Filtration System Your dishwasher has the latest technology in dishwasher filtration. This filtration system minimizes sound and optimizes water and energy conservation while providing superior cleaning. The filter system consists of two parts, an upper filter assembly and a lower filter. IMPORTANT: To avoid damage to dishwasher, do not operate your dishwasher without filters properly installed. Be sure lower filter is securely in place and upper filter assembly is locked into place. If upper assembly turns freely, it is not locked into place. The filters may need to be cleaned when: Upper filter assembly ■■ Visible objects or soils are on the upper filter assembly. ■■ Dishes feel gritty to the touch.
