midea | dishwasher – Spray Arm/Diverter Error – Water Not Circulating Properly
Error Codes (nE): Troubleshooting, Fixes & Prevention Tips explained below.

What Does Spray Arm or Diverter Error Mean❓

The Spray Arm or Diverter Error indicates that water is not circulating properly inside the dishwasher. This usually happens when the spray arms are clogged, stuck, or when the diverter valve fails to redirect water correctly between spray levels. Without proper water flow, the dishes may remain dirty, and the appliance may display an error or stop mid-cycle. This issue can arise from mechanical blockages, pump failure, or debris interfering with internal components.

dishwasher - Common Causes of Spray Arm or Diverter Error

  • Clogged spray arm holes due to food debris or hard water deposits.
  • Spray arms not rotating due to blockage or improper installation.
  • Faulty diverter motor or valve not switching water direction.
  • Malfunctioning circulation pump failing to create water pressure.
  • Foreign objects obstructing moving parts inside the dishwasher.

dishwasher - Steps to Fix Spray Arm or Diverter Error❓

  • Inspect the Spray Arms

    1. Remove the spray arms from the dishwasher.
    2. Check for food particles or mineral deposits blocking the nozzles.

  • Clean or Replace the Spray Arms

    1. Rinse under running water or use a pin to unclog blocked holes.
    2. Replace the spray arms if they are cracked or damaged.

  • Check the Diverter Valve

    1. Access the diverter motor or valve (usually beneath the tub).
    2. Ensure it rotates freely and is not stuck or obstructed.

  • Test the Circulation Pump

    1. If there’s no water movement, the circulation pump may be faulty.
    2. Use a multimeter or technician service to verify the pump’s operation.

dishwasher - Helpful Tips to Prevent Circulation Issues

  • Rinse large food particles off dishes before loading.
  • Clean spray arms monthly to prevent buildup.
  • Use dishwasher cleaner regularly to avoid hard water residue.
  • Avoid overloading the racks, which can block spray arm rotation.
  • Do not block the lower spray arm with oversized pots or trays.
