WRS315SDHZ00 specifics — where the filter actually lives
Finding the bay is the easy part — this chassis puts it at the base of the fresh-food compartment in most side-by-side builds — grille or lower rear, the same estate every side-by-side refrigerator in this family uses. This is a twist-style bay, the friendlier design: align the ears, seat it, and rotate until the stop catches — a five-minute job start to finish.
Owners of the WRS315SDHZ00 report the same friction points: 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. Read the prefix and the maintenance writes itself: when Whirlpool stamps WRS on the plate it is sorting the machine into the side-by-side class — same water path, same cartridge, different cabinet. That trailing 00 is the revision counter: WRS chassis revisions share one water path, so the cartridge order never changes with it.
WRS vs WRF — what the prefix tells you
The WRS prefix sits next to WRF in the catalog and the split is cabinet mission: Ordering by prefix works because WRS means side-by-side and WRF means French-door bottom-freezer in this catalog — and the cartridge pool overlaps both. One more anchor for the parts search: this chassis drinks from the EDR1RXD1 family, one of the most cross-referenced cartridges in the Whirlpool catalog.
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.

WRS315SDHZ00 filter questions
How do I reset the filter light on the Whirlpool WRS315SDHZ00?
Hold the filter-reset control a few seconds after the swap; the status light clears only with a seated cartridge, and the WRS315SDHZ00 manual maps the control by panel type.
Running the WRS315SDHZ00 with an empty filter bay — does it need a cap?
No — the EDR1RXD1 bay seals on the cartridge itself, so removing it just means unfiltered water until the next change, not a leak.
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 WRS315SDHZ00?
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.
