What People Are Saying

Rated 3 out of 5 by from Pleasantly Surprised! I have had the combination washer dryer for about a month. I read the reviews which were of mixed opinions. It took me a while to learn to operate with the various settings but I love the way it cleans and the convenience of not moving the clothes to dry them. Negatives - it is noisy but not unbearably so. Clothes must be removed immediately to prevent excessive wrinkles. The outer layer of HE soap pods does not always dissolve.

Rated 5 out of 5 by from Smart machine thinks through the whole process. Fuzzy logic works with the direct drive to do an excellent job, wash and dry. Follow the manual for great results. i.e. wash like items together, heavy jeans with heavy jeans... .

Rated 5 out of 5 by from I have never had a combo washer/dryer before so it is all new to me. But I can say that it is a great concept and this LG combo unit seems to be a very nice example. We have had it for a couple of weeks. The features that most appealed to me: 1) Direct drive motor, no transmission. 2) 120 volt standard electricity, no 220 volt needed. 3) No dryer vent! I had my doubts on the ability to dry anything using the 120 volt wall outlet but it proved unfounded as it dries excellent. In fact I think it gets too hot if you choose the higher temperature settings for drying. We found that choosing either damp or low temperature drying works most of the time. Sometimes we need the Normal dry mode for heavier items. They have a high heat choice but I will not even try that one. This model is the smallest one and is good for 1 or 2 people. If you do a lot of loads or like to stuff your washer to the gills then get the next size up LG combo. If you stuff the washer you may have to remove some of the items to get good drying action. Combo units can wash a larger load than they can dry so keep your loads reasonable and you can just let the combo unit go from wash to dry itself. You can choose a dry only cycle now so the clothes that are removed can be dried later if needed. Apparently they used to supply a blue detergent cup insert for the drawer for liquid detergent. Ours did not have that insert and it seems that they no longer use it. We also found that some detergent pods may not dissolve completely and the leftover plastic film covers up the rubber gasket drain port. So we do not use pods to be on the safe side, just powder or liquid. The washer was put through an empty cycle after installation, but the first load of clothes did have a strange smell to them. It was from the dry cycle. After the first load the smell went away and now there are no odors.

Rated 5 out of 5 by from perfect for big city apartments If you life in a big city like New York, this is the machine for you. Space is often at a premium, and this machine will help you not having to bring your laundry to the dry cleaners or the laundromat.

Rated 5 out of 5 by from Tiny house, dream come true Does a great job on my dirty construction clothes and it's a real solution for a tiny space... it's only about as big as a dishwasher. The fact that it's 120v and ventless makes installation a breeze too.

Rated 5 out of 5 by from Love it! I bought this washer/drier about a month ago. I LOVE IT. It does only a small load at a time but is perfect for one or two people.

Rated 5 out of 5 by from All in one! After years of schlepping basketfuls of laundry to the laundromat twice a month it was an exciting day when my LG combo washer and dryer was finally delivered. I had received negative opinions about combination units when I asked a salesman, but the many positive reviews online convinced me otherwise. As a single person with very limited space this machine seemed perfect for my needs. I took extra care to read the manual and to heed the advice given in the reviews to minimize any potential problems. My very first use had me convinced. My clothes came out of the machine warm and dry and ready to be folded. Yes, the dryer capacity is only half the washer capacity, so do not cram the machine full. And yes, there will be a smell the first couple times you use the machine, but for me at least it quickly dissipated. After having become accustomed to mountains of dirty clothes piled high in my bedroom, it is a welcome change to never having a full hamper. Using the machine couldn't be easier. It easily handles about 3 days worth of clothing. True, it takes a little longer than a separate washer and vented dryer, but I hardly notice the extra time, especially since I can now do laundry whenever I want. It you understand how the machine works and follow the recommendations given in the manual and other reviews; and if you are considerate of the types of clothes you are washing and think about the correct settings - such as adding an extra spin cycle or increasing the drying time - you will be completely satisfied. This machine really is a marvel.

How hot does the dryer get on this unit. And can I get dry heat instead of steam heat.

Asked by: BS60
Electronic sensors in the LG 2.3 cu.ft. Compact All-In-One Washer/Dryer, Model # WM3488HW measure the temperature of the exhaust to increase or decrease the drying temperature for faster reaction time and tighter temperature control when using the Automatic Dry function and the drying time will vary according to the type of fabric, size of the load, and the selected dryness level affect drying time. This unit does not have any Steam functions on it for drying, it uses a Ventless Condensing Drying system. Cold water is used to condense the moisture in the air. If water is not supplied to the unit, the clothes will not dry...^IFV

I cannot find the lint trap? Does this washer/dryer combo not have one? 

Asked by: MaintenanceBR
It does not, as the lint flushes out through the drain line since it uses a condensing system and not a heating element. ^AC

Can you stack Dryer model: DLEC888W on top of this combo unit? Would you need a stacking kit? I like the ease of the all in one combo, but sometimes I like to have the extra drying capacity when doing multiple loads.

Asked by: Jay76
This dryer is a compact dryer that is specifically designed to stack to the W1388 compact washer. It utilizes a different stacking kit that is not compatible with the WM3488. This compact pair will only stack together with a special stacking kit that cannot be used with any other models.

Just purchased this washer/dryer combo and I noticed there is no compartment for bleach. Am I able to add bleach to the wash cycle? — I also wanted to know if we are able to add dryer sheets during the drying cycle?

Asked by: Min14
Liquid or powdered color-safe bleach may be added to the main wash compartment with detergent of the same type. ^CP
