Blender repair: nozzles, blades, motor, gearbox, lid, legs - find out how to repair it yourself, where to get spare parts and how much it costs

A blender breakdown can happen at any time, but don’t rush to immediately throw it away and run for a new one! If the screwdriver and electrical tape do not fall out of your hands, then first find out whether it is possible to repair the blender in a particular case .

To talk in more detail, let's first understand the types of blenders. Studying the design of the blender will make it easier to disassemble it and further diagnose the breakdown.

Types of blenders and their design

CONTENT

The English word “blender” is translated as “mixer, stirrer.” A blender occupies an intermediate position between a mixer and a food processor. From the first he received whisks for mixing, from the second he received knives for chopping.

This kitchen unit is a fairly simple technique: a motor plus an attachment . There are two types:

Submersible or manual.
Stationary.

Submersible

A long cane-shaped device that turns into a nozzle. It may have several removable attachments, but lacks a bowl. Therefore, mixing, chopping and whipping can be done in any container convenient for you.

Its second name is “manual”. This is due to the fact that he will not be able to work independently without the help of your hands. It needs to be held during operation, which creates some inconvenience.

Its advantage is the ability to process small quantities of products, for example, chopping berries for smoothies or making purees for a child. However, most often this unit is not designed for long-term use, which contributes to rapid failure. Repairing an immersion blender is quite simple . Its body contains:

engine;
spindle;
Control block.

Stationary

In contrast to a hand blender, it can work completely independently. It has a base - a body on which a glass or plastic bowl is attached (depending on the model).

The necessary attachments are installed in the bowl according to your choice, which brings the stationary blender closer to a food processor in terms of functionality. Repairing a stationary blender is a little more complicated due to its larger design and number of parts .

Having your hands free when using this type of blender is a huge plus given our lack of time. However, this kitchen assistant does not cope well with small quantities of ingredients. Often its power is greater, it can work for a longer time without respite, but it takes up much more space than a manual one. It consists of:

bowls with lid;
engine;
spindle;
knife;
drive shaft;
locking mechanism;
switch;
cord.

What parts can fail?

The features of blender repair directly depend on which component has failed. Some parts can be repaired, while others must be replaced.

Filters

Modern types of kitchen blenders have a filter in the lid. Additionally, you can use a mesh filter by installing it in the bowl.

Diode bridge

Budget blender models have one rotation speed, and the electric motor in them is powered directly through a diode bridge. A faulty part causes the engine to slow down or not start. To use the device in normal mode, you will need to perform diagnostics and, if necessary, repair or replace the diode bridge.

Transformer

The role of the transformer in a kitchen blender is to control the voltage level that is transmitted to the electric motor.

Malfunctions in the functioning of the transformer lead to sudden voltage surges, short circuits and internal breakdown of the device.

Generator

The generator is one of the key internal components and works in conjunction with other mechanisms, including the engine. It is possible to detect a generator malfunction only by disassembling and diagnosing the equipment.

Key transistor

The key operating mode of the transistor is one of the simplest and most common. Most of the time, the blender transistor is in two states: cutoff and saturation. A transistor malfunction results in the device not responding after switching on.

Rectifier output diodes

To check the functionality of the rectifier output diodes, a standard testing procedure is carried out. In many types of blenders, the motor is connected via a diode, so the ability to operate the device depends on the correct operation of the component.

Varicaps

Varicaps are semiconductor diodes. They change the capacitance indicator in proportion to the magnitude of the applied reverse voltage.

Circuit breakers

If you use the blender continuously, the fuse may burn out. In this case, it is not allowed to use the device until repair or replacement is carried out. Otherwise, you can provoke new breakdowns.

Elimination of minor breakdowns

Next, you will learn how to repair a blender with your own hands and that this will only require basic knowledge from the field of electrical engineering and electronics, some tools and desire.

Information: there are models of immersion blender with a molded plastic body, the disassembly and repair of which is not possible.

Blender blade repair

It is unlikely that you will be able to sharpen a knife for a blender or chopper yourself unless you have a special tool and the proper experience. Especially if these are knives in a dicing attachment, but anyone can replace a dull knife:

check that the device is not plugged in;
remove the bowl from the stationary blender;
on some models the knife is secured with nuts; remove them using a wrench;
use a cloth to grab the knife;
unscrew, taking into account that the thread is left-handed.

Check the contents of your blender; there may be a spare blade there . Otherwise, buy a new one based on your model.

It is a rare case that you will need to disassemble the bowl to remove the knife. The steps are the same, but it is worth replacing the oil seal at the same time.

And it’s certainly not a repair case - this is not a collapsible bowl . Then you just need to throw it away and buy a new one, but here it is worth considering the price issue. Maybe it's better to buy a new blender?

Cleaning required

Important! Do not put metal objects such as spoons, forks and knives into the blender.

Any cleaning should begin by disconnecting the device from the mains:

carefully remove the bowl from the main body;
unscrew and remove the ring nut, which is located under the blade holder;
carefully release the knife from the stuck object;
check the integrity of the knife (most likely it needs to be replaced with a new one);
wash all parts with warm water using a non-aggressive detergent;
dry thoroughly and assemble;
check the work.

Replacing the knife

Important! You will not be able to sharpen the blade by hand at home.

There are two scenarios here:

Go to the workshop and ask for a knife to be sharpened. However, it must be said right away that most masters will tell you to buy a new one.
Buy a new knife. They are now sold in almost all stores. To do this, you need to know the model, and it is better to go searching with a passport or with the device itself. Most often they are sold together with oil seals, so you need to replace it immediately.

Before starting the manipulation, unplug the device from the outlet, otherwise one careless movement can lead to the loss of your fingers!

Removing and replacing a knife with your own hands

To remove the old knife, you will need a towel. Use it to grab the cutting part and unscrew it from the spindle.

Note! You need to scroll to the right!

In some models, the knife can be secured with several nuts, so you need to arm yourself with a wrench or pliers. Sometimes, but in rare cases, to dismantle the knife, you need to disassemble the bowl.

After replacement, you need to install everything back and securely fix it. Only after this, turn on the device for testing.

Electrical breakdowns

The knowledge gained at school in physics lessons will come to the rescue. You don’t need to have a brain and super gadgets. All you need is basic knowledge and a voltmeter.

Broken wire

Have you turned on the blender and received silence? Don't immediately run for a hammer and screwdriver. Start by checking the voltage in the outlet you need by connecting any working electrical appliance. Is the table lamp shining? Then check the cord:

unplug from the outlet;
ring the wire;
use a screwdriver to disassemble the case;
we find the power block where the wire is screwed;
call, if there is no signal, change the wire;
assemble and turn on.

How to do self-diagnosis at home

If the device fails or does not work correctly, then first of all it is necessary to carry out diagnostics. After the assessment, you will be able to understand whether the blender burned out or not. The check is carried out according to a specific algorithm, which includes the following actions:

Attempt to turn on the device and evaluate the operation.
Disassembling the main removable elements.
Disassembling the case and assessing the condition of internal parts.
Checking the current supply to the main electrical components with a tester.

If you need to get information on how to check the engine, you will need to carefully study the instructions and internal structure of a particular blender. You can find detailed information on the Internet. It is especially important to obtain a device diagram for complex repair work, which includes replacing a switch, soldering wires, or restoring microcircuits.

Important! Professional diagnosis can only be carried out by an experienced specialist. You will definitely need to evaluate the condition of each internal part using a tester.

Mechanical damage

When working in blenders, not only the electrical part suffers. Quite often there are mechanical damages , which can be dealt with independently.

Leaking engine gasket and bowl

Noticed a leak between the body and the bowl? Feel free to start repairing:

remove the bowl from the body;
unscrew the drive spindle;
remove the old gasket;
install a new gasket in its place.

Tip: the spindle has a left-hand thread.

Damage to the lid latch mechanism or attachment

If you use the blender carelessly, you can damage the lid latching mechanism for stationary ones or the nozzle for submersible ones. There is only one solution to the problem: buy a new part , since repairing the chopper lid or blender attachment can lead to injuries during further use.

You can still try to repair the whisk attachment by removing the broken rod. Only during further work, you need to be careful as part of the protruding wire may scratch.

Important! Not all manufacturers have a spare parts market.

Damage to the blender body

A damaged hull can hardly be repaired . Operating such an electrical appliance threatens your safety. Treat yourself to buying new equipment.

Damage to the blender jar

There are latches on the bowl that can break off if not used carefully. If this happens, the engine will not turn on due to the protection being activated. There is only one solution to the problem: buy a new bowl .

If you pour boiling water or other hot liquids into the bowl, the container will be damaged. The solution to the problem is also: buy a new bowl.

Conclusion

If the blender breaks down for any reason, you do not need to immediately contact the specialists. After all, the cause could be a simple cable breakdown or blocking of the knives. Before wondering if the blender is not working, what should you do? Check the elementary possible causes and only after that, evaluate your strengths and capabilities, and only then proceed with independent repairs.

I would also like to say that some spare parts for these household appliances are very expensive. In addition, manufactured non-original spare parts do not guarantee long and high-quality operation. Therefore, before you start repairing it yourself or in a workshop, evaluate its feasibility. Because sometimes the difference between a repair and a new device can be only a few hundred rubles.

Additional Information

How much does it cost to repair a blender? There is no answer to this question because you need to know what exactly is broken.

According to the service center, in 90% of cases it is possible to repair the Braun blender (especially the 600 watt turbo model), Hamilton beach, Philips, Polaris, Bosch, Scarlett, Redmond, Supra, Vitek, Moulinex.

Repair of blenders Kambrook, Mixsy, Maxwell, Saratov, Kenwood, Tefal can be repaired in 60% of cases due to the specific design.

Regardless of the brand, you can easily repair the blender yourself by following the recommendations given above.

Features of disassembly from different manufacturers

When disassembling the device, you need to take into account the design features. Equipment from different manufacturers has distinctive features.

"Brown"

The main feature of Braun blenders is that during disassembly the engine is removed along with the control system. If this does not happen, you need to pull the edge of the board with pliers.

"Philips"

In Philips devices, there is a cover on the back end, under which there are 2 screws for the power cord. They hold the engine and do not allow it to be removed from the other side.

"Bosch"

To disassemble Bosch devices, just use a screwdriver. Having lifted the case and removed the latches, all that remains is to unscrew the screws to gain access to the mechanisms.

"Kenwood"

The process of disassembling Kenwood blenders is similar to unwinding Bosch appliances. Using a screwdriver, you need to break through the gluing area and walk along the entire casing. Then disassembly is continued from the reverse side, prying the regulator handle in several places.

Polaris

When disassembling devices from, you need to unscrew all visible screws. After removing the fastening, it is possible to separate the parts of the housing and gain access to the internal structure.

Vitek

The halves of the Vitek blender body are secured with latches. The main retaining screw is located under the switch, which can be removed by prying with a screwdriver.

Food Processor Complementary Ingredients

The blender, which is an integral part of the combine, is in many ways similar to the stationary model. The device is built into the food processor and has many functions. If repairs are necessary, it may be necessary to partially disassemble the combine.

Replacing the knife

If the knife is significantly damaged, it must be replaced. For most blender models, purchasing a blade is easy because they are sold as separate replacement parts.

How to pull it out

After purchasing a new knife, you must first remove the old one and replace it. The process involves performing the following actions:

When starting to disassemble the device, first unplug the blender from the outlet and remove the bowl.
To avoid getting hurt by a sharp blade, take a clean towel and unscrew the knife from the motor spindle. Since the threaded connection is not standard, the knife must be unscrewed by rotating to the left.
If the knife is fixed in the bowl with nuts, you need to use wrenches or pliers to remove the part.

How to disassemble the bowl

There are models of devices in which to install a new knife you will need to first disassemble the bowl. As a rule, it is enough to remove it from the central mount

It is important not to forget to replace the oil seal with a new one.

If the bowl is not removable

In cases where the design features of the blender do not allow disassembling the bowl, the only way to solve the problem is to replace the bowl along with the knife. You need to choose a bowl that is the right size and fix it in the correct position.

Speed controller

On many blenders, the speed controller often breaks down. Due to incorrect operation, the speed may change during operation or be greatly reduced.

Part removal

In stationary varieties, there is often a problem with checking the switch due to the presence of a switch lock without a bowl. To remove the regulator from the case, you will need to unsolder it and check the condition of the internal components.

Calling

Testing the speed controller helps to find an open circuit or short circuit, which facilitates effective diagnosis and elimination of the problem. For testing, use a special device, a multimeter. It is allowed to ring only de-energized circuits to avoid injury or damage to the equipment. The procedure is performed according to the following instructions:

Fix the probes in the connectors of the multimeter.
Switch on the dialing mode on the device, after which the display should display one.
Check the correct functioning of the multimeter by connecting the probe contacts. If the device is working properly, it will emit a beep.
The multimeter probes are applied to the contacts on the speed controller. If there are no faults, the buzzer will sound and a value close to zero will appear on the screen.

Preparing tools

Make sure you have all the necessary tools at hand in advance. Their list is simple, and you are unlikely to need to run to the store to buy one - these tools are in every home:

pliers;
a flat-tip screwdriver (if you don’t have one, use a regular penknife);
hammer (small size will do);
glue (on its label it should be written that it is suitable for gluing plastic and/or metal parts: usually it is hot melt glue or Moment glue).

All actions to disassemble the blender must be done extremely carefully. The device may simply break under a strong blow from tools, and a crack will appear along the body. This blender cannot be restored.

How to disassemble a Brown blender (Scarlett, Polaris, Philips, Bosch)

We immediately want to warn our readers. If your blender (mixer) refuses to work fully for reasons unknown to you, and its warranty period of use, which is mandatory provided by a trade organization for products of well-known brands of kitchen appliances, in our case - a blender, has not expired, there is no need to pretend to be home-grown Lefty or Kulibin!

Just take it (the mixer) to a service center, where the device will be fixed if you provide the appropriate warranty. If this is not possible due to the fact that the device has honestly and efficiently worked for the period specified by the manufacturer of a well-known brand in the warranty (usually from 1 to 2 years), simply buy a new one. Moreover, these devices are not very expensive, and uninterrupted operation for 1.5-2 years is a very decent period for such equipment.

We will, of course, give an example of how to disassemble a Philips blender (of another brand), but we warn you in advance. In most cases, you are unlikely to be able to assemble the device in its original form. Due to the fact that individual companies (Brown, Philips, etc.) produce disposable models. So, when choosing an answer to the question of how to disassemble a Brown blender, we came across an example in which the user of the named device had to disassemble the blender by sawing it. It was not possible to more accurately divide the device into its component parts due to the fact that some elements of the mechanisms are sealed into the case at the factory and do not imply free access.

How to disassemble a Philips blender

Before disassembling the device, carefully read the instructions supplied with it. Sometimes it indicates how to disassemble a Bosch, Philips, Scarlett, Polaris, etc. blender. Prepare the tools necessary for work:

Various types of ends and screwdriver thickness;
Pliers;
A knife or a hard, thin metal plate replacing it;
Magnet for removing small parts from the case.

Disassembly of the device:

We unscrew all the screws available for this, remembering their location.
We remove the released components of the housing.
We carefully study the elements remaining in the same place. It is possible that they are connected through latches.
Having found the latch locks, carefully press them out with a suitable tool.

As a rule, after this, disassembly of the case is completed, and its mechanism hidden inside is provided for subsequent actions to replace components and assemblies.

To be honest, we don't really understand the purpose of disassembling a blender yourself. Since replacing an engine due to its cost is not a financially profitable operation, as are smaller and less important parts. You will still have to buy them from a company service center. You won't find them on the open market. The only motivation for disassembling a failed blender can only be the user’s natural curiosity or his desire to use the working parts in the future. But already in devices for other purposes. How to disassemble a blender - watch the instructions in the video.
