How to Fix / Troubleshooting
Safety first: Remove the battery pack before any disassembly. Do not run the motor if you smell burning or see smoke.
- Check for obstructions first: Ensure the dust bin, filters, and airways are clear. A locked rotor from debris can trigger motor faults.
- Listen for relay/driver click: With the battery installed, briefly press the trigger while holding the vacuum away from your face. If you hear a click but no motor spin, the motor may be seized.
- Inspect for burning smell: A strong burnt odor from the motor housing suggests internal motor failure.
- User‑level limit: Rowenta cordless motors are typically sealed units. Do not attempt to open the motor casing.
- Service path: If E8 persists after confirming no blockages, the motor or driver PCB must be replaced as an assembly. This requires opening the main body and should be done by a qualified technician.
