Gmom727 9/20/2020

Got ours yesterday. So far we love it. The major issue we do have is that the instructions that come with arent specifically for this unit although it says it is. There arent any instructions that mention the drying function at all. Really would like instructions that are useful and complete.

Doesnt have to be vented.

Bevw 9/11/2020

We have had our LG washer/dryer in one unit for over 15 years. We had to get it in White because that was all that was available at the time. We live in a condo and cannot put a vent in the wall. This was and is our perfect option I am so glad to see they do have it in black now it will now match my other kitchen appliances. Very Very happy. It takes longer to dry but that is OK with me I do not have to leave my apartment and go to a laundry mat or room

I have had two of these

Elarson52 8/28/2020

I love this all in one. I had one and when the ball bearings wore out after 10 or so years I immediately got another. I am one of those that forget to move the wash from the washer to the dryer and had to rewash. This solves that problem. I agree that this takes more time than a washer and separate dryer but it is not a problem for me. I do not have a large family and only do a few loads a week. I love that it can just sit in a closet and I have no dryer duct to clean out and worry about starting on fire.

Love this machine

Golddog 8/28/2020

We have the previous model of this washer/dryer combo and have had it for 3 years. It performs flawlessly. Clothes are cleaned well it does take a while to dry but that is to be expected with a condensing unit. A full load of sheets or towels takes only about 3 hours start to finish and that is perfectly acceptable to us. If one has a large family this may not be the type of unit to get as it does take longer but for the two of us it is just fine. I highly recommend this for those who want to save space save electricity and have clean clothes.

Doesnt actually clean clothing

Alleycattt 8/5/2020

Purchased this combo to save space in our lake home. I cant understand why it wont properly clean our clothing. It leaves our clothing still dirty and smelly Its awful and i cant figure out what were doing wrong. It only seems to some what work when I only wash and then open the washer to only have to set it to the spin and dry cycle which takes forever. Washing pods would not work and only leave our clothes stained and the pod half drained and dried into our clothing ruining it. So I then switched to liquid detergent with not much improvement. Really disappointed we had high expectations but its really become a waste of time and energy. I cant figure out if were doing something wrong. We love that it saves us space but it defeats the purpose of our clothes are still clearly dirty

Incredible Machine

cosmo3405 7/30/2020

I bought the LG all in one the first year it was offered and that machine is still in service in my home. The only thing I have ever had serviced was the drain hose. My experience has been so great I bought another one about 2 years ago for my condominium at the beach. Many people dont understand they are benefitting from super clean clothes the convenience of not having to move a load of clean clothes to a dryer everytime and tremendous savings in water and electricity. Operation has shaved $60 a month off my utility bill. I hear people griping about the drying function. Yes I give my clothes one good shake before I fold them but thats it. I would never go back to two separate units. Thank you LG

Nothing

Denise82 7/22/2020

Purchased Model WM3997H*A a couple of years ago. After 1 1/2 years had to replace a something to do with the drum machine would not spin. Four months later 4/2020 same problem had to replace the same part again. Now 07/2020 again machine will not spin. Worst investment I ever made. Going to purchase a separate washer and dryer and throw this machine to the dumpster. I am so disappointed in this product and do not recommend.

Exceeded my expectations

JAM52MY 7/19/2020

Desperately needed additional space and couldnt use a separate washer dryer. The ventless combo unit was the solution or so I thought it was. Agonized for months on which way to go let alone which manufacture. After reading all the reviews over and over again I settled on the LG it consistently had the best reviews. I can do full loads without removing half for drying as most recommend. The dryer runs longer than a standard dryer but not excessively. Expect some dampness when the drying cycle ends but its minimal.

Just Right When There is Nowhere to Vent

JIGITYJO 6/30/2020

The unit was delivered about a month ago. We chose it because of limited space and nowhere to vent. Unit does exactly as described. Washes and dries. Takes a little longer but very easy to use. We also bought the sidekick unit for quick small loads. Very happy so far. I also really like the sanitary cycle. Takes the stink right out of exercise clothes.

Awesome

GGWILL0 6/28/2020

I just got this to replace 8 year old washer/dryer set. It is awesome Yes it takes round trip for me about 4 hours per load. If you pull items out right after the cycle it is slightly moist but once out in normal air it is dry and fresh. Ive done my bedding clothes towels and dog bedding all without problems and am very satisfied. A lot of people ask about just drying its easy 1. Turn on. 2. Press Dry and select setting. 3. Decide if you need spinning if really wet you will want to leave it on. 4. Press Go. ...... Now i have an extra outlet more space Im using less water less power less detergent and cleaner clothes

Impressive Performance

Cory123 6/20/2020

I have owned this W/D combo for just over a week and I am truly impressed. I previously owned individual washer dryer units and expected some trade offs when going to a combo such as long dry times and items not being fully dry however I have been pleasantly surprised While the dryer does take somewhat longer everything consistently comes out fully dry and with little to no wrinkles. I have found that the WM3998HBA performs best when you fill the drum about way and use a fabric softener to reduce wrinkling. Downy Fabric Conditioner gets great reviews and works well The drum is very large so even when full its quit a bit of clothing. Run time varies depending on what settings you select. The average wash/dry time using the Normal wash time and Turbo Dry has been about 3.5 hours for me. Using Normal as the dry setting bumps this up to 4-4.5 hours depending on the load. My only criticism about this unit is that lint collects on the door gasket. Manual lint removal isnt perfect but running a load of laundry that I plan to air dry washes most of it away. Im hoping to find a better solution for this soon.

Amazing

Alex Fox 6/6/2020

Just got this today. Works like a charm. Love the sleek look. Super quiet. Setting up the wifi and phone connection was easy. Takes a little longer to dry but worth it for only running on 110v instead of 220v and NO VENT HIGHLY Recommended appliance.
