Product Overview

When you've got the power of steam, you've got the power to clean from serious grime to your most delicate fabrics. The Allergiene cycle uses gentle yet deeply penetrating steam to remove over 95% of pet dander allergens. Simplify your laundry to-do list and access key LG washer features remotely using SmartThinQ technology. And, master multi-taskers take note: This LG washer is TWIN Wash System compatible, which means you can add the ingenious LG SideKick pedestal washer to tackle two loads of laundry both large and small all at the same time.
  • Ultra-Large 4.5 cu.ft. Capacity Towers of towels, piles of sweatshirts, and a mountain of jeans? Go for it; the ultra-large capacity (4.5 cu.ft.) tub lets you do more laundry in fewer loads; that's time saved and sore backs avoided
  • LG washers with SmartThinQ technology will change the way you think and the way you live. Gone are the days of patiently waiting for the wash cycle to finish before tackling your laundry to-do list. Download the free app onto your Android or iOS device and time management becomes a breeze. Get alerts on your smartphone the minute clothes are clean, and control key washer features from anywhere, at any time. You can also start a load of wash with a simple voice command, since LG SmartThinQ appliances work with the Google Assistant and Amazon Alexa. Count on LG to give you a helping hand when you need it most
  • Steam Technology gently but powerfully penetrates fabrics to virtually eliminate dirt, odors and wrinkles
  • This LG washer is LG SideKick compatible, which means you can add the mini pedestal washer to your front load washer and now tackle two loads of laundry both large and small all at the same time. Now you can divide and conquer your laundry and whatever messy moments life throws at you
  • Get your clothes clean and experience a smarter way to wash with our innovative 6Motion technology. Each wash cycle combines up to 6 different wash motions to provide a revolutionary cleaning experience
  • The TubClean Cycle is designed for easy, periodic maintenance to keep your washer fresh. The cycle uses water jets to clean the wash tub and door, and an air dryer removes excess moisture, helping to keep your high-performing washer in tip-top condition
  • If you ever experience an issue with your LG washer, 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
  • When you buy a washer, you want something reliable that you can count on. Because the Direct Drive Motor uses fewer moving parts and operates more efficiently, LG confidently backs the motor with a 10-year limited warranty
  • This LG washer is certified as asthma and allergy friendly by the Asthma and Allergy Foundation of America (AAFA) a leading national nonprofit organization dedicated to those with asthma and allergies
  • LG LoDecibel operation is so quiet you may not even notice the washer running. In addition, TrueBalance anti-vibration system minimizes washer noise to help keep your laundry room and surrounding environment peaceful
  • The NeveRust wash tub is made of durable stainless steel, avoiding nicks that can snag fabrics
  • ColdWash technology uses cold water and enhanced washing motions to penetrate deep into fabrics, giving you cold water savings with warm water performance
  • When you need clean clothes fast, LG's SpeedWash Cycle can have small loads clean and fresh in just 15 minutes
  • SenseClean System automatically sets the water level and wash time for each load based on the weight
  • The spin cycle on this washer reaches up to 1300 RPM for a powerful spin. Which means more water extraction and less drying time
  • All compatible LG washers, dryer, SideKick pedestal washers, and laundry pedestals sold separately.
  • Choosing the FreshCare option periodically tumbles your clean laundry every few minutes; so even if your clothes sit in the drum for hours, they will be clean and fresh, as if the cycle just ended

Questions & Answers


Is the door reversible?

Asked by Chase1966 June 12, 2021

Like the doors for all our Front Load Washers, the door for the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Smart Wi-Fi Enabled Front Load Washer, Model # WM3700HVA is not reversible...^IFV

How do I set up wifi?  need step by step for iPhone.

Asked by EZ tech February 27, 2021

The ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Smart wi-fi Enabled Front Load Washer, Model # WM3700HVA supports 2.4 GHz Wi-Fi networks only. Check your network's frequency, or contact your internet service provider or refer to your wireless router manual. If the appliance is having trouble connecting to your Wi-Fi network, it may be too far from your router so you may need to purchase a Wi-Fi repeater (Range extender) to improve the Wi-Fi signal. Turn off the Mobile Data or Cellular Data on your smartphone and connect it to your wireless router. To verify the Wi-Fi connection for the washer, check that the Wi-Fi icon on the control panel is lit. Make sure that the security protocol is set as WPA2 (WEP will not work). Next, search for the LG ThinQ application in the Apple App Store and follow the instructions to download and install it on your phone. Should you need further assistance, please contact our Support Center at (800) 243-0000 for step-by-step guidance...^IFV

Which models currently available will stack on top of this unit?

Asked by James November 6, 2020

Hi, so units should not be stacked directly upon each other and need to be supported by a rack to keep from damaging the lower unit. That being the case any similarly sized unit you can purchase a rack for will work.

Good features, but could be more reliable
Bought this as a washer/dryer set two years ago. In general it has great features but about 6 months ago, we've noticed a tiny leak of water exactly where shown on the picture. Enough to trigger the water detection alarm and wet the parquet flooring on which it sits. I have reported this to LG with my extended warranty. They will come and repair it at some point it seems. I would have preferred not having to spend time in seeking a remedy to a product defect.

Was Great Machine
I was so excited to get my 1st front loader. My basement had just been remodeled & I had a pretty laundry area. A little over 2 years later the machine sounded like a jet propelled engine! The ball bearings had failed & it’s in need of a big overhaul. Thanks to My extended warranty I am getting a replacement for free!!

Excellent performance
Ease of use; Cleans clothes well; Like front-loader style as it uses less water, less soap and washes without causing wear on clothes.

Good Washer, Satisfied!
I am satisfied with my purchase of this washer. I read many reviews before purchasing and I decided to give it a try. It gets my clothes clean and fresh which I like and I must say that I find it to be very energy efficient. Despite seeing reviews of it having long wash cycles, I’ve come to realize that only happens once it’s a large load, and it’s necessary to get all the clothes clean. The steam option is a nice bonus I can tell the difference after using it where my clothes are extra fresh. This washer also saves me from spending too much on detergent (realized I was using too much with my previous top load washer). I’ve had it for a few months and it works fine, being able to download a few extra cycles as well is a plus. All that being said, I will also share what I dislike or I’m a bit unsure of...which is the tub roll during the rinse cycle of heavy loads but I do have a feeling that it may be the way it was designed to handle unbalanced loads with the TrueBalance anti vibration motion feature. The engineering experts might be able to shed some light on that. The high speed rinse is a plus and makes easy work for my dryer which I love, also saving on my energy bill. Had this washer for a few months and I like it and I’m satisfied. I keep a absorbing cloth near after every wash to dry out any remaining water that’s left on the door and in the rubber seal area to avoid future issues, and do follow the maintenance recommendations. Good washing machine.

Great Washer
We recently changed our traditional washer to the new front loading and we couldn't be happier! This washer is awesome! The smart-app notifies you once the clothes are washed and ready to move to dryer along with being able to start it remotely as well. Very energy and water efficient, we should have swapped them out a long time ago. We couldn't be happier!!
by KillerMike
Love all the options!
We have had this for about 3 months now and the thing that amazes me the most is all the different settings so just using normal isn't a thing anymore. You can have it wash as long or as short as necessary for the job, which saves time. Very impressed with this. Plus, the notification on my phone and the sounds it makes are the best.
by Donovn1
A Great Choice
We bought this item, not familiar with LG but we are glad we made that choice; a Great product.
by Msdomar
Bought this washer to put in bathroom closet so my wife wouldn’t have to go up and down stairs. I wanted a quiet, reliable machine. This one is perfect. Our old top load washer in the basement sounds like a B52 engine winding up before takeoff.
