In detail: do-it-yourself saeco coffee maker repair from a real master for the site my.housecope.com.
Coffee is one of my favorite drinks, and besides, on this drink I also earned a little. Let me explain how: there are inexpensive Saeco coffee makers (for example Royal, Viena or Magic), which have a huge resource of work (One of my coffee makers made 16000 without any major repairs and problems). So, I used to buy such coffee makers and rent them out, or I supplied coffee and consumables, and I got money from the portion. I gained a little experience, and decided to share with you, perhaps this information will be useful.
There are few breakdowns in such coffee makers, since their design is as simple and reliable as possible.
Most of the breakdowns are caused by improper use, unstable voltage and "hard" water.
I will name and briefly describe the breakdowns of Saeco coffee makers, and how you can solve them yourself. In short, because I will describe the specific breakdown in more detail in new articles, where there will be a master class on disassembling Saeco coffee makers, replacing parts, repairing ...
Let's take the most common and simple Saeco Viena as an example.
- Power is not being supplied.
The power cord or plug is damaged. You need to check the presence of voltage in the outlet. Solution: To do this, plug another known working device into the outlet, or use a tester. If other devices work, then you can check the cord itself by external inspection (for mechanical damage) or when disassembling the coffee maker.
- The front door of the Saeco Viena is not closed.
This is also a common reason. After cleaning the working unit or during transportation, there are situations when the door opened slightly and thus turned off the power circuits. How to repair: open and close the front door of the coffee maker. When fully closed, the door should fit snugly against the body (it is fixed with two magnets - on the body and the door).
Video (click to play).
- A power surge has blown the fuse.
This issue needs to be resolved only with a full or partial disassembly of the coffee maker (in the next articles we will do all this). Fuses can be located on the board, on the wires (depending on the model).
Breakdowns with the board (rarely), stabilization unit (extremely rare) or with internal wires are also possible. We will consider all these breakdowns and repairs of the Saeco coffee maker with our own hands in the following articles. If you have any questions or additions, write to us by mail, we will definitely publish the answers to them.
Coffee makers of various types are permanently operated equipment. If the coffee machine breaks down, the schedule also changes. It is difficult to work in the usual rhythm without drinking your usual morning coffee. The reasons for the breakdown are different, from an unsuccessfully purchased model to poor maintenance of the unit. Most faults can be rectified by yourself. If the control unit breaks down or the board burns out, you cannot do without the services of the service center.
The simpler the mechanism, the less malfunctions it can be. Repair of drip coffee makers consists in flushing the filter mesh from accumulated oils. When using tap water, the tubes become clogged with scale. It is enough to buy a special product and, according to the instructions on its packaging, rinse the drainage system. It is not worth saving and replacing the special composition with vinegar. Soon he will have to change the gaskets, which he will corrode.
When the drip coffee maker has stopped heating, you need to check the wire and contacts. If they are in order, then the heating element has burned out. Replacing it will cost more than buying a new coffee maker of the same type.
Most of the problems with capsule coffee makers are related to coffee pills:
incorrectly inserted;
other firm of the capsule;
the lever is weakly pressed.
It is necessary to buy only tablets of the same brand as the coffee maker, carefully throw their piercing mechanism and press the lever rather sharply. If this does not help, the mechanism should be disassembled and cleaned.
In carob models, the sealing is most often violated. Water begins to drip from under the horn. The reason is the O-ring is dirty, or it is destroyed. The ring must be rinsed. Replace if cracked. You can not put car pads, and from washing machines. In them, rubber has a different composition, it is toxic to food.
Spout leaks are more common in DeLonghi coffee makers than others. There is no need to rush to the service center, repairing a Delongy model coffee machine with your own hands is quite simple. A detailed description with diagrams is in the technical passport for the car.
Each model has its own weak points. Clogged filter becomes the most common cause of malfunctions in the machines "Saeko Minuto", "Roventa", "Nescafe Dolce Gusto", "Krups ».
Changing the high pressure pump is most often necessary for Vitek coffee makers. The coffee starts to flow poorly and does not brew well.
Coffee machines "Saeko", "Delong", "Philips" have a complex electronic system and a drive that is sensitive to voltage surges. They have disposable overload protectors installed inside them. When a power surge occurs in the network, protection is triggered and they no longer start. Dismantling and replacing the fuses of the Saeco Minuto espresso machine with your own hands is possible if you have spare parts and knowledge of electrical engineering.
The main reasons for the breakdown of coffee makers of all types are the same:
filters are clogged;
using untreated tap water;
power surges;
neglect of equipment;
lack of regular cleaning;
wear of parts during long-term operation.
If the coffee maker breaks down, you need to disassemble it, rinse and clean it, check the integrity of all seals and parts. After that, in most cases, the unit starts to work.
Before repairing, you should analyze the type of failure, and the possibility of self-troubleshooting in the Dolce, Delong and others devices.
To repair Saeco coffee makers, be aware that the casing cannot be disassembled. The cover is secured with several screws. First you need to remove it, then dismantle the teapot and other units through the top. It is inconvenient to do this, it is necessary to put screwdrivers and various stops.
The main reason is that the filter is clogged or an air lock has formed in it. If your pump works and no water flows, try fixing it yourself. You need:
Open the lid of the water tank. Pull out the filter carefully. On some models, you need to slide the release latch.
Clean the filter.
Turn it upside down with the inlet and outlet tubes. The filter is completely filled with water.
Fill the tank and refit the filter under water.

Foam is weak or hot milk is pouring into the cup instead. The reasons for the breakdown are simple:
the quality of the milk does not match;
poor care - tubes clogged.
VIDEO
Milk should be taken only pasteurized with a fat content of 2.5% to 3.5%. You can not pour powdered milk and just boiled, fatty. After each cappuccino, the pipes and the cappuccino maker should be rinsed under warm running water for about 3 minutes so that all the fat is rinsed out.
Remove the grinder and check the flow of beans into the grinding compartment. Clean the funnel and adjust the grind. Very fine and coarse coffee can clog the millstones. From the oil contained in the grains, a coating is formed, which prevents the passage of the powder.
If, after cleaning, the grains do not enter the grinding department, the help of a specialist is needed.
VIDEO
Water leaks from under the horn, collects under the coffee machine, check the O-rings. They often get ground coffee, grease and dirt. The tightness is broken and steam escapes.On the DeLonghi model, the instructions draw the attention of buyers to respectful treatment of coffee machines. They collect water in the sump and under the machine itself.
Open the housing, remove the coffee unit and check the O-ring. Remove it, rinse it, clean the entire unit and reinstall it. If cracks form on the ring, you need to buy a new one. To do this, you should take your passport to a specialized store. Rings from equipment from other companies will not work. They will be rougher or softer than other sizes.
The cone filter should be rinsed. If it is clogged, steam supplied under high pressure finds its way out in a weak spot. By analogy, the brewing unit in the coffee machine is checked, all pipes are cleaned.
VIDEO
Leaks must be repaired in time. There are many electrical equipment inside the machine. If water gets on it, a short to the case and an electric shock may occur. In the best case, the engine or board will burn out.
Check everything from the socket to the power button. To do this, use an indicator screwdriver and a multimeter. Broken and dirty contacts must be cleaned up. If the mains voltage is low, the equipment will not work.
If the coffee maker has been running and switched off before, check the thermal protection.
Coffee flows in a thin stream or does not drip at all, you should start by rinsing and cleaning all pipes and assemblies from salts, grease and dirt. The machine hisses, steam rushes out and does not enter the brewing unit, it is necessary to decalcify - descale. For this, a special composition should be used. As a last resort, a citric acid solution, and rinse well afterwards. You cannot rinse with vinegar.
All components should be cleaned of coffee dust, oils and dirt. If after this the problem persists, you should contact the service center.
VIDEO
Various breakdowns are highlighted in codes on the display. Their designation can be found in the operating instructions. It also shows how to fix the equipment with your own hands.
VIDEO
If the breakage given by the display does not exist, it is necessary to check the water level, heating and pressure sensors. The signals on the display are given by the control unit based on the readings of the sensors, starting with the float and ending with those located in the container.
Extraneous noise appears inside the coffee maker during its operation, while the quality of the drink deteriorates, the cup is filled to half, other problems appear - the system should be flushed. It is better to do this using a special cleaner for coffee machines.
It is necessary to remove all blocks, rinse filters, coffee grinder, steam pipes. It is necessary to check the bunker for the disposal of cake, pay attention to the strength of fixation of various units, the presence of foreign objects. Weed can be removed with a toothpick. You cannot use a metal tool. It will scratch the smooth surface and the ground coffee will become clogged more often.
The filter may become clogged if the coffee is ground very finely. Dust enters the cells and clogs them. It is necessary to manually adjust the grinder by increasing the size of the fraction of ground beans.
If there is extraneous noise, the machine does not work even after cleaning - take it to the service center, let the specialists do it.
The water is heated by a heating element located at the bottom of the coffee maker. If the water does not heat up and steam does not form, check the heating element with a multimeter. TEN refers to expensive parts. On simple coffee makers, its cost and replacement services can be equal to the price of a new unit.
The buttons are pressed and there is no reaction. Need to check:
the presence of water in the tank;
the buttons are clean or filled with coffee;
is there any grain in the container;
the machine is connected to the network;
no kinks in the wire.
When checking the wire and plug, disconnect the machine from the power supply. If you have a multimeter and know how to use it, you should ring the contacts on all buttons. Before that, rinse the buttons themselves with alcohol using a cotton swab. If they were covered with coffee or something else, they may stick.
VIDEO
Having done everything possible and not fixing the unit, it is necessary to call specialists.
The coffee is poured into the container, but the machine cannot see it. There are several reasons for the failure:
the internal mechanism is covered with coffee dust due to a breakdown of the coffee maker;
coffee has entered the engine compartment;
the funnel of the coffee maker is clogged;
the control unit has broken.
VIDEO
The repair should begin with cleaning all the components, the funnel of the coffee maker, the coffee grinder. If coffee gets into the engine, it must be changed. Inquire, it may be cheaper to buy a new unit. The control unit will be replaced at a service center.
Having carefully analyzed the cause of the breakdown, rinsing and cleaning the unit, the coffee maker in most cases can be repaired by hand. The main causes of malfunctioning are improper care and neglect. It is necessary to study the instruction manual and comply with its requirements.
Do-it-yourself Saeco coffee machine repair is difficult because the body is not separable. The cover is removed from above, the master unscrews a bunch of screws ... the insides of the heavy unit are pulled up. The procedure is dreary, experienced repairmen help with a screwdriver, the authors just pretend: the action is not easy. The review will first consider the principle of operation, the features of the Saeco Vienna coffee machines, then the procedure for disassembling the units, to top it off, let's say a few words about the internal structure. After reading the first two sections, the third is not needed, the mechanics, the electrical part are devoid of complexities.
Saeco will always help you identify the problem with the error codes. Few electronic components that cannot be replaced. Rewind the motor windings, the magnetic shaft rarely breaks. A typical housewife can clean the boiler.
Saeco Vienna coffee machines in question are able to:
Grind coffee.
Brew ground coffee.
Make milk froth by preparing various drinks.
The Saeco Vienna coffee machine can brew ground, instant coffee. Undoubtedly. Pour the powder into a container for beans, however, the strength of the drink may differ slightly from the usual one. Coffee machines dispense the amount of beans / water, pouring powder inside does not mean that you will get the wrong drink with a high degree of probability. The result will be different from the traditional one. The dosing process is hushed up by the instructions. An instructive video was posted on YouTube: a repairman details the functioning of the Saeco automatic coffee dispensing group, saying the following:
The coffee machine "says" to the coffee dispensing group: it's time to brew, the engine sets in motion the mechanism that moves the cup to the position on the cylinder, pushes it up, reaching the stop.
The specialist continues to say: 8 grams of ground coffee is placed inside. The video describing Vienna Plus allows you to understand: setting, batching are carried out by mechanical methods. The plus sign means: in the model, the dose is changed, it is done with a special handle that rotates the outer nut of the coffee grinder by means of a rod with a gear. That is balanced by a spring, the preload is changed by a regulator. Vienna uses a similar mechanical tuning scheme. Throw in instant coffee inside - it will pass through the millstones, settle in the cup. The process continues, the mass reaches critical, "the coffee machine tells the coffee dispensing group: it's time to brew."
By purchasing the Vienna Plus model, we get the opportunity to dose the taste by changing the concentration. The coffee machine does not strictly work with roasted beans. Avoid putting green coffee inside, the reason is simple: the beneficial properties will be lost, destroyed by heat, the operation is meaningless. Will the Saeco Vienna Plus espresso machine work. Of course, yes, the millstones do not care what to grind, brew, even walnuts. The Saeco coffee dispenser is fully automated:
The ground coffee is poured onto a flat bowl that runs inside the cylinder.
After the end of grinding, a mechanical signaling device is triggered, starting the servo drive.
The piston with the cylinder falls to one side, begins to move along the runners towards the stop, where the brewing will take place.
After the end of the procedure, the piston, the cylinder begin to move back, the inclined cover is triggered, becoming perpendicular to the plane of movement, removes the tablet, dropping it into the waste material receiver.
Many people are hindered from sleeping at night by the question: is it possible to use the favorite method of Russians, to brew used tablets again. The Saeco Vienna coffee machine will master the technology! Avoid actions. Coffee grinder motors, coffee dispensers are separate. The first one simply threshes in one direction, the second one can rotate the shaft on reverse.
The path of water movement is relatively simple - those who have mastered a couple of reviews of the VashTechnik portal on the topic of water heaters will find it. From the container, water is drawn by a pump. According to the manufacturer, the pump is capable of creating a fabulous pressure of 15–20 atm, the compressor casing is plastic, like a tube. Raises doubts about the incredible performance, the technical rationale for the strength of the structure exceeds the scope of the review.
The boiler is formed by two halves, bolted together, running along the perimeter. Looking from the side of the heating element - the tank of the Saeco Vienna coffee machine resembles an iron. Applies to a spiral that is bolted to one half. The similarity is completed by a bimetallic plate, which serves as a temperature sensor; the tension is changed with a special handle. To obtain steam, it is necessary to see the presence of 127 ºС, 95 ºС is enough for brewing. There should be no boiling water in the latter case. It is associated with the quality of the resulting drink. Take note when using instant coffee, an electric kettle with a thermostat (see Vitek).
The boiler inlet is protected by a non-return valve that blocks the return flow of water. The outlet is guarded by a by-pass valve that releases water for brewing and receiving steam. Which process will take place is determined by the position of the water / steam regulator. Just a knob switches the outlet of the bypass valve, supplying the desired channel. The device of the Saeco Vienna coffee machines is primitive:
water is pumped up by a boiler;
the temperature reaches the desired value;
a bimetallic plate is triggered, opening the contacts of the heating element, lighting the button lamp;
pressing the key will allow you to get coffee, make froth.
Do-it-yourself Saeco espresso machine repair begins with disassembly. The order is as follows:
The front cover opens.
The waste collection container and coffee dispensing spout are removed.
Then the mug holder with the tray is pulled out.
The container for water is removed from the back, the cover of the bean compartment is removed.
Screws are unscrewed in the grain compartment, the assembly is removed.
Another screw on the curb is unscrewed under the water tank.
Then the front cover opens, if you look from below, you will see a couple of screws - they are unscrewed.
Behind the grain compartment, another screw secures the rear wall curb, recessed down. Unscrews if available.
Remove the top cover of the Saeco Vienna espresso machine. The water hose is attached, undock.
Remove the front door using a screwdriver.
Now we remove the insides from the deep bottom of the Saeco Vienna coffee machine. Not an easy task, be careful.
The eligibility for warranty repairs for Saeco espresso machines is no longer valid. Avoid opening the device with a valid free service period.
From what has been said, it is clear: inside the Saeco Vienna coffee machine there are two or three engines that need to be powered. Why did they decide to fence a garden for motors? And inside there is nothing more that requires frills: the heating element operates from 230 volts, LEDs too, the bimetallic plate does not need power at all. The rest is mechanics. Recall that the buttons are not touch-sensitive Saeco Vienna coffee machines, therefore, where to put the generated current.
VIDEO
The power supply unit resembles an impulse type in appearance. It is not too important for the repairman, we will just discuss what is included in the composition. The transformer is powered by a power transistor that controls a high-frequency pulse generator (a common miniature microcircuit).The input was chosen by numerous filters formed by capacitors, resistors, and chokes. The generator is powered by a rectified, stabilized diode voltage through a smoothing filter. Fuses are not located in the main transformer circuit, they are powered by varistors if the circuit overheats. The protective element is often a low-resistance resistor that burns out when the current load is exceeded. At the same time, the element limits the amperage of the circuit elements. The radio element protects the primary winding circuit of the transformer, it has nothing to do with varistors.
The high frequency generator voltage supplies the base of the power transistor. High-frequency pulses are formed, passing through the transformer, filtered, rectified, if necessary, by Schottky diodes. The type of radioelements was chosen due to the minimal drop of the direct connection of the p-n-junction.
With the description in hand, repair your Saeco Vienna espresso machines without the hassle. Also, with some degree of certainty, you will understand the cause of the breakdown without opening the case. The pump is working, there is no water - the valve has broken, rather the bypass. Electrical problems: motors, power supply. The mechanics are relatively reliable and the dispenser will have to be adjusted. We believe readers will fix the Saeco Vienna coffee machine with their own hands.
Any electrical device can fail over time. Repairing coffee makers from Delonghi, Saeco or Krups is quite easy to do with your own hands. These kitchen appliances are considered one of the easiest to repair and operate.
Before you start repairing the device, you need to determine what exactly broke in it. This will greatly speed up and simplify the repair process. There are two types of coffee machines:
Their main difference is the working pressure. In drip coffee makers (Bosch - Bosch, Zelmer - Zelmer, Vitek - Vitek) hot water drips through the coffee filter, through which it passes into the cup, already being a fragrant drink. In an espresso, a stream of boiling water is poured into the cup, passing through a coffee tablet (compressed ground natural coffee). The advantage of using espresso machines - Electrolux, Binatone, Braun, Philips (Philips) and many others - is that they can work without a filter.

Capsule coffee machines for brewing coffee have a special container into which ground natural powder is poured. This allows brewing a drink with or without pressure. The key difference between these functions is that with professional espresso machines, you can make a frothy coffee.

Main problems coffee machines and coffee makers of domestic and professional type:
The water stopped flowing. Most likely, one of the pipes supplying water was simply clogged;
The coffee began to give off a strange smell or taste. In this case, it is not always necessary to repair the coffee makers yourself, perhaps you just changed the coffee tablets (they are Dolce Gusto - Dolce Gusto, Nestlé, Jacobs, etc.). Another reason can be a clogged filter or cheap material for the device. If the optimum water temperature for brewing coffee is 95 degrees, then the internal parts are heated to 125 and above. As a result, the cheap plastic can start to melt, imparting its taste to the drink;
Cold coffee. The heating element stopped working;
Incorrect dosage of water (found in capsule coffee makers). A breakdown can occur both in the engine and in the timer circuit;
The espresso machine does not turn on. There may be several reasons: breakdown of the engine, pump, problems with the power cord;
You cannot set the brewing or filling time of the cup. Depending on the type of coffee maker, this may be a breakdown of the time relay, control circuit, engine (or one of its compartments).
It is worth noting that after the intervention, warranty repairs will no longer be provided, so if you are not confident in your abilities, it is better to contact the branded service center.

In order to repair any coffee makers (Nespresso - Nespresso, Delongy), you will need to disassemble them first. Step-by-step instructions on how to do this:
There are set screws on the back of the coffee machine. They need to be untwisted and put aside. They can be of several types: hidden, cruciform and cone-shaped (often found in Indesite). They are removed with a screwdriver, pliers or other suitable tools;
If, after removing the screws, the case is not retracted, 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 have to pry them with a knife or screwdriver;
After removing the case, you can start repair work.
If the pipe is clogged at Delongey, Bork - Bork, Ariete - Ariete or other coffee makers, then you need to use a long thin rubber hose for repairs. It starts up along the duct and breaks through the blockage. Sometimes for such purposes, special brushes with a flexible leg are used, they allow you to clean the pipe 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 should be cleaned only according to the instructions, since otherwise, the integrity of the spare part may be damaged. In most cases, it is allowed to wipe it with a swab dipped in alcohol or other degreaser. Rinse the part thoroughly after rinsing.
Photo - filter
Also, problems can be associated with the filter if water leaks from the coffee maker. This is often found in machines manufactured by Moulinex, Krups, Rowenta, Saego. A special valve is installed near the filter, which, after turning off the timer, turns off the water supply. If after a certain time the drink has not stopped flowing, then the cause is a malfunction of this element. The valve may wear out after frequent use, or it may simply not be able to handle the accumulated amount of coffee. To check and fix the breakdown, you need to disassemble the coffee machine, pour the coffee out of it and inspect the valve. Please note that it cannot be repaired, so the part changes immediately.

If the coffee maker Redmond, Spidem, Tefal, Siemens and others does not turn on, then urgent repair is required:
The first step is to check the power wire. It needs to be examined for an open circuit, and also to additionally check the grounding. It connects to the terminal block, so be careful when diagnosing;
Sometimes, household coffee machines made in China simply lose contacts. It also occurs in professional models (zauber, melitta, trevi). In this case, you need to check all the places where the wires are connected to the control circuit;
Many modern cars (Senseo¸Siemens, Ufesa) sin with a low-quality thermostat. To diagnose it, you need to remove one wire from its end and check the contacts with a tester. With a serviceable element, the circuit must 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 it will be rather difficult to change it, it is easier to try to repair a part or buy a new car;
There are also certain secrets to cleaning the engine. In the departments of caring products, special brushes are sold that will help clean different parts of the motor without damaging the fragile material. It should be noted that in AEG, Solis or Unit coffee makers, the motor has several compartments, each of which is cleaned separately.

Very interesting to read:
Most of the problems arise due to the fact that a modern coffee brewing machine is an extremely technological device, the operating parameters of which are precisely calculated.Therefore, any violation, whether it be hard water, capsules not recommended by the manufacturer, or other grinding of grains, make it necessary to repair the apparatus or understand how high-pressure systems work. But most of the simple problems can be fixed at home as well. Consider how to repair a coffee maker with your own hands.
If it is decided to independently investigate the coffee maker and carry out repairs, then it is worth taking basic safety measures:
The device must be disconnected from the network.
You need to work with a tool with insulated handles.
Water and wet hands are potential hazards.
Disassembling the body of most coffee makers is not difficult. Often it is enough to unscrew a few screws on the back cover. This makes it possible to gradually disassemble the device into units or large parts. At the same time, there are subtleties: in Delongy's cars, the bolts located on the lower part are closed with plugs or are under the rubber feet , and many Saeko models additionally require the removal of fasteners to remove individual blocks that open access to the areas needed for repair.
VIDEO
In order not to be mistaken, refer to the help information. If the coffee maker does not lend itself to logic and does not understand, it is better to look for data on the model on the Internet.
Many devices, in addition to the self-tapping screws on the back of the case, also have latches that hold the top cover or bottom.
To find such a fastener, you will need a thin screwdriver or knife, which passes the line of the joint of the parts until the localization of the zone where you can press the latch.
Models with VT1513 and VT1511 are leaders in the problem of violation of the fluid supply regime. These are extremely convenient coffee makers operating under a pressure of 16 atmospheres and allowing you to prepare delicious espresso. However, even the slightest mismatch in the grind, as well as the use of hard water, can cause problems with the fluid supply.
If the grinding is too fine, the screens and filters are clogged on the Vitek VT1511 and VT1513 models. If you use too large, the drink will not brew. Hard water will clog the high pressure pipes. And all this leads to serious breakdowns - failure of the injection pump or cracking of the plastic switch block.
Vitek VT1513 Coffee Maker Pump
To carry out maintenance or repairs, you must first disassemble the device:
The top aluminum lid is removed where the cups are located.
The fastening screws hidden under the rubber pads are found.
Self-tapping screws are removed, the back cover is removed, giving access to all nodes.
Potential breakage areas can be seen immediately. High pressure tubes are hard, thin. The feed selector is a small plastic block that the distributors fit into. The blower is a round metal pump. To repair the Vitek coffee maker you will need:
Assess the condition of the high-pressure pipes, check the places of their fixation - there should be no looseness, cracks.
Check the condition of the blower housing. Splits or traces of overheating indicate a possible pump malfunction.
Inspect the condition of the feed switch.
VIDEO
If, after assessing the reliability of contacts, the problem is still not clear, carry out the following operations:
Clean the high pressure pipes. For this, you can use thin rubber tubes or a single-core wire with soft insulation. There is also a special tool - a flexible brush.
Check fasteners and contacts, remove all dirt.
Clean the filters.
After that, the coffee maker starts up and is re-checked for the operability of the nodes. By the way, the most common accident is crack in switch , it is determined by the presence of water on the surface of the part. The damage cannot be sealed (pressure will squeeze out any sealant). Therefore, it is worth replacing the block or simply melting the crack, heating a knife or screwdriver on the gas burner.
Breakage of the Vitek VT1513 mode switch
If disassembly, cleaning, visual inspection of the coffee maker did not allow to localize the problem, most likely, the matter is in the blower, and it is necessary to call a specialist.
There are many common breakdowns. It is not difficult to repair them with your own hands. For instance:
A common problem with Moulinex, Krups, Roventa, Saeco devices is clogged filter ... Water can flow from the coffee maker, coffee can be dispensed without stopping, or vice versa - it can run out in small quantities. The reason is a clogged filter or a failure of the pressure valve built into it.
Oxidation of contacts became more and more common, as manufacturers began to save every penny in production. Obligatory cleaning and regular checking of contacts is the key to the successful operation of the coffee maker.
Failure of the heating element ... Repairs in this case must be carried out by a specialist. Since there are models of coffee makers, the heating element of which cannot be dismantled without damaging other parts. The cost of work and the purchase of a new spare part will cost more than a new device.
The main part of the repair is a thorough cleaning of all nodes and contact groups. Without carrying out this operation, there can be no question of any thorough testing of the electrical parameters of motors, temperature sensors, electronic units. These actions will be ineffective to say the least.
Each coffee maker comes with an instruction manual. It describes the typical problems of a particular model and provides ready-made recipes for solving them. Often these are instructions like "the coffee maker won't turn on - check the wire." Yes, the integrity of the power cable, the absence of scuffs, fractures, mechanical damage - this must be checked without fail.
VIDEO
However, the general principle of repair is reduced to moving from simple to complex. Something does not turn on - the functionality of the button is checked, the cleanliness and reliability of the contact. The operating parameters do not correspond to the expected - the regulators and sensors are closely examined, cleaned, lubricated, if necessary, replaced. To eliminate common malfunctions of coffee makers, you need to act on the principle of a thorough inspection of parts for damage, full service of all filters, pipes, contact groups and sensors.
A coffee maker is an indispensable device in modern life, but the complexity of its device implies strict adherence to the manufacturer's recommendations. In order to constantly enjoy a fragrant drink, use coffee of the correct grinding, a certain type of capsule, and also periodically service the machine.
Any electrical device can fail over time. Repairing coffee makers from Delonghi, Saeco or Krups is quite easy to do with your own hands. These kitchen appliances are considered one of the easiest to repair and operate.

Cold coffee. The heating element stopped working;
Incorrect dosage of water (found in capsule coffee makers). A breakdown can occur both in the engine and in the timer circuit;
The espresso machine does not turn on. There may be several reasons: breakdown of the engine, pump, problems with the power cord;
You cannot set the brewing or filling time of the cup. Depending on the type of coffee maker, this may be a breakdown of the time relay, control circuit, engine (or one of its compartments).
It is worth noting that after the intervention, warranty repairs will no longer be provided, so if you are not confident in your abilities, it is better to contact the branded service center.

In order to repair any coffee makers (Nespresso - Nespresso, Delongy), you will need to disassemble them first. Step-by-step instructions on how to do this:
There are set screws on the back of the coffee machine. They need to be untwisted and put aside. They can be of several types: hidden, cruciform and cone-shaped (often found in Indesite). They are removed with a screwdriver, pliers or other suitable tools;
If, after removing the screws, the case is not retracted, 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 have to pry them with a knife or screwdriver;
After removing the case, you can start repair work.
If the pipe is clogged at Delongey, Bork - Bork, Ariete - Ariete or other coffee makers, then you need to use a long thin rubber hose for repairs. It starts up along the duct and breaks through the blockage. Sometimes for such purposes, special brushes with a flexible leg are used, they allow you to clean the pipe 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 should be cleaned only according to the instructions, since otherwise, the integrity of the spare part may be damaged. In most cases, it is allowed to wipe it with a swab dipped in alcohol or other degreaser. Rinse the part thoroughly after rinsing.

Also, problems can be associated with the filter if water leaks from the coffee maker. This is often found in machines manufactured by Moulinex, Krups, Rowenta, Saego. A special valve is installed near the filter, which, after turning off the timer, turns off the water supply. If after a certain time the drink has not stopped flowing, then the cause is a malfunction of this element. The valve may wear out after frequent use, or it may simply not be able to handle the accumulated amount of coffee. To check and fix the breakdown, you need to disassemble the coffee machine, pour the coffee out of it and inspect the valve. Please note that it cannot be repaired, so the part changes immediately.

If the coffee maker Redmond, Spidem, Tefal, Siemens and others does not turn on, then urgent repair is required:
The first step is to check the power wire. It needs to be examined for an open circuit, and also to additionally check the grounding. It connects to the terminal block, so be careful when diagnosing;
Sometimes, household coffee machines made in China simply lose contacts. It also occurs in professional models (zauber, melitta, trevi). In this case, you need to check all the places where the wires are connected to the control circuit;
Many modern cars (Senseo¸Siemens, Ufesa) sin with a low-quality thermostat.To diagnose it, you need to remove one wire from its end and check the contacts with a tester. With a serviceable element, the circuit must 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 it will be rather difficult to change it, it is easier to try to repair a part or buy a new car;
There are also certain secrets to cleaning the engine. In the departments of caring products, special brushes are sold that will help clean different parts of the motor without damaging the fragile material. It should be noted that in AEG, Solis or Unit coffee makers, the motor has several compartments, each of which is cleaned separately.
