How to clean the filter in an LG washing machine: instructions for cleaning the drainage pump drain element and water supply hose parts

SMA ElG combines wide functionality, nice design, relative durability and reasonable cost. A breakdown of an LG washing machine due to the fault of the manufacturer is a rare occurrence, but due to unfavorable factors it happens often.

Basically, problems occur for the following reasons:

water is too hard;
voltage drops in the network;
careless use of the machine;
neglect of care and prevention.

The latter is what causes blockages. Usually, the user manual describes in detail how to clean the filter in your LG washing machine. But if you have lost the instructions, we will tell you in detail how to remove the part and clean it of dirt.

This will prevent a lot of possible breakdowns in the future.

Why is cleaning necessary?

An element clogged with dirt provokes problems:

An unpleasant odor appears - a consequence of the proliferation of dangerous pathogenic flora from hair and skin particles.
The pump is damaged - difficult draining leads to constant overload and critical heating of the pumping unit. Debris can get into the impeller and jam it.
The drainage mechanism is disrupted - clots of dirt become in the way of water movement along the main line.

A clogged filter leads to breakdown of the “helper”. How to know when it's time to clean the drain filter:

increased washing time;
the machine works with effort;
the display shows errors;
The electronics get confused - the washing modes get confused.

The most unpleasant thing is that the machine does not rinse, spin, or drain the water. A sudden stop of the machine will require professional intervention.

What happens if you don't clean it?

Ignoring cleaning can have unpleasant consequences and can even lead to component failures.

Unpleasant smell

If the filter is not cleaned, dirt, mucus and debris will accumulate in it. This is a suitable environment for the development of microbes. The constant presence of moisture causes all these accumulations to begin to smell unpleasant, spreading the stench to the tank and drum. As a result, things will also begin to emit an unpleasant aroma after washing.

Deterioration of drain

A clogged filter part of the LG washing machine prevents the water from draining normally. When completely filled, it can even completely block the flow of used water into the sewer.

When cleaning the filter, when draining no longer occurs normally, a fairly large volume of water will pour out through the emergency drain tube; this must be taken into account when preparing the container.

Pump failure

If a foreign object that has already entered the filter slips back into the pump, the pump may break. The impeller blades and the impeller body itself are in the “risk zone”. If this happens, the pump will have to be replaced.

How often is it needed?

Frequency of the procedure, according to the manufacturer’s recommendation: every 3-6 months . But this is conditional - the prevention time depends on the frequency of turning on the device, the weight of the loads, and the degree of soiling of the laundry. In large families with children, the car is turned on every day, so it is serviced once a month.

In winter, warm, fluffy items made of wool, flannel, and flannel are washed - the element quickly becomes clogged with fabric substrates, so they clean it more often. The machine is cleaned immediately after washing natural down jackets and feather pillows.

Consequences of prolonged blockage

The frequency of cleaning the drainage unit depends on the intensity of use of the unit. The manufacturer recommends removing debris at least once every 2 months. Some users do not comply with these requirements, which leads to complete clogging of the device and freezing of the error signal indicating the impossibility of pumping out water.

As a result of the filter being completely clogged, it is difficult to open and clean. To do this, you will have to remove the drainage unit and clean the internal cavity through the pump discharge pipe. The periodic appearance of an error signal on the display indicates the need to inspect the filter and remove the blockage.

A clogged filter disrupts the operation of the pump, which rotates idle, and can lead to its breakdown.

What filter elements are included in LG?

The machine has two filters: for water supply and drainage. Where to find them:

An inlet (drainage) filter in the form of a fine mesh is installed at the valve that connects the machine to the water supply.
Located at the top right side of the rear of the machine.
The drain filter element, which prevents small fragments from entering the drain pump, is located at the bottom of the washing unit, closer to the left edge.

On modifications with vertical and horizontal loading, the location of the elements is approximately the same.

Preventive measures

Despite the fact that the filter catches many small objects, including specks of dust, it is advisable to adhere to the following preventive measures:

You should not send things for washing that have lint and hair coming out of them.
They are not only capable of clogging the drain filter, but also accumulate on other parts, including the heating element, literally welding to it and causing rapid wear of the heating element.
Do not allow small objects to get into the drum while relying on the filter. Coins, nails, paper clips and other similar objects can cause a lot of trouble, including damaging heating element tanks.
If the filter is broken, it must be replaced.

Preparing for cleaning

Cleaning takes 10-15 minutes. Proceed as follows:

The floor near the device is covered with polyethylene or a rag.
They turn off the water supply - you may have to move the machine or lift it during the process so that the floor will not be flooded with water.
Turn off the electrical power - this is a common safety requirement for servicing all household appliances.
Find the location for installing the filter; it is covered with a door-lid (false panel).
They open the door. It is equipped with a latch and holds tightly. Usually the panel is easy to open by hand. If you are comfortable, you can pry the cover with a flat screwdriver, move the tool to the side, and fold the panel towards you - in LG models it is not completely removable.
There is a filter behind the door. It is inserted into the pump chamber and looks like a large plastic plug with a small protrusion. The dirt trap is equipped with a thin hose for emergency drainage.
Pull the hose out of the fastener (this does not require effort), unscrew the plug, and drain the water into a prepared container.

The machine completely pumps out water only from the tank; a certain amount always remains in the drain system. It is removed before cleaning the mechanism.

Cleaning the drain

When the drum is dry, begin cleaning the part. How to do it:

take the element by the protrusion and turn it counterclockwise until the filter is completely free;
remove the element from the seat;
remove large debris with your hands: threads, hair, foreign objects;
The part is placed under a stream of warm water, a dish sponge with an abrasive surface is cleaned from deposits, washed with detergent, and rinsed;
inspect the hole from which the filter was removed, clean it with a sponge and rag to make sure that there is no dirt left, illuminate it with a flashlight;
the clean part is inserted into the socket evenly, without distortions, and screwed tightly;
close the plug on the emergency drain hose and put it in place.

The filter should not be washed with very hot water or aggressive cleaning agents - the plastic parts may become deformed.

How to clean the filler?

Water entering apartments and washing machines through the central water supply pipes carries:

metal impurities,
particles of rust and sand,
lime deposits.

All this is captured by the inlet filter - it looks like a mesh in the form of a cylinder.

Clean it like this:

De-energize the device.
They turn off the water.
They move the car away to get to the rear wall of its body.
The floors are covered.
Loosen the nut with the rubber gasket holding the filler sleeve. Scroll it counterclockwise.
Remove the filter element from the valve. To do this, grab the protruding part of the catcher with pliers.
Clean and rinse the mesh under running water - it is convenient to use a toothbrush.
Some LG modifications have duplicate grids installed - they are also cleaned.
The clean element is put in place.
Connect the water supply hose to the unit body.
Tighten the fastening nut, not forgetting to insert the rubber ring.

Fasteners often wear out. If necessary, components are changed while cleaning the filter element.

Some useful tips

In the vast majority of cases, the owner of a washing machine cannot influence the quality of water in the water supply, as well as the condition of the pipes; the only thing that can be done to protect yourself from the need to clean the inlet valve mesh is to purchase an external water filter. This is far from the cheapest device, so purchasing it only makes sense if there is a large amount of debris in the tap water.

Every car owner can reduce the likelihood of drainage filter clogging. To do this, you need to follow a number of simple recommendations:

Before washing, be sure to check the pockets,
if there are loosely sewn buttons on clothes, it is better to rip them off and sew them back after washing,
children's toys should be washed only in special covers,
covers are also necessary for clothes embroidered with beads, rhinestones, and other decorations that may come off during washing,
Do not wash torn clothes under any circumstances, since during washing there will be a lot of threads and rags; before throwing the torn item into the machine, it must be sewn up,
Heavily soiled items should be washed separately before placing them in the machine drum,
things from the beach must be pre-soaked, sports shoes must be washed in a special case.

Compliance with simple rules will guarantee a long service life of the washing machine, but this does not exempt you from the need to periodically check the condition and clean the filters. It’s not difficult, it won’t take much time and won’t take a lot of effort, but it will bring a lot of benefits. Clean filters will ensure the normal functioning of the machine and protect the owner from having to remember the basics of hand washing during an unexpected repair.

How to check the machine after the procedure?

After cleaning, check the washing machine for leaks - set the test rinse mode. If no streams or drops of water appear from under the filter, close the panel.

Sometimes the test rinse shows a water leak. Users are looking for reasons:

misalignment of the part along the thread, when the part was placed crookedly in place, or the element was loosely tightened;
gasket defect - dried out over time;
Damage to the thread - this happens if the filter was pulled out forcibly or tightened too tightly.

Possible errors and options for correcting them

Problems often arise after cleaning the filter. The most common is water leakage. The cause of the malfunction may be an incorrectly or unevenly installed filter. To correct the problem, remove the part and reinstall it.

A worn gasket can cause the problem. As a result of long-term use, the rubber dries out and cracks; in addition, it may be damaged when the filter is removed. To fix the problem, replace the gasket with a new one.

The cause of the leak may be damage to the filter or threads. In this case, the part needs to be replaced.

If the filter is installed incorrectly or damaged, there is a high risk of leakage. Before closing the compartment, turn on the unit in test mode and make sure it is operating normally

Possible problems

The work doesn't always go smoothly. Sometimes users are unable to unscrew the part or remove it. This occurs if the sump pump assembly is not cleaned often enough.

What they are doing:

Use pliers. Use a tool to grasp the protrusion of the filter, turn it carefully so as not to break it.
Clean the element through the removed pump. This can be done by owners with plumbing skills.

Average users are advised to call a service technician.

Step-by-step instruction

Unscrewing a soured washing machine filter is sometimes very difficult.

It is necessary to act carefully, not to apply too much force, so as not to break the machine parts.

In addition, you need to make sure that the rotation is in the right direction - counterclockwise. To resolve the issue, you can use several methods.

Using a tool

One of the easiest options is to try to grab the filter handle with pliers and unscrew it

Caution is required here as the force is quite large.

Without proper calculation, you can break the handle of the knot. You need to act slowly, rocking, turning the plug in both directions and gradually increasing the amplitude.

If the filter can be turned a quarter turn but does not go any further, do not apply force. It's better to try another way.

Removing the drain pump

If you cannot unscrew the cover using the usual method, you can try dismantling the entire pump. As a rule, it is attached to the machine body with two screws, but there are a lot of manufacturers, so any options are possible.

Getting to the node from the other side is much more difficult. Partial disassembly of the machine body will be required. In order to determine the location of the device, you need to look inside the case.

The easiest way is to tilt the car and look from the bottom. Sometimes it is not there at all, or it can be easily removed. Then you can support the housing on a wall or other strong object and disassemble the pump from below.

Another option is to turn the car around, remove the back wall and disassemble the pump from the back. This method is somewhat worse, as you will have to reach for the part through the entire thickness of the machine, which is filled with other parts.

However, the issue is completely solvable. The main thing is to acquire the necessary tools and ensure maximum ease of work.

The insides of the machine should be well illuminated, act carefully, trying not to damage the plastic tank of the machine.

Deflection of the machine and tapping on the filter unit

One effective way is to carefully rest the machine on the wall at an angle of approximately 45° and tap the filter with something soft.
The easiest way is to use your own fist. Shock may cause debris and particulates to fall off the filter cover. After this procedure, it is often possible to unscrew the filter without much difficulty.

Sometimes things don't work out the first time. You can try repeating the procedure several times if any positive changes are noticeable.

The main thing is not to overdo it and not to drive the lid in even harder. Then the only option left is to completely break out the problem unit and replace it with a new one.

Breaking out

Sometimes situations arise when no methods help. For example, the filter cover broke immediately (or during previous attempts), or when unscrewing, parts of the housing, pipes and other elements were damaged.

If such situations arise, all that remains is to resort to the last, most drastic method - break out the filter in order to get rid of the defective unit and replace it with a new one.

To perform the work, the machine is placed on its side and work begins from the bottom. Unscrew the mounting screws. If this cannot be done, they are drilled out or carefully cut off.

Some craftsmen destroy the plastic case from the inside and gradually break off pieces of plastic from it. After some time, the filter and pump can be disconnected from the machine body.

Immediately you need to unscrew and disconnect the pump - it is in order, it will still serve. Be careful with the terminals, they are fragile and can be damaged! The remains of the housing with screws are removed, the spring clamps are pressed out and the pipes are disconnected.

It is necessary to remember which of the rubber pipes leads where, since for an untrained person they are all the same.

ABOUT

Often it is possible to completely disconnect the filter with the pump, but the cover still does not unscrew.

In such situations, you can try to disconnect the filter from the pump, clean it from the inside and soak the housing in a basin or bucket.

Take warm water, dissolve liquid soap or washing powder in it and leave the body for several hours. Fatty deposits and dirt will become wet and fall away from the inner surface of the lid. Now you can try again to unscrew it in the usual way.

Replacing the snail

The washing machine pump (pump or “snail”) sooner or later fails. In addition, when removing a soured filter, it is easy to damage the pump, which will require replacing the entire assembly.

The procedure is simple if the old filter and pump are already disconnected and turned off. The main problem is to find suitable replacement elements.

Then all actions will consist of sequential installation of the filter and pump in their standard places in the machine body.

Folk remedies for caring for the unit

Let's look at the main products used to clean the drain filter and how to use them. These are proven effective methods that you can use to prevent and clean filters using simple DIY methods.

Application of citric acid

Citric acid is an affordable and cheap product that is odorless.

You should not overuse citric acid or use it at high temperatures, as it can damage plastic elements.

Rules for using lemon:

Pour 60-100 grams of acid into the powder container. The amount of product is determined by the length of time during which no cleaning was carried out.
Turn on the device for a full cycle at a temperature of 60 degrees or more. The maximum temperature mode is chosen if the machine is heavily dirty.
Remove dirt and acid residues by rinsing. If the machine is not completely cleaned, repeat the procedure.

Upon completion, the filter is cleaned of any remaining deposits.

The process of cleaning a washing machine using citric acid is demonstrated in the video:

Cleaning the filter with soda

Baking soda is an affordable solution for cleaning mold. Soda is used to clean all parts on which it forms.

Mode of application:

Soda is diluted one to one with water.
The fabric is moistened in a solution of water and soda.
Use a soaked cloth to wipe moldy elements.
After several hours, the wash is started.
At the end of it, remove any remaining dirt manually.

The procedure can be repeated several times, depending on the degree of contamination.

Using table vinegar

When using it, not only mold and scale are removed, but also an unpleasant odor.

Mode of application:

200 ml of 9% vinegar is poured into the powder tray.
Turn on washing at temperatures from 60 to 90 degrees.
After filling the machine with hot water, pause for 1 hour.
Continue washing until complete.
Clean the filter from remaining contaminants.

Then wipe all surfaces with a clean, dry cloth and allow to dry.

Whiteness in the fight for purity

The product can be classified as both professional and home use. Simple and affordable, it has a pungent odor. Provides high-quality cleaning of the drain filter.

Method of use:

White is poured into the container for filling the powder.
Turn on the longest cycle with the highest temperature for 15–20 minutes, pause the machine and leave for 2 hours.
Includes washing and rinsing.
Start the rinse cycle again.

Finally, wipe the parts dry with a rag.

Use of copper sulfate

This is an excellent, easy to use, affordable, odorless product.

Copper sulfate is an absolutely harmless anti-fungal remedy for machine parts. It can be purchased at a hardware store or market for summer residents

Instructions for use:

The powdered substance (30 g) is diluted in 1 liter of water.
Wipe all the insides of the car and leave it for a day.
Start the wash with any washing powder.

As in other cases, turn on the additional rinsing program, and after cleaning, wipe with a dry cloth.

If you don’t want to do the “dirty” work yourself, you can call a plumber. Professional cleaning will eliminate the need to do work that is unusual for you.

Part selection

If you cannot do without replacing the hose, you need to make the right choice. Possible options:

Standard. Its length can be 1-5 m. This is enough to connect an LG washing machine to the sewer drain in a regular bathroom.
Telescopic. When compressed, it is 50 cm; if it is expanded, the length will increase to 150 cm. This is a practical solution, since the length of the tube can be adjusted.
However, when fully stretched under strong water pressure, it will vibrate violently.
Bulk. It is represented by several modules, the size of which is 50-55 cm.

For most models of LG washing machines, a hose with an outer hole diameter of 27 mm and an inner hole of 21 mm is suitable. To accurately determine the size, you need to know the SMA brand. You can find out more information in the user manual.

If it is not possible to purchase an original, then before purchasing you need to take measurements of the old part . This will allow you to make your choice.
