Details: do-it-yourself bork coffee grinder from a real master for the site my.housecope.com.
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.
They are attracted by the high quality of branded models: a large selection of grinding degrees, the presence of a millstone mechanism and a display indicating operating parameters, a convenient design and good capacity. Nevertheless, experts and consumers do not see any good reason for an overly high price for these kitchen appliances.

Bork J800
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!

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, a multimeter and knowledge of where to measure the resistance of the windings are needed. 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 by simply 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 the 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, resulting in 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.

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 great 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, the blocking fails. 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.

Buying already ground solid products (coffee, nuts, cereals) is quick and convenient, but no one can guarantee that the product is 100% natural. To be sure of the quality of the ground products, you can buy a coffee grinder and grind coffee beans, spices, etc. with your own hands.
The most ridiculous and unpleasant situations can be a reason for disassembling a coffee grinder.
On multiple thematic forums, consumers indicate such problems with the device:
Broken part (for example, a switch, a loose cord, reduced speed and a complete stop of the electric motor).
The knife is dull and needs to be replaced.
Contact of the grinded product with electrical components.
Curiosity, a desire to know what parts a coffee grinder consists of.
Each device model is disassembled differently. In order not to break the grinder, you need to follow the instructions from the manufacturer or the advice on the seller's website.
German Bosch technology is known for high quality products, durability and versatility of devices. In the assortment of coffee grinders, manufacturers often choose two photo models - Bosch mkm-6003 and Bosch MKM-6000. Both partings are characterized by high power, but the disassembly of each model is different.
To disassemble the Bosch mkm-6003 coffee grinder, you must first remove the impeller - in a clockwise direction. Then loosen the wire and pull the motor towards you. If there is debris on it, you can clean it off with a soft brush. It is better not to touch the motor of the Bosch mkm-6003 coffee grinder itself, and in case of a malfunction, contact the master. The detailed performance of each disassembly operation can be viewed on the video on the Internet.
Disassembling the second model is much more difficult, you cannot do it with your hands alone. The best assistant for opening the Bosch MKM-6000 coffee grinder will be two flat-slot screwdrivers (no more than 1.5 mm thick, the distance from the slot is 8 mm, the width is 4-6 mm).
Work process (designed for two people):
Take the grinder with one pair of hands, set it horizontally and hold it firmly.
With the second pair of hands, take a screwdriver and, at a distance of about 8 mm from the hole for the electric cable, drive it into the gap between the lateral cylindrical part and the bottom to a depth of 8 mm.
The first screwdriver must be inserted at an acute angle, heading up from the bottom of the device, with the second screwdriver, help the first to make a gap.
Floor increase in the pressure angle of a screwdriver inserted into the gap; the coffee grinder has been opened.
Before you disassemble the Bosch coffee grinder, you should get a camera to create a photo of step-by-step work. This will help to quickly and correctly assemble the device.
Soviet manufacturers of household appliances for the kitchen tried to make it as functional and convenient as possible. Even after many years of operation, the ZMM coffee grinder performs its functions perfectly, but if problems arise, the device can be disassembled. This must be done in the following sequence:
Remove the knife with a screwdriver - insert it into the slot on the bottom of the device and unscrew the part with a smooth counterclockwise motion.
Unscrew the plastic nut by turning the pliers counterclockwise 90 degrees.
Remove the plastic glass and cup holder.
With a gentle movement, the metal washer is removed from the axis holding it.
By simultaneously pressing the fixing plate and the blocker, turn the parts also counterclockwise and remove the plate (after it comes out of the grooves).
Next, you need to remove the power button after the fixing spring is bent.
Remove the dirt protection washer from the axle.
- Release the wire after carrying out such manipulations: bend the ring in the lower part of the ZMM coffee grinder, unscrew the two screws securing the electric wire.
Remove the appliance motor.
The technology of disassembling the ZMM coffee grinder is somewhat reminiscent of opening the Mikma Ekma IP-30. Some models of coffee grinders generally do not recommend disassembling at home. One of these models is Vitek 1540. The only thing that can be done with this device is to disconnect it from the power supply and thoroughly clean the inner surface and knives. The manufacturer recommends doing everything else in a service center or in the office of a qualified technician.
The majority of uninformed buyers cannot disassemble the IP-30 coffee grinder from a Moscow company the first time.
You can correctly disassemble the Ekma coffee grinder in the following sequence:
Remove the plastic cover.
Hold the impact mechanism divider with one hand, and take a screwdriver with the other hand and unscrew the screw at the bottom of the grinder with smooth movements.
Remove the divider.
Using pliers, turn the plastic holder (from right to left and vice versa) located inside the metal bowl.
Remove the holder from the bowl.
Remove the protective sleeve and bowl from the device body.
Turn the metal bar from right to left and disconnect it from the grooves in the grinder body.
Pull out the contact from the base of the power button, take it gently to the side, remove the electric motor from the case.
Remove the oil seal from the engine shaft, from its shields - rubber shock absorbers.
- Inside the housing, remove the spring that controls the operation of the closing button and remove the button.
Unfasten the power cord after unscrewing the bracket fixing screws.
The technology for disassembling the Mikma Ekmu IP-30 coffee grinder is rather complicated, so at home it is better to do this according to the video example.

Appliance manufacturers use a wide variety of technologies. Most of the devices are characterized by high strength and tight fastening of parts. For example, it is precisely because of the manufacturing technology that it is difficult to disassemble the Bosch coffee grinder (model Bosch MKM-6000), and its analogue, the Belarusian model Vitek 1540, can be opened in a few minutes.
What is a good and high-quality coffee machine for? Of course, for aromatic hot coffee in the morning. The brewing process of this wonderful drink is almost completely automated and requires minimal human intervention. The filling of the device implies the presence of many mechanical parts, electronic circuits, as well as a miniature hydraulic system. However, everything soon fails and these necessary devices are no exception. In the event of a breakdown of coffee machines, there are only two options: take it to the service or repair the coffee machine yourself.
Water supply interrupted. There is a blockage in the pipeline of the mechanism;
The coffee has acquired an unusual smell or taste. In this case, it is not always necessary to fix something with your own hands. Perhaps you just need to change the coffee tablets, and there is a very wide selection of them: Dolce Gusto - Dolce Gusto, Nestlé, Jacobs, etc. Alternatively, the filter of the coffee machine may be clogged. Cheap plastic can be another factor affecting the taste and smell of coffee. During operation, some parts of the machine heat up to 130 degrees, which can cause the plastic to melt;
Cold coffee.Most likely, your heating element has stopped working;
The espresso machine is not working. Many factors can affect this: the motor is broken, the pump does not work, the power cable is broken;
Water dosage exceeded (most often found in capsule coffee machines). Most likely, the breakdown lies in the engine or in the timer circuit.
The brewing time setting circuit does not work or the dosage into the cup is incorrectly adjusted. Of course, you need to focus on the model of the device and its brand, but a common reason is the improper operation of the engine control circuit, or one of its compartments.
If you are not sure that the repair of the coffee machine is within your power, then it is better to refer it to specialists. If the device is under warranty, then it is not worth disassembling it at all, it will instantly lose the warranty.
To repair the coffee machine, first you need to disassemble it. And how to do it correctly, step by step is described below.
It is necessary to find the back wall of the device, or rather the set screws. Unscrew with a screwdriver, pliers or whatever is at hand and is ideal for such work, set aside. It is worth noting that there may be several options for screws. They can be hidden, cruciform, or with a convex head;
The screws are removed, it is logical that the cover should be easily removed. However, if it cannot be removed, then there are hidden locks in the case. Most often these are ordinary plastic latches and they are located at the bottom of the back cover. From the outside, such a lock can be easily opened with a knife or a small screwdriver;
Finally, access to the "insides" of the machine has been obtained, it's time to start repairing it.
And so let's go in order. There is a blockage in the water supply pipe. In such coffee machines as: Delongee, Bork - Bork, Ariete - Ariete and others, cleaning is done using a long and thin rubber hose. It must be run along the duct and thereby break through the blockage. However, it will be much more effective to use special brushes on a flexible leg.
It is a little more difficult to clean the filter with your own hands. With frequent use of the coffee machine, the filter accumulates: scale, coffee residues, salt plugs, etc. Cleaning must be approached carefully, but the most important thing is to do it according to the instructions, otherwise you can violate the integrity of the part. In the process, it is allowed to use a soft swab sprinkled with alcohol. Rinse the filter thoroughly after cleaning.

If you are unable to solve the problem yourself, contact a Saeco espresso machine repair center.
The coffee machines of the firms Mulinex, Krups, Roventa, Saeko have another problem - water leaks. In them, the valve regulating the water supply is located practically in the filter. If the coffee does not stop pouring, most likely a worn valve is to blame, which leads to this phenomenon.
The valve cannot be repaired; in this case, only replacement with another new part is available. To understand whether the valve has broken, it is enough to pour coffee out of the machine, disassemble, rinse and inspect well for possible breakdown.
Initially, it is worth checking if everything is in order with the power supply. See if the cable is broken, check the grounding.
It also happens that household coffee machines produced in China simply lose contacts (they go away). Such cases were encountered with more famous brands: zauber, melitta, trevi. It is enough to check all the wire connections with the control circuit.
A common case for Senseo¸Siemens, Ufesa machines, they have low-quality thermostats built into them. To diagnose it, you need to remove one wire from its end and "ring" the contacts with a tester. If all is well, then the chain will be closed.
The heating element may also fail. Diagnostics is carried out in the same way as a thermostat. Replacing it with a new one is difficult, it will be easier to try to repair or buy a new coffee machine.
Very often, on the shelves next to the coffee machine, all the necessary accessories are sold that you will certainly need for the correct operation of the device. And for cleaning technical parts, it is definitely advised to buy special flexible brushes.
The principle of operation and repair of capsule coffee machines is slightly different from drip coffee machines. A small container of coffee powder is attached to the inside of the machine, the piercing mechanism is manually clamped. After use, the capsule is disposed of. Inside such devices, most often there are no temperature sensors, but there is an ordinary pump that runs on a timer. The water flow rate has been calculated in advance. If the water supply is carried out with the wrong dosage, then the time supply circuit may have broken.
Repair of coffee makers often does not depend on the brand or model; in general, they differ only in nuances. This can be the shape, as well as the location of parts, size, different types of sensors. The very principle of operation of the coffee machine does not change.
