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.

*1. Compared to an LG front 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.

A Smarter Way to Wash

6Motion(TM) 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(TM) 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.

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.

ColdWash(TM) Technology

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

Do NOT buy

Do not and I mean do NOT buy this washer/dryer combo I tell everyone I know about how crappy this unit is and everyone says theyve heard that from several people. We bought ours for our condo in Mexico and was told we had a 3 day return guarantee-well that didnt happen. Its takes over 8 hours to do a small load of laundry Buy a side by side and save your money and sanity This unit does not work. We tell all of our guest that stay in our Airbnb to take their laundry to a laundry service. I have a note in unit saying unfortunately this unit is terrible so take all Laundry to a laundry service. I warn anyone thinking of buying this unit not to buy it Taking 7-8 hours to do a load and it to come out not clean and not dry is ridiculous. I told our builder to quit recommending this unit. I think they learned from me to quit recommending this unit

Great Ventless Washer and Dryer

by: CondoVentlessFocus


Submitted: 11-01-2022

After researching the ventless washer and dryer combo we decided to purchase this unit. It is one of the best decisions. 1 Others have complained about drying is bad. It is actually good. We load the unit with 50 - 70 capacity and the clothes are hot. If we are washing heavier clothing we change the setting. We even wash 2 whole king-size sheets and 2 pillowcases and they came out dry. 2 Others have also complained about certain clothing feeling a little damp after drying. We have encountered that once in a while when we change setting to try things out. When that happens those clothes are hot. We would just flick those clothes and they are fine. 3 Others have also complained about drying takes a longer time. Yes it is taking longer and we estimated it takes 30 mins to 1 hour more. We dont consider it an issue because we put the clothes in and the machine washes and dries without us moving the clothes. We dont sit on the washer till it is done or move the clothes from the washer to the dryer immediately. The time saved from moving the clothes from washer to dryer is negated. 4 Others complained about the maintenance on this machine being more. We disagree. For this machine we wipe the lint on the door/glass and empty the water where condensation is kept once a week. For a normal drying machine we still clean the lint trap and wipe lint off the door/glass and keep the dryer vent clean. If someone wants to use this machine without learning how to use it or wants it to perform how a normal dryer works then this machine is not for them. We love this machine.

So far it is great
