Dishwasher Not Cleaning? Perhaps Your Dishwasher Spray Arm is Clogged

Your dishwasher works wonders to keep your dishes clean — but over time, its interior parts, like the spray arm, can clog from a buildup of food, soap, and mineral deposits. If your dishwasher spray arm is clogged, it won’t be able to distribute water evenly throughout the dishwasher during a cycle.

How Do I Know If My Dishwasher Spray Arm Is Clogged?

If your dishes are coming out dirty or you notice low water pressure, your dishwasher spray arm may be clogged. If your dishwasher is struggling to operate, inspect the spray arm for any potential clogs.

How to Check For a Dishwasher Spray Arm That's Clogged

  • Open your dishwasher and find the spray arm. Some dishwashers only have one, which you can find at the base of the compartment. In some cases, your dishwasher may have one at the bottom and one under the top tray.

    To remove the spray arms, hold the arm at the center point, then twist and pull gently. It should twist off.

  • Look closely at the spray arm(s). All the holes should be clean and clear of debris. If you see food or dirt in the holes, your spray arm needs to be unclogged.

    If the holes look clean, you may be overloading your dishwasher. Washing too many dishes at once or distrubuting them unevenly can also affect the spray arm's ability to distribute water properly.

If a clogged spray arm doesn't seem to be the issue, consider other reasons for dirty dishes.

What To Do If Your Dishwasher Spray Arm Is Clogged

When your dishwasher spray arm is clogged, it’s best to go ahead and clean it. You can use a toothpick to carefully scoop out any food buildup or run the spray arm under hot water. Make sure to remove big pieces of food from your dishes before placing them in the dishwasher racks to prevent future clogs.
