Whirlpool Dishwasher turbidity sensor / optical wash sensor; also identified as soil sensor and thermistor W11410464, Replaces W11126174

Genuine Whirlpool OEM sensor that detects wash-water soil level and optical turbidity; the assembly may also provide temperature-sensing functionality to help control dishwasher cycle duration and temperature.

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Poor cleaning results when wash-water soil sensing is inaccurate.
• Wash cycles may run for an inappropriate duration or fail to optimize cycle timing.
• The dishwasher may continue operating with a default cycle if the turbidity-sensor circuit is not functioning.
• Some applications may show poor drying performance when the sensor assembly or its circuit is faulty.

Check Before Replacing

• With electrical power disconnected, inspect the sensor connector and wiring for looseness, corrosion, pin damage, or visible breaks.
• Inspect the sensor and surrounding sump area for heavy soil, obstruction, physical damage, or a displaced seal.
• Use the dishwasher’s model-specific service-mode or diagnostic procedure to check the turbidity-sensor circuit before replacing the component.
• Do not perform live-voltage or circuit-board measurements unless qualified to work safely on energized appliances; sensor symptoms can also result from wiring or control-board faults.

Pro Tip

Part Details

Key Features

• Genuine Whirlpool OEM optical wash/turbidity sensor.
• Also identified as a soil sensor, OWI sensor, or sensor-and-thermistor assembly in retailer and service documentation.
• Mounted under the dishwasher tub at the sump with retaining clips on documented Whirlpool-family platforms.
• Provides optical-output sensing for wash-water clarity; some documented assemblies also include temperature-sensing functionality.

Installation Notes

• Disconnect electrical power before servicing and shut off the dishwasher water supply before moving or accessing the appliance.
• Access is typically from beneath the tub after removing the appropriate access components for the specific dishwasher model.
• Disconnect the sensor wiring connector before removing the old sensor.
• On documented installations, the sensor is released from the sump by operating its retaining clips or rotating it counter-clockwise; install the replacement in the reverse orientation appropriate to the model.
• Inspect and correctly seat the seal before reassembly; a properly seated seal is important to prevent leakage.
• Restore panels, water, and power, then run the model-specific service or verification procedure.
