since the maximum temperature of use is 80 degrees
2) Epoxy resin. can be used except for heating zones. temperature up to 280 degrees, but when heated it releases toxic substances
3) Silicate glue (stationery, liquid glass)... everyone knows glue from childhood. Almost perfect for our needs! we will use it
4) Silicone sealant- temperature up to 200 degrees. there are heat-resistant options with temperatures up to 300 degrees, but they only come in brown

I’ll say right away that I used all three suitable options.

I started with silicate glue. The initial result pleased me, but... the seam did not pass the load test. In the end, I did this: first I used silicate glue along the entire length of the crack, then I strengthened the rigidity in three places (where there are no burner zones) by gluing pieces of ordinary glass onto the silicone, and then I restored the missing fragment epoxy resin, simply pouring it in there (at the same time gluing in another small area of ​​aluminum, since there was a web of cracks in this place).
I’ve been using it for almost a week now: everything is ok, except aesthetics. At the same time, I’m looking through Avito in the hope of finding a similar (similar) panel.

Installing a hob into a countertop

In this final article in the series on installing a hob and stove, I will look at aspects related to the countertop, as well as preparing the countertop and hob for installation.

Of course, the most simple option— at the stage of ordering a kitchen, for a small amount, make a hole for the hob by the company, but for this you need to know the dimensions of your equipment. Therefore, it does not always make sense to immediately order a hole in the countertop. A little advice! Do not make holes until you purchase the cooktop. Always make a hole only using the equipment available!

Hob sizes

Although there are certain dimensions, there are also certain tolerances. Let's start with the fact that the minimum width of the hob is 30 cm. The maximum width can be more than one meter. This depends on the manufacturer’s imagination and the location of the burners (for example, not in the form of a square or some other combination, but in one row). However, the standard length and width of a four-burner hob is 60x51 cm. But these are the dimensions of the top part of the hob. The landing hole itself can vary from 57 to 59 cm in length and from 47 to 49 cm in width. The exact size of the mounting hole can always be found in the operating instructions. The maximum error tolerance is also indicated there. Most often, it is allowed to make the hole 1 cm larger in length and width. But keep in mind that if the hob is not attracted to the countertop, it may move due to big size holes. There are panels (for example Bosh) whose fastening mechanism is generally tricky.

Tolerances with this method of fastening are more critical and allow no more than 3 mm on each side. Therefore, before making a hole in the tabletop, carefully read the operating instructions.

I don’t see any point in copying here a selection of tips from the instruction manual. But I’ll briefly go over the most common points that concern each hob.

Installing the hob into the countertop - seal.

As a rule, it comes complete with the panel. If it is not available, then theoretically you can use any thin door or window seal. Thin due to the fact that, on the one hand, the gap between the panel and the tabletop should be minimal so that dirt does not get into this gap, on the other hand, it must ensure a tight fit so that water does not leak inside, under the panel. Under no circumstances use double-sided tape or sealant, in general, anything that can stick the hob to the countertop. In theory, the panel should work for a long time, in practice, various incidents happen and the panel has to be removed. Removing a glued panel without breaking it is a very difficult task. And re-installation will be difficult, because you will need to remove the old “glue”.

Installing a hob into a countertop - how to cut a hole for the hob

The first step is to make markings with a minimum tolerance. It is very important to maintain a right angle. I usually use the hob itself for this purpose. That is, I draw one line from the near or far edge. I put the required dimensions on it, place the panel along this line and draw two side lines. To avoid scratching the panel, I put some fabric under it. The lines will be strictly perpendicular, then I measure the required value on the two resulting side lines and finish the rectangle. It is very important to pay attention that you do not hit the side walls under the tabletop when marking the hole . Then, as you prefer, use a hacksaw or electric jigsaw a hole is cut out.
To start cutting, you need to drill a hole to enter hacksaw blade. This must be done in the inside of the countertop. The one you will cut out. The photo clearly shows how this is done. Of course, it is more convenient to make the cutout with a jigsaw. Hole in marble countertops or from artificial stone It is advisable to entrust it to specialists. However, you need to remember that the jigsaw pad is metal and can scratch the surface when performing work. To avoid this, you can use
masking tape. Its convenience is that it sticks well to the surface, but does not stick as much as regular tape. You can glue either directly to the marking line or slightly away from it. The main thing is to seal the area that extends beyond the hob, but may fall under the metal pad of the jigsaw.

Installing a hob into a countertop - using silicone

Cutting a hole for the hob (and, in principle, for anything in kitchen countertop) must be treated with sealant. There is absolutely no difference what color the sealant is. In this operation, the most important thing is to properly seal the cut so that moisture does not get into it. Although the countertops are made of moisture resistant material, they still swell when moisture gets inside. Only the cut itself needs to be sealed. You just have to wait a while (from three hours) for the sealant to dry and you can install the surface.

This is where we can end the article. If I remember something, I'll add it. If you have any questions, ask in the comments. Most important points I'll move it to the article.

WITH Best wishes, I!

The requirements for sealants for the assembly and repair of kitchen appliances are outlined. The advantages of heat-resistant adhesive-sealant Dow Corning Q3-1566 are considered, and recommendations for its use are given.

Kitchen appliances and adjacent furniture are often exposed to water and liquid products, which leads to their deterioration and premature failure. To avoid this during industrial assembly, repair and installation of hobs, ovens, gas and electric stoves Particular attention should be paid to sealing connections.

The simplest and most technologically advanced way is to use, which must meet the following requirements:

• the ability to glue and seal various materials in any combination;
• heat resistance;
• durability.

The use of sealants made on the basis of organic polymers leads to reduced reliability and a shortened service life of products. Therefore, manufacturers of kitchen appliances recommend using special high-temperature sealants that can work for a long time and have excellent adhesion to various materials.

Special heat-resistant silicone adhesive-sealant satisfies a wide variety of sealing requirements at the stages of assembly, repair or installation of kitchen appliances. Curing at room temperature, it turns into a durable, rubber-like solid with exceptional performance.

Advantages of high temperature sealant:

• has high adhesion to various materials;
• has the consistency of a paste and does not drip when applied;
• hardens at room temperature;
• maintains stability and elasticity in the temperature range from -50 °C to +275 °C with short-term increases up to +350 °C;
• resistant to chemically aggressive substances;
• released in various options packaging – 310 ml, 20 l, 190 kg.

One-component heat-resistant sealant Silicone-based lasts longer than conventional sealants, guaranteeing the quality and durability of kitchen appliances.

They are popular: they have heat indicators, are easy to use, and easy to care for. But often due to severe mechanical damage or prolonged heating, defects such as cracks and scratches occur. The amount of damage can vary - from a barely noticeable crack to cracks that occupy the entire surface area.

Crack on the hob

• lead to malfunctions of the device;
• the filament temperature rises;
• the external data of the equipment is damaged;
• fractures may increase, which will lead to complete destruction of the glass-ceramic layer;
• the stove can transmit electric current and injure a person.

Causes of damage to the hob surface

If cracks were found on the hob, then this was preceded by the following factors:

• A sharp, strong touch to the surface of any objects. For example, you may drop a heavy pan, which is a common cause of glass ceramic failure. The fracture will look like a hole in the center, where hit, and branching cracks.
• The stove became very hot due to several burners operating at full power for a long time. Usually the defect appears with a bang and can spread in different directions.
• It happens when the stove was installed incorrectly, and the powerful voltage supplied to the equipment destroys the hob. The surface begins to crack from the central part, after which the defects diverge, having sharp corners.
• Point damage, for example, a knife falling.
• Tearing off dishes that are stuck. For example, a frying pan or saucepan was placed on a sticky, uncleaned cooking surface. When heated, the dishes become glued and can only be torn off with a piece of glass ceramic.
• Escaped jam and sugar syrup are very difficult to remove from the stove. When heated sugar comes into contact with the surface, it penetrates into the structure of the glass-ceramic material. When cleaning the slab, the surface is damaged and chips appear.

Important! The last two reasons are caused by manufacturing defects and non-compliance with the rules when assembling the model. Common cases are when the surface is mounted very close to the edges, and during the heating process it bursts.

It should be remembered that faulty equipment powered by electricity is dangerous for any use. There are rules where safety must be observed:

• Any cooking on panels that have cracked should be avoided;
• Cleaning products for cooking surfaces must be specially designed;
• It is not recommended to touch metal utensils wet hands, there is a risk of electric shock;
• Do-it-yourself repairs may result in a short circuit.

What to do if damage such as cracks and scratches occurs?

To get rid of such troubles as a large chip or crack, it would be safer to replace the hob with a new one. Leaving everything as is is also not a suitable option, because the integrity of the equipment is compromised, and the chip can turn into a large fracture. Gluing a panel with your own hands is the most economical way. To do this, you will need a material that will maintain the strength of glass ceramics and will not allow cracks to spread further, and will withstand high temperatures.

Step-by-step guide: how to independently seal a cooktop that has a crack or chip.

Tools and materials:

• Silicate glue.
• Silicone.
• Rectangular pieces of glass, approximately 4x9 cm.
• Epoxy resin.
• Rubber spatula.
• The plate is made of aluminum, the size is selected in accordance with the dimensions of the crack.

How to remove scratches from a stove surface

Appliances with a glass hob require special care. If you do not follow the instructions for using the device, scratches may occur on the stove.

You can remove scratches from the plane in the following ways:

If more serious defects occur, it is better to contact a qualified technician. It is recommended to check the warranty period; if it has not yet expired, you need to photograph the damage and call the service center:

1. You will need to call a repair specialist to your home to conduct an inspection and make a conclusion whether the surface can be restored.
2. If the warranty period has not yet expired, the surface must be taken for examination, which will determine the cause of the destructive impact.
3. If the defect turns out to be a factory defect, the manufacturer is obliged to replace the glass-ceramic element or the entire stove.
4. When the warranty is no longer valid, you should visit a service center or repair shop.
