Description & Features

LG LDP6797ST Built-In Dishwasher

 

Baked-on messes are no match for the LG LDP6797ST built-in QuadWash™ dishwasher. With four spray arms, this dishwasher makes your dishes sparkle with the first wash. The EasyRack™ Plus racking system allows you to customize rack spacing, so you can load tall wine glasses or pots with ease. Best of all this dishwasher is so quiet when it’s on, you will not even hear it running.

 

The stylish design of this stainless steel dishwasher is enhanced with an integrated top control panel, add a touch of sophistication to your kitchen. Its beautiful smudge-proof door opens to reveal a three-rack system with 15-place setting capacity, so you can wash more dishes in a single load. If you do not have a full load of dishes, that’s not a problem either with the Half Load cycle.

 

To ensure the ideal amount of water is used for optimal cleaning, LG equipped this dishwasher with sensors to detect the wash load. Once the wash load is detected, the dishwasher will use the ideal amount of water, so you do not have to worry about wasting an excessive amount of water.

 

With the LG LDP6797ST dishwasher you can conquer dishes the first time. The cutting-edge QuadWash™ system uses multi-motion spray arms that rotate back and forth while spinning to deliver maximum water coverage to both the top and bottom racks.  There is nowhere for dirt and baked-on messes to hide. The QuadWash™ system is so powerful, you can skip the pre-wash and load your dirty dishes as-is.

 

Eliminate the guesswork and achieve sparkling clean dishes, free from water spots with the Auto Cycle. The AutoCycle uses sensors throughout the washtub to detect the amount of dirt and debris on your dishes. Once the sensors have finished evaluating the load, the machine will automatically select the ideal wash settings to get the job done right the first time.

 

With the ThinQ™ app, you can receive notifications on your smartphone when your dishes are clean. You can also connect your dishwasher to Google Assistant or Amazon Alexa to use voice commands to turn on your dishwasher whenever you want or reorder detergent, so you never run out.

 

When you invest in the LG LPD6797ST dishwasher, you have the peace of mind of knowing your dishwasher will continue to serve you for years to come with the 10-year manufacturer’s warranty on the direct drive motor. LG engineers the direct drive motor with fewer moving parts and no belts for a more powerful cleaning performance that requires less energy. With fewer moving parts, there are fewer pieces that can break. In the event something does go wrong, LG has covered. 

 

If you are on the market for a new dishwasher for your home, look no further than the LG LDP6797ST built-in dishwasher. With 15-place setting capacity, the powerful QuadWash™ System, and autosensing capabilities you know this LG is one you can trust for many years to come.


Certified to Sanitize

All LG dishwashers are certified by the National Sanitization Foundation (NSF) to reduce bacteria found on dishes by 99.999% and reach a final rinse temperature greater than 150°F when operated on the Steam cycle of TrueSteam dishwashers or the High Temp Cycle of other LG dishwashers*. So you can clean and sanitize your dishes with confidence.


Get a Spotless Clean the First Time

LG's exclusive QuadWash™ technology gets dishes clean the first time. With four spray arms instead of just two, QuadWash™ uses Multi-Motion arms that rotate back and forth while spinning to power-clean dishes from multiple angles throughout the entire cycle.


Beautiful tables start with beautiful dishes

Dynamic Dry™ technology on all LG dishwashers delivers faster, more complete drying. So you get drier dishes for a more dynamic table.


Save Time and Simplify Your Everyday

The ThinQ app gives you a notification when your dishes are clean and even works with Alexa or Google Assistant.


A Clean You Can Count On for Years to Come

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


More Flexibility Means No Dish Gets Left Behind

EasyRack™ Plus lets you fit more dishes, run fewer loads and make short work of after-dinner cleanup. With three height settings, the upper rack adjusts effortlessly and smoothly to make room for tall stemware on top or oversize pans below. Customizable tines offer greater flexibility for loading dishes of all shapes and sizes without compromising cleaning performance.


So Quiet, You Can Use Your Indoor Voice

Now you can run the dishwasher whenever you want-day or night. The 44 dB cleaning cycle is whisper-quiet, so you won't have to worry about interrupting post-dinner-party conversations or naptime. Especially important for homes with open floor plans where sound readily travels from room to room.
