What does the knocking of the washing machine tell you?
The washing machine knocks - it indicates the presence of some malfunction.
Let's try to understand the nature and causes of the breakdown.
Let's list the causes:
- Frayed or unevenly distributed laundry during washing or spinning. If the washing machine knocks for this reason. it does not mean it is broken. Solution: turn on the drain, and after it is finished, turn off the machine and wait for the door to unlock. Then take out and shake the laundry. You can then load the items back into the machine and rinse.
- The counterweight is broken or the bolts fixing it are loose.
- The shock absorbers broke, the spring broke.
We have already told you how to solve the problem with rewinding the laundry. Now let's move on to more serious reasons why The washing machine can rattle, knock or make a grinding noise.
Failed shock absorbers or burst spring
First of all, according to basic safety requirements, de-energize the washing machine and shut off the water just in case.
The tank of a washing machine is a moving element, shock absorbers and springs provide it with a semi-spring fixation, they also serve to reduce vibration and prevent the tank from touching other surfaces of the machine. As you can see, the main purpose of shock absorbers and springs is to prevent breakage due to mechanical impact.
A heavy load on shock absorbers and springs during operation can cause damage or breakage. As a consequence, the tank is skewed, which hits the inner walls of the washing machine during operation. The appearance of a loud metallic knock is a signal to immediately stop the machine. Determining the exact cause of the malfunction and its elimination is better entrust the identification of the exact cause of the malfunction better to the master.
If the washing machine is banging due to the fact that the spring is broken, then this part needs to be replaced. To do this, you will need to remove the top cover of the washing machine, disconnect the spring, remove the counterweight and only then replace the faulty spring.
Replacement of the failed shock absorber is also better to entrust to a master.
Defective counterweight
A counterweight is a weighting device fixed to the bottom of the case. Its main function is to dampen the vibration that occurs during the operation of the equipment. Loosening of the bolts that fix the counterweight can cause the washing machine to rattle, which in this case will occur in the cycle of spinning the laundry. Master will help you tighten the bolts or replace the counterweight when necessary.
As you can see, it is easy enough to understand the cause of the knocking that occurs during the operation of the washing machine, but the repair most often can cope only a specialist.
