4 Reasons Why Your Dishwasher Isn’t Cleaning Dishes Well

There’s nothing more frustrating than opening your dishwasher to find that your “clean” dishes still have bits of food, residue, or white spots on them. If your dishwasher isn’t cleaning dishes properly, it can be due to a variety of issues. We’ll show you the most likely reasons why your dishwasher is leaving residue on dishes, not cleaning glasses properly, or not cleaning the bottom rack. We’ll also provide helpful tips on how to resolve these issues and maintain a sparkling clean dishwasher.

Here’s Why Your Dishwasher Isn’t Cleaning Dishes Properly

It might seem like your dishwasher is broken when clean dishes come out dirty, but don’t worry! One of these solutions may be the key to restoring your dishwasher’s cleaning power.

Improper Loading Can Lead to Poor Cleaning Performance

One common reason why your dishwasher isn’t cleaning dishes effectively is improper loading. Overloading, nesting, or not placing items in the right spots can prevent your dishwasher from doing its job. The water and detergent need to reach every surface of your dishes to clean them effectively, so it’s essential to load them correctly.

Here’s how you can load your dishwasher properly:

  1. Avoid overloading: Ensure that there’s enough space between items for water and detergent to reach all surfaces. Overloading can prevent proper water circulation, leading to unclean dishes.
  2. No nesting: Space out cutlery like spoons so they don’t nest together. Place items like bowls and cups at an angle to prevent nesting, which can trap water and leave residue. Make sure dishes don’t touch each other, allowing water and detergent to reach every surface.
  3. Load the bottom rack: Place larger, dirtier items like pots, pans, and plates on the bottom rack, ensuring they don’t block the spray arms. Blocked spray arms can cause dishwasher not cleaning bottom rack issues.
  4. Top rack for smaller items: Use the top rack for glasses, cups, and smaller items to prevent the dishwasher from not cleaning glasses properly.

Detergent Issues Can Cause Dishwasher Woes

Using the wrong amount of detergent, the wrong type, or having a broken dispenser can lead to your dishwasher not cleaning dishes properly. It’s crucial to use the right detergent and the correct amount to ensure your dishes come out sparkling clean.

Here’s what to do:

  1. Add the correct amount: Follow the manufacturer’s recommendations for the right amount of detergent. Too much can cause residue, while too little may leave dishes dirty. Adjust the amount based on the level of water hardness in your area.
  2. Use the right detergent: Make sure you’re using a detergent specifically designed for dishwashers. Regular dish soap can create excessive suds, hindering cleaning performance. Consider using tablets or pods, as they often contain the right mix of detergent, rinse aid, and other cleaning agents.
  3. Check the dispenser: If your dishwasher leaves dishes dirty, make sure the detergent dispenser is functioning properly and not blocked or broken. Clean the dispenser regularly to prevent buildup and ensure proper detergent release.

Clean Your Dishwasher for Better Performance

A dirty dishwasher can be the culprit when your dishwasher isn’t cleaning dishes. Cleaning your dishwasher filter and tub regularly can improve performance and prevent unpleasant odors. This maintenance step is essential to ensure your dishwasher stays in top shape.

Here’s how to clean a dishwasher filter and tub:

  1. Remove and clean the filter: Locate the filter at the bottom of the dishwasher, remove it, and clean it with warm soapy water. Make sure you remove any food debris or buildup. This should be done every few weeks or more frequently if needed.
  2. Clean the dishwasher tub: Run an empty cycle with dishwasher cleaner or white vinegar to remove residue and mineral deposits. Do this every month or as needed based on your dishwasher usage.
  3. Check and clean the spray arms: Inspect the spray arms for clogs or debris that can affect water pressure. To unclog a dishwasher spray arm, use a straightened-out paper clip or small brush to remove any blockages from the holes. Ensure the spray arms can rotate freely and are securely attached. Clean them as needed to maintain optimal performance.

Insufficient Water Supply Can Hamper Dishwasher Performance

If your dishwasher isn’t cleaning dishes, it might be due to insufficient water supply. Proper water supply and temperature are crucial to achieving clean dishes. If there’s an issue with the water supply, your dishwasher may struggle to perform efficiently.

Here are some common causes and solutions:

  1. Water not hot enough: Ensure that your water heater is set to the recommended temperature (120°F or 49°C) for optimal cleaning. Running hot water at the kitchen sink before starting the dishwasher can help ensure the dishwasher begins with hot water.
  2. Clogged spray arm: As mentioned earlier, a clogged spray arm can reduce water pressure. Make sure you unclog and clean the spray arms regularly to maintain proper water circulation inside the dishwasher.
  3. Faulty water inlet valve: A malfunctioning water inlet valve can restrict water flow. If you suspect this is the issue, consider contacting a professional for repair. A trained technician can diagnose and fix the problem, ensuring your dishwasher receives the correct amount of water.

Now you know the common issues that can cause your dishwasher not to clean glasses properly or leave dishes dirty. By following these tips and maintaining your dishwasher, you can help ensure that it continues to provide excellent cleaning performance.
