Stacked Washer/Dryer Units

Largest Capacity All-In-One Washer/Dryer

Enjoy the convenience of an all-in-one washer/dryer combo without giving up on capacity. The largest capacity (4.3 cu. ft.) means you have the room to get it all done.

Ventless Drying

No access to external venting? No problem. LG's all-in-one washer/dryers use ventless condensing to dry your clothes without the need for external venting.

Fast Forward Your Wash

Give big loads the same great clean while cutting your wash time by up to 30 minutes* with LG's enhanced TurboWash® technology.

Deep Clean With Steam

Our steam technology gently but powerfully penetrates fabrics to virtually eliminate dirt, odors and wrinkles.

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.

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.

Easily Maintain & Keep Fresh

TubClean Cycle is designed for easy, periodic maintenance to keep your washer fresh. The cycle uses water jets and intense heat (up to 149 degrees) to sterilize the tub and help keep your high-performing washer in tip-top condition.

Follow the tips below to make sure your LG product will fit in the space intended.

Drain pump issues

Wanted to really love this and when it works its great. I have just replaced my 4th drain pump in 3 years. The first one went out not even 6 months into owning this machine which was covered by warranty. I follow all care and maintenance outlined in the manual and clean the lower filter where drain pump is located after every load.

Love this!

We bought our set almost 2 years ago and for the most part we really appreciate it. It does take some getting used to and figuring out what works best for your clothes. I see a lot of people who are upset because the clothes are damp when they come out but that dries quickly and usually works best as far as wrinkles. Smoothing the material out removes the majority of them and hanging the clothes for a few minutes works as well. It requires very little detergent and fabric softener is un necessary. If they could just make a drain pump that lasts more than a year this would be a 5 star piece of equipment.

I like it so far, still learning the dryer portion

I really like having the combo washer/dryer in one. ItÕs very quiet, and the large capacity is great! IÕm still learning how to use the dryer as I canÕt seem to get everything to dry the first run. Other than that, IÕm very please with this appliance.

Happy LG Customer since the new LG Direct Drive

LG 4.3-cu ft Ventless Combination Washer and Dryer with Steam CycleMODEL:WM3997HAIÕve been a happy LG customer since the introduction of the LG Direct Drive washers. Over the years we have had several LG washers and dryer sets [due to your coming out with the red sets] that have worked great. My favorite dryer feature is the ÔWrinkle GuardÓ button. Since IÕve been a long time LG fan I was excited when I saw that LG had come out with another innovative product, the LG Washer / Dryer machine. I expected that a corporation that makes heat pumps, seeing the opportunity to incorporate heat pump technology into a laundry dryer machine, would be awesome. Unfortunately, IÕve been very disappointed with this machine. No ÔWrinkle GuardÕ button: Disappointment began when I saw that there wasnÕt a Wrinkle Guard button among the plethora of multitudinous buttons. Theoretically, this machine has Õwrinkle guardÕ if you hold the button down for three secondsÉ, this does not work. The setting will engage but it does not function as a wrinkle guard. The machine tumbles but the interior is so hot that it just irons the wrinkles into the laundry. Even towels come out very wrinkled and they also smell bad, sort of like melted plastic.No lint filter: Where does the lint go? It accumulates on the gasket around the inside of the door. Not a handy thing if you are trying to remove laundry quickly so it wonÕt wrinkle any worse. If you donÕt wipe the gasket off before removing the laundry the lint will attach to the laundry as you are trying to quickly remove it before it wrinkles.Balance: True BalanceÑAnti Vibration System. Although we have adjusted the feet multiple times the machine continues to bang loudly when it starts to spin. The machine is on a cement floor so the floor isnÕt the issue. Sometimes it bounces around so much we wonder if weÕll have to chase it down the street.Noise: There is a very annoying, continuous, high pitch whine the whole time the machine is running.Settings: IÕve tried numerous settings trying to get it to work but so far, no. Towels done on the ÔTowelÕ setting come out smelling bad due to excessive heat as well as wrinkled and damp. Energy Saving: I canÕt understand how this machine could possibly save energy when the cycles take so long to run. Six hours to wash and dry is a long time for a machine to run.This new LG machine is not the time saving innovative machine that I was expecting it to be. I have finally gone to setting the water temp on ÔtapÕ, spin wonÕt go below ÔhighÕ, soil is usually ÔmediumÕ and the dry temp Wow. Temp is a very big problem. Its almost impossible to get to the ÔLOWÕ setting and even if you get the setting to show LOW the laundry still comes out hot. I am now taking the laundry out while its damp and hanging up it to dry. The concept is a good one, unfortunately the implementation is very bad. I hope that when the LG Engineers come up with the new software or hardware that is needed to make this the awesome machine that it could be, that they will provide the update to their customers as a warranty repair.

Just got it. HavenÕt used it yet. CanÕt figure out how to set a small load to wash and dry in one instruction. Manuel not clear.
