Quick Specs
Stainless Steel Touch Panel with LED Display
Sleek controls make it easy to select the settings you want, while the LED display provides every detail at glance.
LoDecibel(TM) Operation (38dB)
Doing the dishes shouldn't keep you up at night. LG's technological advances, like the Inverter Direct Drive Motor and self-cleaning filtration system, were designed with quiet in mind. At 38dB, this dishwasher is our quietest on the market.
QuadWash(TM)
The QuadWash(TM) with Multi-Motion spray arms combined with the Inverter Direct Drive motor power cleans dishes from multiple angles to reach every nook and cranny.
Height adjustable 3rd rack
The height adjustable 3rd rack gives you more space to fit everything from long flatware to small espresso cups.
Textured Steel(TM) Finish
The LG SIGNATURE dishwasher merges the exquisite Textured Steel(TM) Finish with our sturdy and sophisticated LG stainless steel technology.
TrueSteam(R)
LG TrueSteam(R) saves the time and headache of prewashing or rewashing dishes by hand. 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.
