Frigidaire ULTRAWF Water Filter: Complete Replacement Guide + Best Compatible (2025)
The Frigidaire ULTRAWF — also known as the PureSource Ultra II — is the primary water filter for Frigidaire and Electrolux French door and side-by-side refrigerators manufactured from approximately 2013 onwards. It uses a push-button release mechanism and mounts inside the upper right of the refrigerator compartment.
Also known as: PureSource Ultra II, WF3CB (older cross-ref), 242046801 | Type: Push-button internal | Location: Upper right fridge interior | Life: 6 months / 200 gallons | NSF: 42 and 53 | Compatible price: $18.95
Frigidaire makes two commonly confused filters. The ULTRAWF (PureSource Ultra II) is used in French door and larger side-by-side models. The PAULTRA (PureSource Ultra) is a smaller filter used in specific Frigidaire and Electrolux bottom-freezer models. They are NOT interchangeable. Check your installed filter label to confirm which model you need. PAULTRA guide: Frigidaire PAULTRA Complete Guide.

How to Install the Frigidaire ULTRAWF — Step by Step
Locate the Filter Housing
Open the Frigidaire fridge. Look in the upper right interior corner of the refrigerator compartment for a cylindrical housing with a push-button release visible on the face.
Turn Off Ice Maker and Press Eject Button
Switch off the ice maker. Then press the eject button on the filter housing — the filter will partially pop out. Pull the filter straight out the rest of the way. Have a towel ready for a small drip.
Remove the Protective Cap
Unpack the new ULTRAWF. Remove the plastic protective cap from the O-ring end. This is the most common installation mistake on Frigidaire filters — the cap looks like part of the filter body but must be removed before insertion.
Insert Until It Clicks
Align the filter with the housing, ensuring the notch is matched. Push firmly and straight in until you hear and feel a firm click. The eject button will pop back to flush. No wobble when correctly seated.
Flush 2–3 Gallons
Run the dispenser for 4–6 minutes, discarding the output. Continue until water is completely clear. Turn the ice maker back on. Full guide: How to Flush a New Refrigerator Water Filter.
Reset the Filter Light
Press and hold the Reset or Filter Reset button on the Frigidaire control panel for 3 seconds. The “Replace Filter” indicator should turn off or change to green. Full guide: How to Reset the Filter Light.
🔴 “The Red Light Won’t Reset” — Frigidaire-Specific Fix Guide
Frigidaire refrigerators — particularly models from 2010 to 2017 — have a well-documented quirk where the filter indicator stays red even after a correct button press. Here is the complete fix sequence by model series:
| Frigidaire Reset Method | Applies To | Duration |
|---|---|---|
| Hold “Filter Reset” button | FGHB, FGHN, FGHD (2015+) | 3 full seconds |
| Hold “Reset” on dispenser panel | Older FFHN, FFHB models | 3 seconds — listen for beep |
| Hold “Options” + “Ice Off” together | Select 2010–2014 Gallery models | 3 seconds until filter icon disappears |
| Hold “Water” + “Ice” together | Some older Frigidaire side-by-side | 3–5 seconds until panel blanks |
| Power cycle (unplug 60 seconds) | All models — last resort | Unplug 60s → replug → reset immediately |
The #1 reason the Frigidaire reset fails: the button is released too early. The control board requires a continuous uninterrupted 3-second hold. Many users release at the first click or LED flash — before the reset registers. Use a phone timer. Hold for 3 full seconds. If the light remains red after 5 correct attempts, the power cycle method (unplug 60 seconds) clears the board for a fresh reset attempt.
