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.

It looks good on the outside, but doesn't fit my personality. I'm too old to understand all the settings. My old dishwasher did a great job until the control panel went out. I have a problem with the soap dispenser not releasing the Cascade pouch. Asked the mfg. for help and was told that maybe the upper rack was down too low and was preventing it from opening. It is in the highest position.

Great Cleaning

I bought this when my 17 year old maytag dishwasher stopped working, definitely high end dishwasher, but the controls on top are hard to tell if you have actually pushed them and they are slow to respond, had to re-boot it under direction of customer service. Very Quiet!!! and seems to wash the dishes well so far.
