Steps to Clean a Clogged Spray Arm

1. Safety First

Ensure the dishwasher is turned off and unplugged for safety. This prevents any accidental injury or damage to your appliance.

2. Access the Spray Arm

Remove the lower dish rack to access the spray arm. Depending on your dishwasher model, the spray arm may lift off or need to be unscrewed. Consult your user manual for specific instructions.

3. Inspect the Spray Arm

Inspect the spray arm for any visible debris, food particles, or mineral buildup in the spray arm holes.

4. Clean the Spray Arm

Rinse the spray arm under warm running water to remove loose debris.

Use a soft brush or toothbrush to scrub the outside and inside of the spray arm.

Use a toothpick or needle to carefully poke through each hole to clear any clogs. Be gentle to avoid damaging the plastic.

(Optional) If there is significant mineral buildup, soak the spray arm in a solution of vinegar and warm soapy water for about 30 minutes. Then, scrub again.

5. Reassemble

Once clean, reattach the spray arm and ensure it’s secured properly.

6. Replace the Lower Dish Rack

Put the dish rack back in its place.

7. Test the Spray Arm

Plug the dishwasher back in and run a short cycle without dishes. Observe if the spray arm is functioning properly.

Maintenance Tips to Prevent Clogs

Regular cleaning and maintenance can help prevent future clogs. Here are some tips to keep your spray arm in good condition:

1. Check and Clean Regularly

Regularly check and clean the spray arm to prevent future clogs. This should be done as part of your routine dishwasher maintenance.

2. Use Dishwasher Cleaner or Vinegar

Your most common source of clogging is calcification or lime build-up from hard water deposits. Consider using Lemi Shine detergent if you have hard water. Additionally, use a dishwasher cleaner or cleaning cycle every month or two to clear lime deposits. This should help your spray arms and extend their lives.

By following these steps, you can ensure your dishwasher's spray arm stays clean and functioning optimally, leading to better cleaning results and extended appliance life.
