4.5 cu. ft. Ultra Large Capacity Stackable Front Load Washer with Coldwash and 6 Motion Technology in Graphite Steel

As with all other LG Front-Load washers, and their matching dryers, the Energy Star® Certified LG 4.5 Cu. Ft. Ultra Large Front Load Washer in White with AI Wash and Coldwash™ Technology, Model # WM3420CW, is a stackable unit. You will need the 27" LG Stacking Kit, Model # KSTK4, to stack a compatible dryer on the washer...^Ivan.

Did you mean "pedestal"? You wrote "pet stool!. Both 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, and your older LG Model # WM3570HVA share the same 27-inch width and use LG's standard post-2009 pedestal mounting footprint, so the LG Model # WM3400CV washer is physically compatible with the older pedestal used on the LG Model # WM3570HVA. Your older Graphite Steel washer uses the 27-inch LG Laundry Pedestal (Model # WDP4V). LG's newer WM3400CV (Graphite Steel) is officially paired with the updated WDP6V pedestal, which maintains the exact same 27-inch width and mounting bolt pattern. Both the WM3570HVA ("V") and the WM3400CV ("V") share LG's Graphite Steel finish; so your existing WDP4V pedestal will match the new washer's color. When mounting the new washer onto your old pedestal, make sure you reuse the four metal mounting brackets and 16 screws from the old setup. Because your new WM3400CV will not come with pedestal mounting hardware in the box, check that all brackets and bolts are intact before your old washer is hauled away. If you are having a big-box store like Home Depot deliver your new washer, some third-party delivery crews refuse to lift a new machine onto an existing, older pedestal due to liability rules. Confirm with Home Depot ahead of time whether they will mount the new washer onto your existing pedestal or if you will need to lift and bolt it on yourself...^Ivan.

As with ALL other LG front-load washers, the door for the Energy Star® Certified LG 4.5 Cu. Ft. Ultra Large Front Load Washer in White with AI Wash and Coldwash™ Technology, Model # WM3420CW, is irreversible. A vast majority of front-load washers on the market, regardless of brand or manufacturer, are strictly fixed to open to the left, but there are prominent manufacturer exceptions that feature fully reversible doors. For LG Front-Load Washers, LG explicitly locks its front-load washer doors to swing only to the left, because unlike dryers, a washing machine door features complex safety component wiring. It houses strong high-voltage electronic door-latching switches, emergency locks, and safety logic sensors designed to prevent the machine from launching a cycle while open. Rerouting this high-voltage wiring harness inside the cabinet frame adds production complexity. A front-load washer door holds back gallons of sloshing water. To ensure a completely watertight seal, the glass bowl geometry and rubber bellows gasket are precisely pressure-aligned to close against a fixed hinge...^Ivan.

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, does not have a dedicated "Add Garment" or "Add Item" button on its control panel. However, even without that specific button, However, you can still easily add forgotten clothes to a cycle that has already started by pausing the wash cycle and unlocking the door provided it is safe to do so. The machine will prevent the door from unlocking if it determines that opening it would cause a safety hazard or a mess. The door will remain locked if the water level inside the drum is high enough to spill out onto your floor, the water temperature has already reached scalding levels (during heavy-duty or hot sanitizing cycles), or if the machine has progressed past the halfway point and entered its high-speed spin routines. To add clothes mid-cycle: 1. Press the Start/Pause button once while the cycle is running. 2. Wait a few moments for the drum to come to a complete stop. 3. Listen for the click/double-unlock sound. The door lock icon on the digital display will turn off. 4. Open the door, toss in your item, shut the door firmly, and press Start/Pause again to resume washing...^Ivan.

Your ENERGY STAR® Qualified LG 7.4 cu. Ft. Ultra Large Capacity SteamDryer™ w/ NFC Tag On, Model # DLEX3370V, is stackable and can be stacked on this 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, or any other 27" standalone LG Front Load washer, using the 27" LG Stacking Kit, Model # KSTK4, that is specifically designed for compatibility with 27" LG front Load washers and their matching electric/gas dryers...^Ivan.

The listed width and depth dimensions for the ENERGY STAR® Most Efficient / ENERGY STAR® Certified LG 4.5 Cu. Ft. Ultra Large Front Load Washer in White with AI Wash and Coldwash™ Technology, Model # WM3420CW, are 27" x 30 1/4". However, that depth includes the slight bulge of the door and rear hardware contours. The actual structural cabinet depth at the very bottom base is roughly 28 inches. Because of how the washer balances its weight, you must use a drain pan that the entire machine fits completely inside. You cannot use a pan that sits strictly "underneath" or flush with the bare minimum 27" x 28" footprint. Front-load washers spin at exceptionally high speeds (up to 1,260 RPM for this model). If the washer's leveling legs rest directly on the edge or lip of a pan, the heavy vibration will instantly crack the pan or throw the machine violently out of balance. The entire Unit must sit inside, and the 4 leveling legs must rest flat on the wide, inner basin floor of the pan. You need a heavy-duty washer pan with minimum interior dimensions of 30" Wide x 32" Deep. A standard 30" x 30" pan will be too shallow to clear the back plumbing connections and front leg extensions...^Ivan.

Which type of king-size comforter are you inquiring about?. The Energy Star® Most Efficient / Energy Star® Certified LG 4.5 Cu. Ft. Ultra Large Front Load Washer in White with AI Wash and Coldwash™ Technology, Model # WM3420CW, will not accommodate just any type of King size comforter. With an ultra-large capacity of 4.5 cubic feet, this front-load washer can comfortably fit standard, light-to-medium weight King size comforters (such as standard down or down-alternative options), but it will struggle with thick, overfilled, heavy-duty, or densely packed winter King comforters. According to laundry expert consensus, your bedding should fit loosely into the stainless steel drum, ideally leaving about one-third of the space completely free at the top. If you have to forcefully pack, compress, or jam the comforter into the drum just to get the glass door to click shut, it is too big. The fabric needs enough loose clearance to physically tumble and drop so water and soap can penetrate it. Densely packed, thick down comforters absorb a massive volume of water, expanding rapidly and becoming heavy enough to cause drum imbalance errors during high-speed spin cycles...^Ivan.

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, has a Speed Wash cycle, which is its own separate dial position on your washer. Because it is a standalone cycle, you have the freedom to change the water temperature, add an extra rinse, or change the spin speed manually. The Quick Cycle is a button option on the control panel rather than a spot on the main dial. You use it to cut corners on a standard load when you are in a mild hurry. If you select the Normal or Casual cycle (which might normally take 50 to 60 minutes) and then press the Quick Cycle modifier button, the machine adjusts its internal algorithm to shorten the agitation and rinsing phases, lopping roughly half the total runtime off the timer...^Ivan.
