Pacific Palisades · freezers
Ice on the freezer floor, water on yours
First it is a glassy patch under the bottom basket. Then a thin stream of water appears at the toe-kick, and on a wood floor that is the part that worries people most. In a Sub-Zero freezer, those two clues together usually point to one place: the drain that carries away the water melted during each defrost. When that path freezes or clogs, the water goes wherever it can.

Where defrost water is supposed to go
A Sub-Zero freezer periodically warms its cooling coil just enough to melt the frost that collects on it. That meltwater runs into a trough and down a drain, then out to a pan near the compressor, where warm air evaporates it. You never see it when everything works.
Problems start when the drain cannot do its job. Food particles, a bit of debris or ice can block it. Then the water backs up and refreezes on the freezer floor, building a smooth sheet over time. Sometimes it overflows the trough and finds its way out under the door or through the toe-kick. If the pan itself is cracked or mispositioned, water can also reach the floor from behind the grille.
Other faults can produce similar puddles: a door that does not seal and lets in moisture, an ice maker overfilling, or a supply line weeping. The pattern of ice and water is what separates them.
Why is there a sheet of ice on the bottom of my Sub-Zero freezer?
Most often the defrost drain is blocked or frozen. Water melted during defrost cannot leave, so it collects on the floor of the freezer and refreezes. A door that does not seal fully can add to it by letting moist air in. A technician clears and checks the drain path and the defrost parts.
Ice and water, read together
Where the water appears tells a lot about where it started.
- Smooth, clear ice spreading across the freezer floor
- Likely cause Defrost meltwater that cannot reach the drain
- Water at the front of the toe-kick after the freezer has been opened a lot
- Likely cause Meltwater overflowing the trough, or a door seal letting moisture in
- Water coming from behind the lower grille
- Likely cause A pan that is cracked or out of place, or a supply line leak Read the guide
- Frost thick on the back wall plus ice on the floor
- Likely cause A defrost component that is not warming the coil enough, so ice builds and melts unevenly Read the guide
- Ice clumped around the ice maker with water below
- Likely cause An ice maker problem rather than the drain; see our Palisades ice maker page
Why Palisades homes notice it quickly
General context about houses here, not a record of jobs.
-
Wood floors and open kitchens
Many homes on the bluffs and in the Village area have wood floors running through open kitchens. A small leak is visible and costly, so owners tend to spot it early.
-
Damp marine air
Moist air entering at each opening adds frost to the coil, which means more meltwater for the drain to carry. A partly blocked drain shows up sooner.
-
Houses that sat closed
Where a home stood empty for a stretch, residue in a drain can dry and harden. Once the freezer runs again, the first defrosts reveal the blockage.
-
Garage and pantry freezers
Extra freezer columns and drawers in pantries or garages are opened less, so ice can build for a long time before anyone looks.
What to note before the call
-
Photograph the ice
Where it sits, how thick it is, and whether it is smooth or lumpy.
-
Trace the water
Front of the toe-kick, behind the grille, or under the neighboring cabinet.
-
Check the door
Close it on a sheet of paper along the gasket and feel for spots with no grip.
-
Read the display
Note the setting and the reading, and any message on the panel.
-
Leave the ice in place
Do not chip it out with a knife or screwdriver. Melting it with a hair dryer near water and wiring is not safe either.
Can a clogged defrost drain damage my floor?
Yes, if water escapes under the door or out of the toe-kick and sits on the floor. Wood and the joints between boards are especially vulnerable. Wipe it up, keep it dry, and have the drain cleared before the next defrost cycles send more water the same way.
Palisades freezer questions
- Can I pour hot water down the drain myself?
- Please do not. The drain path is hard to reach without removing panels, and hot water near wiring is a risk. Let the technician clear it safely.
- Will clearing the drain be enough?
- Sometimes. If a defrost part is weak or the door seal is leaking moisture, the drain may block again. The technician checks those at the same visit.
- How is the visit priced?
- Our $89 covers the drive and the diagnosis, a single charge however many cabinets we open, and it is deducted if you go ahead with the repair. The repair figure comes once the cause is clear; see pricing.
- Where can I read more about Sub-Zero freezers in general?
- Our main Sub-Zero freezer repair page covers warm freezers, alarms and frost.
