KSSC42QKS00 specifics — where the filter actually lives
Finding the bay is the easy part — this chassis puts it behind the lower fresh-food trim or base grille in most side-by-side layouts, so expect to clear one shelf edge before you have working room. This is a twist-style bay, the friendlier design: the bay wants the cartridge offered flat, rotated a quarter turn, and nothing more — hand pressure only.
Two quirks worth knowing before you order: flush before the first glass — new carbon beds shed fines for the first gallon or so, which is cosmetic, not contamination. The KSS in KSSC42QKS00 is doing real work: KSS typically codes for side-by-side machines in this catalog, and in that format the water path is long enough that a neglected cartridge shows up as flow drop before it shows up as taste. 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
The KSS prefix sits next to the rest of the catalog in the catalog and the split is cabinet mission: 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. Working from the model code, the KSSC42QKS00 lands somewhere around 2001 to 2005; treat the window as approximate.
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.

KSSC42QKS00 filter questions
How do I reset the filter light on the KitchenAid KSSC42QKS00?
Hold the filter-reset control a few seconds after seating the new cartridge; placements vary by control panel, and the KSSC42QKS00 manual’s filter-status page has the exact spot.
Does the KitchenAid KSSC42QKS00 need a bypass plug when the filter is out?
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 KSSC42QKS00?
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.
