WRX735SDHZ01 specifics — where the filter actually lives
On the WRX735SDHZ01, the cartridge upper rear of the fresh-food section in most French-door builds with interior dispensers, so expect to clear one shelf edge before you have working room. It is a twist-lock bay: half a turn of wrist work in each direction is the whole procedure; everything else is towel management.
The recurring owner notes: a stubborn first twist when the old o-ring has set, and a change-filter light that will not clear itself until you hold the reset. One prefix, one chassis family: the WRX run is Whirlpool’s French-door with exterior dispenser series; across the run, the filter bay is one of the constants. 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
The WRX/WRT pair divides this family by layout — WRX covers French-door with exterior dispenser, while WRT covers top-freezer. The cartridge line is usually shared across both — order by chassis, not by door count. The listed build window for the WRX735SDHZ01 is 2017-2021, per the official record — the bracket that matters for cartridge generation.
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.

WRX735SDHZ01 filter questions
Whirlpool WRX735SDHZ01: how do I clear the change-filter light?
With the new cartridge seated, press and hold the filter reset until the light clears — panel placement differs, so the WRX735SDHZ01 manual’s filter section has the exact control for your trim.
Whirlpool WRX735SDHZ01: bypass plug needed without a filter?
No — run it empty if you like; the EDR4RXD1 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 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 WRX735SDHZ01?
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.
