WRF550CDHZ01 specifics — where the filter actually lives
The WRF550CDHZ01 carries its water filter 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. This is a twist-style bay, the friendlier design: a quarter turn one way to release, the other to seat, and the only tool you need is a towel for the drip.
Before you click buy, two things: the reset control is the step everyone skips; the light will not acknowledge a new cartridge on its own. WRF is not a trim code, it is a chassis statement: when Whirlpool stamps WRF on the plate it is sorting the machine into the French-door bottom-freezer class — same water path, same cartridge, different cabinet. A -01 style suffix means running production revisions; filter fit stayed constant across the whole run.
WRF vs WRS — what the prefix tells you
WRF or WRS: the badge difference that does (and does not) change the filter order. The door count differs — French-door bottom-freezer against side-by-side — but the bay and the cartridge order do not. The constant across every trim of this machine is the cartridge line — 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.

WRF550CDHZ01 filter questions
Reset procedure for the change-filter alert on the WRF550CDHZ01?
Press and hold the reset control until the light clears (a few seconds), with the new cartridge already seated — the WRF550CDHZ01 owner’s manual lists the button location for your control panel.
Is a bypass plug required for the WRF550CDHZ01 when the cartridge is removed?
You can, but unfiltered — the EDR4RXD1 bay needs no bypass plug; it just passes water through without filtering while the cartridge is out.
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 WRF550CDHZ01?
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.
