1. Check for Obstructions in the Dishwasher

The first step is to ensure that there’s nothing blocking the arms from spinning. Here’s what you can do:

  • Empty your dishwasher entirely.
  • Manually spin the arms to see if they move freely.
  • Look for any dishes or utensils that might have fallen and blocked the arms.
  • Remove any obstructions you find.

2. Examine the Spray Arm Holes

Over time, debris and food particles can get trapped in the holes of the spray arms. This can affect their rotation. To clean them:

  • Remove the spray arms – usually by unscrewing or unclipping them.
  • Inspect the holes on each arm for any blockages.
  • Use a toothpick or a small brush to clear out any debris.
  • Rinse the arms under water and reattach them.
