WRX735SDHV06 specifics — where the filter actually lives
Where the filter actually lives: top-left of the fresh-food compartment in most French-door layouts, away from the door bins, so expect to clear one shelf edge before you have working room. Mechanically the WRX735SDHV06 uses a twist-in cartridge: the ears on the cartridge neck are the guide — line them up, lift into the seat, and quarter-turn home.
Owners of the WRX735SDHV06 report the same friction points: a stiff first removal on builds that sat on the same cartridge for years, and an indicator light that wants a manual reset after a non-OEM cartridge is seated. The WRX in WRX735SDHV06 is doing real work: 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. The two-digit 06 tail is revision bookkeeping. Badge position and shelf trim moved around; the bay geometry did not.
WRX vs WRT — what the prefix tells you
WRX versus WRT is the first fork in the parts catalog: 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. Official listing data places the WRX735SDHV06 in 2017 to 2021 — useful, because cartridge revisions tend to track production windows.
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.

WRX735SDHV06 filter questions
Clearing the filter status light on a Whirlpool WRX735SDHV06?
Hold the filter-reset control a few seconds after seating the new cartridge; placements vary by control panel, and the WRX735SDHV06 manual’s filter-status page has the exact spot.
Is a bypass plug required for the WRX735SDHV06 when the cartridge is removed?
No cap needed — the EDR4RXD1 bay passes water unfiltered while empty; it does not leak, it just skips filtration.
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 WRX735SDHV06?
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.
