Abstract
A washing machine has a drum, a sump underneath the drum, a water circulation including an extractible drawer for introducing detergent or additives, the water circulation being in fluid connection to detecting means for detecting microfibers or contamination in the water and a circulation pump and pipes for circulating water. A method for its operation comprises the steps of branching off an amount of water circulating in the circulation and transporting it to the detecting means for being analyzed and analyzing the water in the detecting means. Depending on the result of this analysis, a filtering process with filtering means for filtering out the microfibers from the water is activated. The microfibers that have been filtered out can be collected and then removed easily from the washing machine.
