Vacuum shows E8 and shuts off immediately when trigger or power button is pressed

Safety first: Use only the original Levoit charger and battery pack. Do not attempt to open the battery pack.

• Charge fully: Place the vacuum or battery on the charger and allow it to charge uninterrupted for at least 3–4 hours, or until the indicator shows full.
• Check charging indicators: Confirm that charging lights on the vacuum or dock behave normally (blinking then solid). If no lights appear, the charger or battery may be faulty.
• Warm to room temperature: If the vacuum or battery was stored in a very cold environment, bring it indoors and let it reach room temperature for 1–2 hours, then attempt charging again.
• Test runtime: After a full charge, run the vacuum on low power. If it shuts off quickly and shows E8 again, the battery cells are likely degraded.
• Replace battery: If E8 persists after proper charging, replace the Levoit battery pack with a genuine unit. Do not use third‑party packs that may not communicate correctly with the BMS.
