Why is the drum knocking in the washing machine

knocking machine drumThe unpleasant sounds made by the washing machine do not just happen. This "musical" accompaniment of washing has a certain reason. A knock in the drum appears in various cases, and above all, when one of the nodes of the machine “lost” its place.

As a result, he hits the drum and knocks. What to do, how to find a breakdown and fix it?

Possible reasons

People differently describe the sound of a drum. Indeed, in some cases this can be called a knock, while in others, sounds are like a rattle or rumble. We list the possible reasons why the drum knocks:

  • There is a foreign object between the drum and the tank. In this case, the drum knocks both during washing and during spinning;
  • an imbalance of linen can also cause a knock, such a knock most often occurs during the spin cycle;
  • improper installation of the washing machine, relative to the floor level, can also lead to a knock on the drum. The problem is solved quite simply, they put the level on the machine and begin to adjust the legs until the washing machine is level;

  • bearing failure - this is one of the most serious and frequently occurring problems, regardless of the brand and model of washing machines. Bearings wear out over time, and therefore need replacement;
  • malfunction of shock absorbers leads to the fact that the tank and drum warp and begin to knock;
  • deformation or weakening of the counterweight can also lead to the appearance of an extraneous knock. Such a problem is extremely rare and is solved by tightening the bolt on the counterweight. And in case of a part breakdown - by replacement;

  • a surge protector torn from the housing can also cause knocking.

Unbalance underwear

The uneven distribution of things most often occurs when there are too few things in the car, or these are too small things or vice versa large ones.

Note! In modern washing machines, the problem of imbalance does not arise, since they have a control system, such a breakdown is characteristic of old-generation washers.

To eliminate the cause, you need to open the drum of the machine, and spread the laundry on the drum with your hands. If necessary, first drain the water through a drain filter or emergency drain hose, otherwise the hatch door will not open. You can also avoid imbalance if you mix large and small things in the drum of the washing machine, of course, given the type of fabric and color.

We remove a foreign object

If a foreign object enters between the drum and the tank, the washing machine must not be operated. To understand that something got into the drum is pretty simple. You need to spin the drum from side to side with your hand when the machine is turned off and without laundry. Such metal objects as coins, a bone from a bra, pins, metal buttons, rivets will ring, this sound you will not confuse with anything. In addition to metal objects, debris can be stuck in the tank, for example, seeds not shaken from the pocket.

Be careful when putting things in the drum, check pockets and whether small parts are sewn securely on clothing. Do not forget to check the drum itself, as well as the powder applicator, small children can put a foreign object there.

Removing a foreign object is not so easy. In some cases, it is impossible to get an item without removing the tank from the machine and without taking it apart. Moreover, tanks are non-separable, which complicates everything. Different methods of extracting objects, for example bones from a braare described in an article on our website.

Checking and replacing bearings

bearing wearThe knock of bearings, as a rule, is preceded by a creak. Therefore, you need to listen to how the washing machine works. If bearing wear is suspected, do not operate the machine. The part may break so that the machine will not be repairable.

You can determine the failure of the bearings by twisting the drum with your hand from side to side and shaking it up and down. If you find backlash and hear a knock, then definitely the bearings need to be changed. Bearing life is approximately 5 years, so repairs may be inevitable. Replacement refers to a difficult repair, so for help most often turn to a specialist. But if you want to repair the equipment yourself, then read the article How to change bearings in a washing machine.

Shock absorbers and FPS

If the washing machine knocks and vibrates at the same time, the cause may be defective shock absorbers. Thanks to the shock absorbers, the vibration that occurs at high speeds is damped, and if they are worn out over time, the tank with the drum will swing like a pendulum, extraneous noise will appear.

Repair of shock absorbers in most cases is impractical, it is better to replace them.

In addition, it is not so difficult to do this in almost all washing machines, the exception is Samsung and Hans brand equipment. To replace the part in these machines, you will have to pull the tank out of the case, in all other cases, the replacement is made without removing the tank, the detailed instructions of which are presented in the video below.

If the surge protector became the cause of the drum knock, then in this case it must be securely fixed to the machine body. It is located behind the rear wall of the housing. To remove and fix it, it is necessary to remove the top cover, find the torn filter and fix it to the side wall on the holders using self-tapping screws.

Thus, to understand why an automatic washing machine knocks, you need to listen to it well and spin the drum with your hand. Even if it is not possible to name the one hundred percent cause of the breakdown, then at least to limit their range is definitely possible. And only after that seek the help of a specialist.
