Have you noticed that your washing machine has started making a suspiciously loud hum, grinding noise or knocking noise during the spin cycle? This symptom is one of the most common among household appliances, and it is dangerous to ignore it. The noise is not just annoying: it signals a malfunction that can lead to serious damage if you do not intervene in time.
In this article we will look at all possible causes of a hum during spinning - from a banal imbalance of linen to wear of bearings that require replacement. You will learn how to diagnose the problem yourself, what tools you will need for repairs, and in which cases it is better to call a specialist. And we will also give step-by-step instructions with photos and videosso that you can cope without extra costs.
Important: some faults (for example, bearing failure) develop gradually. If today the car is just loud, then in a month it may stop completely. Therefore, we need to act now.
1. Linen imbalance is the most common cause of humming.
Let's start with the simplest and most harmless problem: uneven distribution of laundry in the drum. When things clump together (such as large towels or blankets), the center of gravity shifts. During the spin cycle, the drum begins to hit the housing, producing a loud knocking or hum.
How to check? Stop the wash and distribute the laundry manually along the sides of the drum. If after restarting the noise disappears, the problem is solved. If not, move on.
- ๐งบ Overload by weight: Exceeding the maximum load (usually 5โ7 kg for most models). Check the instructions for your Samsung WW6000 or LG F12A8NDS โ the exact limit is indicated there.
- ๐งฆ Too little laundry: 1-2 items (such as one T-shirt) can also cause imbalance. Add a few more items.
- ๐งถ Rolling the fabric: Down jackets, blankets or woolen items often bunch up. Use special laundry bags.
If imbalance occurs regularly, check shock absorbers - they may be worn out. We will talk about this in one of the following sections.
2. Wear or damage to bearings - serious damage
If the spin noise is accompanied by metallic grinding or vibration that is transmitted to the floor, with a 90% probability they are to blame drum bearings. This malfunction requires immediate attention, as it can lead to tank destruction and costly repairs.
How to diagnose:
- Open the hatch and rotate the drum by hand. If you hear a crunch or play (the drum wobbles), the bearings are worn out.
- Start the wash without laundry on a spin program. A hum without load is a sure sign.
- โ๏ธ Reason #1: natural wear (bearing life is 5โ10 years).
- ๐ง Reason #2: water ingress due to a damaged oil seal.
- ๐ง Reason #3: factory defect (found in budget models Indesit or Ariston).
What happens if the bearings are not replaced?
Over time, they will completely break down, and the fragments can damage the tank, engine or belt. In the worst case, the machine will fail, and repairs will cost 70โ80% of the cost of new equipment.
Replacing bearings is a complex procedure that requires disassembling the machine. If you are not confident in your abilities, it is better to contact the service. Average repair cost: 3,000โ8,000 rubles (depending on model).
3. Problems with shock absorbers and springs
Shock absorbers and springs dampen drum vibrations during spinning. If they are worn out or broken, the car begins to โjumpโ and the noise intensifies. This is especially noticeable at high speeds (1000+ rpm).
How to check shock absorbers:
- Open the top or back cover of the machine (depending on the model).
- Find shock absorbers (usually 2-4 pieces, located at the bottom of the tank).
- Press the tank with your hand: if it drops and rises easily without resistance, the shock absorbers are faulty.
| Symptom | Probable Cause | Remedy |
|---|---|---|
| The car "jumps" on the floor | Broken 1-2 shock absorbers | Replacing a pair of shock absorbers (cost: 800โ2000 rubles) |
| Rumble + knocking noise when spinning | Springs have weakened or burst | Tighten or replace springs (RUB 500โ1,500) |
| Vibration even at low speeds | Wear of all shock absorbers | Complete replacement of the kit (RUB 2,000โ4,000) |
To replace shock absorbers you will need:
- ๐ง Set of screwdrivers (phillips, flat).
- ๐จ Wrenches (usually 8โ10 mm).
- ๐ ๏ธ New shock absorbers (select by car model).
โ๏ธ Preparation for replacing shock absorbers
4. Motor or belt malfunction
If the hum is accompanied buzzing or whistling, the problem may lie in electric motor or drive belt. These elements are responsible for the rotation of the drum, and their breakdown leads to unstable operation.
Signs of engine trouble:
- ๐ The hum becomes louder over time.
- ๐ฅ Smell of burning (burnt winding insulation).
- โก The machine suddenly turns off during a spin cycle.
How to check the belt:
- Remove the back cover of the machine.
- Inspect the belt for cracks, splits, or looseness.
- If the belt slips, it needs to be tightened or replaced.
Before replacing the belt, take a photo of its position on the pulley - this will help you install the new one correctly.
Cost of a new belt: 500โ1500 rubles. Replacing the engine will cost more - 5,000โ15,000 rubles, depending on the model (Bosch WLG20260, Electrolux EWS1066 etc.).
5. Foreign objects in the drum or tank
Sometimes the cause of the hum is small items, caught between the drum and the tank: coins, buttons, bra wires or even children's toys. They get stuck in the drain pump or rub against the walls, creating noise.
How to remove a foreign object:
- Check the hatch cuff - often small things get stuck in its folds.
- Tilt the car back and look under the drum (you'll need a flashlight).
- If the object is stuck deep, remove the heating element (heating element) and remove it through the hole.
Never try to reach an object with your hand through the hatch while the machine is running - this is dangerous! Always turn off the power before inspection.
If you suspect that a large object (such as a key or phone) is stuck in the tank, it is better to call a professional. Removing it yourself may damage the tank.
6. Failure of the drain pump (pump)
The drain pump removes water from the machine before spinning. If it is clogged or broken, the machine will buzz and vibratetrying to drain the water. Sometimes this is accompanied by errors on the display (for example, E21 at Samsung or F03 at Indesit).
How to clean the pump:
- Open the bottom panel of the machine (usually it is secured with latches).
- Place a water container and unscrew the pump filter (turn counterclockwise).
- Remove debris (hair, threads, coins) and rinse the filter under water.
If the pump does not work even after cleaning, it will have to be replaced. Average cost of a new pump: 1,500โ4,000 rubles.
7. Incorrect installation of the machine
Even a new washing machine can hum when spinning if it incorrectly installed. Common mistakes:
- ๐ Uneven floor: The car rocks and the vibrations increase.
- ๐ฉ Legs not adjusted: at least one leg does not touch the floor.
- ๐งฑ Coating too soft (carpet, linoleum without a rigid base).
How to fix:
- Use a building level to level the car.
- Adjust the legs with a wrench (they should be screwed all the way, but not skewed).
- If the floor is uneven, place the machine on anti-slip mat or a special stand.
After adjusting the feet, check the machine idle: run the spin cycle without laundry. If the vibration disappears, the problem is solved.
8. Wear of motor brushes
In cars with commutator motors (installed on most models Indesit, Ariston, Candy) graphite brushes wear out over time. This leads to:
- ๐ Increased hum during spin cycles.
- โก Sparking inside the engine.
- ๐ Sudden car stops.
How to check brushes:
- Remove the back cover of the machine.
- Find the engine and unscrew its mounts.
- Remove the brushes and evaluate their length: if they are shorter than 1.5 cm, they need to be replaced.
Cost of new brushes: 300โ1,000 rubles. Replacement takes 30โ60 minutes and does not require special skills.
FAQ: Frequently asked questions about the hum of a washing machine
Is it possible to use the machine if it makes a humming sound when spinning?
If the hum is caused by an imbalance or a small object in the drum, yes, but it is better to eliminate the cause. If the problem is in the bearings or motor, Every wash makes the damage worse. and can lead to costly repairs.
How much does it cost to replace bearings in a washing machine?
The cost depends on the model:
- Budget cars (Indesit, Ariston): 3,000โ5,000 rub.
- Middle class (Samsung, LG): 5,000โ8,000 rub.

The price includes labor and spare parts.
How often should the drain pump be cleaned?
It is recommended to clean the pump filter once every 3โ6 months, depending on the intensity of use. If there are animals in the house or you wash woolen items, cleaning should be done more often.
Is it possible to replace shock absorbers yourself?
Yes, if you have basic tool skills. The main thing is do not mix up old and new shock absorbers (they may differ in hardness). Also, don't forget to unplug your machine before starting work!
Why does a new machine hum when spinning?
Possible reasons:
- The transport bolts have not been removed (they secure the drum during transport).
- The machine is installed on an uneven floor.
- Factory defect (rare, but occurs in models Beko or Vestel).
Check the drum mountings and level the machine.
If after checking all the points the hum does not disappear, contact the service center. Perhaps the problem lies in electronics (for example, a faulty control module) or mechanical damage that is not visible during a superficial inspection.
Remember: timely diagnostics saves up to 70% of repair costs. Don't delay - deal with the noise today!
