Laundry At the Speed of Life

LG's enhanced TurboWash® technology. Powerful high-pressure nozzles save 20 minutes per load, cutting wash time by half—without shortcutting cleaning performance, even on larger loads. That's not just laundry done fast—it's laundry at the speed of life.

More free time

More free time

Towers of towels, piles of sweatshirts, and a mountain of jeans? Go for it. The ultra large capacity (4.3 cu.ft.) tub lets you do more laundry in fewer loads. That’s time saved and sore backs avoided.

Experience Steam Cleaning

There's no clean like a steam clean. Our Steam™ technology gently but powerfully penetrates fabrics to virtually eliminate dirt, odors and wrinkles.

Count on it

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 warranty.

The hottest thing in cold clean

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.

All the right moves

What People Are Saying

Rated 5 out of 5 by from Love love love it Love this new appliance. Everything is just as was posted on Amazon

Rated 4 out of 5 by from Fantastic for what it is I've had this washer/dryer combo for about 4 months and it's much better than the prior product I had in the space. This is the kind of appliance you get when you don't have the room for a separate washer and dryer, but would like to have a washer and dryer. This is exactly that, and it's probably the best of its kind. The washing portion of this machine is 5 stars. Does everything any other washer would do and more -- its steam cycle and allergiene cycles provide the best clean ever. The dryer is a condensing dryer so it doesn't quite dry 100%, but gets really close -- although takes about 4 hours to get there because it doesn't vent. My only wish to make this a 5 star appliance is for it to have the option condensing or venting, so that it would make the dry cycle faster with an added vent outside.

Rated 3 out of 5 by from Drying Issues We have owned this unit for just 2 years. For the past several months the clothes took longer and longer to dry and sometimes not at all. Luckily we bought the extended warranty through Lowe's and had the repairman come look at it. After replacing what looked like a cracked heating element, which wasn't the issue, it was discovered the unit was allowing dirty, soapy water to come back into the unit during the drying cycle. The repairman zip tied the hose closed that was connected to the drain hose and this solved the problem. Unfortunately there are no Factory Authorized LG Technicians that are allowed come to our little town thus the repairman Lowe's uses for warranty work for our area does not have the access to the data required to service this unit. There may be a check valve connecting to the drain hose that has failed but since the technician doesn't have access he can't tell. LG has been no help finding a Factory Authorized service facility for my area. When calling their help desk and manager numbers I was put on hold for over 30 minutes multiple times. And now I get no returned phone calls. Luckily the tech that came had run into this issue with a different washer/dryer combo.

Rated 2 out of 5 by from I want to like this more! Everything about this is great, HOWEVER, I cannot simply find how to use the DRY ONLY feature.

Rated 4 out of 5 by from Good product I have been using the washer/dryer combo and find that it fits my life style. I can put the clothes in and leave. When I come back everything is done. There is no moving the laundry from washer to dryer. This is very convenient. It does take some getting use to the different cycles and the drying time but it is worth taking the time to learn. If the cycle fits the clothes you are washing and drying the clothes come out looking great.

Rated 5 out of 5 by from Easy to use and Convenient! I bought this Machine because I have 2 small kids and a full time job didn't have the time to remember to transfer clothing from the washer to a dryer..When I found this machine online I was doubtful, but it works wonders. Its easy to set for each wash. I load it up before I go to bed or to work and return to find nicely washed and dried clothing..(all thats missing is a machine that folds. Hopefully LG comes up with that next!! ) It also gives you the option to wash only or spin only or dry only. Its perfect! And it washes large enough loads like king sized Comforters cleanly. Overall its a good buy and its energy efficient, that by itself makes it worth it!!

Rated 5 out of 5 by from We love our LG Washer Dryer Combo When we downsized into a smaller house as empty-nesters, we wanted to have everything on one floor of our 1,440 square foot ranch. The previous owners had their laundry in the basement. When our appliance dealer introduced the LG WM3997HWA I was at first skeptical,but my wife was convinced that this would be perfect for us. We did our research and, while we were at first concerned about drying, we became suitably impressed with the reviews that were out there and, armed with that encouraging word, we went back to our appliance dealer and purchased it. We had it installed and started to learn how to operate this new piece of appliance technology. It is perfect for our small family and the features make it a terrific and wise investment. We are fully delighted!

Rated 1 out of 5 by from 3 hours to dry I have owned my washer/dryer combo for a little over a year. I thought the convenience of the washer and dryer would compensate for the lack of drying time, but I was wrong. Even when set for the maximum drying time of 2 1/2 hours, I still need at least another hour to get the load dry.

How do i get the clothes to dry???? When i put the 30 min it goes to automatically 55 and it starts with spin ive done everything little load to dry removed clothes and it still comes oit damp 

Asked by: Elisha lee
Tracehall0911, will this work by moving the drain down closer to the floor if I'm on a slab? My plumbing routes up just above the washer, through a wall then down in another location. Should the water be constantly filling (i can hear it filling and feel movement in the cold water hose - but don't actually see water)? Does the drum spin then stop and load water every 30 seconds during a dry? I called LG support today and the woman I spoke to told me that turning off the water supply 'may' help drying time. Thanks

My NEW washer/dryer leaks a LOT of water shortly after starting the dry portion of the cycle. It drains appropriately at other times during the wash and rinse, but at dry it drains to the floor. What's wrong? Is this something that can be repaired?

Asked by: jgmillar

Can the portability casters be used with the pedestal attached? 

Asked by: Palmtree619
We appreciate your interest in this washing machine and its accessories. It is not recommended to attempt installing “portability casters” onto the washer, or onto the pedestal. Such an installation will result in instability for the washing machine, and will lead to improper spin operations, and possible machine damage.

Can I safety assume this combo unit automatically goes from washing to drying on it's own......or must it be done manually after the wash cycle?

Asked by: Combo Lady
Yes the dry cycle begins automatically after the wash cycle completes (if you want it to). Great feature - I set it with a delayed start before I go to work and I get home just as the dry cycle has complete.

Just hooked this up last week - The right side and the top get EXTREMELY hot during dry cycle - is that normal?

Asked by: RatManDo
We regret the trouble you have experienced with this washing machine. The location described seems to be near where the DRYING/HEATING element is located, along the top of the machine. This may be normal operation. If the machine does not appear to be operating properly, then it may require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at
