How to Fix / Troubleshooting
Safety: Disconnect from mains before extended resets.
- Hard reset: Unplug the carpet cleaner for at least 15 minutes to allow capacitors to discharge and the control to fully reset.
- Check for stuck buttons: Inspect the control panel for any buttons that may be stuck pressed, which can cause boot errors. Free them gently.
- Restore default settings: If the user menu allows, perform a factory reset or restore default settings as described in the user manual.
- Surge protection: Connect the unit via a surge-protected outlet to prevent future firmware corruption.
- If error persists: The main PCB may require reprogramming or replacement. This should be done by an authorized Miele service center.
