How do I clean the filter system in my Bosch dishwasher?

Remove the bottom rack, then grasp the Large Object Trap assembly and turn it counterclockwise to lift it out. Tap it gently on a flat surface to dislodge debris, and flush the Micro Filter under running water. To reinstall, return the fine filter to position and turn the locking nut clockwise until locked, ensuring the arrows on the ring handle and fine filter point toward each other. (Page 14)
