2. The grinder does not work at all.
It's cheaper to buy a new grinder.
3. The grinder turns slowly.
The recipe for a delicious coffee consists of the selection of a good variety, quality roasting and grinding. If it's a little difficult to do the right roasting, then grinding the grains in the kitchen with a coffee grinder is a simple matter, which the Bork coffee grinder does a good job with. The trade mark appeared in 2001 and quickly took its place in the market of domestic goods for household appliances and electronics. The release of these products has been established jointly with Chinese partners.
The Bork technique is quite widespread in Russia and is in great demand among the population. The assortment of the Bork coffee grinder is represented by millstones and rotary options of different capacities, the largest of which is designed for 450 g of grain. The smallest one holds 75 g. All models share several common parameters:
steel or plastic case;
automatic shutdown, which determines the frequency of the work process;
grinding adjustment from 5 to 25 degrees.
An important positive side of the Bork coffee grinder is that the user himself can set the necessary parameters. This function is quite convenient, it increases the safety of the unit operation. Among the negative sides is the manufacturer's pricing policy. The cheapest model, which can rather be called a simple chopper, costs from 4 thousand rubles. Prices for new generation coffee grinders start at 20 thousand rubles.

No matter how perfect the unit is, it can fail for various reasons. To eliminate the malfunction, the kitchen appliance must be disassembled. It is better to entrust this to a specialist, but there are also those who are able to figure it out on their own. The most common reason for disassembling a machine is to replace the blades. To do this, you need to take a screwdriver and unscrew the fastener located at the bottom of the grinder. Then, moving counterclockwise, unscrew the knife itself and replace it, and then fix the connection.
Any action related to the repair of the kitchen unit must be carried out only after it has been disconnected from the network. There are more complex breakdowns, for example, the Bork cg700 engine does not work. In most cases, the cause is a malfunction of the electronic board. With a similar question, it is better to contact the service center.
I have been using the Bork coffee grinder for several months now. I bought a powerful and expensive model j800, because my wife and I are big lovers of freshly brewed coffee. We are satisfied with the purchase; for the entire time of operation, the machine has never failed. It works automatically, press the button - and that's it. Loads almost half a kilogram of beans, convenient electronic control, 25 grind levels, easy to clean and a bowl large enough for ground coffee. They did it for the carob coffee maker and for the Turks, everything is just fine. For the device - an A plus.
Great coffee grinder! I got it not so long ago, while I like it. The attraction is that the start button does not need to be held for a long time, it is enough to set the desired degree of grind and press the button. Everything is on the machine, the grinding is uniform, the coffee at the outlet is cool, I don't see any flaws yet. Let's see how it will work next.
I bought my first coffee grinder from this manufacturer about 6 years ago. All this time, I worked with almost no problems. Although I didn’t use it that often. I only changed the knives 2 times. Now I decided to buy a new model. I wanted to buy the most powerful one, but it turns out a little expensive. Therefore, I settled on a cheaper option. Hope it doesn't let you down.
I am a big coffee lover and I try to drink only good varieties. And in order not to spoil quality grains, I use a good grinding machine. Bork is excellent for this purpose, it does everything efficiently and quickly.
Colleagues gave a Bork coffee grinder as a birthday present. Beautiful design, stylish and austere. Fits perfectly into the interior of the kitchen. There are no complaints about the grinding, it is suitable for any coffee maker, it works quietly. I am delighted with such a cool gift!
VIDEO The first mentions of coffee in Russia are found in documents from the middle of the 17th century, during the reign of Tsar Alexei Mikhailovich. Emperors Peter I and Catherine the Great were coffee fans. The quality of an invigorating drink is very much dependent on the grinding: fine dust will increase the bitterness, large particles will make the coffee watery. What are the types of coffee grinders, how to grind beans correctly? What are the malfunctions of coffee grinders, how to carry out a simple repair of a coffee grinder with your own hands?
The birth of the electric coffee grinder is marked in history on April 3, 1829. On this day, James Carrington received a patent for his electromechanical invention. Up to this point, coffee was ground manually, using a manual coffee grinder. Its device was a reduced copy of a mill, and coffee beans were ground by grinding them between two millstones. With the use of an electric motor, two designs of coffee grinders appeared.In one, all the same traditional millstones are used, and this type is called a millstone. In another, metal knives rotating at high speed took on the role of the grinder and therefore the coffee grinder is called rotary.
The millstone type of a coffee grinder consists of three sections. Whole grains are poured into one. In the second, they are ground and poured into the third section on their own in the form of a ready-to-use powder.
VIDEO
The rotary coffee grinder has one section, in which the loaded beans are ground by means of a crushing mechanism and poured out manually.
In addition, a modern coffee grinder is equipped with additional systems that allow more productive use of the machine's capabilities.
— Blocking of starting the engine when the cover is open.
Prevents spilling of grains when trying to turn on the motor with an open or loosely closed lid. As a rule, all grinders are equipped with this function. Blocking is especially relevant in rotary devices.
— Motor overheating protection.
Automatic shutdown of the motor in case of excessive heat. This function significantly extends the life of the unit.
— Pulse mode.
A very useful mode when crushing especially hard products. For example, when grinding dried rose hips or hawthorn berries before brewing. It consists in the fact that the operation of the engine alternates with short pauses, during which the speed of rotation of the working shaft decreases.
A timer in rotary coffee grinders regulates the grinding degree. The longer the grinding process takes, the finer the outgoing product becomes.
— Grinding "depth" regulator.
Usually used in grinders with burrs. Adjustment is carried out by decreasing or increasing the gap between the burrs. Numerous recipes for preparing a coffee drink are based precisely on different fractions of ground coffee beans.
So, for example, to make coffee in a Turk (cezve), you need the finest grinding "into dust". The espresso is slightly coarser for brewing, and the coarser grind is used for the French press. In total, experts have up to 25 degrees of coffee grinding.
Equipping a coffee grinder with an electric motor greatly facilitated the work of a housewife, since grinding coffee beans by hand is a rather tedious task.
The power of the grinder plays an important role in the processing of coffee beans. The more power, the higher the performance of the device. It usually ranges from 80 to 170 watts. On the housing, the power is indicated on the nameplate with the technical data of the electric motor. The label is glued or riveted on the bottom of the device.
True gourmets of the drink claim that when preparing coffee, the most important thing is its correct grinding. There is a whole science that describes all the nuances of this seemingly simple operation. Due to the fact that the popularity of coffee consumption has recently become huge, there are narrow professionals in this area of culinary. Sometimes their opinions differ. However, when it comes to grinding coffee beans, experts tend to believe that the correct grinding takes place either in a manual coffee grinder or in an electric coffee grinder equipped with a millstone. The rotary grinder grinds less evenly and the final product contains particles of different sizes. In addition, at high knife speeds, the coffee burns, which leads to a change in its taste.
The grinding time should not be long. As well as the time from grinding to brewing the drink. The longer the coffee is ground, the more essential oils evaporate. Therefore, the optimal grinding time is considered to be no more than 20 seconds.
Over time, the grinder began to be used not only for coffee. It can crush nuts, eggshells, cereals, salt, sugar and other bulk food products. For example, at home, using a coffee grinder, you can make powdered sugar from ordinary loose sugar.
To obtain powdered sugar, you need to load a certain amount of granulated sugar into the capacity of the coffee grinder and turn on the engine for a few minutes. To obtain a high-quality powder, you need to bring the consistency of the powder to a state of fine dust. A little vanillin or vanilla sugar is added for a fragrant smell.
In culinary practice, powder with an admixture of fragrant nutmeg is also used. To do this, first grind a well-dried nut, and then add sugar to it and grind everything together.
It is not recommended to grind foods with a persistent odor in the same grinder. So, for example, you should not crush pepper in it, the persistent smell of which can then be transferred to the coffee drink.
In a manual grinder, the grind size is adjusted using manual adjustment. Typically, the adjusting screw is located where the rotating millstone is attached. By screwing or releasing it, you can achieve such a size of the gap between the millstones, at which the particle size will be optimal. However, you cannot overdo it when reducing the gap. If you set it too small, the metal surfaces will rub against each other, creating small chips that will mix with the coffee and get into the food.
VIDEO
If a rotary coffee grinder with rotating knives is used, the time for complete grinding is determined by visual inspection. To do this, by switching off the grinder, the lid is opened and the degree of readiness is assessed. If the powder is not fine enough, the procedure is repeated. Many grinders of this type usually have a transparent plastic lid. This allows you to control the grinding process without removing the lid or turning off the engine.
If the coffee grinder works on the principle of grinding with millstones, then the degree of grinding is regulated using a special adjusting device. This mechanism allows you to increase or decrease the gap between the rotating millstones, and thus change the size of the powder at the exit. In practice, this is expressed in the rotation of the adjusting wheel located on the grinder housing. The adjustment algorithm is quite simple. Rotation of the wheel in one direction leads to an increase in the fraction of ground coffee. In the opposite direction - to decrease. In everyday life, everyone can, with a little experimentation, achieve the desired degree of grinding of the grains.
Like any electrical appliance, the coffee grinder can only be used in compliance with the rules and regulations of use.
In rotary coffee grinders, the main focus should be on regularly cleaning the working knife. It needs to be cleaned every time you grind coffee. This is done with a damp cloth or napkin. Remains of ground coffee must be carefully removed from the cutting edge of the knife, otherwise they can oxidize and become unusable over time. Naturally, the entire remaining cavity of the working container is subject to cleaning.
In the millstones, there is no access to the working surface, but it is advisable to change the millstones themselves after a certain period of time. It is considered that replacement should take place after grinding work of about 250 kg. coffee. Such a durability resource is incorporated in the design of the apparatus, and when it is depleted, the grinding quality decreases.
Do not wash the grinder by completely dipping it in water. Since in this case its electromechanical part may become unusable. It is permissible to wipe the case with a damp cloth.
During operation, you must adhere to the optimal operating time of the device. According to experts, the continuous operation of the motor is more than 1 minute. negatively affects its durability. If there is a need to continue working, you need to pause for 15–20 seconds. and only then turn on the device again.
From time to time, any technique malfunctions. This happens either due to wear of the mechanism, or with the occurrence of a particular emergency situation. The grinder is no exception in this regard.Despite the extreme simplicity of the device, problems occur in its operation. They can be conditionally divided into two categories.
The first includes malfunctions that change the quality of work. This is, first of all, insufficient grinding of the coffee beans. This happens with prolonged use of the device without current routine maintenance. So knives and millstones need to be updated from time to time. If this is not done in a timely manner, the degree of grinding will gradually, but inevitably, decrease.
In rotary coffee grinders, the crushing blade must be replaced. Sharpening it at home will not lead to anything good, since there is a high probability of disrupting the balance of the product. An unbalanced knife at high speeds will create vibration and the quality of chopping will not noticeably change. Since the cost of a replacement knife is quite democratic, replacing it will not cause financial stress. The replacement is made by rotating the knife in the same direction in which it works. In order to prevent it from turning with the drive shaft, the engine is jammed with a screwdriver. The old knife is removed, the new one is installed in its place.

The millstones are changed in the millstones. Millstones come in various shapes (plane-parallel and tapered) and are made from different materials (stainless steel or ceramic). In addition, various companies that produce coffee grinders use different types of attachments for millstones. All this complicates the general recommendations for their replacement, but most often this operation is described in detail in the operating manual of the device. Having studied them carefully, everyone will be able to make a replacement on their own at home.
After replacing the millstones, their adjustment to the fineness of grinding becomes relevant.
The second category is damage to the electromechanical part of the grinder.

Hello! I earnestly ask you to help the veteran with advice! My Bork CG700 coffee grinder has stopped working. After disassembly, it turned out that the engine was in good order, and the fault was on the electronic board, which I could not remove from the case. The round knob of the grind switch, which cannot be removed, is interfering. I am afraid to make a lot of effort, because I don’t know if the handle sits on the axle on friction or is fixed to the switch. Respectfully yours, Viktor Yakovlevich.
It is forbidden to write answers that do not bring any benefit to the questioner from the series: “bring it to the service”, “contact the ASC”, “unprofitable”, etc. Answers like these will be considered a rating cheat, the answers will be deleted, and the account will be blocked.
If you undertake to help people, answer fully. Explain why, if you recommend, for example, reflashing your phone, then write how to do it. If you write that repairs are unprofitable, explain why.
Modern household appliances are not durable. And if you still use the device not for its intended purpose, then the rate of its failure increases significantly. This can happen with a coffee grinder if sugar and other harder foods are ground instead of coffee beans. But, regardless of whether the device broke down due to improper operation or for other objective reasons, you should not rush to contact the service center. Most likely, it is quite possible to repair the coffee grinder with your own hands.
Today's electric coffee grinders are available in two types: millstones and percussion grinders. The lion's share space in the case the device is occupied by an electric motor - up to 80%. The rest of the area is dedicated to coffee beans. For instance, at millstones the grinder is divided into three sections. The first is filled with a portion of raw materials for processing. In the second, grinding takes place directly. And in the third, finished products are assembled.
V impact type designs installed knives. It is they who grind the grains into powder at a high rotation speed. Sometimes this mechanism is called rotary. And it only has one hopper that holds roasted coffee beans. Processing takes place in it. And the ground raw materials are simply poured into another container. In terms of its structure, such a coffee grinder is very similar to a blender.
Important! All devices are equipped with a motor lock when the lid is open and overheating protection. In many models, an additional pulse mode has been added, which with short engine stops helps when crushing harder products. For example, when you need to make powder from sugar.
Rotary coffee grinders often set a timer ... It is needed to regulate the degree of grinding. The longer the process, the smaller the product yield. In millstone structures, this role is played by grinding depth adjuster ... To do this, increase or decrease the gap between the millstones. Unequal grinding fractions are needed to prepare a drink according to different recipes.
Advice! To brew coffee in cezve, you need to grind the beans into dust. And for brewing espresso, a coarser grind is needed.
It is not difficult to disassemble the device if you know the diagram of the device. The design of all grinders is almost the same, but the assembly is different for different brands. And the famous Bosch company has two models with different disassembly methods.
It is easy to find people who still successfully use Soviet household appliances. Produced in a long-defunct country, coffee grinders are not inferior in productivity to their modern counterparts. They will open a list of instructions for the correct disassembly of such devices.
Made conscientiously back in Soviet times ZMM brand coffee grinder you have to disassemble, if not for repair, then at least for cleaning and maintenance work. The sequence of actions is as follows.
Free the knife. To do this, find a slot on the bottom of the case, insert a screwdriver into it and unscrew it counterclockwise.
Using a spanner wrench or pliers, unscrew the plastic nut by half a turn (left or right), which is located immediately under the knife.
Remove the plastic cup holder with the glass.
Remove the metal washer from the retaining axle.
To remove the plate, you must simultaneously press on it together with the blocker and turn it counterclockwise until it comes out of the grooves.
Bend back the retaining spring and release the switch.
Remove the dirt protection washer from the axle.
Move the ring at the bottom of the housing and unscrew the screws securing the electrical cable.
Take out the engine.
Important! When removing the knife, there is a risk of ripping off the slot. After this, further disassembly will be impossible. To prevent this from happening, you must first spray on it from a can of WD-40 and wait a few seconds. This will make it much easier to unscrew.

Completely similar sequence diagram when disassembling another Soviet model - ECMU 50. But modern electric coffee grinder "MIKMA »ECMU IP-30 from a Moscow manufacturer (a subsidiary version of the Soviet prototype), the algorithm is the same up to the fifth point inclusive. Then you need to do the following:
do not remove the bar, but carefully lift and move to the side;
before disconnecting the conductor, you need to push it out of the button body and remove it to the right;
take out the electric motor;
remove the oil seal from the engine shaft;
free the shields from rubber shock absorbers;
remove the spring from the groove inside the device to remove the button;
unscrew the two screws hidden under the rubber ring on the bottom to disconnect the power cord from the case.
Straume 3 is another coffee grinder made in Riga during Soviet times. And here's how she understands you can watch the video:

Probably the easiest disassembly method of all coffee grinder samples. Bosch mkm-6003 ... The algorithm of actions is as follows: to remove the knife, you just need to unscrew it clockwise, and you can pull out the motor by loosening the power cord and pulling the motor towards you. That's all.
With model Bosch mkm-6000 one person can no longer cope. Need outside help or access to a good vice. First, you need to fix the unit in the hands of an assistant or clamp it in clamps so that it is strictly in a horizontal position. Further, with a screwdriver or a probe, you need to pry the bottom in the area of \ u200b \ u200bthe attachment of the power cord. Then, having driven the first screwdriver to a depth of one centimeter, the second needs to grope for the latches and carefully separate them. In this case, you should hold the bottom so that the motor does not fall out, which it presses against. The apparent simplicity of the process should not be misleading, since the main difficulty lies precisely in the latches, the disconnection of which requires a lot of skill and patience.
VIDEO Basically, all coffee grinders are easy to disassemble. Usually it is enough to unscrew 2-3 screws from the bottom of the case. Sometimes you have to tinker with the latches. But there are also secrets, like a model Bork j700 : to get to the printed circuit board, you need to remove the grind switch knob, which is attached instead of the nut with a washer (it is this that needs to be unscrewed). The original opening is also characteristic of the coffee grinder Elmaz ... The nuance lies in the fact that you first need to turn the bottom with your palm, and then remove it from the hooks in the body.
Advice! Separately, we can say for the model Vitek 1540 ... It is not recommended to disassemble it at home. This can only be done by qualified service technicians.
The following will describe methods for repairing coffee grinders that do not require in-depth knowledge. Namely:
the device does not turn on;
knives spin unevenly;
malfunctions in the motor;
break in the power cord;
other typical simple breakdowns.
When the device shows no signs of life , then first of all you should look for a violation of contacts and wire breaks. If the inspection did not reveal a problem, then the reason lies in the electric motor, which can only be eliminated in the workshop, since special knowledge is needed.
Important! When the knives are spinning with sticking, then there is an obvious fault of the burned-out motor winding. At home, for a person ignorant of such matters, rewinding the winding is simply not realistic.
But if the motor works with effort and there is a burning smell , you can try to do without a specialist. Most likely this is due to contamination of bearings or sleeve bushings. To fix the problem, you need to free the shaft and wipe it with alcohol. In case of obvious corrosion, you can treat it with WD-40 or neatly with a sandpaper. For interruptions in engine operation, brushes may be responsible. In this case, cleaning or their complete replacement is required. You can wipe the entire manifold with alcohol if dirt has accumulated on it.
Break points and breaks at the power cord immediately catch the eye. If it is not possible to replace it with a new one, then the wires at the break point should be stripped, re-soldered and re-insulated. There are also cases when, due to contamination of the push mechanism, a blocking failure occurs. This issue can be easily solved by disassembling and cleaning the non-working unit.
In order for the coffee grinder to work as long as possible, you need to follow simple rules of operation and prevention. .
Do not leave ground coffee in the device for a long time.After every grinding need to wipe the inner bowl and knives with a damp cloth.
Do not immerse the device in water when washing , it is better to limit yourself to a wet rubdown.Machines with plastic enclosures can overheat and fail after long continuous operation. Such failures are frequent with the brands Moulinex and Saturn. If take short breaks in grinding every 20 seconds , the service life of the grinder can be increased.
Need to try to avoid chopping other foods ... There is a blender for this.
Should timely change dull knives and millstones ... The latter must be replaced after grinding 300 kg of grains, and the former much more often.
Fulfilling simple rules for the care and operation of the device, regularly carrying out preventive work and timely performing minor repairs, you can extend the life of your favorite coffee grinder, which will delight you with many years of faithful service.

Modern coffee grinders are without a doubt reliable and efficient, but they are designed for specific tasks. For example, the grinder may need repairs if sugar is ground in it instead of coffee beans. Other models, especially those made by Bork and Bosch, suffer from moisture penetration into the motor shaft area. But in any case, if the engine has not burned out, you can fix the device yourself.
Most coffee grinders have a fairly transparent disassembly algorithm. There are two types of devices:
knife coffee grinders;
millstone mills.
The latter have a separate algorithm for disassembling the grinding mechanism. The answer to the question of how to completely disassemble a burr-type coffee grinder depends on from a specific model devices. The general scheme is the same. The conical mill knives are attached to the drive shaft with three to four bolts. Unscrewing them is easy. However, when reassembling, care must be taken to ensure that the heads are fully seated in the seats. If you assemble the grinder without tightening the bolts, you can burn the grinder, or you can constantly find fine metal dust in the grind due to the protruding heads of the fasteners protruding into the zone of movement of the grinding mechanism.
Coffee grinder cases are easy to disassemble. It is required to unscrew a couple of self-tapping screws, which are often located on the lower plane, the bottom of the car. Access to them can be either open or protected by the device's legs.
A separate group of coffee grinders keeps on latches ... For example, the Bosch MKM 6000 models, the Soviet ZMM apparatus, the EKMU 50 and EKMZ 125 millstones. Here, the lower part of the case is removed using thin probes or screwdrivers with which the latches are bent.
VIDEO Pulling out the motor to inspect the condition of the bearings and shaft requires dismantle knives ... They are filmed in different ways. The most common type of connection is threaded. In this case, the principle of self-tightening is used. If the knife moves clockwise, then a left-hand thread is cut at the connection. If counterclockwise - right. To dismantle the knife, you need to place the slot of the screwdriver in the corresponding slot in the shaft, and then turn the knife block clockwise or counterclockwise, depending on the thread.
Care must be taken when dismantling the knife. The indentation on the shaft is shallow, the metal is soft, so the screwdriver must be placed tightly, pressed down and when unscrewing the knife, apply force gradually.
VIDEO
Over time, the attachment area becomes clogged with the remnants of grindings, gets caught in oxides. Therefore, it is recommended to apply grease WD-40 to remove dirt and easily unscrew the knife block. In the case when the clamping nut has a tapered thread and is made of bronze, you can slightly heat the connection area using a soldering iron.
Further actions depend from the coffee grinder model ... It is necessary to disassemble the device carefully, following the limiters, removing the structural elements from the grooves. More often than not, after removing the knife block, you need to do very little:
Unscrew the plastic fixing nut that secures the grinding bowl. The felt anti-dust pad attached to the fixing nut must not be lost.
Remove the steel axle washer.
Remove the bollard plate by gently pushing it down and out of the restrictive grooves in the body.
VIDEO
Dismantling of most models of coffee grinders (for example, Saeco GROUP 700, Bosch MKM 6000) ends with the removal of the anti-pollution washers and the dismantling of the power cable, switch. In the course of detailed disassembly, it can be established that, for example, a washer has burst or a felt gasket is completely unusable (greasy, compacted).
Replacing a destroyed element is not difficult. To do this, you should know coffee grinder detail , the Internet has data on most common devices. After that, you can go to the market, to a specialized store or service center, having in your hands the precisely designated name and number of the desired part.
Saeco Grinder Detail Example
To repair the engine or determine its performance, you need a multimeter and knowledge of where to measure the resistance of the windings. Therefore, we will only touch on the relative minor problems that can be eliminated even with minimal tool handling skills.
A broken power cable is visible to the naked eye. But if the bend is close to the case, you can detect a breakdown simply by moving the wire. If the device begins to show signs of life, it means that you will have to change the cable.
Lock failure occurs due to clogged pressure mechanism (is in line with the cover groove) or the inner plate is not pressed. Checking the blockage is simple - press on the protruding plastic element with a thin screwdriver. If, at a certain position, the coffee grinder comes to life, you need to disassemble it and remove the dirt.
There may be several reasons: from a cable break inside (to eliminate such a problem, you will need skills in working with a soldering iron) to engine failure. In this case, verification will require special knowledge. In this case, repairs are economically ineffective, rewinding or buying a new engine is required, it is often easier and cheaper to buy a new grinder.
One of the reasons is partial failure of the motor, burnout of one of the windings. Repairs can be a problem. Diagnostics, rewinding or expensive replacement will be required.
The most common cause is contamination and oxidation of bearings or sleeve bushings. This problem is very often observed in Bosch 6000 series coffee grinders. To eliminate contamination, you need to carefully disassemble the device, check the ease of sliding of all blocks, lubricate the bearings. The Bosch 6000 models do the following:
the sliding sleeve is removed from the shaft (upper part);
the shaft is treated with alcohol;
if there are obvious signs of corrosion, it is removed using special tools or WD 40.
The shaft can be machined sandpaper-zero , you need to act carefully. The procedure shown in the following video is not a commonly used one. With diligence and constant repetition of this kind of maintenance, it is possible to change the gap in the sliding sleeve, which will lead to all kinds of problems.
VIDEO
The coffee grinder can be repaired periodically. Maintenance procedures include lubrication and decontamination. To avoid accidents, do not operate the grinder in modes not recommended by the manufacturer. For example, grind sugar into powder, grind herbal spices, process large masses of grinding. Each technique has its own operating rules and if you do not violate them, the device will work for a long time and trouble-free.
