The setting on a washing machine designated for “soil level” or sometimes “soiled load,” refers to the degree of dirtiness of the laundry. This setting adjusts the wash cycle’s duration and intensity. Selecting a higher level for heavily soiled items increases wash time and agitation, while a lower level is sufficient for lightly soiled items. For example, muddy work clothes would require a higher setting compared to lightly worn shirts.
Properly assessing laundry and selecting the appropriate setting is crucial for effective cleaning. Choosing a setting that matches the soil level optimizes water and energy usage, preventing both under-washing, which leaves clothes dirty, and over-washing, which can contribute to premature fabric wear. This feature, a relatively modern addition to washing machines, provides users with greater control over the washing process, contributing to better fabric care and resource efficiency.
