What People Are Saying

Rated 5 out of 5 by from Wonderful machine Bought this and installed a week ago, after trying every combination and 6 hours drying time clothes wetter still wet. Before returning the machine saw on utube the guy adjusted the drain hose lower than where it comes out of the machine, we tried that and clothes come out perfectly dry in one cycle, couldn't be happier with the machine, lg customer service didn't recommend this. Love it now.

Rated 4 out of 5 by from Good as long as you know a few things The machine works great! There is a couple of things you need to know before it will work so well. One is that if you set it up per the instructions manual you will have a great washer, but not a good dryer. This is because of the drain set up. For the dryer to work effectively the drain has to be lower than where the hose comes out of the machine. I would recommend that unless you have a floor drain that you buy the pedestal or build a structure for the nachine to sit upon. The only other thing to know is that when the drying cycle is done and you open the door,n the clothes inside c will appear to be damp.This is because of the way the ventless dryer works. Once you remove the clothes and shake them out, you will find that they are perfectly dry. Hope this helps.

Rated 1 out of 5 by from Poor functionality, clothes smell like rubber, pai What I do not like about this machine: 1. You cannot add dry time if you find you need it when wash / dry is done. 2. Shakes violently even though it's perfectly level. 3. The large tub is worthless because you can only use half of it if you want to dry clothes. 4. You have to clean around the entire circumference and dig in to all the grooves afer every single use. 5. You have to clean water inlet filters - this is a real pain. 6. You have to clean the drain pump filter - this is lame. 7. Some cycle settings don't allow drying at all. 8. Cheap plastic door. 9. Clothes smell like rubber.

Rated 5 out of 5 by from Happy, Happy, Happy! I read many helpful reviews (thank you to all for your time and effort in sharing) before buying this unit and moved forward with some trepidation, but have been thrilled with the WM3997HWA (Large unit). I have used it for several months prior to reviewing. Love it!!! It is a perfect solution for my space challenges..and I can't see ever going back to standard W/D units after experiencing this improved one-step process. No vent required! Freed up much needed space. Granted it is different, but I have no issues with drying.. towels, bath rugs, sheets (large unit seems to address the wrinkling issues people have with the smaller unit), jeans, etc. You do have to experiment with settings, but I have found favorites (such as low heat drying) that work really well for me. The only issue that may need to be considered is that occasionally I've noticed some leakage after I clean the filter and replace the drain plug). I have a brick floor so, it is not worry for me, but may be for someone with wood/etc. It is probably a user error...I haven't called LG to inquire. Greatly modernized and improved system....and cleans extremely well! I'd like to see the price come down and a longer warranty period...but otherwise it is near perfection!

Rated 5 out of 5 by from simplicity, space saving, efficient & quiet In the past I was a major appliance service tech. and by that fact a very discriminating appliance purchaser. After using my new LG I am quite impressed. It's controls are easy to understand and easy to use along with energy and space efficient. I have heard they could take a very long time to dry, but I haven't found that to be the case at all but I didn't overload either. Even if wash/dry times were a bit longer that wouldn't be a problem especially if you put it in perspective. If I go down stairs and throw a load in my old set, it may take 45 plus minutes to wash, then I may go back down in 3-4 hours after I remember, and put them in the dryer for 30-50 minutes, then maybe if I think about it, will take them out in another couple hours or even the next morning, making the conventional laundry pair wash/dry cycle pretty long by comparison .

Rated 5 out of 5 by from Better than I expected! I bought this machine a few weeks ago. I read a lot of reviews, both good and bad, and decided to give it a try.In the past I had to go outside, off my deck and down cement stairs to access my washer and dryer in the basement. I have done that for 30 years in rain, snow and 100+ weather. After the sump pump went out and basement flooded I decided to move the washer and have it connected to the sewer on the other side of the basement. Problem was it would need to be raised up to connect to the sewer line. Once raised, it would be hard to access the top loading washer. So I started shopping front loaders. Well they looked so nice I didn't want it in the basement! I looked around my house and decided I wanted to move the laundry up. Water lines and a drain were a given that I would need. Running a gas line and having a vent for the dryer was a problem as the walls are lathe and plaster and outside is brick. Then I saw this machine! No gas line needed and no vent! It made a lot more sense than a stacked unit because the only area where I could put it is my home office which is roughly 7' X 10'. The machine is nice and quiet. I can be on the computer working right next to it and noise is not an issue. I do set the spin speed on high or extra high for most loads, and the dryer function to more. That seems to do a pretty good job over all.There was one time I threw in a towel with my jeans and that load was the only one that didn't dry as well. All towels on the towel setting come out fine! I did buy a folding drying rack and have used that for heavy items like thermal shirts and in no time at all they are ready to put away! Not an issue! All in all I love this machine! If you are thinking about buying one I would suggest reading a lot of reviews, go online and read the owners manual, and keep in mind the 4" space needed behind the machine for it to "breathe". Also pay attention to the height of the drain in relation to where the hose comes out of the back of the machine. When you turn the dial on the left side of the machine some of the default settings come on automatically, but in most cases those can be changed like water temp, spin speed, soil level and dry selection. Did I say I love this machine?

Rated 5 out of 5 by from Best Model Yet! I've owned these type all-in-one's from LG before but this one is greatly improved. I bought the largest capacity knowing that half a load would dry in a relatively normal time frame... with fabric softener, and extending the dry time 30 min... the clothes come out fantastic and I can't even tell the difference from a conventional dryer; and I live in Florida with more humidity... no issues! Its my most FAVORITE appliance I've ever owned :) ....... I just wish they made designer colors instead of just white.

Rated 3 out of 5 by from Doesn't work I bought this very expensive machine a week ago and it does not dry my clothes. They don't just come out damp as some reviewers state, but wet. I have a drying rack to complete the process which kind of reminds me of the old days! I don't know if there is something I am doing wrong or if there is something wrong with the machine. I am thinking of calling Lowes to return the machine. It costs too much money to not be happy with it! I was so hoping this would work as I really need to have my washer/dryer on second floor, and I am limited in space.The concept is wonderful, but no good if it doesn't do the job.

Can you use detergent "Pods" placed directly in the drum;  or as the manual says only place detergent in the dispenser.

Asked by: jack99
We appreciate your interest in this washing machine. We do not recommend the use of Pods, or packaged detergents. The manufacturer recommends the use of a liquid or powdered High Efficiency (HE) detergent in the appropriate detergent cup in order for the unit to be able to dispense the detergent and other additives at the appropriate time during the wash cycle. It is recommended to only use additives labeled specifically for HE washing machines.
