The GXSL55F is a straightforward single-stage under-sink filter, so there is little to go wrong beyond the cartridge and its seals. Slow flow at the filtered outlet almost always means the cartridge is due.
Owners can change cartridges: isolate the supply, relieve pressure at the filtered tap, swap the cartridge, then check for drips for a few minutes with a torch and a paper towel. Any weep that continues after a proper reseat needs the head or the fittings looked at, which is plumbing work.
