@TechConnectify About the secondary video: I discovered that mine has such a turbidity sensor because it opens its door automatically (great feature by the way), sometimes way before the expected time. I was afraid there was some kind of malfunction (although dishes were mostly clean, save for the odd rice grains stuck in forks), so I called the manufacturer to clear that up, and they answered that the device leverages the sensor's data to finish early if there's nothing left to clean.
