Kitchen equipment is now in every home, some people only use a mixer and a toaster, but most housewives have modern food processors that perform all functions at once. They are able to speed up a number of complex and labor-intensive processes, perform a variety of cutting and grinding, and easily mix a cocktail or knead dough.
Thanks to such food processors, there is no need to buy a dozen different devices in order to completely cover all your cooking needs. But one device has one motor, although some Bosch models have two. This means that the breakdown of this part can lead to complete paralysis of all work in the kitchen.
Bosch food processor repair - we identify possible problems and fix them
Causes of food processor malfunctions
This type of equipment has a lot of components and it is quite difficult to determine exactly what is broken. First of all, if the unit is under warranty, under no circumstances should you disassemble it yourself, so as not to violate the terms of the service agreement (see also the article Professional kitchen equipment - a fantasy that is always with us).
It’s worth washing it thoroughly, collecting all the documents that came with it and taking it to the nearest branded service center.
Advice: if the owner does not know where to take the broken unit, it is worth carefully studying the warranty card. It must have the phone number and address of the repair center.
However, there are cases when the combine breaks down after the end of the warranty period; in such a situation there are two logical solutions:
- take it to a repair shop;
- try to eliminate the causes of the malfunction yourself.

Frequent problems with Bosch equipment
To find out the cause of equipment failure, you need to carefully disassemble the case and inspect all internal parts. Perhaps the problem is in one of the plastic parts, which is easy to change with your own hands.
You can purchase individual spare parts in a specialized store or in repair shops where used combine harvesters are dismantled. The main advantage of self-replacement is the low cost of repairs.
The most common breakdowns include:
- burnt out engine - the device will not work at all;
- problems with engine parts or a special control board - the combine makes unusual noise, smells of burnt wiring, or turns off from time to time;
- Some attachment or lid lock may break.
After disassembling the case, you need to set aside all the parts that look faulty. Burnt and broken elements must be replaced with new, original or similar ones.
If the fault relates to the electronics section, for example, the control board is not functioning, it also needs to be changed. But without special equipment and knowledge, this will be quite difficult to implement.
Harvester disassembly diagram
- Disconnect the device from the network. If the detailed instructions are not lost, we check the list of parts and check them sequentially.
- We check the drive shaft, gearbox and electric drive.
- Then comes the turn of the juicer, the main mixer disc and all the attachments.
- We check the remaining parts - gears, containers, switches and brushes.

Design and types of food processors
Regardless of the model, the main elements of any unit are:
- electric motor;
- control Panel;
- receiver where products arrive;
- the compartment where the ingredients are processed;
- various knives, attachments;
- electrical wiring connecting all components of the system.
The materials usually used are durable, high-quality plastic for the body and stainless steel for the manufacture of internal parts, which bear the entire load during operation.
In general, all devices are divided into three categories:
- Mini devices;
- Compact devices;
- Multifunctional units.
The functionality of the device and the additional parts included in its composition depend on the specific type. Regardless of the variety, they all work on the same principle: the ingredients are loaded into the compartment, after which the appropriate program is selected and the device starts. The motor is the main element that bears all the load and responsibility for processing the components - it causes the shaft to rotate, driving the attachments.
Interesting! A multifunctional food processor can replace many kitchen aids - a blender, chopper, meat grinder, juicer, and so on.
If the problem is in the brush
Replacing the entire motor at once can be very expensive, the price for such a service is quite high, and it can be difficult to purchase the part itself in small towns. On the other hand, if during disassembly it turns out that it is not the winding or control board that is faulty, but an ordinary brush, the cost of such repairs will be a pittance.
Most often, a malfunction of the brush is expressed in abrasion, after which it no longer presses tightly against the rotor winding, which is why the plastic can become very hot and can smell burnt when starting the combine.
Attention: the brush is a part made of graphite and transmits current to a rotating shaft located in the rotor. Since graphite is quite soft, it can quickly wear down with regular use of equipment, so it must be replaced periodically.
The dimensions of this part are about 2x1x0.7 cm, they may vary depending on the model.

How to replace the brush
- In a specialized store, repair shop, or on the market, we purchase a new brush for Bosch. You can go to a car store where you need to buy, for example, an inexpensive Zhiguli brush. It has a pressed-in conductor made of copper and will last much longer than a simple graphite one, but it will have to be “adjusted” using a needle file.
- We insert the modified or branded part into its place: into a special rectangular hole, where the part is clamped with a metal bracket.
- We assemble the housing and check the operation, first at low speeds, and then at full power.

Possible causes of failure
Despite the variety of functions, any device, such as a Kenwood food processor, consists of five main parts:
- engine;
- food receptacle;
- container for processing products;
- a set of knives and other attachments;
- control Panel.
Failure of any of them entails the main causes of the malfunction. They are of both mechanical and electrical nature.
Food processor parts may fail unexpectedly
The first type of malfunction is manifested in the fact that rotational motion is not transmitted to the working element. This happens for one reason.
- If your cooking aid, such as a Moulinex food processor, has a belt drive, then the belt has broken.
- When a household appliance, such as a Philips food processor, has a direct drive, the lack of rotational movement indicates that the key on the rotor shaft has worn out.
Important! If the device operates unevenly, it means that the drive belt is loose and needs to be tightened. If this is no longer possible, the part will need to be replaced.
Problems with the electrical part can be either minor, such as a blown fuse, switch or power cord, wear on the motor brush, or more serious, when the motor fails and requires rewinding the armature, replacing the commutator or control board.
Other kitchen equipment breakdowns
Almost all breakdowns not related to the operation of the motor can be divided into two groups:
- a plastic part broke: lever, switch, latch;
- the knives became dull.
If replacing plastic elements is extremely clear - bought, installed, started, then sharpening the blades of combine knives with your own hands is a rather labor-intensive and demanding process (see also the article on Japanese kitchen knives).
There are three main methods for this procedure:
- We take the device or just the knives to the nearest service center, where they sharpen them. The result will be guaranteed and quite inexpensive.
- You can use an abrasive stone for turning. But you need to be careful, any wrong angle when pressing can break off a piece of the knife or make it even duller.
- Craftsmen also use regular sandpaper, preferably size 5. But working with sandpaper is even more difficult than working with a sharpening stone. The result will be fast, cheap, but not always of high quality.

DIY food processor repair
Today, food processors from Bosch and many other manufacturers have become almost indispensable devices in the kitchen. There are various modifications of these units that allow you to perform various tasks without you making any special efforts. For some housewives they have become very important, and any breakdown in the system becomes a serious problem. In this article we will tell you about the structure of the device and how to repair food processors with your own hands.
Kitchen appliance care
To avoid having to urgently shell out a large amount of money to repair your equipment, you should take care of proper care in advance (see also the article on cleaning the kitchen).
There are several simple rules to extend the life of any kitchen appliance:
- After each use, all parts should be washed with warm water, if necessary with detergent, and wiped dry. This will allow the knives not to become dull for a long time, and the plastic parts will shine like new.
- The main compartment of the housing where the motor is located just needs to be wiped with a damp cloth to prevent water from getting inside.
- Once a year, after the end of the warranty period, you need to disassemble the combine and check whether any parts have started to burn or whether the brush has worn out. If you change a “weak” part in advance, it will not cause damage to other elements. How to disassemble this or that model of combine can be seen in numerous videos on the Internet.
Signs and causes of malfunctions
Combines are divided into several types:
- mini;
- compact;
- multifunctional.
The last type of combines are those in which, for example, there is a combination of a meat grinder and a juicer. However, despite their different functional features, they all have the same operating principle.
After loading the products into the working chamber of the combine, they are brought to the desired state according to a given program. Processes can change by replacing attachments on them and giving the device the necessary commands. The nozzles are driven by an electric motor. Understanding that your food processor requires urgent attention is quite simple:
- new sound effects that the device has not previously produced, for example, squeaks, knocks, rattles and others like them;
- you feel an unpleasant smell of burning wiring coming from the machine;
- cracks and chips have formed on the nozzles;
- the unit begins to work at an uneven pace, or it does not work in the correct mode according to the given program;
- the device does not want to activate and start working.
As for the torque transmission part, some combines use a belt drive to transmit torque to the main working parts. When the device begins to work poorly, it may be time to replace the worn belt. There is also a keyed transmission of torque forces; in this case, the key may wear out, which will also lead to the inoperability of the combine.
There are many variants of combine harvester malfunctions; perhaps some of its internal elements may fail; if one part fails, the entire mechanism may break. There are also cases when problems arise in the wiring of the unit itself, when a short circuit occurs.
