Optical turbidity sensor that detects soil level or water clarity in dishwasher water and sends that information to the control board.

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Cycles may run unusually long or short.
• Dishes may remain poorly cleaned when the sensor does not accurately detect wash-water soil.
• The dishwasher may repeat draining and refilling or fail to advance normally when the control receives an implausible water-clarity reading.
• An Aqua Sensor-related fault may be indicated on models that monitor this sensor.

Check Before Replacing

• Confirm that the symptom occurs on a cycle that uses water-clarity sensing; do not assume every dishwasher-cycle problem is sensor-related.
• With power disconnected, inspect the sensor connector and accessible wiring for looseness, corrosion, pin damage, or obvious damage.
• Inspect the sensor's optical area and nearby sump/pressure-chamber area for heavy soil or debris; clean only as permitted by the appliance's service documentation and avoid abrasive tools or chemicals.
• After service, restore the water and electrical supplies and check for leaks during a supervised test cycle.
• Use the dishwasher's model-specific service documentation for any electrical or diagnostic-mode test; do not condemn the sensor from symptoms alone.
