KSBS25INBL01 specifics — where the filter actually lives
The KSBS25INBL01 carries its water filter in the lower fresh-food zone in most side-by-side layouts, knee height or below, a deliberate placement that keeps the swap away from the door seals and drawer rails. This is a twist-style bay, the friendlier design: no tools, no housing removal, and the cartridge indexes in only one orientation despite looking symmetric.
The recurring owner notes: 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 KSB prefix is the tell: in this catalog KSB is the side-by-side variant marker; internal layouts vary, the bay layout does not. Read the 01 ending as a revision marker — KitchenAid used it for running changes, none of which touched the EDR3RXD1 bay.
KSB vs KSR — what the prefix tells you
The KSB prefix sits next to KSR in the catalog and the split is cabinet mission: Chassis first: side-by-side variant (KSB) versus side-by-side chassis (KSR). The shared cartridge line covers both without adaptation. Under the cabinet differences one thing holds: the EDR3RXD1 line — which is why fit listings key on chassis rather than door style.
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.

KSBS25INBL01 filter questions
KSBS25INBL01 filter light will not turn off — what is the reset step?
Lock in the new cartridge first, then hold the reset control for a few seconds — the KSBS25INBL01 manual documents the button for each panel variant.
Is a bypass plug required for the KSBS25INBL01 when the cartridge is removed?
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 KSBS25INBL01?
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.
