The short answer
A Comptree compact refrigerator that is leaking water is most often a door seal letting humid air in, with a blocked defrost drain close behind. Comptree cubes are sold for offices and dorm rooms, so they spend their lives being opened a dozen times an hour and shut again on a bag or a bottle. 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 puddle on the floor beneath the cabinet — The drip tray is overflowing, shifted or dry and cracked.
- 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 door seal letting humid air in — First on this cabinet: 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 blocked defrost drain — Second, and close behind: 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 drip tray out of place or overflowing — Third: 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 — Last, and that is the whole point of the order: 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
- 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.
- 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.
- Look underneath for the drip tray — Out of place, cracked or overflowing explains a floor puddle immediately.
What an owner can safely check
- 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
- 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
- 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 before flushing the drain or reaching underneath it, because a capacitor can hold a charge after the power is off and you will otherwise be handling water beside a live appliance. Never push a stiff or sharp probe into the drain: the evaporator tubing runs directly behind that wall and a puncture ends the cabinet.
When to call a technician
Call when the drain runs clear, the tray is seated, the cabinet is level and the seal drags on paper, and water still appears. Call at once if the fluid is oily or smells sharp rather than of nothing, because that is not defrost water and the cabinet should be switched off until it has been looked at.

What this page does not cover
This page covers compact single-door refrigerators as a class rather than one model line. Drain positions, tray shapes and liner channels differ between families, and where a family- or model-specific page exists for your unit it is linked below and is the better answer. Deliberately absent here: part identifiers, drain dimensions and anything requiring the plate inside your own cabinet.
