Protect floors and power: wipe up water, keep it away from outlets and the toe-kick area, and close the water supply valve to the refrigerator if water keeps coming.
Short answer
Where Sub-Zero leaks usually come from
Water inside the fresh-food section or under the crisper drawers usually means a clogged or frozen defrost drain: meltwater from the defrost cycle cannot reach the drain pan, so it overflows inside the cabinet. Ice on the floor of the freezer points the same way.
Water on the floor in front of the unit is more often the water side: the ice maker fill line, the water valve, a loose or cracked water filter housing, or a supply-line connection behind the unit. Condensation on the liner can also come from a door that is not sealing. Alpha Pro finds the source the same day for a $99 service call, credited to the repair.
Owner-safe checks
Checks you can make before calling
Check the water filter
Make sure the filter is seated and locked. A filter replaced recently and not fully turned is a classic front leak.
Look for ice
A sheet of ice under the drawers or in the freezer floor usually means a frozen defrost drain.
Check door seals
Run a hand along each gasket; condensation streaks on the liner suggest warm, humid air getting in.
Shut off the supply if needed
If water keeps reaching the floor, close the supply valve and turn the ice maker off until diagnosis.
Common causes
Most likely reasons, in the order we check
- Clogged or frozen defrost drain: meltwater overflows inside the refrigerator or freezer
- Water filter housing: an unseated filter or cracked housing leaks at the front
- Ice maker fill or water valve: a leaking valve or fill tube drips behind or under the unit
- Supply line connection: a loose or aged line behind the built-in
- Drain pan: a misplaced or cracked pan lets defrost water reach the floor
- Door seal: humid air condenses and runs down the liner
Appointment preparation
Information that speeds diagnosis
- Model and serial number.
- Where the water appears and how often.
- Whether the filter or water line was changed recently.
- Any ice buildup inside the cabinet.
- Photos of the leak area.
Stop troubleshooting
Call a technician instead of continuing when:
- Water reaches outlets or electrical components.
- Water keeps coming after the supply valve is closed.
- Flooring or cabinetry is getting wet repeatedly.
- The unit also stopped cooling.

Why is there water under the crisper drawers?
Most often the defrost drain is clogged or frozen, so defrost water collects inside the cabinet instead of reaching the drain pan.
Can a water filter cause a leak?
Yes. A filter that is not fully seated, or a cracked filter housing, is one of the most common front leaks.
Is a leaking Sub-Zero dangerous?
Water near the toe-kick can reach electrical parts and damage floors and cabinetry. Dry the area and shut off the water supply until it is repaired.
