The soil level on a washing machine refers to the amount of dirt or soil on clothes, and it is a setting that can be adjusted to help determine the appropriate wash time and amount of detergent needed for each load. Soil level settings can vary among washing machine models and brands, but they typically include options such as "Light," "Normal," and "Heavy". The Normal soil level setting is programmed to handle everyday garments with normal amounts of soil and is the most commonly used soil level. The soil level selection may change wash time, detergent dosage (bulk dispenser models only), wash motion, water temperature, and/or water level to alter wash performance, depending on the model of the washing machine. It is important to choose the right soil level to ensure a more exact time for washing, save water and energy based on the soil level of clothing, and get optimal cleaning results. The soil level of laundry can be easily determined by the visibility of stains, and clothing that has been lightly worn can be thoroughly washed using the Light soil setting, while items with visible food stains and noticeable scents may require a higher soil level setting.
