KRFF302ESS01 specifics — where the filter actually lives
Finding the bay is the easy part — this chassis puts it high on the fresh-food side in most French-door layouts — upper back or left wall, so expect to clear one shelf edge before you have working room. The seat is a twist-in design — align the ears, seat it, and rotate until the stop catches — a five-minute job start to finish.
Practical notes from the install forums: 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 badge reads KRFF302ESS01, but the chassis reads KRF: KitchenAid uses it across the French-door bottom-freezer range, which means shared cartridge economics — one media family, dozens of cabinet variants, all drinking from the same parts catalog. The -01 tail tracks the revision ladder — each rung shares the identical EDR4RXD1 bay.
KRF vs KSR — what the prefix tells you
The KRF/KSR pair divides this family by layout — KRF means French-door bottom-freezer, KSR means side-by-side chassis. For filter shopping the distinction matters less than you would think — same line, different cabinet. Model years 2015-2019 — the manufacturer-stated window for the KRFF302ESS01, per the official efficiency listing.
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.

KRFF302ESS01 filter questions
Filter light reset on the KitchenAid KRFF302ESS01 — how?
With the new cartridge seated, press and hold the filter reset until the light clears — panel placement differs, so the KRFF302ESS01 manual’s filter section has the exact control for your trim.
Will the KitchenAid KRFF302ESS01 dispense water without a filter cartridge?
You can, but unfiltered — the EDR4RXD1 bay needs no bypass plug; it just passes water through without filtering while the cartridge is out.
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 EDR4RXD1 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 KRFF302ESS01?
Every six months or at the rated gallon capacity, whichever comes first — the EDR4RXD1 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.
