Why Your Dishwasher Leaves Dishes Dirty (And How to Fix It)

# Why Your Dishwasher Leaves Dishes Dirty (And How to Fix It)

Nothing is more frustrating than unloading the dishwasher only to find dishes still covered in food. Here's why this happens and what you can do about it.

Common Causes and Solutions

1. Clogged Spray Arms Food particles can block the spray arm holes. Remove the spray arms and clean them with a toothpick or small brush. Run water through them to clear any debris.

2. Dirty Filter Most dishwashers have a filter at the bottom that needs regular cleaning. Remove it and rinse under running water. Clean weekly for best results.

3. Wrong Detergent or Too Little Use quality dishwasher detergent (not hand dish soap!) and ensure the dispenser is full. Consider using pods for consistent dosing.

4. Hard Water Buildup Hard water leaves mineral deposits on dishes and inside the machine. Use a rinse aid and run a monthly cleaning cycle with dishwasher cleaner or vinegar.

5. Improper Loading Don't overcrowd or block the spray arms. Face dirty surfaces toward the center and angle items downward so water drains off.

6. Water Temperature Too Low Your water heater should be set to at least 120°F. Run the hot water at your sink before starting the dishwasher to ensure hot water enters from the start.

7. Old or Clogged Water Inlet Valve If the dishwasher isn't getting enough water, it can't clean effectively. Listen for the fill sound - if it's weak, the inlet valve may need replacement.
