Vacuum runs but suction is very weak; display shows E13 or filter icon; unit may pulse on and off.

Safety first: Turn the vacuum OFF and remove the battery pack before disassembling the dust system.

• Empty and clean dust bin: Remove and empty the dust container. Detach the cyclone assembly and use a soft brush to clean all holes and mesh surfaces.
• Clean or replace pre-motor filter: Remove the pre-motor filter. Tap it gently to remove dust. If washable, rinse with lukewarm water until clear, then air-dry completely (24 hours) before reinstalling. Replace if damaged or permanently discolored.
• Service HEPA filter: Remove the HEPA exhaust filter. Tap gently to remove loose dust. Replace if suction remains weak or if the filter is older than the manufacturer’s recommended interval.
• Check wand and attachments: Look through the wand and any flexible hose for blockages. Use a long rod or broom handle carefully to push out clogs.
• Reassemble and test: Once all components are clean and dry, reassemble and test. If E13 persists with clear airflow, the pressure sensor or control PCB may be faulty.
