Unit shuts down shortly after starting; E8 displayed; may feel hot to the touch around motor area.

Safety first: Unplug the unit and allow it to cool for at least 30 minutes.

• Clean filters: Remove and clean all accessible filters (pre-motor, post-motor, lint screens). Rinse washable filters with lukewarm water and allow to dry completely before reinstalling.
• Clear airflow path: Check the hose, wand, and nozzle for clogs. Use a flexible brush or straightened coat hanger (carefully) to push out blockages.
• Inspect cooling vents: Look for dust buildup on the motor housing vents. Vacuum or brush away debris to restore airflow.
• Check motor fan: If accessible, verify that the motor cooling fan is intact and spins freely. A broken fan will cause rapid overheating and requires motor replacement.
• Temperature sensor: Some models use a thermistor near the motor. Inspect its wiring and mounting. A loose or damaged sensor can falsely trigger E8 and should be replaced.
