Reasons why the LG washing machine does not turn on

Housewives quite often have an annoying situation - the washing machine does not turn on. As a rule, the problem appears unexpectedly. Before the next wash, you add powder, put the laundry in the tank and try to start the equipment, but the machine does not react in any way to repeated attempts to turn it on.

The washing machine does not turn on for various reasons: these can range from minor malfunctions to serious problems

Before you run to the nearest service center or write off your assistant, you can try to find the reasons that caused the equipment to fail.

In the event of a breakdown, contact the HelpMasterService workshop. Repair of any complexity of all brands of washing machines.

Basic malfunctions of LG washing machines

According to statistics, breakdowns of LG direct drive washing machines occur after five years of operation. To understand where to start troubleshooting, let’s look at how a direct-drive SM and a standard machine work.

Look at the diagram of the LG washing machine:

In the first case, the drum is rotated using a drive belt. In the second, the drum rotates the motor directly. This motor also does not have brushes, which constantly wear out. If there is a breakdown, you will immediately determine that the cause is in the motor, and not in the parts adjacent to it.

We have analyzed the principle of operation, now we will look at which nodes most often fail:

• Heating element (heating element). You notice that washing is done in cold water, the powder does not dissolve well and leaves streaks on clothes. You can verify that the heating element is faulty by measuring its resistance with a tester.
• Failure of the pressure switch. A pressure sensor monitors the amount of water in the tank: when it breaks, you may notice constant self-draining, or the system signals an overflow of water. You can repair and replace the sensor yourself.
• Bearings and seals. When the moving elements wear out, you will hear a rumble and noise when the washing machine operates. It’s easy to find out about this yourself: rotate the drum by hand, if you hear a grinding noise, it means the problem is in the bearings.
• Electronics often suffer from voltage surges. The main module rarely breaks down; wires and terminals burn out more often.
• Drain pump. Its design in the LG SMA is such that the drain system often becomes clogged. Therefore, if you notice that the washer is not draining water well, you need to check the pump.
• Problems with the inlet valve also occur. It is quite possible to repair the ElG washing machine yourself by replacing this element.

Troubleshooting

Understanding that your refrigerator is not working correctly is simple: you just need to listen carefully to it. If during operation it starts to hum, and after a few minutes it stops, then something has gone wrong. It’s even worse if the unit turns off on its own: in this case, it should be disconnected from the power supply before the cause of the breakdown is determined and eliminated.

One of the most common (and simplest) situations is the failure of the control relay. Replacing it will cost you relatively little, and the refrigerator will work like a clock again. A more complex (and expensive) problem is repairing the electronic unit. But replacing the compressor will cost the most.

You can understand that the problem is in the compressor if you measure the resistance of its windings. To determine whether the control relay has failed, it will have to be disassembled. Or you can simply replace the old relay with a new one - and the problem will be solved. But if, nevertheless, repairs are required, check the condition of the solenoid core - it fails quite often. Instead, you can install a piece of metal wire, and for some models, as an emergency temporary measure, even a refill from a regular fountain pen will do - then you will be able to find a little time to carry out a full repair.

Speaking about modern models, it is worth noting their silent operation. On the one hand, this is good - we can not pay attention to turning the unit on and off. But on the other hand, without hearing the nature of the operating cycles, we will notice the malfunction that has appeared only when the refrigerator completely stops performing its function - generating cold.

Be attentive to your equipment, carry out routine repairs on time, and it will serve faithfully for many years.

Fault codes for the ElG washing machine

How can the user understand where exactly the LG washing machine broke down? There is a self-diagnosis system for this. If a problem is detected, the system displays ELG error codes on the display.

All you have to do is decipher the code and find the problem.

Now you know the meaning of errors and you can start repairing the automatic machine yourself. Let's look at typical malfunctions that can happen during operation of an LG washing machine.

LG machine won't turn on

For what reasons may the washing machine not turn on, how to troubleshoot a washing machine?

1. Check that the hatch door is securely closed. Press it tightly until it clicks.
2. Check the outlet - the voltage may be too low. To do this, connect another household appliance to it: if it works, then the problem is not in the network.
3. Inspect the washer cable and plug for damage. It may be necessary to isolate the defective areas, or better yet, replace the power cord.
4. Turn the inlet valve. If the water is turned off, the washing process cannot begin.
5. Lastly, the MCA wiring is inspected. To do this, remove the top panel of the machine by unscrewing the two screws at the back. Inspect the interference filter and its wiring at the time of the problem.

How to replace a surge protector

• After unplugging the washing machine and removing the top cover, you will see a filter at the top.
• Unscrew the filter mounting screws on the rear panel.
• Pick up the new part and alternately switch the wires from the faulty filter to the new one.
• Then secure it to the body with bolts.

Now you know how you can repair an LG washing machine with your own hands if the wiring breaks down.

The water fills normally, but the wash does not start

You turned on the SMA, water was drawn in, but the washing still does not start. What is the reason?

1. The heater (heating element) is faulty. The water does not heat up, so the wash does not start. If you need to wash your clothes urgently, try choosing a low-heat wash cycle. This video will help you replace the element:

1. Failure of the pressure switch or thermistor. A faulty pressure switch does not signal that the optimal water level in the tank has been reached. If the thermistor fails, the module does not receive a message about the heating temperature. Elements need to be replaced.
2. The main module of the LG washing machine, which gives the machine components the command to start working, has failed.
3. LG direct drive washing machine motor malfunction.

For more information about the repair, watch the video:

1. Incorrect mode selection.
2. There is a blockage in the drain system (filter, pipe, pump).

How to fix problems with a Lji washing machine with your own hands? You need to check the drain pump. For this:

• Open the hatch and remove the clamp by bending the cuff to the side.
• Disconnect the door lock connectors and close the door.
• Remove water using a drain filter.
• After unscrewing the mounting bolts, remove the filter housing.
• Lift the top panel by removing the screws.
• Remove the dispenser tray.
• Unscrew the bolts behind the tray at the front and back.
• Remove the control panel by unfastening the latches.
• Remove the front panel screws. Take it away.
• Loosen the clamps of the circulation and drain hoses. Remove the hoses.
• Disconnect the pump hose clamps by loosening them.
• Remove the pump assembly bolts.
• Unclench the clamps and remove the pump.
• After unscrewing the screws, pull the pump out of the volute.
• Look for threads on the impeller that could interfere with operation.
• If there is a malfunction, install a new part.

How to check?

Determining problems with the control module is not that difficult.

There may be several signs that the control board needs repair, namely:

• The machine, when filled with water, immediately drains it;
• the device does not turn on, an error is displayed on the screen;
• on some models the panel LEDs flicker or, conversely, light up simultaneously;
• programs may not work properly, sometimes failures occur in executing commands when pressing touch buttons on the machine display;
• the water does not heat up or overheats;
• unpredictable engine operating modes: the drum either spins very slowly, or picks up maximum speed.

To carry out an inspection to identify a breakdown in the “brains” of the SMA, you need to remove the part and carefully examine it for burns, damage and oxidation, for which you will need to manually remove the board as follows:

• disconnect the unit from the power supply;
• shut off the water supply;
• remove the cover by unscrewing the screws at the back;
• pressing the central stop, pull out the powder dispenser;
• Unscrew the screws around the perimeter of the control panel, lift up and remove;
• disable chips;
• Unfasten the latch and remove the unit cover.

The door does not open

A similar malfunction can occur if the water is not completely drained from the tank. To open it, you need to manually remove any remaining water through the drain filter.

Perhaps the program is not finished yet and the drum is rotating, so the hatch does not open. Wait until the cycle ends.

A malfunction can be called a broken door lock - UBL. LG washing machine door repair can be done at home.

A video on the topic will help you:

Checking and replacing the pressure switch

If the display shows error codes FE, IE or PE, you should pay attention to the water level sensor in the tank. To get to it, remove the top cover of the machine. On one of the side panels you will see a round-shaped device, to which a hose from the tank and wires with a connector are connected.

To check the functionality of the part, disconnect the clamp and remove the hose coming from the tank. It happens that the hose becomes clogged with lint, threads, dirt and other small objects. If a blockage is found, clean the hose. Then, instead, connect a hose of the same diameter, 30–40 cm long, to the pressure switch. Blow into it, building up pressure. If you hear the relay click, the device is working properly. Connect the cleaned hose from the tank to it and check the operation of the CM. Replacing a non-working sensor is also not difficult - just remove the old device, disconnecting the hose and connector with wires from it, and then install a new pressure switch in its place.

Diagnosis and replacement of the fill valve

If the MCA inlet valve is leaking water all the time (IE error), you can replace it yourself. To do this, follow these steps:

1. Turn off the water supply valve to the inlet hose and expand the CM.
2. Unscrew the inlet hose from the valve fitting.
3. Use pliers to remove the strainer from the fitting and check it for clogging. If necessary, clean under running water.
4. Remove the top cover of the SMA, then disconnect the pipes from the valve.
5. Unscrew the fasteners holding the valve and disconnect the wire terminals.
6. Use a multimeter to check the serviceability of the valve control coil. Its resistance should be in the range of 2.5–4 kOhm. If a break is found, the valve will have to be replaced completely.
7. If the control coil is working properly, all that remains is to replace the rubber cuffs in the valve - most likely they are leaking water due to wear.

Checking and replacing the drain pump

The appearance of the OE error code on the display indicates a problem with draining the liquid from the tank. To find out the cause of the problem, you need to check the drain filter - it may be clogged. First drain the water from the tank. If the filter is clogged with debris, clean it and reinstall it, then check to see if the drain works.

If the filter is clean, but the pump still does not pump out water, you will have to replace it. For this:

• turn off the power to the machine;
• carefully place the equipment on the left side panel;
• remove the faulty pump and install a new part.

In conclusion, it can be noted that the listed malfunctions of LG washing machines can be easily fixed on your own. But it is better to entrust the search for damage in the control unit and replacement of bearings to an experienced technician. To purchase new replacement parts, you need to know the model number of your SMA. It is indicated in the accompanying documentation and on the equipment body.

Call the master

Many users find it difficult to figure out Samsung devices and repairs on their own. To solve the problem, it is advisable to invite a specialist. He will conduct a full diagnostic of the device and identify the real cause of the problem.

Home repairs often result in the need for repeated intervention in the design of the washing machine. This is fraught with additional financial expenses.

You can find a responsible technician in service centers that service household appliances. Specialists have the ability to perform professional diagnostics using instruments.

The repair technology has been worked out in such workshops down to the smallest detail. Our craftsmen use proven products and high-quality components. The cost of repairing a Samsung if there is a problem with filling the tank depends on the cause of the breakdown.

The workshop price includes the following rates:

• replacement of the water supply valve – from 1100 rubles;
• flashing or replacing the control board – from 1,500 rubles;
• replacement of a water level sensor – from 1300 rubles;
• reinstallation of the door locking device – from 1500 rubles.

You can also find a person who does private repairs of washing machines at home. However, responding to such advertisements sometimes ends in new problems.

Private craftsmen do not provide a documented guarantee for their work and often inflate the price. A verbal agreement may not end in favor of the equipment owner. Therefore, contacting official workshops is more profitable from both a technical and economic point of view.

Fresh lemon is not only suitable for tea: clean dirt from the surface of an acrylic bath by rubbing with half a cut citrus, or quickly wash the microwave by placing a container of water and lemon slices in it for 8-10 minutes at maximum power. The softened dirt can simply be wiped off with a sponge.

If your favorite things show the first signs of gestation in the form of untidy pellets, you can get rid of them using a special machine - a shaver. It quickly and effectively shaves off clumps of fabric fibers and returns things to their proper appearance.

Threads made of gold and silver, which were used to embroider clothes in the old days, are called gimp. To obtain them, the metal wire was pulled for a long time with pliers to the required fineness. This is where the expression “to drag out the rigmarole” came from - “to do long, monotonous work” or “to delay the completion of a task.”

The dishwasher cleans more than just plates and cups. You can load it with plastic toys, glass lamp shades and even dirty vegetables, such as potatoes, but only without using detergents.

The habit of using an automatic washing machine “sparingly” can lead to the appearance of an unpleasant odor in it. Washing at temperatures below 60℃ and short rinses allow fungi and bacteria from dirty clothes to remain on internal surfaces and actively multiply.

Stretch ceilings made of PVC film can withstand from 70 to 120 liters of water per 1 m2 of their area (depending on the size of the ceiling, the degree of its tension and the quality of the film). So you don’t have to worry about leaks from neighbors above.

Why doesn't it turn on?

Having plugged the plug into the socket, you discovered that your washing machine did not respond, the indicator light did not light up, and the welcome music did not play. There are many reasons why a washing machine does not turn on: from simple carelessness of the user to serious breakdowns. Some of them can be fixed on your own, while others can only be fixed with the help of a specialist.

Lack of electricity

The most common situation due to which the unit may not start is the lack of electricity in the network. The following events may be the reason for this:

1. The electricity in the house was turned off, but you didn’t notice it.
2. The machine was knocked out due to an overload in the network or a short circuit.
3. An RCD has tripped, for example, due to a power leak.
4. The socket has failed. To eliminate this assumption, plug in another device. If it works, then this reason can be immediately discarded.

The network cable is faulty

To check the working condition of the power cord running from the equipment to the outlet, it is best to use a tester (multimeter). Similar manipulations can be performed using an indicator screwdriver. If the problem is confirmed, then the cord must be replaced completely. Or, having discovered the location of the break, try to connect it using special electrical tape or a soldering iron, which is actually wrong and dangerous, and will not solve the problem, but will only delay it.

The power button is faulty

In most washing machines, after plugging them into the outlet, power is supplied to the off/on button. You can check the working condition of the button using a tester. Having set it to buzzer mode and turned off the power to the machine, you need to ring the button in the on and off state. If it is working, the multimeter will make a characteristic sound. Otherwise, it will need to be replaced.

Problem with FPS (interference filter)

The interference filter suppresses electromagnetic waves that can interfere with the operation of other nearby devices. This could be a TV, dishwasher, microwave oven. If the interference filter breaks down, it stops passing electric current through the circuit, resulting in a problem with turning on the washing machine.

To make sure that the FPS is working properly, you need to test it with a multimeter.

To do this, you need to remove the top cover of the washing machine and find the interference filter underneath. At the input of the FPS there are three wires - grounding (or earth), phase and zero (neutral); There are only two outputs - phase and neutral. If there is voltage at the input, but there is no voltage at the output, then the problem is in this part and it needs to be replaced.

Attention! When ringing the interference filter, be extremely careful.

The control module has failed

If the reasons given are not confirmed, then the problem lies in a non-working control module. Keep in mind that replacing this part is a very expensive investment in the future of the washing machine, and is not always justified. But experienced specialists in some cases can repair this part; all that remains is to call a specialist to your home.

Possible actions and repairs

High-tech and structurally complex equipment requires detailed diagnostics, some knowledge and special tools. Therefore, an adequate assessment of your capabilities is the first mandatory point before any manipulation with such equipment.

The locking device needs to be replaced

The reason for its failure may be a long service life. The reason is the deformation of the bimetallic plate due to a constant temperature difference. Replacing an element requires disassembling the locking device (UBL).

1. Unscrew the two screws securing the lock to the body. The element is removed by supporting it with your hand from the back.
2. The wires with connectors are disconnected from the faulty part, then they are connected to a new spare part. It is again fixed in its rightful place with screws, the cuff is returned to its previous position, and secured with a clamp.
3. They check the performance of the machine and do a test wash.

Testing and repair of the command device

If the results of checking the remaining nodes are zero, then there is only one potential culprit left - the programmer (command device). In this case, quite painstaking and careful work remains. The unit is disassembled into small parts, then the “patient” is examined.

• to gain access to the command device, first disassemble and remove the front panel of the washing machine;
• remove the electronic module and begin disassembling it;
• remove the cover by pressing the latches located on the sides;
• remove the board, inspect it for burning, if there are such places, solder them;
• The resistance at the contacts is tested with a multimeter;
• check (clean) the central gear, then all elements, including the core, are removed;
• test the electric motor winding, replace the wire if burns are detected;
• the parts are treated with alcohol and placed back, observing the reverse assembly order.

Not all washing machine models have relatively simple programmers; some are quite complex. In this case, no one can guarantee a successful repair, so it is more logical to replace the unit with a new module.

New cars - problems with the button

The latest generations of washing units are capable of presenting another “surprise”. This is a problem with the “Start” button, since the current supply to it comes directly from the power cord. To check the potential source of problems, do the following:

• disconnect equipment from the network;
• remove the upper part of the body;
• dismantle the control panel;
• disconnect the wires from the button;
• connect the multimeter, plug the device into the network;
• test the presence of current when in the on position.

If the button functions normally, then the search for the culprit devices continues. Otherwise, the faulty part is replaced. Some washing machines have a different operating principle, where the voltage is supplied to the electronic module/programmer. It all depends on the manufacturer and the specific model.

Why does the washing mode not start?

There are also cases when, when the device is turned on, the indicator lights up, but the washing does not start. If, when turned on, the washing machine informed you that it is working with a lighted indicator or a sound signal, but when you select any mode, the washing does not start, then the problem lies in something below.

Door lock faulty

The first thing to do is to make sure that the hatch is really tightly closed. If nothing interferes with the door and it is closed, you need to check whether the hatch was locked after the program was started. If blocking does not occur, this indicates that the door lock is faulty. To be completely sure of this, you need to ring the mechanism.

If, when the program starts, voltage is supplied to the door, but blocking still does not occur, then the UBL (hatch locking device) is faulty and must be replaced.

Indicators flash when turned on

If, after connecting the equipment to the network, you notice that all the indicators are blinking in a chaotic manner or go out and light up in the same way, then the problem lies in the wiring. In this case, you need to find the problem area and replace it.

Possible reasons

It is very easy to determine a malfunction such as a machine not turning on: it does not work at all, and when it is turned on, the display does not light up at all, or one indicator or all of them light up at once.

There are several reasons for this problem.

• The Start button is faulty. This could be due to it being sunken or stuck. Also, the contacts could simply come off.
• Lack of electricity. This can happen for two reasons: the automatic washing machine is simply not connected to the network or there is simply no electricity.
• The power cord or the outlet itself that it connects to is damaged or faulty.
• The noise filter could be damaged or even burnt out.
• The control module has become unusable.
• The wires of the electrical circuit itself are burnt out or poorly connected to each other.
• The washing machine door lock does not work.

As you can see, there are several reasons why the washing machine does not start. However, even when it stops working, there is no need to panic. You just need to determine the exact cause of the problem and find out how to eliminate it.
