Display shows E06 and the vacuum will not start or stops shortly after starting, often accompanied by a burning smell.

Safety: Immediately stop using the vacuum if you smell burning or see smoke. Remove the battery and do not attempt to power it on again until inspected.

• 1. Visual inspection: Remove the dust bin and access the motor housing. Look for discoloration, melted plastic, or soot around the motor and wiring.
• 2. Check wiring harness: With the battery removed, gently tug on the motor connectors to ensure they are secure. Look for burnt or brittle insulation.
• 3. Smell test: If the motor area smells strongly of burnt electronics, the motor windings or driver circuit are likely damaged.
• 4. Do not bypass protection: Do not attempt to bypass fuses or thermal cutouts. These are safety devices preventing fire.
• 5. Replace faulty components: If you confirm visible damage to the motor or PCB, replace the entire motor assembly or main control PCB as appropriate. These parts are not user-repairable at component level.

Because this fault involves high current and potential fire risk, professional service is strongly recommended if you are not experienced with electrical repairs.
