The short answer
Water at a compact refrigerator usually comes down to one thing: the cabinet is tilted the wrong way for its drain. Next on the list: defrost melt water overrunning the small tray. Where the water appears — under a drawer, behind the cabinet, or down the door — decides this faster than any tool.
What you observe
- Water where there was none before — Under a drawer, behind the cabinet, or down the door — each points elsewhere.
- The leak started after the cabinet was moved or cleaned behind — Nothing failed; the geometry the drain relies on changed.
- A large puddle the day the cabinet was defrosted — Timing alone identifies this one.
- Droplets run down the inside of the door — Room air is condensing on a cold surface, which is not a leak.
- NEAR MISS — the cabinet is also failing to hold temperature — Read the cooling page first — that is one fault with two symptoms.
Causes, most likely first on this unit
- The cabinet is tilted the wrong way for its drain — First on this unit because it stands in a garage, a basement or a workshop and has been moved. The internal channel relies on gravity and a very small fall; tip the cabinet forward or sideways and the water runs to a corner with no drain in it instead of to the one that has.
- Defrost melt water overrunning the small tray — Ranked here because it happens every single defrost unless the tray is emptied part-way through.
- Warm air leaking past the door is condensing and running — Ranked here because a seal fault leaks water as readily as it leaks cold, and only one of those is obvious.
- The condensate pan is cracked, overfull or out of position — Last, and worth a look while the coil is being cleaned anyway.
Check in this order, and why
- Put a level on the cabinet top, front to back and side to side — The drain relies on a small fall; tilt the wrong way and it fails.
- Note whether the water appeared during or just after a defrost — The tray on this class cannot hold a whole defrost in one go.
- Paper-test the seal and look for water on the inside of the door — Water on the door rather than the floor means condensation.
- Isolate the cabinet and check the pan sits square and whole — Everything that drains lands here, so it is always worth a look.
What an owner can safely check
- Dry everything and find out where the water reappears first — The first wet point is the source; mopping blind loses the diagnosis.
Tools: towelsAbout 15 min
- Level the cabinet with the front very slightly high — Recheck after a day of normal use.
Tools: spirit levelAbout 20 min
- Empty the drip tray part-way through any defrost — Lay towels at the front before you start.
Tools: towelsAbout 20 min
- Paper-test the seal all round and clean the gasket channel — Anywhere the paper slides free is where the air is getting in.
Tools: paper, clothAbout 15 min
- STOP HERE before disturbing any water fitting or removing a rear panel — Water under pressure and live terminals in the same space is a service job.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never chip ice off the cold plate. The refrigerant tubing runs inside that plate and a puncture scraps the cabinet outright — let it melt instead.
When to call a technician
Call once you have cleared the drain, confirmed the cabinet is level and dried the area, and water still returns. Call without waiting if water behind the cabinet refills after mopping: pressurised water does not stop on its own. Call immediately if water is reaching an outlet, a plug or any electrical connection — switch the circuit off first.

What this page does not cover
This page is written for the brand and the cabinet class, not for one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer. Deliberately absent: thermostat and relay identifiers, wiring colours and capacity figures, which differ between the cube, tall compact and glass-door families.
