Filter for a Viking Refrigerator: Which Cartridge and When
The filter for a Viking refrigerator is a model-matched water cartridge: RWFDISP for 7 Series integrated units, RWFRVFFR for the RVFFR336 French-door and RWFIC for FDREIC columns. Replace it every 6 to 12 months, flush the dispenser, then reset the reminder.
The filter for a Viking refrigerator is a water cartridge matched to the model: RWFDISP fits 7 Series integrated refrigerators and freezers, RWFRVFFR fits the RVFFR336 French-door, and RWFIC fits FDREIC integrated columns. Plan on a new one every 6 months on that French-door, no later than 12 months on the integrated line, and every nine months or 750 gallons on older built-ins from manual F20413. Swap it, flush the dispenser, then reset the reminder.
Getting the number right matters more on a Viking than on a freestanding fridge. Plenty of Wellesley kitchens tuck a full-height built-in behind cabinet panels, so the label you would normally glance at is out of sight, and a cartridge ordered from a photo of the old one tends to end up in a drawer or, worse, half-seated and dripping.
Read the model plate before you order
Start with the model number rather than the shape of the old cartridge. On 5 Series built-ins the serial and model numbers are printed on the upper wall inside the cabinet, hidden behind the lighting. On FDREIC, FDFZIC and FDBMIC7360 integrated units the product plate is inside the refrigerator section, on the wall across from the side the door opens on.
Take a phone photo of that plate. It lets you check the cartridge number against the use and care manual for that exact model, and it saves a second trip to the store. If the characters are faint, a flashlight held at a low angle usually brings them out.
Which cartridge, where it lives, how often
| Viking line | Cartridge | Change it | After the swap |
|---|---|---|---|
| Older built-ins, manual F20413 (VCSB423, VCBB363) | the one listed in that manual | nine months or 750 gallons, whichever comes first | run the dispenser three minutes |
| RVFFR336 French-door | RWFRVFFR, internal | every 6 months | hold Alarm Off for 3 seconds |
| 7 Series integrated | RWFDISP, bottom right behind the door | per the model’s manual | press the lit FILTER button |
| FDREIC integrated column | RWFIC, internal | 12 months or 3,000 litres (792.6 gal), whichever is sooner | reset; Replace filter returns 12 months later |
The volume limits are what catch people out. A family that fills pitchers, a coffee maker and pasta pots from the door can pass 750 gallons well before nine months are up, and the carbon is spent whether or not a reminder has appeared. If the water starts tasting flat or the stream slows early, believe that over the calendar.
Swapping the cartridge, step by step
- Lay a towel under the housing and keep a small bowl handy; a little water always escapes.
- Release the old cartridge. On 7 Series integrated units, open the door, find it low on the right, and give it a quarter turn counterclockwise. On other lines, follow the housing drawing in your manual.
- Remove any protective cap from the new cartridge, line it up, push it in and turn it back the other way until it stops firmly. One that stops short is the usual source of a slow drip.
- Flush the line by running the dispenser into a pitcher. The F20413 manual asks for three minutes, and that is a sound habit on any model because it pushes out air and loose carbon dust.
- Reset the reminder using the method in the table.
- Dump the next batch or two of ice, since it froze from water that sat still during the swap.
A brand-new installation is its own case. On 5 Series built-ins, allow 24 to 48 hours before expecting ice and discard the first three full drawers; after the house has stood empty for a long stretch, throw out the first drawer it makes.
What a tired or wrong filter does to ice, water and the fridge
A clogged cartridge rarely fails all at once. The dispenser thins to a trickle, a glass takes noticeably longer to fill, and the ice maker turns out small or hollow cubes because its timed fill no longer delivers a full charge of water. Taste drifts toward chlorine or just flatness. A wrong or unseated cartridge behaves differently: the dispenser spits as air passes through, water beads under the housing, or nothing comes out at all.
Water quality sets the pace. Sediment stirred up by old pipes or a hydrant flush loads the carbon faster, and hard water slowly leaves scale on the inlet valve screen and the ice maker’s fill cup. The cartridge is the inexpensive part of that chain; the valve and the ice maker are not, so changing on schedule protects them as much as it improves the glass of water.
Reminders that are not about the filter, and when to call
Integrated Viking units also warn about the condenser, and owners often confuse the two. Every 6 months FDREIC, FDFZIC and FDBMIC7360 units flash CHECK COND., a request to clean the coil behind the grille under the door. Press and hold the power key for roughly 3 seconds until the unit goes dark, give it half an hour, take the grille off, clear the coil with a soft brush and the vacuum, then switch back on and clear the reminder. On 7 Series integrated models a blinking CL in the temperature display asks for the same job and clears when you hold the up and down arrows for 3 seconds. That grille is also what some people take for an air filter, so check your manual before buying one.
If a genuine cartridge is in, the line has been flushed and the flow is still weak, the cause sits upstream or inside the machine: a kinked or frozen supply line, a sticking inlet valve, or pressure outside the 20 to 120 psi range that FDREIC units expect on their 1/4-inch copper line. That is the point to book Viking refrigerator repair. Each visit starts with a flat $95 charge that buys the diagnosis along with the trip, and if you go ahead with the fix, that $95 comes off the bill.

Still asked on the phone
Where is the water filter in a Viking refrigerator?
It depends on the line, so read the model plate first. On 7 Series integrated units the cartridge sits low on the right behind the door and releases with a quarter turn counterclockwise. The RVFFR336 French-door and the FDREIC integrated column use an internal filter inside the cabinet, and the manual for your exact model shows the housing.
How often should a Viking refrigerator filter be changed?
Every 6 months on the RVFFR336 French-door, and at 12 months or 3,000 litres at the latest on FDREIC, FDFZIC and FDBMIC7360 integrated units. Older built-ins covered by manual F20413 want a fresh cartridge every nine months or 750 gallons, whichever arrives first. A household that draws a lot of water from the door reaches the gallon limit before the calendar one.
How do I turn off the filter reminder after a replacement?
Use the reset built into your model's controls: on the RVFFR336 hold Alarm Off for 3 seconds, and on 7 Series integrated models press the lit FILTER button once the new cartridge is seated. FDREIC-type integrated units clear the Replace filter message with their own reset and then count down another 12 months.
Why is my ice small or the dispenser slow right after a filter change?
Trapped air or a cartridge that has not turned fully home is the usual reason. Run water through the dispenser for a few minutes, throw out the first batches of ice, and check that the cartridge reached its stop. If flow stays weak with a genuine cartridge, the supply line, the inlet valve or the water pressure needs a look.
Will a cheaper off-brand cartridge work in a Viking?
It may fit, but a cartridge that seals poorly is a common cause of drips at the housing and weak flow. The part numbers printed in your manual, such as RWFDISP, RWFRVFFR or RWFIC, are what the housing was built around, so match the number rather than the shape of the old one.
