Detergent compartments and proper detergent use in German washing machines

German washing machines typically have three compartments in the detergent drawer. The left compartment (marked II) is for the main washing powder or liquid detergent. The middle, smaller compartment (marked III) holds fabric softener, which is released later in the cycle. The right‑hand compartment is used only when a pre‑wash program is selected; it receives detergent for the pre‑wash stage, which is advisable for heavily soiled items such as sport clothing, stained workwear, or wool.

Using the correct compartment and dosing detergent appropriately can lower washing costs, reduce water and energy consumption, and lessen environmental impact. Over‑dosing is common when users add detergent by feel rather than by the recommended amount, leading to higher expenses and potential residue on fabrics. Selecting lower wash temperatures (e.g., 30 °C instead of 40 °C) can cut electricity use by over 35 % according to the German Environment Agency. Proper use of the compartments therefore saves money and resources while maintaining cleaning performance.
