Cordless Vax vacuum displays “E6” or a filter icon with a fault symbol and suction is very weak.

Safety first: Switch OFF and remove the battery before removing the dirt bin or filters.

• 1. Empty the dirt bin: Remove the bin and empty it completely. Tap gently to dislodge compacted dust from the cyclone.
• 2. Clean the cyclone shroud: Use a soft brush to clean the mesh shroud inside the bin. Remove any fluff or hair wrapped around it.
• 3. Clean or replace the pre-motor filter:
  • Remove the pre-motor filter (often a foam or pleated cartridge).
  • Tap off loose dust. If washable, rinse under lukewarm water until clear. Squeeze gently (do not twist) and allow to air dry for at least 24 hours.
  • Do not refit a damp filter; this can damage the motor.
• 4. Check the post-motor/HEPA filter: If your model has a rear HEPA filter, remove and inspect it. Replace if grey, clogged, or damaged.
• 5. Reset and test: Reassemble all components, refit the battery, and test suction. The E6/filter warning should clear once airflow is restored.

Regular filter maintenance (every 1–3 months depending on use) prevents E6 faults and protects the motor.
