White streaks after an EW6S404WP wash usually come from undissolved detergent, excess dose or a drum packed too tightly. Keep the diagnosis at user level: record the exact stage, change one condition at a time and do not open the cabinet. Low temperature and restricted fabric movement leave powder or concentrated liquid on folds instead of dispersing it through the rinse. Chalky or soapy marks that rinse away are detergent residue; bleached pale patches that remain are chemical damage. Brush off dry excess, rinse affected items, reduce the next load and detergent dose, choose a temperature that dissolves the product and add an extra rinse if needed. Test a small dark load. If residue returns with correct dosing and free drum space, clean the drawer and request support if it persists.
Models covered
Safety first

What the symptom may indicate
Checks in the right order
- Confirm before acting
Low temperature and restricted fabric movement leave powder or concentrated liquid on folds instead of dispersing it through the rinse.
- Make the appliance safe
Cancel the programme, unplug the washer, close the taps and let retained water cool. Never force a locked door or lid, bypass an interlock or remove a panel.
- Apply the official check
Brush off dry excess, rinse affected items, reduce the next load and detergent dose, choose a temperature that dissolves the product and add an extra rinse if needed.
- Retest once and decide
Test a small dark load. If residue returns with correct dosing and free drum space, clean the drawer and request support if it persists.
Stop and get qualified help when
- Stop for water under the washer, a damaged hose, burning smell, a hot plug, violent metal noise or a symptom that returns after the single documented test.
Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
