  • Features
    • Hard Food Disposer: false (This feature has blades to chop and disintegrate hard food particles, making them small enough to easily drain away. This prevents them from being recirculated back onto dishware and allows for easy maintenance.)
    • Drying Method: Heated drying (Appliances that use heat to dry the dishes will include a heating element or minerals which transform moisture into heat. A fan or vent then circulates the hot dry air throughout the tub during the drying cycle. This may reduce drying time and the risk of water spots. Appliances that use minerals to produce heat are considered more energy efficient than those that include a heating element. Appliances that use condensation drying are considered more energy efficient than those that use heated drying. Instead, high temperature water is produced during the final rinse cycle which warms the interior and eventually condensates and drains out of the machine.)

Q: Middle rack will not go all the way back on the right side causing the inability to close door Unit install less that 7 days ago

A: I had the same problem too after a few weeks of install. I find that gently pulling out the middle rack all the way out helps to reset the drawers and allowing it to slide all the way back so that I can close the door.

Q: Is this unit supposed to ship with the sound insulation? They forgot it and it’s LOUD.

A: There should be a thick sound insulation blanket over the top and sides of the washer, our washer is unbelievably QUIET-much more quiet than dishwasher we’ve ever owned, including Bosch and Kitchen Aid.

Q: Can you place plastic items on the bottom rack, or will the dry boost melt plastic items?

A: I put plastic cover for covering food in the microwave on the bottom rack with no problem.

Q: Does this dishwasher use wifi?

A: The LG Smart Top Control Dishwasher with 1-Hour Wash & Dry, QuadWash® Pro, TrueSteam®, and Dynamic Heat Dry™, Model # LDTH7972S is a Wi-Fi-enabled dishwasher...^Ivan.

Q: What are the packaged dimensions? Like before it’s taken out of the box.

A: Hello there! Thank you for your inquiry. We're happy to provide you with the packaging or carton dimensions of the LG LDTH7972S. The dimensions are 28" x 34 3/4" x 29 5/8" (in) for width, height, and depth respectively. Additionally, the shipping weight of the product is 109.13 lbs.

Q: Do the 3 lights in the front door mean anything? do they light up a certain color when the cycle is done.

A: The green light will light after cycle is complete. The red light will light if there is some sort of error in addition to an error code being displayed where the cycle time would normally be displayed. As far as the other light I dont know since I have never seen that one.

Q: Does this model LDTH7972S have the auto open feature

A: No, but it does have a "night dry" function which circulates air if the dishwasher will remain closed for hours after cycle completion. Dishes and plastics come out dry and fresh.

Q: Interior light. Is there a way to turn the interior light off or does it time out and turn off after a period of time? Sometimes we like to leave the dishwasher cracked open to indicate clean dishes in addition to drying them.

A: The light times out and turns off. There is also a "night dry" function which circulates fresh air after cycle completion so you don’t have to open the door if you don’t want to. Dishes and even plastics come out dry and fresh.
