✅ Why does the washing machine drum knock during the spin cycle

Published: 14 Oct 2020

Although advertising promises with all its might that the washing machine operates silently, in reality this is not the case. SMA is a complex household appliance, some of its parts move and rotate, and therefore make noise. This is the sound of normal operation, but sometimes owners notice that something is knocking loudly inside the washing machine. It can rattle in different ways:

a knocking sound appears during washing or is heard during the spin cycle of the washing machine;
The knocking sound in the washing machine is heard only in the spin mode.

What to do if you hear unusual knocking sounds? First you need to exclude external causes.

The washing machine knocks when washing and spinning

If your washing machine is knocking, there may be several reasons for this knocking: improper installation of the machine itself, problems with one of the counterweights, a loose power filter, a slipped shock absorber or a broken spring, foreign objects between the drum and the tub, as well as problems with bearings.

First of all, before you panic, take a close look at the laundry in the washing machine. It happens that during the washing process, laundry rolls up into one laundry ball. This happens especially often when you wash a set of bed linen, and the duvet cover serves as an excellent environment for the formation of this lump. In this case, during the spin cycle, the washing machine jumps, jumping and moving all the built-in equipment in the neighborhood.

If there are no problems with the laundry, but there is still a knocking noise, then to figure out exactly why the washing machine is knocking and what to do about it, read below.

Prevention

In order for the machine to serve as long as possible, you should take small precautions:

Items with small parts that can come off during washing are best washed in a special bag;
Before placing things in the tank, you should check their pockets for debris, small items and other items that could damage the drum;
do not exceed the load of the washing tank, observe the restrictions;
add special substances that soften water - they will help preserve the heating element and remove scale;
the machine must stand level and secure;
It is advisable to ventilate the internal elements of the device, for which you need to open the hatch for loading laundry and the tray for detergents.

For more information about the causes and repair of a washing machine that is knocking, see below.

Make sure the machine is level

If the machine's legs are not level, it will begin to shake and knock during the spin cycle. To fix the problem:

Make sure the machine is on a level surface. It often happens that one leg ends up in the groove between the tiles or stands on the baseboard. Move the machine so that it is on a level surface.

Move the machine away from the wall and tilt it so that the front legs are visible. Have someone hold the machine, otherwise you will not be able to do the following steps, or place a block of wood under it. Be careful not to touch wires or cables.

Make sure the legs are the same length. You can use a ruler, measuring tape, or tape. Measure the height to the nearest millimeter - even a small difference in the legs will lead to significant swaying and knocking. If the legs are the same length, make sure they fit snugly on the floor.

If the legs are of different lengths, adjust them in height. To do this, it is enough to simply twirl them by hand. But in most machines they are fastened with a nut, which must be loosened with a wrench in order to shorten or lengthen the legs. Make sure you screw the nut back to adjust the height. Alternatively, you can place a folded piece of paper or a piece of carpet under the shorter legs.

If you still can’t balance the machine, you can place special rubber vibration absorbers under the legs, sold in hardware stores.

Of course, you can also use a building level by placing it on the top of the washing machine. But this may not work if the floor is on a slope. So first check the levelness of the floor using the same building level.

What causes the vibration?

Everyone knows that top-loading washing machines are much quieter than front-loading washing machines. Why? Yes, because when the drum of a front-loading washing machine rotates, centrifugal force presses on the side walls, rocking the body. And the faster the drum rotates and the more laundry there is, the stronger the impact of centrifugal force and, accordingly, the more sensitive the vibration. Everything would be fine if vibration did not have a comprehensive harmful effect:

it destroys machine parts, gradually rendering it inoperable;
it is accompanied by a hum and rumble, which can be unpleasant not only to the owners, but also to the neighbors;
it has a negative impact on the flooring and nearby furniture.

There have been cases when, due to the vibration of a working washing machine, glasses and plates flew off the countertop under which it was installed onto the floor and were broken into pieces.

In general, vibration during the spin cycle of a Samsung washing machine, or any other one, is an inevitable evil that you have to put up with. It’s okay, if the vibration occurs slightly during operation of the machine, it is within normal limits. In principle, no one suffers from such an impact, but what if the vibration is strong, and even accompanied by loud unnatural noises? Now is the time to sound the alarm and see what could potentially cause such a problem. The options are as follows:

the machine is installed on an extremely unstable piece of furniture or flooring;
things were loaded into the car incorrectly;
they forgot to unscrew the shipping bolts, but started the machine;
a foreign object got into the tank of the Samsung washing machine;
the bearings were seriously damaged or completely destroyed;
one of the dampers broke;
the counterweight has been destroyed or displaced.

Installation in violation of the rules

Experts never tire of repeating that the washing machine must be leveled on a stable, hard surface. It is not necessary for such a surface to be perfectly flat, because small differences can be compensated for by twisting the legs. But it must be as strong as possible so that it does not bend, sway or even creak under the weight of an adult man.

When installing a washing machine, you cannot part with the building level. Place a level on the lid of the washer and check it every time you tighten the legs of the “home assistant”. It has been proven that even slight distortions of the body in one direction or another have an impact later, significantly increasing the vibration of the Samsung washing machine during spinning.

Before using your new washing machine, be sure to remove the shipping bolts. Otherwise, you not only risk damaging the drum of the new machine, you also doom yourself to listen to the clanging and feel the monstrous vibration at the moment when the machine starts spinning the laundry at a speed of over 1000 rpm. You can read more about installation rules in the article Installing and connecting a washing machine.

Operational errors

Vibration during spinning can also occur if you use your Samsung washing machine incorrectly. What seems absolutely unimportant to you may ultimately play a fatal role. What is it about?

First, pay attention to how you fold the laundry into the drum of your Samsung washing machine. You cannot lump up a large number of things or one bulky item. Dirty laundry must be evenly distributed in the drum, otherwise there will be an imbalance and, as a result, strong vibration.

Secondly, before putting things into the drum, check their pockets to ensure that foreign objects do not get stuck in the tank and cause loud noises and vibrations. Thirdly, put all things potentially dangerous for the washing machine in a washing bag, and only then put them in the drum of the Samsung washing machine. There have been cases when a bra wire got stuck in the tub of a washing machine and jammed the drum for some time, causing clanging and strong vibration.

Everything could have ended even worse, because the metal wire from the bra is quite sharp, and the wall of the tank is made of plastic. There have been cases when such a bone pierced the wall of the tank, breaking its tightness.

Bearings and dampers

All of the above can be called minor troubles that can be eliminated in a matter of minutes.
But it happens that vibration and strong, unnatural sounds during spinning are caused by a serious breakdown or manufacturing defect. In essence, we are talking about only two failures: bearing failures and damper failures. You can change the damper yourself; just remove the back wall of the Samsung washing machine and we will have access to the broken part and its fasteners. At least, if we can’t repair it, then at least we can change it.

Article on the topic: How to clean a washing machine with citric acid and soda

For those who don’t know, a damper is a part similar to a shock absorber that performs its functions.

With bearings the situation is much more complicated. To change them, you will have to disassemble the entire washing machine, including the tank. If you are an experienced DIYer who is not afraid of manual labor, go ahead and try changing the bearings with your own hands, our publication will help you. If you are not used to repairing equipment yourself, it would be better to contact a specialist.

In conclusion, we note that a slight vibration emanating from a Samsung washing machine during spinning is quite normal. But if the washer starts to shake very strongly, you need to look for the cause of the problem. It is possible that you are dealing with a serious malfunction. Luck with searching!

Malfunction related to counterweight

The washing machine may also knock due to a faulty counterweight. A counterweight is a special weight that is fixed at the bottom inside the machine body. It consists of concrete and is necessary in order to dampen the vibration of the machine during spinning and other operations. During prolonged use, the fixation may become loose. Therefore, the counterweight may come into contact with the housing, causing a knock. This often happens during the process of squeezing out the laundry.

If the whole point is a weak fastening, then you just need to tighten the bolts properly. But if, upon opening the body of the machine, you see a broken or broken counterweight, then tightening the bolts is not enough. To solve this problem, you need to order a new counterweight and replace the one that broke.

It makes a lot of noise - is this a breakdown or normal?

During operation of the device, noise may sometimes even be a normal situation. Some sounds that Indesit makes are not a sign of failure.

Such situations include noise during the following processes:

water inlet;
pump operation;
heating water;
rotation of the drum during the spin process;
clattering transition to a new stage of the washing program.

You should start to worry when the car suddenly starts making strange sounds that are not typical for it. Most often, they make themselves felt precisely when the drum is actively rotating and under high load. If there is noise in the device, it is important to correctly determine its cause.

In some cases, such a sign is not a breakdown. Each device has a maximum permissible noise value .

This indicator is indicated in the documents for the machine. Typically this is between 60 dB and 72 dB. If during operation the noise level is within the limits specified by the manufacturer, this is not a malfunction, but corresponds to normal operation.

The washing machine drum is knocking

The knocking of the washing machine drum during spinning or during washing can be caused by two reasons:

Article on the topic: How to integrate a washing machine into a kitchen set photo

Debris got into the space between the drum and the tank - during the washing process, a bra bone, coins, paper clips or other small parts that you tried to remove from your pockets could get into the drum of the washing machine. These parts can penetrate the gap between the cuff and the drum and enter the tank. During washing, they are in the space between the poppy and the drum and are constantly in contact with both, which causes knocking.

In order to remove the items, you will have to remove the front or back cover of the washing machine (depending on the model) and remove the heating element. Through the hole that appeared in place of the heating element, you can remove all excess debris.

The second reason for the knocking of the washing machine drum can be wear of the bearings ; usually the knocking is also accompanied by a squeaking sound.
More often than not, creaking precedes knocking, so if you understand that this is the reason, then you should replace the bearings, you can read how to do this on our website. Why.

Our operator received a call:

— My washing machine constantly tries to escape from the bathroom, as if it doesn’t like the place! She shakes, jumps, stubbornly moves towards the exit from the bathroom, and she has to be driven back almost with a kick. No, well, that's normal. Let your specialist come and do something about it! — Apparently, your machine hasn’t liked living in the bathroom since its purchase. - Yes, but over the years she breaks free more and more persistently. Sometimes she gets so angry that you have to hold her down with your hands! Maybe let him run to the trash heap under his own power; I’ll buy a new car - more flexible and not so capricious. “Everything is just like people: with age they become grouchier and grumpier!” But unlike old people, who are unlikely to be corrected, things are much better with washing machines.

Essentially, this is a disease of almost all narrow (33-45 cm deep) washing machines, regardless of the manufacturer. There is very little space inside the machine body, and the existing counterweights (obviously insufficient) cannot dampen the vibration that occurs during spinning, when the drum reaches maximum speed. The reason for this is the laundry, which is distributed unevenly along the walls and shifts the center of gravity of the drum, causing strong vibrations.

Engineers, of course, know about this, and therefore they long ago came up with the idea of hanging the tank on spring mechanisms designed to compensate for vibration. And, I must say, this works on wide washing machines, but the trick didn’t work on narrow ones - they still jump like mountain sheep.

But if you happen to be the owner of such a “beast,” do not despair ahead of time. Manufacturers seemed to come to their senses and, realizing their shortcoming, released special stands for the legs of the washing machine, made of soft plastic and ensuring a tight fit (and even sticking) to the floor surface, and with the other side - reliable fixation to the legs. This helped: now the machine stops moving chaotically around the room.

So, we have dealt with one reason, our washing machine repair technicians believe that several more reasons can be eliminated without their help: 1. Eliminate unbalanced laundry. 2. Tighten loose counterweight fastenings. 3. Check the engine mounting. 4. Make sure that the shipping bolts have been removed, otherwise unscrew them.

However, there are a number of reasons that cause noise, hum, vibration, knocking and even thunder in washing machines, which have nothing to do with mountain goats and airplanes, which can only be eliminated by specialists: 1. Faulty, cracked shock absorbers of the washing machine. 2. Broken washing machine tank suspension spring. 3. Mechanical damage to the counterweight. 4. Wear and play of bearings.

When the knocking is not associated with a breakdown

Sometimes the sound does not come from inside the washer. The cause of noise is in the environment or external elements of the SMA.

The machine is close to furniture or a wall. According to the installation rules, there must be a gap between the case and adjacent objects if the equipment is not built-in. When everything is standing end to end, due to vibration, the SMA can knock on the surface nearby. Move the equipment aside or place a shock absorber between the body and the wall. For example, a rubber or foam seal with an adhesive backing.
The washing machine hose is knocking . Another source of sound is the drain hose. If it is poorly secured and loose, it can knock on the body of the washer. Check the hose and secure it tightly to the body.

Sometimes it rattles inside the machine, but the reason is not in it, but in the laundry.

Clothes fittings are knocking. There are metal or plastic parts on clothes: zippers, buttons, trim. Such items need to be turned inside out or placed in a washing bag in the machine so that the hard parts do not touch the drum and rattle. In addition to the fact that the fittings are noisy, they can damage the drum, the repair of which is expensive.

Have you checked how the machine is installed, secured the hose, did not wash items with hard fittings, but the knocking does not stop? This means it’s time to call a repairman; the cause of the suspicious sounds, unfortunately, is related to a breakdown.

Unevenly distributed laundry

This problem is typical for older models. Modern devices practically do not rattle, of course, if they are in good working order and installed correctly. Good alignment is facilitated by the presence of electronics, which allows you to distribute things more evenly and prevent imbalance in the drum. Old devices cannot assess how well the drum is centered, and whether there are crumpled laundry in it. Spinning occurs in any case, and then the drum may knock on the walls or other elements of the washing machine.

The main causes of breakdowns due to knocking and grinding of the washing machine

A number of malfunctions may be accompanied by unusual sounds.

Only a washing machine repair technician can determine the exact picture when diagnosing the equipment using special equipment.

The main causes of knocking, noise, and grinding of washing machines are typical for most manufacturers.

Washing machine drum knocks during spin cycle

If the drum of the washing machine knocks during the spin cycle, it means there is a foreign object in the cavity between the drum and the tank of the appliance. Small items from pockets, torn buttons, or other small parts can make a knocking noise.

You cannot operate the washing machine when the drum is knocking during washing and spinning! It is necessary to eliminate the interference, otherwise the drum may jam and the problem will worsen.

Another reason may be hidden in the surge protector, if the mounting bolts have been unscrewed and it has moved away from the mounting location. The job of a surge protector is to regulate the voltage during sudden surges. A loose filter hits the body of the washer when the drum rotates, creating a knocking noise.

You just need to fix the filter or change the fastenings.

The washing machine squeaks when the drum rotates

If the washing machine squeaks when the drum rotates, there can be many explanations for this unpleasant phenomenon, for example:

when rotating, rusted bearings make a sound;
hairs or lint from washed linen and clothes have stuck to the cuff of the hatch;
The drive belt is loose and slipping;
the fastening holding the drum shaft has become loose;
the springs holding the tank are worn out;
small items of clothing have fallen between the tank and the drum, for example: socks, a scarf;
the drum mount is unbalanced and it rubs against the body;
The walls of the case creak due to poor-quality fastening.

Each of these breakdowns requires a more thorough study and intervention by a specialist.

The washing machine rattles during the spin cycle and vibrates

During the spin cycle, the washing machine rattles and vibrates when problems arise with the balancing stone, which serves as a counterweight and smoothes out the vibration.

The problem makes itself felt when the counterweight is loosened or the stone begins to collapse and, instead of balance, rocks the car even more to the sides. The malfunction is considered quite rare and can be solved by adjusting the mounting bolts or replacing the damaged counterweight.

Crackling sound in the washing machine when the drum rotates

A cracking sound in the washing machine when the drum rotates can be caused by failed shock absorbers. Stretched shock absorber springs or the springs themselves make a rattling sound when the machine is running; when the drum rotates, you can clearly hear something cracking.

An imbalance occurs and the drum will lean to one side, hitting the body and adjacent parts of the MCA.

Shock absorbers cannot be repaired; they must be replaced, both at once. By changing only one shock absorber, you do not allow the load in the car to be distributed evenly. Be prepared for the second one to fail very soon.

The springs are located under the tank at the bottom of the car; from constant moisture they become covered with rust and become unusable.

The drum in the washing machine is loose

A slight loosening of the drum is provided for by the design of the washing machine.

If the drum in the washing machine is loose and this is accompanied by the following symptoms, then a technician is needed to fix the problem:

the operation of the machine is accompanied by a roar during spinning, noise and creaking when the drum rotates;
the drum wobbles and hits the body and the glass of the door during the spin cycle;
the machine jumps and vibrates significantly in the “spin” mode;
The drive belt constantly falls off;
the drum rubs against the rubber cuff;
below, under the SMA, on the tank, dark oily or rusty streaks are visible;
the machine “chews” the laundry, and it is stained with rust or oil;
the drum of the machine is skewed;
if the plugs are knocked out, smoke may come out of the SMA;
the drum becomes wedged and a metallic grinding sound is heard when rotating;
the drum flew off the mount and fell.

Article on the topic: How to clean a washing machine with citric acid and soda

All of the above symptoms indicate failure of the following parts: shock absorbers, oil seal and bearings, cross shaft, one or all springs.

An experienced technician can figure out why the drum is loose and easily replace the unusable part.

The washing machine drum knocks when it picks up speed

If the washing machine drum is knocking, especially when it picks up speed, and this is not due to incorrect installation and uneven placement of laundry in the machine, then the problem may be the following:

one of the springs on which the drum is attached can fly off, burst, or stretch, as a result the drum with the counterweight tilts in one direction and the drum can knock heavily at high speeds;
The mains filter has become loose and is touching other parts; a knocking sound is especially audible when the drum picks up speed;
The ballast (counterweight) has become loose and at speed, instead of smoothing out the vibration, it increases its vibration.

It is quite difficult to figure out any of the described situations yourself, especially to make repairs without the necessary knowledge, since all breakdowns are similar to each other and the malfunction of one part leads to the unsuitability of others.

Diagnostics

To fix a problem, you must first identify it. Correct diagnosis is half of a successful repair. Before contacting a service center, some faults can be determined independently.

If you hear a knocking sound when the drum rotates, it is most likely that change has fallen out of your pocket or the clothing has not been turned inside out so that the buttons and zippers are turned inward.
If you hear a strong squeaking sound when the car picks up speed, it is likely that the bearing is worn out. To check this version, you need to open the hatch of the washing machine, press on the inner edges of the drum and scroll. Some skipping and cracking may be felt. It is likely that the bearing is faulty.
Sometimes you can hear a knock on the case during operation. A possible cause is an imbalance in the rotation axis. To exclude or confirm this breakdown, you need to check the drum play: if it is too large, then this is the problem.
If the machine begins to make a lot of noise and vibrate, then the counterweight mounts may have become loose.
When you open the door, you can see that the tank is slightly tilted. When you press it, it hits the walls or other parts of the machine.
If the washer made a very loud noise while draining the water and stopped working, then most likely the pump has broken down.
To identify the incorrect installation of the machine, you just need to press one of its corners - it should not swing. You can also check it with a building level.

Causes of drum knocking in a washing machine

The most common causes are the following problems:

In first place in terms of frequency will be incorrect installation of the machine, the most easily eliminated and most common operating defect. It is quite easy to determine that this is the problem: visually inspect how the machine is installed on the surface, and if the angle of inclination to one side is too large, start calibrating the location by tightening the wheels - legs. For a better effect, you can use a level. If you cannot visually determine whether the machine is level, you need to pay attention to the operation: if the drum is positioned incorrectly, it hits the sides of the body at maximum washing speed, which creates unnecessary knocking.

Washing machine counterweights

You need to pay attention to exactly when the drum begins to make noise.

An imbalance has occurred

If the drum makes a knocking sound when rotating, it may be due to an imbalance. When a small load of clothes or one large item is loaded for washing, during the process they clump and fall to one side. Therefore, the drum begins to knock against the walls of the tank, which leads to extraneous sounds.

You can solve the problem like this:

Stop the cycle or pause it. If there is water inside the washer, drain it.
To drain, open the small hatch - it is located below, under the front panel.
Unscrew the filter, placing a container to collect water.
After unlocking the hatch, open the door and use your hands to arrange the laundry evenly.

A problem such as imbalance is typical for older washing machines. Because in new models, manufacturers have provided the “Imbalance Protection” function.

The washing machine was installed incorrectly

In this case, the drum knocks when it picks up speed - for example, during a spin cycle. At the same time, a strong vibration is felt, the entire structure rattles. How to check if the installation was carried out correctly:

Place a level on the SM body.
Shake the body with your hands. If it wobbles and the legs come off the floor, then the problem is due to incorrect installation.

The machine should stand on a flat surface, the legs should be in close contact with the floor. If you cannot place the legs level, use silicone pads, which can be bought in stores.

Foreign object hit

What are the signs that there is an object in the drum:

The washing machine drum made a loud noise when washing and spinning.
When spinning the drum by hand, an extraneous sound is heard: noise, ringing and knocking.

Article on the topic: Why the hotpoint-ariston washing machine does not turn on

If, even after clearing the laundry, something rattles in the drum, a coin or button may have gotten in, or debris from your pockets may have clogged up. You cannot let things take their course, otherwise this may lead to jamming of the drum.

You can remove the item by bending the hatch cuff or pulling out the heating element. In difficult cases, you will have to remove the tank from the housing.

A detached surge protector exhibits the same symptoms.

Since the filter is attached to the rear wall of the SMA housing, it constantly hits the tank during operation.

To correct the situation, you need to remove the top cover. To do this, unscrew the two screws on the back, slide the cover away from you and remove it from the case. Check the filter fastenings: if they are in order, secure the filter in place. If they are broken, replace them.

Bearings are worn out

What else can cause a car to squeak when cranking? Grinding and noise indicate bearing wear. And if you hear that the MMA is humming and whistling, this means that the bearings are already reaching their expiration date and need to be replaced urgently.

How to verify a malfunction without disassembling the washing machine:

Rotate the drum by hand; if uneven rotation is noticeable, the bearing has begun to wear out.
Rock the drum up and down with your hand. If it moves so far away from the tank that a play (hole) is formed, then the bearing is about to fail.

Replacing a bearing in a drum is an inexpensive but time-consuming repair. But if the replacement is not made in time, this will lead to damage to the tank and crosspiece. As a result, it will be cheaper to buy a new washing machine.

To replace the bearing, you need to purchase a repair kit and completely disassemble the machine to remove the tank with the drum. If your car is squeaking, get it done as soon as possible.

The counterweight is loose

Since the tank itself is light, counterweights are used to weigh it down, ensure uniform rotation, and dampen vibration. If the counterweight is loose and loose, you will hear a clattering noise and feel a lot of vibration.

How to adjust the counterweight:

Remove the front panel of the washer. Typically two counterweights are mounted on the front wall of the tank.
After removing the top cover, pull out the dispenser tray by pressing the latch in the center.
Remove the bolts that secure the control panel.
Release the plastic latches using a flathead screwdriver.
Detach the control panel and place it on the chassis.
Remove the plinth panel. Now you have access to the front panel fastenings.
Unscrew all the bolts around the perimeter and remove the front panel.

Check the counterweights and secure their fastenings. If one of the counterweights is destroyed (this is rare, but happens with concrete stones), you need to replace it with a new part.
