Dishwasher displays F5; spray arms may not rotate and cleaning performance is poor.

Safety first: Disconnect power before removing spray arms or accessing the base.

• 1. Clean spray arms: Remove upper and lower spray arms. Rinse under water and use a toothpick to clear blocked jets, especially at the ends.
• 2. Check filters and sump: Ensure the filters are clean and properly seated. Inspect the sump for debris restricting water flow to the pump.
• 3. Listen to circulation pump: During wash, listen for a strong, steady motor sound and water spraying. A weak or intermittent sound suggests pump issues.
• 4. Inspect circulation pump: Access the Haier wash pump from the bottom. Check for leaks, overheating, or signs of wear. Test the motor windings and any external capacitor.
• 5. Replace pump if necessary: If the pump is noisy, seized, or electrically faulty, replace the circulation pump assembly.

Warning: Ensure all spray arms are correctly reinstalled; loose arms can damage dishes and the tub.
