Possible Causes
Brush roll jammed causing belt or motor to overheat, Severely clogged filters restricting airflow, Failing main motor windings, Debris caught in motor vents
How to Fix / Troubleshooting
Safety first: Immediately switch off the vacuum, remove the battery pack, and allow the unit to cool. Do not continue using it until the cause is found.
- 1. Inspect brush head: Remove the floor nozzle and check the brush roll for jams. Clear all hair and debris.
- 2. Clean filters and bin: Empty the dust bin and clean/wash filters as specified for your Grundig model. Blocked filters can cause the motor to overheat.
- 3. Check for visible damage: Smell near the motor vents. If there is a strong electrical burning odor or visible discoloration, the motor may be failing.
- 4. Test briefly: After cooling and cleaning, reinstall the battery and run the vacuum for a short period while monitoring for smell. If the burning smell returns quickly, stop use and have the motor or nozzle assembly inspected and replaced by a technician.
