A:Answer Hi, the LG - TurboWash 4.3 Cu. Ft. 12-Cycle High-Efficiency Steam Front-Loading Washer, Model # WM3570HWA is desgined to be stacked on its matching gas or electric dryers, model #s DLGX3571W and the DLEX3570W and you would need the Stacking Kit Model # KSTK1 to stack the units. Both the Washer and Dryer have a width of 27" and since the DLE3170W Dryer also uses the same Stacking Kit and alos has a width of 27", you should be able to stack it on the WM3570HWA washer...^IFV
