Why does the Bosch washing machine rattle and knock during the spin cycle, what should I do?
Modern Bosch washing machines are equipment that meets all requirements for quiet operation. But in some cases, especially during the spin phase, the machine begins to make loud sounds.
This state of affairs almost always indicates a problem with Bosch and requires diagnostics.
We will explain further why a Bosch washing machine knocks during the spin cycle.

When is knocking normal?
If the sounds that a Bosch washing machine makes are different from what you are used to, you need to try to identify them. It happens that knocking from the drum is a normal situation.
Accessories on clothes
Clothing with metal buttons and rivets can make metal-on-metal noises.. When, during spinning or washing, accessories from clothes hit the glass of the hatch or the drum, a clanging sound is possible.
To prevent scratches on the surfaces of your Bosch washing machine, it is recommended to turn such items inside out before placing them in the drum.
Another method to solve the problem is to use laundry bags. This will eliminate the annoying “clicking” sound and protect the drum from scratches.
Fixing the hose
If the drain hose is not secured well enough, it may knock on nearby objects. and about the tank too.The solution to the problem is to remove the contact between the tank and the hose.
The problem with the hose knocking on the tank may in some cases not be felt when running an empty drum.
Incorrect installation of the Bosch washing machine
During the spin cycle, the Bosch washing machine works very intensively, as the drum rotates at high speeds. If the washing machine was installed incorrectly - unstable, too close to other furniture - then knocking may occur.
Causes of malfunction and solutions to the problem
If only things without metal fittings were placed in the Bosch drum, then knocking and other noise during the spin cycle should alert you. In this case there is a high probability that there is a problem with the equipment, which manifested itself during intensive rotation of the drum.
If it is necessary to open the case to diagnose the condition of the washing machine and individual components, you should disconnect the device from the electricity and turn off the water supply tap.
Foreign object
A knocking sound during the spin cycle, and sometimes during washing, very often indicates that a foreign object has entered the Bosch washing machine. It can be:
- keys,
- buttons,
- coins,
- underwires that have popped out of the bra, etc.
The washing machine should not be used in this condition. The work cycle must be stopped, and the foreign object must be removed. This is due to the fact that a foreign body can lead to serious damage, including damage to the tank itself. Repairs in this case will be very serious and expensive.
Sometimes a stuck foreign object can be removed without disassembling the washing machine. Bosch - through the drum.But more often it will be necessary to partially disassemble the washing machine and remove a foreign object through the seat of the heating element. At the same time, it would be a good idea to clean the drain filter - foreign objects may also remain in it.
Bearing wear
A problem with bearings is a situation typical for washing machines that have been in operation for a long time. Over time, the seal deteriorates and water begins to enter the bearings, leading to corrosion. As a result, the bearing assembly can no longer cope with the load, and its destruction begins.
Replacing bearings is a serious repair, which requires complete disassembly of the Bosch washing machine. It is advisable to carry it out in a workshop setting. Details - in this article.
Failure of shock absorbers
Over time, shock absorbers in a washing machine—parts that stabilize the position of the tank inside the washing machine body—become unusable. If they have lost functionality, the tank, when spinning, begins to oscillate over a wide amplitude and hit other components and even the body.
You can check the condition of the shock absorbers by simply pumping the tank Bosch washing machine. If they are worn out, the tank will begin to oscillate and only gradually stop. The solution to the problem is to replace the shock absorbers in the washing machine. This work is carried out with partial disassembly of the body.
Dampers are always replaced as a pair, regardless of the degree of wear of the second shock absorber. Details - in this article.
The solution to the problem of replacing shock absorbers is in the video:
Counterweight
Knocking and vibration during the spin cycle may be a sign of problems with the counterweight.. The balancing weight is installed on top of the drum and on the side of the front panel.
The main purpose of using a counterweight is to stabilize the position of the drum. If it is destroyed or the fastenings are loosened, a knock may occur when the washing machine is operating. This problem manifests itself especially clearly during the spin stage, when the drum movement is very intense.
Weakening the springs
In addition to dampers, the springs on which the tank is suspended are responsible for stabilizing the position of the tank inside the body of the Bosch washing machine. They have very high rigidity and usually serve without any complaints. But if for some reason they no longer fulfill their role, they need to be replaced with new ones.
The transport bolts are not unscrewed
Shipping bolts are used during the shipping process Bosch washing machine. They are screwed in from the rear wall to prevent free movement of the tank during transportation.
After the machine is installed in a permanent place, they need to be removed by inserting special plugs that come with the washing machine into the grooves.
If the transport links were not unscrewed before using the device, the Bosch washing machine may make a knocking noise both during the spin cycle and during washing. This is explained by the fact that the tank is forcibly held in a certain position, which does not allow it to move as technologically intended. Rigid fasteners do not allow springs and shock absorbers to soften vibrations.
If knocking occurs during the first wash in a new place, you need to check whether the transport bolts are unscrewed. Bosch usually has 4 of them.
The power filter is unscrewed from the fastener
The interference filter is used to suppress interference generated by household appliances. If the fasteners are loose and the device is unscrewed, it may hang inside the case on the wires and hit the drum, making a knocking sound when spinning.
Re-securely securing the surge protector will help solve the problem.. You can clarify that the problem is in this particular part after opening the case and gaining access to the unit.
Drum overload
Too much stuff in the Bosch drum can form a heavy lump, which will hit the walls with a thud when spun. This use of equipment is extremely undesirable, as it creates an increased load on components, including dampers, bearings, axles, etc. The solution to the problem is to interrupt the cycle and put the laundry in the drum. It's better to take some things out.
Motor mount
Knocking sound when spinning Even a motor can make noise - if it is poorly secured in its mounting socket. When entering the spin cycle, the Bosch motor works very intensively, forcing the drum to rotate using a belt.
If the fastenings are loose, the motor is not securely fastened. It can hit the metal and transmit uneven movement to the drive belt. The solution to the problem is to open the washing machine body and secure the motor.
Preventive measures
To avoid the problem of knocking when spinning a Bosch washing machine, The following preventive measures should be taken into account:
When putting things into the drum, you should avoid getting foreign objects into it - keys, coins, etc. To do this, it is important to check all pockets and strengthen all fittings in advance.- Overloading the drum, especially in cases where it occurs frequently, can accelerate the wear of washing machine elements, including bearings and shock absorbers.
- The installation of the washing machine must be carried out in accordance with all the rules.
- The transport bolts must be unscrewed immediately after transporting the washing machine to a new location.
Conclusion
If your Bosch washing machine begins to make a knocking sound that is uncharacteristic of normal operation during the spin cycle, the problem must be solved immediately. This requires high-quality diagnostics and, possibly, repairs with replacement of parts. A knocking sound during the spin cycle accompanies various breakdowns, which, if not eliminated in time, will lead to very complex and financially costly repairs.
