WRX735SDHV09 specifics — where the filter actually lives
The filter bay on the WRX735SDHV09 inside the fresh-food cavity, upper zone in most French-door builds — usually a kneeling-height or shoulder-height swap, not a teardown. It is a twist-lock bay: the cartridge drops into the keyed seat and locks with a short quarter turn.
Owners of the WRX735SDHV09 report the same friction points: the first removal takes more force than every later one, and skipping the reset leaves a change-light glaring at a perfectly fresh cartridge. The WRX prefix is the tell: WRX is Whirlpool’s French-door with exterior dispenser designation proper, and the service literature files every one of these under the same cartridge line. The 09 suffix here is a revision index, not a different machine — trim and door hardware can shift between revisions, the filter bay does not.
WRX vs WRT — what the prefix tells you
Know your WRX from your WRT and the cartridge question halves: French-door with exterior dispenser versus top-freezer. Both generations draw from the same cartridge pool, so the prefix is a fit-check, not a barrier. Model years 2017 to 2021 — the manufacturer-stated window for the WRX735SDHV09, 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.

WRX735SDHV09 filter questions
How to reset the water filter indicator: Whirlpool WRX735SDHV09?
Press and hold the reset control until the light clears (a few seconds), with the new cartridge already seated — the WRX735SDHV09 owner’s manual lists the button location for your control panel.
Will the Whirlpool WRX735SDHV09 dispense water without a filter cartridge?
The bay self-seals: with no cartridge the WRX735SDHV09 still dispenses, just unfiltered. No bypass plug exists for this line.
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 EDR1RXD1 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 WRX735SDHV09?
Every six months or at the rated gallon capacity, whichever comes first — the EDR1RXD1 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.
