Washer leaves visible detergent or powder marks on clothes after washing.

Safety first: No internal work is required for this issue; follow usage adjustments.

• Use correct detergent: Use high-efficiency detergent suitable for front-loaders and follow SMEG's dosing guidelines.
• Increase temperature: For heavily soiled loads, use a warmer program to help dissolve powder.
• Clean dispenser: Ensure the drawer and housing are free of caked detergent.
• Select extra rinse: Use the extra rinse option if available for sensitive skin or heavy detergent use.

If residue persists, consider switching to liquid detergent and verifying that the washer is filling and rinsing correctly.
