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. This is a twist-style bay, the friendlier design: no tools, no housing removal, and the cartridge indexes in only one orientation despite looking symmetric.

Order-day practicalities: expect the first swap to take longer than the box suggests — aged o-rings grip — so budget ten minutes, not five. 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. Hold this constant while shopping: the same EDR4RXD1 family covers this chassis end to end.

How to install the water filter in the PSD2450GRW

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.

What this filter takes out of your water

What it targets	Standard that covers it
Chlorine taste & odor	NSF/ANSI 42 — aesthetic effects
Particulates, Class I	NSF/ANSI 42 — fine sediment
Lead	NSF/ANSI 53 — health effects
Cysts (cryptosporidium, giardia)	NSF/ANSI 53 — microbial
PFOA & PFOS	NSF/ANSI 53 (P473) — varies by cartridge

Coverage above lists what the standard addresses, not a performance claim for any specific cartridge — removal claims vary by certificate, so check the NSF listing for the exact part number you are buying.

PSD2450GRW filter questions

Filter light reset on the Maytag PSD2450GRW — how?

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.

Maytag PSD2450GRW: bypass plug needed without a filter?

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 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.
