Vacuum powers on but immediately shuts off with E9; strong burning smell may be present

Safety first: Immediately turn OFF the vacuum, remove the battery pack, and do not continue to run the unit if you smell burning or see smoke.

Step-by-step checks:

• 1. Inspect for external obstructions: Confirm that the brush head and wand are free of jams and blockages. A heavily loaded motor can overheat and smell burnt.
• 2. Smell test at exhaust: With the battery removed, smell near the exhaust vent. A strong burnt electrical odor usually indicates internal motor damage.
• 3. Visual inspection: If accessible without full disassembly, look through vents for signs of melted plastic or soot.
• 4. Do not bypass protection: Do not attempt to repeatedly restart the vacuum to “clear” E9; this can cause further damage or fire risk.

When to stop: E9 with a burning smell almost always requires replacement of the main suction motor assembly or main body. This is a complex repair; contact a qualified technician or replace the unit if out of warranty.
