Laundry At the Speed of Life

Soccer practice. Groceries. Dinner. Dishes. Shouldn't your laundry move as fast as you? Now it can, with LG's enhanced TurboWash® technology. Powerful high-pressure nozzles save 30 minutes per load, cutting wash time by half—without shortcutting cleaning performance, even on larger loads. Innovation that keeps up with your family calendar? That's not just laundry done fast—it's laundry at the speed of life.

*Compared to an LG top load washer without TurboWash. Based on AHAM-HLW-1-2010 test protocol. Cotton / Normal or comparable cycle at default settings, 8 lb. loads. Excludes quick wash or comparable cycles intended for small, lightly soiled loads only.

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 4 out of 5 by from Happy Washer! I bought this machine a week ago and have used just about every cycle. Our decision to purchase this machine was to increase space in our mixed-use pantry / laundry room. I really like the machine. Two features missing that would move machine from a 4 to 5 star are 1.) add a chime in between wash and dry cycles so that dryer sheet could be added; 2.) add a cool down cycle for dryer to minimize wrinkles. You do have to get used to the time it takes to do a load of wash. I have found it important to remove clothes as soon as you can to minimize wrinkles. The clothes can feel damp when you initially take them out of the dryer. However, when you start folding you realize they are dry. I even washed our queen size bedspread and a queen size quilt. Both washed and dried great! Very happy overall with this machine and would recommend it.

Rated 5 out of 5 by from Wife ha MS Purchased our washer/ dryer combo about 6 years ago after finding out my wife had MS, researched and found this washer / dryer combo so she would not have to pull wet heavy clothes out of the washer. It has performed as advertised with minimum issues or repairs.

Rated 5 out of 5 by from In Lurve We've had this unit for about six weeks. I was skeptical after reading reviews about drying time, but I've not had any problem with it. We generally do smallish loads (family of three) and use the speed wash setting and normal dry for stuff we don't hang. It is good-looking, quiet, easy to use, and the size is perfect. Even my husband, who rarely gets excited about household appliances, raves about this machine everytime he uses it.

Rated 2 out of 5 by from Clothes never get dry I should say the concept of having washer and dryer together is good but practically you never get what you want. Due to the nearly only 50% of capacity compared to a regular dryer, you have to load really very little of clothes if you want to get them really dry when done! It is very very inconvenient for us after using a few month that every time after we take out the cloth, they are still damp. I have to throw them back and dry another 30-60min or so. You can only load half of what MFG has suggest. Never load more. You need to spend 3X more time (2hrs or so) in drying a load compared to a regular dryer load (45min). Think about it before you purchase.

Rated 5 out of 5 by from Love this combo machine.Question on cleaning lint I recently had my washer/dryer combo installed and washed a couple of loads and thought the clothes came out wonderfully dry. Could be that it's new. My question is how do i clean out the lint like I would normally in dryers. I do not see any compartment to removed lint build-up. How does this work??

Rated 5 out of 5 by from saves steps I enjoy putting my clothes in and, when I take them out, they are dry and ready to put away. I have a small space for laundry. With my new combo, I have been able to a add a small folding table, and I gained so much hanging space. I was concerned that the clothes would come out twisted together and very wrinkled. There was no need to worry. This combo does a wonderful job!

Rated 4 out of 5 by from Definately an upgrade. My old washer broke and I bought this set and have been pretty happy with it. Its much quieter and does a better job. Takes a little longer but is worth the wait. It almost has too many features.

Rated 5 out of 5 by from Excellent Product I absolutely love this washer/dryer set! I am so pleased with this purchase, all the settings work excellent and the overall quality/design/look is amazing, fits so wonderfully in our new laundry room. I am actually excited to do laundry now!

You must be joking. It doesn't even include the hoses you need to hook it up.

what is the drying capacity and how long does i take to dry a load

the older models would run for 4+hrs has that inproved with the new 4.3 combo?faster drying ect. thanks
Asked by: abcefd
If you repeat the dry cycle over and over, after a few days the clothes will come out dry. But your living space will smell like wet dog, with moisture on the walls, and if you have allergies like mine your lungs will burn any time you enter the same room as this thing. Enjoy!

Can I use a laundry pod with this machine rather than liquid or powder detergent?

Asked by: GerriW
The LG Front Load Washer / Dryer Combo, Model # WM3997HWA is specially designed to only use HE (High-Efficiency) detergents. HE detergents produce fewer suds, dissolve more efficiently to improve washing and rinsing performance, and help to keep the interior of your washer clean. If the laundry pods you intend to use have the 'HE' identifying logo on them, then they can be used and you should follow the instructions on the use of those laundry pods as indicated on their packaging...^IFV

How do I end drying mode and unlock door

Asked by: Chef winters
Pushing the 'Start/Pause' button on the LG Front Load Washer / Dryer Combo Model # LFXS24623S should stop the machine, but keep in mind that if the temperature inside the unit is too high, the door lock will not unlock until the temperature internally has subsided to safe levels...^IFV

clothes are NOT dry!

We took delivery on a REPLACEMENT unit yesterday. I had a unit for 4 years and am used to it's quirks. THIS unit has it's own. yesterday I did a "mixed" wash and it did not dry. I re-did it on dry only and it still did not dry. I put in 2 beach towels this morning with all hope. I set it at Towels...came home and THEY ARE VERY, VERY DAMP like materials (as opposed to mixed) Normal dry.... We had major, major problems with the former machine not drainng AT ALL and this is the replacement....HELP!
Asked by: LoriP
We apologize for any inconveniences that this has caused you. You may want to check the venting duct that is connected to your LG Front Load Washer / Dryer Combo, Model # WM3997HWA for lint build up. Sometimes the duct will become clogged, caked or full of lint that is constantly being removed from your clothing when drying. When this happens your dryer is unable to expel the hot air from within, therefore making it impossible for your dryer to actually dry your clothing in a timely manner or at all. If it is not clogged up with lint, make sure that it is not kinked because that will also not allow the dryer to expel the hot air properly and your clothes will take forever to dry...^IFV

LG WM3997HWA - What is drying time for a full load, half load

LG WM3997HWA What is drying time for a full load, half load Are the clothes completely dry or do we need to hang up
Asked by: Bob987
You will need to break the full loads down to four separate loads and dry them over a 9 to 10 hour period. Other than that, they will never dry. This machine does not work properly or even close to how it is advertised. The picture of my unit is where it belongs, in the garage, unplugged, next to a garbage can. Too bad it doesn't fit in the can.
