Maintenance
Cleaning the Soleplate

- Ensure the appliance is unplugged and completely cool (at least 2 hours after use).
- Unscrew and remove the anti-calc collector, typically located on the side of the steam generator base.
- Rinse the collector thoroughly under running water to remove all limescale deposits.
- Reinsert and screw the collector back into its position until it is securely tightened.
