The situation when washing machine begins to make loud, frightening sounds during the spin cycle, familiar to many owners of household appliances. Instead of the usual monotonous hum of the engine and the splash of water, you hear a clang, rumble or rhythmic knocking, which makes you think about urgently calling a repairman or buying a new unit. This noise is not just irritating to the ear, it signals that a malfunction has occurred within the mechanism, which, if ignored, can lead to serious damage and flooding of neighbors.
Before you panic, it is necessary to conduct an initial diagnosis to localize the source of the problem. Often the reason is trivial roar become objects that accidentally fall into the drum, or a banal overload of laundry that the automation cannot cope with. However, if you are confident in the correct operation, the problem may lie in the wear of critical components, such as the bearing assembly or shock absorbers.
In this article, we will analyze in detail all the possible reasons why your equipment is noisy, and provide a step-by-step action plan for troubleshooting. We will look at both simple cases that can be solved in five minutes, and complex technical problems that require disassembling the case and replacing parts. Understanding the nature of sound is the first step to successful and cost-effective repairs.
⚠️ Attention: If you hear not just a loud hum, but a characteristic metal grinding or crackling sound, stop using the device immediately. Continued operation in this mode may lead to tank destruction and engine seizure.
Foreign objects and unbalanced laundry
The most common and easily eliminated reason that washing machine rattles, is the presence of foreign bodies between the tank and the drum. Coins, buttons, bra wires, or small items forgotten in pockets can get stuck in the space where the drum rotates. When the speed is high, these objects begin to hit the walls, creating the effect of a hammer drill. Also, a situation often occurs when the laundry bunches up into one dense lump on one side of the drum, causing severe imbalance.
Modern models are equipped with an imbalance control system, which should automatically redistribute the laundry or reduce the rotation speed. However, if things are too heavy or their quantity is minimal, the system may not be able to cope, and the machine will begin to “jump” and rattle. In this case, you need to stop the wash, manually straighten the laundry and start the spin cycle again. To check for the presence of foreign objects, sometimes it is enough to gently shake the empty drum with your hand, listening to the sound.
To avoid similar situations in the future, always check pockets before loading and use special bags for washing delicate items with accessories. Regular cleaning of the drain pump filter also helps identify small objects that have already entered the system, but have not yet reached the narrow gap between the tank and the drum.
Bearing wear
If your washing machine makes a noise reminiscent of an airplane taking off, which intensifies as the drum speed increases, there is a high probability that the problem lies in bearings. This is the core of the rotation mechanism, and their destruction is one of the most serious failures. At first you may hear a slight noise, but over time it develops into a deafening roar and clanging, especially noticeable in the spin mode.
You can diagnose bearing wear by opening the hatch and sharply turning the drum by hand. If you hear a characteristic rustling, hum or feel unevenness, it means that the lubricant has dried out and the metal elements have begun to rub against each other. Ignoring this symptom will lead to the seal losing its seal, water getting into the engine, and repairs will cost a complete replacement of the tank or the entire unit.
Replacing bearings is a labor-intensive process that requires complete disassembly of the machine and, often, sawing of the tank (if it is not dismountable). In some cases, it is more economically feasible to replace the entire tank and drum assembly, since the cost of labor and new parts can be a significant part of the price of new equipment.
⚠️ Attention: Operating a machine with damaged bearings is strictly prohibited. A flying bearing can pierce the tank, leading to instant flooding of the room and failure of the electronics.
How to extend the life of bearings?
Use only high-quality powders, do not overload the drum and be sure to wipe the hatch seal after each wash so that the water does not stagnate and destroy the seal.
Problems with counterweights and shock absorbers
The design of any washing machine includes weights (counterweights) and damping elements (shock absorbers) that dampen vibration. If the machine begins to rattle and “jump” around the bathroom, inspect the fastenings counterweights. These are solid concrete or cast iron blocks that can crack or loosen over time. A cracked counterweight produces a dull but very loud knocking sound every time the drum rotates.
Shock absorbers and springs also play a key role. The springs on which the tank is suspended may stretch or burst, and shock absorbers may lose their properties due to leaked fluid or wear. Check their condition by shaking the tank by hand (after unplugging the machine). If the tank moves too freely, like jelly, or, conversely, is tightly jammed, the problem is in the damper system. Replacing these elements usually does not require complex tools and can be done independently.
Therefore, if any loosening of the bolts is detected, they must be immediately tightened using a thread locker to prevent repeated loosening due to vibration.

Malfunctions of the drain pump and heater
Sometimes the source of noise does not lie in the rotating parts of the drum, but in peripheral systems. If the drain pump (pump) becomes clogged or gets hit by a solid object, it may hum and rattle while trying to pump water. This is especially noticeable in pauses between spins, when water is pumped out. Likewise, heating element (heating element) covered with a thick layer of scale may make a crackling noise when heated, which resonates with the body of the machine.
If a bone or coin gets into the pump, the impeller begins to hit the pump body. In this case, cleaning the filter helps, but if the object has gone deeper, the pump itself will need to be removed and disassembled. Scale on the heating element not only reduces heating efficiency, but also creates a risk of the coil burning out, so regular use of anti-scale agents or installing magnetic filters on the water supply hose is a necessary preventive measure.
You can diagnose the pump by starting the “Drain” or “Spin” mode and listening to the bottom of the machine. If the sound comes from there and is accompanied by difficulty draining water, the problem is in the pump. Replacing this unit, as a rule, does not take much time and is relatively inexpensive.
To prevent heating element noise, use special water softener magnets that are attached to the inlet hose, or add citric acid to an empty drum every 3-4 months.
Loose fasteners and pulley
Constant strong vibration is the enemy of any threaded connections. Over time, the bolts holding various components of the washing machine may spontaneously unscrew. Particular attention should be paid to the nut securing pulley to the drum shaft. If it is weakened, the pulley begins to dangle and emit a rhythmic metallic clang, the frequency of which depends on the speed of rotation.
Also check the mounting bolts for the engine, pump and the counterweights themselves. Often it is enough to simply tighten up the available connections to eliminate extraneous sound. However, if the threads are torn or the bolts are stretched, they must be replaced with new ones of the appropriate strength class. Using conventional bolts instead of original ones can lead to their rapid destruction due to vibration.
To perform this diagnostic, you will need to remove the rear cover of the machine (on top-loading models, the side panels). A visual inspection often allows you to immediately notice a bolt that is hanging on the “snot” or has completely fallen out of its socket. Regular maintenance and tightening of fasteners can significantly extend the life of your equipment.
⚠️ Attention: Before any work inside the cabinet, be sure to disconnect the washing machine from the power supply! A rotating pulley and live contacts pose a fatal hazard.

Frequently asked questions (FAQ)
Is it possible to continue washing if the machine is humming a little?
If the hum is barely noticeable and does not increase, it may be a feature of the model or a small object. However, the growing noise cannot be ignored. Critical sign is the appearance of play in the drum (if you pull the top edge, it should not move up and down relative to the tank). If there is play, it is prohibited to continue washing.
Why does my new washing machine rattle when spinning?
New equipment may make noise due to transportation bolts that were forgotten to be removed before installation. They secure the tank for transportation and during operation create strong vibration and noise. An uneven floor may also be the cause - be sure to adjust the feet to the level.
How much does it cost to replace bearings at a service center?
The cost consists of the price of parts and the complexity of the work. If the tank is non-separable, it needs to be sawed, bearings replaced and hermetically assembled, or a new assembled tank must be purchased. On average, repairs cost 40-60% of the cost of a new car, which often makes buying new equipment a more rational decision.
How to check shock absorbers without disassembling the car?
Open the hatch, press firmly on the drum from top to bottom and release. If the tank rocks 1-2 times and immediately stops, the shock absorbers are working properly. If it continues to swing like a pendulum, the dampers are worn out and require replacement.
