The unit shuts down shortly after starting, E09 is displayed, and a strong burning smell may be present.

Safety: Immediately unplug the cleaner if you smell burning or see smoke. Do not attempt to restart.

• Inspect for water leaks: Check around the motor housing for signs of water. If the dirty water tank or seals have leaked, dry the area thoroughly and identify the source of the leak.
• Check suppression capacitor: Locate the motor suppression capacitor (often near the motor terminals). Look for bulging, cracking, or leakage. Replace if defective.
• Test motor windings: With a multimeter, measure resistance across the motor terminals. A very low resistance (near short) or visible burn marks indicate a failed motor.
• Inspect wiring: Examine the motor wiring harness for melted insulation or exposed copper. Repair or replace the harness as needed.

Because this fault involves a potential fire risk, replacement of the complete motor assembly by a professional is strongly recommended.
