Four Reasons to Buy an LG Dishwasher

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.

  • Height Adjustable 3rd Rack

    Global_XD3 QuadWash_2017_Feature_08_HeightAdjustable3rdRack

    The height adjustable 3rd rack gives you more space for hard-to-fit items.

  • Smooth Operator

    Global_XD3 QuadWash_2017_Feature_08_SmoothOperator

    Even your hardest dish loads glide in and out smoothly with the help of LG’s Glide Rail.


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.


What People Are Saying

Rated 4 out of 5 by from It cleans well I really only have one problem with it, it takes way longer that I would like it to clean. My dishes come out spotless, which is a huge plus, but it just takes too long. It is extremely quiet. My daughter went into the kitchen to turn it on and hadn't realized it was already on. Plus I am able to turn it on with my phone. The middle rack is easy to use. Inlike that ALL of the plate/cup holders may be moved down so that I may fit my pots without bending anything out of shape. The third rack is also very convienient to place all of my larger spoons. Overall, I do very much like this appliance.

Rated 4 out of 5 by from Super Quiet Overall I am please with this dishwasher. Very quiet and seems to wash the dishes well. Wish the second rack had a little more height.....I guess the 3rd rack reduces the height. I installed it myself and it was easy to do and the instructions were well written. Documentation could be better

Rated 5 out of 5 by from great choice This dishwasher is the best we've owned, and even better than we expected!

Rated 3 out of 5 by from Great features but I bought this dishwasher several months ago but waited until I tried several options before commenting. The manual recommends that you not rinse the dishes but they don’t come clean if I don’t. Also the control panel developed a crack and had to be replaced since it’s made of plastic. This is of concern since I don’t have a clue why it happened and if the plastic cracked within a few months what should I expect in the future. Otherwise very stylish and the wi-fi feature is wonderful to trouble shoot or just find out you need more ride aid. I don’t know how to use all of these features and the directions are not clear to me in some instances.

Rated 5 out of 5 by from our second LG home appliance and we are as happy & satisfied as the first! The design of the product makes every function very efficient. The absolute most quiet Dishwasher ever!

Rated 5 out of 5 by from Slimline look. Quiet. The first time I used it I didn’t think that it was working because it was so quiet compared to my other machine. The bad thing is that the SmartThin Q self self diagnostic only works with a Samsung phone and not an Apple phone. I asked customer service when I couldn’t get it to work on my phone. But I love the clean look and it cleans efficiently.

Rated 4 out of 5 by from Three shortcomings Controls are hidden by the counter top and are not accessible without opening the door. Three hours to complete the cycle is double what it should be. Top rack should be completely smooth. (risers are of no value)

Rated 4 out of 5 by from Looks pretty. Cleans well. Didn't get dish washer until after Christmas, so experience limited. Takes a little time to find good arrangements for dishes. A little noisier than expected.

I can't start my dishwasher. Filled rinse agent, put in detergent pod selected power on, auto, start.....rinse aid icon flashes and will not start.  Set rinse to 3 as I have hard water....WILL NOT START! Rinse agent icon continues to flash and it is Full!

Asked by: Gramm
We regret to read about the issues that you are experiencing with your LG Top Control Smart wi-fi Enabled Dishwasher with QuadWash™, Model # LDP6797BD and apologize for any inconveniences. The dishwasher is equipped with an automatic error-monitoring system that detects and diagnoses problems at an early stage. Check to see if you have any error codes showing on the display. If the Rinse Aid light is still blinking after you have filled the rinse aid compartment, the dishwasher may need a hard reset. But before you do a hard reset, make sure that the door is closed and latched properly. Check that the Control Lock hasn't been inadvertently activated. Pressing and holding Half Load and Energy Saver simultaneously for three seconds will activate or deactivate this function. To do a rest, because the dishwasher is hardwired as opposed to being plugged into an outlet, resetting it will have to be done from the circuit breaker box or fuse box. You will need to locate the breaker that is allocated to the dishwasher and switch it off for about 15 seconds, then turn it back on again. If that does not resolve the blinking light, you will need to contact our Support Center at (800) 243-0000 for assistance with arranging for a repair service...^IFV

Is it normal to have about 1/2 inch of water in the drain after the cycle is finished?

Asked by: JanetA
If water remains in the tub after a cycle is completed, this usually is a sign that the drain hose is clogged or kinked. To fix, adjust the hose or clear blockage. ^CP

Does this dishwasher reguire a outlet? My old dishwasher was straight wired into the house electric....

Asked by: NDRjax
The LG Top Control Smart wi-fi Enabled Dishwasher with QuadWash™, Model # LDP6797BD has to be hardwired to a properly grounded branch circuit which is protected by a time delay fuse using the 3-wires, including a ground wire as your older dishwasher was connected. If an outlet is used, it must be in an accessible location adjacent to and not behind the dishwasher and within 4 feet (1.2 m) of the dishwasher's side...^IFV
