Repair of washing machines lg

What is it for?

The service test of the LG brand washing machine is a special program incorporated by the manufacturer into the control microcircuit. This is a whole complex of actions that the LG washing machine itself performs in order to check how its key components and assemblies work correctly. The user himself starts the service test of the LG brand washing machine when it seems necessary to him, but in the future his participation is minimized.

The service mode is activated by special keys and does not last long, but it allows you to identify many breakdowns of the LG washing machine and thus help the master to localize the problem as soon as possible and make a quick repair. Of course, the test mode will not help determine any breakdown, in this case the master will have to strain his brain somewhere. But in general, this is a very, very useful feature that quite often helps users to save a little.

For example, if your washing machine has problems with the inlet valve, then at a certain stage of the test you will see an IE error on the display. Having easily deciphered this error, you will learn about the reasons that gave rise to it.

Where to begin?

We have figured out what the "Test" mode of the LG brand washing machine is for, now let's talk about how to properly prepare for its launch. In fact, everything is very simple, this is not a shuttle to launch into space! However, there are a few things to keep in mind.

• First you need to make sure that the washing machine is connected to all the necessary communications: water supply, sewerage and electricity.
• Starting the "Test" mode, take out the powder receptacle and rinse it from powder residues.
• Remove all dirty clothes and any foreign objects from the drum of your LG washing machine. Test mode can only be run on an empty drum. It is a good rule to remember this rule for those who like to store dirty laundry in the drum of the “home helper”.
• We close the hatch tightly, the hatch, and that's it, the simple preparation is over, you can start the "Test" mode of the LG washing machine.

Drain pump

Another device, the failure of which can cause an error, is a drain pump (pump). By the way, it is easier to determine the malfunction of this unit "by ear". The reason for this is simple - during the operation of the drain, the pump hums a lot. If you can't hear its work, or you hear a crackling and other sounds unusual for the pump, it is likely that you cannot do without a replacement.

Structurally, the drain pump consists of two parts: an electric motor and an impeller. Both parts can cause the drain to fail. Troubleshooting should start with the mechanical part. To do this, you need to remove the pump, remove it from the housing. Often, the cause of impeller jamming is threads that are wound around the shaft.

The impeller and the pump housing are cleaned of dirt and washed. Next, you should tackle the engine. Checking the windings is easy with a multimeter in resistance measurement mode. If the device shows an infinite value, the pump needs to be changed.

Replacing your pump is not difficult, but it is important to buy a quality replacement. You should not try to save money, you only need to choose original spare parts

This guarantees a long service life of the machine and saves you from unplanned expenses.

Checking the drain and drain hose

After it became clear what this error means, it is necessary to proceed to correcting the situation. The first thing to do is to make sure there is no large blockage in the sewer pipelines. It will not be superfluous to arm yourself with a long wire bent at the end and clean the drain as far as possible.

If the machine is connected via a siphon, it must be disassembled, remove the debris accumulated during operation, rinse with running water

Often the machine is drained directly, without a siphon, in this case, special attention should be paid to the connection point - this is an ideal place for blockage

The next in line should be the drain hose. Often trying to rationally use the small area of ​​the apartment, the car is pushed into a corner, as a result of which it bends. A blockage forms at the bend, which water cannot overcome. Another option is also possible - the hose is too long and something heavy was installed on it, or they constantly step on with their feet. In any of the above situations, there is only one way out - you need to change the hose.

Even if no physical damage is visible, it will be useful to remove the hose and rinse with running water. A clean drainage system will reduce the stress on the pump and contribute to a long machine life.

Likely Causes of the LE Error

As noted above, there are quite a few reasons for the LE error. These reasons, in one way or another, are associated with the electrician of the LG washing machine. Before looking for the reason due to which this error occurs, look at what moment, this very error occurs - when starting the machine, during operation at maximum load on the electric motor or at any of the indicated moments

This is all very important. So what are the reasons behind the LE error coming up?

• Problems with sensor or motor winding. If the sensor of the electric motor does not connect well or its winding is punctured by overload, the display may show a CE or LE error.
• The wiring that supplies power to the engine is broken or not connected.
• There is a problem with the surge protector of your LG washing machine.
• Voltage drop in the mains. If the drops occur frequently, then the LE error will pop up often, perhaps it will alternate with the PF error.

How to check the motor and wiring

Only a real master can immediately guess about the nature of the LE error. For this, we need to get to the engine of the LG washing machine, test it for faults, test the wiring, and only then draw conclusions. First, we need to get to the washing machine engine.

1. We disconnect the washing machine from communications and unfold it with the back wall towards us.
2. Unscrew the fasteners holding the back wall and remove it.
3. The motor on LG's direct drive washing machines looks different and sits right in the center of the drum. We find the engine - this is a large round metal disk located in the very center and proceed to check it.

Repair and inspection of the washing machine engine are described in detail in the article of the same name, which you can find on our website. We will not describe the process again. Let's better talk about how to check the wiring through which the power goes to the motor, because direct drive motors are very reliable and the likelihood that they are the problem is less.

• We find two bundles of wires going to the engine and disconnect them.
• We take a device called a "multimeter" and check the resistance of each core.
• If you find a broken wire, consider that the problem was in it, if the wires are intact, you need to look further.

Checking the surge protector, dealing with the electrical network

The LE error can be caused by faults in the mains filter of the washing machine. What to do in this case? How to check the surge protector for short circuits. First, you need to get to it.

1. Remove the top cover of the LG washing machine.
2. The surge protector is located on top, just in the place where the mains cable is fed.
3. We check the filter contacts and wires for breakdown with a multimeter. If the surge protector is working properly, you need to look further.

An unstable power supply can also cause the LE error.Our Russian electrical networks are simply created to disable electrical appliances. Constant failures, power surges break equipment not only in individual houses or apartments, but also in entire microdistricts. How to protect your “home assistant” and other equipment from such risks? It is necessary to supply a difavtomat and a stabilizer for the washing machine.

In general, it is best to have a professional electrician check the wiring in the house and install the necessary protective equipment. It is better, of course, to do this before buying a washing machine, so that later its connection is as safe as possible. Serviceable and suitable electrical wiring and protective equipment for electrical networks are the key to the smooth operation of the washing machine.

To summarize, we note that the LE code that suddenly flashed on the display of the LG washing machine can be caused by various malfunctions, but they are all related to the electrics, and not in any way to the water supply, as the 1E code tells us. Be careful and correctly decode error codes.

What does error mean?

LG washing machine throws IE error code at the most inopportune moment. Usually everything is ready to be washed, the laundry is loaded, and the compartments are filled with powder and conditioner. Such two letters on the screen signal that the equipment was not able to draw water in the time allotted for this process. It is worth noting that while the motor of the machine is running, a characteristic noise is heard. However, the water either does not enter the drum at all, or it pours out in a small stream. The error can also manifest itself in equipment without a display. In this case, the prewash and main wash lamps come on at the same time.

After starting the program, the washing machine has about 8 minutes to draw water into the tank for further operation. If, after a predetermined period, there is no liquid or there is not enough liquid, then the electronics sees the problem and stops working. Washing will resume after solving the problem.

Preparing for work and disassembling the washing machine

Actually, disassembly is loudly said, in order to gain access to the water heating unit, it is enough to simply remove the back cover, and this is not difficult. Of course, before starting work, you must remove the water from the washing machine. It is easier and more efficient to do this by running a cold wash program.

Next, the LG washing machine must be de-energized. Pressing the power button is not enough, you must unplug the power plug. It is also useful to disconnect the inlet hose so as not to provoke a small flood.

The washing machine is being turned around. It is advisable to take it out to the middle of the room in order to provide yourself with maximum comfort. You can go directly to disassembly.

Using a Phillips screwdriver, unscrew the bolts securing the cover. Most often there are four of them. Use any narrow flat object (a regular screwdriver or knife) to pry the clamps, pull the panel towards you.

Why does this code appear?

The designation is shown on the display of the device after the end of the running program. The washing machine generates an OE error if the waste liquid has not been drained from the tank after five minutes after the end of the wash cycle. It is not necessary that the water will not leave at all, perhaps the rate of its removal from the system is simply much lower than the standard.

What to do in such a situation? Experts see several reasons that can lead to a similar problem:

• clogging of the trash filter and snail;
• kink or crack in the drain hose;
• failure of the pump responsible for draining the water;
• blockage in the sewer pipe;
• malfunction of the pressure switch.

The list of probable causes is rather big. To remedy the situation, there is nothing else to do but to check each element of the washing machine's drainage system, and also to make sure that the sewer network is not clogged.

What to do?

Before disassembling the unit and looking for the cause of the breakdown, try restarting the machine. Sometimes one-time failures occur in the control unit, which can be eliminated by restarting the system.Disconnect the appliance from the mains for 10-15 minutes, then turn it on again and continue washing.

A clogged drain filter is the most common problem that leads to an OE error

If this does not help, it is necessary to check the elements of the drainage system. Start checking from the most accessible places:

1. Check the drain filter for clogging. To do this, open the bottom panel at the bottom of the washing machine and unscrew the part counterclockwise. Remove accumulated dirt from the filtration compartment and rinse the filter under running water, then reinstall it.
2. Inspect the drain hose. It can be clogged or pinched, preventing water from flowing freely from the tank. Disconnect the element and rinse it under running hot water, if it is heavily clogged, push through the dirt plug with a steel wire.
3. Check the drain-to-drain connection for blockages. To do this, unscrew the pipes, clean the elements from dirt and rinse them under running water.

Most of the elements of the drainage system are easiest to reach through the bottom of the unit.

If the previous steps did not yield results, you must continue to search for the problem inside the device. When the LG washing machine gives an OE error and the pump does not make sounds or is too noisy, most likely the problem lies in it. You can get to the drain pump through the bottom of the unit. Disconnect the element carefully and check the impeller for blockage, which collects debris that has passed through the filter: hair, wool, threads, etc. When the pump has been cleaned, reinstall it in the reverse order. If the code still appears after cleaning, the pump may need to be replaced.

A burnt-out pump cannot be repaired; it must be replaced with a new one.

If you manually drain the water from the tank and after that it does not collect into the drum, there may be a problem with the water level sensor. First check the tubes that lead to the device, they may be clogged and need to be cleaned. After cleaning, there is still no set and water drain? This means that the pressure switch needs to be replaced.

To inspect the water sensor and its elements, you must remove the top cover

When you have ruled out clogging and damage to the drain system, but the machine still writes an OE error, the problem may be caused by a broken controller. If you do not have the skills to work with electronics, it is better to entrust the diagnostics and subsequent repairs to a specialist. Replacing a control module is usually expensive.

As you can see, it is almost always possible to repair the unit when the OE code appears at home. If you follow the operating rules and carry out the prevention of contamination of the drain system, in half of the cases it will be possible to avoid this problem.

Solutions to the problem

If the LG washing machine stops and the display shows the error code tE, you need to urgently take action. You can call a specialist or take the car for repair, you can try to cope on your own. Whichever option you choose, you just need to overload the car before proceeding to action.

To do this, turn off the washing machine, unplug the power cord from the outlet and wait a few minutes. This activity will help in the event of a software failure that could result from a surge or voltage drop.

Restarting the program may be successful, but not necessarily. If the error persists, it's time to look for the master's phone or take up the tool yourself. That's right, it will not be possible to get rid of the tE error in LG SMA without partial disassembly.

PE

PE failure may appear during washing, spinning or rinsing. In the future, the failure occurs constantly.

Water sensor problem

The presence of the PE code means a malfunction in the pressure switch. Due to a problem, the sensor cannot detect the amount of water in the tank.

Checking the water pressure in the water supply

Lack of pressure or excessive pressure often leads to error. If you notice a failure, you should check the pressure level.

Pressostat performance

In most cases, the cause of the error is a breakdown of the pressure switch. If the pressure switch tube is clogged, it is enough to blow it through, and in other situations, replacement is required.

Test progress

To start the test mode on the LG brand washing machine, you must press the following keys at once: "turn on", "temperature", "spin". An example is shown in the picture below.

If you have LG without a Russified control panel, then you should hold down the similar keys with the names "TEMP", "SPIN" and "POWER". After taking this simple step, you will see that the control panel of the LG washing machine lit up with all the lights just like a Christmas tree.

Now we just have to press the "start" button and the test of the car will start safely. Then a logical question arises: where will such a test begin, what will be checked and, most importantly, what should the user do in this case? Everything is simple here.

1. As soon as you press the start button for the first time, the LG washing machine will start testing the drum rotation in the opposite direction, that is, counterclockwise.

1. Pressing the start button a second time will check how the drum will rotate when the pre-spin mode is started.
2. Press the start button a third time and the LG washing machine will check how the drum rotates at its maximum possible speed.
3. A fourth press on the same button will start the inlet valve and pressure switch test. During this test, the machine will fill the tank with water. Moreover, you can observe the process of the flooding on the display in the form of a digital value. An empty tank is indicated by numbers, about 261-263 and when it is normally filled with water, you will see a number about 230.
4. Pressing the "start" button for the fifth time activates the check of the heating element operation. Nothing changes on the screen.
5. The sixth press "start" controls the water temperature. Again, everything is still on the display.
6. We poke the "start" button again and the check of the engine operation in normal mode will start, that is, clockwise rotation. The display will show changing numbers indicating the RPM.
7. The eighth stage of the LG washing machine test is to check the heating element for quick on / off. The control microcircuit activates the heating element several times for 3 seconds. At this time, the display will show a figure indicating the temperature of the water in the tank.
8. And finally, the ninth press on the "start" button will allow the washing machine to start the drain pump test, which will immediately begin to drain the water from the tank.

As soon as the drain pump has removed all the water from the tank, the numeric value on the display will increase from 230 to 261-263. If the water has not completely disappeared, then the final number 252-259 will appear on the screen. In this case, you will need to figure out why the water from the tank does not leave to the end. By pressing the start button for the LG washing machine for the last time, we end the test mode.

So, as you can see, there is nothing difficult about testing your LG washing machine yourself. The main thing is not to change the order of actions described in this publication, and then everything will go well. Good luck!

Causes of the "LE" error

If the error code "LE" appears on the display of the device, then this indicates that a blockage of the electric motor has occurred in the LG washing machine. Both very minor breakdowns and serious malfunctions can lead to the occurrence of such a problem, for the elimination of which it will be necessary to disassemble the household appliance. Given the complexity of some work on troubleshooting the washing machine, before equipping yourself with a screwdriver and wrenches, it is recommended to check the washing machine for the most common and easily fixable problems:

1. Open the door of the washing machine, then close it again until a characteristic click appears. Often household appliances of this brand refuse to work due to a loose loading door.
2. Disconnect the household appliance from the electrical network, and reconnect after 5 - 10 minutes. This recovery method can be very effective in the event that a significant voltage surge has occurred, which triggered the protection built into the electrical circuit.
3. If a malfunction occurs during the spinning process, then the weight of the loaded laundry may exceed the maximum permissible values. This situation occurs especially often in the delicate wash mode. In this case, to resume the operation of the device, it is enough to open the door and remove some of the laundry from the drum.
4. Check the voltage in the electrical network. If this indicator is significantly less than the manufacturer's recommended value, then with each decrease of this parameter, the washing machine will pause with the appearance of the error code "LE" on the display.
5. Manually try to turn the drum of the washing machine to make sure there is no blockage of this part as a result of any object falling into the space between the housing. To eliminate such a malfunction, it is enough to remove the stuck object, but if the drum does not turn due to jammed bearings, then a rather complicated repair of the washing machine will be required.

Unfortunately, the inoperability of the device can be caused by problems that are problematic to eliminate on their own, which means that it is necessary to contact qualified specialists.

Prevention of malfunctions

Most breakdowns and malfunctions can be avoided if you strictly follow the operating instructions, correctly select programs and modes. Trust the installation of your washing machine only to professionals. During operation, we recommend following the rules:

• control water quality;
• check the voltage in the mains and turn off the device in case of power outages;
• adhere to the optimal load weight of laundry;
• use quality detergents;
• check pockets before washing so that small parts do not fall into important parts of the washing machine;
• clean the filter at regular intervals.

AE

An AE error on the machine's display indicates a failure when trying to turn off automatically. An unplanned shutdown may occur due to a problem.

Auto power off

The presence of the auto-off function saves the resources of the washing machine. If there is no action for a few minutes after starting the power supply, the machine will turn off.

Float sensor

The probable cause of the AE error is the presence of liquid in the sump. In this case, a leak occurs and the float sensor is triggered.

Checking nodes for leaks

If you notice a malfunction, you should check the assemblies of the drain pipe. Leaks are often caused by sharp objects hitting the inside of the drum.

Troubleshoot IE error

In the event of a breakdown, you first need to understand why exactly this happened. If water is collected, then the pressure switch will have to be changed. Every owner of an LG washing machine should know how to fix the error. If the liquid is not audible, then it is necessary to first check the hose, as it could bend. Blockages often occur, for this you will need to clean it. It will be necessary to completely remove the hose and rinse it well.

The filter is also clogged with dirt, there is a mesh in the valve. It will need to be cleaned. The first thing to do is turn off the water completely. Then remove the hose and carefully pull out the filter. Rinse the mesh thoroughly and replace. This should also be done for prevention.

There are times when a valve breaks down and needs to be replaced. You can carry out this procedure yourself, you just need to purchase a suitable part and install it correctly. To do this, you need to take and disconnect the inlet hose, then remove the cover of the washing machine. At the same time, unscrew the two bolts that hold the valve and disconnect it from the pipes.

Next, check the condition of the rubber bands, because they are a common cause, because of them, a malfunction occurs. If this happens, it is necessary to replace the rubber bands, but sometimes the problem lies in the breakdown of the valve electronics. Then you will need to purchase and install a new part.

The pressure switch monitors the liquid level in the tank, and if any problem occurs, error 1e appears. If a part breaks down, then the repair cannot be done, it is necessary to purchase a new one. You can check if the pressure switch is working with an oscilloscope. Oxidation of wires and contacts can also occur, in order to correct the problem, it is necessary to treat the product.
The control module can also fail, because it is responsible for all the work of the LG SMA. In this case, you will need to purchase or flash the module. It is not recommended to do this on your own, since only an experienced master should understand such matters.

If the washing machine is connected incorrectly, then there may be a fluid leak from the tank. Then it crashes and the IE error appears on the screen. To solve the problem, you will need to make the correct installation of the LG washing machine.

If all the methods have been tried and it was not possible to fix the breakdown on your own, then it is best to contact a professional. He will help find the cause and eliminate it. Many do not even realize that if you do the repair of the modular control yourself, the washing machine may fail altogether. The best option would be to call a master who understands this well.

There are also cases when the 1E error appears due to some simple reasons:

1. A person forgets that he has turned off the tap and water does not flow to the washing machine. It is necessary to check whether it is actually closed.
2. It happens that there is no water in the tap. Perhaps there were some disruptions in the water supply.
3. It often happens that the stopcock is not fully open, so the washer takes up water for a long time and, as a result, gives an error.
4. You need to try restarting the machine and turning it off for 10 minutes and then turning it back on. There may be a minor glitch in the modular control.

Therefore, there is no need to panic if an error appears on the display, it is possible to eliminate it quite simply. It happens, of course, that repairs are needed, but you should not be upset, because the main thing is that after the breakdown is eliminated, the LG machine will work again

The most important thing will be to find a good specialist.
