My particular refrigerator is a French Door, Bottom Freezer Model in the PFE line, specifically PFE28KSKSS purchased July 2019. You likely have another letter between the last K and the SS that follows it - that is apparently a color code.
It uses water filter RPWFE.
I am a consumer not a repairman and just want to give people a heads up who may not already know that the design of the water filter was changed at some point in the last 6 years. I have no idea when.
This may or may not apply to models starting with DFE, GFE, GFS, GNE, PFH, PFD or GFE models. (standard depth models)
This may or may not apply to models starting with GYE, GYS, PYE, DYE, PWE, ZWE or PYD models. (counter depth models).
^^^These models are listed on the cover of my manual so I thought I'd mention them here. My situation may not apply to your fridge so please check your manual and your filters!
After having trouble replacing a filter, damaging the filter holder, replacing the filter holder, and sort-of damaging yet another filter, I have found that GE changed the design of the water filter.
I have been following the instructions in my refrigerator manual (purchase date 2019) on page 17, and when you are installing a new water filter, it specifically says you have to turn the filter 1/4 turn clockwise after you have seated it and before swinging the filter back into the housing. (You insert the filter with the word FRONT facing upward - then you rotate it 1/4 turn clockwise so that the word FRONT is facing to the right, and then you swing it back into the holder.)
Only today, after struggling to replace my filter, did I discover a tiny paper insert inside the box of my water filter. The last two filters I've removed from the boxes I did not see or feel this. It does not slide out with the filter. I just happened to look inside the box and see it at the bottom when I went to flatten and recycle the box.
The filter insert says, if you have a grey filter holder, DO NOT twist the cartridge.
Well, $%^&@!#$%, I have a grey filter holder. Of course I do. *sigh*
I can only imagine that there was trouble with people not following the instructions before, or rotating too far or not enough, so they made it "easier" by changing the design of the filter and how the tabs line up with receptacles in the housing. Thereby f**king over people who use the refrigerator manual and never saw the insert with the new filters.
If you have a grey filter holder, you DON'T install the new filter with "FRONT" facing up, but facing outward instead. Just gently push the filter into the housing with FRONT facing outward. Everything should line up properly and the filter should seat properly before you swing it back into the housing.
THIS DOES NOT APPLY TO ANYONE WITH A BLACK FILTER HOLDER.
I hope this helps someone.
Have a great day!
