Why Is My Dishwasher Not Cleaning Properly: Common Troubleshooting Tips and Solutions

Why Is My Dishwasher Not Cleaning Properly?

If your dishwasher is not cleaning properly, the most common reason is a dirty or clogged filter.

Dishwashers have filters located at the bottom center, which can get clogged over time with regular use.

Cleaning these filters periodically will help maintain the dishwasher’s performance.

However, some Maytag dishwasher models feature Dual Power Filtration, which eliminates the need for routine maintenance as it filters and chops up food in the dishwasher.

Key Points:

  • Dirty or clogged filters are the most common reason for a dishwasher not cleaning properly.
  • Dishwashers have filters at the bottom center that can become clogged with regular use.
  • Cleaning these filters regularly is necessary to maintain the dishwasher’s performance.
  • Maytag dishwasher models with Dual Power Filtration eliminate the need for routine filter maintenance.
  • Dual Power Filtration filters and chops up food in the dishwasher.
  • Regular filter maintenance or the use of Dual Power Filtration will ensure proper cleaning performance in dishwashers.

Did You Know?

1. Did you know that the average dishwasher can use up to 3 to 5 gallons of water in a single cycle, while handwashing the same amount of dishes can consume up to 27 gallons? So, even if your dishwasher is not cleaning properly, it can still be more efficient than washing by hand!

2. One possible reason for your dishwasher not cleaning properly could be a clogged spray arm. These small, rotating arms distribute water throughout the dishwasher during the wash cycle. Make sure to check the spray arm and clean out any debris or mineral deposits that may be obstructing its movement.

3. Hard water can have a significant impact on your dishwasher’s cleaning performance. If you notice a buildup of limescale or mineral deposits on your dishes, it might be time to consider using a rinse aid or installing a water softener to improve your dishwasher’s efficiency.

4. It may not be your dishwasher’s fault if your dishes are not coming out as clean as they used to. Even some modern dishwasher detergents require certain minerals found in phosphates to be effective. Due to environmental concerns, many regions have banned the use of phosphates in dishwasher detergents, resulting in slightly less effective cleaning results.

5. Have you checked the dishwasher’s filter lately? This often-overlooked component can become clogged with food particles, preventing proper water flow and hindering the dishwasher’s cleaning performance. Regularly cleaning and maintaining the filter can significantly improve your dishwasher’s cleaning abilities.

Food Residue And Grit: Unclean Filter Causes Poor Dishwasher Performance

One of the most common issues that can cause a dishwasher to not clean properly is a dirty or clogged filter. Dishwashers are designed to remove food particles and debris from dishes, but over time, the filter can become filled with gunk and debris, preventing it from effectively doing its job. When this happens, it can result in dishes that still have food residue on them or feel gritty to the touch.

It is important to note that not all dishwashers have the same type of filter. Some may have a single filter that needs to be manually cleaned, while others may have multiple filters that can be easily removed and cleaned. Regardless of the type of filter your dishwasher has, regular cleaning is essential for maintaining optimal performance.

Solution: To address this issue, it is recommended to clean the dishwasher’s filter periodically. The frequency of cleaning may vary depending on the frequency of use and the amount of food debris that is typically present on your dishes. However, a general rule of thumb is to clean the filter at least once a month.

Maintenance Tip: Regular Filter Cleaning For Optimal Dishwasher Functioning

Regular filter cleaning is crucial for ensuring that your dishwasher is able to effectively remove food particles and debris from your dishes. If the filter becomes clogged, it can negatively impact the dishwasher’s performance, resulting in dishes that are not properly cleaned.


  • Start by locating the filter in your dishwasher, usually at the bottom center.
  • Remove the filter and rinse it under running water to remove any loose debris.
  • Use a soft brush to gently scrub the filter and remove any stubborn residue.
  • Once clean, reassemble the filter and place it back into the dishwasher.

Cleaning the filter regularly is essential for maintaining the dishwasher’s performance and ensuring that your dishes are properly cleaned.

Filter Location: Bottom Center – Easy Access For Cleaning

One of the benefits of most dishwasher models is that the filters are conveniently located at the bottom center of the dishwasher. This makes it easy to access and clean the filter, ensuring that your dishwasher is able to perform at its best.

Solution: To access the filter, simply open the dishwasher and remove the bottom rack. This will expose the filter, allowing you to remove it for cleaning. Make sure to follow the manufacturer’s instructions for removing and cleaning the filter to avoid causing any damage to your dishwasher.

  • Open the dishwasher and remove the bottom rack.
  • Remove the filter for cleaning.
  • Follow the manufacturer’s instructions to avoid damage.

Remember to follow the manufacturer’s instructions for safe and effective cleaning.

Frequently Asked Questions

Why are my dishes still dirty after dishwasher?

There could be a few reasons why your dishes are still dirty after running them through the dishwasher. Firstly, it is possible that the spray arm holes are clogged with debris, preventing proper water flow and distribution. To fix this, try cleaning the spray arm by soaking it in a mixture of vinegar and water, or by using a toothpick to clear any obstructions.

Another possible reason for the lack of cleanliness is mineral buildup in the dishwasher. This can happen over time and hinder the effectiveness of the dishwasher’s cleaning ability. To combat this, try running a cycle with citric acid or dishwasher cleaner to dissolve and remove any mineral deposits. Additionally, make sure to regularly clean and maintain the dishwasher filter and drain to ensure optimal performance.

What causes a dishwasher not to wash properly?

One common reason for a dishwasher not washing properly is a blocked filter. Regularly cleaning the filter is essential to maintain the dishwasher’s efficiency. Another potential culprit is a blocked spray arm, which hinders the water from reaching all the dishes. Low water temperature can also contribute to ineffective washing. Additionally, selecting the correct wash cycle and avoiding overloading the dishwasher can significantly impact its performance. Water hardness can also affect the dishwasher’s ability to clean effectively.

How do you clean your dishwasher so it cleans better?

To achieve a better clean in your dishwasher, you can try a simple and effective method. Start by placing a dishwasher-safe container filled with 2 cups (500 mL) of white vinegar on the lower rack. Proceed to run a normal cycle without using detergent or turning on the heat dry option. This process will help remove any built-up residue and leave your dishwasher refreshed and ready for optimal cleaning performance.

Another approach worth considering involves utilizing baking soda to enhance the cleaning efficiency of your dishwasher. Begin by sprinkling a generous amount of baking soda on the bottom of the dishwasher. Then, run a short cycle using hot water to allow the baking soda to work its magic in eliminating odors and removing stains. The combination of vinegar and baking soda proves to be a cost-effective and natural way to maintain a cleaner and more efficient dishwasher.

How do you run a clean cycle on a dishwasher?

To initiate a clean cycle on a dishwasher, ensure that it is emptied of any dishes or utensils. Following this, find a dishwasher-safe bowl and fill it with 1 cup of white vinegar. Position the bowl on the top rack of the dishwasher and proceed to run the dishwasher on the hottest cycle available. Once the cycle is complete, it is advisable to skip the drying cycle and instead open the dishwasher door, allowing it to air-dry naturally. By following these steps, your dishwasher will undergo an effective cleaning process, ensuring its continued functionality and cleanliness.
