Frigidaire Dishwasher Error Code TU

If your Frigidaire dishwasher is displaying the error code TU, it signals a malfunction in the turbidity sensor. The turbidity sensor plays a crucial role in determining the clarity of the water during the dishwashing cycle. When this sensor fails, it can hinder the dishwasher’s ability to optimize water usage and detergent dispensing, affecting overall cleaning performance.

Troubleshooting Steps:

1. Inspect Wiring Connections: Begin by checking the wiring connections between the turbidity sensor and the main control board. Over time, connections may become loose or damaged, leading to communication errors. Ensure all connections are secure and free from any visible wear or tear.
2. Addressing Wiring Issues: If you identify any issues with the wiring, carefully address them. This may involve repairing damaged wires or securing loose connections. Take note of the color-coded wires and their respective placements to ensure accurate reconnection.
3. Testing for Continuity: Use a multimeter to test the continuity of the wiring. This step helps identify any hidden faults that may not be visible during a visual inspection. A lack of continuity indicates a break in the wiring and requires repair or replacement.
4. Replacing the Turbidity Sensor: If the wiring appears intact and the issue persists, the turbidity sensor itself may be faulty. Consider replacing the sensor with a new, compatible part. Refer to your dishwasher’s manual or Frigidaire’s official guidelines for specific instructions on sensor replacement.

Important Considerations:

• Precision and Care: When handling wiring and electronic components, exercise precision and care. Avoid using excessive force, and follow safety guidelines to prevent damage to the dishwasher or personal injury.
• Consult the Manual: Always consult your dishwasher’s manual for model-specific information and troubleshooting steps. Frigidaire’s official documentation provides valuable insights into error codes and recommended solutions.
• Professional Assistance: If you encounter challenges during the troubleshooting process or lack the technical expertise, consider seeking professional assistance. A certified technician can efficiently diagnose and address the issue, ensuring a reliable and long-lasting solution.

Resolving the Frigidaire dishwasher error code TU requires a systematic approach, focusing on both visual inspection and electrical testing. By following these steps, you can enhance your chances of identifying and resolving the turbidity sensor failure, restoring your dishwasher to optimal performance.
