Where is the drain pump filter located on a Toshiba washing machine, and how do I clean it if the E9 error code appears?

The drain pump filter is usually located at the bottom front of the machine, behind a small access panel. To clean it, open the panel, place a shallow container to catch water, unscrew the filter (usually by turning it counterclockwise), and remove any lint, debris, or foreign objects. Reinstall the filter securely after cleaning.
