Fast Forward Your Wash

Give big loads the same great clean while cutting your wash time by up to 30 minutes* with LG’s enhanced TurboWash® technology.

*1. Compared to an LG front load washer without TurboWash®. Based on AHAM-HLW-1-2010 test protocol. Cotton / Normal or comparable cycle at default settings, 8 lb. loads. Excludes quick wash or comparable cycles intended for small, lightly soiled loads only.

Deep Clean With Steam

Our steam technology gently but powerfully penetrates fabrics to virtually eliminate dirt, odors and wrinkles.

For Small Loads
that Can’t Wait

Whether it’s your kids’ favorite shirt, yoga pants or a school uniform, washing a full load seems wasteful for just a few pieces. Now you can wash small loads that just can’t wait with the LG SideKick™ Pedestal Washer or wash two loads at once to save time.

Rated 5 out of 5 by from Efficient. All the program I need...and more. I’ve only had it for a month so I can’t assess durability. But I can attest to it’s efficiency, quiet operation, clear controls, drying efficiency. We’re confident we made a good choice.

Rated 4 out of 5 by from Good features on this washer! Good going - so far - Even though I would expect it to be a bit more 'quieter' whenever the "gears are going!" At first, it gave me the impression that the 'gears' were 'grinding' one another ... But I'm 'guessing' that the way it is .... (Regarding the next question, "recommending it to someone" ... I'll do a 'follow up' here (even though it is NOT a 'follow up' ) ... .. I would, w/ the reservation about the 'noisy gears' so, that someone would not be caught by surprise!

Rated 5 out of 5 by from Great Features I bought this machine because my old one died. I am so glad I did, it works great. It is so easy to use even my 8 year old loves to help with the laundry.

Rated 5 out of 5 by from Great addition to our laundry room! Since we got this machine doing laundry has become more enjoyable. With the prewash and the ability to select how soiled clothes are ensures that the clothes come out of the wash without any lingering stains or clinging deodorant smells in the underarms.

I have only 80 degree tap water available in laundry room. Will this machine get water hot? Can I still use steam features?

Asked by: zguillory
To provide optimum washing performance, it is recommended that the hot water temperature for your gas of electric water heater should be set at 120˚-135˚F (48˚-57˚C) and the cold water at 60˚F (15˚C) for the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity TurboWash® Washer, Model # WM3770HWA. YOu will not be able to get hot water if your water is only 80˚F (not sure if your temperature is ˚F or ˚C˚?) If it is 80˚C then that is 176˚F. Water turns to steam at 100˚C (212˚F) at standard pressure. At lower pressures, such as atbthe top of high mountains, water boils at a lower temperature than the nominal 100˚C (212˚F) and if heated further, it becomes superheated steam...^IFV

which models of washing machines are available with an alternate swing

Asked by: ColeHansen

Does the WM3770HVA & the WM4370HKA and matching dryers all have reversible doors?Due to drain we location we need the washer with the hinge on the right. Which is the newer model & differences of the WM4370HKA vs the WM3770HVA? Does 3770 have drain/spin?

Asked by: EileenK
Hi EileenK. Regrettably, neither the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity TurboWash® Washer, Model # WM3770HVA, the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity TurboWash® Washer, Model # WM4370HVA, nor any of our LG Front Load Washers have a reversible door. Their matching dryers do have reversible doors. Both of these washers were released at the same time. The WM3770HVA does not have a Drain + Spin feature, so that is one of the differences in the washers. The WM4370HVA also has a Hand Wash/Wool cycle, and features a Drum Light...^IFV

Does this unit and matching gas dryer allow you to get alerts on your cell phone when a cycle is complete?  Can you start/stop the washer or dryer with the app?   Thank you.  

Asked by: JosephG
