Do-it-yourself Samsung washing machine repair
Since it is necessary to get to the drum of the machine to replace the bearings, it is necessary to disassemble it completely. Some models have a special cover on the back of the case, which provides access to the motor, belt indiscriminately. However, my model had to be completely disassembled. To do this, you need enough space so that it is more convenient to work and expand the parts.
Let's start disassembling. You must first remove the top cover, which is attached with two self-tapping screws from the back. To remove the cover, you must move it away from the face of the machine and lift it.
Remove the washing powder tray. The container is removed and three hoses are disconnected from it, they are clamped with metal clamps. It is convenient to open these clamps with pliers.
After removing the cover, a large counterweight immediately catches your eye. The names of the parts are mine, since I do not know what they are actually called, but I think everything will be clear to you. Remove the large counterweight, which is attached with two long bolts.
We unscrew the bolts and remove the counterweight by lifting it up.
The counterweight is not light, so don't drop it or split it. By the way, it looks like a cast piece of cement mortar.
The body of the machine is connected to the drum by a rubber casing, which is attached to the drum by a large steel wire clamp. It is loosened by loosening the bolt.
Drum body without counterweight (top view).
Next, we put the car on its side and remove the bottom cover. It is made of plastic and is held by 4 self-tapping screws. Unscrew and remove.
A small counterweight, an electric motor and a pump are hidden behind the bottom cover, which are attached to the drum body. This whole structure rests on the body of the machine with two shock absorbers.
Next, we need to disconnect all cables from the contacts of the electric motor and pump.
In order not to get confused where which wire came up, you need to get in the habit of marking them. For this, a marker, a sketch is suitable, or you can take a photo of a contact group with wires.
Disconnect the two shock absorbers from the washer body, which are bolted down.

From the side of the top cover, a water inlet is connected to the body, we unscrew it without disconnecting the wires. (wires will not interfere with us).
From above, the drum body is supported by spring hangers. Using pliers, first disconnect the hooks from the drum body, and then from the machine body. We'll have to suffer a little, but everything will work out for sure!
In order to take out the drum, it is necessary to remove the front part of the washing machine. First, unscrew the control panel and then remove the front part with the door. All of them are fastened with self-tapping screws. The screwdriver did it in half a minute.
And here we have a disassembled car body. We unscrew the small counterweight to make it easier to remove the drum body.
DIY printer repair - what you can do at hometo save money on calling a master or sending a printing device to a service center? Not all problems can be solved on your own, but there are things that you can diagnose yourself. However, do not forget that a serious malfunction can be identified and corrected exclusively by the hands of a specialist with extensive experience and specialized tools for carrying out the corresponding work. Repair of printers by service center engineers YauzaOrgService guarantees high quality and speed of service delivery without overpayments. But what will it be possible to reveal at home?
• The most common cause of printer breakdown, whether Canon, HP, Epson, Oki, Samsung, Ricoh, Brother or Xerox, is to clean the machine irregularly. In simple words, it is dirt. It often leads to imbalance of the case, noise appears during operation, or paper picking stops. That is why it is recommended to clean the printing device at regular intervals and only when the equipment is off. But you need to know about the prohibition of the use of alcohol - for wiping we take only ordinary distilled water, a new sponge and cotton swabs.
• We check the correctness of operation: the printer must be plugged in, the tray is pushed in firmly to the very end, the sheet guides are set, the cartridges are correctly installed and there is no jam of foreign objects in the machine.
• Do not be afraid to inspect the inside of the equipment for paper debris or scraps, toner spills, plaster, sand, or water.
• Check the cartridge is full, if it has run out.
• If printer malfunctions are displayed as errors on the computer monitor, be sure to write down the code, number, or information on the screen for transmission to the wizard.
• Pay attention to the print quality of documents, whether there are additional streaks or spots, what color they are.
• Track the frequency of paper chewing.
• Listen for extraneous sounds, crackles, noises when printing.
Having considered all the above nuances, which often lead to the stoppage of the printer's functioning, you can speed up the process of correcting a malfunction, replace the repair procedure with preventive maintenance and save money on a specialist visit. Evaluation of the state of the equipment operability, the exact formulation of the problem and the listing of the problems that have appeared will allow the foreman to respond to the request as quickly as possible, since he will present the amount of work in advance. If this is not a serious breakdown and the situation allows you to repair parts, replace components or restore work quickly - printer repair can be carried out even at the diagnostic stage. By calling the phone number or sending an application through the website YauzaOrgService - assistance will be provided with the provision of a guarantee for all types of operations and services.
From time to time, printer owners encounter malfunctions. Most people have independently acquired personal experience in eliminating the minor flaws of such a device. As practice shows, a frequent reason for the unwillingness of the printer to work may be a software failure or a minor malfunction in the mechanical part, which can be eliminated independently, without seeking help from a specialist.
Let's consider the probable causes of malfunctions and how to eliminate them on our own, without resorting to the help of another person.
The device of printers such as HP, Canon, Epson, Samsung, Sharp, Ricoh is fundamentally the same. Therefore, we will consider several reasons that are found on all printing devices:
After the printer gave you the information about the error, first of all, check the presence of paper in the loading tray, whether the paper is jammed, the presence of toner in the cartridge, whether all the covers on the printer are well closed and, of course, the connection to the network and to the PC.
A common problem that you may not be shown is a software glitch.
One of the most common malfunctions is contamination of the mechanical parts of the device. First of all, you need to disconnect the printer from the power supply, open the top cover where the cartridge is located, take it out and visually inspect both the cartridge itself and the mechanisms in the field of view. In case of contamination of the mechanism, you just need to wipe it off with cotton napkins, slightly moistened with water. In hard-to-reach places, cotton swabs will come to the rescue.
Important! In no case should you use detergents and liquids containing alcohol.
In addition to all of the above, listen to the operation of your device. Are there any extraneous noises coming from it? If you hear them, this could be a signal that the gears that activate the printing mechanism are out of order. In most cases, they are made of plastic.
Below we will consider how to make repairs using the example of an HP LaserJet 1100 printer. This manual will also be useful for repairing Canon, Samsung and Epson printers.

flat thin screwdriver;
pliers with long jaws;
wet wipes or cotton-dampened pads.
Having prepared the necessary tool, we proceed to repair the device:
