PSD2450GRW specifics — where the filter actually lives
The filter bay on the PSD2450GRW inside the fresh-food cavity, position varying with dispenser spec, a spot that survives trim changes across the refrigerator run. Mechanically the PSD2450GRW uses a twist-in cartridge: offer the cartridge, feel the base o-ring register, and lock it by geometry rather than by force.
Practical notes from the install forums: plan on a towel for the first pull — sitting water in the line — and a five-second reset hold once the fresh cartridge is in. Whatever the badge on the door says, the parts reality is the EDR4RXD1 cartridge family is what every fit listing for this chassis resolves to, OEM and certified alternative alike. Finish codes such as RW change the look, not the plumbing — order the cartridge by model, ignore the finish letter.
Reading the PSD2450GRW model code — what the digits tell you
Working from the model code, the PSD2450GRW lands somewhere around 2017-2021; treat the window as approximate. Shopping shorthand for this model: the PSD2450GRW and its siblings all drink from the EDR4RXD1 line, which keeps the parts search short.
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.

PSD2450GRW filter questions
Maytag PSD2450GRW: how do I clear the change-filter light?
Hold the filter-reset control a few seconds after seating the new cartridge; placements vary by control panel, and the PSD2450GRW manual’s filter-status page has the exact spot.
Running the PSD2450GRW with an empty filter bay — does it need a cap?
No — run it empty if you like; the EDR4RXD1 bay needs no bypass plug, it simply passes water through untreated.
Are off-brand filters safe for a Maytag 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 PSD2450GRW?
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.
