Frigidaire ULTRAWF PureSource Ultra Filter Replacement Guide

Protect the distinction between Ultra and Ultra II

Use the Frigidaire refrigerator guide library to keep this exact replacement connected to the correct model and follow-up troubleshooting.

ULTRAWF is the part identifier for PureSource Ultra. Frigidaire lists it as a push-to-lock filter with a 200-gallon rated capacity. PureSource Ultra II is EPTWFU01, a separate family. The Roman numeral is not decorative packaging language.

Begin with the Frigidaire model-number guide, then verify fit through the Frigidaire water-filter selector. Use the complete model and the appliance manual. HomeMemory’s verified exact-family Amazon ASIN for ULTRAWF is B002JAKRAM.

If the official result returns EPTWFU01, follow the PureSource Ultra II replacement guide. If it returns a PurePour family, compare the dedicated PWF-1 guide or PWF-2 documentation instead. Never select ULTRAWF because “Ultra” appears somewhere in a marketplace title.

Read capacity as a limit, not a promise

Frigidaire’s current official ULTRAWF support listing gives a 200-gallon rated capacity. That specification does not mean every household should wait until an estimated two hundred gallons has passed. Frigidaire’s general guidance says filters should typically be changed about every six months, and actual attention can arrive sooner because of use, flow, taste, odor, a status prompt, or prolonged appliance non-use.

Record both time and observable performance. A household that dispenses little water still needs maintenance timing; a large household can load a cartridge sooner. The refrigerator manual and live manufacturer documentation remain the controlling sources.

Do not use capacity to justify continuing with an active leak, damaged filter, or obvious water-quality change. Those conditions require prompt evaluation.

Inspect the work area before removal

Open the exact model manual and identify the ULTRAWF compartment, any bin that must move, and the proper release motion. Clear nearby food. Place an absorbent towel below the housing solely for residual drops and keep a stable pitcher ready at the dispenser.

Observe the installed cartridge before touching it. Is it square in the receiver? Is the compartment dry? Does the label actually say ULTRAWF? Photograph those details and note current dispenser flow. A before-state turns later troubleshooting into comparison rather than memory.

If moisture is already present, dry it once and see whether it reforms. An existing leak should be resolved before a routine replacement proceeds. Do not reset the display in advance.

Remove the old PureSource Ultra cartridge

Support the filter and use the model’s documented release action. Frigidaire identifies ULTRAWF installation as push to lock, but the appliance manual provides the exact owner procedure and orientation. Maintain alignment while withdrawing the cartridge.

Catch incidental water. If water continues, protect the compartment and shut off the dedicated supply when safe. Do not use pliers, a strap wrench, or a screwdriver on the cartridge or receiver. A plastic water-system mount can be damaged by leverage long before the cartridge moves.

When normal hand force does not release it, pause. Recheck whether the filter must be pushed before withdrawal and whether a cover or latch has a documented position. Mineral residue or a damaged receiver may require service.

Inspect the removed connection. Keep seals where the manufacturer placed them and never transfer a ring from the old cartridge to the new one. Photograph a broken end or deformed component before disposing of anything.

Install ULTRAWF without improvisation

Compare the sealed replacement with the old label and the official fit result. Open it only at the refrigerator. Remove the documented protective cover and keep the connection end clean.

Align ULTRAWF with the filter head and press it through the specified path until the push-lock mechanism retains it. The installed cartridge should remain secure without continued pressure. Do not modify fins, sand plastic, double up seals, or add lubricant.

If it will not lock, do not assume the new cartridge is merely “tight.” Recheck the full refrigerator model, exact ULTRAWF printing, orientation, packaging damage, and accessible receiver condition. A product from another PureSource generation can appear related while remaining wrong.

Reinstall any ordinary bin or cover and dry the area. Do not stack food against the filter in a way that hides leaks or applies side pressure.

Purge air and startup water

Frigidaire’s official prime-and-purge guide explains why this step matters. A newly opened water path can hold air, producing uneven flow, two or three empty ice cycles, and first ice with discoloration or odd flavor.

Hold a pitcher against the dispenser paddle until water starts. Frigidaire says this may take one to two minutes. Continue dispensing for several minutes, discard the water, and repeat. For installation of a new filter, discard three to five tall drinking glasses.

The same support page gives a larger one-gallon minimum for a newly installed refrigerator. That is a different event. Follow the exact model manual if it specifies more detailed purging.

Pause to inspect the ULTRAWF receiver. Sputtering should diminish. A leak, cartridge movement, or moisture that reforms calls for stopping, not dispensing another pitcher.

Discard early startup ice and allow the bin to receive fresh cycles. A filter change affects both dispenser and ice water even when only the dispenser is used for purging.

Confirm the replacement solved the intended problem

For routine maintenance, success means normal stable flow and a dry filter compartment. When declining flow triggered replacement, compare the result with the recorded before state. A clear improvement supports the old filter as a restriction. No change means supply valve position, line condition, household pressure, freezing, or another refrigerator component deserves attention.

If water tastes unusual immediately, first confirm that the complete purge was performed and startup ice discarded. If taste or odor persists, investigate the household water and appliance rather than installing filter after filter.

For a leak, shut down dispensing and protect surrounding surfaces. Verify exact family and seating. A cracked housing or damaged receiver needs qualified repair; tape and sealant are not suitable for a pressurized potable-water connection.

Understand the ULTRAWF bypass path

Frigidaire sells a water-filter bypass documented for PureSource Ultra ULTRAWF and related specified systems. A bypass is intended for certain homes with whole-house filtration. It is not a universal blank, a repair plug, or proof that filtered water is unnecessary.

Use only the bypass confirmed for the exact refrigerator and follow the manual. Store its identity separately from replacement cartridges. If used for diagnosis, document the result and restore the approved configuration.

Reset, record, and plan

Once ULTRAWF is secure, purged, and dry, follow the exact refrigerator control instructions to reset filter status. Displays vary by model. The indicator measures a maintenance interval; it does not inspect seals, identify the cartridge, or verify flow.

Save ULTRAWF, PureSource Ultra, ASIN B002JAKRAM, the refrigerator model, installation date, purge result, and leak check. Schedule a reminder ahead of the expected change point so there is time to reverify fit and purchase safely.

Store any spare sealed in its original package in a clean, dry place protected from damage and extremes. If the appliance changes, do not assume the stored ULTRAWF belongs in the new refrigerator.

Final Verdict

ULTRAWF replacement depends on one small but critical naming check: PureSource Ultra is not Ultra II. Confirm the complete model, preserve the push-lock housing, purge startup air and water, and verify the compartment stays dry. Save the exact ULTRAWF identity and installation date so the next maintenance event does not begin with another compatibility guess.
