J.D. Power Award Winner

"Highest in Customer Satisfaction with Dishwashers"


Put Enhanced Cleaning in Motion

Achieve maximum cleaning throughout the entire cycle with LG QuadWash . With four spray arms instead of two, QuadWash also includes Multi-Motion arms that rotate back and forth while spinning. The high pressure jets power-clean dishes from multiple angles.


Think you have to check on the dishes" Think Again

LG smart dishwashers come with SmartThinQ® technology built-in, so you can get smartphone notifications when a cycle is complete. That means less waiting and more time to yourself. You can even check on the cycle status with voice commands using the Google Assistant, so you don't have to lift a finger.


Count On It

When you buy a dishwasher, you want something reliable that you can count on. Because the Direct Drive Motor uses fewer moving parts and operates more efficiently, LG confidently backs the motor with a 10-year warranty.


Easy Loading & Maximum Flexibility

The newly-enhanced EasyRack Plus system provides outstanding flexibility and convenience, adjusting to just about any load of dishes to help ensure optimal cleaning performance. Easy to adjust on-the-fly, this racking system can shift to handle any challenge your dishes can serve up.


Quiet Operation

LG's technological advances, like the Inverter DirectDrive motor and the advanced self-cleaning filtration system, were designed with quiet in mind. At 44dB, this dishwasher is among the quietest dishwashers in its class.

We recently had our LG dishwasher installed and although we havent used many of the features much were amazed at how quiet and efficient if has been. There is ample space for dishes and I love love the top shelf although need to figure out the compromise between weird fitting things and my wine glasses.

Used 3 Times and It Failed.

LE Paul 12/12/2017

Washed dishes 3 times before it failed with a LE error code on Thanksgiving day with a full load of dishes. The LE error code indicates that the motor has failed. It has been nearly 3 weeks and the dishwasher has not been repaired because the service center is still waiting for parts that are on backorder. I asked LG and Home Depot to replace the dishwasher but they both refused.
