What people are saying

Rated 5 out of 5 by from Strong silent type In 3 weeks I’ve been amazed a dozen times by this amazing machine. It was time to replace our old washer dryer and we shopped around and finally settled on this LG washer /dryer combo . It was a bit more expensive than the others and I was apprehensive at first but it had all the bells and whistles we were looking for and a couple we didn’t know existed. The second we unwrapped it and saw the dark finish , we were in love and we installed it ourselves in a few minutes. It looks intimidating at first but the instructions were simple to follow and we were using it in a couple of minutes . The instruction booklet makes it a breeze with easy to follow diagrams . Once it was washing we all stopped to watch it because it’s almost silent and barely vibrates -even in the spin cycle. The kids learned to use it immediately and have the app on their phones - so they receive notifications when the wash is done . Like I said , it cost more than I intended to spend but after using it for 3 weeks, I’m wondering how they can sell this hard working and efficient machine - so inexpensively. I’d recommend it to anyone who can appreciate a well made , efficient machine . And even if you’re looking to spend less , with this type of quality - you get much more .

Rated 1 out of 5 by from product + marketing The worst product in the market, their product advertisement is misleading I already had two consecutive issues with the dryer and the washer where there was a door leak.

Rated 5 out of 5 by from Love this washer/dryer We bought this to go into a small space and did not have venting, so this seemed a perfect fit and I loved the idea of not having to move wet clothes from the washer to the dryer. It is very convenient but does take some getting used to. Smaller loads are key and you need to plan on roughly 3 hours per load. But it is very easy to throw in a load every other day or so. The app lets you track when your load will be done and sends a notification when it is. The clothes are steam dried and sometimes they feel a tiny bit damp but it is the steam. Once you take them out they are fully dry. Since there is no venting and no lint trap you must wipe out the rubber seal after each use. My one complaint is the drying feature. It is limited if you just want to dry alone and not run a wash cycle.

Hi! Mine sounds very loud when it runs - like a scratching, scraping sound while the drum spins. Is that normal?

Asked by: kateh
The scratching, scraping sound that you are describing while the drum for the LG 4.5 cu.ft. Smart Wi-Fi Enabled All-In-One Washer/Dryer with TurboWash® Technology, Model # WM3998HBA spins is not normal. When you say that it is very loud when it runs and makes those sounds, is that during the wash cycles or during the drying cycles, or for both? Has this been an issue since you unpacked the unit and started using it? Do you know if the shipping bolts on the back of the unit were removed using the included wrench? Failure to remove the shipping bolts and retainers can cause severe vibration and noise which can lead to permanent damage to the washer...^Ivan

what is the best setting for the fastest dry?

Asked by: BergsC
That depends on the size and type of your load. The LG 4.5 cu.ft. Smart Wi-Fi Enabled All-In-One Washer/Dryer with TurboWash® Technology, Model # WM3998HW has automatic dry programs that should be used to dry most loads. Electronic sensors measure the temperature of the exhaust to increase or decrease the drying temperatures for faster reaction time and tighter temperature control. For most drying, make sure that all the clothes are similar in material and thickness, and avoid overloading the drum. Items must be able to tumble freely. The estimated drying time varies from the actual drying time during the automatic drying cycles. The type of fabric, size of your load, and the dryness selected affect the drying time. You can also use the TIME function to select drying times of 30/60/90/120/150/180/210minutes...^Ivan

Assuming this unit doesn't run flush with the wall due to hose/attachments, etc. in the rear of the unit. Approximately how many inches does the unit stick out from the wall?

Asked by: BC123
An installation clearance of 4" (10 cm) is recommended behind the LG 4.5 cu.ft. Smart Wi-Fi Enabled All-In-One Washer/Dryer with TurboWash® Technology, Model # WM3998HBA to ensure sufficient clearance for water hoses, drain, and a natural airflow around the washer. The washer has a depth of 30 1/4" so if you add the 4"installation clearance behind the washer the result will be how far from the wall the front of the washer is. The washer has a depth of 55" with the door open and again, adding the 4" installation clearance will give you the distance the edge of the washer's door will be from the wall...^Ivan

What is the average time for towels drying 

Asked by: Zorica
Regrettably, our specifications for the LG 4.5 cu.ft. Smart Wi-Fi Enabled All-In-One Washer/Dryer with TurboWash® Technology, Model # WM3998HBA do not list drying cycle times. The automatic programs for the dry cycle use electronic sensors that measure the temperature of the exhaust to increase or decrease drying temperatures for faster reaction time and tighter temperature control. You can also use the Time function to change the drying time according to your maximum load. Drying times can be selected from 30minutes up to 210 minutes in 30-minute increments...^Ivan
