KSSS42FKT00 specifics — where the filter actually lives
On the KSSS42FKT00, the cartridge low on the fresh-food side or behind the base grille in most side-by-side layouts, the same estate every side-by-side refrigerator in this family uses. Mechanically it is a quarter-turn twist-in seat: release is counterclockwise, seating is clockwise, and the stops are firm enough that you cannot overshoot.
The recurring owner notes: the line is still live when you open the bay, so keep a towel in reach, and expect the filter-status light to need a reset before it believes the new cartridge. KSS reads as a chassis statement rather than a trim code: the KSS tag is how the catalog sorts side-by-side machines — carry it into any fit checker and the right cartridge line follows. Suffix 00 = production revision; filtration hardware was not part of the revision cycle.
KSS vs the rest of the catalog — what the prefix tells you
KSS versus the rest of the catalog is the first fork in the parts catalog: KSS machines are side-by-side; the rest of the catalog machines are the neighboring layout. Both draw from the same cartridge line, which is why fit charts list them together. The KSSS42FKT00 code suggests roughly 2001 to 2005 production — approximately right, which is all a parts search needs.
Swap it in 5 minutes
- Twist the old cartridge a quarter turn counterclockwise and pull it straight down — keep a towel in reach for the dribble.
- Fill the new cartridge with cold tap water so the chamber is not fighting an air pocket.
- Offer the new cartridge to the bay, push up, and twist a quarter turn clockwise until the stop catches.
- Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.

KSSS42FKT00 filter questions
How do I reset the filter light on the KitchenAid KSSS42FKT00?
Seat the new cartridge first, then hold the filter-reset control for a few seconds until the status light clears — the exact button placement varies by control panel, so check the KSSS42FKT00 owner’s manual page for filter status.
Can I run the KitchenAid KSSS42FKT00 with no cartridge installed?
No — run it empty if you like; the EDR5RXD1 bay needs no bypass plug, it simply passes water through untreated.
Are off-brand filters safe for a KitchenAid refrigerator?
Certified aftermarket cartridges are built to the same NSF test standards as the OEM part, and federal warranty law (Magnuson-Moss) protects your coverage when you use them.
Why is the OEM EDR5RXD1 cartridge so much more expensive?
Part of the OEM price is the badge and the distribution chain. Certified alternatives meet the same test standards at a lower unit price, especially in multi-packs.
How often should I replace the filter in my KSSS42FKT00?
Every six months or at the rated gallon capacity, whichever comes first — the EDR5RXD1 class cartridges all share that service interval.
Do I need to turn off the water supply to change it?
No — the bay is designed for a live swap. Expect a small dribble, keep a towel in reach, and flush a couple of gallons through the new cartridge before the first glass.
