Bosch 165279 Dishwasher Turbidity Sensor | Replaces 00165279, AP2802364, AH3439109, PS3439109

Dishwasher Turbidity Sensor – Bosch

The Bosch 00165279 dishwasher turbidity sensor measures the cloudiness of the wash water to determine how soiled the load is, allowing the dishwasher's control to automatically adjust cycle length and water temperature for optimum cleaning efficiency. When the sensor fails, the dishwasher may run excessively long cycles, very short cycles, or produce poor wash results because the control cannot correctly assess water soil level. This direct-replacement turbidity sensor restores automatic wash optimization on compatible Bosch dishwasher models.
