What is a dishwasher turbidity sensor?

A dishwasher turbidity sensor is an optical sensor that measures how cloudy or dirty the water is during a wash cycle. It uses infrared light to detect food particles and debris, helping the dishwasher optimize cycle time and water temperature for efficient cleaning.

Can I clean a dishwasher turbidity sensor instead of replacing it?

While some minor debris might be cleaned from the sensor, a faulty turbidity sensor typically requires replacement. Mineral buildup or electronic failure often prevents it from functioning correctly, and cleaning may only offer a temporary or no solution.

How does a faulty turbidity sensor affect dishwasher performance?

A faulty turbidity sensor can lead to several issues, including dishes not getting clean, cycles running too long or short, or excessive water use. Without accurate water clarity data, the dishwasher cannot properly adjust its wash settings, impacting overall cleaning effectiveness.
