LG washing machine does not drain or spin

If the LG washing machine does not drain water or spin clothes, what can be done in this situation? Users who mercilessly exploit their Korean home assistant may one day encounter such a problem. You can immediately call a specialist and this will be the most correct decision. But if you have the time and desire to figure out the problem yourself, take note of the information we present in this publication.

What caused the breakdown?

A specialist, relying on his experience, is able to quickly determine the reason why the LG washing machine does not want to drain and spin clothes, and then quickly fix the breakdown. It is much more difficult for the average user to do this, primarily due to the lack of experience and relevant skills in working with equipment, but if you show patience and spare no effort and time, everything will work out. First you need to decide on an algorithm for finding a breakdown.

  • First, we check for dirt plugs and stuck objects: garbage filter, pipes and pump.
  • Then we look at the pump in more detail for mechanical and electrical breakdowns.
  • Next, remove the pressure switch and check whether it is clogged, and then test the water level sensor using a multimeter.
  • Lastly, we check all the wiring inside the body of the LG washing machine and the control module.

By following this plan, you will most likely be able to detect a malfunction. But as they say, remember to keep your eyes open and notice any oddities when disassembling your washing machine. In this case, you will more likely gain experience and be able to solve this and other problems, because this is not the first and not the last time equipment breaks down.

The car is clogged with dirt

Most often, the LG washing machine stops spinning and draining water not even because of dirt blockages, but because foreign objects get into the pipe or garbage filter. Even if a foreign object does not immediately plug the drain path, over time small debris will settle on it and the partial blockage will turn into a solid plug through which water will barely seep through.

The drainage path of the LG washing machine is made in such a way that 90% of foreign objects that accidentally get there settle on or near the garbage filter. This is a huge plus, because getting to the garbage filter is incomparably easier than getting to any other internal parts of a Korean washing machine. Let's start with the filter.

  • In the lower right corner of the LG washing machine, find the small plastic cover and open it.
  • Under the lid you will see a large black plug, next to which sticks out a small hose plugged with a plug.
  • Place a shallow container under the hose to drain any water remaining in the tank. This is done like this: open the cap, fill the container, close the cap, pour the water out of the container, and then fill the container again until all the water has been removed from the tank.
  • Unscrew the garbage filter. You need to turn it to the left half a turn, and then pull it towards you. If you haven’t pulled out the filter for a long time, it may stick, but this is not critical, pull harder and it will pop out.
  • Inspect the filter itself and the hole you removed it from. Pull out any foreign objects and dirt that are stuck there. Often, when cleaning the filter, users pull out stuck things: socks, bra wires, coins, paper clips, pins, buttons, swimming trunks and much more.

If you find something like this in the garbage filter, consider the problem of difficult draining solved. But if the filter turns out to be clean, or almost clean, and there is nothing stuck there, the search must be continued.

Drain pump faulty

In the next step of the inspection, we will continue to look for blockages in the washing machine. To do this, we will inspect the pipes, drain hose and, of course, the pump. We will focus on the drain pump, since it really needs to be checked with all possible care. We unplug the power cord of the washing machine from the outlet, turn off the water, disconnect the inlet and drain hoses, and then carefully pull out the washing machine to a place where it will be more or less convenient to work with it. Next we do the following.

  • Remove and put aside the powder tray.
  • Carefully, without sudden movements, place the washing machine on its left side.
  • Having gained partial access to the insides of the LG washing machine through the bottom, we loosen and move down the clamps securing the drain pipe coming from the tank.
  • We remove the pipe and see if anything foreign is stuck there.
  • We clean and rinse the pipe, then put it in place.
  • Next, disconnect the drain hose and check it for blockages.
  • Lastly, unscrew the pump mount and remove it to check.

To begin with, the pump body is disassembled into two halves and the impeller is inspected for contamination. You can often find wound threads, human hair, and even scraps of thin fabric on the impeller. All this makes it difficult or impossible to rotate this moving part, which means the pump simply stops functioning. If the impeller rotates normally and nothing foreign is wound on it, it is necessary to check the functionality of the electrical part of the pump.

This is not difficult to do. We take a device called a multimeter. We turn its toggle switch, setting the resistance test mode. Let's start checking. If, as a result, the device shows a large number, then the problem is not with the pump; if the numbers 1 or 0 are displayed, the situation is bad, the pump must be replaced.

Level sensor or control module?

Washing things in an LG automatic washing machine is impossible if the water level sensor is malfunctioning, and if the sensor is completely burned out, then this is a problem that requires immediate resolution. To check the water level sensor, you need to find it. This is not difficult to do; you first need to remove the top cover of the LG washing machine. Under it, in the right front corner of the case, right behind the panel, you will see a chip-shaped round thing with a sensor attached to it - this is the pressure switch.

We will not separately describe the process of dismantling and checking it, since we have already done this as part of the article The spinning and draining of water in a Samsung washing machine does not work . In LG washing machines, the pressure switch is removed and checked in the same way.

If everything is fine with the water level sensor, but the LG washing machine still does not drain the water and does not spin things out, this most likely means a breakdown of the electronics, specifically the control module. There are more than enough reasons why the electronics of a washing machine breaks down:

  • Various types of power failures,
  • Poor-quality soldering of board tracks,
  • Moisture entering the electronic module,
  • User errors, etc.

Whatever the cause of the breakdown, it is better not to look for it yourself. Even if you have experience working with electronics, the risk of breaking an expensive part is too great. For our part, we cannot advise you to repair the module yourself - contact professionals!

To summarize, we note that if your LG washing machine refuses to drain water after washing and does not spin clothes, you can try to cope with the problem yourself, but remember, if the malfunction has affected the electronic part of the home assistant, it is better to delegate the repair to a specialist.
