Frigidaire FRSS26L3AF Water Filter Replacement Guide
Quick Answer
The water filter cleans your drinking water and protects your ice maker from sediment buildup. The telltale sign it has failed or clogged is a slow, trickling flow at the dispenser or smaller than usual ice cubes.
Look, most people ignore the filter light for months. I get it. But here's what actually happens: a clogged filter forces your water inlet valve to work way harder than it's designed to, and those valves cost $40-80 in parts alone. I've watched a neglected filter turn a ten-dollar fix into a $200 repair visit. Don't be that person. This is the easiest maintenance task on any refrigerator, full stop.

What Does the PUREPOUR-PW-1 Code Mean?
OK so this isn't a real error code, it's basically just a maintenance reminder your Frigidaire built in. And honestly, this is the easiest thing you'll ever fix on a fridge. The PW-1 filter runs about $20-40 depending on where you buy it, takes maybe three minutes to swap out, and you don't need a single tool. I've probably replaced a hundred of these things. It's the kind of job where you feel genuinely accomplished afterward.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Normal usage and carbon exhaustion75%
High sediment levels in local water supply15%
Faulty installation or unseated filter10%
Symptoms You May Notice
Your dispenser is barely dribbling instead of flowing normally, and filling a glass takes way longer than it used to, like embarrassingly long.
Ice cubes are coming out small, hollow, or misshapen because the ice maker isn't getting enough water volume to complete a full cycle.
The Replace Filter light on your dispenser panel is red or amber and it won't reset no matter what you press.
Water has a chlorine taste or metallic edge to it. That means the carbon is spent and it's not filtering anything anymore.
Little black specks floating in your water glass. That's carbon fines from the filter media breaking down, and it means the filter is absolutely done.
Can you reset a Frigidaire refrigerator to clear the PUREPOUR-PW-1 code?
Find the 'Water Filter' or 'Reset Filter' button on your exterior dispenser panel. Hold it down for a full three seconds. Don't just tap it, you need to hold it. The indicator light will blink once or twice and then switch to green or show 'Good' on the display. If nothing happens after three seconds, try holding it for five. Some early FRSS26L3AF control boards need a slightly longer press to register.

Frequently Asked Questions
Does the Frigidaire FRSS26L3AF require a specific filter?
Yes, this model takes the PurePour PW-1, which Frigidaire sells under part number FPPWFU01. It's a push-to-lock style, no twisting required. You'll find the housing in the top right corner of your fridge compartment. Don't try to put a twist-lock filter from a different Frigidaire model in there, it won't fit and you could crack the housing trying to force it. The FPPWFU01 is available online and at most appliance parts stores. Prices run about $20 for aftermarket versions up to around $45 for the genuine Frigidaire OEM filter.
Can I use an aftermarket filter instead of the Frigidaire brand?
Honestly, you can, but I've seen aftermarket filters cause more headaches than they're worth. The cheap ones often have O-rings that are just slightly the wrong size, and you end up with a slow drip from the housing even after a fresh install. Some of them also make the inlet valve hum loudly because the flow restriction doesn't match what the valve expects. If your fridge is under warranty, stick with the OEM filter, period. If it's out of warranty and you want to save fifteen bucks, just make sure whatever aftermarket filter you buy is NSF 42 and NSF 53 certified, and check the reviews specifically for fit problems on this model.
Why is my water dispenser still slow after changing the filter?
If you swapped the filter and the flow is still weak, something else is going on. First, make sure the new filter actually clicked in fully, an unclicked filter can restrict flow almost as bad as a clogged one. After that, check your home's water pressure at the fridge line, you need at least 30 PSI for the dispenser to work right. Also look at the braided supply line behind the fridge, those kink easily if someone pushed the fridge back against the wall too hard. If pressure is fine and everything looks good back there, your water inlet valve is probably failing and that's a separate repair.
Do I need to turn off the water supply before changing the filter?
Nope. The filter housing on this model has a built-in shutoff that closes automatically the second you remove the filter. It's honestly one of the things Frigidaire did right here. You'll get maybe a tiny splash when the filter pops out, that's just the few drops left trapped in the housing itself, not a live water line spraying you. Just have a towel ready and you're set. I've changed hundreds of these push-lock filters without ever touching the supply valve behind the fridge.
How do I reset the filter light on the FRSS26L3AF?
Find the Water Filter button on your exterior dispenser panel, it's usually labeled pretty clearly right on the control panel. Press and hold it for exactly three seconds. You should see the indicator light flash or blink, then it'll turn green or display 'Good'. If the light doesn't respond, try holding it a full five seconds. Some earlier versions of the FRSS26L3AF control board needed a longer hold to register. If it still won't reset after that, try unplugging the fridge for 60 seconds, plug it back in, and then attempt the reset again. That clears any stuck display states.
How often should I actually replace this filter?
Every six months is the standard recommendation, and I'd say that's about right for most households. But if you've got hard water, lots of sediment in your area, or you're running the dispenser constantly, you might need to swap it closer to every four months. Don't wait for the light if your water tastes off or the flow slows down noticeably. The light is just a timer, it doesn't actually measure how clogged the filter is. Your flow rate and water taste are better indicators than any light on the panel.
