The KitchenAid KDTM354DSS dishwasher does not have a self-cleaning filter. Instead, it features a manual filter system designed to trap and remove food particles and debris from the dishwasher's water, thus preventing them from redepositing the dishes during the cleaning cycle. The manual filter in the KitchenAid KDTM354DSS dishwasher is located at the bottom of the dishwasher tub, beneath the lower rack. It is essential to periodically clean and maintain this filter to ensure optimal dishwasher performance and cleaning results. Depending on the frequency of use and the amount of food debris, it is recommended to clean the filter about once a month or as needed. To clean the manual filter, follow these general steps: 1. Remove the lower rack to access the filter assembly. 2. Lift out the cylindrical filter assembly, which usually includes the mesh and fine filters. 3. Rinse the filter under warm running water to remove food particles and debris. 4. Check for any clogs or blockages and clear them if necessary. 5. Reassemble the filter components and place them back into the dishwasher. 6. Reinstall the lower rack. Regularly cleaning the manual filter will help maintain the dishwasher's performance, prevent clogs, and ensure your dishes come out clean after each cycle. Please keep in mind that appliance models and specifications can change over time. For the most up-to-date information about the KitchenAid KDTM354DSS dishwasher or any other product, it is recommended to refer to the product manual or contact the manufacturer directly.
