The Whirlpool 285620 Washer for Washing Machine provides secure spacing and load distribution to support the proper assembly and operation of compatible washer components. This replacement washer is designed to fit specific washing machine assemblies, where it functions as a spacer and bearing surface between fastening parts. It works by evenly distributing pressure, reducing unnecessary wear, and helping maintain the correct alignment of connected components during agitation and spin cycles.
