The washing machine vibrates strongly during the spin cycle: causes and solutions

Why does a washing machine turn into a “washing tank” during the spin cycle?

You loaded the laundry, selected a program, started the wash - and suddenly at the spinning stage the machine starts jumping, rattling and “running” around the bathroom? This is not only annoying, but also dangerous: strong vibration can damage the housing, rupture hoses, or even move the equipment from its place. In 90% of cases, the problem is solved without calling a technician, but to do this you need to accurately determine its source.

Vibration during spinning is not a breakdown, but symptom. It may indicate either improper installation of the machine or wear of internal parts. For example, for models Samsung WW6000 and LG F2J5HN6S drum imbalance is often encountered due to the design of shock absorbers, and in cars Indesit IWSB 5085 vibration is often associated with weakening counterweights. In this article we will analyze all possible reasons - from banal to hidden - and provide checklists for diagnosis.

Let us warn you right away: if the machine “jumps” only with a certain type of laundry (for example, down jackets or carpets), the problem lies in incorrect loading. But if vibration occurs independently of things, you will have to dig deeper.

1. Incorrect installation: the machine is standing crookedly or on an unstable surface

The first thing to check is levelness of installation. Even a slight inclination of 2-3 degrees can lead to strong vibration when spinning at rpms above 800. Most modern machines (for example, Bosch WAN28260 or Electrolux EW6F4R46SI) are equipped with adjustable legs, but many users forget to adjust them after moving or purchasing.

How to check:

• 📏 Take a construction level and place it on top of the car body. The bubble should be strictly in the center.
• 🔧 If the car rocks when you press on the corners, twist the legs counterclockwise to raise or clockwise to lower.
• 🧱 Make sure the floor under the car is hard. Tile, laminate or concrete are ideal options. Soft-backed linoleum or wood floors can increase vibration.

Pay special attention anti-slip pads on legs. Over time, they wear off or come off, and the car begins to “drive.” In this case, you can buy new pads or use a rubber mat.

⚠️ Attention: If the machine is installed on a wooden floor (for example, in a private house), vibration can be transmitted to the joists and weaken them over time. In this case, it is recommended to reinforce the base with a sheet of plywood 18–20 mm thick.

2. Drum imbalance: overload, underload or improper distribution of laundry

The most common cause of vibration is uneven distribution of laundry in the drum. Manufacturers indicate a maximum load (for example, 6–8 kg for Samsung WW80T504DAN), but few people take into account that:

• 🧺 Overload (for example, 9 kg instead of 7) leads to the fact that the laundry bunches up and hits the walls of the drum.
• 👕 Underload (1-2 things) does not create enough counterweight, and the car begins to “jump”.
• 🧦 Mixed fabrics (for example, heavy jeans + light T-shirts) are distributed unevenly.

How to fix:

1. Stop the machine and manually distribute the laundry along the walls of the drum.
2. If the wash has already finished, start the program Rinse + Spin with the correct loading.
3. For large items (blankets, jackets), use the Delicate wash with reduced speed (max. 600–800 rpm).

In machines with function Auto Balance (for example, LG FH4G1BCS2) the drum automatically corrects the imbalance, but if the system fails, the vibration will only increase. In this case, diagnostics of the imbalance sensor is required.

3. Wear or damage to shock absorbers and springs

Shock absorbers and suspension springs dampen drum vibration. Over time, they wear out, lose rigidity or break - and the car begins to “jump” even with a slight imbalance. Symptoms of malfunction:

• 🔊 Loud knocking sound when spinning (as if something is beating inside).
• 🌀 The drum swings a lot if you pull it up or to the sides.
• 💧 Traces of oil appear under the car (if the shock absorber is torn).

How to check shock absorbers:

1. Open the top or back cover of the machine (depending on the model).
2. Find shock absorbers (usually there are 2-4 of them, attached to the tank and body).
3. Press the top of the tank and release quickly. If it “springs” for more than 1–2 seconds, the shock absorbers are worn out.

The average service life of shock absorbers is 5–7 years. In cars Indesit and Ariston they fail more often due to the use of cheap plastic bushings. Replacement will cost RUB 1,500–3,000 per pair (depending on the model).

⚠️ Attention: If the shock absorber is torn and oil is leaking from it, repairs must not be postponed! Oil can get on the electronics and cause a short circuit.

4. Loose or damaged counterweights

Counterweights are heavy concrete or plastic blocks that balance the drum. They are bolted to the tank, and over time the fastenings can become loose. Also, counterweights sometimes crack (especially in cars Candy and Zanussi with plastic blocks).

Signs of a problem:

• 🔨 The car vibrates even at low speeds (400–600 rpm).
• 🔊 A dull thump is heard when the drum rotates.
• 🔧 If you shake the car manually, you can hear a knock inside.

How to fix:

1. Remove the top cover of the machine.
2. Locate the counterweights (usually located at the front and rear of the tank).
3. Check the fastenings: if the bolts are loose, tighten them with a 10 or 13 wrench (depending on the model).
4. If the counterweight is cracked, replace it (the cost of a new one is 800–2,000 rubles).

In some models (for example, Electrolux EW6F4R46SI) counterweights are secured with latches. If they break, the blocks can be glued with epoxy resin, but this is a temporary solution.

5. Faulty drum bearings

If the machine vibrates and buzzing When spinning, like a plane taking off, the bearings are most likely worn out. They are located at the rear of the tank and ensure smooth rotation of the drum. When they are destroyed, the following appears:

• 🔊 Loud noise (from buzzing to grinding).
• 🌀 The drum plays when you pull it towards you.
• 💨 Hot case in the rear wall area (due to friction).

Bearings fail due to:

• 💦 Water ingress (if the seal is damaged).
• ⏳ Natural wear and tear (service life - 5-10 years).
• 🔧 Incorrect installation during previous repairs.

Replacing bearings is a complex procedure that requires complete disassembly of the machine. The service center will charge 4,000–8,000 rubles for it (depending on the model). If you decide to do it yourself, prepare for what you will have to:

1. Remove the tank and disassemble it (in some models it is not dismountable, and you will have to buy a new one).
2. Press out the old bearings and install new ones (a puller will be required).
3. Replace the oil seal (required!).

In cars with direct drive (for example, LG Direct Drive) the bearings are integrated into the motor, and replacing them will cost more - up to 10,000 rubles.

6. Engine or tachometer failure

If the car vibrates unevenly (sometimes stronger, sometimes weaker) and at the same time “resets” the speed, the problem may be in:

• 🔄 Tachometer (speed sensor). It transmits incorrect data to the control board and the machine cannot stabilize the rotation.
• 🔌 Engine. Worn brushes or damaged windings lead to jerking and vibration.
• 📱 Electronics. A firmware failure or damage to the control board can cause chaotic changes in speed.

Diagnostics:

• Check if the error indicator is on (for example E03 in Indesit or UE in Samsung - indicates an imbalance or problem with the engine).
• Run test mode (for Bosch and Siemens - hold Start/Pause 3 seconds).
• Listen to the engine: if it howls or crackles, repairs are required.

Repair cost:

• Replacement of tachometer — 1,500–2,500 ₽.
• Engine repair (replacement of brushes) - 2,000–4,000 ₽.
• Replacement of the control board - 5,000–10,000 rubles.

⚠️ Attention: If the machine is under warranty, do not try to repair the electronics yourself! This will void the warranty. Contact the service center.

7. Foreign objects between the tank and the body

Sometimes vibration occurs due to foreign objects getting between the tank and the machine body: coins, buttons, bra underwires, or even socks. They block the movement of the drum, causing knocking and beating.

How to remove:

1. Unplug the machine.
2. Remove the top or back cover (depending on model).
3. Turn on a flashlight and look around the tank.
4. Carefully remove the items using tweezers or your hand.

In top-loading machines (Whirlpool, AEG) foreign objects often get stuck in the sealing rubber of the hatch. Check it all the way around!
