How to Troubleshoot a Dishwasher That Isn't Cleaning Properly

When your dishwasher is not cleaning your dishes properly, there can be a variety of reasons. From improper maintenance to faulty components, identifying the issue can help you get your dishwasher back to its cleaning best. Below, we'll dive into the most common causes and detailed steps to troubleshoot them.

Check Your Maintenance Routine

Regular maintenance is key to ensuring your dishwasher functions correctly. Here are the steps you can take to improve the cleaning performance of your machine:

Clean the Filter: The filter can accumulate debris, which can obstruct water flow and prevent effective cleaning. Make sure to remove and wash the filter as recommended in your maintenance instructions. Tidy the Arms: The rotating sprayer arms can sometimes get clogged or obstructed. Refer to your specific model’s manual and YouTube tutorials to clean the spray arms. Use Separate Rinse Aid: Even if your detergent claims to include a rinse aid, it's good practice to use a separate rinse aid to ensure grease and water spots are minimized. Scrape Food Scraps: Ensure all food scraps are removed from dishes before loading the dishwasher. Lint and food bits can interfere with the cleaning process and clog the machine. Monthly Dishwasher Cleaner: Using a dishwasher cleaner once a month can help remove buildup and ensure better cleaning performance. Check Prewash Detergent: It's crucial to use detergent in the prewash cycle, especially if you're using tablet detergents. Proper Loading: Make sure the dishwasher is loaded correctly and that dishes are not touching. Full Load: Fill the dishwasher to capacity, but be sure not to overfill it. Overcrowding can hamper the cleaning process. Plates Separation: Ensure that plates are not directly touching. Proper spacing helps in achieving effective cleaning. Check Drain: Ensure the dishwasher is draining properly. Clogs in the drain can impair the cleaning process.

Common Issues and Solutions

There are several common issues that can cause your dishwasher to not clean properly. Here are some typical problems and the steps to resolve them:

Food Particles Blocking Screens: In some cases, food particles can clog the screens in the lower part of the dishwasher. Refer to your manual and watch online tutorials to clean these filters and reinsert them properly. Zip Ties and Shipping Locks: Brand new dishwashers may still have shipping locks on the wash arms. Make sure to check if any zip ties are impeding the movement of the arms. The arms should rotate freely. Insufficient Water Temperature: Ensure that your water is hot enough. If it's not, consider running hot water from the tap until it heats up and then start the dishwasher. Using a generic detergent can also cause issues, so opt for detergent specifically designed for dishwashers. Clogged Wash Arm Holes: Check for any clogs in the wash arm holes. Clogs can obstruct the water flow and cleaning spray, thus reducing cleaning efficacy. Inadequate Detergent Usage: Sometimes, the problem lies in not using enough detergent. Check your detergent application and usage.

Installation and Setup

If your dishwasher is brand new, make sure it was installed and set up correctly. Follow the installation and usage instruction booklet provided with the dishwasher. The instructions should include troubleshooting pages and checklists to help you identify and resolve any common issues.

Ensure the dishwasher has an adequate water supply, the correct electricity supply, and that the drain line can handle the flow of dirty water. Cleaning the filters and ensuring dishes are properly pre-rinsed and loaded can also greatly improve cleaning performance.

Conclusion

A properly maintained and correctly set up dishwasher can provide excellent cleaning results. By following the tips and troubleshooting steps outlined here, you can identify and resolve common issues that may be causing your dishwasher to not clean properly.

Remember to check your maintenance routine, watch online tutorials, and refer to your instruction manual for specific guidance relevant to your dishwasher model. With these steps, your dishes will be sparkling clean in no time!
