LG Dishwashers: Dynamic Heat Dry with AutoVent Dry

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Finally a 1-hour cycle that actually works

jrods 11/24/2025

This LG dishwasher is a massive upgrade. The two things that really stand out to me are the 1-Hour Wash Dry and the AutoVent. Unlike my old machine the 1-hour setting actually gets dishes clean and completely dry. The AutoVent feature pops the door open slightly at the end of the cycle to let steam escape meaning even my plastic containers come out bone dry goodbye puddles on my Tupperware Its also super quiet which is really important to me since I work in my kitchen and sits perfectly flush with my cabinets. Highly recommend I received this product in exchange for an honest review. Everything expressed here is my personal view.

JAB28 11/19/2025

I am a friend of an LG employee and I received this product for free in exchange for my honest review. All opinions expressed in this post are personal and should not be attributed to LG. Im very happy with this dishwasher so far. The look is sleek easy to read display. The 1 hour cycle is awesome especially with the holidays approaching. Great for between courses Large capacity with flexible options for loading since the spindles can be put down for odd shaped or oversized dishes. The blast zone for bottles is a great feature. The interior light is fantastic love that. Dishwasher is very quiet when it runs and the door self opening feature at the end of a cycle promotes quicker and complete drying. Dishes come out sparkling All in all a great product.

Overall Im very satisfied with this dishwasher. It cleans well runs quietly and feels solidly built. I also appreciate the useful features like enough capacity an adjustable middle rack and the top layer thats perfect for small or flat items. Design-wise its sleek fully touch-based and even opens automatically when the cycle is finished. It offers multiple wash options ranging from quick cycles to heavy loads. Overall I highly recommend it.

Rebec17 11/18/2025

I am a friend of an LG employee and I received this product for free in exchange for my honest review. All opinions expressed in this post are personal and should not be attributed to LG. Im really happy with this dishwasher. I love that the spindles fold down so I can fit all my oddly shaped items and the top rack is perfect for small things and lids. The BottleZone feature is amazing for water bottles and kids cups it actually gets them clean inside which was a constant struggle with my previous dishwasher. The wash performance is so great and the 1-Hour Wash Dry is super convenient when we are running around and need a fast cycle in between childrens activities The AutoVent Dry leaves everything dry without that damp feel. I was surprised at first that the machine opens itself at the end of a cycle but it really helps release the steam and all my dishes dry so well Genius Overall its easy to load cleans really well and has features that actually make a difference. I barely even know its running because its so quiet Super impressed

Great features and flush design

AMG8789 11/17/2025

This dishwasher is amazing It fits perfectly in my kitchen. So much so that it doesnt hit the cabinet handles unlike my previous dishwasher which had a pocket handle. The 1-hour cycle and BlastZone are so quiet that I didnt even notice it was finished until I saw the floor status light Im also pleasantly surprised with how vibrant the interior LED lights are.

GIOK2 11/17/2025

I am a family member of an LG employee and I received this product for free in exchange for my honest review. All opinions expressed in this post are personal and should not be attributed to LG. First of all I love the design and color. It also lines up nicely with my cabinet doors. The interior is large featuring three trays that slide very smoothly easily fitting a daily load of dishes. The noise level is minimal when it runs I hardly notice it operating. The touch screen on top is easy to navigate and the options are pretty clear. The regular cycle takes a little over two hours while the one-hour mode is very useful when I am in a rush. I have only used it for a week so it is early to tell the exact energy efficiency but the energy guide sticker shows a yearly consumption of a little over $30 which is very low cost. Installation was simple fast and nicely done by the LG service team. The ThinQ app is another great feature that makes it easy to track the cycle maintenance and receive any alerts. Overall it has great performance and I am looking forward to enjoying it further.

We received delivery of our new LG dishwasher today and I couldnt be more impressed The quality of the appliance is outstanding and the entire delivery and installation process was seamless. The delivery team even took away our old non-working Bosch dishwasher which was incredibly convenient. A big thank-you to Angela for making this possible and to the entire LG team for providing such an excellent product and service.
