Carpet cleaner shuts off by itself after a few minutes of use and restarts after cooling

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

• Clean all filters: Remove pre-motor and post-motor filters. Wash or replace as specified in the manual.
• Clear vents: Use a soft brush or vacuum to clean all air intake and exhaust vents.
• Reduce load: Use slower passes and avoid pressing down hard on the handle, especially on thick or high-pile carpets.
• Monitor operation: If the unit continues to shut off quickly after cleaning and reducing load, the motor or thermal protector may be failing and require replacement.
