LED display shows a filter icon even after filter has been cleaned

Safety: Remove the battery before handling filters.

• Re-clean and dry filter: Ensure the pre-motor filter is completely dry and free of detergent residue.
• Check seating: Reinstall the filter firmly in the correct orientation so that any sensor tabs or magnets align properly.
• Reset maintenance indicator: Follow the user manual procedure (often holding a specific button for several seconds) to reset the filter indicator.
• If the icon remains: The filter sensor or PCB may be faulty. Continued use is possible but filtration performance should be monitored. Service is recommended for sensor replacement.
