Product Details

Efficiency can mean a lot nowadays, and this dryer knows it. Its ultra large capacity will handle extra-large loads, so you finish your laundry faster. The Intelligent Electronic Controls with Dual LED Display make it easier to get the settings right, so you can just set it and go. The Sensor Dry System will detect the level of moisture in the fabric and automatically adjust drying-time and temperature. And, stay ahead of the cycle and access key LG dryer features remotely with SmartThinQ technology. If you appreciate efficiency, so does this dryer.
  • Do laundry a little less often. With 7.4 cubic feet of capacity, this dryer handles really large loads. Saving you time and effort.
  • LG dryers with SmartThinQ technology will change the way you think and the way you live. Imagine being able to remotely control key dryer features simply by downloading the free LG SmartThinQ app onto your Android or iOS device. Eliminate the guesswork and avoid wrinkles by extending the cycle time on your commute home or receive an alert on your smartphone when your favorite shirt is dry. You can even start the dryer with a voice command and never miss a moment of your favorite show. LG SmartThinQ technology works seamlessly with the voice-activated features of the Google Assistant and Amazon Alexa.
  • A lot of those drying headaches can be a thing of the past. Our TurboSteam Technology generates real steam to reduce wrinkles and odors, and practically eliminates the need for ironing.
  • Nothing is worse than pulling clothes out of the dryer and finding they're still damp. Our Sensor Dry system measures the moisture levels during the cycle and automatically adjusts the drying time, to help ensure you get dry laundry every time.
  • When pressed for time, pop your dry clothes in for a tumble on the Wrinkle Care Option to reduce creases.
  • Let's face it: Sometimes, you just don't have time to wait for a standard dry cycle. LG's SpeedDry Cycle can have clothes dry in just 15 minutes.
  • When your dryer uses about 20% less energy, youre going to make an impacton your utility bills, your energy consumption, and most importantly, the environment.
  • The FlowSense Duct Clogging Indicator will tell you when its time to clean the ducts out. Clean ducts mean a great drying every time.
  • Our tough steel drum becomes even more durable now that we've applied an advanced aluminized alloy coating. It helps protect the finish of the drum over years of use while maintaining its luster and attractive finish.
  • You probably wish you could clean your throw pillows or childrens toys. With the SteamSanitary Cycle, you can. It uses steam to safely sanitize items marked as non-washable.
  • Late for the party and no time to iron your favorite outfit? The SteamFresh Cycle refreshes, and reduces wrinkles in up to five garments at a time with one 20-minute dryer cycle.
  • If you ever experience an issue with your LG dryer, you don't have to worry. The SmartDiagnosis feature helps the service center diagnose problems over the phone, or with a simple app on your smart phone, helping you minimize costly, inconvenient service calls.
  • Say so long to static. The ReduceStatic Option virtually eliminates static cling.
  • No one likes ironing, the EasyIron option lightly moistens clothes to make ironing easier and more efficient
  • Let us take the guesswork out of doing the laundry. With features like our Dual LED Display indicators and intuitive Dial-A-Cycle controls, youll find the right setting every time.
  • Theres no need for laundry to be noisy. The LG LoDecibel motor: chances are you may not even notice it.
  • All compatible LG washers, dryer, SideKick pedestal washers, and laundry pedestals sold separately.

Answer This Question

A:  The ENERGY STAR® Qualified LG 7.4 cu. ft. Ultra Large Capacity Smart wi-fi Enabled SteamDryer™, Model # DLEX3700W is a stackable dryer. You will need the LG 27" Stacking Kit, Model # KSTK1 to stack it on a matching washer...^Ivan

    Q:We have a Model # DLEX35700V dryer that has TurboSteam options. Do we have to hook up dryer with a steam installation kit? Where can we find a hose that is 8ft long? We can only find 6ft hoses. Thank you!

    1 Answer
    Answer This Question

    A:  The ENERGY STAR® Qualified LG 7.4 cu. ft. Ultra Large Capacity Smart Wi-Fi Enabled SteamDryer™, Model # DLEX3700V comes with a long and short inlet hose and a "Y" connector that allows you to split the cold water supply line to your washer and to the water inlet valve on the dryer to supply water for the steam functions on the dryer. LG only makes replacement inlet hoses for the ones that come as included accessories with the dryer and we do not make longer inlet hoses. If you are looking for longer inlet hoses, you will need to purchase third-party inlet hoses and you will need to search online to see if third-party manufacturers offer inlet hoses longer than 6 feet. Regrettably, the U.S. will not have information for retailers in Ontario that sell inlet hoses...^IFV

          A:  When you bought the washer and dryer they should have given you the paper work for national grid . If not call your electric company a call. When you call your electric Company. You will need the model number and the date that you bought it. Good luck you bought a great washer and dryer.

              Clothes Destroyer
              We have owned this for about 6 months. The lint filter has not fit correctly. It does not fit flush with the rest of the surface--the filter housing than it sits in. One end of the filter sticks up high enough that clothing catches on it. As a result, the clothing hangs, then twists due to the other clothes and the drum spinning, and it tears the clothes. It's torn delicate items as well as permanent press items such as a dress shirt where it virtually tore the pocket in half. I don't know if the filter is flawed or the filter housing it sits in os/ It doesn't fit right. It needs either a new filter or housing. This shouldn't happen with a 6 month old dryer. A dryer is not supposed to destroy your clothing, pretty much the opposite of what you expect to happen. I've been reading responses from LG. Rather than a response that thanks me for this review and tells me they are learning due to them and that they understand, I want to know what they'll do to make it right. I have a houseful of LG stuff, but if this isn't resolved this will be the last item of theirs I'll buy. Other than destroying the occasional $50 shirt, it functions fine. I will amend this to a glowing review if this is resolved painlessly.

                I picked the LG because they’re products are supposed to be a great product but the machine does not clean our clothes. I constantly have to rewash clothes. Our undergarments don’t get clean or fresh. Our shirts come out of the wash still with deodorant stains. These clothes are not clean. We’ve had it for almost 7 months and should have returned it after the first wash.

                          Smart Machines
                          [This review was collected as part of a promotion.] This is our second set of LG machines. Second because when we sold our home we had to leave then behind. These new machines are just as nice as our last ones except much better. Love the Push Notifications when they are done! Not only do these machines talk to you, they talk to themselves. What I am getting at here is there is no actual voice, just the push notifications to you but they also set the dryer for the proper setting based on what the washer was set on. So If I select say Towels on the washer then when that is done and you put them in the dryer, the dryer will automatically set the dryer to Towels!
                            Great Washer
                            [This review was collected as part of a promotion.] I have both the washer and dryer and love them! We have a dog and are happy we can use the allergy setting to get rid of all the bad stuff the dogs blankets have accumulated. The washer is great. just takes time getting use to it compared to traditional model.
