How to Fix / Troubleshooting
Safety first: Immediately turn off the robot and unplug the dock. Do not continue using the robot until the cause is identified.
- 1. Allow cool‑down: Let the SilverCrest robot cool for at least 30 minutes in a ventilated area.
- 2. Inspect brushes: Remove main and side brushes. Clear all hair and debris from shafts and bearings.
- 3. Clean filters and vents: Clean or replace filters and ensure all ventilation slots are free of dust.
- 4. Test briefly: Run the robot for a few minutes while monitoring for smell. If odor returns quickly, stop use.
- 5. Replace suspect motor: Identify whether the smell comes from the brush area, fan exhaust, or wheels. Replace the corresponding SilverCrest motor assembly and have the main PCB inspected if any signs of burning are visible.
