Description
Features
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.
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 (LG SideKick sold separately).
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.

Does a beautiful job
|Posted .Features
Quality5 out of 5Value5 out of 5Ease of Use5 out of 5Have had this washer for 6 weeks - using it several times a week - and am still very happy with it. My only concern has to do with its installation. As BB installers were leaving, they gave me some sort of legs/pegs and said I could use those to balance it... the top loader we replaced had off-balance problems and I'd assumed this was installed to prevent that. I'm a small, 70 yr old woman so I won't be hoisting it up to put something under it. Wonder is it supposed to have these under it? Photo attached of all the leftovers after installation - red circle around the legs to use to level (?).

Best for the price across the board!
|Posted .Owned for 3 weeks when reviewed.Features
Quality4 out of 5Value5 out of 5Ease of Use5 out of 5Washes clothes much better than my previous top loader with less water. I don’t think the upgraded turbo model would be any different from my current needs judging by the price difference. The menu screen is not as illuminated but my laundry room is well lt. I particularly like the Wi-Fi compatibility as it is very convenient to access the features through the smart phone app. Contrary to what the instructions say, the Wi-Fi CAN log in to the 5G home router’s network. It just takes a little more ingenuity paring it during setup. I’m glad I made the right pick after doing an on line and Consumer Reports research.

2 month use review.
|Posted .Owned for 1 month when reviewed.Features
Quality3 out of 5Value3 out of 5Ease of Use4 out of 5Installation went smoothly with the exception of me needing to move the catch pan location 9" to the right and relocate the drain hole so the washer door would open fully. You will be required to buy a new set of braided water hoses ($29.99) if Best Buy does the installation. As already known, it takes much longer to wash a load of clothes vs a top load. The clothes are as clean as the top load was. Nothing better or worse. The LG design wizards missed the boat on the location of the washer filter/drain tube (door) location. Per building code, washers are to be placed inside a catch pan with drain. The lip on the catch pan blocks the filter door from opening. Should have left off 2/3 of the useless settings and spent another couple bucks on moving this door up 5". I intend on removing the door entirely so I can remove/clean the filter per the manual. We will never use the majority of the vast array of settings or the wi-fi. When it stops washing, its done. I don't need washer info sent to my phone.... some millennial in need of constant attention thought that was a good idea? It's an over priced washer that appears to use less water and gets our clothes clean in about twice the time as our previous top load. *Make sure you have provisions to leave the washer door partially open all the time in between uses or mold will form.

So far so good
|Posted .Owned for 3 weeks when reviewed.Features
Quality5 out of 5Value5 out of 5Ease of Use5 out of 5So the machine itself it’s beautiful, the size is perfect for even nice size comforters to be washed... the one thing that i don’t like, and that’s why the 4 stars, it’s that is a bit noisy, much louder than the one we had before, but other than that, it’s been perfect overall, the setting are very easy to maneuver.

Touchscreen panel difficult to read
|Posted .Owned for 3 weeks when reviewed.Features
Quality5 out of 5Value5 out of 5Ease of Use2 out of 5This is my 3rd LG washer. Same model and features. The only change this time was changing the dedicated buttons for wash options to a touch screen. The touchscreen appears to be designed to be backlit, as the options are etched in the glass. For whatever reason, they decided not to light the button selections or the text for the selected options. It is really hard to see light grey etched lettering on a black background. When I saw the model in the store, I assumed there would be some sort of lighting, but there isn't. I hate to complain, but this is stupid. The photos don't do it justice as the photos enhanced and brightened the options.

Love my new LG FL washer & dryer!
Posted .Had to replace 12 year old LG FL washer & dryer. I was hesitant to buy the same ones but all the other brands are too deep for my space. The Best Buy sales manager told me they have made big improvements since my old model (WM2077CW) and he was right! These are awesome!!! {WM3700HWA & Dyer DLEX3700W} My clothes are so clean & the machines are super quiet! I thought the WiFi option was completely unnecessary but it’s actually helping me stay on top of things by reminding me to “please unload the laundry”. The steam clean option is wonderful and I’ve cleaned all our towels and sheets (it does take longer so I probably won’t do this every time but hoping it will help with kids allergies) & the brightest white with steam setting got all the mud stains out of daughters white jeans. The speed wash is only 15 minutes and worked well for a small load! The steam option on the dryer worked great to refresh dance costumes without having to wash them, they came out smelling great after just 10 minutes. I asked for advice on how to keep away the mold this time and it was recommended to use powered detergent only and hot/warm water as much as possible. Gain original powder is working well and smells great. Also there is a tub clean cycle which my older one didn’t have, and the door will stay open where you place it (the old one was either wide open or closed which is a NO for a FL). I almost forgot; the display panel is easy for me to read & I don’t agree with the negative reviews on that. Happy washing! I love my new machines!

Q: QuestionI just got this machine installed today and it’s loud! Is this normal? It sounds like a broken washer, awful. I put it on high in the spin cycle and I had to turn it off, started shaking even moved out its place. Is this normal or did I get a lemon?
Asked by Concernedbuyer.
- A:Answer Thats not normal, if its pretty loud and shaky then I believe the installation guy has forgot to remove the big bolts on the back of the washer which are supposed to be removed.

Q: QuestionWill this 4.5 handle king size comforters? Will it balance itself in the spin?
Asked by Sonnie.
- A:Answer Generally speaking, 4 cubic feet is enough to wash 12-16 pounds of laundry. A larger capacity unit at 4.5 cubic feet can hold up to 20 pounds of laundry. A general rule of thumb is a queen size comforter can fit into 3.5 cubic feet and a king size comforter fit into a 3.8 cubic feet machine. ^CP
