Westwood · ice maker
The filter went in. The ice stopped.
It is a familiar puzzle in condos and houses around the village: someone swaps the water filter, does everything the reminder asked, and the bin never fills again. Usually the culprit is small and sits right at the cartridge. Sometimes the change just happened to coincide with a real fault. Below is how to sort one from the other before spending money on a visit. The broader picture lives on our Sub-Zero ice maker repair page.

Retrace the filter change in this order
Each step takes a minute or two and needs no tools. Do them in sequence, because the early ones settle the most cases.
-
Pull the cartridge and seat it again
Remove the new filter and reinstall it slowly, turning or pushing until you feel it lock. A cartridge that stops a few degrees short of its stop can look finished while blocking the water path completely. If your model's filter sits behind the top grille, a flashlight helps you see the alignment marks.
-
Compare the part against your manual
Hold the old cartridge next to the new one. Same shape, same locking tabs, same length? Filters from different refrigerator generations can look close and still fail to engage the valve inside the housing. The manual for your unit names the cartridge it needs.
-
Look for a bypass plug or cap left behind
Some installers leave a cap or plug in the housing during a remodel or a long vacancy. If you found one when you opened the housing and did not put it back the way it came out, mention it when you call.
-
Check that the ice maker is still switched on
People often lean on the ice maker arm or switch while reaching for the filter. Make sure the switch, button or arm is in its on position, as described for your model.
-
Give it a day, then discard the first harvests
A fresh cartridge often traps air, so the first cubes come out small, hollow or cloudy, and the first cycles may push out nothing at all. Let the unit run, toss the early batches, and judge it after it has had time to cycle normally.
-
Reset the filter indicator if your model has one
Where there is a filter reminder, the manual explains how to clear it. A reminder that stays lit will not stop ice by itself, but resetting it keeps the next change on track.
Water near the cabinet is the exception
What the bin is telling you
The pattern after the change says a lot. Match what you see, then decide whether to wait, re-check, or book.
- No ice at all, and the dispenser (if you have one) gives no water either
- Likely cause Cartridge short of its stop, the wrong part, or a cap left in the housing; water never gets past the filter
- Small, hollow or crescent-thin cubes for the first day
- Likely cause Air purging from a new cartridge; usually clears on its own once the line is full again
- Thin cubes that never return to normal size
- Likely cause Restricted flow: a filter partly seated, weak supply pressure, or a tired fill valve Repair page
- You hear water trying to fill, but the tray stays dry
- Likely cause A frozen fill tube, often from a slow trickle that froze while the filter was out
- Ice maker clicks and cycles, but the bin stays empty
- Likely cause A harvest problem unrelated to the filter: ejector motor, thermostat or control; the timing with the filter change is coincidence
- Plenty of ice, yet the fresh-food compartment runs warm
- Likely cause Not a filter issue at all; a cooling fault worth a separate look on our Westwood refrigerator page Repair page
Why is there no ice from my Sub-Zero since I put in a new water filter?
Usually because the new cartridge is not fully locked, it is the wrong filter for that model, or air trapped in the new filter is delaying the first fills. Reseat it until it clicks, confirm the part number in your manual, and let the unit cycle. If there is still no ice, the fault is elsewhere.
Filter-day beliefs we hear often
-
Often heard
Any filter that fits in the slot will work.How it really worksFitting into the opening is not the same as engaging the valve. A cartridge for a different generation can slide in and still leave the water path shut.
-
Often heard
If the first cubes are tiny, the new filter is defective.How it really worksAir in a new cartridge is normal. Small or hollow cubes on the first day are expected; it is the cubes a few days later that matter.
-
Often heard
No ice right after the change means the ice maker died at the same moment.How it really worksIt happens, but it is the rarer explanation. Rule out seating and the part number first; a genuine fault persists once the cartridge is cleared of suspicion.
-
Often heard
Skipping the filter entirely will get the ice going again.How it really worksOnly where the manual allows running with a bypass. On some models running without a cartridge or plug leaves the housing open to leaks. Follow the guide for your model.
How can I tell a Sub-Zero water filter is installed properly?
It should turn or push to a firm stop and stay there without spinning back, with any alignment marks lined up as the manual shows. A cartridge that pulls free without effort, or a housing that weeps water, means it never locked. Remove it and install it again slowly.
Wait, check, or call
A quick way to decide what to do next once you have retraced the change.
Ice maker behavior after a filter change
| What you notice | Most likely meaning | Next move |
|---|---|---|
| Small or hollow cubes on day one | Air leaving the new cartridge | Let it cycle; discard early batches |
| No ice, no water anywhere | Filter not locked or wrong part | Reseat it and compare the part with your manual |
| Water at the housing or on the floor | Cracked housing or failed seal | Remove the filter, dry the area, book a visit |
| Fill sound but dry tray | Frozen fill tube or failing valve | Book a visit and leave the frozen tube alone |
| Normal water, still no harvest | Ice maker module or control fault | Book a visit; the filter is not the cause |
| Ice normal, fresh-food side warm | Separate cooling problem | Book a visit and describe both symptoms |
Who repairs Sub-Zero ice makers near UCLA and Westwood Village?

How Westwood living changes an ice maker call
Nothing here is a customer list, just the shape of the neighborhood and why it matters when water and ice are involved.
-
High-rise condos along Wilshire
Tall buildings deliver water through their own pumps and valves, and plumbing work on a riser can briefly change pressure on many floors. If ice slowed around the time your building had water work, tell us; it shifts where we look.
-
Apartments stacked over neighbors
A weeping filter housing is a bigger deal on an upper floor than in a house on a slab. So on the phone we ask about any water you have spotted, not just about the cubes.
-
Single-family streets near the village
Older Westwood houses with remodeled kitchens sometimes have newer refrigerators on older supply lines and shutoffs. A tired shutoff that will not open fully can look exactly like a filter problem.
-
Campus traffic and parking
Around UCLA, parking near the door is not a given. While booking, mention visitor parking, a loading zone or a gate code for the garage, and which floor the kitchen is on.
Ice and filter questions from Westwood kitchens
- When is a Sub-Zero filter due for replacement?
- Go by the interval printed in the manual for your model, and by the reminder light where one exists. Local water and heavy ice use both affect it, which is why the manufacturer's guidance beats any rule of thumb.
- Can a cheaper aftermarket filter stop the ice maker?
- It can if it does not engage the housing the way the listed part does. Some fit loosely, some never open the valve. If the ice stopped right after switching brands, try the filter your manual names before booking.
- The cubes have been small for a week. Is that still air?
- Probably not. Air usually clears within the first day or so of normal cycling. Persistent small cubes point to restricted flow, which might be the filter, the supply pressure, or the fill valve.
- I changed the filter and now there is water under the refrigerator. What do I do?
- Remove the cartridge, dry the floor and watch the spot for a few hours. If water keeps appearing, or you see it coming from the housing itself, book a visit and avoid using the filter until it has been checked.
- Can the technician check my other Sub-Zero units during the same stop?
- Yes. $89 pays for coming to the home rather than for a single appliance, so the wine storage or an undercounter module in the same Westwood home gets a look during that one stop. Every fix is priced on its own, and only the ones you approve get done.
- Can I book for today?
- When the schedule has a gap, yes. Someone picks up 24/7, and technicians are out 8 AM until 6 PM daily. Ring (310) 878-0630 or use the booking page, and note the building, the floor and where to park.
- Where can I read more before I call?
- The article on ice makers that quit walks through failures unrelated to the cartridge. In a house rather than a condo, our Brentwood ice maker page looks at the problem from another angle, and the visit fee is laid out here.
Still no ice after you reseated it?
Give us the day you swapped the cartridge and what the bin has done since. A single $89 trip charge applies to every Sub-Zero appliance in the apartment or house and is deducted from the repair. The neighborhood overview sits on our Westwood page.
Trip charge $89, counted per driveway and never per unit; it is credited in full once you approve the repair.
