KSSS42FJX00 specifics — where the filter actually lives
The filter bay on the KSSS42FJX00 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. The seat is a twist-in design — one twist to release, one to lock; between them you are holding the entire service procedure.
Two quirks worth knowing before you order: a stubborn first twist when the old o-ring has set, and a change-filter light that will not clear itself until you hold the reset. The KSS in KSSS42FJX00 is doing real work: it usually places the machine in the side-by-side family, a strong hint at the cartridge line, the reset behavior, and the service documentation worth consulting. Read the 00 ending as a revision marker — KitchenAid used it for running changes, none of which touched the EDR5RXD1 bay.
KSS vs the rest of the catalog — what the prefix tells you
The KSS/the rest of the catalog pair divides this family by layout — side-by-side against the neighboring layout, respectively. Filter bays rarely care — the media family carries over more often than not. Model-code reading puts the KSSS42FJX00 at roughly 2000-2004 — treat that as approximately right, not a production guarantee.
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.

KSSS42FJX00 filter questions
How do I reset the filter light on the KitchenAid KSSS42FJX00?
Hold the filter-reset control a few seconds after seating the new cartridge; placements vary by control panel, and the KSSS42FJX00 manual’s filter-status page has the exact spot.
Can I run the KitchenAid KSSS42FJX00 with no cartridge installed?
No — the EDR5RXD1 bay seals on the cartridge itself, so removing it just means unfiltered water until the next change, not a leak.
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 KSSS42FJX00?
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.
