Causes of noise in washing machines
In normal operation, the noise level of new devices is low. Compliance with the rules of installation and placement allows you to minimize its intensity. Increased or atypical sound means a breakdown of one of the nodes and the need for repairs.
Rotation of the drum during the work and an extraction
The main “classic” sound of a washing machine comes from a rotating drum and partly from a motor. It is uniform, monotonous, characterized by a smooth increase and decrease in strength. The rumble is made by things in contact with the drum and with each other and water. Modern engines (especially inverter) are virtually silent.
Information about the maximum value of sound is given in the technical documentation. As a rule, the manufacturer indicates two values: during washing and during spinning at maximum speed. Modern devices usually fit the volume of 55 and 77 decibels, respectively.
For each model, the parameters for loading laundry are defined. If you do not comply with them, there will be a bias in the placement of things inside the drum, which will cause vibration and noise during washing.
Many manufacturers provide the ability to program the spin mode with turns less than the maximum. This leads to more residual moisture, but less damage to things and reduces the sound of a working device.
Design changes in motors and drives also contribute to quieter work. First of all, the sound level was positively influenced by the rejection of the belt connection in favor of the direct drive coupling. It should also be noted that the new inverter motors are much quieter than the collector ones. They are almost not audible against the background of noise from the loaded drum.
The worn-out shock absorbers contribute to the increase in the noise level during the work of the washer:
If wear is detected, the cushioning devices should be replaced.
Like any dynamic parts, the shaft (axis) of the drum and the bearing wear out or deform over time. In this case, the smoothness of the stroke is disturbed and, with rotation, the whistling tone begins to be traced in the published sound spectrum. The noise level becomes uneven, and its strength begins to pulsate at intervals of 1 to 3 seconds.
If you experience these symptoms, you must eliminate the cause of the problem. Seizure of the bearing at full speed can cause such severe mechanical damage that the repair of the machine would be inappropriate.
If a sound is unusual for a washing machine, you should immediately look for the cause. Otherwise, a minor problem can cause serious damage.
Other sources of loud sound
Often, increased noise occurs when draining or typing water. Most users who write about the high level of sound in the reviews to washing machines, This is believed to be due to a pump malfunction or constructive errors during its operation. designing. However, this happens more often for other reasons:
- Inflection causing a reduction in hose cross-section. Leads to the creation of a vacuum zone when the pump is running. Forced aspiration of air is the cause of gurgling sounds.
- The presence of a local maximum area at the water supply hose. It accumulates air, forming a bubble. The effort of the pump will be enough to push it through, but when starting work, a loud gurgling sound arises.
- A blockage that occurs either in the water supply hose itself. Or a similar situation may occur in the area of its connection with the water supply system. This reduces the water pressure below the permissible, which is specified in the technical documentation.
- Overpressure When water is drained due to high pressure, loud noises from diverting pipes or sewage arise. This problem occurs when they are clogged or initially lacking bandwidth. Washing machine is nothing to do with.
The next possible problem is vibration. It occurs when the mass distribution inside the rotating drum is uneven. The counterweight system partially compensates for the imbalance of centrifugal force, and the shock absorbers create an inertial component, which, summing up the vector of forces of the opposite direction, practically stops the transfer of oscillation energy to case.
Objects placed on the washing machine start moving with the slightest vibration. Therefore, do not place solid objects on the machine, as they will generate sound during washing.
However, even in serviceable devices, a slight vibration does exist. It is therefore necessary when choosing a location for the machine to provide a gap between it and other hard objects, such as sink, bathroom, wall, etc. If the open space is undesirable, it can be filled with foam, closing the top with soft rubber or polyurethane foam inset.
If suddenly the washing noise increased significantly, the vibration appeared stronger than usual, it is necessary to stop the process. Most likely, there were mechanical problems in the system of counterweights, shock absorbers, or in the region of the central axis of the drum. Before proceeding, you need to find and fix the problem, otherwise there may be a serious breakdown.
If a rattling or knocking sound is heard, then this may be due to a foreign object falling into the niche between the drum and the body. It is necessary to stop the washing process and find the source of the sound. Most likely, this is a nut or a screw. We need to find a place where it fell from, and restore the integrity of the mount.
When installing the washing machine, a common mistake is to misalign it. To achieve a more accurate position, you must use a level. Twisting the legs must be performed diagonally: for example, set the near right and the far left legs, having achieved a horizontal position diagonally, and only then adjust the position of the rest legs.
If the legs of the washing machine were lost or broken, then anti-vibration mats can be used. They are made of foamed rubber, have a good grip, so they will not move even on slippery linoleum
Another reason may be uncleared bolts fixing the position of the tank, which is used when transporting the device from the store to the consumer. Although modern washing machines are triggered by the protection system when trying to start the device when the shock absorbers are locked.
The monotonous sound of any adequate volume will not cause waking of small children. But the electronics signals the completion of the work can wake the child. Therefore, you need to find ways to reduce their volume or turn it off completely.
Rules for calculating the integral indicator
To avoid subjective assessments in the preparation of the rating, a calculation formula was developed:
R = (A1 + 2 * A2* (Owed / O)) / k
- R is the calculated noise factor: the smaller it is, the quieter the device works;
- A1 - the noise level during washing;
- A2 - the noise level during spinning, taken with a multiplying factor “2”, since it is at this stage that the machine makes the sound of maximum power;
- Owed - average median value of the maximum spin speed among the models under consideration (equal to 1200 rpm for both types of machines);
- O - maximum spin speed of a specific model;
- K is a reduction factor.
Combined coefficient “Owed / O ”, with reference to the noise level during the spin cycle, is taken from the considerations that with the same sound power indicator, a model with higher revs should receive a higher place in the rating.
This is true if we consider the following example. Suppose two models have the same level of noise when spinning, but the machine “A” has a maximum value of 1200 revolutions per minute, and the device “B” - 1400. Then it is logical to assume that, for example, with a delicate wash with a spin speed of 800 rpm, the washing machine “B” will be quieter.
Virtually all modern models allow for a decrease in spin speed. This not only helps to preserve the integrity of the laundry, but also reduces the sound level.
The coefficient “K” is initially equal to “1”. If it is possible for the user to reduce the spin speed (there is a shutdown for all models), he is assigned the value “1.1”. If there are options that have a positive effect on the noise level, the value “0.1” is added for each of them, but no more than two times for one model. Thus, K lies in the range [1,0; 1.3].
Frontal washing machine rating
For 15 popular manufacturers, an up-to-date integral rating has been compiled, reflecting the noisiness of their washing machines.
Brands are ranked based on the declared sound power at different cycles, the possibility of reducing the maximum speed, as well as the presence of functionality aimed at achieving silence during operation. For the analysis, only the latest models with almost the same permissible load value of dry laundry (6-8 kg) were taken.

Conclusions and useful video on the topic
Noise insulation of a washing machine with the help of pasting sound-absorbing material on the inside of the walls and panels:
Installation of anti-vibration pads to reduce noise and stabilize the washing machine:
All washing machines generate sound during operation. Its greatest force occurs during the spin cycle, when the drum rotates at maximum speed. The noise figure is not the main selection criterion; however, the rating given makes it possible to give an objective assessment of the manufacturers and their models from the position of ensuring sound comfort.
