Kitchenaid Dishwasher Error Codes

Kitchenaid Dishwasher Error Code 6-4 or F6E4

If your KitchenAid dishwasher displays Error Code 6-4 or F6E4, it signals a problem with the float switch. The float switch is a critical component that monitors the water level in the dishwasher. This error occurs when the float switch remains in the open position, indicating a potential overfill situation.

  1. Stuck Float Switch: The float switch may be stuck in the open position, possibly due to debris or a mechanical issue.
  2. Obstruction Under Float Switch: An item or debris may be lodged under the float switch, preventing it from returning to the closed position.
  3. Faulty Inlet Water Fill Valve: The water fill valve responsible for controlling the water supply to the dishwasher may not be shutting off properly when the dishwasher is off, leading to an overfill situation.

Troubleshooting Steps:

  1. Inspect the Float Switch:
    • Locate the float switch in the bottom of the dishwasher.
    • Check for any visible obstructions or debris that may be preventing the float switch from moving freely.
    • Manually move the float switch to ensure it moves smoothly.
  2. Clear any Obstructions:
    • If an item or debris is found under the float switch, carefully remove it to allow the switch to return to its proper position.
  3. Check the Inlet Water Fill Valve:
    • Ensure the dishwasher is unplugged.
    • Locate the inlet water fill valve and inspect it for any signs of damage or malfunction.
    • Verify that the water supply to the dishwasher is shutting off completely when the dishwasher is not in use.
  4. Professional Assistance:
    • If the float switch is clean, moves freely, and there are no issues with the water fill valve, it’s advisable to seek professional assistance.
    • A certified technician, like those at Appliance Repair Los Angeles, can perform a thorough examination, identify the root cause, and make the necessary repairs or replacements.

Addressing Error Code 6-4 or F6E4 promptly ensures the proper functioning of your KitchenAid dishwasher.
