Customer Questions and Answers for Turbidity Sensor (Dishwasher) by Frigidaire

This dishwasher turbidity sensor measures how dirty the wash water is and reports to the control. Replacing a faulty sensor can restore proper cycle times and cleaning performance for consistent results.

• Monitors water clarity/soil level during the wash
• Sends feedback to the control to adjust cycle length, rinses, and heating
• Failure can cause very long or very short cycles
• Can trigger sensor-related fault indications

• Disconnect power at the breaker and shut off water before servicing
• Access the sensor from the bottom near the sump; remove the toe panel if needed
• Unplug the wire harness; release the locking tabs or twist-lock to remove; avoid touching the optical window
• Inspect and reuse the existing seal/retainer if in good condition; seat fully and check for leaks after reassembly
