What People Are Saying

Rated 5 out of 5 by from Great machine! Having purchased other LG products of which i have always been very happy with the quality and reliability of the products, I decided on this combo washer dryer and couldn’t be happier with the results. The features and ease of use with the highest satisfaction of the machine are remarkable. I would highly recommend this for others looking for a small machine that does it all with excellent results. Thank you LG.

Rated 5 out of 5 by from This is a perfect gem I received my machine about six weeks ago. It is a perfect fit in my bathroom. I am very pleased with the performance of all the washing & drying cycles, including some of the extra features. This LG appliance has made doing laundry so much easier.

Rated 4 out of 5 by from LG Washer / Dryer Have only used it a couple of times, It is way better than the burned out Asko it replaced. Forgot about the Depth measurement, but was able to configure, with 90 Degree hoses to get it to fit the closet it is in. Unbelievable amount of preset options, dry cycles available. I had mainly bought this unit to fit a limited space, It is sturdy with nice fit/ finishes. I am Hoping many years of use, problem free with it.

Rated 3 out of 5 by from A bit of a problem. The washer/dryer is perfect for our small spaced cottage and so far seems to perform as advertised with one major exception. We have had service out to balance and level the machine (which probably should have been done upon delivery) and in all spin cycles it vibrates to such an extent that literally, the house shakes. We will continue to request service and correction so no five stars until the thing smooths out.

Rated 5 out of 5 by from Very edficient I had the same condenser washer dryer combo that I bought 13 years ago. It wore out and couldn’t be repaired anymore. I’m thrilled with the new one. It seems the technology is greatly improved and it dries better

Rated 4 out of 5 by from LG Combo Washer/Dryer 2.4 cu Due to some bad reviews I was hesitant to buy this machine. But another customer said he bought it for his son and it dryed the clothes just fine. His recommendation combined with the $200 LG rebate convinced me to give it a try. The risk was a success! We love it. For 1 or 2 persons it is great. Not recommended for a family with lots of laundry. We do a load every other day and the clothes are washed very clean, and dry in 2.5 hours. I usually use the timed dry for an hour, towels need 1.5 hours to dry. You can also just wash or just dry. Very flexible and a lot of options. I have gas and a vent for a dryer but all the machines were too big and bulky. This one allowed me to build a counter for folding clothes. When done I will have a cabinet and shelf above and a screen to hide the pipes. I bought an end cap from Ace Hardware on line to close the open vent. The key is to read the instructions because it works differently than what we are generally accustomed to in the US. If your clothes are very wrinkled, you dryed them too long. You should be able to pull out a cotton shirt and see the water evaporate into the air. Practice. For us it is perfect because as we age my purchases are getting smaller and lighter. (But this machine is not light.) The only complaint is the diagnostic app doesn't work with my new android LG Aristo phone. Hence, the 4 stars not 5 stars. Now I will buy the 10 year store warranty and we should be all set for a while. LG stated on their website, if I recall correctly, the parts are free for 5 years but not the labor. I recommend the machine for singles, couples, elderly, and professionals not families. Go for it, you will like it.

Rated 5 out of 5 by from Exactly what we needed! We have a summer retreat using a 12 vdc water system near a small pond. Trips to the laundromat are a 50 mile round trip. We created a space for this washer and are thrilled with the results! We use primarily the wash and dry setting. Commonly it takes 2-3 hours for a load which may seem long but bear in mind the process is hands off from the time you press Start to the time the chime plays signaling finish. The washer uses very little water which is important for our gray water system. It is very quiet and the automatic balance works well to help bulky items from shaking. KUDOS LG!

Rated 3 out of 5 by from i thought it was going to be practical but it isnt It is supposed to save you space , i bought this 2 in one (washer and drier) because i just moved to a very small townhouse but i think i made a mistake. It takes from 4 to even 6 hours to have my clothes washed and dried. I have looke to save time but the less time it takes to dry my clothes is 2 !/2 hours. other than that is a beautiful washer. I did not return it because i already throw the box and used it once if not i would exchange for a conventional duo.

Can you vent the Washer/Dryer Combo units? We just have a small space however can vent. Thank you for the help!

Asked by: Agibson11
The LG 2.3 cu.ft. Compact All-In-One Washer/Dryer, Model # WM3488HS and our other Washer/Dryer Combo units do not vent. They all use a Ventless Condensing Drying System and they do not have a vent duct...^IFV

Hello LG Team, Can this unit (or any others) be connected to a kitchen faucet with a conversion kit? If yes, does this come with a conversion kit? If not, where can I pick one up?

Asked by: Vosq
All the water inlet hoses for this LG 2.3 cu.ft. Compact All-In-One Washer/Dryer, Model # WM3488HS and all our washing machines are 3/4" connectors. The washers do not come with adapters for connecting them to kitchen faucets. There are adapters available from most home improvement stores like the Home Depot, Lowe's etc., that you can purchase...^IFV

Is there a drain hose extension I can buy? If LG does not make it, what diameter size should it be? Thank you.

Asked by: Dave1313
Hi Dave1313. You will need to inquire about extension drain hoses that you can use to extend the drain hose on the LG 2.3 cu.ft. Compact All-In-One Washer/Dryer, Model # WM3488HS from Home Improvement stores like the Home Depot, LOWEs, etc., They usually carry kits that you can buy for this purpose. You may need to install a vent if the washing machine is more than 4 feet from the vent stack to ensure that the washing machine wil drain properly. You also need to be aware of the building codes where you live. All draining has to conform to your building codes. In some areas, you have to install a washing machine drain air vent in order to be legal, but in other areas, you don’t...^IFV

Are you SURE that this model supports a "dry only" option? The larger 4.3 unit has a separate "dry" button and this one does not. Previously asked the answer was Power, Dry, Start. There is no "dry" button on the smaller unit and the manual is no help.

Asked by: Fred Farkle
Hello Fred, per the model number you have supplied, WM3488HS, there is a button named "Dry" between "Spin Speed" and "Pre Wash". If you press the Power Button once, then the "Dry" Button to select the option (toggles between: LOW TEMP, DAMP, NORMAL, MORE or TIMED) and then press Start, the unit will Dry only. Should you need more assistance, do not hesitate to connect with us directly via Twitter @LGUSSupport Facebook or by phone at 1-800-243-0000 ^AC

Is it possible with this unit to run a dry only cycle or do you have to repeat the wash/dry cycle all over again....sometime the clothes are still damp and I would like to RE-run the dryer phase...

Asked by: Dave n
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 see your manual. ^AC

I have model question is am I supposed to set the washer cycles & the dryer at the same time & then push the start button?  I’m doing the wash & when it’s done, then I set the dryer!  I think I’m doing it wrong! Help!

Asked by: Nikkiblu
Hello, if you are wanting to wash and dry at the same time, available on select loads, you would do the following: Press Power > Select Cycle: Example Cotton/Normal > Change or Add options like Soil Level, Water Temp, Spin Speed, Water Plus, Extra Rinse, etc. > Press the Dry Button until you have selected you desired option > Press Start Please refer to the chart on page 23 in your manual as to which cycles you can wash and dry in the same cycle. ^AC

Since the WM3488HS has the built in water heater, does it require both hot and cold supply lines?

Asked by: Stvnewk
Hello, the internal heater is only there to bring the water up to the sanitary cycles and such. The unit must still be connected to hot and cold water inlets. ^AC
