Imagine coming home after a busy day, unloading your dishwasher, and everything from delicate champagne flutes to plastic snack boxes is dry, spotless, and ready to be used. No damp plastic containers, no steam clouds fogging up your kitchen, and no need to grab a tea towel for last-minute drying. With our patented Zeolith® drying technology, this is your new reality.

Intelligent technology, inspired by nature

The magic of Zeolith® Drying technology lies in a remarkable natural mineral that absorbs moisture and converts it into heat energy. It requires no maintenance and lasts the entire lifetime of the dishwasher.

How Zeolith® Drying works

During drying, a fan directs steam into a chamber where it is absorbed by the zeolite crystals. This process generates heat which speeds up drying. At the start of the next wash cycle, the zeolite is heated, releasing the stored moisture so the crystals are ready to perform again.

Three cutting-edge drying technologies

When it comes to drying your dishes, Siemens offers three levels of technology, each tailored to different needs.

Good: Heat exchanger

These dishwashers use a pump to recycle heat for efficient, eco-friendly performance.

Better: openDoor
