Sadly, but modern technology is not reliable. And when it is used for other purposes, the service life is halved. A coffee grinder is a convenient technique that today is available in almost every kitchen of a modern person. With it, it is convenient and quick to prepare an invigorating drink. But if, in addition to grains, other hard products are ground in it, it breaks.

When the device fails for some reason, it is not necessary to go to the master, you can try to solve the problem yourself. It is important to know how to disassemble the coffee grinder, what is inside it. There is always an instruction manual, many simply forget about it. There is a lot of useful information and probable causes of failure.

Unit device

Before you disassemble the coffee grinder, you should understand what kind of device it has. There are two main types: percussion and millstones. The main place inside is given to the electric motor, everything else is for the product - grains. Millstone models work onfollowing this principle - a product was poured into one glass, it was ground in another, and coffee turned out in the third one.

What is worth knowing about the impact type? At the base there are special legs, they disassemble the coffee beans, with maximum rotation. If we compare the internal device, it is close to a blender. Grains are placed in one glass, they are ground there, and in the other department they are already preparing.

Functions

Every manufacturer is trying to improve their models in order to become competitive in the market. As a result, the protective functions of the motor appear in the design during the period of the open cover. There are modes that can crush harder foods, often with sugar.

Timer

The presence of a timer allows you to create products that are necessary for use. The longer the procedure, the finer the final composition. If special legs become smaller in the work, then by changing the distance between them, the coarseness of the grinding is adjusted. This is required to create a certain taste of coffee. For example, to prepare espresso, you will have to use large fractions.

How to disassemble the coffee grinder?

When the device diagram is known, it will not be difficult to disassemble the unit. The principle of operation and the internal content of such devices are approximately the same, the only thing is that the assembly may have some deviations. But the Bosch coffee grinder has two assembly options and therefore it is worth knowing which one is in use.

Soviet household appliances were distinguished by a high level of reliability. Therefore, even today you can find such units in the kitchen. They arework effectively after many years and are in no way inferior to their new "colleagues". Therefore, before disassembling the coffee grinder, it is worth understanding its assembly, year of manufacture. Instructions are easy to find for every model, even released in the last century.

Soviet model

The most common model of past years is 3MM. If it does not break, then you still have to clean it and carry out preventive work. In order not to be mistaken, you should know that the works have the following principle:

• Unscrew the knife. It is held on by a slot, which is fixed at the bottom. Unscrews counterclockwise.
• There is a nut under the knife. It is unscrewed with any available tool.
• The plastic cup holder stows away with the glass.
• The axle remains - it is held back on the washer, everything is removed.
• The heating plate is fixed with grooves, so a slight push and turn is made.
• To remove the switch, you need to move the spring.
• The protective plate will be visible there - it can be easily removed.
• Then unscrew the screws, fix the electrical wire. After that, the engine is removed.

This is how they begin to repair the coffee grinder with their own hands. As you disassemble, it is worth checking every detail for integrity. On each household unit, the knife is fixed securely. If you break the thread during unwinding, then you won’t be able to disassemble anything further. Therefore, it is worth stocking up on lubricating fluids, spray on the bolt, withstand a fewminutes and only after that continue work.

Many devices produced in Soviet times fit this disassembly system (including changing millstones for coffee grinders). If the instruction is lost over time, then this recommendation is taken as a basis. When the cover is removed, it becomes clear how to proceed.

Important

Do not use force on all loose fasteners. Otherwise, you can break the thread, and the further operation of such a device will be in question.

Another model

Today there are also modern units that are based on the principle of operation of Soviet models. They are disassembled according to the same algorithm. "Mikma" from the Russian manufacturer begins to understand according to the above principle, but exactly before the removal of the heating plate, and then:

• The bar is no longer removed, but simply shifted.
• Before removing the conductor, you need to remove the buttons.
• Then the motor is removed.
• There is an oil seal on the engine - it is being dismantled.
• There are shock absorbers on the shields, they are removed. Most often they are made of rubber, there will be no problems with dismantling.
• The button will retract when the spring is out.
• To remove the power cord, you need to find two fasteners from below. They unscrew after the protective pad is removed.

There are other machines created in Soviet times. It is not so difficult with them, because the principle of their work is the same. If something is broken, then parse according to the instructionswill lead to a positive result.

Modern models

There are a huge number of manufacturers on the market who create units with a large set of functions. Bosch coffee grinders, if something breaks, it’s easy to disassemble. They differ in models, the simplest is 6003. To disassemble it, you need to unscrew the knife, the thread goes easily. When it is removed, the motor is pulled out after the power cord is unscrewed. Just gently pull towards you.

Bosch MKM-6000

This model is not so easy. Masters believe that without help they can not cope. Because you need to hold the device in your hands or in a large vise. To do this, it is placed in a horizontal position and without movement. Where the cord is fixed, you need to pry the bottom with something - a screwdriver, a probe or just a metal stick is used. Having made a small gap, you will have to grope for fasteners - latches. They are disconnected, but carefully, because the motor is located exactly at the bottom. If you let go, everything will fall out.

When the latches are disconnected, there will be no further complications. It is not worth lifting the bottom with sudden movements, otherwise the Bosch coffee grinder will break. It is not always possible to disassemble it the first time.

Other repairs

In addition to the Bosch coffee grinder, there are other models. Some understand on a simple principle, others have some nuance. Be patient and don't rush. Masters work in the same way. When a part breaks, spare parts for coffee grinders are not so easy to find. Therefore, you have to applyto repair services.

Although, for example, finding a coffee grinder knife is easy, because products from some models may fit others.

Elementary problems

There are breakdowns that do not require much knowledge. Elementary Problems:

• Cooking does not turn on.
• Knives out of rhythm.
• Unusual motor noises.
• Power cord broke.

If the coffee grinder does not turn on, then it is worth visually inspecting it. When all the external parts are in order, you have to look into the engine. It is difficult to deal with a breakdown of this nature with your own hands. Most often, the motor winding burns out - only a specialist will do this.

Many units have bearings and bushings. This is a weak point in constant use. If you smell a burning smell after turning on the coffee machine, dust and dirt may have formed inside. To do this, you need to find the shaft and treat it with alcohol, removing dirt and dust. If there are corrosive marks, there are means - they process the place of the problem.

Power cord

The power cord may kink and break. A replacement is needed, if this is not possible, then you can simply connect. It is necessary to remove the insulation, solder the wires and tighten the tape again. The problems are many, but the solution is easy to find.
