The quiet and stable operation of washing machines is important both for the health of the device and the comfort of the user. However, in some cases, the machine may operate loudly, which not only causes discomfort but also indicates the presence of a technical malfunction inside the device. Such noises can stem from various causes, each having a different technical explanation. Identifying the source of the noise in time can not only ensure the longevity of the device but also prevent major malfunctions. Let’s explain together the six main problems that cause washing machines to operate noisily and determine in which cases technical intervention is required.

1. Incorrect Installation and Balance Issues

Improper leveling and placement of the washing machine on an unstable surface is one of the most common reasons for noisy operation. If the legs of the machine are not adjusted or tightened, vibration and loud noise may be observed during washing. The balance issue becomes especially apparent during the spin cycle, as the drum rotates at higher speeds. If the device is placed on a soft or slanted surface instead of a solid one, this also increases vibration. If one leg is higher or lower than the others, it causes the machine to tilt and operate unbalanced. If the imbalance continues for a long time, it may affect internal parts and lead to the failure of shock absorbers and bearings. To solve this problem, the level on which the machine is placed should be checked with special tools, and the legs should be made even. Also, care should be taken to ensure that there are no cushions, carpets, or other soft materials under the machine. Thanks to such simple measures, the noise problem can be significantly reduced, and the device will operate more stably.

2. Items or Small Objects Left Inside the Drum

One of the factors that cause noise in a washing machine is small items forgotten in the pockets of clothes. Coins, buttons, hair clips, keys, or other metal and hard materials spin inside the drum during washing, hitting other parts and creating disturbing noises. These objects mostly fall into the gaps between the drum and the metal walls and get stuck there. As a result, friction and impact sounds occur. The repeated hitting of small objects against rotating parts also increases the risk of damaging the internal components of the machine. Even after prolonged exposure, the inner parts of the drum and plastic components may be scratched or punctured. This type of noise not only causes discomfort but also leads to potential repair costs. Therefore, it is important to carefully check the pockets before placing clothes into the machine. Forgotten items are especially common in children’s clothing and jeans. If metallic impact noises are heard during washing, it is recommended to stop the machine immediately and remove such objects from inside.

3. Wear and Malfunction of Bearings

Bearings are important technical components that maintain the stability of the washing machine’s drum and allow it to rotate smoothly and quietly. These parts naturally wear out when the machine is used for a long time, which can eventually cause them to lose their functionality. Worn bearings produce metal friction and squeaking-like noises during the rotation of the drum. Although this sound may initially be faint, over time it intensifies and can reach a level that disrupts the machine’s operation. Bearing malfunction can also cause the device to vibrate and even move from its place. If the problem is caused by the bearing, only an experienced technician can replace it, as several internal components of the machine need to be disassembled to do so. Failure to address the issue in time may also result in damage to the drum, motor, and other essential parts. Increased friction also raises energy consumption and reduces the efficiency of the device. For this reason, if there is an abnormal sound coming from the drum, it is recommended to seek technical inspection rather than continuing to operate the device.

4. Malfunction in the Shock Absorber and Spring System

Shock absorbers and springs are critical components that minimize the vibration of the washing machine, ensuring that the device operates stably and quietly. These parts, usually located at the bottom of the machine, cushion the movement of the drum and prevent shaking. However, over time and with continuous use, shock absorbers may lose their elasticity and wear out. When this happens, especially during the spin cycle, strong vibrations and noises occur in the machine. The instability in the drum’s movement leads to increased noise and causes the machine to operate unbalanced. Damaged shock absorbers not only result in disturbing sounds but also impair the overall functionality of the device, potentially damaging other mechanical components. The machine moving or even jumping from its place is an indicator of this malfunction. If the issue is not resolved in time, the drum may hit the frame, causing additional mechanical damage. Therefore, the condition of the shock absorbers and springs should be regularly checked during technical maintenance and replaced immediately if any malfunction is detected. This way, both the noise problem is eliminated and the device’s lifespan is extended.

5. Electrical Motor and Belt Issues

The electric motor, considered the heart of the washing machine, is the main mechanism that enables the rotation of the drum. If a technical malfunction occurs in this motor, squeaking, humming, or high-pitched spinning sounds may be heard during operation. Such noises are mostly related to the wear and tear of internal components such as bearings and carbon brushes within the motor. On the other hand, loosening, tearing, or slipping of the belt connecting the motor to the drum can also create similar sound effects. Reduced belt tension makes the rotation unstable and sometimes causes the drum to move with sudden jerks. This process puts additional strain on both the motor and the drum, leading to the malfunction of the overall mechanism. During high-speed cycles, noise caused by belt issues increases and irritating intermittent humming sounds may be heard. To prevent this problem, the motor and belt components should be inspected during technical maintenance and replaced if necessary. Although the belt is a simple and inexpensive part, its proper functioning is essential for the stable movement of the entire system.

6. Contact of Foreign Objects with Rotating Parts

One of the reasons disrupting the quiet operation of a washing machine is the contact of foreign objects with rotating parts. Sometimes items that fall around or under the machine, such as pens, spoons, toy parts, or metal objects, get stuck in the rotating parts and cause noise. Such objects typically enter through the machine’s ventilation openings or from the back section. When the device starts operating, these objects touch the drum or motor components, causing mechanical impacts. As a result, repetitive, rubbing, or knocking sounds may be heard. If this problem is not resolved in time, the objects may damage the rotating parts or even cause the motor or arms to fail. Some foreign items may get stuck inside the device, leading to serious technical malfunctions. Therefore, ensuring a clean environment and removing any surrounding items before the machine operates is important. If the noise comes from inside the machine, turning it off and conducting a visual inspection can help identify the source. However, if you’re not sure, it is safer to seek professional assistance.
