Upper rack dishes remain dirty while lower rack is mostly clean.

Safety first: Turn off power before removing racks or spray arms.

• Remove and clean arm: Detach the Fagor upper spray arm and rinse thoroughly, clearing all jets.
• Check feed tube: Inspect the vertical feed tube and rear water port for obstructions or misalignment.
• Rack position: Ensure the upper rack is pushed fully back so the feed tube engages the rear port.
• Replace arm: If the arm is cracked or the bearing is worn, replace the upper spray arm assembly.
