In detail: DIY blender scarlet repair from a real master for the site my.housecope.com.
There are more and more various electronic assistants in our kitchen, and more and more they fail, especially if you save money and buy the cheapest ones. Of course, expensive blender models are not immune to burnout, but according to statistics, this happens less often. So, blender. It can be submersible manual or tabletop. The essence of this does not change much - in both cases we have a rotating attachment (knives, whisk), which is driven by an electric motor located in a molded plastic or metal body of the blender. Control ranges from simple on / off to multiple electronically controlled speeds. To visualize all this - take a look at the blender diagram:
1. Container jug
2. Latch
3. Cutter
4. Spindle
5. Drive shaft
6. Electric motor
7. Locking mechanism
8. Switch
9. Cord
The immersion blender is not too different, and as for possible problems, they are almost the same and boil down to a broken cord, burning contacts, burning an electronic speed controller or an electric motor.
Practice shows that it is the motor that is the weakest link. Typical case: blender Orion ORB-012 stopped spinning after they stubbornly tried to grind frozen berries, despite slipping and jamming. In very many models, the engine can fail if it runs for more than a certain period.
Disassembling this device is difficult for a layman, not everyone will guess that it is necessary to start with the speed regulator cap.

We pry it with a screwdriver and remove it from the rod, and under it are 4 screws that secure the top cover, which in turn closes the board with the details.
Next, you need to pull out the plastic sleeve near the attachment of the nozzle, which covers the electric motor. Only by pulling out the motor can you pull out the speed controller board after it.
A burnt out motor can be immediately understood by the strong smell of burning. Here, medicine is already powerless, there is no point in rewinding the windings, because it will cost more than buying a new blender.
If the motor is still alive, we look at the regulator. It is assembled according to the circuit of a triac phase regulator, which has approximately the following circuit:
As you can see from the diagram and from the photographs, there are two buttons on the body. One connects the motor immediately to maximum speed, supplying a large voltage, and the other turns on the motor through the speed regulator. There is a noise filter at the input of the 220v network, so that when the blender is on, you do not have interference on the radio and TV.
Pay attention to the fuse. If you are lucky, it will be burnt out, and the independent repair of the blender will successfully end there, under the thunderous applause of the mother or wife 🙂 If not, check the correct connection of the plug, the integrity of the cord, the contact of the buttons, the details of the circuit.
A blender is a multifunctional home appliance that is found in almost every kitchen. This is a convenient device that can replace several devices at once. With its help, grind, mix, beat the products. The design of blenders is simple, so they are quite reliable, but even the most reliable technique fails. Consider how to disassemble a submersible and stationary blender, find the cause of the breakdown and do it yourself repairs.
All blenders can be divided into two types - stationary (tabletop) and submersible (hand-held). They differ in design and method of operation, may have different attachments and additional functions.To repair a stationary or hand blender, you need to understand the features of its device.
The hand-held models are long-handled electrical appliances with a cutting attachment. They are dipped into a bowl with products that need to be chopped and mixed, pressed on the start button and held until the procedure is over.
The undoubted advantages of submersible models include compactness. The devices are easy to disassemble for cleaning, plus they need a minimum of space to store them. Blenders with a large number of attachments are versatile and perform a variety of food preparation operations.
There is only one drawback of submersible structures, but it is significant. During cooking, you have to hold the device in your hand while pressing the start button. If you have to do this within 1-2 minutes, the hand gets tired, numb. Such a device is not suitable for frequent use, because does not cope well with mixing large portions of food.
Making Soup with a Hand Blender
Stationary models resemble food processors in appearance and often perform many functions. They are bowls with rotating knives attached to the bottom. Such a device is installed on a table, you do not have to hold it with your hands while working. He is able to grind a large portion of food at a time, copes with mixing cocktails, liquid dough.
Desktop models also have drawbacks. The hostess has to allocate quite a lot of storage and installation space. In addition, some stationary blenders do not grind vegetables well: they either grind into crumbs or remain large chunks. The advantages of tabletop structures include the fact that they are sometimes easier to disassemble and repair with your own hands than submersible ones.
Although the principles of operation of submersible and stationary blenders are similar, there are still differences due to the different design of the devices. In all models, products are chopped with knives, but in tabletop appliances, the bowls also serve as an auxiliary function.
The knife of the stationary appliance, located at the bottom of the bowl, rotates and cuts the food. With an increase in speed, the crushed mass is mixed, rises up. The walls of the bowl expand upward, so small pieces slide along the walls, and large pieces fall into the center - to the knives. It turns out that the crosspiece pulls down the pieces of food and throws the already crushed mass to the walls of the bowl.
It is not uncommon for a blender to be considered broken if it does a poor job of chopping. But it happens that the problem is not in breakdowns, but in the low power of the electric motor. Sometimes it is enough to add a little liquid to the bowl to make the work of the knives easier.
If the model is powerful, then such deviations in operation can really indicate malfunctions, for example, a blunt knife, a broken speed switch, etc. In some cases, problems with the bowl may be the cause of poor performance.
Stationary model device
In submersible structures, collector-type electric motors and fuses are usually installed that turn off the device in case of overload. Frequent breakdown - burning of current-carrying parts, therefore, when a malfunction occurs, first of all, the contacts "ring out" by rotating the shaft by hand.
Care must be taken when using handheld devices: they are not suitable for kneading dough and other thick products. The motor may not be able to withstand the load. Repairs will be expensive. However, there is good news: often women's hands get tired of holding the equipment before the engine has time to overheat.
Many models are equipped with gear shifters. This is a very convenient feature that expands the capabilities of the hostess. But if the engine does not cope, then the working device can break out of the hands, which becomes the cause of mechanical failure.
Submersible model device
In submersible models, the power cable is often damaged. This is the flip side of the main advantage of such devices - mobility. The hand blender is often turned on and off, carried from place to place, which leads to kinks in the cord, incl. critical.
Unstable operation of the power grid is also a risk factor. During power surges, motors often burn, printed circuit boards are destroyed. Often it is necessary to replace the knife, repair the attachment, the speed regulator. In table-top appliances, liquid may leak into the nozzle drive, the bowl snap mechanism may break.
Hand blender repair
Consider how to check the performance of individual structural units:
- If the blender does not turn on, the first thing to check is the presence of current in the electrical outlet. Before disassembling the device for repair, you need to make sure that there are no power problems. The outlet is checked using a tester or by connecting to it another electrical appliance, which has an accurately working cord.
- If there is current, but the blender does not turn on, check the power cable and fuse. Repair in this case comes down to replacing faulty parts with new ones.
- Overloads can burn the motor. In addition to problems with performance, such a breakdown gives off a burning smell. Sometimes the device can be repaired by replacing the brushes on your own, but more often you have to give the blender to a service center for repair or buy a new one.
- When the elements of the printed circuit board burn out, a short circuit occurs. It is necessary to disassemble the equipment, inspect the board, test and, if necessary, re-solder the faulty elements.
- If the gasket leaks, then it must be replaced with a new one. liquid can get on the electric motor and cause more serious repairs.
Diagnostics of malfunctions of the submersible model
Housewives are often faced with a situation where the blender has stopped and the knife is not spinning. It happens that the knife is spinning, the engine and the speed switch are in good order, but when loading the products, the device runs “idle” without grinding them. In many cases, repairs can be done by hand. Let's figure out how to do this.

Before disassembling the blender for repair, you should carefully read the technical documentation. Disassembly instructions may be supplied with Bosch, Philips, Scarlett, Polaris models. It is best to follow the manufacturer's recommendations. Otherwise, there is a high risk of permanently breaking the device.
For disassembly and repair, you will need the following tools:
- flat thin screwdriver (if such a screwdriver is not available, it can be replaced with a narrow knife);
- long screwdriver;
- pliers;
- a magnet to reach small parts if you cannot remove them with tools;
- superglue or any other reliable adhesive with which you can restore the integrity of the seams if they are damaged.
DIY blender disassembly procedure:
- Remove all screws, remembering or noting where they are located.
- Remove as many items as possible.
Note! Some craftsmen offer a more radical option for disassembly: a narrow screwdriver or knife is pushed between the body and the casing of the device and the weld is knocked down with an accurate hammer blow. This method is only suitable for non-collapsible models, and superglue is required to reassemble them after repair.
- Parts that could not be removed must be carefully inspected. They can be clipped. In this case, they can be removed by pressing the latches.
- When the case is disassembled, you can start checking the performance of parts and repairing.
The most common models of Scarlett ("Scarlet"), Vitek ("Vitek"), Polaris ("Polaris"), Philips ("Philips"), Bosch ("Bosch") are usually disassembled, so they can be repaired by hand, replaced nozzles. Let's consider in what cases self-repair is possible.
- Replacing the knife. If the knife is dull, it can only be replaced, because it cannot be sharpened. New knives are sold in specialized and hardware stores. To replace, remove the old part by wrapping a towel around it and unscrewing it. After that, insert a new knife (it may differ in appearance from the old one), secure.
Important! Sometimes you can buy a new knife complete with an oil seal. It makes sense to replace both parts at once. In some stationary models, the knife cannot be removed from the bowl, because it is not collapsible. Then there remains only the option of a complex replacement of the bowl, knife and gland.
Old and new knives
- Speed regulator. In stationary models, it may be difficult to check the switch, because the function of blocking switching on without a bowl is often provided. By the way, the problem of stopping the operation of the device is also associated with blocking. If you suspect a malfunction of the speed switch, it must be evaporated, each position must be checked in full, and repaired.
- Stopping work. If the device does not turn on, the first thing to do is check and, if necessary, replace the cord. If it turns on and buzzes, but does not work, then disable the lock. Inoperability when the blocking is released most often indicates a burnout of the electric motor winding. It can be replaced, but this is an expensive repair, so more often than not it is more profitable to just buy a new blender.
Note! The problem might be with the circuit boards. Capacitors and resistors are worth inspecting. If a short circuit occurs, then it is better to give the device to specialists. In many cases, damaged electronics cannot be repaired or the cost is too high.
So that you have to disassemble, check and repair blenders with your own hands as rarely as possible, you should adhere to simple rules of safe operation. Check the reliability of attachments before starting work, do not turn on the device without a bowl, do not overload, handle the wire carefully (make sure it does not bend or twist). The main thing is to follow the instructions for use. These simple measures are quite enough for the equipment to serve for many years without repairs.
Rack structures on the ceiling are used to decorate various premises, both residential and public. The kitchen is no exception. The popularity of this material.
Someone becomes an adherent of this style at first sight, someone is annoyed by its excessive cloying and "mimicry", but completely indifferent shabby.
The financial costs of arranging a kitchen and a bathroom often account for the lion's share of the cost of repairing an entire apartment or private house. No wonder, after all.
The blender made us put food processors, mixers and other appliances in the back cabinet. But, as is typical for household appliances, the blender can fail. Fortunately, in some cases, breakdowns are not so terrible, and you can repair the blender yourself. How exactly, I'll tell you now.
Before proceeding directly to troubleshooting, it is important to know the very internal structure and the principle of operation of the unit.
The blender itself is a motor of a certain power, hidden in the body of the handle, which we hold by pressing the button and adjusting the speed (manual). Also, the motor can be placed in a stand case (stationary).
A special attachment with a knife (whisk, crush, etc.) is put on the motor shaft, which rotates the knife or rotates itself when the button is pressed.
Something like this looks like a stationary device for grinding products.The general purpose of both types of devices is the same, but in the event of a breakdown, their own characteristics and subtleties of repair appear.
Submersible model with replaceable tipsSometimes for a blender breakage, poor operation of the knife, slipping during grinding, or the presence of large pieces in the ground mass is taken.This is not a breakdown, but a common problem with low-power models, which, due to the limitation of motor power, cannot cope with solid food. If the unit previously coped with harder fractions, then it is worth examining it for malfunctions.
The general device of the stationary blender:
- bowl with a knife;
- motor shaft;
- bowl latching mechanism;
- electric motor;
- switch and speed controller;
- power cord.
The instructions in the table contain a description and solutions to the most common malfunctions of a stationary blender:
Problem: The bowl of a stationary unit may leak where it is connected to the body.
Solution: bowl repair is a simple replacement of the gasket.
Unfortunately, the part cannot be repaired and you will either have to find a replacement one (which is not always possible), or buy a new device.
The device of a portable blender is somewhat different: the simplest models are very compact and consist of:
- handles with an electric motor;
- speed switch and power button;
- legs (elongated attachment with a "skirt" and a knife);
- power cord.
The set can be supplemented with a grinder bowl, attachments for whipping liquid products, making mashed potatoes, etc.
One way or another, for the submersible blender to work properly, it is often necessary to eliminate the following problems:
The cord is a "weak point" of portable models, since there is a much higher probability of damaging it with an accidental sharp movement, passing it with a heavy object, etc.
- disassemble the handle with the motor;
- we check the condition of the incoming contacts, evaluate the internal elements for breakage;
- we connect a new serviceable cord to the contacts and check the functionality.
If the blender does not work, but emits characteristic buzzing sounds or does not switch speeds, then perhaps it is the regulator that is the problem:
- disassemble the case;
- with the help of a multimeter we "ring" the part;
- we solder the part if the problem was detected and each position was adjusted;
- pay attention to the regulator contacts - they must be closed.
Do-it-yourself blender repair in most cases means disassembling the case. Most branded models provide for this, but there are also non-separable models. In the latter case, it is worthwhile to disconnect the housing elements with extreme caution, and use adhesives when reassembling.
The malfunctions from the table below are typical for any type of blender:
The knife in the attachment or chopper bowl may be less effective at grinding, tearing, or seizing pieces during use. Repair of the grinder in this case consists in replacing it, since the knife cannot be sharpened.
How to disassemble the blender chopper:
- press the axis of the knife with your finger;
- pull it up in a rotating motion.
In most bowls, the knives are removable, and if not, then the problem will be solved only by replacing the bowl.
If the knife is blunt in the leg of the hand blender, how do I repair the attachment? In this case, you can either purchase a new one, or disassemble the attachment, replacing only one knife.
If the unit stops working, the problem is probably in the fuse:
- disassemble the case;
- remove the fuse;
- we replace it with a new one (the price of a new part is very small).
If the blender does not spin, although it buzzes and clearly shows signs of life, then this may be a malfunction in the engine winding.
It is not recommended to repair it yourself. Try to get a new engine, otherwise you will have to go to the store for a new blender.
When, it would seem, it was possible to determine the malfunction, change the part, but it turned out that the next time it was turned on to the network, the device did not turn on again, then this is probably a short circuit.
In this case, you cannot fix the problem on your own. Such damage cannot be repaired.
