Four Reasons to Buy an LG Dishwasher

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 and Amazon Alexa, 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.

Purchased this a month ago and have loved it and all itÕs features. The third rack adds a lot of space as well as the foldable racks. Only reason itÕs not 5 stars is I wish it had a heat dry option.

Love it

First LG product I have purchased. Easy to install. Super quiet. Had to put my ear on the door to hear it. Washes dishes perfectly. Took a little getting used to placing dishes in racks however diminished with each use. So far very happy with purchase.

I bought this dishwasher along with all the matching appliances due to a remodel. I have had problems with this since basically day one as it never really dries all the way. Right after purchasing it, I contacted service because there was always water dripping down the inside door when I open it and dishes were still damp. They had me up the amount of rinse aid that was being dispersed during the appropriate cycle. It helped it somewhat but still moisture in the DW. BTW I set it on auto, high temp and extra dry. So I have since been just putting up with the small amount of dampness. I have had it since December and now it sometimes does not turn on even though I can see the numbers count down and then I have had it where it stopped in the middle of one cycle as there was water in the bottom of the DW when I opened it the next morning. I cannot depend on it anymore. I ran a load and left town and when I came back it was super damp in there so I'm concerned of mold growing so now I can no longer leave it and come back days later. Another complaint is they say to just scrape off food and do not rinse. Did that once and will never do that again! Had to hand wash my dishes! I would not purchase this again!
