The short answer
Water at an apartment-size refrigerator usually comes down to one thing: the condensate pan is cracked, overfull or out of position. Next on the list: warm air leaking past the door is condensing and running. 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.
- Water appears at the back rather than inside — A pan fault puts water outside the cabinet, not under a drawer.
- Droplets run down the inside of the door — Room air is condensing on a cold surface, which is not a leak.
- Water pools under the crisper drawers first — The channel backs up before it overflows to the floor.
- 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 condensate pan is cracked, overfull or out of position — First here, because everything the cabinet drains ends up in one shallow pan that is supposed to evaporate it. Knock that pan out of line while cleaning behind the machine, or crack it on a move, and water lands on the floor with nothing wrong upstream at all.
- 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 defrost drain is blocked — Ranked here because it accounts for most refrigerator leaks and it is the only one an owner can fully clear.
- The cabinet is tilted the wrong way for its drain — Last, and free — a spirit level settles it in minutes.
Check in this order, and why
- Isolate the cabinet and check the pan sits square and whole — Everything that drains lands here, so it is always worth a look.
- Paper-test the seal and look for water on the inside of the door — Water on the door rather than the floor means condensation.
- Find the drain hole at the base of the rear wall and clear it — A blocked channel is the commonest leak in refrigeration.
- 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.
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
- Isolate the cabinet, slide the pan out and check it for cracks — Seat it square on its rails when you put it back.
Tools: torchAbout 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.

- Flush the drain hole at the base of the freezer rear wall — Warm water and a soft turkey baster. Never wire.
Tools: warm water, basterAbout 30 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. Leave the freezer door switch wired as you found it: it cuts the evaporator fan for a reason, and defeating it puts a spinning blade behind an open door.
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, it is the more specific answer and you should start there. Deliberately absent: fan and defrost identifiers, wiring colours and capacity figures, which differ between the top-freezer and all-refrigerator families.
