During the wash cycle of a washing machine, the water level increases primarily for two reasons:
Adequate water coverage: To ensure effective cleaning, the clothes inside the washing machine need to be fully submerged in water. By increasing the water level, the machine ensures that all garments are thoroughly soaked and that detergent and water can reach all areas of the clothes, maximizing the cleaning process.
Agitation and tumbling: Most washing machines use an agitator or drum that rotates back and forth to agitate and tumble the clothes. This movement helps to dislodge dirt and stains from the fabric. By having a higher water level, the clothes have enough space to move around freely during agitation, allowing for better cleaning action.
The process of water level adjustment typically involves sensors and a control system in the washing machine. When you start a wash cycle, the machine detects the weight of the clothes and calculates the appropriate water level needed to cover the load adequately. As the washing cycle progresses, the machine may continue to adjust the water level as necessary to maintain the desired water-to-clothes ratio for efficient cleaning.
Once the wash cycle is complete, the machine will drain the excess water and move on to the rinse and spin cycles, which do not require as much water as the wash cycle.
It's essential to use the appropriate water level for each load size to ensure optimal cleaning performance and water efficiency. Many modern washing machines offer various load size settings, allowing users to choose the appropriate water level for their specific laundry needs.
