What People Are Saying

Rated 5 out of 5 by from Exceptionally quiet and efficient. The washer and the "Sidekick" were installed yesterday. I've already done 4 loads and I totally love it! It is amazingly quiet and cleans very well - even got out tough stains on a table cloth. My khaki slacks came out great in the "Sidekick." Easy to program and I absolutely love the "time-left" indicator.

Rated 5 out of 5 by from Great Product LOVE this machine. Replaced an older washer and dryer with this and am so happy I did. Besides having more space in my utility room, I don't have to worry about my wet clothes getting left in the washer. Now I just set it and go. I seen on another review that it was stated it wouldnt go directly to dry... thats not true. you just have to press the dry button before you press the start button. Definetly read the manual, this will allow you to understand the features and have a positive experience when using the machine.

Rated 5 out of 5 by from Works like a charm, so easy to install I bought this all in one washer and dryer unit for a lakeside cottage that had a wash tub and hot and cold water hook ups but no 220 service or exhaust vent. LG Unit has performed as advertised as long as you follow the instructions. Have done several loads of clothes and bedding and it has washed and dried perfectly. May take about an hour longer than traditional side by side unit but the ability to install this without hiring a plumber a d electrician was a huge help. Look forward to many years of use.

Rated 5 out of 5 by from It's so quiet! We bought this about 2 months ago and I love it. If you follow the manufacturer's instructions it works great. I can start the laundry before bed or before work and when wake up or when I get home the laundry is ready for folding. It's so quiet and efficient, works great for us. I do wish we would have purchased the pedistol portion as well.

Rated 5 out of 5 by from A 21st century appliance! I love this w/d combo. It has multiple wash settings to meet every need. I've had it for about a month and it cleans my laundry very well. Drying is better than I expected, and I have no complaints. I knew from using similar units in Europe that drying takes longer than a vented machine, but for small loads it's really not much longer than a conventional dryer. Loads with items of dissimilar weight don't dry evenly on the pre-set settings, but I simply switch to the timed setting. As others have mentioned, the dried clothes, upon first removing them, have a different feel, and seem damp for a moment when in fact they are dry. The machine is very quiet, well-designed, and it has more than enough capacity.

I have had this machine for 2 months and love it, except the light has officially gone out and it looks like it may be wet inside.

I know that there is no lint trap... but the door and rubber lining get covered in lint... and it is very difficult to clean as it sticks to the rubber. How do you suggest we keep it clean?

Asked by: Dnm1
We can only recommend you clean the unit as per the manual. The unit needs to have the Tub Clean ran regularly, clean out the drain pump filter and the rubber door seal with a sponge or a soft cloth. Please see your manual under the MAINTENANCE section for all the information. ^AC

Can i use the dryer option without do the wash to dry setting?

Asked by: BMO1
To run just a dry cycle, press Power > Dry> Start. For the most even drying, make sure all articles in the clothes load are similar in material and thickness. Do not overload the washer by placing too many articles into the drum. Items must be able to tumble freely. If you open the door and remove the load before the washer has finished the DRY cycle, remember to press the START/ PAUSE button. The capacity of the machine for washing clothes is twice as much as when drying clothes. If the machine is to be used to dry a load, then the wash load must be reduced by half for effective drying performance. If a full load is washed, remove half the clothes prior to starting the dry cycle. For more information, please feel free to contact us at 1-800-243-0000. ^AC

Where is the lint trap in the combo washer dryer?

Asked by: Chkiii
The Washer/Dryer Combo units do not have a lint trap as the lint flushes out through the drain line since it uses a condensing system and not a heating element. ^AC

How do I get dryer setting to high it's taking forever to dry one load

Asked by: Calles1994
Hello, the unit washes and then dries the clothing in the same drum. Since the unit is a Ventless Condensing system, it does not heat your clothing like a normal dryer. Because of this, it takes longer and is more efficient, also it can take longer depending on how full the drum is. ^AC

Can you use pods? A friend recommended fabric softner pods....my sister told me she uses all in one pod (detergent, bleach,& fabric softner)

Asked by: CAT1923
Yes you can, but if using pods, do not exceed 1 pod per load. Place the pod directly in the drum. Pods may contain too much detergent for small loads. So you may still need to use regular detergent in some cases. ^AC

Can I use Tide pod type detergent in this machine? Does it go in dispenser or straight in machine?

Asked by: Cmerrit123
The LG 4.3 cu. ft. Ultra Large Capacity Front Load Washer / Dryer Combo, Model # WM3997HWA is specially designed to use only HE (High-Efficiency) detergent so check to make sure that the Tide Pods that you intend to use are HE detergent. The HE logo will be on their packaging. You would have to add the pods directly into the tub before loading your laundry. It is recommended that you follow the manufacturer's instructions printed on ther packaging. Do not place them in the detergent dispenser...^IFV
