I had to replace the water filter base, because I broke it trying to install an after-market water filter. I bought an after-market water filter because the OEM filters are ridiculously expensive. I called the filter supplier, and their customer service guy told me to give the filter an extra hard shove and it would lock into the base. Yeah - it did, but it broke the locking mechanism.
After watching the YouTube video from AppliancePartsPros.com, I ordered the water filter base. It arrived the next day. Installation was 5 minutes. No more after-market filters !!!!!
