Vacuum runs for only a few seconds and then stops with an E8 or eight-blink pattern; body feels hot to the touch.

Safety first: Remove the battery immediately if the vacuum feels excessively hot. Allow all components to cool before further inspection.

Steps to try:

• Cool-down period: Let the vacuum sit powered off with the battery removed for at least 45–60 minutes.
• Clear airflow path: Disassemble the dust cup, cyclone, wand, and nozzle. Remove any clogs and clean filters thoroughly.
• Inspect motor vents: Look at the motor housing vents for lint buildup. Use compressed air or a soft brush to clear them.
• Check for abnormal noise: After cooling and cleaning, run the vacuum briefly. If the motor sounds rough, squeals, or smells burnt, the motor windings or bearings may be damaged.
• Repeated trips: If the thermal cutoff activates again quickly under light use, the motor or thermal sensor is likely failing and the motor assembly should be replaced.
