What to Do If the Washing Machine Is Too Noisy?

Washing machines can make different sounds depending on the operating stage. The noise level may change while filling with water, draining, and especially as the drum speed increases during the spin cycle. However, if there is a loud knocking, rumbling, friction, rattling, or strong vibration that was not there before, the cause of the problem must be investigated.

If the washing machine is too noisy, the cause is not always a serious technical malfunction. Simple reasons such as the machine not being installed level, uneven distribution of the load in the drum, or failure to remove transport bolts can also cause loud noise and vibration. In other cases, internal parts such as shock absorbers, bearings, belts, pumps, or balance weights need to be checked.

This article is for informational purposes. The initial inspection steps here refer to simple diagnostics that the user can safely perform. It is safer to consult the model manual and a qualified technician for dismantling internal parts, interfering with electrical components, and replacing mechanical parts.

What is the normal sound of a washing machine?

A washing machine is not expected to run completely silently. Water flowing during filling, the operation of the drain pump, the hum of the motor, and the increase in speed during the spin cycle can create a certain amount of noise. Samsung also states that a hum-like sound during spinning in a properly functioning machine can be normal, but knocking, squeaking, rumbling, and other extraneous noises should be investigated.

The following distinction is useful for initial diagnostics:

Whether the sound occurs only during spinning, only while draining water, or throughout the entire program also helps to determine the cause.

Why is the washing machine so noisy?

What happens if the transport bolts are not removed?

In new washing machines, transport or shipping bolts are installed to keep the drum stable during transport. These bolts must be removed before the machine is used. If the bolts are left in place, the drum cannot move normally, and strong vibration and noise occur, especially during spinning.

This problem should be considered especially if the machine has just been purchased and installed.

What can be done?

1. Stop the machine and unplug it.

2. Check the transport bolts on the back panel.

3. Compare whether the bolts have been removed with the user manual.

4. Remove the bolts as indicated in the model's manual.

5. Insert the protective caps provided in the manual into the bolt holes.

6. Check the machine again.

If it is not possible to remove the bolts or you are not sure which part is the transport element, it is better to contact service instead of using force. LG states that failure to remove transport bolts can cause strong vibration and noise, and even damage the device.

What to do if the machine is not placed on a flat surface?

All feet of the washing machine must be in firm contact with the floor. If the machine is tilted or one of the feet is not fully seated on the floor, vibration increases as the drum spins at high speed.

Check procedure:

1. Make sure the machine is unplugged.

2. Check the machine by gently rocking it side-to-side and diagonally.

3. If the machine rocks, adjust the level of the feet.

4. Make sure all four feet are in firm contact with the floor.

5. If there are locking nuts, tighten them after adjustment.

6. Check the vibration with a short test program.

LG recommends checking the level in both front-to-back and side-to-side directions, ensuring all feet are firmly on the floor. If the floor itself is flexible or unstable, adjusting the feet alone may not be enough.

How does an unbalanced load cause noise?

If the washing machine is very noisy during spinning, one of the simplest possibilities is that the clothes have gathered on one side of the drum. Especially washing a single heavy item, a large towel, a duvet, or a fabric that absorbs a lot of water can disrupt the balance of the load.

What can be done?

1. Stop the machine and wait for the program to stop safely.

2. Check if the clothes have gathered on one side.

3. Distribute heavy and large items evenly in the drum.

4. If you have overloaded the machine, remove some of it.

5. If washing a single heavy item, balance the load according to the model's manual.

6. Restart the spin program.

Whirlpool and Samsung note that an unbalanced and overloaded drum can cause vibration and noise.

What to do if there is a foreign object in the drum?

Coins, buttons, metal parts, hard plastic objects, and other small items left in pockets can create knocking, rattling, and friction sounds when the drum rotates. Samsung also lists foreign objects and metal parts as causes of noise.

To check:

1. Turn off the machine and unplug it.

2. Rotate the drum slowly by hand.

3. Check if there is a foreign object inside the drum.

4. Also check the folds of the door seal.

5. Check the pockets of clothes in advance for the next wash.

If an object is stuck between the drum and the tub and does not come out by hand, do not try to dismantle the machine's housing.

Why does noise increase if shock absorbers are worn out?

Shock absorbers or dampers are suspension parts that help keep the drum's movement under control. Especially in front-loading models, weakening or damage to the shock absorber can cause the drum to move excessively during spinning and hit the housing.

In this situation, the machine can vibrate strongly not only with one load but also with various loads. In technical repair sources, worn shock absorbers are listed among the causes of continuous vibration and impact sounds.

What can be done initially?

• Check the load balance.

• Check the machine's level.

• Make sure the transport bolts are removed.

• If strong impact and vibration continue when these problems are not present, have the shock absorbers checked by service.

Since the replacement of shock absorbers varies by model, it is not recommended to perform this work without experience.

What sound is created if bearings are worn out?

Bearings play an important role in the rotation of the drum. Their wear can create a continuous hum, rumble, or friction sound, especially during high-speed spinning.

If the sound repeats regardless of the amount of laundry and increases especially as the spin speed increases, the possibility of a bearing problem should be considered. Bosch and technical repair sources state that continuous rumbling or knocking can be related to drum bearings and suspension parts.

What can the user do in this case?

In addition to simple external checks, it can be observed whether there is unusual play or mechanical noise in the movement of the drum. However, dismantling and replacing the bearing is a complex repair job. If the sound is continuous, especially if it gets louder, service diagnostics are necessary.

Can the drive belt or strap cause a problem?

In belt-driven washing machines, loosening, wear, or damage to the drive belt can cause unusual noise during rotation. This problem does not apply to all models, as some modern machines use different motor transmission systems.

The possibility of a belt-related problem can be considered especially when the sound occurs along with the rotation of the drum and difficulty in the machine reaching normal speed is observed. Technical repair sources list a loose or damaged belt as one of the possible causes of unusual noise.

Since dismantling the housing and replacing the belt depends on the model, it is more appropriate to contact service for this work.

What happens if the balance weights are loose?

In washing machines, heavy balance weights or counterweights help reduce the movement of the tub and vibration. If the fastening of these parts becomes loose or the mounting element is damaged, strong impact and knocking can occur during spinning.

If the machine is on a flat surface, the load is placed correctly, and the transport bolts are removed, but strong impact sounds continue in various programs, internal fasteners and balance weights should be checked. In technical service sources, loose balance weights are listed among the possible causes of heavy impact and vibration.

Since these parts are heavy, it is not recommended for the user to perform their fastening on their own.

How to prevent washing machine noise?

To prevent loud noise, it is not necessary to take action only after a malfunction occurs. Proper installation and following usage rules are also important.

• Install the machine on a hard, flat, and stable surface.

• Make sure all four feet are in firm contact with the floor.

• Remove transport bolts before installing a new machine.

• Do not overload the machine.

• Avoid washing single heavy items in an unsuitable program.

• Check pockets before washing.

• Prevent coins, keys, and other hard objects from falling into the drum.

• Check that the inlet and drain hoses are not touching the housing and creating noise.

• Keep the filter clean according to the manufacturer's recommendation.

• Do not allow the sides of the machine to touch walls or furniture.

• If unusual noise becomes persistent, do not delay the problem.

Manufacturers like Samsung and Whirlpool consider proper leveling, balanced load, proper installation, and sufficient space around the machine important for reducing vibration and noise.

When should the washing machine be shown to a technician urgently?

In some cases, it is not right to continue using the machine. If one of the following signs is present, it is safer to stop the device and get service diagnostics:

• If there is a smell of burning or melted plastic;

• if smoke or sparks are observed;

• if a strong metal friction or grinding sound occurs;

• if serious play is felt in the movement of the drum;

• if the machine slides significantly from its place during spinning;

• if the housing moves with strong impacts;

• if there is continuous strong vibration even with a normal load;

• if the sound repeats in every wash program;

• if water leakage occurs along with the sound;

• if the machine shows an error code and noise is also observed.

Especially in case of a burning smell, smoke, and suspicious situations related to electricity, the device should not be restarted. Bosch also recommends getting professional help if strong and unusual noise continues after initial checks, especially if there is a possibility related to bearings, suspension, motor, and transmission parts.

Frequently Asked Questions

Why is the washing machine so noisy during spinning?

The most common causes are unbalanced load, the machine not being level, overloading, and failure to remove transport bolts. If these are normal, the shock absorber and other mechanical parts should be checked.

If the washing machine is newly purchased and is very noisy, what could be the reason?

First of all, it is necessary to check whether the transport bolts have been removed and whether the machine is properly leveled. Strong vibration in a newly installed device can be related to these reasons.

If the washing machine makes a rumbling sound when spinning, could the bearing be broken?

Yes, continuous rumbling and mechanical noise that gets louder especially as the spin speed increases can be related to bearing wear. However, the same symptom can also occur in other mechanical problems. Service inspection is necessary for an accurate diagnosis.

What should be done if the washing machine moves from its place?

First, check that the machine is on a flat surface and that all feet are in firm contact with the floor. Then make sure the load is evenly distributed in the drum. If the problem persists, the shock absorber and other suspension parts should be checked.

What should be done if there is a knocking sound from the washing machine?

First, check for coins and other items left in pockets, foreign objects in the drum, and also uneven loading of clothes. If the sound continues after these are eliminated, there may be a problem with internal mechanical parts.

Conclusion

If the washing machine is too noisy, it is not right to immediately assess the cause as a serious malfunction. First of all, it is necessary to check the installation of the machine, transport bolts, load balance, and whether there are foreign objects in the drum. If the noise continues after these simple causes are eliminated, the technical condition of the mechanical parts should be investigated.

Continuous rumbling may indicate bearings, strong impacts may indicate shock absorbers or balance weights, and unusual sounds during rotation may indicate belts and other mechanical components. Since the diagnostics and replacement of these parts depend on the model, it is safer to consult a qualified technician.

The most correct approach is to determine not only how loud the sound is, but when and in what form it occurs. Thus, it is easier to distinguish a simple installation and loading problem from a serious technical malfunction.
