LG washing machine turns off during washing

It's quite rare for an LG automatic washing machine to shut off during a wash cycle. This could be caused by a simple, short-term malfunction, or by a failure of a system component. First, restart the machine by unplugging it for a few seconds, then plugging it back in. If this doesn't work, and the LG washing machine continues to shut off during a wash cycle, a detailed diagnosis will be necessary.

What could have happened?

There are many factors that can cause an LG washing machine to shut off spontaneously. To understand how to resolve the problem, it's necessary to diagnose the malfunction. The most likely cause is:

• failure in the set washing mode (indicates a problem with the control module);
• exceeding the permissible loading weight (the electric motor power is not sufficient to rotate the excessively heavy drum);
• choosing the wrong washing mode;
• A broken door locking device. In this case, the washing machine will not operate because the loading door will not close properly;
• A safety shutdown triggered by the leak protection system. The water level sensor in the tray triggers a signal, causing the appliance to stop working;
• malfunction of one of the most important elements of the machine: heating element, motor, drain pump, etc.;
• blockage of the water intake or drainage system.

Most problems can be easily fixed by yourself. It is necessary to assess the condition of the washing machine and observe at what stage of the program the appliance stops functioning. Determining the root cause of the malfunction will help restore the washing machine to full functionality.

An imbalance has arisen

Modern LG washing machines are equipped with a convenient sensor that measures the weight of the laundry being loaded into the drum. If the manufacturer's permitted weight is exceeded, the machine will display an error code or simply shut off.

Additionally, when filling the drum with items, distribute the clothes evenly across the interior. Otherwise, the laundry will form a solid lump, which will, in turn, cause the drum to become unbalanced and the washer to shut off.

In addition to the resulting imbalance, overloading the machine can lead to the failure of the shock absorbers and stretching of the springs that hold the drum.

This is why it is necessary to adhere to the maximum load weight of the washing machine and correctly arrange the laundry inside the drum.

Short circuit to one of the nodes

LG washing machines often shut off spontaneously due to an unexpected failure of a critical component in the system. For example, if the heating element fails, the water drawn into the tank will not heat up according to the set parameters, but will be either cold or boiling. If overheating is detected, the temperature sensor will automatically activate and shut down the machine.

If the electric motor is damaged, the washing machine will run uncontrollably. In this case, you may notice the drum spinning too fast or too slowly. A faulty drain pump is easily identified when the waste liquid is draining into the sewer.

If water drains from the tank for more than 10 minutes, it could indicate a clogged pump, drain hose, or a permanent pump failure.

Aquastop activation

An LG washing machine equipped with a leak protection system may shut off when the water level sensor located in the washing machine's tray is triggered. In this situation, the washing machine should display an error code on the screen before shutting off, but unfortunately, the machine doesn't always notify users of this. Therefore, users may see their LG washing machine turned off, with no error code on the display. At first glance, it's impossible to tell that the washing machine's tray is full of water.

Sometimes the leak prevention sensor starts to stick and trigger at any time. In this case, repairing it is quite simple: simply reach into the sump and return the float to its original position.

Control module failure

The main control unit can trip the circuit breaker. Testing the circuit board without disassembling the machine and opening the module is impossible, and that would require considerable work. Only an experienced specialist with knowledge of this field can professionally test the control unit and carry out its repair.

When performing a cursory diagnosis yourself, it's best to use a multimeter. Based on the data it provides, you can determine the board's health. Sometimes, just looking at the module is enough to tell that it needs replacing. The unit will show burnt contacts, scorched tracks, and other signs of damage.
