Cordless vacuum shows E5 and shuts down after a short run time, body feels unusually warm.

Safety first: Remove the battery and allow the vacuum to cool for at least 30 minutes before further inspection.

• Step 1 – Allow cooling: Let the unit rest in a cool, dry place away from direct sunlight until it is at room temperature.
• Step 2 – Clean filters thoroughly: Remove all filters (pre‑motor sponge, mesh, and HEPA). Wash washable filters under lukewarm water until clear. Squeeze out excess water gently and air‑dry for 24 hours. Do not use heat sources to speed drying.
• Step 3 – Check vents: Inspect the air vents around the motor housing on the Tower main body. Use a soft brush to remove dust buildup that can restrict cooling airflow.
• Step 4 – Inspect cyclone: Clean the cyclone shroud and internal cones to ensure free airflow.
• Step 5 – Usage pattern: Avoid running on turbo mode continuously for long periods, especially on thick carpets. Alternate between power levels.
• Step 6 – Replace motor assembly: If E5 recurs quickly even with clean filters and vents, the motor’s thermal sensor or cooling fan may be defective. Replace the Tower main motor assembly as a complete module.
