ENERGY STAR Certified

Products that earn the ENERGY STAR label meet strict energy-efficiency specifications set by the U.S. EPA, helping you save energy and money while protecting our climate by making choices that count for a clean energy future.

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.

Hybrid Condensing Drying System

Innovate beyond a traditional heating element. This LG dishwasher combines heat generated during the final rinse with the cooler walls of the stainless steel tub to turn moist air into water droplets that simply drain away. Dishes are dry and ready to unload without using extra energy or extending drying cycles, plus your plastic utensils and containers are safer from heat and harm.

Dual Zone

LG Dual Zone technology varies the water intensity in the upper and lower racks -- delicate dishes in the upper rack have a softer setting while pots and pans in the lower rack are washed with stronger intensity.This enables you to accommodate different items in the same load for added washing convenience.

Half Wash Mode

Want clean dishes, but don't want to wait for a full load? This feature saves water and energy by letting you wash only items in either the lower or upper rack.

PrintProof Finish

PrintProof finish resists fingerprints and smudges to keep your kitchen looking its best. Available in black and classic stainless steel, now you can have all of the things you love about stainless steel appliances—the premium look, the professional-grade durability—without the need for special cleaners or constant attention. Plus, it easily wipes clean with a soft, dry cloth.
