The rated laundry capacity in the instruction manual of the washing machine refers to the maximum weight of dry clothes that can be washed at one time on the premise of ensuring the normal operation of the machine and the washing effect.

If too many clothes are put in at a time, which exceeds the rated washing capacity of the washing machine, the load of the motor will increase when it works, and the temperature will rise rapidly, thus shortening the service life of the motor; Or because the motor is overloaded, the running speed will slow down, and the drive belt may even slip. In addition, there are too many clothes, which are intertwined and twisted together, and cannot be turned over in the washing bucket (under normal circumstances, the clothes roll 15 times per minute in the washing bucket), or even do not turn over at all. They just float on the water surface, and the friction between clothes, clothes and washing liquid or the bucket wall is weakened, and the force is uneven, which can not achieve the desired effect of kneading, rubbing, rinsing, and even washing.

On the surface, adding more clothes at a time will save time, washing powder and water, but in fact, the dirt on the clothes has not been washed away, or the cleanliness of the washed clothes is uneven, causing "waste". In serious cases, they still need to be washed again, which will cause waste of time and material, and increase the wear of clothes.
