WRX988SIBB01 specifics — where the filter actually lives
On the WRX988SIBB01, the cartridge inside the fresh-food cavity, upper zone in most French-door builds, a spot that survives trim changes across the WRX run. The seat is a twist-in design — the ears on the cartridge neck are the guide — line them up, lift into the seat, and quarter-turn home.
Two quirks worth knowing before you order: plan on a towel for the first pull — sitting water in the line — and a five-second reset hold once the fresh cartridge is in. WRX is not a trim code, it is a chassis statement: when Whirlpool stamps WRX on the plate it is sorting the machine into the French-door with exterior dispenser class — same water path, same cartridge, different cabinet. That trailing 01 is the revision counter: WRX chassis revisions share one water path, so the cartridge order never changes with it.
WRX vs WRT — what the prefix tells you
WRX or WRT: the badge difference that does (and does not) change the filter order. WRX answers to French-door with exterior dispenser; WRT answers to top-freezer; the water-filter answer is shared. The constant across every trim of this machine is the cartridge line — this chassis drinks from the EDR2RXD2 family, one of the most cross-referenced cartridges in the Whirlpool catalog.
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.

WRX988SIBB01 filter questions
How do I reset the filter light on the Whirlpool WRX988SIBB01?
Seat the new cartridge first, then hold the filter-reset control for a few seconds until the status light clears — the exact button placement varies by control panel, so check the WRX988SIBB01 owner’s manual page for filter status.
Whirlpool WRX988SIBB01: bypass plug needed without a filter?
No — run it empty if you like; the EDR2RXD2 bay needs no bypass plug, it simply passes water through untreated.
Are off-brand filters safe for a Whirlpool 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 EDR2RXD2 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 WRX988SIBB01?
Every six months or at the rated gallon capacity, whichever comes first — the EDR2RXD2 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.
