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.

Power Clean Big Loads in Under 30 Minutes*

Five powerful jets with variable sprays surround clothes from multiple angles, so detergent can penetrate deep into fabrics for a complete clean-even for big loads-in under 30 minutes*.

Think you can't do laundry on the go" Think Again.

Expand the limits of your laundry room with the LG SmartThinQ® 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.

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.

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.

ColdWash Technology

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.

Fits in More Places

Get extra capacity without taking up extra space, thanks to a 30" depth that easily fits into smaller spaces or second floor closets.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Looks great and washes well

Submitted by GM234 - 7/23/2019

We bought this a few weeks ago when our17 year old Maytag quit. So many more features on this machine. Looks good and so far is great. The short turbo wash is very good.

Up to three extra rinse option..

Submitted by Rob 1 - 7/20/2019

WM3900 performs great with the inclusion of an extra three rinse option on the regular wash and delicate wash. Regular wash with an extra three rinses only takes 44 minutes including 26 minute turbo wash and six minutes for each extra rinse. Cloths look fluffy with all of the Tide detergent removed. Jeans should be washed with the towel option including an extra two rinses. Its normal for an unbalanced load to cause around 5 seconds of door rattling until the drum builds up speed. There is no light but I dont need one. I use Watts water hammer arrestors with no trial run before installation.

This is a sleek and attractive machine that looks great This washer is amazing I could not be happier with it it is loaded with so many washing settings there is even a steam setting. I love the LG SmartThinq Application it is the app that I didnt know I needed. It lets me start wash remotely tell me how many cycles are left before I should run a Tub clean cycle monitors energy use and if there ever should be a problem it can run a smart diagnosis. The large capacity washer handles large loads easily and theres a tray that has individual spots for soap fabric softener and bleach so you dont have to add it to each load just fill them up when they run out. It takes about 30 minutes to do an average load. Theres a pause button if you want to stop the load and add more to the load.

Washer great WiFi connection horrible

Submitted by Rst202 - 7/14/2019

This washer and companion dryer see m to be great products so far. However the wifi feature was one reason for selecting them. For a company that makes tech products LG has the worst IoT connected app Ive used. The washer will not stay connected and after seeing dozens of complaints from people having the same issue for months no fix or update from LG. Save so. E money and get a lower end product. Disappointing.

Almost Perfect

Submitted by Hatteraskman - 7/9/2019

This new model recently became available at Lowes and we were the first folks in our area to order it during a Memorial Day sales event. It took about 3 weeks to arrive which was half the time that we expected and was delivered up a set of steps and into our laundry room. It was hooked up fairly quickly although it is fairly heavy thanks to a tip from the delivery guys to spray Windex on our tile floor and slide it into place. Make sure that you remove any plugs in the ports on the back of the machine before attempting to hook up your water hoses its obvious if you are looking at the back of the machine but not so if you are leaning over from the front. We ran a test cycle to flush out any contaminants in the internal lines and checked the various controls. The addition of a clean cycle was a welcome addition from our previous LG washer which operated without a problem for nine years until bearing wear turned it into a jet engine 8. Since the installation the machine has performed flawlessly and it is amazingly quiet even more than the previous one with no vibration or shaking even with a full load. It has a heavy duty door more cycle choices and a volume control for the alert system that can be turned off if the kids are taking a nap. The only flaw that we have noticed and its hard to understand that LGs engineers didnt catch it is that the electronic display is hard to read due to a contrast issue. Young sharp eyes may not find that to be a problem but for older people it is an issue and I would have made the rating 4.5 stars if it were possible because of that feature. Otherwise its a great product and hopefully will last as long as our previous model without incident.

I have had this washing machine for a couple of weeks now and I cannot get over how impressed I am with it First of all it is gorgeous to look at Despite there being a ton of options enough for anything you could ever need this machine is very easy to use. Just a couple of quick pushes of the buttons and a turn of the dial and you will be washing your first load. Oh and what a beautiful thing to behold My husband and I were simply mesmerized and sat in front of the machine for the entire first wash I have not yet tried the wifi features but if that is your thing I am sure you will be pleased Besides being incredibly easy to use the machine is also super quite. There is a cute little jingle programmed in to let you know when your load is done and ready to be switched over to the dryer. I was so blown out of the water by this machine that I immediately purchased the matching dryer I dont think I could ever go back to a plain Jane washing machine again.

Submitted by Trojansam - 6/28/2019

This washing machine is the cats pajamas First of the high capacity tub is amazing for large bedding pillows etc or just to catch up on large loads of procrastinated laundry I couldnt even tell you how many options there are but you can customize each cycle for water temp pre treating rinse time soil level and more There is absolutely a setting for every wash youll ever need. And even with its large capacity its relatively quiet and hardly vibrates. Fantastic overall product 10/10

Excellent design and works great

Submitted by souns95112 - 6/27/2019

I absolutely love my new LG washing machine stylish design and looks and works great. It is really very powerful because it has 360 turbo wash technology. When it starts running there is variable sprays surround clothes from multiple angles thats why detergent penetrates deep into fabrics for a complete clean. I am amazed that it even cleaned big loads in under 30 minutes. There is a small LG sidekick pedestal washer or wash two loads at once to save time now I can wash small loads like underwear kids clothes that just cant wait. I am very fascinated about the LG SmartThinQ app. This app is so amazing connects through wi-fi so I can select a cycle expand the limits of your laundry room or stop the wash and I also get notifications about when my laundry will be done i have access to all from my smartphone. I even connected my LG washer with the Amazon Alexa so you can manage it with simple voice commands. I am very happy with the cold and steam wash technology improves the life of my delicate/expensive clothes. I love it so much very impressed with performance I will highly recommend it to others.

Nice features

Submitted by JC Shawnee - 6/27/2019

I have used my new washer and dryer for a couple on months. The features of the washer and the ability to customize each cycle are great. Some items require an extra spin and many washers do not have that feature. The capacity is very nice also it will take king size bedding no problem. It does however require extra one or two rinses and I use regular Tide liquid sparingly.

Love Laundry for the First Time

Submitted by Millse03 - 6/27/2019

This LG front loading washer is state-of-the-art. It was so easy to install and set up to my wifi. It has all of the settings I want and more No more washing my delicates by hand and its big enough to wash my bulky items that I used to have to take to the dry cleaners. I love the sanitize mode for washing my cleaning cloths My favorite feature is being able to start my laundry with my smartphone. I no longer view laundry as a chore it is versitale enough to clean every type of fabric or garment big small delicate or super dirty It is so energy efficient my utility bill is cheaper now

Love The App

Submitted by bv209 - 6/26/2019

I havent had a front load washer in many years. I was a bit intimidated by all that this one has. So different and a bit complex. But with a little time and playing around I am learning all of the setting and uses. First I love the look its a beautiful steel metallic gray thats what I call it. Second the capacity is larger than my previous top loader which means I am able to wash large comforters at home now instead of running those to the local laundromat. With some of the features I am able to freshen comforters that are not dirty but just need a freshening. I use this for blankets that have been on the bed in the guest room that havent been slept on but need a good sanitizing. With the 5 jets cleaning my clothes are cleaner and also I feel I am using a lot less laundry soap. This washer is so much quieter than my previous washer which is why I am loving the LG app. I use it to not only start my loads but get an alert to let me know when my load is complete. I think this is by far my favorite feature. I can change the setting right from my phone and it lets me know when its done with a busy lifestyle this is perfect. I tell everyone about this amazing washer and I enjoy doing my laundry more now.

Lg Front load washer

Submitted by ameliah - 6/20/2019

Omg this washer Its absolutely amazing. Ive had lots of excellent washers before but not like this one. Its a smart washer. It connects to an app on my phone and tells me when my wash is finished. It used to take me more than an hour to do a normal wash. This washer zips right through and within 1/2 hour my wash is done and the clothes are so so clean with very little detergent. It has five powerful jets that surround your clothes and deep cleans them. And its so pretty. A beautiful black steel finish. I show it off like some women show off jewelry. My life is changed forever now with this washer. With 5 children and a new baby its a dream come true for me. The most amazing washer ever. I highly recommend it.

Excellent washer from LG

Submitted by Juney - 6/17/2019

This front-loader is a HUGE improvement our existing front-loader washing machine The LG Direct Drive motor spins the tub quietly and with authority. The pump motor for draining is also noticeably quieter-- the loudest things are now the sloshing of the water and the hiss/whoosh as water is added. One thing that I immediately noticed were the jets of water directed toward the clothes. In our previous washer the clothes took a while to get wet and actually start washing. With the jets of water directed at the clothes as the tub spins washing and rinsing are both faster and more efficient. There are so many functions so you can do any kind of wash: whites towels allergenic heavy duty delicates -- you name it this washer can handle it It even has a tub wash setting for when you want an automatic tub rinse The dark charcoal cabinet has a smooth lustrous finish the center knob has a smooth mirrored finish that you can see yourself in and the trim pieces are tastefully done. From the turning of the knobs to the opening of the door to the smooth rotation of the tub this machine exudes quality. One tiny comment about the display area. The background of the display is jet black with light grey lettering. The contrast is legible but when the machine is on and the bright LEDs light up its a little tough to read the panel. That said I rarely change the settings and the touch buttons work well so its not a big deal. HIGHLY RECOMMEND

Excellent feature set. Easy to use

Submitted by PaulC127 - 5/3/2019

I bought this about two months ago to replace a set of 14 year old KitchenAid/Whirlpool frond loading set. The dry died and was not willing to invest any money in repairing a set that old. The LG set fits perfectly. Uses less water and energy and they are much much quieter. They are also very fast when using the speed functions. I dont normally use cold water to wash but I have tried it with this washer and the clothes get very clean.
