Great Machine especially if you need to save space
The machine does what its supposed to do and its conveniant to have a washer and dryer 2 in 1. To be able to wash and dry without having to take clothes out is helpful and the dryer will start immediately after it is done washing. The only reason I am giving 4 stars is because the lint catcher and drain hose has to be cleaned out every so often and it is located at the very bottom of the machine making it hard to drain out excess water with the little hose. Overall we are very happy with it!

We are still having issues because our technician needs to tell us the exact plug he wants us to get! He gave us something to download but never told us what we need!

Needs work
Lifters/baffles started disintegrating 2 years in. They’re help in place by screws you can only access by removing and disassembling the drum. Not included in drum warranty. So annoying. I had to break apart remaining bits of lifters by hand, clip the screws off close to the drum, trim the replacement parts so it could slide over the stumps. Just make the part easily replaceable guys. C’mom.

What is the maximum water consumption and discharge rate of this unit (and is it high-efficiency)? My condo allows a max water consumption of 20 gallons, and a discharge rate of not more than 7 gallons per minute.
Hi there! Great question! The LG 4.5 cu. ft. Black Steel All-In-One Washer/Dryer with TurboWash has a Load Sensing system for determining the water levels for individual wash cycles. After loading your clothing items in to the washer and you have selected your chosen options, when the Start/Pause button is pressed to begin the wash cycle, the washer will first measure the load size to determine how much water to use for that cycle with your chosen options and it automatically adjusts the water level for the type and size of wash load for best results and maximum efficiency. Due to the high-efficiency nature of this product, water levels may be much lower than expected. This is normal and cleaning/rinsing performance will not be compromised. The washer has a total weighted per-cycle water consumption of 16 65 gallons. We hope this helps! Thank you! ~Rita

Can adding a pedestal help the unit dry faster? Does it depend on the height of the drain pipe? For example I plan on installing the unit’s drain hose under my kitchen sink, which is lower than a standard laundry drain pipe.
Installing an LG Laundry Pedestal under the LG 4.5 cu.ft. Smart Wi-Fi Enabled All-In-One Washer/Dryer with TurboWash® Technology, Model # WM3998HBA has no impact whatsoever on its drying capability, and the height of the drain hose does not have a direct impact on the drying. The drain must be installed in accordance with any applicable local codes and regulations. The end of the drain hose should be located a minimum of 24" (61 cm) and a maximum of 96" (244 cm) above the bottom of the washer. For best results, you will need to locate the end of the drain hose no higher than 66" (168 cm) above the bottom of the washer. As the drain outlet is raised, beyond 66" (168 cm), the drain function will be increasingly affected. The more water that can be drained from your clothes after a wash cycle, the better your drying results will be. What you need to keep in mind is that the washing capacity for this unit is twice that for the drying capacity so if you wash a full load since both washing and drying are performed in the same tub, you will need to remove half of the load for the drying part, otherwise, the drying will take much longer. You also need to remember that for a combo unit, water is needed in order for it to perform the dry cycle.The cold water is used to condense the moisture in the air and dry your clothes. If water is not supplied to the unit, your clothes will not dry, so you willneedtomake sure that both your hot & coldwater taps are fully opened...^Ivan

Can the door be adjusted for right or left opening?
Hi there, Florida2! Good question! If you are asking if the door of this 4.5 cu.ft. Smart Wi-Fi Enabled All-In-One Washer/Dryer with TurboWash® Technology (WM3998HBA) is reversible, it is not, unfortunately. It only opens to the left. ^Jolly

does it have a wash only option?
Hi, ray147! Thanks for the question! There are five options for using this 4.5 cu.ft. Smart Wi-Fi Enabled All-In-One Washer/Dryer with TurboWash® Technology (WM3998HBA): Steam, Dry, Turbo WashTM, Cold Wash, and Pre-Wash. There are also different types of cycles to choose from: Normal, Heavy Duty, Bedding, Bright Whites, Sanitary, Allergiene, Delicates, Perm. Press, Towels, Sportswear, Speed Wash, and Drain+Spin. ^Jolly

Is there an Energy Guide for the dryer portion of this unit? It appears the Energy Guide available only accounts for the washing portion.
Hi there. Thanks for the question. The 4.5 cu.ft. Smart Wi-Fi Enabled All-In-One Washer/Dryer with TurboWash® Technology (WM3998HBA) only has an Energy Guide for the washer. Please get in touch with us if you have questions for us by sending us a private message on Facebook or Twitter using @LGUSSupport, or call our Customer Service at (800) 243-0000, and it we would be glad to help. ^Jolly

How can you get permanent press to dry without wrinkles? We’ve tried all three dryer settings. The clothes come out so hot they burn my hands and wrinkles are burned into the shirts. Support says this is normal. I don’t believe it.
Hi, There. There's a lot of factors you have to consider in washing your clothes in any washer such as too many items in the washer for the load size selected, Use of an incorrect wash cycle for the type of clothes being washed, On older washer models, an incorrect water level selection for the wash cycle may not provide enough water for the amount of clothes. ^James.

Can this unit be vented? We have the vent space and would like faster drying time.
The LG 4.5 cu.ft. Smart Wi-Fi Enabled All-In-One Washer/Dryer with TurboWash® Technology, Model # WM3998HBA is a ventless unit that uses a ventless condensing to dry your clothes without the need for external venting, and it cannot be vented...^Ivan

what is the max washing load in pounds for the 4.5 cu ft washer/dryer combo.
Regrettably, there is no specified max washing load in pounds for the LG 4.5 cu.ft. Smart Wi-Fi Enabled All-In-One Washer/Dryer with TurboWash® Technology, Model # WM3998HBA. Clothes should be loaded loosely but you should not overfill the drum. Clothes need room to tumble freely in order to get clean. A capacity of 4.5 cubic feet will hold about 20 to 22 pounds, but keep in mind that 20 to 22 lbs. of dry laundry items weigh a lot more when wet so as not to put stress on the washer, 18 lbs. will be a safer load to wash in this washer...^Ivan
