Sadly, modern technology is not reliable. And when it is used for other purposes, the service life is reduced by half. A coffee grinder is a convenient technique that today is available in almost every kitchen of a modern person. It is convenient and quick to prepare an invigorating drink with it. But if in addition to grains in it to grind other solid products, 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 that is inside it. There is always an instruction manual, many just forget about it. There is a lot of useful information and probable causes of failure.
Unit device
Before disassembling the coffee grinder, it is worth understanding 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 for the product is grains. The millstones work according to this principle - they poured the product in one glass, in the other he grinded, and in the third he turned out coffee.
What is worth knowing about the shock type? At the base there are special legs, they disassemble the coffee grains at maximum rotation. If you compare the internal device, it is close to the blender. Grains are placed in one glass, they are ground there, and they are already being prepared in another department.
Functions
Each manufacturer tries to improve their models in order to become competitive in the market. As a result, the protective functions of the motor appear in the construction during the open cover period. There are modes that can crush harder foods, often with sugar.
Timer
The presence of a timer allows you to create the products necessary for use. The longer the procedure, the finer the final composition. If special legs are ground in the work, then changing the distance between them, the coarseness of the grinding is regulated. This is required to create a specific taste of coffee. For example, for the preparation of expresso you will have to use large fractions.
How to disassemble a coffee grinder?
When the device diagram is known, then disassembling the unit will not be difficult. The principle of operation and internal filling of such devices is 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 had a high level of reliability. Therefore, even today you can find such units in the kitchen. They work 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. The 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 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 by a slot, which is fixed at the bottom. Unscrews counterclockwise.
- There is a nut under the knife. It is unscrewed by any available tool.
- The plastic cup holder is removed with the glass.
- The axis remains - it is restrained on the puck, everything is removed.
- The heating plate is fixed with grooves, so a slight pressing and turning is done.
- To remove the switch, you need to shift the spring.
- A protective plate will be visible there - it can be easily removed.
- Next, unscrew the screws, fix the electric wire. After that, the engine is removed.
This is how they begin to repair the coffee grinder with their own hands. As you parse, it’s worth looking at every detail for integrity. On each household unit, the fixation of the knife is performed reliably. If you untear the thread during the promotion, then nothing further will be disassembled. Therefore, it is worth stocking up with lubricating fluids, splashing onto a bolt, withstanding a few minutes and only then continue work.
Many devices produced in Soviet times are suitable for this system of analysis (including millstones for coffee grinders). If the instruction is lost over time, then this recommendation is taken as a basis. When removing the cover, it becomes clear how to proceed.
Important
Do not use force for all unscrew fasteners. Otherwise, you can break the thread, and the further operation of such a device will be in question.
Another model
Today there are modern units that have taken as a basis the principle of operation of Soviet models. They are disassembled according to the same algorithm. Mikma from a Russian manufacturer begins to understand according to the above principle, but exactly before removing the heating plate, and then:
- The bar is no longer removed, but simply shifted.
- Before you remove the conductor, you need to remove the buttons.
- Then the motor is removed.
- There is an oil seal on the engine - it is 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 be removed when the spring is outside.
- To remove the power cord, you need to find two fasteners from below. They get out after the protective pad is removed.
There are other cars created in Soviet times. It’s not so difficult with them, because they work the same way. If something is broken, then parsing according to the instructions will lead to a positive result.
Modern models
There are a huge number of manufacturers on the market who create units with a wide range of functions. Bosch coffee grinders, if something is broken, is easy to disassemble. They differ in models, the simplest is 6003. To disassemble it, you need to unscrew the knife, the thread is easy. When removed, the engine is pulled out after the power cord has been unscrewed. Just gently need to pull on yourself.
Bosch MKM-6000
With this model is not so simple. Masters believe that without help can not cope. Because you need to hold the device in your hands or in a big vice. To do this, it is placed in a horizontal position and without movement. Where the cord is fixed, you need to pry off the bottom with something - a screwdriver, a probe or just a metal stick is used. Having made a small gap, you have to grope fasteners - latches. They are disconnected, but carefully, because the motor is at the bottom. If you let him go, everything will fall out.
When the latches are disconnected, then there will be no difficulties. It is not worth raising 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 a simple principle, others have some kind of nuance. It is worth being patient and not in a hurry. Masters work in the same way. When a part breaks, parts for coffee grinders are not so easy to find. Therefore, you have to contact repair services.
Although, for example, it’s easy to find a knife for a coffee grinder, because products from one model may be suitable for others.
Elementary problems
There are such breakdowns for which a lot of knowledge is not required. Elementary problems:
- Cooking does not turn on.
- The knives went astray.
- Unusual motor noises.
- The power cord is torn.
If the coffee grinder does not turn on, then it is worthwhile to visually inspect it. When all the external parts are in order, you have to look into the engine. It is difficult to cope with a breakdown of this nature with your own hands. Most often, the motor winding burns out - only a specialist will do it.
Many units have bearings and bushings. This is a weak point in continuous operation. If, after turning on the coffee brewing machine, a smell of burning was felt, maybe dust and dirt formed inside. To do this, you need to find the shaft and treat it with alcohol, removing dirt and dust. If corrosion marks have appeared, there are remedies - they process the place of the problem.
Power cord
The power cord may bend and burst. Need a replacement, 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. There are many problems, but the solution is easy to find.
