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.

What People Are Saying

Rated 4 out of 5 by from Middle rack does dry completely Most of the latest mid- to high end ranged dishwashers are introducing similar functions like a 3rd rack, quiet running, collapsible racks, etc. The LG, however, does a poor job of drying cups, bowls, or pretty much anything that's not a plate on the top 2 racks. Even on the High Temp and Extra Dry settings, there's always pools of water on top of my glasses and mugs. Yes, I use Jet Dry rinse aid.

Rated 5 out of 5 by from Quiet, cleans very well and looks great Bought this machine the day before Thanksgiving. We were so glad that Lowes had one in stock. It took about 45 minutes to install and everyone was inpressed with it on Thanksgiving Day but no one was more thankful than I. So far we have been vvery inpressed with it. The third shelf on top has been wonderful and is used every time we run the dishwasher. We also like tha light that comes on inside the dishwasher every time we open the door.

Rated 4 out of 5 by from Great deal for the price.. Been using it for 2 months now. Dishes come out clean and dry. runs nice and quiet. Needed to read manual to understand the controls. Disk rack is a little flimsy, have to push it in the middle or it binds when full and some of the dish holders seem to flop over a little too ease. Wife loves the light inside.

Rated 5 out of 5 by from Oh So Quiet and my dishes are clean! Bought this from our local Lowe's several months ago and we are very satisfied with this purchase. This dishwasher is so quiet, that sometimes I have to check the lights to see if I started it. Dishes are clean and sparkling. Love that the dishes are dried without the need of a heating element, no more melted plastics or burnt wooden spoons that accidentally fall to the bottom. As long as I keep the Jet Dry compartment full, our dishes are bone dry after each cycle. The racks are so easy to use and I love that I can configure them in any way to get my job done. I will never use a utensil basket again after having the 3rd rack. I love how clean my silverware is and it is so easy to load and unload. We look forward to using this dishwasher for many years.

Rated 5 out of 5 by from Easy to use and is very quiet. We have had the dishwasher for a few weeks and it has been run every 1 or two days. We love the third rack. I was afraid that we would have wet plastic dishes with the lack of heating element but have found it does a fantastic job of getting most of the water to evaporate. It dries just as good as our old dishwasher that had a heating element. The lights inside the tub are great.

Rated 3 out of 5 by from Works well but noisy This dishwasher works well but is noisier than we were told it would be. I had a hard time connecting the app and didn't really understand why and what purpose it serves anyway. It came with a scratch in the handle and it looks like it happened. in shipping. It seems to be built well and does clean better than our previous dishwasher.

Can I use soap tablets?

Asked by: Ltdedt
The LG Black Stainless Steel Series Top Control Dishwasher with QuadWash™ and EasyRack™ Plus, Model # LDT7797BD is designed with a main wash compartment that ypu need to add liquid dishwasher detergent to so it can be dispensed at the correct time during a wash cycle. Incorrect detergent may cause the dishwasher to fill with suds during operation. Excess suds may reduce wash performance and may cause the dishwasher to leak. If using detergent tablets, do not use liquid rinse aid since they already include rinse aid. For further instructions on their use with the dishwasher, please refer to the instructions on the packaging or contact the manufacturer...^IFV

Does this model have the ability heat the water beyond the temperature that the main house water heater is set at? My dishes are never very hot or clean at the end of a cycle even when using high temp. I'm wondering if I just have a defective unit.

I am shopping for a new dishwasher. Is LG’s “Delicate” cycle safe for china and crystal or do I look for a specific model that says China/Crystal?

Asked by: EMH52
Hello, the delicate cycle in our unit should be used to clean delicate items such as fine china and stemware.

1)Does the stainless steel exterior hide finger prints? 2) what is the Electrical current

Asked by: Double TT
The Stainless Steel on this LG Top Control Dishwasher with QuadWash™ and EasyRack™ Plus, Model # LDT7797ST is not fingerprint or smudge resistant. Not sure if when asking about the "Electrical current" for this unit you are asking about its Electrical requirements or the current which is measured in amperes? The Electrical Requirements are 120 V, 60 Hz AC only and a minimum 15 Ampere circuit breaker...^IFV
