Mike D Pensacola , FL January 06, 2018 Appliance: Samsung Washer WF431ABP/XAA-0002 Samsung Washer Wf431abp/Xaa-0002 / : Out of balance issue caused by a defective flange/spider on a front loading samsung washer. How to replace Washer Spider Bolt. Since the Tub is Stainless Steel and the Spider is an electrically inferior alloy, Galvanic corrosion will inevitably deteriorate the Spider/Flange to the point of failure. My solution was to bead blast and bake on an epoxy coating to the replacement Spider/Flange to minimize the bimetallic corrosion of this electrically inferior alloy since this is what Samsung is still utilizing. I found the video series done by AppliancePartsPros.com especially well crafted and is in fact why I chose to buy the parts needed from them. I was also impressed with the staff interaction when I called to place my order. The parts arrived packed well and on time. I certainly recommend watching the instructional video for your appliance. 15 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
