KBFS20ETSS00 specifics — where the filter actually lives
The KBFS20ETSS00 carries its water filter in the top third of the fresh-food compartment in most bottom-freezer builds, so expect to clear one shelf edge before you have working room. The seat is a twist-in design — a quarter turn one way to release, the other to seat, and the only tool you need is a towel for the drip.
Two quirks worth knowing before you order: keep a folded towel under the bay before you open it; the line holds a cup of water even with the valve shut. Decode the plate and the parts question answers itself: KBF typically codes for bottom-freezer 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. Revision 00 changed trim details, not the water circuit; order with confidence by model stem.
KBF vs KFI — what the prefix tells you
The catalog pairs KBF with KFI, and the split matters at order time: KBF covers bottom-freezer, while KFI covers French-door. The cartridge line is usually shared across both — order by chassis, not by door count. Model-code reading puts the KBFS20ETSS00 at roughly 2007-2011 — 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.

KBFS20ETSS00 filter questions
Filter light reset on the KitchenAid KBFS20ETSS00 — how?
The reset is a press-and-hold on the filter control with the cartridge in place; check the KBFS20ETSS00 owner’s manual for where that control sits on your panel.
Running the KBFS20ETSS00 with an empty filter bay — does it need a cap?
Nothing to buy — the EDR4RXD1 housing closes without a cartridge; water runs unfiltered until the next one goes in.
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 KBFS20ETSS00?
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.
