6 Customer Care Cycles

LG SideKick™ offers six distinct wash cycles, including a special setting for active wear.

Simultaneous or Independent Operation

LG SideKick™ saves time by washing two loads at once or get it all done by washing a small load separately.

Raises Your Washer

LG SideKick™ allows you to easily access laundry for more comfortable loading and unloading in the main washer. Compatible with all new LG Front Load Washers.

What people are saying

Rated 5 out of 5 by from Great features Enough features to fit any type of clothing situation
Date published: 2020-03-17
Rated 5 out of 5 by from Happy with the WM437HWA bought two years ago I delayed reviewing it because, judging from reviews, I though it would break down. It has not!(-; I find it hard to say I "love" a machine, so here are pros and cons. PROS:(1) It's the biggest machine that fits in our small laundry room, and it's plenty big, since it accommodates our extra wide blanket or our King extra deep mattress! (-; (2) really like the many cycle options, particularly the Allergiene cycle, since I no longer have to use the Mite detergent which changed color of sheets; (3) really like the sanitary true steam cycle which disinfects bath and kitchen towels and some underwear; (4) Really Like the hand-wash cycle, because I hate hand washing (5) I love that it is QUIET!(-; since laundry room is right next to master bedroom; (6) I like the sound of the tune at end of cycle-- not annoying and it's cheery. CONS I cannot think of any cons, except that because of reviews two year ago, I spent a lot of time expecting that it would break down. In the hope of preventing malfunctions, I have been diligent in maintenance, particularly in draining the water from, and cleaning, the drain pump filter. I also make sure that I do not pour too much detergent to prevent suds from accumulating in the door seal. I note that at the beginning the machine kept giving code notices and some of the recommended solutions were just non-sensical. I don't remember what I did, but everything worked out. Since warranty just expired, I'm waiting for machine to break down. It has not, and thus have decided to set aside those thoughts. So, after all, I can say that I do love the washing machine! I'm Glad we bought it and we would buy it again!

When will you have your LG WM 4370HKA 4.5 cu ft Ultra Large Capacity Turbo Washer and matching DLEX4370K Electric Dryer available. They are "Out Of Stock" in ALL the Home Depot and Lowes Stores in eastern Massachusetts.

Asked by: Alreadyused
Regrettably, we do not have information on Best Buy's inventory for the ENERGY STAR® Qualified 4.5 cu. ft. Ultra Large Capacity TurboWash® Washer, Model # WM4370HKA and the ENERGY STAR® Qualified LG 7.4 cu.ft. Ultra Large Capacity TurboSteam™ Electric Dryer, Model # DLEX4370K nor do we have information for when or if they have placed an order fulfillment for more inventory on the products. That is proprietary information that only those retailers can give you. You can also ask if those retailers have it online or in one of their other nearby stores so they can have it shipped to your local store so you can pick it up from them or arrange to have it shipped to you...^IFV

I just inherited this 2 year old washer yesterday. I heard that it requires a special "low suddsing" soap. Is that true, and if so, what type of soap should be used? I've also heard that you can use any laundry soap, just way less. I use GAIN.

Asked by: pittipat
The ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity TurboWash® Washer, Model # WM4370HWA is specially designed to use only HE (High-Efficiency) detergent which is available as liquid, or powdered detergent and as detergent pods. These detergents are identifiable by the HE logo on their packaging and you will need to follow the manufacturer's instructions on their use. If using HE Detergent pods, do not place them in the detergent dispenser. They will need to be put directly into the tub before loading your clothes. ^CP

What are the key differences between the WM4370 and the still to be made available WM3900? The website comparison feature shows TurboWash for the 4370 and TurboWash 360 for the 3900, but I'm not sure if there's a difference. Thx.

Based on the specifications that we currently have for the "still to be made available" LG 4.5 cu.ft. Smart wi-fi Enabled Front Load Washer with TurboWash™ 360 Technology, Model # WM3900HBA, the TurboWash™ 360 Technology and TurboWash® 2.0 Technology is a more recent and advanced version of the TurboWash® Technology featured on the WM4370H*A. The WM3900HBA is not a Forced Drain System and it has built-in Wi-Fi which introduces features like Cycle Monitoring and Notification and Energy Monitoring...^IFV
