When a washing machine specifies a weight capacity of 7kg, it typically refers to the maximum weight of dry clothes that the machine can effectively wash. This means that you should not exceed the 7kg limit with dry clothes.
It's important to note that the weight capacity mentioned on washing machines does not account for the weight of water or wet clothes. When you load wet clothes into the machine, they will absorb water during the washing process, and their weight will increase. The machine's capacity rating is based on the assumption that the clothes will absorb water, so you can generally load 7kg of wet clothes without exceeding the machine's capacity.
To ensure efficient and effective washing, it's recommended to follow the manufacturer's guidelines and not overload the machine. Overloading can lead to inadequate cleaning, excessive wear on the machine, and potentially even damage to the washer.
