Washing Cycles and Features
- AI Control: This intelligent system adapts to your preferences, suggesting up to 27 selectable programs and options you use most frequently.
- Ecodosatore (Auto Dispense): The integrated sensor system (water, weight, detergent) calculates the precise amount of detergent and softener for each load. The auto dispense system can last up to 1 month autonomously, reducing waste.
- Steam Wash: When activated, a powerful jet of steam is emitted from the bottom of the drum, removing stubborn dirt and 99.9% of bacteria and allergens for hygienically clean laundry.
- Turbo+: This feature reduces washing time by pre-mixing detergent with air bubbles, creating a foam that acts from the first minute of washing. The rinse phase is also faster and more effective.
- Eco Lavaggio (Eco Wash): Achieve cold washes like hot washes, saving up to 70% energy.
