Possible Causes
How to Fix / Troubleshooting
Safety first: Turn the robot OFF and remove it from the dock. Do not open the main body unless you are qualified; this may void warranty.
- Hard reset: Turn the main power switch off (if present), wait 2 minutes, then turn it back on. Alternatively, hold the power button for 10–15 seconds to force a reset (model dependent).
- Check for moisture: If the robot was recently used on a damp floor or exposed to spills, allow it to dry in a warm, dry room for 24 hours before retrying.
- Update firmware: If your Dyson robot connects via Wi‑Fi/app, open the Dyson app and check for firmware updates. Apply any available update and reboot the robot.
- Dock power check: Ensure the dock power supply is original Dyson and delivering correct voltage. A failing adapter can cause unstable logic power.
If F6 persists after reset and firmware update, the main control PCB is likely faulty and should be replaced by an authorized Dyson service center.
