How often should I clean the dishwasher filters?

The filter system is self-cleaning during normal use, but you should occasionally inspect it for foreign objects and clean when necessary. Remove the bottom rack to access the filters. The filter system consists of a Large Object Trap/Cylinder Filter assembly, a Fine Filter, and a Micro Filter. Use caution when reaching into the large object trap as it could contain sharp objects. Flush filters under running water to clean them.
