A:AnswerYes, either pedestal can be used with model WM3500CW. The LG - 27" Laundry Pedestal with Storage Drawer, Model # WDP4* replaced the WDP3* pedestal but they are both designed for compatibility with 27" LG Front Load Washers and Dryers. The only difference between them will be the mounting bracket installation. The WDP4* uses the t-clip installation method. ^Daphane
A:AnswerYes, pedestal WDP4W is compatible with washer WM3570HWA. Use stacking kit KSTK1, https://www.lg.com/us/laundry-accessories/lg-KSTK1-laundry-stacking-kit. ^Daphane
A:AnswerI looked this model up on the Best Buy website. Not trying to be sarcastic, but if you scroll down once it displays the matching washer and 2 pedestals as a recommended package. That's how I bought my units.
A:AnswerWithout knowing the model number of the washer, I cannot confirm compatibility. Please refer to your Owner's Manual for more information. ^Daphane
A:AnswerYes, the pedestal compatible with your model is WDP3W. The LG - 27" Laundry Pedestal with Storage Drawer, Model # WDP4W replaced the WDP3W pedestal but they are both designed for compatibility with 27" LG Front Load Washers and Dryers. The only difference between them will be the mounting bracket installation. The WDP4W uses the t-clip installation method. ^Daphane
