Possible Causes and Solutions:

1. Improper Loading:
   - Cause: Overloading the dishwasher can obstruct water spray, preventing proper cleaning.
   - Solution: Arrange dishes so water can reach all surfaces. Avoid blocking spray arms, and make sure plates and utensils aren't nesting.

2. Clogged Spray Arms:
   - Cause: Accumulated debris can block spray arm nozzles, reducing water distribution.
   - Solution: Remove spray arms and clean nozzles. Run water through them to ensure clear flow.

3. Unclean Filters:
   - Cause: Dirty filters hinder water circulation, affecting cleaning performance.
   - Solution: Regularly clean filters according to the manufacturer's instructions.

4. Faulty Water Temperature:
   - Cause: Insufficient hot water can prevent effective cleaning.
   - Solution: Verify water heater temperature settings. It should be around 120°F (49°C) for optimal performance.

5. Wrong Detergent or Amount:
   - Cause: Using the wrong detergent or too little detergent can lead to poor cleaning.
   - Solution: Use a high-quality dishwasher detergent and follow manufacturer guidelines for proper dosage.

6. Blocked Drain Path:
   - Cause: A clogged drain can hinder drainage and re-deposit debris on dishes.
   - Solution: Inspect and clean the drain path, including the filter, pump, and drain hose.

7. Mineral Buildup:
   - Cause: Hard water can cause mineral buildup on dishes, making them appear dirty.
   - Solution: Use a dishwasher cleaner regularly to prevent mineral deposits. Consider a water softener if your area has hard water.

8. Worn or Broken Spray Arms:
   - Cause: Damaged spray arms may not distribute water evenly, resulting in incomplete cleaning.
   - Solution: Replace worn or broken spray arms as needed.

9. Faulty Water Inlet Valve:
   - Cause: A malfunctioning water inlet valve can lead to inadequate water supply.
   - Solution: Test the valve for proper operation and replace if necessary.

10. Grease or Food Residue in Dishwasher:
    - Cause: Grease or food debris in the dishwasher can affect cleaning performance.
    - Solution: Regularly clean the dishwasher's interior, including the door, walls, and racks.
