Washer-dryer combo leaves visible detergent residue or white streaks on clothes after washing.

Safety first: No internal electrical work is required for basic correction; unplug only if accessing internal parts.

Step-by-step checks:

• 1. Adjust detergent use: Use high-efficiency (HE) detergent and reduce the amount, especially for soft water or small loads.
• 2. Use warmer water or extra rinse: Select a warmer wash temperature and enable an extra rinse option to improve detergent removal.
• 3. Clean dispenser drawer and housing: Remove and clean the drawer and housing to ensure proper dilution and flow.
• 4. Run a maintenance cycle: Periodically run a hot wash with no laundry to clear residue from the tub.

When to call a technician: If residue persists despite proper detergent use and cleaning, there may be underlying water flow or control issues needing professional evaluation.
