About this Item

Overview

Smart Top Control Dishwasher with 1-Hour Wash & Dry, QuadWash Pro, TrueSteam, and Dynamic Heat Dry

Our leading 1-hour wash and dry cycle gives you sparkling, table-ready dishes in less time High-pressure jets with 38% more cleaning power, as compared to our standard QuadWash. Built In Leak Detection monitors water supply, drainage and drainage and leakage When the dishwasher is not in use, the Hidden LED Front Timer disappears for a sleek look. The height-adjustable 3rd rack provides space to fit everything from long flatware to small cups.

Features:

1-Hour Wash & Dry
LG's exclusive QuadWash Pro and Dynamic Heat Dry technologies combine to deliver the industry's leading 1-hour wash and dry cycle* for sparkling, table-ready dishes in less time. So you can spend more time on what matters.

Dynamic Heat Dry
Our Dynamic Heat Dry technology circulates hot air throughout the dishwasher for faster, more complete drying*, delivering sparkling, table-ready dishes right off the rack. Disclaimer: *as compared to LG dishwashers without Dynamic Heat Dry technology.

QuadWash Pro
Tackle post-dinner cleanup like a pro with the enhanced cleaning power of QuadWash Pro. High-pressure jets with 38% more cleaning power*, spray dishes from multiple angles, while soaking them with over one million microbubbles to help break down stubborn food residue and provide exceptional cleaning performance.

TrueSteam with Sanitization
LG TrueSteam uses the power of steam to penetrate food residue and help eliminate water spots by up to 60%*. Plus, LG dishwashers are certified by the National Sanitation Foundation to reduce bacteria on dishes by 99.999% and reach a final rinse temperature greater than 150°F when operated on the Steam cycle** for peace of mind.

Remote Start
Conveniently start your dishwasher remotely with the ThinQ app, so no matter where you are, your dishes will be ready when you need them.

ThinQ Auto Leak Detection (2024)
ThinQ monitors water supply, drainage and leakage and will notify you if any issues arise after installation.* Built right in for worry-free operation. Compatible models will alert you as soon as there is an issue.*

10-Year Manufacturer's Limited Warranty on Inverter Direct Drive Motor
LG's efficient Inverter Direct Drive motor has fewer moving parts and no belts for a powerful cleaning that uses less energy and saves you money. It performs so reliably that it's backed by a 10-year manufacturer's limited warranty for added peace of mind. Plus, the quiet operation won't disrupt your day.

Disclaimer: *Based on 2022 third-party testing comparing competitive consumer products.
Disclaimer: *as compared to our standard QuadWash
Disclaimer: *Percent in water spot reduction compared to comparable LG non-steam dishwasher on delicate wash cycle. Results may vary by model. Results based on test with LG LDF7774ST as of Feb. 2018. **Certified by the National Sanitation Foundation (NSF) to reduce bacteria on dishes by 99.999% when operated on the Steam cycle.

Rated 5 out of 5 by from Scrape don’t rinse This dishwasher is awesome. Cleans like non I have owned before. Scrape do not rinse is a real thing with this model. Glasses sparkle, dishes crusted with egg yoke come shinny clean. I really could not be happier with the performance of this machine.

Rated 5 out of 5 by from very pleased with this dishwasher. [This review was collected as part of a promotion.] Had this now for couple months. Very quiet, cleans very well. Dries very well. For intallation, the little push in plastic knobs over the side holes for attachment to side frame are a little unknown how well they will hold up. They seem very flimsy for keeping water out of the sides of washer. Time will tell

Rated 5 out of 5 by from I hour wash is all we need [This review was collected as part of a promotion.] have had this a couple of months now and it does a great job.

Rated 5 out of 5 by from Best Dishwasher This dishwasher does an excellent job of cleaning dishes/glasses/pots/pan/silverware/etc. Easy to understand and use the various features which you can tailor to the job at hand. An added plus, it is very quiet when in operation; in fact, you almost can' t tell it is running unless you get close and listen carefully. Its interior design is practical/functional/very accommodating to all kitchenware. The exterior design is sleek and attractive.

Can't find this exact model (LDTH7972D) on display. On the display models I could see... when opening... the door falls to the ground... no tension! Is this normal?

Asked by: doug
Hi Doug. The door on this LG Smart Top Control Dishwasher with 1-Hour Wash & Dry, QuadWash® Pro, TrueSteam® and Dynamic Heat Dry™, Model # LDTH7972D does not "fall to the ground" when opening it, but it is parallel to the ground when opened fully. Please visit our site at https://www.lg.com/us/dishwashers/lg-ldth7972d-top-control-dishwasher# to view images of the dishwasher with the door open...^Ivan
