Depending on the selected programme, the droplet-shaped design, with asymmetrical paddles gently rotates your laundry to the centre - regardless of the rotation direction. This not only ensures an intensive clean for more heavily soiled clothes, but a quicker, more thorough clean for the entire load. | Cardan Drive: adjust the height of the back feet of your built-in washing machine easily from the front With our Cardan Drive system, installing your built-in washing machine is super easy.

Slide the machine into your kitchen unit, then simply adjust the feet easily from the front with a screwdriver. | Programme for gentle cleaning of dark-coloured laundry, such as jeans.
