KBFA25ERSS01 specifics — where the filter actually lives
The KBFA25ERSS01 carries its water filter top of the fresh-food cavity, above the crisper in most bottom-freezer layouts, a deliberate placement that keeps the swap away from the door seals and drawer rails. This is a twist-style bay, the friendlier design: align the ears, seat it, and rotate until the stop catches — a five-minute job start to finish.
Field notes: the line is still live when you open the bay, so keep a towel in reach, and expect the filter-status light to need a reset before it believes the new cartridge. The KBF in KBFA25ERSS01 is doing real work: it usually marks a bottom-freezer layout, which means shared cartridge economics — one media family, dozens of cabinet variants, all drinking from the same parts line. The two-digit 01 tail is revision bookkeeping. Badge position and shelf trim moved around; the bay geometry did not.
KBF vs KFI — what the prefix tells you
Know your KBF from your KFI and the cartridge question halves: KBF means bottom-freezer, KFI means French-door. For filter shopping the distinction matters less than you would think — same line, different cabinet. The KBFA25ERSS01 code suggests roughly 2005 to 2009 production — approximately right, which is all a parts search needs.
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.

KBFA25ERSS01 filter questions
How do I reset the filter light on the Kenmore KBFA25ERSS01?
Press and hold the reset control until the light clears (a few seconds), with the new cartridge already seated — the KBFA25ERSS01 owner’s manual lists the button location for your control panel.
Can I run the Kenmore KBFA25ERSS01 with no cartridge installed?
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 Kenmore 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 KBFA25ERSS01?
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.
