WRX735SDBM03 specifics — where the filter actually lives
The WRX735SDBM03 carries its water filter inside the fresh-food cavity, upper zone in most French-door builds, the same estate every French-door with exterior dispenser refrigerator in this family uses. It is a twist-lock bay: no tools, no housing removal, and the cartridge indexes in only one orientation despite looking symmetric.
Order-day practicalities: expect dribble at the bay on removal even with the supply off, and remember the indicator will not self-clear — hold the reset control. WRX is not a trim code, it is a chassis statement: Whirlpool uses it across the French-door with exterior dispenser range, which means shared cartridge economics — one media family, dozens of cabinet variants, all drinking from the same parts catalog. The 03 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
The catalog pairs WRX with WRT, and the split matters at order time: WRX machines are French-door with exterior dispenser; WRT machines are top-freezer. Both draw from the same cartridge line, which is why fit charts list them together. Under the cabinet differences one thing holds: the EDR4RXD1 media line; that is the anchor every compatible listing hangs from.
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.

WRX735SDBM03 filter questions
Clearing the filter status light on a Whirlpool WRX735SDBM03?
Lock in the new cartridge first, then hold the reset control for a few seconds — the WRX735SDBM03 manual documents the button for each panel variant.
Can I run the Whirlpool WRX735SDBM03 with no cartridge installed?
No bypass needed: the EDR4RXD1 bay closes on its own, and running empty simply means the water skips filtration until you seat a new cartridge.
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 WRX735SDBM03?
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.
