E6 error, Hoover carpet cleaner indicates overheating and shuts off during use

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

• Clean filters and screens: Remove the lint screen, intake filter, and any foam filters in the air path. Rinse with warm water and allow to dry completely before reinstalling.
• Check airflow path: Inspect the nozzle, hose, and suction channels for clogs. Remove any debris, pet hair, or carpet fibers.
• Ventilation: Ensure the motor vents on the sides or rear of the unit are not blocked by furniture, walls, or dust buildup. Clean with a soft brush.
• Test after cooling: Once fully cooled and cleaned, plug in and test. If the unit overheats quickly again, the motor or thermal sensor may be failing and should be serviced.

Persistent E6 errors usually indicate a failing motor or thermostat and may require professional replacement.
