The main thing is to be patient, free time, the necessary set of tools and to delve into the detailed instructions on the repair steps that we will provide you. So, how to replace the elements in the LG washer, and what “pitfalls” you may encounter at the same time, we will describe further.

We will collect materials and tools

Proper preparation for the repair will save time and nerves on the upcoming work. To change the drum bearings in the LG washing machine, you need a whole set of tools. At your fingertips you should have the following inventory:

  • a pair of screwdrivers (slotted and Phillips);
  • pliers;
  • a hammer with a bronze striker;
  • set of open-end wrenches;
  • set of socket heads;
  • metal rod;
  • aerosol grease WD-40;
  • silicone sealant;
  • special grease for stuffing box and tools for cars LG

Having figured out that all the required tools are available, you need to purchase replacement parts. When selecting components, be sure to pay attention not only to the model of the washing machine, also specify the size of the stuffing box, type of bearings. The necessary data on the details can be found in the technical data sheet of the equipment.

When buying parts in a specialized store, consult a consultant for help. What is the serial number of the washer, data on accessories. A specialist will help you choose the right bearings and packing.

It’s best to visit a store with parts to be replaced already removed from the washer case, so the likelihood of buying “wrong” will be reduced to zero.

Do not purchase spare parts not intended for this category of equipment. In this case, the risk is great that after some time after installation, the repair will have to be repeated again. As for the cost, the original bearings will cost about 350 rubles, the o-ring - about 300 rubles.

After a set of tools and parts for replacement is prepared, you should take care of the workplace. To disassemble the machine in a cramped bathroom does not work, the ideal option is to move the device to the garage or, at worst, a spacious room. If DIY repair is done in the apartment, take care of the safety of the flooring - pre-lay it.

It is important to free up as much space as possible so that nothing would interfere with disassembling the washing machine and changing accessories.

Tank extraction

The first step, if necessary, the replacement of bearings and stuffing box will be disassembly of the washer. To remove the tank, you have to remove the top cover and the front wall of the machine, remove other elements of the system from the housing. The upcoming action algorithm will be as follows:

  • unscrew the 2 bolts holding the upper case cover, remove it and put it to the side;
  • remove the detergent dispenser. You can immediately clear it of plaque and debris;
  • unscrew all the fastening mechanisms that support the control panel of the machine;
  • carefully, trying not to damage and tear off the wires, put the panel on top of the washer;
  • remove the lower false panel of the case, for this purpose it is necessary to bend, using a screwdriver, special latches;
  • loosen the metal collar encircling the cuff of the tank, remove the ring to the outside;
  • disconnect the contacts of the sunroof locking device and remove the sensor;
  • Next, unscrew the bolts holding the front wall of the housing. Look for self-tapping screws behind the drain valve, cuvette, on the right and left at the top of the body, at the bottom right and behind the dashboard. Now remove the front wall of the washing machine is not difficult.remove the tank from the machine LG

The case is almost complete, access to the tank is obtained. Next, you need to disconnect the wiring connecting the tank with other elements of the washer, remove the fasteners. This is about:

  • fastening of the bulk valve;
  • discharge pipe;
  • wires leading to the heater;
  • motor wiring;
  • cables of the pump picking up water;
  • counterweight mounts;
  • branch pipe pressostat;
  • shock absorbing elements.

When everything that is possible is disconnected from the tank, it is necessary to remove it from the housing. An assistant should be called here. The first person must press the springs, the second - to pull out the part. If you try hard, then you can cope with the task and alone.

Tank disassembly procedure

The tank of the washing machine is two fastened parts. To disconnect the halves, you must remove all the bolts and release the special fasteners.

If any fasteners cannot be removed, they can be treated with WD-40 aerosol grease.

When the main fixing screw is unscrewed, it is necessary to remove the drum pulley and return the bolt to its original place. After that, put the prepared metal rod on the bolt and start gently hammering it to break the shaft. It is important not to damage the shaft, otherwise the repair with your own hands will result in significant costs.

Change damaged parts

After the tank is disassembled into two halves, you can proceed to removing worn-out components and installing new parts. Further work will occur precisely with the rear half of the drum device. In the middle you will see a sealing ring, in other words - an epiploon. Use a screwdriver to remove it from the seat.

Bearings will have to be knocked out using the same metal rod. The end of the rod is placed on the edge of the bearing, and is tapped with a hammer. The action must be performed several times, around the entire circumference of the part, until the elements are removed.

To minimize the risk of damage to the mechanism, you can use a special puller, but this will increase the cost of repair work.

The opening should be well cleaned from metal chips, a layer of oil and other dirt. It is important to put new bearings and stuffing box in a prepared, clean place.

Now you should take new components and prepare them for installation. Do not forget about the special grease, which should be treated with the landing area. The bearings are driven into the old place. To properly install the gland, coat it with a good layer of lubricant. Such a measure will prevent water from entering the bearings.The process of replacing bearings on a LG washer

The shaft of the washing machine can also be greased. The main thing is not to forget in this case, to run the machine a couple of times in the “idle”, to prevent contamination of the laundry. Further assembly of the tank and the washer takes place in the reverse order.

Connecting the halves of the tank, you should use a moisture-proof sealant for more reliable fastening of the structure. When the equipment is fully assembled, check the operability of the washer. Plug in the machine and start the “idle” wash cycle (without putting things in the drum).

What problems can arise?

If you are engaged in disassembling and repairing a machine for the first time, there is a risk of some errors during the work. So that an unfortunate oversight does not lead to a malfunction of the unit and an increase in the cost of repairs, it is better to familiarize yourself with the most common mistakes made by beginners in advance.

  • The wiring of the hatch lock device simply breaks when the front wall is inaccurately removed.
  • The cuff of the door becomes unusable due to its “pulling” out of the case with great force, with a metal collar not pulled out.
  • The tank pulley is damaged when carelessly removing it from the axle.
  • Fasteners that are not pre-treated with WD-40 grease deteriorate, but are removed by the craftsmen with great effort.
  • The wires leading to the temperature sensor come off.
  • The water supply pipe breaks out, along with the inlet hose.
  • The drum is damaged when the bearings are carelessly knocked out. As a result, you have to change the drum completely, and this is several times more expensive repair.

Before embarking on a replacement, think carefully about whether you can afford such a job. If you are not sure that you can handle it purely, it is better to trust a professional master. In this case, the specialist will have to pay from services 4,500 rubles, but you will receive a guarantee for the repair. The final cost depends on the model of equipment, type of tank (it is collapsible or cast), the price of spare parts, the complexity of the upcoming work, their urgency, etc.
