Step 1: Check the Water Temperature

It’s essential to make sure your dishwasher is receiving hot enough water. Cold water won’t dissolve detergent properly, which can lead to residue. You can check the water temperature by running the hot water at the sink nearest to your dishwasher until it’s hot. Then, start the dishwasher.

Step 2: Examine the Dishwasher Detergent

Using old or clumped detergent can result in a dishwasher leaving residue on dishes. Check if your detergent is fresh and stored in a dry area. If it’s old or moist, it might be time to replace it. Remember, too much detergent can also leave a residue. Use the recommended amount stated on the detergent packaging.

Step 3: Clean the Dishwasher Filter

Your dishwasher filter needs to be cleaned regularly. A dirty filter can lead to residue on dishes. To clean the filter, remove it from the dishwasher (refer to your dishwasher’s manual if needed) and rinse it under warm water. Use a soft brush to remove any food particles stuck in the filter.

A clogged spray arm can also be the cause of a dishwasher leaving residue on dishes. To clean the spray arm, remove it by unscrewing it from the dishwasher. Then, clean the holes of the spray arm with a toothpick or wire to remove any blockages. Rinse the spray arm under warm water before putting it back.
