WRX735SDHZ00 specifics — where the filter actually lives
Finding the bay is the easy part — this chassis puts it in the fresh-food compartment, typically the upper back wall in most French-door layouts, a deliberate placement that keeps the swap away from the door seals and drawer rails. It is a twist-lock bay: the bay wants the cartridge offered flat, rotated a quarter turn, and nothing more — hand pressure only.
Order-day practicalities: expect the first swap to take longer than the box suggests — aged o-rings grip — so budget ten minutes, not five. The WRX prefix is the tell: it places the machine in Whirlpool’s French-door with exterior dispenser family, which pins down the cartridge line, the reset behavior, and the service documentation worth consulting. A -00 style suffix means running production revisions; filter fit stayed constant across the whole run.
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. The listed build window for the WRX735SDHZ00 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.

WRX735SDHZ00 filter questions
How do I reset the filter light on the Whirlpool WRX735SDHZ00?
Hold the filter-reset control a few seconds after the swap; the status light clears only with a seated cartridge, and the WRX735SDHZ00 manual maps the control by panel type.
Running the WRX735SDHZ00 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 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 WRX735SDHZ00?
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.
