Appliances you can count on

LG front load washers have been rated by Consumer Reports.

A Smarter Way to Wash

6Motion™ Technology uses up to 6 different wash motions to provide a smart cleaning experience that is gentle on clothes and maximizes washing performance.

AAFA Certified LG Washers

LG washers with the Allergiene™ Cycle use the power of steam to remove over 95% of pet dander and dust mites.

Think you can't do laundry on the go? Think Again.

Expand the limits of your laundry room with the LG ThinQ® app. Select a cycle, start or stop the wash and get notifications about when your laundry will be done, all from your smartphone. It even works with the Google Assistant and Amazon Alexa, so you can manage your laundry with simple voice commands.

Get it All Done In Less Time

Ultra-large capacity (4.5 cu.ft.) means you have the room to do more laundry in fewer loads.

ColdWash™ Technology

Using the cold cycle on your washer doesn't have to mean compromising. ColdWash™ technology uses cold water and enhanced washing motions to penetrate deep into fabrics, giving you cold water savings with warm water performance.

For Small Loads that Can't Wait

Whether it's your kids' favorite shirt, yoga pants or a school uniform, washing a full load seems wasteful for just a few pieces. Now you can wash small loads that just can't wait with the LG SideKick™ Pedestal Washer or wash two loads at once to save time.

Fits in More Places

Get extra capacity without taking up extra space, thanks to a 30" depth that easily fits into smaller spaces or second floor closets.

Power Clean Big Loads in Under 30 Minutes*

Five powerful jets with variable sprays surround clothes from multiple angles, so detergent can penetrate deep into fabrics for a complete clean-even for big loads-in under 30 minutes*.

Disappointed w/LG washing machine WM3700HWA

clear No, I would not recommend this to a friend

I have an older model LG washer that I am thrilled with.....it sings to me when the wash is done. This newer model does not and that is a disappointment. Wash day is not as cheery.BUT the big disappointment is that I can not see the control panel because the words are not backlit. I need a bright light and my reading glasses because all that can be seen is dashes.

Best Washer I Ever Owned!

done Yes, I would recommend this to a friend

So far, so good after a couple months. No start-up issues what so ever. Easy to use. The operating instructions are pretty good and worth reading. The quality seems great and hopefully that turns out to be true. The only significant drawback I have found is that I cannot customize the default settings or store even one customized cycle setting. Hopefully, LG fixes this or at least patches the Smart ThinQ App. Still gets 5 stars from me.

Quality Has Gone Downhill

clear No, I would not recommend this to a friend

Purchased this unit, along with the matching dryer. Washer drum shakes violently during the spin cycle when washing jeans, towels or anything other than light loads. Maybe the unit wasn't balanced? I checked it with a level and it was fine. Its supposed to have auto balance technology, but it doesn't work. Also, the run time on the normal cycle is never the same (it varies from 29 minutes to 50 minutes) and the clothes don't come clean. Matching dryer has a light that doesn't come on until you manually push the power button and it needs to run a couple of cycles before the clothes are dried. LG used to make a quality product. Not anymore.

Dealing with second failure in 5 months

clear No, I would not recommend this to a friend

I bought this in January and it leaked the second day, it took over a week to get a replacement sorted out. I now have an awful banging sound when there is anything in the machine, I'm talking a few pieces of clothing. LG customer service has not taken ownership of the issue.One week ago I called to report the problem, so they could have a technician out to deal with it, I have had no contact.I called them after 6 days to get an update was on the phone for over 5 hours, had an actual supervisor hang up on me when I pointed out that she was mistaken on the dates she was quoting I called in. No one could give me information on when a servicer would be out, or if someone had been contacted to come out. you have to wait one more day for an escalation and call back to see if its escalated and even then we won't know how long it will beAt this point, I have zero faith in LG as a company or their products. I also think they need to take a look at the customer service they provide and empower their staff with more access to systems and give them more options to take ownership of a customer issue, as i get the feeling LG customers do not feel valued.
