Answer This Question

can my old dryer DLGX8388WM be stacked on new washer WM3400CW? If so, will my old stacking kit WSTK1 work or do I need KSTK4?

Answer This Question

Hi, there! Thank you for sharing your question to us question about your LG Washer (WM3400CW). Yes, your dryer is stackable with the WM3400CW; however, the older WSTK1 stacking kit isn’t needed for this setup. The correct and required kit for the WM3400CW is the LG KSTK4, which securely fits modern 27‑inch LG front‑load washers and ensures proper stability and vibration control. You can explore the full feature list and support details here: https://www.homedepot.com/p/LG-4-5-Cu-Ft-Stackable-Front-Load-Washer-in-White-with-Coldwash-Technology-WM3400CW/312399923.

      Answer This Question

      The LG 27" Laundry Pedestal in Wild Cherry Red, Model # WDP4R, was specifically designed for compatibility with older LG Front Load Washers with a 27" width, and the Energy Star® Certified LG 4.5 cu. Ft. Ultra Large Capacity Front Load Washer, Model # WM3400CV, has a width of 27" so the WDP4R can still be installed under it...^Ivan.

              Can you wash king size comforter in the washer?
              ByMay 26, 2026

              Answer This Question

              A 3.5 cubic feet capacity Front Load Washer has long been considered large enough for most King Size Comforters, so with a capacity of 4.5 cubic feet, the ENERGY STAR® Certified LG 4.5 cu. Ft. Ultra Large Capacity Stackable Front Load Washer with Coldwash™ and 6Motion™ Technology in Graphite Steel, Model # WM3400CV, will accommodate most, if not all, King Size comforters depending on how bulky they are...^Ivan.

                Average washing machine
                I bought this machine about a month ago because I have a small space, so my options were limited. Not in love with it. It definitely takes too long to wash a relatively small load. There is water left in the detergent drawer, which was mentioned in another review. After reading other reviews, I don’t have high hopes for this product. It requires a lot of care such as wiping down the gaskets regularly. No error codes or leaks yet…I’m holding my breath.

                  Product leaks after Home Depot installed it

                  Response from LG Digital Customer CareMay 7, 2026
                  Hi, there. Thank you for reaching out, and we understand the importance of having your LG Washer (WM3400CW) model operating without leaks. Since the leak happened right after the Home Depot installation of your unit, (1) please inspect the water supply and drain hose connections at the back of the unit. (2) Make sure the hot and cold water inlet hoses are securely tightened and that the rubber washers are properly seated in the hose connectors. (3) Also, check that the drain hose is correctly placed in the standpipe and not inserted too deeply, as this can lead to siphoning or backup, causing water to appear at the base of the machine. For more guidance, visit https://www.lg.com/us/support/help-library/lg-washer-why-is-my-front-load-washing-machine-leaking--1431986512448. We’d be glad to take a closer look into this for you.

                  Don’t Buy!!!
                  Don’t Buy!!! LG has an issue with the finish and the paint peels on the top of machines. They will NOT fix it Or offer any compensation. The warranty won’t cover cosmetics, so now I have a machine that looks like it’s been through a chemical war. Very disappointed!!

                  Hi, there. Thank you for taking the time to share this with us. We understand the importance of having your LG Washer (WM3400CV) model maintain its appearance as well as its performance. One helpful step you can try is to ensure the surface is kept dry after each use, as moisture sitting on the top panel for extended periods can affect the finish over time. For additional guidance, visit https://www.lg.com/us/support/product/lg-WM3400CV.ASSEVUS. We’d like to learn more about your experience and explore what options may be available.

                      Great washer. Had our last LG for 15 years and tons of laundry. High hopes for this one. Similar operation. Have it in a closet so couldn’t get the largest size, but only around 0.5 sq.ft. less capacity. Make sure to measure your space. Outer casings are not all a standard size.

                      This is a great, high capacity washing machine that is easy to use and gets clothes, linens and towels very clean. I have this in my short term rental property and guests often comment how great it is.

                      Water leak and clothing remains dampened
                      I am writing to formally request a replacement for a defective LG washing machine purchased on 01/04/26 at Home Depot Rancho Cucamonga and delivered on 01/07/26. The unit leaked during its first use, and despite multiple service visits and conflicting instructions from Home Depot and LG, the issue remains unresolved. To date, the following actions have been taken: - 01/15/26: A technician inspected the hoses and advised that if leaking continued, the unit should be replaced by Home Depot. - Subsequent use resulted in soaked clothes and significant leaking. - I have been directed back and forth between the Home Depot store, the appliance department, and LG customer service, including a frustrating hour-long troubleshooting session via video call. - 01/26/26: A third-party technician inspected the machine and stated his manager would also need to inspect it. Home Depot later claimed there was no report of this inspection and scheduled another appointment for 01/28/26. I am extremely dissatisfied with this experience. I purchased a new appliance that was defective upon delivery, and I have now been asked to facilitate four separate inspections. I am requesting that you honor the replacement of this defective machine immediately.

                      Hi, Dora. Thank you for reaching out about your LG Washer (WM3400CW) model. We understand the importance of having a new washer perform exactly as expected from the very first use. Since the unit leaked during its first cycle, one helpful step you can try—once the washer is accessible—is to check that the drain hose is secured at the correct height (between 29–96 inches) and that it isn’t inserted too far into the standpipe. An incorrect drain‑hose position can cause water to backflow or leak during operation. For more guidance, visit https://www.lg.com/us/support/help-library/lg-washer-why-is-my-front-load-washing-machine-leaking--1431986512448. We’d like to take a closer look into your case and review the service history so we can assist you properly. Please send us an email at lgdigitalcare@lg.sprinklrsupport.com.
