Quick take
Use GE XWFE or a replacement that explicitly supports XWFE and GSS23GYPFS. Do not rely only on visual similarity.
Correct filter
GE identifies XWFE as the water-filter accessory for GSS23GYPFS, and model specifications list XWFE water filtration.
Filter location
GE lists the filter location in the upper-right corner for this side-by-side model.
Compatible replacements
A compatible cartridge can lower recurring spend if electronic recognition and sealing are correctly supported.
Purchase checklist
Verify GSS23GYPFS, XWFE compatibility, cartridge certification and seller return policy.
