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.


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.


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.


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.


Deep Clean With Steam

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


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.

What People Are Saying

Rated 4 out of 5 by from Great Washer I have the washer for about three weeks and it has been great. The different features it has for example the laundry comes out where it’s slightly damp. By putting this into the dryer the drying time is cut down a lot which is great. I have washed summer weight quilts king size. Saves on dry cleaning. The amount of washing detergent needed is very little to wash clothes. The sales person that I spoke highly recommended this make and model. Overall a happy customer. Cheers.

Rated 5 out of 5 by from Life is Good with my new LG I just love my new LG. I had a older version for years and it was a good washer but had a few issues. This new LG has fixed all those issues and added some great new additions to things that I love about LG. It even plays a catchy little tune when its done, wash is complete and cleaner than ever and life is good.

I just inherited this 2 year old washer yesterday. I heard that it requires a special "low suddsing" soap. Is that true, and if so, what type of soap should be used? I've also heard that you can use any laundry soap, just way less. I use GAIN.

The ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity TurboWash® Washer, Model # WM4370HWA is specially designed to use only HE (High-Efficiency) detergent which is available as liquid, or powdered detergent and as detergent pods. These detergents are identifiable by the HE logo on their packaging and you will need to follow the manufacturer's instructions on their use. If using HE Detergent pods, do not place them in the detergent dispenser. They will need to be put directly into the tub before loading your clothes. ^CP
