LG washing machine does not turn on: reasons and solutions

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.

During the spin cycle the program freezes or the function does not work

The reasons for the lack of spin can be either mechanical or software at the level of control electronics. To exclude a breakdown at the electronics level, you need to run the spin function separately and see if fault codes appear on the control panel of the washing machine. If the machine has a touch control and a large screen, then a failure of the function will be accompanied by the symbols “ERROR”, followed by a digital error code. The analog control system is a little more complicated. It is represented by indicators that, when an error occurs, begin to glow or flicker.

One of the most common reasons for the failure of the spin function is the failure of the tachometer sensor or a break in the wires transmitting the control signal from the tachometer to the engine. In this case, DIY repairs seem to be quite problematic. Since it is necessary to have professional testing equipment.

Tachometer sensor

Mechanical causes of failure or poor performance of the spin function can be eliminated independently:

The belt transmitting torque from the motor to the drum has stretched. This problem occurs especially often in compact (narrow) washing machines.

Drive belt

Wear on engine brushes occurs during intensive use over a long period of time. At the same time, the washing machine works quite successfully at low speeds, but for spinning (maximum speed) the power is no longer enough.

Remove the electric motor

Remove the brushes

To replace the brushes, you need to remove the engine and find the brush holders on it (they may look different for different models), remove one of the brushes and purchase similar ones in the store. The need to replace brushes can be determined by the size of their protrusion from the brush holder. If at least one of them has less than 7 mm, then both cheeks need to be replaced.

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.

What should I check?

If the LG machine does not turn on, first of all you need to make sure of some points.

• The power cord is connected to the outlet. If it is indeed on, then it is worth checking the presence of electricity in general. If everything is in order here, you need to make sure that there is sufficient voltage in this particular outlet. Sometimes it happens that its level is not sufficient to activate the operation of the device. At the same time, the voltage in other outlets, even in the same room, may be normal. To make sure that the problem is really not in the washing machine, you should simply connect to the outlet any other device that can operate at a lower voltage.
• If the problem is not electrical, then you need to check the outlet itself. It should not be scorched, it should not smell like burning, it should not emit smoke.
• Now we inspect the power cord itself and its plug. There should be no damage or melting on them. The cord itself should be smooth, without creases or bends. It is very important that there are no wires sticking out of it, especially charred and exposed ones.

It is also necessary to carefully study the electronic display of the machine itself. It may well be that an error code will be displayed on it, which was the root cause of the fact that the device stopped turning on.

It is important to understand that if the device operates through an extension cord, then the problem may lie there . In order to determine whether this is actually the case, you need to check the integrity of its cord and socket, and also try to plug in another device through an extension cord.

If the check does not reveal any defects, then the reason really lies inside the automatic machine itself.

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.

Possible reasons for refusing to work

The very fact of a malfunction is determined very easily - the washing machine simply does not start working. The reasons for LG failure are not always related to the internal structure of the device. Very often they turn out to be external.

Reasons why the washing machine may not turn on:

1. No electricity supply to the device.
2. The washing machine power button is faulty.
3. Control module failure.
4. Damage to the electrical wiring inside the machine.
5. Interference filter functionality is impaired.
6. No door lock.

The simplest analysis and troubleshooting can be done independently. If the solution to the problem is not obvious, and there is no special knowledge on repairing electrical equipment, you may need the help of a specialist.

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.

A special case

In some situations, the automatic machine turns on normally and the washing process starts as usual. Only during operation can the device turn off completely, and then it can no longer be turned on. If this is exactly the case, you must do the following:

• unplug the machine from the outlet;
• check the level of its installation and the distribution of things in the drum;
• open the hatch door using the emergency cable, arrange the items evenly on the drum and remove some of them from the machine;
• close the hatch tightly and turn on the device again.

Such simple steps should help solve the problem that occurs due to improper installation of the device or its overload.

If they do not bring the desired result, and other methods of solving the problem do not help, you should contact the service center for specialist help. Trying to start the machine yourself in such cases is not recommended.

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.

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.

Removing the control panel block

Let's assume that everything is fine with the network cable. This means that the problem is hidden somewhere in the depths of the control unit. To continue testing, we need to dismantle this block and then disassemble it. Let's get to work.

1. First you need to remove the cover from the LG washing machine.
2. Next, you need to remove the powder receptacle and put it aside.
3. We take a Phillips screwdriver in our hands and unscrew the screws that are located next to the powder receptacle niche on the right and left.
4. Using the same screwdriver, we press in the latches of the control unit, and then carefully separate the unit from the body.

Be careful with the bundle of wires that connects the chassis to the control panel

We won't remove the wires for now. But if during the test you need to completely separate the control unit from the body, then first take a photograph of the location of the wires so that you can easily connect everything in place.

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.

How to repair?

The specific list of actions will depend on the exact reason for which the device failed.

So, if the lock on the machine door stops working or the handle on it breaks, you will need to completely replace these parts . To do this, you need to purchase a new locking element and handle from the same manufacturer and designed specifically for this model of machine.

In addition, a breakdown of the surge protector may also be the reason why the washing machine stops turning on.

This device is designed to protect the device from combustion. Voltage surges, frequent switching on and off of power negatively affect the operation of the device. It is network filters that are designed to eliminate these consequences.

However, if power outages occur too often, they themselves can burn out or short out, which means completely paralyzing the operation of the machine. In this case, you need to do this:

• find the filter - it is located under the top cover of the housing;
• using a multimeter, you need to determine how it reacts to incoming and outgoing voltages;
• If in the first case the filter works normally, but does not catch the outgoing voltage, it must be replaced.

If the machine does not turn on for other reasons, you need to do something a little differently.

• Check whether the automatic safety interlock device has tripped. Today it is installed by default on all automatic washing machines from this manufacturer. It is triggered in cases where the device is energized, that is, it is not grounded. In such cases, the machine is disconnected from the network and its grounding is checked and, if necessary, corrected.
• If all the indicators or only one are on, and no error code is displayed on the electronic display, you should check that the “Start” button is working properly. It is quite possible that it was simply disconnected from the chips or simply stuck. In this case, the device should be de-energized, the button should be removed from the machine body, the contacts on the microcircuit should be cleaned and installed in place. If there is any damage to the button, it should be replaced with a new one.
• A malfunction of the control unit may also be the reason why the automatic machine does not turn on. In this case, the module must be removed from the housing, its integrity checked and, if possible, taken to a diagnostic center for replacement.

All these methods of solving the problem help in situations where the machine does not turn on to work at all. In addition, they require the use of special tools and skills in handling them.

If there are none, then it is better to entrust the repair work to a specialist.

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.

Prevention of breakdowns

To ensure that the machine works properly and that problems with switching on do not bother you, follow these simple recommendations:

• Before using any device, carefully read the operating instructions and manufacturer's advice.
• Give the unit a rest. Are you planning 2-3 washes in one day? Wash with a break of 2-3 hours between uses. Otherwise, the device will work at the limit of its capabilities and will quickly fail.
• After each wash, wipe the body, tank, detergent tray, rubber seals and other parts dry to prevent the appearance of mold.
• Visually inspect equipment and its main parts regularly.
• Do not neglect anti-scale prevention: run the wash without laundry, at high temperatures, with the addition of special cleaning agents (or regular citric acid).
• Use high-quality washing powders, gels and shampoos from well-known manufacturers.

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.

Knocking and rattling noise when the LG washing machine is running

If you hear loud knocking, grinding, or rattling noises when the drum rotates, the reason may be that there is not enough laundry. Just put more stuff in the drum.

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.
