LG washing machine does not drain water: 7 reasons and what to do

Washing machine LG Has the water stopped draining after washing? This is one of the most common malfunctions that equipment owners encounter. The problem can manifest itself in different ways: water remains in the drum after the end of the program, the machine freezes at the draining stage or gives an error OE (drain fault code LG). In most cases, you can fix the breakdown yourself without resorting to expensive repairs.

In this article we will look at all possible reasonsaccording to which the washing machine LG does not drain water - from a clogged filter to a pump breakdown. You will receive step by step instructions on diagnostics and repair, as well as tips on how to avoid repeated failures. If your model is equipped with a display, pay attention to the error code - this will significantly narrow down the search for the problem. For owners of cars without a screen, we have prepared universal verification methods.

Before proceeding with repairs, make sure that the problem is not due to a temporary glitch. Try it restart the machine: unplug it for 10-15 minutes, then plug it back in and run the drain program (usually indicated as Spin or Drain). If this doesn't help, read on.

1. Clogged drain pump filter is the most common cause.

In 70% of cases the culprit is that the washing machine LG does not drain the water, it becomes clogged pump filter. It is located in the lower part of the case (usually under the decorative panel) and traps debris: threads, coins, buttons, hair and even small parts of clothing. Over time, the filter becomes clogged and water cannot pass through it.

To check and clean the filter:

• 🔧 Unplug the machine and turn off the water supply.
• 📦 Place a rag or a low tray under the machine - when opening the filter, up to 1 liter of water can spill out.
• 🔄 Gently turn the filter cap counterclockwise (on some models LG it is secured with a latch).
• 🧹 Remove all debris from the filter and rinse it under running water. Check the hole in the body of the machine - dirt can also accumulate there.

If the filter is clean, but the water still does not drain, the problem may be clogged drain hose or pump malfunction. Before disassembling the machine further, make sure that the hose is not kinked or crushed - sometimes this blocks the outflow of water.

2. Checking the drain hose and siphon

If the filter is clean, the next weak point is drain hose. It may be pinched, twisted, or clogged with debris. On models LG with vertical loading, the hose is often located at the back; on front ones, it is usually routed down or to the side. Check:

• 🔍 Visual inspection: Are there any kinks, cracks or crushed areas on the hose?
• 💦 Patency: Disconnect the hose from the sewer and place it in a bucket. If water flows freely, the problem is in the siphon or pipes.
• 🧼 Cleaning: if the hose is clogged, rinse it under water pressure or clean it with a wire (carefully so as not to damage the walls).

Pay special attention siphon, if the hose is connected to it. Dirt, hair and grease often accumulate in the siphon elbow, blocking the drain. To clean the siphon:

1. Place the container under the sink.
2. Unscrew the bottom of the siphon and remove any accumulated debris.
3. Wash the parts and reassemble, making sure the connections are tight.

3. Malfunction of the drain pump (pump)

If the filter and hose are clean, but the washing machine LG still does not drain the water, the problem may lie in drain pump (pump). This unit is responsible for pumping water out of the tank. Signs of its breakdown:

• 🔊 The machine hums, but the water does not drain (the pump works, but does not pump).
• 🚫 An error appears on the display OE or PE (drain fault codes LG).
• 💥 Extraneous sounds (grinding, crackling) when trying to drain.

To check the pump:

1. Drain the water manually through the filter (as described above).
2. Unscrew the fastenings of the bottom panel of the machine and find the pump (usually it is located next to the filter).
3. Check that the pump impeller rotates freely. If it is blocked by debris, remove it.
4. Test the pump winding with a multimeter (resistance should be between 150–200 Ohms). If the device shows a break or short circuit, the pump must be replaced.

On models LG with direct drive (series Direct Drive) the pump often fails due to water getting into the bearings. In this case, replacement of the entire assembly is required, since repair is impractical.

How to test a pump without a multimeter?

If you don’t have a tester at hand, you can temporarily connect the pump to another power source (for example, a 12V power supply). If the impeller does not rotate or the engine does not start, the pump is faulty. Be careful: only work with the machine unplugged!

4. Damage to the pressure switch (water level sensor)

Pressostat (or water level sensor) signals the control module about the amount of water in the tank. If it fails, the machine LG may “think” that the tank is already empty and does not start draining. Or, conversely, assume that there is too much water and block the program.

Signs of a malfunctioning pressure switch:

• 💧 The machine takes in water uncontrollably or, conversely, doesn’t take it in at all.
• 🔄 The washing program gets confused, the cycle drags on.
• 🚨 Bugs LE or FE (on some models LG).

To check the pressure switch:

1. Unplug the machine.
2. Remove the top cover (unscrew the bolts from the back and slide it back).
3. Find the pressure switch - this is a small round part with a tube and wires connected.
4. Remove the tube and blow it out - if you hear a click, the sensor is working. If not, replacement is required.

You can also check the resistance of the pressure switch with a multimeter. When the pressure changes (for example, if you blow into the tube), the resistance should change. If the readings are static, the sensor is faulty.

5. Control module (electronics) failure

If all mechanical components are working properly, but the washing machine LG still does not drain the water, the problem may be control module (electronics board). This is one of the most difficult breakdowns, as it requires diagnosis using special equipment.

Signs of module failure:

• 🔢 The machine freezes at one stage of the program.
• 📛 Random errors appear on the display (for example, E1, E2).
• 🔌 The buttons do not respond to pressing, or the machine turns on every other time.

What you can do yourself:

• 🔄 Reset settings: Unplug the machine for 15–20 minutes, then turn it on again. Sometimes this helps with temporary glitches.
• 🔧 Check the board contacts: remove the top cover and make sure that all connectors are tightly connected, there are no signs of oxidation or burning.

If the reset did not help, and damaged elements are visible on the board (swollen capacitors, blackened tracks), it will have to be repaired or replaced. To do this, it is better to contact a service center LG, since independently repairing electronics without experience is fraught with even more serious breakdowns.

6. Clogged pipe between the tank and the pump

A less obvious but fairly common reason is pipe blockageconnecting the machine tank to the pump. Small objects (socks, rubber bands, coins) can get into it and block the flow of water. This problem is often accompanied by the error OE, but the filter and pump remain clean.

To check the pipe:

1. Drain the water through the filter.
2. Unscrew the fastenings of the front or bottom panel (depending on the model LG).
3. Find the nozzle - this is a flexible tube that goes from the tank to the pump. It is usually secured with clamps.
4. Loosen the clamps and remove the pipe. Check it for debris.

If a foreign object is found in the pipe, remove it and wash the pipe. When assembling, make sure that the clamps are tightened tightly - otherwise leaks may occur. On some models LG the pipe can be hard (made of plastic). In this case, it is cleaned through the filter hole or the tank is disassembled.

7. Other possible causes and prevention

If none of the above methods help, consider less obvious reasons:

Reason	Signs	Solution
Heating element malfunction	The machine does not heat the water, the program is lost	Replacing the heating element (tank disassembly required)
Engine failure	The drum does not rotate, error DE	Motor diagnostics and repair
Blockage in the sewer	Water does not come out of the machine or the sink	Cleaning pipes with a plumbing cable
Incorrect connection	Draining is very slow, no errors	Checking the slope of the hose (must be at least 60 cm from the floor)

To avoid drainage problems in the future, follow these simple rules:

• 🧺 Before washing, check your clothing pockets for small items.
• 🧼 Use special bags for washing things with buttons, zippers or rhinestones.
• 🔄 Once every 3 months, clean the filter and rinse the machine with citric acid (60 g per empty drum, program 90°C).
• 🚫 Do not overload the drum - this increases the load on the pump and shortens its service life.

Frequently asked questions about draining water in LG washing machines

❓ Why does the LG machine show the OE error, but the water drains?

Error OE means that the control module did not receive a signal about successful draining within a certain time. If the water goes away, but the error remains, the problem may be:

• faulty pressure switch (the sensor does not record the water level correctly);
• failure control module (reflashing or replacement of the board is required);
• clog pipe, which prevents the water from leaving completely.

Try resetting the error by turning off the machine for 10 minutes. If OE appears again - contact service.

❓ Is it possible to drain the water manually if the machine is frozen?

Yes, there are two ways:

1. Through the filter: Unscrew the drain pump filter (as described above) and let the water drain into a nearby container.
2. Through the emergency drain hose: on some models LG There is a thin hose with a plug next to the filter. Remove the cap, point the hose into a bucket and drain the water.

⚠️ Attention: Do not tilt the machine to drain water through the drum - this may damage the counterweights or seals.

❓ How much does it cost to replace a pump in an LG washing machine?

The cost depends on the model and region, but on average:

• Pump (pump) for LG — from 1,500 to 4,000 rubles.
• The work of a replacement technician costs from 1,000 to 2,500 rubles.

On direct drive models (Direct Drive) the pump is often assembled with a motor, so replacement is more expensive - up to 8,000–10,000 rubles.

⚠️ Attention: Prices may vary depending on the service center. Check the cost of spare parts using the VIN code of your model (located on a sticker on the back of the machine).

❓ Why doesn’t the LG machine drain the water only during the spin cycle?

If the water does not drain exactly at the spinning stage, the reasons may be the following:

• Programmed no drain mode (for example, Delicate or Wool). Check the program settings.
• Defective tachometer (drum speed sensor). The machine “thinks” that the drum is not rotating and blocks the drain.
• Problems with belt drive (on models without Direct Drive). If the belt is slipping, the control module may not issue a command to drain.

Try running the program separately Drain or Spin. If the water goes away, the problem is in the settings of the main program.

❓ How to check if the pump is working without disassembling the machine?

There are two ways without disassembling:

1. Listen to the work: When draining, a working pump emits a uniform hum. If you hear clicking, crackling or silence, the pump is faulty.
2. Check voltage: if you have a multimeter, you can measure the voltage at the pump contacts during draining (should be ~220V). No voltage indicates a problem with the module or wiring.

You can also temporarily connect the pump to another power source (for example, through a 12V power supply) to make sure it is working.
