Washer leaves clothes with residue or white streaks after washing

Safety first: No internal electrical work is usually required for this issue.

Steps to reduce residue:

• Reduce detergent: Use the amount recommended for your water hardness and load size; modern Siemens machines need less detergent.
• Use liquid detergent: In cold washes, liquid detergents dissolve better than powders.
• Clean dispenser: Ensure the drawer and housing are free of caked powder.
• Use extra rinse: Activate the extra rinse option for heavily soiled or large loads.

When to call a technician: If residue persists despite correct dosing and cleaning, water inlet or control issues may need investigation.
