The short answer
Start with a blocked defrost drain: on a Chill by Hisense frost-free compact refrigerator it accounts for more of these than anything else, and a door seal letting humid air in is the next thing to rule out. This is a Hisense platform with an evaporator behind a rear panel and a fan moving the air, so the cold in the cabinet is made somewhere you cannot see. The checks below are ordered to match, and the first of them needs no tools at all.
What you observe
- Water pooling under the salad drawer — Meltwater that could not reach the drain at the back of the liner.
- A sheet of ice on the freezer floor — The drain closed some time ago and what should have run away froze where it stood.
- NEAR MISS - water with soft food and a thick slab of ice — Then the cabinet has a cooling fault and the water is the evidence rather than the problem.
Causes, most likely first on this brand
- A blocked defrost drain — The likeliest cause on this brand: the drain hole is small, it sits at the lowest point of the cooling surface where crumbs and label paper collect, and once it closes the meltwater has to go somewhere - forward, into the cabinet.
- A door seal letting humid air in — Next most likely: more incoming humidity means more frost, and more frost means more meltwater than the drain was ever asked to carry, so a marginal drain finally overflows.
- A drip tray out of place or overflowing — Third on the list: the tray only rests in clips above the compressor, so it shifts whenever the cabinet is moved and a tray half out of position spills everything the drain sends it.
- A cabinet standing nose-down — Least likely, and the only one that is not your work: these are light enough to be set on carpet, on a shelf or on a floor that slopes, and tilted forward the meltwater never reaches the drain at the back at all.
Check in this order, and why
- Find the drain at the back of the liner and test that it runs — It is the likeliest cause and it clears in minutes, so nothing below it is worth doing first.
- Test the door seal all the way round — It is a contributing cause here rather than a primary one, which is why it comes after the drain.
- Look underneath for the drip tray — Out of place, cracked or overflowing explains a floor puddle immediately.
What an owner can safely check
- Flush the drain gently with warm water — Use warm water and a soft flexible wire only. Never force a sharp tool into the hole.
Tools: warm water, soft wireAbout 20 min
- Close the door on a slip of paper and pull it out at several points — Where it slides out freely, the seal is letting humid air in and making the water you are mopping.
Tools: a sheet of paperAbout 10 min
- Find the drip tray and re-seat it squarely in its clips — It should sit clear of the compressor shell, level, and dry underneath.
Tools: torch, clothAbout 15 min
- STOP HERE if the next step means taking the rear panel off — Behind it are the evaporator and live terminals, and that is where owner checks end.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing the rear freezer panel, flushing the drain or reaching underneath; a capacitor can hold a charge after the power is off. Do not pour hot water or push a rigid tool down the drain, because the tube runs past the evaporator and a drain heater on this design.
When to call a technician
Call when the drain is clear, the tray is in place, the seal drags and water still appears - or when the drain blocks again within weeks, which points at a drain heater rather than at debris. Call at once for oily fluid or a sharp chemical smell.

What this page does not cover
This page covers frost-free compact refrigerators as a class. Drain routing, tray position and drain-heater arrangements differ by family, and where a family- or model-specific page exists for your unit it is linked below and is the better answer. Deliberately not here: part identifiers and any figure that belongs to one model.
