LG washing machine - error DE - washer.tomathouse.com

In the event of a breakdown, washing machines of this brand display a code that allows you to better understand what happened. There are quite a lot of error codes and, at first glance, it is difficult to navigate through them. In fact, each code refers to strictly defined faults and can help you decide what to do in each specific case. This article will tell you what to do if a DE error occurs on your LG washing machine. If this model does not have a display, the error signal is transmitted by simultaneous flashing of the lights on the “Temperature” control panel, as well as “Wash” and “Rinse”.

Finding the cause of the breakdown

In order to begin repairs, it is necessary to accurately determine the cause of the breakdown, although the instructions say that the car’s hatch is simply not locked. At first glance, it will be enough to simply close it and the machine will work without problems.

In fact, there are several possible options for what DE means in this situation:

A special lock is attached to the hatch, which looks like a hook. If it is faulty, you will not be able to slam the hatch cover. In this case, it will not be possible to fix it in the closed position, and the fact of closing the lid will not be able to fix the control controller.
The locking device uses a spring and a special clamp. If they have moved, you will not be able to close the lid.
For a washing machine, it is important not only that it is closed, but also that it is registered by the corresponding sensor. If the latter is broken, this will not happen. Moreover, even if the hatch is closed and fixed, the control controller and diagnostic system will not know about it.
The start sensor, the readings of which are necessary to control the correct operation, may also be damaged.

The listed errors are typical. Of course. In most cases, they lead to this type of breakdown, but only a specialist can give a full guarantee.

What to do if this malfunction occurs

Errors recorded by the washing machine can be divided into three main types:

In rare cases, it may happen that the error simply stops appearing over time. In this case, it turns out that it went away on its own.
In this situation, the user makes certain efforts, after which the machine becomes operational.
This category refers to the most difficult cases. You have to invite a specialist. He will decide how to fix the breakdown, make repairs and fix the machine, but the cost of repairs will be quite high.

Therefore, a reasonable course of action would be to first do everything possible, and if this does not work, contact a technician.

If the display shows DE, you need to check for possible small objects that prevent the machine from closing. These could be torn off clothing parts or buttons. It is also possible that small objects, such as coins, remained in the pockets of the clothes intended for washing.

With almost any error code, there is a small chance that this is a system failure.

To check this version when it issues DE, you need to unplug the washing machine and wait a while. Before turning off, you need to close the hatch more tightly. Usually the wait is from 10 to 20 minutes.

After this, the machine is plugged back into the network. The hatch must be closed tightly.

If the diagnostic system failure message no longer appears, it can be assumed that it was an accidental failure.

It is advisable to repeat this procedure several times with a break of 10 - 15 minutes.

If the attempt does not produce results, it is necessary to perform the diagnostic procedure for the situation when the error code DE is issued, developed by LG specialists:

You need to see how much the parts have worn out. To do this, you need to inspect both the hatch closing mechanism and the hinges to which it is attached.
In some cases, wear on the hinges leads to misalignment of the hatch. To correct the situation, it will be enough to tighten them up.
One of the common causes of the error when DE is on is a broken handle that is used to close the hatch.
The check begins with inspecting the hatch cover and determining the serviceability of the locking hook. In order to make sure it works, you need to move your finger a lot. The hook is usually made of plastic or an alloy called silumin. If it is broken, it cannot be repaired. To replace it, you will have to buy a complete locking mechanism.
If no malfunction is found, you need to check the counter part of the locking mechanism. It needs to be disconnected from the machine. In order to do this, you need to unscrew the two screws that hold this part.
Now we pull out the locking device, making sure that the sensor is still connected to the control controller.Now turn on the washing machine. On the narrow part of this device you can easily see the contact. It needs to be closed.
Let's see if the diagnostic system gives this error. If this is not the case, we check whether it is possible to set the washing mode in this situation. If this is possible, the conclusion is that the hatch locking device is faulty and needs to be repaired or replaced.

If this procedure shows that the lock is working properly, you need to continue the diagnostic procedure. This suggests that the cause of the failure is faulty electronics. To check this, do the following:

First you need to remove the plastic cover. To do this, use a screwdriver to pry off the plastic clips that hold it in place.
Now you need to disconnect the electronic unit. To do this, you need to unscrew the screws that hold it in place.
The block consists of two parts. One of them, which is larger, includes an information display. The other, smaller one, controls the startup and shutdown of the machine. We need a second board.
We simply disconnect the large board and put it aside.
Now we have to carefully examine the remaining board. In this case, you need to look for possible mechanical or other damage to it.
If the board appears to be in good working order and there is no damage, then all that remains is to contact a specialist.

One of the characteristic signs of damage to the control board is a burning smell.

It is also possible that the wires connecting the sensor to the control board may be damaged.

Repair algorithm

If damage was found during the diagnostic process and its correction is available to the user of the washing machine, at this step we proceed to repair.

If the contact with the sunroof lock sensors malfunctions, turning on every once in a while, then it is enough to clean it and the malfunction will be eliminated.

If the sunroof latch is faulty, it can be replaced by purchasing a new one and installing it. If you want to do this, you can repair it yourself or have it done by a specialist.

If you find damage or traces of burnt contacts on the small control board, you need to thoroughly clean it, then resolder the connections that looked faulty.

Conclusion

The issuance of error codes allows you to understand what to do, how to proceed with repairs in the event of a breakdown, and also, when talking with a specialist, it will allow you to accurately describe the breakdown that occurred. Knowing the error codes for LG washing machines will help you feel confident when problems arise.
