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

Remove the bottom rack, then grasp the Large Object Trap/Cylinder Filter Assembly and turn it counterclockwise one-quarter turn to lift it out. Flush the Cylinder Filter under running water, and also lift out and flush the Fine Filter and Micro Filter (on select models) under running water. Do not reach into the large object trap with your fingers as it may contain sharp objects. (Page 22)
