CreativeKamau, thank you for asking. Let's get the details you need.
This dryer features a setting called Sensory Dry, which detects the moisture level in the load and stops the dryer when the load reaches the desired dryness level, thereby minimizing excess energy use.
Please refer to your user manual for more details. Turn to page 38, "Sensory Dry," and page 39, "Sensor Dry cycles."
