Cordless Vax vacuum displays “F2” and may emit a musty smell; exhaust airflow feels restricted.

Safety first: Remove the battery before accessing the rear or side filter covers.

• 1. Locate the HEPA/post-motor filter: Typically at the rear of the handheld body or under a side cover.
• 2. Inspect the filter: If it is dark grey, smells musty, or has visible dust matting the pleats, it should be replaced.
• 3. Replace the filter: Fit a genuine Vax replacement HEPA/post-motor filter of the correct type for your model.
• 4. Check airflow: After replacement, run the vacuum and confirm that exhaust airflow has improved and the F2 code clears.

Do not wash non-washable HEPA filters unless the manual explicitly states they are washable.
