  If the automatic filter cleaning on your Kärcher Vacuum Cleaner isn't working, ensure the filter cover is properly closed and locked. Check the suction system for leaks and repair them. Also, verify the correct positioning of the flat fold filter. Inspect for leaks between the suction head and the waste container, and make sure the suction hose is connected. If using a suction hose diameter greater than DN 35 on a Te model, ensure the speed regulator is correctly adjusted or set the suction performance to max. Finally, check or replace the Tact filter cleaning system ON/OFF switch or the PCB.
