Possible Causes
Blocked air path causing motor overload, Shorted brushless motor windings, Faulty motor driver circuit on main PCB, Jammed brushroll causing high current draw
How to Fix / Troubleshooting
Safety: Remove the battery pack before inspecting the nozzle or motor area.
- Check for blockages: Remove the floor nozzle, wand, and dust bin. Inspect the inlet, cyclone, wand, and nozzle neck for clogs (hair, dust bunnies, plastic). Clear all debris.
- Inspect brushroll: Remove the brushroll from the motorized nozzle. Cut away hair and threads from bearings and bristles. Ensure the brushroll spins freely by hand.
- Test without nozzle: Reinstall the battery and run the vacuum with only the main body (no wand/nozzle). If it runs normally, the fault is in the nozzle motor or brushroll.
- Check filter condition: Remove and clean/replace the pre-motor and HEPA filters. Severely clogged filters can cause overcurrent.
- If it still shuts off quickly: The main motor or motor driver on the PCB may be shorted. Do not continue to run it; contact a Nilfisk service center.
