How to disassemble a krups coffee machine

Tips for repairing coffee machines with your own hands.

Why do you need an excellent and high-quality coffee machine? Of course, for fragrant hot coffee in the morning. The process of brewing this wonderful drink is almost 100% automated and requires little human intervention. The inside of the device involves the presence of a huge number of mechanical parts, electrical circuits, and also a small hydraulic system. But everything soon breaks down and these necessary devices are no exception. When coffee machines break down, there are only two options left: take it to a service center or repair the coffee machine yourself.

The main difficulties of coffee machines and coffee makers

The water supply is interrupted. There is a blockage in the mechanism pipeline,
The coffee has acquired an uncharacteristic smell or taste. In this case, it is not always necessary to repair something yourself. Maybe you just need to change the coffee pills, and there is a very wide choice: Dolce Gusto, Nestlé, Jacobs, etc. Another option could be that the coffee machine filter is clogged. Another factor affecting the taste and smell of coffee may be cheap plastic. During operation, some parts of the machine heat up to 130 degrees, which can cause the plastic to melt,
Cool coffee. Most likely, your heating element has stopped working,
The carob coffee maker does not work. This can be caused by a huge number of reasons: the motor is broken, the pump is not working, the power cable is broken,
The dose of water has been exceeded (in most cases it occurs with capsule coffee machines). Most likely, the breakdown lies in the engine or in the timer operation circuit.
The cooking time option circuit does not work or the dose per cup is incorrectly adjusted. Of course, you need to focus on the model of the device and its brand, but a common prerequisite is the incorrect operation of the motor control circuit, or one of its compartments.

If you are not convinced that you can repair a coffee machine, then it is better to take it to a specialist. If the device is under warranty, then there is no point in disassembling it at all; it will instantly void the warranty.

How to repair a coffee machine if it does not see coffee?

The coffee machine does not see the coffee
. It happens that a Saeco or other coffee machine does not work because it ignores the coffee. At the same time, there is definitely grain in it. Causes:

Failed control unit.
Engine failure.
Coffee maker malfunction.

A good diagnosis is necessary. If you see that everything inside the machine is covered in coffee dust, then the problem is with the coffee maker. And you will have to replace the engine or buy a new coffee machine.

Also, the coffee machine may malfunction due to a blockage in the brewer or grain that has a different grind. Then you simply won't be able to brew coffee. And you need to set a coarser grind on the control panel or clean the brewing device.

How to disassemble a coffee machine?

To repair a coffee machine, you first need to disassemble it. How to do this correctly is described step by step below.

You need to find the back wall of the device, or more precisely the installation screws. Unscrew it with a screwdriver, pliers or whatever is at hand and is perfectly suitable for such work, set aside. It is worth seeing that there may be several screw options. They can be hidden, cross-shaped or with a convex head,
With the screws removed, it makes sense that the cover should be easy to remove. But if you can’t remove it, it means there are hidden locks in the case. In most cases, these are ordinary plastic latches and they are located at the bottom of the back cover. From the outside, such a lock can simply be opened with a knife or a small screwdriver,
Finally got access to the “insides” of the machine, it’s time to start repairs.

And so let's go in order. There is a blockage in the water supply pipe. For coffee machines such as DeLongy, Bork, Ariete and others, cleaning is done using a long and narrow rubber hose. It needs to be run along the duct and thereby break through the blockage. But it will be even more effective to use special brushes with a flexible stem.

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. You need to approach cleaning carefully, but the most important thing is to do it according to the instructions, otherwise you can damage the integrity of the part. During the process, it is possible to insert a soft swab sprinkled with alcohol. After cleaning, thoroughly wash the filter.

If you were unable to solve the problem without the help of others, contact the Saeco coffee machine repair service center.

Coffee machines from the companies Mulinex, Krups, Roventa, Saeko have another problem - water leaks. Their valve regulating the water supply is actually located in the filter. If the coffee does not stop pouring, it is most likely due to a worn valve, which leads to this phenomenon.

The valve cannot be repaired; in this case, only replacement with another new part is available. To determine whether the valve is broken, simply pour the coffee out of the machine, disassemble it, wash it, and take a good look at the possible breakdown.

Complete refusal of the coffee machine to work

The reasons for the complete failure of equipment to work are unpredictable. Of course, you can systematize the sources of malfunctions by identifying a dozen main problems. However, any specialist will say that the root of evil lies in improper operation . These are lack of care, pouring hard water, low-quality grain and incorrect grinding. I will give the most common reasons leading to the fact that the functioning of the device stops.

Ubiquitous scale

The device may refuse to operate if the user does not periodically decalcify.

As a result, we can come to the following:

scale on the boiler;
scale on the water tank;
scale of the infuser.

Solution: cleaning. This process must be carried out competently, with the participation of professional means. Each brand recommends using a specific powder. But the principle of application is generally the same. The product is dissolved in liquid and poured into a water tank. The coffee machine is heating up. The steam valve opens and the flow is turned on. All the solution must pass through the boiler and tube. The device is turned on and left for half an hour. Next, the tank is washed and clean water is pumped through the system. It is better to drain the first portion of espresso.

Problems with the coffee grinder

The absence of coffee in the cup may indicate that the mill is broken. When the unit refuses to work, the machine stops brewing coffee.

The reasons for this are:

grain has been poured into the ground coffee compartment;
using low-quality grain - this can lead to melting of the coffee grinder parts;
hit by a foreign object - any pebble can block the millstones;
Water entered the unit causing electrical problems.

Solution : make sure there are no foreign objects in the module. If they are present, they are removed. If the millstones are damaged, they are replaced with new ones. The electrics will be reprogrammed. The last two steps are carried out at the service center.

A couple more important little things

A lot of serious breakdowns occur due to self-repair, which leads to an increase in problems. If the coffee machine was operated at low temperatures, the hydraulic adapter may be damaged by frost . There are options with regular use of hard water, which causes leaks in the thermoblock. A lot of problems arise from not replacing the filter, as I already mentioned.

If the coffee machine does not prepare drinks and does not respond to commands, the red indicator is on or flashing on the display , the source of the problem may be the following:

an overfilled waste pulp compartment - it should be simply cleaned;
lack of water in the tank - check for leaks. Add liquid;
sugar or ground coffee is poured into the bean compartment - I also talked about this.

All these reasons cause the device to block. If eliminating them does not lead to normal operation, a full diagnosis is required at a service center.

Control system failure

Electronic module failures are most common when coffee equipment refuses to work. The basis of this thing is a printed circuit board on which control elements for each component of the coffee machine are located. In the event of a breakdown, most often it is enough to carry out repairs, but sometimes a complete replacement is required.

If such a problem occurs, the device begins to flash all indicators and does not respond to switching on. The display may show strange characters. The equipment incorrectly performs or does not perform the required commands at all.

When restoring the system, proceed as follows:

replacement of connectors;
resoldering burnt parts on the board;
installation of new parts;
restoration of burnt paths;
System firmware is essentially a software replacement.

Breakdowns can occur for several reasons. The main one is a short circuit . This can cause overheating of temperature sensors, leaks, damage to the control unit, and a short circuit can also short-circuit the boiler. The source of the problem is high air humidity, water getting into the coffee machine, and voltage surges. Not all models are equipped with a transformer that prevents malfunctions, which, by the way, should be taken into account when choosing. The second point is unstable network voltage.

Solving the problem: in any case, the device must undergo diagnostics to identify the true cause of the problem. You can, of course, ring the system yourself, but without proper experience in repairing it, this will not give anything. Let's go to the service. I recommend that all activities be carried out in an official center or with a very good specialist, otherwise instead of a coffee machine you will receive its corpse, because the problem is serious.

The coffee maker doesn't turn on

First, you should check if everything is ok with your food. See if the cable is broken, check the grounding.
It also happens that household coffee machines produced in the Middle Kingdom simply lose contacts (they come off). Such cases also occurred with more famous brands: zauber, melitta, trevi. It is enough to check all the wire connections to the control circuit.
A common case with Senseo machines? Siemens, Ufesa, they have bad thermostats integrated into them. To diagnose it, you need to remove one wire from its end and “ring” the contacts with a tester. If everything is fine, then the circuit will be closed.
The heating element may also fail. Diagnostics is performed similarly to a thermostat. It is difficult to replace it with a new one; it will be easier to try to repair it or buy a new coffee machine.
Very often, on the shelves next to the coffee machine, all the necessary devices are sold that will definitely come in handy for you to properly operate the device. And for cleaning parts, technicians definitely recommend using special flexible brushes.

Lack of power

If your coffee machine does not work, then you can proceed by analogy with the instructions for repairing an iron. Breakdowns of coffee machines can be closely related to them. If the cord of the coffee machine is working, then you should check that the door is closed. Many modern models have a function that prevents the coffee machine from working when the door is open.

If it was not possible to visually identify the causes of the breakdown, then you should ring all areas of the device with a multimeter. It is better to take a coffee machine that has broken down to a service center.

Capsule coffee makers: operating principle

The operating principle and repair of capsule coffee machines differs slightly from drip coffee machines. A small container with coffee powder is attached inside the machine, and the piercing mechanism is clamped manually. After use, the capsule is disposed of. In most cases, there are no temperature sensors inside such devices, but an ordinary pump that operates on a timer. The water supply speed is pre-calculated. If water is supplied with the wrong dose, the timing of the supply may be broken.

Repair of coffee makers often does not depend on the brand or model; in general, they differ only in aspects. This could be the shape, placement of parts, size, different types of sensors. The mechanism of operation of the coffee machine itself does not change.

Any professional inspection for damage always starts with the cord. There is no difference between repairing capsule or drip coffee machines. Then the power board (if there is one) is checked; it is worth seeing that the coffee machine has a lot of filters, diode bridges, and also transistors. All this needs to be looked at for burnout. This is the only way to recognize the real reason why the equipment is not working properly.

We repair coffee machines ourselves.

An automatic coffee brewing machine is practically a godsend for lovers of a strong, fragrant drink. There are malfunctions in the operation of these modern devices, but a huge number of problems can be neutralized. Self-repair abilities depend on the brand and design of a particular model, but some problems are typical for all types of devices.

Technical indicators of the coffee maker that affect the taste

The material of the horn body is of particular importance. If the part is made of steel, then when boiling water gets into it, the coffee tablet warms up well. Consequently, the grains release all the aromatic substances. In a plastic case, the drink turns out watery due to insufficient heating.

The boiler also creates pressure, only in this case steam for frothing milk. If the pressure in the coffee machine boiler rises, a safety valve opens and releases it. The temperature of the water in the coffee machine boiler depends on the amount of coolant inside.

In professional models it reaches 120 degrees. The container is usually filled to 70% so that excess pressure does not damage the assembly. The liquid in the boiler is not used to brew coffee - it serves as a heat source to heat the water that will be used to make espresso.

The amount of liquid in the boiler is an important indicator for the stable operation of the coffee maker. The larger it is, the better it holds the temperature and the better the brewing liquid heats up.

Dispensing tubes, of which there may be several depending on the performance of the unit, are the nodes through which boiling water flows to the holder. The more dispensing units, the more portions you can prepare at the same time. The pressure in these units corresponds to the required 9 bar.

Why is steam needed in a coffee machine - to supply it to an automatic cappuccino maker or a steam wand for manually frothing milk. The temperature of the steam in a coffee machine is usually the same as the temperature of water, so when using the wand you need to be careful not to direct the stream onto areas of the body.

Adjusting the pressure in the coffee machine

A sensor installed inside the unit prevents overheating of the unit if the equipment operates in continuous mode. When you turn on the machine, you can determine from its indicators that the unit is ready for operation.

In automatic models, the sensor can alert users to problems by displaying an error message. In manual and semi-automatic coffee makers, you need to independently monitor the sensor indicators.

There are 2 pressure gauges in the coffee machine - for the boiler and pump. After using steam to froth milk, the pressure in the boiler may drop below the permissible level. Monitoring the arrow readings, you need to wait until the machine restores functionality, that is, it heats the water to the desired temperature and the steam creates the required pressure.

The pump pressure gauge shows the pressure in the espresso brew group. In the operating mode of a good coffee maker it is 8 - 9 bar. When the equipment is disabled – 0.

Separately about the most common brands on the market

All models of coffee machines are designed approximately identically. And repairing some coffee machines is easy to do with your own hands: they simply disassemble, you can clean, lubricate, inspect virtually everything, and then carefully reassemble them. But brands have their own characteristics:

Repairing Saeco coffee machines is comfortable and straightforward. Most of the models are disassembled identically, allowing access to all nodes.
Delonghi coffee machines are practically crammed with electronics, sensors, and control systems. Do-it-yourself repairs involve only fixing common problems. To eliminate severe problems, you should contact a service center.
Despite all their perfection, Krups devices are not safe. The heating elements are powered by a voltage of 220 Volts, so an unqualified owner, trying to repair the coffee machine, can receive a severe electric shock.

Schematic diagram of a coffee machine

Service of any coffee machine should be carried out one by one, first identifying the simple causes of the malfunction, and then moving on to more complex ones. Separately, it should be noted that some DeLonghi models can only be disassembled if you have special knowledge about the order of the process and the location of control systems.

De-energizing (pulling the device plug from the socket) is imperative to avoid severe injury or irreversible damage to device components.

The coffee machine is leaking

If your Delonghi coffee machine has become faulty because it is leaking where the horn and body meet, then it is not a big deal. And you can even fix it yourself.

Most likely, the leak occurred due to a clogged O-ring, which is located in the place where the nose enters the body of the machine. The blockage is fat, cake, grain, and so on. You need to disassemble the horn, remove the blockage and put the horn back together.

If the cause of the leak is that the seal is cracked or torn, you should buy a new one. It is important that the ring matches the characteristics of your coffee machine. If these requirements are not met, the rubber may melt from high temperatures or may not be as elastic as it should be.

When troubleshooting such a malfunction of the coffee machine and doing the repair yourself, check the filter of the horn. It should be clean, without coffee.

By analogy, you can fix a leak in a coffee machine from any other manufacturer. Change the other seal as well. The main thing is not to be afraid and replace it in time, before water begins to flow through the wiring or floods the control unit. If the machine stops pumping water, the piston above the teapot is probably damaged. You can also inspect and repair it yourself.

How to disassemble

Part of the answer to the question of how to disassemble a coffee machine looks like this: you should definitely stock up on a screwdriver with a long narrow slot, various bit attachments, and, if you have them, capes for unscrewing hexagons; you will also need thin pliers. In general, the process looks like this:

The rear wall is freed from the mounting screws. They can be very different - with a cross, a hex key, an asterisk, recessed, with a semicircular or flat head.
If you cannot release the back panel, it is worth examining the structure for the presence of latches. They are bent with a screwdriver with a long slot.
After freeing, the walls can be further disassembled; the process depends on the specific model of the product.

Some coffee machines provide access to most components after removing the back panel. Others will have to be examined more thoroughly. For example, for Saeko machines the complete process looks like this:

First, the front panel opens and the waste containers and coffee supply unit are pulled out.
The mug stand is dismantled, it moves forward together with the pallet.
The water container is removed from the rear; after removal, access to the lid of the bean compartment is revealed.
To dismantle the coffee storage compartment, you need to unscrew all the fastening screws and carefully remove it.
Under the container you need to remove another fastening screw.
Dismantling takes place from the front panel; there are a couple more fastening parts, accessible from below.
Behind the coffee bean compartment there is a final, deeply recessed mounting screw.
When removing the top panel of the coffee machine, you must disconnect the water supply hose.
Dismantling ends with removing the front door.

The main components of the Saeko coffee machine

After such disassembly, you can get to all components of the device. This will make it possible to inspect, clean and lubricate the mill mechanism, and check the presence of voltage at the main points of the electronic circuit of the Saeco coffee machine.

It is impossible to turn on the Saeco coffee maker

Models from the manufacturer Saeco are famous for their reliability. But anything can happen, and if the Saeco coffee machine does not turn on, you urgently need to “inspect” the design. There are three most common reasons that can incapacitate Saeko.

The power cord is frayed or broken. Or the plug is broken. It's worth checking the outlet too, just in case. Turn on other equipment. If it doesn't work either, it's a problem with the outlet. Examine the cord for mechanical damage. If present, replace it.
Often, Saeko coffee makers do not close the front door completely. There is no need to fix anything here. Open and close the door again as required.
Voltage surges. If it rains and thunderstorms, the voltage usually “jumps”, the fuse fails and the Saeko coffee machine does not turn on. In this case, the fuse should be changed. The part for Saeco can be purchased at hardware stores. If replacing does not fix the problem, check the motherboard. Perhaps a power surge ruined it. Here it is better to turn to a pro.

Common problems and solutions

There is no point in being tied to certain models of coffee machines. Each brand and model has its own characteristics, and repairing a specific coffee machine may have unique steps. For example, Gaggia Syncrony Logic machines use strictly roasted coffee beans, and a number of problems are associated with their lack of quality. Delonghi repairs in most cases are due to the use of unfiltered water and the lack of repeated decalcification procedures. From time to time, Krups capsules get stuck tightly in the supply path. Therefore, it is worth considering typical faults common to all coffee machines.

The car won't start

First, you should check the condition of the power cord, look for fraying, the presence of areas of sharp bending, or breaks. If damage or suspicion of its presence is discovered, it is worth changing the power cable.

Water is leaking in the horn area

Due to calcination, the O-ring no longer provides a tight seal. It is worth unscrewing the horn and washing the rubber part with special means to remove calcium deposits. If the ring has lost its elasticity or cracks, it needs to be replaced.

The device does not start

Errors on the screen and incomprehensible behavior during initial startup can be caused by clogged contact groups. If the car is equipped with a push-button remote control, you should try to carefully remove the decorative panel with a narrow screwdriver and check the condition, clean it with alcohol, and clean it if the plates are open to access.

In cases where the machine is controlled by a touch panel, you should contact a service center; difficulties may arise both in the control unit and in the multilayer contact group itself.

The reason that the device does not start and displays an error may be that one of the sensors is dirty. If a certain model of machine allows complete disassembly and access for cleaning, it is worth doing this; decalcification using special means will also not hurt.

Coffee is not brewed properly

A whole group of circumstances (decreased water flow, strange sounds, hissing, dose violation) is associated with the accumulation of contaminants and calcification. The first step is to run the water through the cappuccino maker. This eliminates air pockets. If this does not help, it is recommended to carry out decalcification with the following cleaning of the mesh with a stiff brush, the tubes with a needle, removing all blockages, coffee residues and grease. But the reason may also be the failure of the pump - then specialist intervention will be needed, it is worth contacting the service for a replacement.

No coffee grind

The coffee machine is disassembled, all clogs in the mill are removed using a vacuum cleaner and a brush, after which the device is assembled and set to the highest grinding dose mode. To control and completely remove residual contaminants, it is worth boiling several cups, then set the machine to normal mode. If this doesn’t help, it’s best to contact a specialist; maybe the problem is mechanical damage to parts of the mill structure.

There are difficulties that will require replacing individual parts to eliminate them. If you have the necessary technical abilities, you can do this at home - for most modern coffee machines, spare parts can be found in stores, on the market, and in service centers. But if water appears under the device, and you simply don’t have the skills to disassemble, replace tubes and check the density, you should immediately disconnect the device from the network and call a specialist.

Repair of Delonghi, Saeco, Krups coffee makers.

Any electronic device can fail over time. Repairing coffee makers from Delonghi, Saeco or Krups is quite easy to do yourself. This kitchen home appliance is considered one of the easiest to repair and operate.

The buttons in the coffee machine do not work

The buttons in the coffee machine do not work
If the Delonghi coffee machine or any other does not turn on, the buttons do not respond, then there may be several reasons.

First, make sure there is grain and water in the machine. Since some models do not run if they are empty.

Next look at the panel. Perhaps there is code on it that will help you understand what exactly is wrong.

And then you can carry out more serious diagnostics. Remove the front panel of the device and test the power circuit.

Sometimes the buttons just don’t work because coffee has been poured on them and they get stuck. You just need to clean up after yourself and the machine will start working.

If none of the above steps help, then you should contact the service. The coffee machine may not be working due to an electrical fault or because the fuse has blown. Such breakdowns must be repaired by a specialist.

Design and diagnostics

Before you start repairing the device, you need to find what exactly is broken in it. This will help significantly speed up and simplify the repair process. There are two types of coffee machines:

Their main difference is the operating pressure. In drip coffee makers (Bosch, Zelmer, Vitek), hot water drips through a coffee filter, through which it passes into the cup as a fragrant drink. In espresso, a stream of boiling water is poured into a cup, passing through a coffee pill (pressed ground natural coffee). The advantage of using espresso coffee makers Electrolux, Binatone, Braun, Philips (Philips) and many others is that they can work without a filter.

Photo – espresso

Capsule coffee machines for brewing coffee have a special container into which ground natural powder is poured. This allows you to brew a drink with or without pressure. The main difference between these functions is that with the help of professional carob coffee makers you can make coffee with foam.

The main difficulties of coffee machines and coffee makers of household and professional types:

The water has stopped flowing. Most likely, one of the water supply pipes is simply clogged,
The coffee began to give off a strange smell or taste. In this case, it is not always necessary to repair coffee makers yourself; maybe you just changed the coffee pills (they come in Dolce Gusto - Dolce Gusto, Nestlé, Jacobs, etc.). The next prerequisite may be a clogged filter or cheap material for the device. If the best water temperature for brewing coffee is 95 degrees, then the internal parts heat up to 125 and higher. As a result, the available plastic may begin to melt, transferring its own taste to the drink,
Cool coffee. The heating element has finished working,
Incorrect dose of water (found in capsule coffee makers). The breakdown may lie either in the engine or in the timer operation circuit,
The carob coffee maker does not turn on. There may be several circumstances: breakdown of the motor, pump, difficulties with the power cord,
You cannot adjust the brewing or cup filling time. Depending on the type of coffee maker, this may be a breakdown of the time relay, control circuit, motor (or one of its compartments).

It should be noted that after the intervention, warranty repairs will no longer be provided, so if you are not convinced of your own abilities, it is better to contact a company service center.

Extraneous noise and complete lack of work

If the coffee machine is noisy and does not brew coffee, then you should check whether the water in the device is heating. If the coffee machine takes water and heats it, but does not dispense coffee, then the cause of the breakdown may be an air lock. To fix this problem, you should run hot water through a cappuccino maker. If the coffee flows in a weak stream, then you should rinse the device completely.

If this does not help, then the coffee machine should be taken to a service center. Some models of coffee machines can independently indicate the cause of the breakdown on the display. These models are newer and more expensive.

How to disassemble a coffee maker

In order to repair all coffee makers (Nespresso, Delonghi), you will need to first disassemble them. Step-by-step instructions on how to do this:

There are set screws on the back wall of the coffee machine. They need to be unscrewed and put aside. They can be of several types: hidden, cross and cone-shaped (often found in Indesit). They are removed with a screwdriver, pliers or other suitable tools,
If the case is not removed after removing the screws, then it is secured with hidden locks. The latches are located at the bottom of the rear panel. They cannot be opened from the outside, so you will have to pry them off with a knife or screwdriver,
After removing the housing, you can begin repair work.

If the tube of Delongie, Bork, Ariete or other coffee makers is clogged, then for repair you need to use a long, narrow rubber hose. It runs along the duct and breaks through the blockage. From time to time, special brushes with a flexible stem are used for such purposes; they allow you to clean the tube and remove not only coffee, but also mineral deposits.

Cleaning the filter is a little more difficult. With frequent use, various debris accumulates on it: salt plugs, coffee dust, scale. It is necessary to clean it only according to the instructions, because otherwise, the integrity of the spare part can be compromised. Almost always, it can be wiped with a swab soaked in alcohol or another degreaser. After washing, thoroughly rinse the part.

Photo filter

There may also be difficulties with the filter if water is leaking from the coffee maker. This is often found in machines manufactured by Mulinex, Krups, Rowenta, Saego. A special valve is installed behind the filter, which turns off the water supply after the timer is turned off. If after a certain time the drink has not stopped flowing, then the prerequisite is a problem with this element. The valve may wear out after frequent use or simply cannot withstand the accumulated amount of coffee. To check and fix the breakdown, you need to disassemble the coffee machine, pour coffee out of it and inspect the valve. Please note that it is impossible to repair it, because the part changes immediately.

If the coffee maker Redmond, Spidem, Tefal, Siemens and others does not turn on, then urgent repairs are required:

First, check the power cord. It needs to be examined for a break, and the grounding must also be checked. It is connected to the terminal clamp, so be careful when diagnosing,
From time to time, household coffee machines made in China simply lose contacts. This also occurs in professional models (zauber, melitta, trevi). In this case, it is necessary to check all the places where the wires are connected to the control circuit,
Many modern cars (Senseo? Siemens, Ufesa) suffer from a bad thermostat. To diagnose it, you need to remove one wire from its end and check the contacts with a tester. If the element is working properly, the circuit should be closed,
Also, the coffee maker may not turn on if the heating element needs repair. It is called in the same way as a thermostat. For many models (Jura Impressa, Miele, Gaggia, Butler) it is made in the form of a disk, so changing it will be quite problematic; it’s easier to try to repair the part or buy a new car,
There are also certain secrets to cleaning the engine. In the care product departments, they sell special brushes that will help clean various parts of the engine without damaging the fragile material. It should be noted that in coffee makers such as AEG, Solis or Unit, the motor has several compartments, each of which can be cleaned separately.

Very interesting to read:

All about repairing a Krups coffee machine.

One of the favorites in the production of high-quality and reliable coffee machines is rightfully the popular German company Krups, which was founded about two hundred years ago. Krups coffee machines are indispensable devices for true connoisseurs of the best coffee. Using them, you can quickly and easily prepare espresso, mocha, latte, cappuccino or ice cream with an incomparable taste and smell.

Such coffee machines are characterized by the highest reliability and durability, but from time to time even with them problems occur. Therefore, every owner needs to know how to properly repair a Krups coffee machine.

The most common faults

German Krups coffee machines, subject to all operating rules, are capable of working perfectly throughout the entire warranty period. But incorrect implementation coupled with a lack of appropriate care can lead to some breakdowns and defects. More often, the following reasons lead to the failure of this device:

carelessness and rudeness when using the coffee machine,
the use of very hard water or water of unknown properties,
quite frequent and unexpected changes in electronic voltage,
the appearance of severe scale on the heating elements of the Krups coffee machine,
coffee capsules getting stuck and absolutely impossible to remove,
coffee machine falling to the floor.

When does a coffee machine need repair?

In order to find out whether a Krups coffee machine needs repair, you need to closely observe its behavior. Let's look at the difficulties that arise in most cases, as well as effective methods for solving them. If you are not convinced that you can perfectly remove faults with your own hands, photos and videos will help you.

If strong squeaks and other extraneous sounds occur during operation of the coffee machine, this indicates a malfunction of the coffee grinder mechanism.
If the device has stopped working with the functions of brewing coffee or brews it, but it is very weak and unsaturated despite the presence of all the necessary ingredients, a painstaking diagnosis is required to determine a clear prerequisite.
If leaks are detected in the Krups coffee machine, you must immediately disconnect the device from the electronic network. This discrepancy indicates damage to the tube or valve. After replacing the faulty part, you can resume implementation of the device.
If the machine has finished brewing cappuccino, the problem can be resolved by thoroughly cleaning the cappuccino maker.

If there is no pressure in the coffee machine

The essence of the problem can lie anywhere, including manufacturing defects. But don’t worry too much - initially it’s better to check whether the heating is working, the serviceability of the emergency and air valves, the adjustment of the pressure sensor, and the operation of the pressure gauge. However, most often the source is a pump malfunction.

Pump failure

The pump is the most important component of any coffee machine, regardless of its type and brand. This thing creates the required water pressure, which is supplied to the compressed coffee tablet. If it breaks, you won't drink coffee.

As a rule, all cars are equipped with similar pumps; brands’ own designs are much less common - this is mainly a priority for premium-class devices. However, this does not reduce the likelihood of malfunctions, but may complicate repairs.

Main types of coffee machine repairs

There are three main types of repair of a Krups coffee machine depending on the type of malfunction:

Regular repair of a Krups coffee machine in most cases involves performing such actions as cleaning the heating parts of the device from scale, as well as replacing some parts that have failed - clamps, tubes, gaskets, sensors, brackets, etc. This type of repair can be successfully performed without the help of others.

To carry out repairs of moderate difficulty with your own hands, you will need certain knowledge and abilities, which can be gleaned from training videos.
