Rated 5 out of 5 by from Wonderful washer This washer is amazing amd it works wonders. I love being able to use the app to add custom wash modes via nfc.

Rated 1 out of 5 by from Drain pump failed after 3 years of low use. Very disappointed in this washing machine. As the title says, the drain pump failed after 3 years of low usage. The drain pump is a cheaply made plastic part that will undoubtedly fail again. It also requires disassembly of almost the entire washer in order to access it for replacement. I was happy with the washer's performance before this, but the failure of this part seems to be a common issue and a serious design flaw. I will not purchase another LG appliance again after this experience.

Hi, have you discontinued this washer/dryer set? I can’t seem to find them anywhere. Thank you.

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
