Why does the washing machine knock when washing or squeezing and what to do when knocking

Yesterday the car worked without complaints, but today a loud knock comes from it? Do not be in a hurry to get upset and call the repair shop. Perhaps, everything is not so serious.

To begin with, listen: are not the alarm sounds caused by large plastic buttons, metal buttons and other stiff details of clothing that hit the drum while rotating. If the reason is found, next time before loading the laundry, turn it inside out or put it in a special pouch.

The contents of the drum with nothing to do with it? Then without delay, proceed to find the causes of the problem.

Before starting the inspection, unplug the appliance and shut off the water supply. When examining the equipment in search of the cause of the fault, note the following:

The uneven distribution of the contents is typical for outdated models of washing equipment. Linen in such devices falls in a com. This causes an imbalance - and the drum strikes against the body of the machine at every turn. To solve the problem, interrupt the operation of the equipment and align the contents of the drum manually. In new models, such a drawback is eliminated.

Make sure that the machine is installed correctly, will help the building level, which is placed on the housing cover. Another way to verify - an attempt to swing the machine: if the installation is carried out according to the rules, the design does not stir.

In cases where an uneven surface is detected under the machine, adjust the balance using silicone supports, which are now sold in any specialized store.

In modern washing machines, the system for eliminating imbalance is based on the operation of springs and shock absorbers to which the tank is attached. With their help vibration is compensated and equilibrium is regulated. Over the years, these parts lose elasticity, wear out and, as a result, are damaged. Often, their failure is the cause of the knock.

The manifestation of such a malfunction will be a displacement or an unusual inclination of the tank, as a result of which it will strike other internal parts of the device at startup. In this case, immediately interrupt the washing process and repair the breakdown by disassembling the unit and replacing the faulty parts. Along the way, check the condition of the shock absorber mountings and tighten them if necessary.

Shock absorbers stretched so hard that they touch the bottom wall of the tank, giving rise to a knocking? They also require immediate replacement. Even if the condition of one of them does not cause censures, it is necessary to change both at once. Otherwise, the load will be distributed unevenly.

How to independently replace shock absorbers, see the following video tutorial.

To ensure that the soaked and heavy laundry does not disturb the balance of the equipment during washing, a counterweight is attached to the bottom or top of the tank - a concrete weight that makes this part heavier and the machine stable.

If the device vibrates and vibrates during spin, evaluate the counterweight condition. Over time, the anchorages on which the load is held weaken, and it starts to dangle, banging against the tank with a knock. To eliminate this problem, the machine must be disassembled and tightened with the fixing bolts. Sometimes it is found that the counterweight is damaged, then it must be replaced. Difficulties with the purchase of replacement parts will not arise. Attach a new load to the tank, assemble the machine - and proceed with the washing.

A drum knock is usually caused by three reasons:

• A small object has hit the tank, which, when rotating, beats against the drum. The danger of this problem is that the drum can jam. It is necessary to interrupt the operation process and remove any excess from the tank. To do this, remove the front or back wall of the case( which one depends on the model of your washing equipment);Remove the heater and remove the debris through the opening.
• If the scratch is preceded by a scratch, the cause of the fault lies in the wear of the bearing. This part of the structure needs to be replaced. Typically, such problems are associated with a long service life of the equipment. Professional repairmen warn that the elimination of such a malfunction involves the replacement of all bearings and seals, since the failure of one element indicates the deterioration of the system as a whole.
• A network filter attached to the rear wall of the cabinet( its main function - protecting the machine from power surges) can become a cause of the knock. During operation, the screws on which it is held weaken, and the filter begins to touch other parts of the device. In this case, the part must be securely fixed, replacing the loose fixtures, if necessary.

Remember that when there is a knock or other foreign sounds, the machine must be stopped because loose and faulty parts can cause serious damage to the operating mechanism.
