In detail: do-it-yourself repair of a brown juicer from a real master for the site my.housecope.com.
After surfing the Internet and getting a lot of information, I looked for an inexpensive Moulinex Frutti Pro Plus juicer.
This miracle of technology was purchased in one of the Kaluga stores, but it did not please me for long. At first, it turned out that the filter itself does not clean itself (at least when pressing the chokeberry), so you constantly have to remove and clean it by hand. And when the next portion of rowan was squeezed out, the juice-squeezer turned off by itself and did not want to work. At first I thought that the thermal protection of the engine worked, but after an hour, the equipment still did not turn on.
And this is after 2-2.5 hours of work from the date of purchase, I am furious. At first, I didn't want to leave it in the box, take it back to the store and pop it at the saleswoman who praised it to me.
Then he cooled down a little and gave up this thought - somehow not like a man (and the saleswoman is pretty, it's a pity), washed the broken device with the thought of how I would carry it under warranty and how they would deny me this very guarantee, in general I scrolled in my mind options for a verbal skirmish (I had no doubt that it would be).
On the same day I went to see my aunt, took a juicer from her, and the next day gave the remnants of mountain ash. I didn’t take my sokozhmalku to the service, then there’s no time, then I’m reluctant to lug a large box in a transport, and it’s too far on foot. So she got it until January, and that's when I started to repair it. She died quietly, no sparks, no specific smell of burnt insulation, so I decided that either something had fallen off, or some part of the electrical circuit was out of order. I unscrew the four screws on the bottom cover and remove it.

Yes, a very complex electronic product.
Electronics ”of this juicer consists of:
2.operating mode switch low speed / high speed
3.diode, when the switch contacts are open, the diode passes only one half-wave of the mains voltage to the motor, so the motor runs at half its power, when the contacts of switch 2 are closed, all the current flows through these closed contacts in full and the motor operates at rated power
4. switch that actually turns on / off the device I want to note one discrepancy right away: the tag on the case says 400W, the engine has an inscription 600W, I didn't check which inscription is true, maybe then somehow.
Having called the entire circuit with a tester, I found a place, an open somewhere between the terminal going to the noise filter and one of the rotor brushes. So all the same the engine.
He unscrewed the four screws securing the motor to the case, unscrewed (clockwise) the drum from the motor shaft, during this operation, on the other side of the motor, a slot was made on the shaft for a screwdriver, and pulled the engine out of the case At first I thought that a thermal fuse was hidden in the stator winding, which died ...
I opened the heat-shrink tubing and found a coil that filters interference. Then I accidentally pulled the wire from this coil onto the brush, and it turned out to be torn off from the brush holder (the core was torn off, and the insulation was clamped by the brush holder petal). So this is where the dog rummaged. I soldered the wire, put the coil in heat shrinkage, checked it - it works.
I put everything back together, checked it again - and it works like that too, well, that's nice.
Fans of freshly squeezed juice and happy owners of devices for its extraction inevitably face the problem of how to disassemble their favorite juicer without fatal consequences for its functionality. There are many such household appliances on the market under different brands.
They can be made in four versions:
centrifugal type,
with auger wringing,
combined,
machines for citrus fruits.
Regardless of the model, device, brand and quality of workmanship, they all require regular maintenance. During the squeezing process, cake accumulates inside the machine, the remains of juice, which must be removed after each use. Delaying with this can adversely affect the functionality of the device, lead to its premature inoperability. Despite the reliability of the design, most branded devices may fail. Depending on the nature of the breakdown, repairs can be difficult, which will require special knowledge and the participation of an expert, or simple. In the latter case, you can do it on your own, for which you will need to dismantle the structural elements of the juicer.
To disassemble / assemble the device, you must have at least a general idea of its design. Devices for squeezing can have different designs and design features. But in general terms, their structure is about the same. Each juicer is equipped with:
housing for mounting structural elements;
metal (less often plastic) basket with a grater, where the product is chopped;
container for the accumulation of cake;
removable container for collecting juice;
lid with a hopper for loading vegetables or fruits;
pusher;
motor unit with power cable;
control unit with switch.
Careful reading of the instructions is essential for correct operation and disassembly / assembly of the unit. Our traditional disregard for this document and the desire to solve problems by the "scientific poke" method often becomes the cause of unforeseen defects and failure of the apparatus. Such a document with a translation into the consumer's language is included in the kit of any device from a more or less well-known manufacturer. It usually includes a description:
a device with a schematic or photographic demonstration of each element;
rules of use, indicating measures for safe operation;
the procedure for preparing for use;
sequence of dismantling of structural elements and their reassembly;
features of functioning.
Before disassembling the device, be sure to disconnect the power supply. This is not only moving the switch to the "off" position, but also removing the power cord from the network. The statement is banal, but relevant, given the potential danger of the device and the forgetfulness of some of the housewives. Dismantling the device for maintenance should be started only after the mechanism has come to a complete stop. In its most general form, regardless of the model, the disassembly sequence can be as follows:
removal of the pusher from the loading hopper;
removal of the cover, with preliminary detachment of the fastener;
removing the shredder;
dismantling of the container for collecting juice.
The removed elements should be washed, dried and replaced in the reverse order.
