Enjoy the convenience of an all-in-one washer/dryer without giving up on capacity. The largest capacity (2.3 cu. ft.) means you have the room to get it all done.

Ventless Drying

No access to external venting? No problem. LG’s all-in-one washer/dryers use ventless condensing to dry your clothes without the need for external venting.

A Smarter Way to Wash

Easily Maintain &
Keep Fresh

TubClean Cycle is designed for easy, periodic maintenance to keep your washer fresh. The cycle uses water jets and intense heat (up to 149 degrees) to sterilize the tub and help keep your high-performing washer in tip-top condition.

Here to help

If you ever experience an issue with your LG washer,  you don’t have to worry. The SmartDiagnosis™ feature helps the service center diagnose problems over the phone, or with a simple app on your smartphone, helping you minimize costly, inconvenient service calls.

Rated 5 out of 5 by from Love, love love! I have had this washer/dryer for about a month now. I love how I can put in a load of wash, and it can wash and dry overnight. One of the added benefits that I realized after pulling out a load of towels, there was NO static cling, at all, and I did not use any fabric softener. The first few times I used the dryer aspect of it, there was an odor, but that is no longer the case. I am so glad I purchased this!!

Rated 4 out of 5 by from Amazing machine! I bought this washer/dryer combo unit almost a year ago for my 5th wheel travel trailer, but I did not use for 6 months until we moved into the 5th wheel. I read multiple reviews about different machines for mobile usage and they were all pretty depressing until I read about this one and I was given hope. It has a larger capacity, I can fit 5 pairs of my husbands heavy work jeans or 6 large towels (very absorbent) set on "Bulky" or a full tub of regular clothes set on wash/dry. The options available on the machine are perfect, you can choose what works best for your usage. The only reason I did not give it a full 5 stars is there is still vibration during spin cycle but I am calling in a service call to see if we can minimize that issue. My husband was able to install it himself within a matter of minutes, the hardest part was lifting into the closet, it weighs about 200 lbs. I will repost once I have the service call to see if the vibration can be corrected. Overall a GREAT machine!

Do you provide Revit models of your products? specifically this one!

Asked by: BenjaminSFCS
Regrettably, we are not aware of the availability of any Revit models for the LG 2.3 cu.ft. Compact All-In-One Washer/Dryer, Model # WM3488HS or for any of our products. Service manuals may have mechanical or cad diagrams of our products and those would be available to LG Authorized Service Centers or LG Authorized Service Technicians. Unfortunately, we do not have access to them...^IFV

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

Good day, From what I read this combo unit uses a Condenser to Dry the clothes. Can you tell me how the condenser works? Do it use cold water to do the condensation ? Any information on how it works would be greatly appreciated.....Thx.

Asked by: Rockazam
The LG 2.3 cu.ft. Compact All-In-One Washer/Dryer, Model # WM3488HS uses Ventless Condensing Drying. Water is needed in order for this unit to perform thge dry function. This is completely different from how a standard dryer would work. With a combo unit, cold water is used to condense the moisture in the air and dry the clothes. If water is not supplied to the unit, the clothes will not dry...^IFV

how much water does this use per load?

Asked by: IanDenchasy
Water consumption varies based on the load sensor, cycle selected and addition option available. It also varies based on the soil level and type of clothing placed in the unit, therefore there is no set amount of water per cycle. ^AC
