AI Sensor Dry^®

Built-in Intelligence Takes Out The Guesswork

Forget about endless sorting or toggling through cycles—built-in sensors use AI technology to detect fabric texture and load size, then automatically select the right drying motions, temperatures and more for advanced fabric care. AI Sensor Dry^®detects moisture levels and automatically adjusts drying time for loads of all sizes—no more damp clothes, no more overdrying. With Smart Pairing, the washer can even tell the dryer to select a compatible drying cycle*, making it the ultimate laundry hack.
