Details: philips saeco do-it-yourself repair from a real master for the site my.housecope.com.
In order for a high-quality Saeko coffee machine to serve for a long time and without problems, it is necessary to use it correctly and maintain it correctly. However, this household appliance cannot last forever. Breakdowns or malfunctions can, at a certain moment, disable the unit for the production of a fragrant and invigorating drink. What will help in this situation? Only competent and high-quality repair of Saeco coffee machines.
The range of factors that cause breakdown of this type of household appliances include:
sloppy service;
improper operation;
the use of unacceptable varieties of raw materials;
incorrect parameter setting.
Most often, equipment repairs may be required due to improper operation of Saeco equipment. Sometimes the breakdown is provoked by the use of coffee beans of precisely those varieties that absolutely cannot be used in these models. In addition, malfunctioning of the coffee machine can be caused by incorrect parameter settings. The photo clearly shows what is happening with the unit in this situation.
Since Saeko coffee machines belong to the category of rather whimsical devices, it is optimal to entrust their repair to highly qualified professionals. However, a number of faults can be eliminated by yourself. These failures include:
elimination of the formed plaque;
the need to clean the cappuccino maker;
restoration of the lamp on the switch;
elimination of the increased noise level during the operation of the unit.
For example, you can do it yourself to remove limescale deposits from your Saeco espresso machine. To do this, it is enough to use a special video as an instruction. The elimination of the problem is accompanied by the use of special tablets and liquids. You can also use other compositions that help to remove residual oils from the internal structure of the unit.

You can clean the cappuccino maker yourself. For this, it is recommended to use special tools. The photo shows the most effective formulations for carrying out this kind of work.
It is also very important for the owners of such household devices to take into account that the repair of the Saeko coffee machine can be omitted if diagnostics are carried out in a timely manner. It is also worth using only clean water during the preparation of the product. There is no need to ignore the instruction. By following the rules in place, you can avoid malfunctions.
The user can repair the switch with his own hands if it stops working. Sometimes it is enough to check the correct connection of the Saeko coffee machine to the network. The photo shows perfectly how the connection should look like, ideally.
Another commonplace malfunction is the inability to pour a drink. To eliminate the problem, sometimes it is enough just to check the correct installation of the capsule in the device. The lid in the brew area must be tightly closed and the water container must be completely filled with liquid. If the pump is operating too loudly, you should check the correct position of the container with water. In this case, the container must also be filled. Sometimes it is necessary to descale the components of your Saeco espresso machine. How to do this work can be seen in the photo.
A self-repair unit from the manufacturer Saeco can be made when:
the coffee is barely warm;
water flows from the device;
the mechanics does not function.
If the drink prepared in your Saeco espresso machine is not hot, it is recommended to warm up the cup first.During this manipulation, you should check whether scale has formed. In the photo you can see how this procedure is performed. Self-repair of the device can also be carried out in the event of a water leak. The Saeco-branded device sometimes accumulates liquids in the compartment reserved for used capsules. In this situation, you will need to evaluate the correct installation of the capsule in the coffee machine.
If the leak is not eliminated by this method, do not experiment any more. It is best to contact a service center specializing in the repair of Saeco espresso machines. Experts recommend that you give up the temptation to open the body of equipment on your own. Such a decision can result in irreparable consequences for the owner of the device. Disassembling a Saeco machine requires skill and experience. Otherwise, the equipment may be irretrievably damaged and broken.
Do-it-yourself Saeco coffee machine repair is quite difficult due to the non-separable body. You must first unscrew the lid, take out all the giblets and only then investigate what is broken there. To repair such a unit, you must first figure out how it works. For example, let's take the Saeco Vienna coffee machines, consider its structure, principle of operation and design features.
The functionality of such coffee machines is as follows:
Coffee grinding.
Brewing coffee.
Making milk froth.
Also, this model is able to brew instant coffee and prepare a drink from ground grain. Instant or ground coffee can be poured into the container where the beans are poured. In this case, the taste may change due to a dosage violation. Dosing of ground coffee is as follows: when a signal is received that it is necessary to brew coffee, a special motor moves the cup up to the stop. At this moment, there is about 8 grams of ground coffee in the bowl. Why about? Yes, everything is simple - there is a special handle with which you can adjust the amount of ground coffee beans in the cup. The handle pulls the spring through the rod, which acts on the balancing mechanism. If there is instant coffee in the grinder, the system will simply pass it through the millstones and ship exactly as much as is needed to balance the mechanism. Since Vienna Plus has the ability to adjust the concentration of the drink, it can be assumed that it knows how to work not only with fried grains. But it is undesirable to pour green coffee into it - it just overheats during the grinding process and loses its beneficial properties.
The coffee grinded by the grinder falls onto the bowl, which moves inside the cylinder. When the mechanism signals that there is enough ground coffee in the cup, the automatic system is triggered and the servo drive starts to work. Further, the cylinder turns to the side and begins to move towards the stop. In the same place, brewing takes place, at the end of which, at the end of which, the mechanism performs the opposite action. In the course of the reverse movement, a special mechanism with a lid removes the resulting waste coffee washer and throws it into a special container.
Water moves along a very simple route - from the reservoir it is through a pump under pressure up to 20 atm. (which I personally doubt, since the body and pipes are made of plastic) gets into the boiler. The boiler itself is round, around the perimeter of its bolt holes. A heating element is attached to one of the parts from the inside. There is also a temperature sensor, which, in fact, is a bimetallic plate. The tension is adjusted with a special knob, as a result of which the response threshold is changed. This is necessary in order to be able to receive steam, the temperature of which is 127 degrees Celsius, and this despite the fact that in normal mode coffee must be brewed at a temperature of 95 degrees. To prevent water from returning back, there is a check valve at the inlet, and a bypass valve is installed at the outlet. Steam or water moves through it. Depending on what is being prepared at the moment.It is enough to turn the regulator to the position of water or steam - and the valve will operate in the required mode.
Now we put everything together - the pump pumps water from the reservoir into the boiler, where the latter heats up to the desired temperature. The desired temperature is determined by the position of the knob that regulates its tension. Then the plate is triggered, the contacts of the heating element open, at the same time the signal light comes on. After the indicator has reported that the desired temperature has been reached, you need to press the button and get the finished drink.
Do-it-yourself Saeco coffee machine repair begins with its disassembly. This is done according to the following algorithm:
The front cover is removed.
The compartment in which the waste is stored is removed.
The stand for mugs is removed.
The water tank is dismantled,
The cover of the bean compartment is removed.
Then, in the compartment itself, you need to unscrew the screws and remove it out. Next, another self-tapping screw is unscrewed from the end.
Sometimes there is an extra screw that is sunk. Don't miss it. Next, open the front cover, and unscrew 2 more screws near it, which also need to be unscrewed. The next step is to remove the top cover. Be careful here as there is a hose attached to it. Disconnect it and then remove the front door. Judge everything. It remains only to remove the automation outside.
Saeco Vienna power supply.
Since such a complex device contains several motors, there must also be a power supply unit that provides electricity to them. Taking a quick glance at the power supply system, we can say with a high degree of confidence that a pulse-type power supply unit is used here, since there are several filters at the input, there is a transistor with a radiator in the power circuit and the tracks from the microcircuit, which is the RF pulse generator, are connected to it. This microcircuit is supplied with power from the diode bridge, there is also a filter. The overheating protection system contains varistors and fuses.
Further, from the RF pulse generators, the signal goes to the base of the transistor, which regulates the supply of current to the transformer. As a result, we have RF pulses at the output, which in turn can be rectified. The rectifier is a Schottky diode bridge. That's basically it. Summing up, we have - the current is fed through the transistor to the transformer and then rectified. The transistor is controlled by a microcircuit on the keys, which is a generator of high-frequency pulses. As a result, the primary winding receives not a current of 220 V 50 Hz, but high-frequency pulses, the amplitude of which depends on the value of the sinusoid. With such a minimum set of knowledge, you can do diagnostics and start repairing your saeco coffee machine with your own hands.
The pump is running, water is not flowing.
The valve is out of order. The bypass breaks down more often.
First of all, we check the voltages at the input and output of the transformer. Next, we look at the motors and their control chain. But such breakdowns are not so frequent - the mechanics in these coffee machines are quite reliable. Repairs may involve adjusting the dispenser.
So, having looked at the general structure of the Saeco Vienna coffee machines, we believe that you can do it yourself at home and enjoy good coffee.
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, and 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 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.
