KSSC42QTS00 specifics — where the filter actually lives
The KSSC42QTS00 carries its water filter low on the fresh-food side or behind the base grille in most side-by-side layouts, so expect to clear one shelf edge before you have working room. Mechanically the KSSC42QTS00 uses a twist-in cartridge: the cartridge drops into the keyed seat and locks with a short quarter turn.
The small print owners learn the hard way: run the first gallon or two through a fresh cartridge before drinking — carbon fines are normal — and reset the indicator so the countdown matches reality. The KSS in KSSC42QTS00 is doing real work: KSS generally indicates the side-by-side family, so cross-referencing cartridges by chassis rather than by door style usually keeps you out of the wrong-parts queue. 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
Catalog shorthand: KSS answers to side-by-side; the rest of the catalog answers to the neighboring layout; the water-filter answer is shared. 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
KitchenAid KSSC42QTS00: how do I clear the change-filter light?
Hold the filter-reset control a few seconds after seating the new cartridge; placements vary by control panel, and the KSSC42QTS00 manual’s filter-status page has the exact spot.
Can I run the KitchenAid KSSC42QTS00 with no cartridge installed?
No bypass needed: the EDR3RXD1 bay closes on its own, and running empty simply means the water skips filtration until you seat a new cartridge.
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.
