Decoding fault codes for washing machines "LGi" - 1E, IE

In LG automatic washing machines, there is no error 1E. It’s just that many people confuse the Latin letter I with the number 1. The code appears on the display - IE.

This malfunction indicates problems with the water supply, which can be caused by a number of reasons. Let's look at the decoding and what needs to be done in each option.

• Reasons for the error
• No water supply
• Fill hose is clogged
• The mesh filter on the valves is clogged
• Problems with fill valves
• Pressostat
• Control module is faulty
• Water constantly leaves the car
• Catalog of LG washing machines with reviews

Reasons for the error

The actual algorithm for the appearance of the IE error is as follows - after selecting a program, the washing machine opens the inlet valves and water enters the tank. If within a certain time it has not reached the required level, then the electronic module issues a code that some read as 1E.

LGI washing machine panel

Let's look at the factors that lead to this:

1. The water supply tap is closed.
2. The inlet hose is kinked.
3. The inlet filter is clogged.

1. The fill valve is damaged.
2. The pressure switch is faulty.
3. Control module failure.
4. "Self-draining."

In LG washing machines, as a rule, it takes 8 minutes to reach the desired water level in the tank. We will consider each reason in detail, and what to do in these cases.

What does the OE error mean?

It often happens that an LG washing machine issues an OE code during a spin cycle or in the middle of a program while the wash is still in progress. The user faces a serious problem as the drum is full of wet laundry. To understand what happened, you will need to correctly decipher the error that appears on the equipment screen.

The OE code appears on the display when the washing machine starts the drain pump. In fact, at this moment the water should be removed from the drum, but in fact it remains inside, hence the error.

When programming the machine, the manufacturer provided a short period of time during which the attempt to drain the water should be repeated. If even after 5 minutes nothing changes and the liquid remains inside, the system issues an OE.

It is necessary to understand why the pump, which is responsible for removing water from the drum, cannot do its job. There may be several reasons for this:

• a garbage plug has appeared in the filter or hose;
• drain pump failure;
• debris may accumulate in the sewer system;
• the water level sensor has become unusable;
• failure of the electrical controller.

The last cause of failure often manifests itself not only in the described error. The user should observe how the equipment works by activating different operating modes.

You should not immediately send the equipment for repair. First of all, you need to check the hoses for blockages.

First, they check the quality of the sewerage system. To do this, open the taps and observe how quickly the water leaves. If everything is fine, you should check the filter and drain hose directly on the washing machine.

The first thing to inspect is the garbage filter. It must be cleaned well, preferably rinsed with water. If it is clean, but the error still appears, then the reason is different. The blockage may be between the siphon and the equipment filter. If the connection is made directly, and the drain hose is inserted directly into the sewer, then you should look for the blockage there. Heavy dirt plugs are removed using steel wire.

If there are no problems with clogging, you should pay attention to the operation of the pump. In this technique they are quite noisy. Extraneous sounds are easy to hear

However, if the equipment works quietly, this is also an indicator of a problem

Extraneous sounds are easy to hear. However, if the equipment works quietly, this is also an indicator of a problem.

The OE error may occur due to incorrect operation of the electrical controller or sensor responsible for the water level. In both cases, it is not recommended to carry out independent repairs; it is better to contact a specialist.

Online diagnostics of a washing machine

If your machine stops washing or rinsing clothes normally, then some kind of malfunction or breakdown has occurred.
You can try to find the problem yourself. Run diagnostics

Select which operation your washing machine does not perform:

1. Doesn’t drain 2. Doesn’t rotate the drum 3. Doesn’t spin clothes 4. Noises, knocks, buzzes when spinning 5. Doesn’t turn on

Checking the operation of the drain pump Is the drain pump of the washing machine working? Yes No I don’t know << Back

Clogged hoses in the washing machine If the sound corresponds to the normal sound that has always been observed when the device is working, the cause is probably a clog.

Was there a blockage in the drain hose? Yes

<< Back

The drain pump does not work! If the sound matches the normal sound of the drain pump, it is recommended that you check the drain filter first.

After cleaning, does the drain pump work and does the washing machine drain water? Not really

<< Back

Operation of the drain pump The sound of the pump is usually immediately audible and noticeable. If there is no sound, the pump is not working. We are looking for how to separately enable the water drainage program. As a rule, this is a separate option. After the program has been turned on, the pump should start working in 1-3 seconds. If everything is done correctly and the pump is operational, a buzzing sound will appear. If you hear no buzzing or other sounds when you turn on the program, the pump is probably faulty.

The washing machine does not rotate the drum. During the operation of the washing machine, such a problem may occur. Each model has a different drum operation. It rotates according to a given algorithm, which is set by the program. This principle applies to spinning and washing. If you are not sure whether the drum is not spinning or whether it is working, put the laundry in the washing machine. Start the spin program. If the machine is running, it will first drain the water and then start spinning. In this case, a rotational process will be observed. If rotation is not visible, then check the belt. First, turn off the program, then unplug the wire from the outlet so that power does not flow into the device. Now you need to remove the back cover. You will need to carefully inspect the drum belt. It is quite easy to determine whether it is in the wrong position or damaged.

Is the washing machine belt torn or stretched? Not really

<< Back

Broken drum drive belt If the belt breaks, it will be immediately visible. There are also often cases when the belt simply stretches, which is why the drum, accordingly, does not rotate. Do not allow the machine to operate if the belt breaks. It is important to check whether it has wound around the engine pulley or broken the wiring to the engine. The heating element and temperature sensor may also be damaged if the belt does catch the wires. It is imperative to ensure that the belt model is original. If you choose an unsuitable or low-quality product, this will affect the performance of other devices. How do you know what kind of belt you have? There will be a marking written on the old one, compare it with the one indicated on the belt offered to you. You can also find out belt information by car model.

Washing machine motor malfunction If a malfunction is not found, the block with wires must be disconnected from the electric motor. Carefully remove it. We visually evaluate the engine. It may have melting, cracks, or other effects that clearly indicate damage. We call the windings of the tachogenerator and the engine. It is important to understand that you can fully study how correctly the engine operates and whether there is a malfunction only at the stand. If rotation does not occur, there may be a problem with more than just the motor. Sometimes the cause is a malfunctioning electronic module. If a short circuit occurs in the engine, the module could be damaged, while the engine remains operational. Also, the wires could be damaged.

Repairing a washing machine that does not spin clothes After completing the washing process, the washing machine may not spin properly or may not start spinning. Firstly, look, perhaps another mode is set, which does not involve turning on the spin cycle at all. This happens, for example, with programs related to washing woolen items and delicate fabrics. To check, run the spin cycle separately. If the washing machine does not drain water, we proceed to check the pump.

Repair of washing machines, imbalance Modern washing machines place the laundry on the drum before spinning. This is necessary for quality work. Check if this feature works. Sometimes a situation occurs when things get wrapped up in a ball that cannot be unwound automatically within a certain time. At this point the work stops. You need to unwind this laundry yourself, lay it out and continue operating the washing machine. In this case, it is important to turn off the machine, and then, when the laundry is laid out, turn on a separate spin program.

The washing machine hums, makes noise during the spin cycle, rumbles, and makes a jet plane noise. If the washing machine makes noise during operation, making unusual sounds, it’s time to pay special attention to it. In this case, a visible breakdown or lack of functionality may not be observed, but the appearance of strange sounds indicates that it is time to look for a malfunction. It is important to understand that a new car that has just been delivered should be inspected for shipping bolts. If you forget to remove them, noise and vibration are inevitable. So, let's begin! We turn the washing machine drum and listen to extraneous sounds.

When rotating, do you hear extraneous noise, hum, balls rolling, does the drum move unevenly with slight jamming? Not really

The counterweight of the washing machine has come loose. The fastening of the counterweights must also be of high quality. If they are “loose”, it’s time to eliminate this defect. In some cases, you can notice that the bolts that secure the stones are completely missing. In this case, the connectors for mounting will be visible. The bolts need to be found and put in place - they probably simply came loose. A rumble heard while the washing machine is operating may indicate that the bolts have partially loosened. To check the bolts, you can simply push the drum. If it is secure, the bolts are fine. If it moves, there is a defect.

Checking the shock absorbers of the washing machine Checking the shock absorbers. If you hear vibration or excessive noise during the spin cycle, there may be a problem with the shock absorbers. Sometimes the washer moves. Now let's check the functionality. Remove the top cover. Click on the tank, move it five to seven centimeters down. A normal reaction will be observed if the tank rises sharply, jumping a little and stopping in its normal place. If this does not happen, the shock absorbers need to be replaced.

The washing machine does not turn on. It is worth trying to find the cause of the problem yourself and fix it. We start by connecting the device to the network. Next, click on the “network” button. In different car models, different indications are triggered: here either the display will start working, or, on the contrary, some other button.

Hatch lock lock (UBL) You can check it by turning on any of the programs. We choose what we will use. Click on the corresponding button. Don't forget to pay attention to the inclusion. As a rule, the process of activating a function is characterized by the presence of a certain sound, for example a click, with which the device makes it clear that pressing again is not necessary and the machine is already working. If there is no sound, the button may be broken. In this case, the main thing that must be done is to block the hatch and start working. If this happens, everything is fine.

No indication Checking the electrical circuit. If you notice that the washing machine does not respond to being turned on, it is first recommended to check the power supply. The outlet may be faulty. Try connecting another device. If the outlet works, you need to check whether the circuit that conducts energy through the washing machine from one element to another is intact. To do this, you will need a multimeter, which will help you fully analyze the ability to respond to an electrical signal at several stages of operation. If there is no network connection anywhere, this is probably the problem. We carry out this manipulation until we reach the electronic module. If we are talking about an old washing machine, here it will look like the device’s program. When you turn on the button, there should be no breaks in the circuit. If the circuit works, everything is fine electrically.

Deciphering codes and troubleshooting solutions

For convenience, we have presented a list of information error codes in the table. Below you will also find a brief description of possible problems and methods for eliminating them.

Error code Description Methods for solving the problem IE There is no water supply, the tank does not fill or fills very slowly (delay more than 4-5 minutes) Check the water pressure and the condition of the water supply tap. Inspect the fill valve and pressure switch for damage and breakage, if necessary, replace the broken part with a new PF Power failure, power supply problems Check that the power cord is connected correctly. Inspect the contact connections between the control unit and the network interference protective filter (FSP). Inspect the power indicator and check the connectors of the LCD panel board on the central control board CE Motor overload Adjust the amount of loaded clothes - drum overload negatively affects the operation of the motor. Check the functionality of the controller and UE motor Drum imbalance (no spin) Add or remove a few items according to the recommended drum load rates for the model. Distribute the crumpled laundry by hand. Check the motor drive and PE controller. Problems with the water level sensor (pressostat), the machine takes more than 25 minutes to fill water or less than 4 minutes from the start of the cycle. Make sure that the water pressure in the water supply is within normal limits (not too high or low). Check the operation of the pressure switch, replace it if necessary FE Tank overfilling with water Check the integrity of the contacts on the water level sensor. Inspect the fill valve, controller, water level sensor

Pay attention to the amount of foam during washing; if there is too much foam, wait until the foam settles and start the wash again. OE No water drainage (displayed after 5 minutes of operation of the drain pump) Clean the drain filter from dirt. Inspect the drain hose for kinks, damage, or blockages.

Eliminate damage to the drain pump and water pressure sensor HE Lack of water heating Check the heating element and its contacts, if necessary, replace the heating element dE Malfunction of the hatch door Try closing the hatch again. Check the serviceability of the hatch door lock, replace the broken device with a new one. Make sure the control panel is in good working order, inspect the electronic board tE Problems with water heating The temperature sensor has failed and there is no connection with the heating element. It is necessary to check the part for short circuits or broken contact circuits, diagnose the electronic controller E1 Water leakage, presence of water in the pan of the machine. The hoses, tank or other elements of the filler and drainage system have depressurized. The leakage adjustment sensor E3 may be faulty. Loading error Check the functionality of the SE control unit. Problems with the tachogenerator (Hall sensor). Inspect the tachometer and its contact system (the part is available in machines with direct drive and DD index). AE Automatic shutdown The float sensor has tripped. Check all parts of the washing machine that come into contact with water for leaks

Error dE in an LG washing machine may indicate a broken hatch door lock

It happens that an error occurs not due to the breakdown of parts or mechanisms, but due to ordinary carelessness. For example, a CL error in an LG washing machine means that the child lock function is activated. What to do in such a situation? To resume operation of the unit, you need to simultaneously press and hold two buttons on the control panel. For each model, these are different key combinations indicated in the instructions for the device.

To eliminate the CL error, you need to know the combination of buttons that turns the child lock on and off

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.

Elimination

Most often, the solution to a problem in the event of a washing machine breakdown is to replace the part, but when dealing with the LG brand, many things can be done with your own hands

The most important thing is not to forget about safety precautions before making repairs, since the most important components operate when connected to electricity with a voltage of 220 volts

If there is a problem with draining water, you should first check the integrity of the pump. It may not necessarily be damaged; problems with drainage also arise in the event of a normal blockage. First you need to drain the water, otherwise everything will end up on the floor. Near the round plug behind the drum or behind the panel (depending on the assembly version) you can find a thin hose plugged with a small plug. Having pulled it out and uncorked, all that remains is to carefully drain the water into any suitable container.

There is another fairly simple way - lower the drain hose to the floor level. Only after draining the water can you remove the pump and view the condition of the drain system. In most cases, regular cleaning of debris manually or using special products helps.

If the pump is broken, then you will have to do a little disassembly of the device:

• Be sure to remove the plug from the socket;
• pull out the dispenser; there is usually some residual water left in it, so it’s better to tilt the machine;
• remove the bottom panel and place the machine on its left side (in most LG machines the pump is on the right).

Before removing the pump, an obligatory step is to test it with a multimeter. It also makes sense to check the integrity of the electrical circuit or pump.

If the pump wears out, it will also need to be replaced. To do this, remove the dispenser in the same way and remove the bottom panel. Regarding the latter, a regular Phillips screwdriver may not always be suitable. For reassembly, it is best to photograph or mark all terminals and hoses. The hoses are secured with clamps, the filter plug is unscrewed when everything else has been turned off. There should be no problems with selecting a drain pump; they are usually universal and suitable for all modern models.

Before reassembling, be sure to clean off dirt and deposits. First, the pump is screwed on, then all the hoses and wires are connected back, after which the plug is closed. You can verify its functionality by simply running a short operation. For example, spin. And if everything is in working order, you can put the machine back together.

If the water heater breaks down, it needs to be replaced, but before doing this, you must check it with a multimeter or similar device. The heating element itself is located at the bottom of the tank, a grounding wire and several power wires are connected to it to supply current. After disconnecting the terminals, you can check the device for functionality.

To remove the device, simply unscrew the nut in the middle and press the pin a little. Next, remove the rubber seal. This must be done extremely carefully so as not to break the seal.

A replacement heater is also purchased with a seal included. If a temperature sensor is installed in the heater, it is not necessary to change it along with the entire set. It is enough to check the effectiveness of the work. Inside the tank for installing the heater there is a special bracket into which it must be installed. There should be no scraping sound when spinning the drum after installation. It makes sense to fill the drum with water and make sure that the seal does not leak.

If water is drawn slowly, it makes sense to check and clean the filter; it is located behind the inlet hose at the entrance to the machine.

If there is no water in the machine at all, in addition to checking and cleaning the filter, the valve is also tested using a multimeter. It is located behind the top cover, which can be easily removed by unscrewing a few screws.

If the machine does not wash, but the water gurgles, this is a sure indicator of wear on the mechanical part. Before replacing the valve, be sure to photograph the wires. The valve itself is removed after disconnecting all the wires and hoses; it is secured with special latches that need to be tightened by turning it slightly. When installing the part, you need to proceed in the reverse order.

If, on the contrary, it collects too much water, then a software reset may not help - you will need to change the pressure switch to a new one. The sensor itself is visible immediately behind the top cover and can be removed after disconnecting the terminal. But before that you can blow out the pressure switch. If a characteristic click is heard, it means the part is working properly and does not need to be replaced.

Fill hose is clogged

Inlet hose

Here, too, everything is simple and easy to identify the problem by visual inspection. This situation occurs when the washing machine is moved close to the wall. As a result, the inlet hose becomes bent and water will not flow.

A blockage may also occur. This happens especially often in the summer, when water is turned off to prevent pipeline maintenance. After it is fed into the hose, rust and debris may become clogged.

For cleaning, it is completely removed and washed under high pressure.

The mesh filter on the valves is clogged

This problem is similar to the one discussed above, but it occurs at any time. There is a mesh on the inlet valves, where the hose is connected, which ensures safe operation of the washing machine, without leakage.

Valve filter sma

This filter periodically becomes clogged. Depends, of course, on the quality of the water and the presence of devices in the apartment’s pipe system that prevent the passage of debris and sand.

In order to clean it, you need to perform the following steps:

1. Turn off the water supply.
2. Disconnect the inlet hose from the machine.
3. Using pliers, pull out the filter.
4. While tapping, rinse the mesh under pressure.
5. Put it back.

Ask a Question

Important! This can be done as a preventive measure if it is noticeable that water is entering the washing machine for a long time.

Prevention of breakdowns

To prevent breakdowns, you must follow some rules. First of all, be sure to clean the filter and hose once a year. It won't take much time, but the car will last a long time. You must remember to install a stabilizer for the washing machine. This is necessary to ensure that the voltage is stable, and then the control module and other parts will not be subject to voltage surges.

Water quality and assembly greatly affect the operation of the washing machine. But if all the rules of prevention are followed, the washing machine will serve for a long time. Many experts say that it is advisable to regularly disassemble it at least once every two years and check whether all the parts are in good condition. You can do this yourself or call a professional.

First of all, before washing, you need to check the pockets, because if something gets stuck in the drum, it will lead to damage. Do not wash at a high temperature often, this will make your LG machine last less. Don’t forget to open the lid after washing the washer and wipe the drum dry. It is important to remember that it is not advisable to interrupt the wash. This may lead to complete failure of the electronic module. Do not leave home while the washing machine is running, as there are times when the machine breaks down and this leads to serious consequences.

Many people do not know what to do if a breakdown has already occurred. You don’t need to do repairs yourself if you don’t have experience in this matter. The best option would be to call a good specialist so that he can figure out the breakdown himself. It’s better to pay for repairs right away than to only aggravate the problem later and the work will end up costing more.

Problems with fill valves

These devices operate on the following principle. The fill valves are constantly closed by default, and when you need to add water, the control module supplies voltage to the valves. And the coil located inside opens the shutter.

Sometimes they burn out and cannot perform their functions. In this case, replacement with new ones is necessary. This work can be done with your own hands, without the involvement of third-party specialists. The main thing is to buy a valve that matches the mounting and shape of your washing machine model.

Triple fill valves

You will need the following tools:

• screwdriver;

• pliers.

Pressostat

This device detects the water level in the tank, and if it is faulty, the LG washing machine displays an error code IE (1E). Note that there are two types of sensors: analog and electronic. LG uses mainly electronic ones. They generate a current of a certain frequency. And the filled tank should correspond to - 24.6 kHz. If within 8 minutes this frequency is not reached, an error appears.

The serviceability of the electronic pressure switch can only be diagnosed using an oscilloscope. These devices cannot be repaired.

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

Water constantly leaves the car

If the washing machine is incorrectly connected to the sewer, a “siphon effect” occurs, which is popularly called “self-draining”. That is, water flows out of the tank by gravity. The pressure switch sends a signal to the control module that it is not enough. As a result, the program execution stops, and a fault code is displayed on the display - IE (1E).

Simply install the machine correctly and the problem will go away.

As you can see, most of the reasons that lead to this error are quite easy to fix yourself.

UE error code

A very common mistake. The appearance of such an inscription on the display indicates that the device cannot spin washed clothes due to an imbalance in the drum. To put it simply, things are clumped together (not distributed evenly throughout the drum).

There are two options for writing code in which the cipher is:

• uE (lowercase u) means that the device is trying to independently redistribute the load and complete the operation normally;
• UE - The washing machine requires third-party intervention.
