Shuke,
I know this is long, but you asked, so...
Sorry to hear you are having the same problem. I think I've figured it out, and the answer is not good. Sears has been out three times so far and still not fixed.
I bought one of those "mini warranty" type things Sears offers. It's called a "Service Smart Protection Agreement." It was a one time fee, then any repairs to the fridge are covered up to $500 per occurrence for one year. First Sears guy that came out replaced the filter base, saying it was defective, and the filter itself, saying it was defective. That lasted about 1-1/2 months, then water pouring from the housing again.
I asked for a senior tech the next time. He came out, and after I described the problem, he immediately said he knew what it was. (My Kenmore is made by Frigidaire) He said around the end of 2009, Frigidaire either changed the way they manufacture the filters, or changed the supplier who manufactures them for Frigidaire, or both. They are made in Singapore now. Not sure where they were made before. (It's the Pure Source 2 filter, by the way) Ever since the change, they last a very short time, then they begin leaking. The tech said the water stops flowing through as easily, then the water pressure on the inlet side of the filter pushes the filter out just enough to break the seal at the o-rings and it leaks.
By the way -- All of this was told to me "off the record" by the tech. He said Frigidaire has not officially acknowledged this problem. But, they have recommended two fixes for it -- go figure. The first fix is the tech would order a (water) pressure reducer to install on the inlet side of the filter base.
The second fix is he would order me a "bypass filter" which looks just like the water filter, but it has no guts inside it, so the water just flows freely through it. (unfiltered, of course) Then I would have to go to Home Depot and buy an in-line water filter to install on the outside back of the refrigerator myself. I could easily do that, but I spent a lot of money on a top-of-the-line fridge and it's only 2 years old and I have to bastardize it?? No. I asked what are the chances of the pressure reducer working? He said he didn't know. No one has ever tried it. "Everyone else" (read: many others have had this problem) has gone with the bypass.
I had him order the pressure reducer, had to miss work again when he came out to install it. (If I didn't have the warranty, that little plastic part would have been $136. Labor $176.) He installed the part in about ten minutes, and it didn't fix it at all. Water still poured from the housing. So, he got on his laptop and ordered the bypass filter for me. It just arrived today, but I haven't put it in yet.
I even called Frigidaire to try and get some help, and as soon as I told them it was a Kenmore, made by Frigidaire, they wouldn't even talk to me and told me to call Sears.
I also called the internet filter company that I had ordered a filter from during this whole process. (much cheaper than buying from Sears) They were well aware of the problem with this filter, and were happy to refund my money after I shipped it back to them.
I am shocked that no else responded to this post. I'm sure there are others out there having this same issue.
I don't know if this refrigerator fits the definition of a "lemon", but the fact is, according to Sears, the refrigerator cannot be repaired. (Aside from the work around of the outside-mounted filter) I had one of those on my old refrigerator and the quick-connects spontaneously broke one day, causing water to start flowing freely in the kitchen. Thanks goodness I was home at the time and could turn it off. I just remodeled the kitchen and do not want to use an outside mounted filter again. I may go to the Sears store where I bought it and see what they can do for me.
Have you don't anything about your fridge yet?
