Ice maker & water line
Sub-Zero ice maker & water line repair
A Sub-Zero ice maker that’s stopped or struggling usually traces to a clogged or frozen fill tube, a failed water inlet valve, a worn ice module, a kinked or leaking water line, or a freezer running too warm. We diagnose the whole path — supply, valve, fill and freeze — fix the leak at its source, and install genuine OEM parts. The $89 service call is waived when you book the repair, with a 365-day labor warranty on the work.

Quick answers
Quick answers
Why did my Sub-Zero ice maker stop?
Most often a failed inlet valve, a frozen fill tube, a worn module, or a freezer that’s running too warm. We test the full water path to find the actual cause.
There’s water leaking — is it urgent?
Treat active leaks as urgent, especially upstairs or over finished floors. We hold slots for leaks and trace them to the source rather than just mopping up.
How fast can you fix it?
Common valve, fill-tube and module repairs are often same-visit once diagnosed. We confirm the part with your model and serial.
Why a Sub-Zero ice maker stops
Ice production is a small system with several failure points. A water inlet valve that won’t open starves the maker; a fill tube that freezes blocks water before it arrives; a worn ice module won’t cycle or eject; and a freezer running warm simply can’t freeze fast enough. Leaks usually come from the supply connection, the valve, or a cracked line behind the unit.
Because the symptom — "no ice" — has so many possible causes, we test the full path rather than swapping the module and hoping.
Symptom guide
Ice & water symptoms → likely cause → what we do
| Symptom | Likely cause | What we do |
|---|---|---|
| No ice at all | Inlet valve, fill tube or module | Test water supply, valve and module cycle |
| Low or slow production | Freezer temp or partial restriction | Check freezer temp and water flow |
| Water leaking under unit | Supply line, valve or drain | Trace the leak to its source and repair |
| Hollow or small cubes | Low fill / partial valve | Verify fill volume and valve operation |
| Clumping or off-taste | Old filter / low turnover | Replace filter; advise on turnover |
We test the whole water path before replacing parts.
Quick checks
What to check before you call
- 01
Confirm the supply
Make sure the household water supply and the unit’s shut-off valve are fully open.
- 02
Check the freezer temp
A freezer that has warmed up can’t make ice quickly — confirm it’s holding temperature.
- 03
Look for a leak
Glance behind and under the unit for any moisture so we can trace it on arrival.
- 04
Note the pattern
No ice at all, slow output, or leaking — tell us which, and your model/serial if handy.
Leaks: find the source, not just the puddle
Water under or behind a built-in is worth taking seriously, especially in upstairs condos near Castro Street or over finished floors in estate kitchens. We trace a leak to its origin — supply line, inlet valve, fill tube or a blocked defrost drain — and repair it properly, then check that nothing downstream was damaged.
Clean ice, OEM parts
Off-taste or cloudy, clumping ice often points to an old filter, a slow fill or stale cubes from low turnover. We address the cause and use genuine OEM Sub-Zero parts so the repair lasts — all backed by a 365-day labor warranty.
Before we arrive
Safe checks you can do
- Verify the water supply line and shut-off valve are open.
- Replace the water filter if it’s overdue (a common, easy cause).
- Make sure the ice maker isn’t switched off or in a paused mode.
- Clear out old, clumped ice so we can see fresh production.
Reviews
What Mountain View homeowners say
No ice for a week. They found a failed inlet valve and a partly frozen fill tube, fixed both with OEM parts the same visit, and the $89 came off the bill. Ice within hours and a year of warranty.
Small leak under the built-in in our condo. They traced it to the supply connection rather than guessing, fixed it, and checked the floor. Careful, fast, and reassuring given we’re upstairs.
Cubes were small and clumping. Turned out to be an overdue filter plus a lazy valve. Honest fix, no upsell, and clear advice on turnover. Great service.
FAQ
Frequently asked questions
My Sub-Zero ice maker isn’t working — what’s the most common cause?
The most common causes are a failed water inlet valve, a frozen or clogged fill tube, a worn ice module, or a freezer running too warm to freeze quickly. We test the supply, valve, fill and freeze cycle to find the real fault before replacing anything.
Water is pooling under the unit — can you help?
Yes, and we recommend booking promptly. Leaks usually come from the supply connection, inlet valve, fill tube or a blocked defrost drain. We trace it to the source and repair it, then check for downstream damage.
Why is my ice cloudy, small, or clumping?
Small or hollow cubes often mean a low fill or a partial valve; clumping and off-taste usually point to an old filter or low turnover. We correct the fill and water quality at the cause.
Do I need to replace the whole ice maker?
Rarely. Most ice problems are a single component — valve, fill tube or module — not the entire assembly. We replace only what’s failed, with genuine OEM parts.
How much does ice maker repair cost?
Most ice and water-line repairs fall in the $275–$850 range depending on the part. You get an itemized quote on-site and the $89 service call is waived with the repair.
Do you cover nearby cities?
Yes — Mountain View plus Los Altos, Palo Alto, Sunnyvale and Los Altos Hills. See our service-areas page for coverage.
