Almost everyone who uses a washing machine is aware of its habit of bouncing and leaving its place during the spin cycle. This article will discuss the causes of the phenomenon and methods for their prevention.
First, consider the reasons. They can be divided into two groups:
- factors causing vibration of the washing machine;
- factors allowing the vibrating machine to move across the floor.
Why is the washing machine jumping?
The first cause of strong machine vibrations may be unmounted shipping bolts. They fixedly fix the washing machine tank inside the casing so as not to damage it during transportation. Before starting work, bolts and other locking elements must be removed. It is strictly forbidden to operate the machine with them.
The next cause of vibration of the washing machine is uneven distribution of things in the tank. If you start the machine with an empty tank, it will not vibrate. The same thing happens if you distribute things perfectly evenly - evenly over the entire circumference of the tank. In reality, such a distribution is impossible to achieve, even evenly distributed at the beginning, are mixed during the washing process.
Faulty tank suspension and pillow block bearings. Loose counterweight.
The purpose of the system of springs, dampers and a counterweight is to make the frequency of natural oscillations of the tank much lower than the frequency of its rotation. This reduces the amplitude of the vibrations and the magnitude of the vibrations transmitted to the machine body.
To better understand the contents of the previous paragraph, remember: at the beginning of the spin, the case of the loaded machine sways harder, and then with an increase in the speed of rotation of the tank, the buildup goes into a small shiver or, with the correct distribution of linen, practically disappears.
Pump the tank - after that it should make no more than one oscillation and stop. Otherwise, shock absorbers are defective, they must be replaced.
Open the casing of the machine, inspect the elastic elements - metal ones should not have deformations, rubber ones - no tears and cracking. Defective parts - under replacement! Check counterweight mounting - if loose, tighten nuts.
Defective bearings. When the machine is running, there should be no creaks and knocks. Turn the tank manually, swing from side to side. If squeaking or beating occurs, replace the defective parts.
Proper installation of the washing machine
First requirement to install - horizontal floor. When deviating from the horizontal, the vibrating machine will slide in the direction of the slope. If the floor is imperfect, you need to build some kind of podium that creates a horizontal surface for the machine. At the same time, he himself should not slip on the surface of the floor.
Second requirement - horizontal machine itself. Or verticality. It depends on what is chosen as a criterion: the upper plane should be strictly horizontal, any side edge should be vertical.
Why is this needed? With the most careful distribution of things, they will shift during the washing process and create a heartbeat when the tank rotates quickly. In an uneven machine, the beats deviate from the calculated ones and, as a result of an uneven load on the supports, can cause displacement.
Is the effect of deviation significant? It’s better not to analyze, but simply set the car up to the level. This is not such a difficult operation.
How to set the car in level? What do you need to adjust?
Before starting work, prepare a level approximately 1 meter long. No longer needed. If there is no such long, take what is. But we must keep in mind that the shorter the level, the less accuracy.
You will also need two open-end wrenches. The size should correspond to the adjusting nuts on the legs of the machine.
Step-by-step instructions for installing the washing machine
Checking for horizontal platformon which the device will stand. The horizontalness of the entire site is not important, but the plane passing through the heels on which the legs of the machine will rest.
We check the level of the platform horizontally on both diagonals. If horizontality is observed here, check along two adjacent sides. If everything is in order here, we put the car with its legs on the tested sites. If the floor is not horizontal in any directions, put stands on low places, achieving horizontalness in all directions.
Stands can be made from any flat and hard material. On the side in contact with the floor, it is recommended to stick a thin sheet of rubber. About his appointment will be written below.
Now we put the washing machine on the platform or on the stands. By adjusting the height of the legs, we achieve horizontal top surface. We check the correct installation of the vertical edges of the side ribs.
If everything is fine, tighten the locknuts on the adjusting screws of the legs and check once again whether the verticality and horizontalness were violated during the lockout.
Now try to shake the car left and right and diagonally. If it doesn’t swing, it’s not almost, but it doesn’t swing at all - that means the car is set up correctly.
But there is one more nuance. As already noted, it is almost impossible to completely eliminate vibration, so there is always the possibility of the washing machine leaving its rightful place.
Remember, a sheet of rubber was glued to the stands for the legs? This is so that with small vibrations they do not slip on the floor and prevent the machine from moving.
Find a rectangular sheet of rubber 1-1.5 cm thick and about 5 cm larger than the size of the machine. The hardness should be such that the legs miss it about half the thickness. Place it on a horizontal surface under the machine, and the chance of leaving will decrease to zero.
Tips for using the machine to reduce vibration.
Do not overload the machine. The suspension system is designed to work with a certain load. Exceeding will lead to excessive vibrations, and in the long run to premature failure of nodes.
Before starting, distribute things evenly around the circumference of the drum. There are machines that can do this on their own, but still help them - artificial intelligence is not so smart yet.
If your machine is horizontally loaded, you can hold something heavy on it, such as a laundry basket. This will increase vibration resistance.
Position the machine at least 5 cm from the walls so that in case of an emergency it does not damage them and herself.
In the end, we briefly list what was discussed in the article:
- Do not forgetRemove the transport bolts;
- The machine must be onhorizontal surface;
- The machine must stand strictlyupright;
- Place a rubber mat under the legs;
- Evenly distribute things around the circumference of the drum;
- Do not overload a car;
- Provide a gap between the wall and the machinenot less than 5 cm;
- Attention! Never use a malfunctioning machine. If the elastic element breaks off on the fly or the bearing scatters, the breakdown can reach such proportions that the extra washed shirt will turn out to be gold.
