Top rack dishes remain dirty while bottom rack cleans normally.

Safety first: Turn off power before removing spray arms.

• Clean upper spray arm: Remove and rinse the arm; clear all jets with a toothpick.
• Inspect feed tube: Ensure the vertical feed tube and connection to the upper arm are not cracked or disconnected.
• Load properly: Avoid blocking the upper spray arm with tall items.
• Diverter check: If water never reaches the upper arm, the Midea diverter may be faulty and require service.
