Dishwasher leaves white powder or detergent residue in dispenser or on dishes

Safety first: Allow the dishwasher to cool before inspecting the dispenser.

• Check spray arm alignment: Ensure the upper spray arm is not blocked and can spray directly toward the dispenser area.
• Clean dispenser: Wipe the detergent compartment and ensure the door opens freely without obstruction from dishes.
• Load correctly: Avoid placing large items directly in front of the dispenser door.
• Verify heating: Confirm that water heats properly; if not, address heater issues as in E3.
• Replace dispenser: If the door does not open during the cycle, replace the detergent dispenser assembly.
