LG direct drive washing machines are in demand among buyers. The new design allowed to significantly increase the engine resource, while the SM belongs to the affordable price segment.
But such equipment is also subject to breakdowns, and servicing LG washing machines in a service center can sometimes be expensive. Therefore, we will tell you about typical malfunctions of this brand and the possibilities of self-repair.
Main malfunctions of LG washing machines
According to statistics, damage to direct-drive LJ washing machines occurs after five years of operation. To understand where to start troubleshooting, let’s analyze how direct-drive SM and a standard machine work.
Look at the diagram of the LG washing machine:
In the first case, rotation of the drum with a drive belt is provided. In the second - the drum rotates the engine directly. Such a motor also does not have brushes that constantly wear out. In the event of a breakdown, you immediately determine that the cause is in the motor, and not the parts adjacent to it.
We examined the principle of work, now we will consider which nodes most often fail:
- Element of heating (TEN). You notice that washing takes place in cold water, the powder does not dissolve well and leaves streaks on clothes. You can verify the malfunction of the heater by measuring its resistance with a tester.
- Failure of the pressure switch. The pressure sensor monitors the amount of water in the tank: when it breaks, you may notice a constant drain, or the system signals a water overflow. Repair and replacement of the sensor can be done by yourself.
- Bearings and oil seals. When the driving elements are worn, you will hear a roar, noise during the operation of the washing machine. It’s easy to find out about it on your own: spin the drum by hand, if a rattle is heard, it means the bearings.
- Electronics often suffers from power surges. The main module rarely breaks down, more often wires and terminals burn out.
- Drain pump. Its design in LG SMA is such that the drain system is often clogged. Therefore, if you notice that the washer does not drain water well, check the pump.
- Inlet valve problems also arise. It is quite possible to repair the ElGi washing machine yourself by replacing this element.
AlJ washing machine trouble codes
How can the user understand exactly where the LG washing machine broke? There is a self-diagnosis system for this. When a problem is detected, the system displays the error codes of AlGi on the display.
All you have to do is decrypt the code and find the problem.
Malfunction code | Value |
Ae | Auto power off error. There was a leak. Aquastop worked. |
CE | SM overloaded. |
dE | The hatch is not completely closed. The wash does not start. |
FE | Exceeded the water norm in the tank. |
E1 | Water fell into the pan. Check for leaks. |
HE | Damage to the heating element (TENA). |
IE | No gulf of water for 4 minutes. |
OE | No draining of water for 5 minutes. |
PE | Water did not reach the indicated level within 25 minutes. |
UE | An imbalance has arisen. |
tE | Damage to the temperature sensor. |
E3 | Invalid loading. |
SE | Failure of the tachogenerator. |
LE | Damage to the door lock (UBL). |
Now you know the meaning of the errors and you can start repairing the automatic machine with your own hands. Consider typical malfunctions that may occur during the operation of the LG washing machine.
LG does not turn on
For what reasons the washing machine may not turn on, how to fix the malfunction of the washing machine?
- Check if the sunroof is securely closed. Press it tightly - until it clicks.
- Check the power outlet - the mains voltage may be too low. To do this, connect another household appliance to it: if it works, then the reason is not on the network.
- Inspect the washer cable and plug for damage. Perhaps you need to isolate the defective areas, but it is better to replace the power cord.
- Turn the inlet valve. If the water is shut off, the washing process cannot begin.
- Lastly, the SMA wiring is inspected. To do this, remove the top panel of the machine by unscrewing the two screws on the back. Inspect the interference filter and its wiring at the time of the malfunction.
How to replace a surge protector
- Unplugging the washer from the network and removing the top cover, you will see a filter at the top.
- Remove the screws that secure the filter on the rear panel.
- Pick up a new part and alternately switch the wires from the faulty filter to a new one.
- Then fasten it to the body with bolts.
Now you know how you can repair your LG washing machine with your own hands if a wiring breakdown occurs.
The water draws normally, but the wash does not start
You turned on the AGR, the water was taken, but the washing never starts. What is the reason?
- Defective heater (heater). Water does not heat up, so washing does not start. If you need to urgently wash your laundry, try choosing a washing mode without heating. The video will help you in replacing the item:
- Damage to the pressure switch or thermistor. A faulty pressure switch does not signal that the optimum water level in the tank has been reached. If the thermistor fails, the module does not receive a message about the heating temperature. Need replacement items.
- The main module of the LG washing machine, which instructs the machine components to start work, is out of order.
- Malfunction of the engine of the LG washing machine with direct drive.
Water does not flow into the tank of the LG machine or flows too slowly
How to repair a washing machine yourself:
- Unscrew the shutoff valve at full capacity. Perhaps it was blocked or not fully open.
- Inspect the intake hose. He could bend over or clog.
- Filter mesh clogged with garbage. It is located between the inlet hose and the valve - remove and clean.
- There is a malfunction in the water supply valve. To inspect and replace it, you need to remove the top cover - the valve is located on top of the wall. You need to ring his contacts with a multimeter, and also check the membrane, which could wear out. In the event of a malfunction, a new part is installed.
- If the pressure switch is broken, you can perform an independent repair of the LG washing machine.
How to replace the pressure switch
- After disconnecting the SM, remove the top panel by unscrewing the mounting bolts.
- Disconnect the connectors from the pressure switch, unscrew the screws that secure it to the housing.
- Take out the level sensor, disconnect a hose.
- Install the new part in the reverse order.
Knocking and crashing while the LG washer is working
If you hear loud knocks, rattle, or rattle when you rotate the drum, the cause may be an insufficient amount of laundry. Just load more stuff into the drum.
The drain in the LG car does not work
The reasons:
- Incorrect mode selection.
- Blockage in the drain system (filter, nozzle, pump).
How to fix the malfunctions of the Lji washing machine with your own hands? 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 it.

Door does not open
A similar malfunction can occur if water is not completely poured out of the tank. To open it, you must manually remove the remaining water through the drain filter.
Maybe the program is not over yet and the drum rotates, so the hatch does not open. Wait until the cycle ends.
