12 error codes for LG washing machines and how to fix them

You are trying to start a program, but your LG washing machine shows a PE error on the display and refuses to wash. Perhaps the PE error first appeared during the washing, rinsing or spinning process, and now it occurs constantly.

On LG models without a screen, this error is reported by the wash, rinse and spin indicators - they all light up or flash at the same time .

PE error - in what cases can you fix it yourself?

• If the error occurs for the first time, try unplugging the machine from the power supply for 10 - 15 minutes, and then plugging it back in. It is quite possible that there was a failure in the control module - the brains of the LG machine, and a reboot will help get rid of it.
• If the washing machine fills and immediately drains water, and then issues a PE code, then the reason may be incorrect installation. The drain is located below the level of the machine's tank, so the water flows by gravity into the sewer, and an error appears. Connect the washing machine to the sewer correctly yourself or use the washing machine installation service from RemBytTech.
• Check the connections of the wire loops going to the pressure switch. Perhaps they have moved away and need to be corrected.

If the above tips did not help fix the PE error, then a breakdown has occurred and your LG washing machine requires professional repair.

Repair

If this is the first time such a failure has appeared, you can try to deal with it yourself.

1. Disconnect the device from the power supply and wait 10 - 20 minutes. After that, plug the machine back into the outlet and check the result. Sometimes the problem lies not in the pressure switch, but in the control unit itself. If you reboot the system, the error may disappear. But, if it occurs constantly, and you have to turn the device off and on every time, it is better to call a technician and carry out diagnostics.
2. It is worth checking the wires that go to the pressure switch - if they are loose, they need to be carefully corrected, and the machine will work.
3. Check the water pressure - if it flows too slowly or, conversely, too quickly, this can lead to a failure in the system.
4. Sometimes water fills into the washing machine drum, and after a minute it immediately drains, after which an error code appears on the screen. This indicates that the drain is not installed correctly - if it is located below the drum level, the liquid will drain under the influence of gravity. In this case, you need to connect the device to the sewer correctly.

If these measures do not produce results, you need to call a specialist. Repair depends on the causes of the breakdown:

1. According to statistics, in 80% of cases the PE error occurs when the pressure switch breaks. Sometimes the problem lies in a blockage - in this case, it is enough for the technician to thoroughly clean or blow out the relay tube. If the pressure switch sensor is broken, it needs to be replaced.
2. If the error occurs due to a breakdown of the control unit, it will have to be replaced. In some cases, it is only necessary to replace the elements that are responsible for the operation of the water sensors. If the entire chip is damaged or melted, a new one must be installed.
3. Sometimes the problem is related to the cables and wires leading to the pressure switch - repair comes down to replacing them.

Most often, the technician can easily fix the problem. The repair price ranges from 1.5 to 6 thousand rubles. depending on the complexity of the breakdown and the cost of spare parts.

Possible faults requiring repair

Based on more than 5,000 repairs performed on LG washing machines, we have compiled a table of the most popular breakdowns that RemBytTech technicians encountered with the PE error.

In 80 - 90% of cases, the pressure switch, which controls the water level in the washing machine tank, is faulty. — from 2100 rub.

Signs

The LG washing machine does not start washing and issues a PE code.

How to fix

Sometimes it is enough to blow out the pressure switch tube if it is clogged. In other cases, the level sensor needs to be replaced.

The control unit - the microcircuit that controls the operation of the washing machine - has failed. — from 2600 rub.

Signs

The LG machine displays an error code immediately after pressing the START button or while the program is running.

How to fix

If the elements responsible for controlling the water level sensor have burned out in the unit, it is enough to repair it.

If the unit's processor fails or there is severe burning and melting of the microcircuit, it will need to be replaced.

Very often this is due to damage to the wiring inside the washing machine - from 2000 rubles.

The wire loop in the area from the control module to the pressure switch has frayed. Therefore, during vibrations during operation of the machine, contact appears and then disappears.

Signs

In the LG machine the PE error appears and then disappears.

Now let's figure out what you can do without calling a technician from the service center.

• If the problem is in the water pressure from the water supply, you can try opening the filler tap more or less, thereby adjusting the pressure.
• If a program failure occurs, immediately unplug the washing machine, wait 10–15 minutes and reconnect it to the electrical outlet.
• The pressure switch may not work due to a simple blockage in the tube. In this case, it will be enough for you to blow it out.
• You can correct the connections of the wire loops connecting the water level sensor. If suddenly you see that the wires are broken for some reason, you can connect them by twisting.

ATTENTION! The washing machine must be disconnected from the electrical network! Don't forget to insulate the connection with heat shrink!

• And, of course, you should check the correct installation of the washing machine, or more precisely, the location of the drain.

If you encounter any difficulties in eliminating the PE error yourself, you can always contact a specialist.”

Thus, we systematize the signs and causes of occurrence and methods for eliminating the PE error in a table.

If it is impossible to eliminate the PE error yourself and professional repairs are necessary, just call a specialist

Specialists will definitely contact you to save your LG “assistant”: they will arrive at the appointed time, find out the cause of the malfunction and, if necessary, offer and provide repair services.

Washing machine repair works daily from 8:00 to 24:00.

C.E.

The load on the electric motor has been exceeded.

There are mainly two reasons that cause an electric motor to overload:

1. Significant excess of weight and permissible volume of laundry.
2. Control system failure during power surge.

In the first case, check and unload the drum from excess laundry, try to start the machine again.

In the second, turn it off and on again after 20 minutes, start the washing machine.

In other cases, if the measures taken do not lead to results, we recommend calling a specialist.

PF

This code indicates a failure in the control system.

If this happened once, then most likely the cause was a voltage drop in the electricity. To eliminate this error, just start the washing machine again.

This error also occurs in the event of a short-term power outage.

If there are no problems in the home electrical system, then the problem is in the machine itself. To eliminate it, you will need certain knowledge and skills; it would be better to call a specialist from the service center.

How to determine if a washing machine is faulty?

Manufacturers of LG household appliances make a lot of efforts to ensure that the user does not experience inconvenience while using them. And that’s why the company has equipped its washing machines with a self-diagnosis function, which allows you to accurately identify the cause of the malfunction and make life easier for you and the repairman. This function can be used in two ways, all you need is a little time and a mobile phone:

1. This method is suitable for users of any cell phone model. First, you need to call the LG service center, where the operator will ask you to press a combination of buttons in a certain sequence, which are located on the control panel. After which the washing machine will produce a number of indicators that must be transferred to the service center operator. After processing the data, a technician who specializes in this breakdown will be sent to you.
2. Smartphone owners are invited to download and install a special LG ThinQ application and follow the menu items. The machine will diagnose itself and provide recommendations for troubleshooting on its own, or a specialist will be sent to you.

Also, to determine malfunctions, there are digital codes that are displayed on the display of LG washing machines. With their help, the machine makes it clear where the fault is, and the user only needs to decipher the code and try to deal with the problem on his own.

tE

This error means that the machine does not heat the water to the required temperature. The reasons for its appearance may be:

1. The heating element is broken.
2. Damage to electrical wiring.
3. The control module or thermistor has failed.

You can wash at low temperature settings, but do not put off solving this problem. It’s worth noting right away that you won’t be able to fix this on your own, and you need to call a repair specialist.

Control module is faulty

In modern washing machines, an important element is the electronic module. It is he who determines the program execution parameters, what needs to be turned on and when. But when there are overloads in the network or machine circuits, it becomes damaged and processes information incorrectly or gives the wrong commands.

In this position, correct operation of the SMA is impossible. Then you need to install a new module that matches the model with the firmware or restore the faulty one. You won’t be able to do this yourself - you need to contact a specialized service for repairing household appliances.

Control module

L.E.

When such a code is displayed on the screen, it is a signal that the motor in the washing machine is blocked.

We started the washing cycle and see that water is being collected, but the drum is not spinning. Let's look at the reason for this error:

1. Check the hatch for tightness. It should close tightly, with a characteristic click.
2. There is a foreign object between the tank and the drum. This may be small change not removed from pockets, a torn button or other foreign parts. Try to move the drum in different directions, and if you can’t rotate it, you may need to disassemble the washing machine tank, and only a specialist can do this.
3. If the error appears in the “Spin” mode, then most likely the tank is overloaded with a large volume of laundry, in which case it is necessary to remove the excess and start the process again.
4. Voltage fluctuations can also cause this error. Rebooting the system can help; the machine should be unplugged for 15-20 minutes, during which time all functions will be restored. If this happens often, then you should install a voltage stabilizer.

Reasons for the OE error appearing on an LG washing machine

There are several main problems that can cause the drum to fail to drain. Among them:

• the filter of the machine is clogged - if dirt, threads and other debris accumulate in the system, water stops leaving the drum;
• pump failure, in this case the unit cannot pump out liquid;
• sewer blockage - most often the pipe of the device itself is clogged, but sometimes the siphon under the sink causes the problem;
• a malfunction of the electrical controller, in this case the drainage system is physically in order, but the LG machine still cannot switch between modes;
• breakdown of the pressure switch - a broken sensor does not send correct information about the presence or absence of water in the drum.

If an OE error appears in an LG automatic machine, you must carefully inspect the unit and, first of all, determine the cause of the malfunction.

No water supply

A rather banal situation, but nevertheless it constantly arises. First of all, you need to check whether the tap is turned off. And also make sure that there is water in the pipes. Let us note another non-trivial situation. In some residential building layouts, there are so-called technical transit pipes. They pass through the riser through the apartment, but do not participate in its water supply.

Expert opinion

I work in the household appliance repair industry. Extensive experience in restoring washing machines and dishwashers.

Ask a Question

Household appliance repair technicians are faced with the situation that the washing machine is connected to just such a pipe. But sooner or later, the management organization may turn off this pipe. Therefore, if you have this particular position, then you need to check for the presence of water in it, and if not, switch.

Common cause

The OE error code in a Samsung and LG washing machine often means a serious breakdown of the control system. If all of the above steps do not lead to a positive result, you need to call a specialist. Only a qualified specialist can accurately identify the cause. If a breakdown of the electrical system is confirmed, repairs will be required. In the most difficult situations, the technician may recommend replacing the device. What to do in this case is up to the user to decide. After all, the cost of an electrical controller is sometimes equal to the cost of a new washing machine. Therefore, the final decision remains with the user.

In conclusion

If the OE error is displayed in an LG or Samsung washing machine, you need to fix the obvious problems. It is possible that there is too much detergent in the drum, or the wrong type of powder was used. Regular rinsing of an empty tank will help solve the problem. An important step in solving the problem is to check that the unit is connected correctly to the drain and water supply. If the error cannot be resolved, it is recommended to call a technician who will help solve the problem. Remember that the OE error is common for LG or Samsung machines, but not critical in most cases.

PE error, what does it mean?

Most often, the PE error occurs due to a malfunction of the water level sensor. That is, the filling of the tank did not occur in a conventional amount of time - (usually complete filling should occur within 25 minutes), or too quickly. Accordingly, the washing machine cannot figure out whether there is the right amount of water in the tank and issues a code. Due to the fact that adjusting the water level is critical for the machine, if the pressure switch malfunctions, the machine will most likely not start washing at all.

There are two possible problems with this:

On this page you can familiarize yourself with the table “Error codes for LG washing machine. The table provides a description of the error, the reasons for its occurrence and elimination. If a breakdown occurs and you cannot repair it yourself, please contact us. We will provide you with the service quickly and inexpensively.

Have you decided to start washing? As usual, we set the program, but suddenly all the indicators start to light up at once. They can be constantly lit or flashing. If you have an LG washing machine with a display, then the PE error will appear on it.

For the first time it could appear while the machine was operating, but then it was constantly on. In any case, the machine will not wash.

This means that we need to figure out what kind of PE error this is in LG washing machines.

Let's start with the fact that any washing machine has a so-called. To put it simply, this is a water level sensor that helps the machine determine how much water is in the drum.

So the error code PE indicates problems with this particular definition. However, it is not at all clear that the fault is in the pressure switch itself.

Thus, the essence and meaning of the PE error is:

the water is too fast, that is, in 25 minutes it cannot even reach the minimum level, or it comes too quickly, that is, in no more than 4 minutes.

In order to cope with this trouble, it is important to know what the possible reasons for the occurrence of a PE error in . This will give you the opportunity to fix it yourself, and professional repairs may not be necessary.
