The SilverCare kit in the WF448AAW lasts for 1000 cycles. To put this in perspective, if you select the SilverCare option for two loads each week, the silver plates will last nearly ten years; four times per week, and it would last five years. Samsung recommends using SilverCare at least once or twice a week to help keep the washdrum odor and mildew-free.
You can determine whether the part is ready to be replaced by pressing the SilverCare and Signal buttons simultaneously. LU1 indicates less than 1000 cycles of SilverCare have been used; when the code reads LU0, more than 1000 cycles have been run, and it's time to replace the part. Samsung recommends scheduling a service appointment to replace the part.
