Brown or white marks are almost always caused by limescale build-up or the wrong water being used, rather than a fault with the iron. This is a maintenance issue, not a defect.
- Brown marks – Often mineral deposits or residue inside the iron. Run the self-clean or descaling programme to clear the build-up. Always check your user manual.
- White marks – Usually from minerals in the water supply. Empty and rinse the tank regularly, and use the recommended water type for your model.
Because water guidance varies by model, always check your user manual for the correct advice. Perfumed or additive waters should never be used, as they can damage the iron and increase limescale.
Care Tip: Empty the tank after each use and descale at regular intervals to prevent mineral build-up and keep your iron performing like new.
