Troubleshooting

Dishwasher Not Cleaning Dishes? Here's What to Check

Pulling out a dish that still has food on it after a full cycle is frustrating. Before assuming your dishwasher needs repair, check these five common causes first.

1

Clogged spray arms

Food particles and hard water buildup can clog the small holes in your spray arms. Remove them and clear any debris with a toothpick.

2

A dirty filter

Most modern dishwashers have a removable filter at the bottom. If it is clogged with food, dirty water recirculates onto your dishes.

3

Water temperature too low

Dishwashers need hot water, usually at least 120°F, to dissolve detergent and cut through grease properly.

4

Overloading the dishwasher

Packing in too many dishes blocks water and detergent from reaching every surface.

5

Old or clumped detergent

Detergent pods and powder can lose effectiveness over time, especially if stored in a humid area like under the sink.

Quick test: Run your kitchen sink faucet until the water gets hot before starting the dishwasher. This ensures the first fill uses hot water instead of whatever was sitting in the pipes.

When the problem needs a technician

If you have cleaned the filter and spray arms, checked your water temperature, and are still getting cloudy or dirty dishes, the issue may be a failing wash pump or a water inlet valve not delivering enough water pressure. These repairs require opening up the dishwasher and are best left to a professional.

How to prevent future cleaning problems

  • Clean the filter every 1 to 2 weeks depending on how often you run the dishwasher
  • Scrape large food scraps off dishes before loading, even with newer models
  • Run a monthly cleaning cycle with a dishwasher cleaner to remove buildup
  • Check that spray arms spin freely and are not blocked by tall items

Bosch owners: If you have CrystalDry technology and notice poor drying along with poor cleaning, the zeolite mineral tray may need attention. This is a Bosch-specific component our technicians are familiar with.

Every 1 to 2 weeks is ideal, depending on how often you run the dishwasher and what kinds of food scraps go down the drain.

Cloudy glasses are usually caused by hard water mineral deposits. A rinse aid and occasional vinegar cycle can help.
