What People Are Saying

Rated 4 out of 5 by from Fantastic for what it is I've had this washer/dryer combo for about 4 months and it's much better than the prior product I had in the space. This is the kind of appliance you get when you don't have the room for a separate washer and dryer, but would like to have a washer and dryer. This is exactly that, and it's probably the best of its kind. The washing portion of this machine is 5 stars. Does everything any other washer would do and more -- its steam cycle and allergiene cycles provide the best clean ever. The dryer is a condensing dryer so it doesn't quite dry 100%, but gets really close -- although takes about 4 hours to get there because it doesn't vent. My only wish to make this a 5 star appliance is for it to have the option condensing or venting, so that it would make the dry cycle faster with an added vent outside.

Rated 3 out of 5 by from Drying Issues We have owned this unit for just 2 years. For the past several months the clothes took longer and longer to dry and sometimes not at all. Luckily we bought the extended warranty through Lowe's and had the repairman come look at it. After replacing what looked like a cracked heating element, which wasn't the issue, it was discovered the unit was allowing dirty, soapy water to come back into the unit during the drying cycle. The repairman zip tied the hose closed that was connected to the drain hose and this solved the problem. Unfortunately there are no Factory Authorized LG Technicians that are allowed come to our little town thus the repairman Lowe's uses for warranty work for our area does not have the access to the data required to service this unit. There may be a check valve connecting to the drain hose that has failed but since the technician doesn't have access he can't tell. LG has been no help finding a Factory Authorized service facility for my area. When calling their help desk and manager numbers I was put on hold for over 30 minutes multiple times. And now I get no returned phone calls. Luckily the tech that came had run into this issue with a different washer/dryer combo. [This review was collected as part of a promotion.]

Rated 2 out of 5 by from I want to like this more! Everything about this is great, HOWEVER, I cannot simply find how to use the DRY ONLY feature. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Good product I have been using the washer/dryer combo and find that it fits my life style. I can put the clothes in and leave. When I come back everything is done. There is no moving the laundry from washer to dryer. This is very convenient. It does take some getting use to the different cycles and the drying time but it is worth taking the time to learn. If the cycle fits the clothes you are washing and drying the clothes come out looking great. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Easy to use and Convenient! I bought this Machine because I have 2 small kids and a full time job didn't have the time to remember to transfer clothing from the washer to a dryer..When I found this machine online I was doubtful, but it works wonders. Its easy to set for each wash. I load it up before I go to bed or to work and return to find nicely washed and dried clothing..(all thats missing is a machine that folds. Hopefully LG comes up with that next!! ) It also gives you the option to wash only or spin only or dry only. Its perfect! And it washes large enough loads like king sized Comforters cleanly. Overall its a good buy and its energy efficient, that by itself makes it worth it!! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from We love our LG Washer Dryer Combo When we downsized into a smaller house as empty-nesters, we wanted to have everything on one floor of our 1,440 square foot ranch. The previous owners had their laundry in the basement. When our appliance dealer introduced the LG WM3997HWA I was at first skeptical,but my wife was convinced that this would be perfect for us. We did our research and, while we were at first concerned about drying, we became suitably impressed with the reviews that were out there and, armed with that encouraging word, we went back to our appliance dealer and purchased it. We had it installed and started to learn how to operate this new piece of appliance technology. It is perfect for our small family and the features make it a terrific and wise investment. We are fully delighted! [This review was collected as part of a promotion.]

Rated 1 out of 5 by from 3 hours to dry I have owned my washer/dryer combo for a little over a year. I thought the convenience of the washer and dryer would compensate for the lack of drying time, but I was wrong. Even when set for the maximum drying time of 2 1/2 hours, I still need at least another hour to get the load dry. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Very Convenient! I live in an apartment so this was a great option for me since I do not have a traditional washer dryer area. I especially love that I can sit in a chair in front of LG combo and put laundry in, set it to wash and dry and I am done. No having to move it to the dryer like traditional washer and dryers. This unit is great for people that are disabled like me. [This review was collected as part of a promotion.]
