KSSC42QTS00 specifics — where the filter actually lives
The filter bay on the KSSC42QTS00 low on the fresh-food side or behind the base grille in most side-by-side layouts — usually a kneeling-height or shoulder-height swap, not a teardown. The seat is a twist-in design — look for the index lugs, offer the cartridge, and rotate until they disappear into the housing.
Owners of the KSSC42QTS00 report the same friction points: carbon fines in the first pours are normal for a fresh bed, and the filter timer only restarts when you hold the reset. Decode the plate and the parts question answers itself: in this catalog KSS is the side-by-side marker; internal layouts vary, the bay layout does not. The -00 tail tracks the revision ladder — each rung shares the identical EDR3RXD1 bay.
KSS vs the rest of the catalog — what the prefix tells you
The catalog pairs KSS with the rest of the catalog, and the split matters at order time: KSS means side-by-side, the rest of the catalog means the neighboring layout. For filter shopping the distinction matters less than you would think — same line, different cabinet. Model-code reading puts the KSSC42QTS00 at roughly 2007 to 2011 — 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.

KSSC42QTS00 filter questions
KSSC42QTS00 filter light will not turn off — what is the reset step?
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 KSSC42QTS00 owner’s manual page for filter status.
Can I run the KitchenAid KSSC42QTS00 with no cartridge installed?
The bay self-seals: with no cartridge the KSSC42QTS00 still dispenses, just unfiltered. No bypass plug exists for this line.
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 EDR3RXD1 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 KSSC42QTS00?
Every six months or at the rated gallon capacity, whichever comes first — the EDR3RXD1 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.
