Dishwasher Troubleshooting: Dishwasher Not Cleaning Dishes

Is your dishwasher not cleaning as well as you'd like? Regular maintenance can help your dishwasher clean thoroughly and efficiently. Try the tips below to help troubleshoot and maintain your dishwasher:

1. Clean the filter regularly (located at the bottom of your dishwasher). Review your owner's manual to learn how to remove it. Wash it with soap and a soft brush under running water to remove debris. To learn more, view our 'How to Clean Your Dishwasher Filter' video on our How-to Video page

2. Load the dishes properly ensuring there's adequate space between items. Make sure the spray arms aren't blocked by tall items. Learn how to load your dishwasher and adjust the upper rack and the flex tines on our How-to Video page.

3. No need to pre-rinse dishes before loading. Just make sure the food is scraped off the dishware. Detergent needs small food debris to cling to in order to work properly.

4. Add rinse aid. Review your owner's manual to learn how and where to add the rinse aid. Rinse aid helps water droplets slide off dishware and improves drying. To learn more, view our 'How to Add Rinse Aid' video on our How-to Video page

5. Clean your dishwasher's spray arms and ensure they're not clogged. Rinse them under water to see if any of the holes are blocked. If they are, use a toothpick to loosen any debris caught in the holes. To learn more, view our 'How to Clean Spray Arms' video on our How-to Video page
