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.

What People Are Saying

Rated 5 out of 5 by from Great for small households This washer/dryer is perfect solution for my condo. It didn't require venting or power upgrade. Most items are fully dry, as long as you don't wash a large amount.

Rated 1 out of 5 by from Warm wet clothes machine We stayed in a condo where this was installed. As you can imagine, a family at the beach needs to wash and DRY swimsuits and towels throughout the week. Whether we attempted loads of shirts, swimwear, or mixed items, we NEVER got dry clothes. We tried more dry and 120 minutes. After running a rinse/drain and dry cycle to try to increase the drying results, we have NEVER gotten a single load to dry. Now on the 8th hour of dry time and have warm WET clothes. Seeing the price, I feel bad for the owners who bought this. I also can’t figure out where the lint goes... but it’s not around the seal... that just sliced my finger open

Rated 5 out of 5 by from Awesome cleaning performance After an exhaustive search, researching every imaginable washer/dryer combo on the market, we decided on the WM3488HW for our needs. We needed a replacement unit as a previous combo succumbed to the inevitable recall list. This unit has many useful, and some not so useful, features to choose from; IE: baby wear. We have no children. That being said, the unit performs flawlessly in its washing and drying capabilities. Our clothes come out spotless, fresh, and clean as if new. The dryer is outstanding. I noticed on many reviews complaints about the dryer. Read the instructions. I can wash a full load of clothes then divide that load into 2, maybe 3, loads and dry each within 50 minutes. Our clothes come out ever so slightly damp but by the time I hang or fold the clothes are perfectly dry and wrinkle free. We are still learning all the features having tried about half. We are so impressed with the performance that we highly recommend this unit to those in less than adequate housing space thus requiring a combination unit. I will bring to your attention in reference to the tcl (tub clean), be very careful with the drain hose. In my opinion this is shabby. Unclick the hose, remove the valve, and drain the washer prior to tub clean. However, if you don't return the hose to its exact position, prior to removal, it will leak and flood your kitchen. I learned the hard way. The little door indicates how to remove filter and reinstall it. In regards to the drain line, it only shows removal and reinstallation. A design flaw. This is a minor issue, at best. Overall, we highly recommend this unit.

Is there any reason that this unit could not be installed outside, on a covered porch?

Asked by: bell99
Regrettably, without knowing what the environmental conditions are like in your area, we cannot determine if you are able to install the LG 2.3 cu.ft. Compact All-In-One Washer/Dryer, Model # WM3488HW outside in your porch. It is designed for indoor use where you have access to an appropriate electrical outlet which must be within 60 inches on either side of the unit and to a hot and cold water supply and a drain. We are only able to advise you on installations that are congruent with the instructions provided in the owner's manual and installations that are not covered in the owner's manual are not covered under warranty...^IFV

I ordered this unit & plan to hook it up to the bathtub.  (A platform is being built so that the machine will sit on the tub.)  I know we will need to purchase a converter for the water.  Do you have any other words of advice or direction for me?  Thanks!

Asked by: asuddock
There really isn't that much more that we can advise you on about connecting the LG 2.3 cu.ft. Compact All-In-One Washer/Dryer, Model # WM3488HS to your bathtub than what you have already assessed as being needed for proper installation. Without knowing how you will drain the unit, just keep in mind that the total height of the hose end should not exceed 96 inches from the bottom of the washer and you should consult with your local building inspector since the drain must be installed in accordance with any applicable local codes and regulations...^IFV

What does CD mean on the screen at end of drying cycle? And clothes were still slightly damp, why?

Asked by: Tony 71
A CD display indicates that the combo unit is in cool down mode. This is normal. When the drying cycle is complete the "CD" message displays. The cool down operation periodically tumbles (25 seconds every 5 minutes) the load with no heat to rearrange and fluff the clothing to avoid wrinkles for up to 4 hours The cool down cycle will continue either until a button is pressed to remove the clothes or until 4 hours have passed. If you are in need of any assistance, have additional questions, or would just like to see our helpful tips, check us out on Twitter @LGUSSupport Facebook or you can give us a call at 800-243-0000. ^CP

This is going in my kitchen & will feed into my sink's drain. What is the diameter of your drain hose? I'm swapping out a small dishwasher drain pipe to accommodate the hose - what diameter PVC pipe do you recommend?

Asked by: AdamBit
That is exactly what i did, but my contractor did all the work. Do not have any numbets, but the machine is a perfect fit for the place dishwaher used to be in. Get a contractor and go for it! It will change your life!

Is this unit stackable? Specifically, could I stack a separate ventless LG dryer on top of this unit so as to provide additional drying capacity (and if so which model dryers would be suitable for stacking)?

Large quantities of dog hair and lint get stuck in the rubber tube. Is this normal? Is there a way to prevent this?

Asked by: ellenc
Hello, since this is a washer dryer combo unit, it can be normal. If what you are washing has a large amount of hair, it is recommended you manually remove excess hair and dirt from the items before washing. ^AC
