A blast of steam at the start of the cycle penetrates and dissolves tough caked-on food, but is gentle enough for your favorite wine glasses. A second blast during drying helps eliminate water spots by up to 60%1- no more having to wipe spotty glasses before guests arrive.



Quad Wash

The QuadWash™ with Multi-Motion spray arms combined with the Inverter Direct Drive motor power cleans dishes from multiple angles to reach every nook and cranny.
