What causes a turbidity sensor to fail?

Turbidity sensors can fail due to mineral buildup, debris accumulation, or electrical malfunctions over time. Exposure to harsh detergents or very hard water can also contribute to sensor degradation.

Where is the turbidity sensor located in a dishwasher?

The turbidity sensor is typically located in the sump area at the bottom of the dishwasher tub, often near the main pump or drain hose connection. Access usually requires removing the lower spray arm and filter assembly, or working from underneath the dishwasher.

Can I clean a turbidity sensor instead of replacing it?

In some cases, mineral buildup on the sensor lens can be carefully cleaned with a soft cloth and mild detergent. However, if the sensor has an internal electrical fault, cleaning will not resolve the issue, and replacement is necessary.
