After looking online and discovering that others who had used a knockoff brand filter to "save money" had the same problem, I concluded the only solution was to replace the filter housing. Found the one I needed on AppliancePartsPros.com. Most important to me was the video explaining how to replace the filter housing - it made the task a snap to complete. The price was also competitive with other sources. Shipping was half that charged by Samsung. Not only was it cheaper, but it was also super fast. I ordered late morning and it was delivered the next day without paying for express shipping. Impressive!
Right part. Right price. Excellent customer service (shipping and video)!!
