The vacuum shows E07; suction is very weak or absent even though the motor sounds like it is running.

Safety first: Turn off the vacuum and remove the battery before removing the dust bin.

• 1. Remove and reinstall the dust bin: Detach the dust bin completely and then reinstall it, ensuring it clicks firmly into place. Misalignment can trigger an error and cause loss of suction.
• 2. Inspect seals and gaskets: Check the rubber seals around the cyclone and bin connection points. Look for tears, deformation, or missing seals. Replace the dust bin or seal kit if damaged.
• 3. Clean cyclone ports: Open the bin and gently tap the cyclone assembly to dislodge fine dust. Use a soft brush to clean the small cyclone holes. Do not use sharp objects that can deform the plastic.
• 4. Check for cracks: Inspect the dust bin for hairline cracks, especially around the latch and connection to the main body. Cracks can cause air leaks and trigger E07.
• 5. If E07 remains after reseating and cleaning, the bin presence sensor or pressure sensor may be faulty and require professional service.
