There’s more to this knocking sound your LG washing machine makes during the spin cycle than just annoyance. This problem might indicate a more serious one that requires care. When you hear strange noises coming from your washing machine, it’s time to investigate. A properly functioning washing machine should operate smoothly and quietly.
A knocking drum can have a number of reasons, from small problems like laundry slopped unevenly to more significant mechanical issues. Addressing the noise as soon as possible is crucial because ignoring it could cause more harm.
We’ll go over the most frequent causes of your LG washing machine’s drum knocking during the spin cycle in this article. In addition, we’ll offer advice on how to pinpoint the problem and workable fixes to get your machine operating smoothly and silently once more.
Your LG washing machine’s drum may be knocking during the spin cycle. This could be the result of an uneven load, loose parts, or worn bearings. If you take care of these problems right away, you can keep your machine from getting worse and maintain its smooth operation.

Most likely, this is not a breakdown
If the washing machine started to "jump" around the room and knock loudly, it is safer to stop the cycle abruptly and give the machine a thorough inspection. Knocking can result from multiple issues at once, such as a blockage, defective shock absorption, or broken bearings. In any event, the container "flies off" and strikes the washing machine’s body, upsetting the drum’s equilibrium.
Not all imbalances result from malfunctions; frequently, users’ casual inattention is the cause of the issue. First, you need to rule out pointless reasons so that you don’t disassemble the machine in vain. We are discussing the instability of the equipment and incorrect loading of the drum.
- Loading standards were not met. The main reason for the imbalance is exceeding the maximum capacity of the machine. The same outcome occurs when the cylinder is not filled enough. In any case, you will have to stop the program, open the hatch, and then add or take out some of the laundry.
The system of contemporary LG washing machines guards against imbalance; if it is detected, the wash is stopped and the associated error code is shown on the display!
- The laundry is unevenly distributed. Often the machine knocks due to "clumping": the clothes loaded into the drum gather into one lump. The balance is disturbed, the cylinder shifts from the specified trajectory and hits the side walls of the machine. The problem is solved simply: just pause the cycle, open the hatch door, take them out, straighten them out, return them and continue washing.
- The machine is not level. The washing machine must stand on a flat and hard surface, otherwise imbalance and knocking are inevitable.
Using a building level, the washing machine’s stability is examined. The equipment must be moved to a more level surface or the leg heights must be adjusted if the device displays abnormalities. You can attempt to swing the machine to test it out for yourself. When installed correctly, a unit won’t move.
Shock-absorbing system
The shock-absorbing system, which consists of dampers and springs, is what reduces vibrations in LG washing machines. They allow the machine to stay balanced even when it is spinning at its fastest. The balance is upset when the shock-absorbing components wear out or break. The drum moves and strikes the housing walls, causing a knock and a hum to appear.
A washing machine with inadequate shock absorption carries a significant risk of internal damage, making it unsafe to use. When the first knocks occur, it is preferable to inspect the machine’s dampers and springs and replace them with new ones if necessary. The steps are as follows:
- de-energize the machine;
- remove the top cover by unscrewing the corresponding bolts;
- raise the washing tank to the maximum height;
- fix the new position of the tank with a hard object, for example, a bar;
- pull the spring towards you and unhook it;
- install a new element.
Replacement parts are chosen based on the LG washing machine model’s serial number.
Once the repair is finished, lower the tank into position and replace the top cover. Then, we initiate a test wash and connect the apparatus to communications. The troubleshooting process continues if the washing machine continues to rattle.
The counterweight is damaged or destroyed
The washing machine has the necessary stability thanks to counterweights. These are blocks of concrete, and the weight of them dampens the centrifugal force coming from the drum. Beneath the housing’s upper cover are stones that are fastened with stronger bolts. Because of all of this, the machine can spin and wash without rattling or bouncing.
Disconnecting the LG washing machine from communications is necessary prior to performing diagnostics and repairs.
The counterweights become less securely fastened over time; the bolts become loosened and the nuts come loose. Consequently, the blocks become loose and do not dampen vibration; rather, as they spin, they collide with the machine’s walls. It is required to tighten the fasteners in the following manner in order to solve the issue:
- de-energize the equipment;
- remove the top cover;
- inspect the blocks;
- tighten the washers.
In order to strengthen the structure, extra washers must be added to the bolts if "tightening" the fasteners does not help. The unit will be secured more securely in this manner.
| Issue | Possible Cause |
| Drum Knocking During Spin | Unbalanced Load: The washing machine might have an uneven load. Try redistributing the clothes inside the drum. |
| Drum Bearing Wear | The drum bearings might be worn out or damaged. A technician may need to replace them. |
| Suspension Springs Issue | The suspension springs could be broken or loose. This can cause the drum to move excessively. Check the springs and replace if necessary. |
| Foreign Object | Small items like coins or buttons might have gotten stuck between the drum and the drum basket. Inspect and remove any foreign objects. |
| Damaged Drum | The drum itself might be cracked or damaged. This requires professional repair or replacement. |
Something is definitely wrong if the drum of your LG washing machine is knocking while the machine is in the spin cycle. It could indicate more significant issues that require attention, even though it might just be a small problem like an uneven load.
You can avoid more serious headaches in the future by taking the time to diagnose the problem. Early problem solving is crucial, whether it involves changing the load, ensuring that the machine is level, or examining components like the shock absorbers or drum bearings.
Recall that keeping your washing machine in good working order can be greatly aided by routine maintenance. If you try to stop the knocking but it keeps happening, it might be a good idea to get professional advice to avoid more harm.
