What People Are Saying

Rated 4 out of 5 by from great features with one problem I bought this all-in-one washer and electric ventless dryer machine 3 months ago, washer good but the dryer only dry at the first time, then never dry and made the machine and the room hot, then I searched the you tube, lucky found a guy had solution, this guy spent 2 years to figure it out the reason and solution: reason: drain hole position is higher than the machine, when the dryer is working, every movement will have little water come out, but did not have enough strength to drain out through the drain hose to the high position drain hole, then the water stuck in the machine and cannot dry the clothes. The drain hole should be on or near the ground/floor. Solution: I follow this guy's idea, put a bucket on the floor then move/put the drain hose in it when I use the dryer then the dryer can do the job. other than this problem, this is a wonderful machine, fit in the small laundry closet, save some money in the electric bill, no more cleaning fee of dryer vent (it is Ventless) and my daughter's allergy symptoms almost gone, finally, we found the reason of her allergy, it is LINT. Please solve the problem of the drain hole in the high position which cannot drain the water when the dryer is working - in the future model, so I do not need to watch the bucket and empty it when it is full, thanks.

Rated 2 out of 5 by from Anybody wanna buy it, CHEAP? A month ago my husband bought a new heat pump water heater. Unfortunately it didn't leave enough room in our utility room for my large capacity full sized front load machines(4 years old) so we bought this machine. I tried. I really really tried to adjust to using it. A week ago I stopped trying to deal with this terrible piece of machinery. I have since made painstaking arrangements to stack my full sized machines on top of a custom made platform to overcome the lack of space to fit my old machines. This machine leaves my clothes covered in lint even though we followed the directions for purging the lint several times. I also have to use a wet paper towel to wipe the rubber seal after every wash to remove pet hair. It did a terrible job of washing my king sized comforter that my old machines handle with ease. It is terribly inefficient when it comes to how long it takes to run a full wash/dry cycle. Often hours for a single load. It also gets very very hot on top during a cycle. It makes me nervous. This machine was a complete waste of money. My daughter is in the process of moving into her first apartment and she refused to accept this machine as a gift.

Rated 1 out of 5 by from Bad combination This machine turned out to be a washer only for which a paid dearly to have both. This machine will never dry your clothes. There is no heating element in this machine. Don't waste your money, it won't dry your clothes

Rated 4 out of 5 by from Happy Washer! I bought this machine a week ago and have used just about every cycle. Our decision to purchase this machine was to increase space in our mixed-use pantry / laundry room. I really like the machine. Two features missing that would move machine from a 4 to 5 star are 1.) add a chime in between wash and dry cycles so that dryer sheet could be added; 2.) add a cool down cycle for dryer to minimize wrinkles. You do have to get used to the time it takes to do a load of wash. I have found it important to remove clothes as soon as you can to minimize wrinkles. The clothes can feel damp when you initially take them out of the dryer. However, when you start folding you realize they are dry. I even washed our queen size bedspread and a queen size quilt. Both washed and dried great! Very happy overall with this machine and would recommend it.

Rated 5 out of 5 by from Wife ha MS Purchased our washer/ dryer combo about 6 years ago after finding out my wife had MS, researched and found this washer / dryer combo so she would not have to pull wet heavy clothes out of the washer. It has performed as advertised with minimum issues or repairs.

Rated 5 out of 5 by from In Lurve We've had this unit for about six weeks. I was skeptical after reading reviews about drying time, but I've not had any problem with it. We generally do smallish loads (family of three) and use the speed wash setting and normal dry for stuff we don't hang. It is good-looking, quiet, easy to use, and the size is perfect. Even my husband, who rarely gets excited about household appliances, raves about this machine everytime he uses it.

Rated 2 out of 5 by from Clothes never get dry I should say the concept of having washer and dryer together is good but practically you never get what you want. Due to the nearly only 50% of capacity compared to a regular dryer, you have to load really very little of clothes if you want to get them really dry when done! It is very very inconvenient for us after using a few month that every time after we take out the cloth, they are still damp. I have to throw them back and dry another 30-60min or so. You can only load half of what MFG has suggest. Never load more. You need to spend 3X more time (2hrs or so) in drying a load compared to a regular dryer load (45min). Think about it before you purchase.

Rated 5 out of 5 by from Love this combo machine.Question on cleaning lint I recently had my washer/dryer combo installed and washed a couple of loads and thought the clothes came out wonderfully dry. Could be that it's new. My question is how do i clean out the lint like I would normally in dryers. I do not see any compartment to removed lint build-up. How does this work??

clothes are NOT dry!

We took delivery on a REPLACEMENT unit yesterday. I had a unit for 4 years and am used to it's quirks. THIS unit has it's own. yesterday I did a "mixed" wash and it did not dry. I re-did it on dry only and it still did not dry. I put in 2 beach towels this morning with all hope. I set it at Towels...came home and THEY ARE VERY, VERY DAMP like materials (as opposed to mixed) Normal dry.... We had major, major problems with the former machine not drainng AT ALL and this is the replacement....HELP!

what is the drying capacity and how long does i take to dry a load

the older models would run for 4+hrs has that inproved with the new 4.3 combo?faster drying ect. thanks
Asked by: abcefd
If you repeat the dry cycle over and over, after a few days the clothes will come out dry. But your living space will smell like wet dog, with moisture on the walls, and if you have allergies like mine your lungs will burn any time you enter the same room as this thing. Enjoy!

Can I use a laundry pod with this machine rather than liquid or powder detergent?

Asked by: GerriW
The LG Front Load Washer / Dryer Combo, Model # WM3997HWA is specially designed to only use HE (High-Efficiency) detergents. HE detergents produce fewer suds, dissolve more efficiently to improve washing and rinsing performance, and help to keep the interior of your washer clean. If the laundry pods you intend to use have the 'HE' identifying logo on them, then they can be used and you should follow the instructions on the use of those laundry pods as indicated on their packaging...^IFV

How do I end drying mode and unlock door

Asked by: Chef winters
Pushing the 'Start/Pause' button on the LG Front Load Washer / Dryer Combo Model # LFXS24623S should stop the machine, but keep in mind that if the temperature inside the unit is too high, the door lock will not unlock until the temperature internally has subsided to safe levels...^IFV

I want to turn off the melody when I run the washer at night.
