  • Flex Zone
    Flex Zone lets you customize your cleaning to target different zones inside the dishwasher. Set it to wash only the upper rack or only the lower rack, based on where the load is.. Or, adjust the wash intensity to soft for the upper spray arm and strong for the lower, for just the right amount of pressure on each level.
