Lower Spray Arm

Hello Marlene, Thank you for your inquiry. We show the blue spinner wheel comes with the part. To replace it, you would just need to remove the lower dishrack, and then pull up on the lower spray arm to remove it, then align the new spray arm on the support and snap into place and replace the lower dishrack. We hope this helps and if you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you!
