The short answer
A leak is a drainage problem far more often than a supply problem. That puts a blocked or frozen defrost drain at the top of the list here and a drain trough or gutter blocked above the drain hole at the bottom.
What the machine is doing
- Water pooling inside, under the crisper drawers — The classic blocked defrost drain.
- Water at the front edge under the door — Typically an overflowing drain pan path or a door that is not sealing.
- NEAR MISS — condensation on the outside of the doors — Usually humidity rather than a fault; the inside is what matters.
The ranking
- A blocked or frozen defrost drain — The most common leak on any refrigerator. Drainage is where water that the machine made on purpose goes wrong, so it leads whenever water is the complaint.
- A door seal letting humid air in — Warm air meeting cold surfaces condenses. A cabinet that sweats internally is often reporting a gasket fault as a leak. Ranked high because the door is the part built to the lower cost on a sub-line cabinet, so it deserves the check the electronics do not.
- Humidity beyond what the cabinet can manage — In a humid garage or an unconditioned room, condensation appears on and in a perfectly healthy unit. The surroundings are part of the machine: rate it against warmer air and the same hardware behaves like a failing unit.
- An unusually humid room — Garages and unconditioned rooms put far more water through the evaporator than the drain was designed to carry.
- A drain trough or gutter blocked above the drain hole — Water sheets sideways before it reaches the drain and then runs into the cabinet.
Check in this order, and why
- Ask whether a filter was changed recently — A filter head is the most common leak after any maintenance.
- Look at the freezer floor for a flat sheet of ice — It is the frozen version of the same blocked drain.
- Dry the floor and lay paper towel under the front and the rear — Where the paper wets first tells you which end the water comes from.
The owner-side procedure
- Flush the defrost drain from inside the cabinet — Find the drain opening at the back of the cabinet floor and flush it with warm water until it runs freely.
Tools: warm water, turkey baster or syringe
- Thaw a frozen drain rather than forcing it — Empty the freezer, switch the unit off and leave the doors open until the ice is gone.
Tools: towels
- STOP before removing the rear panel to reach the drain trough — A drain heater or a trough behind the evaporator means a panel and live terminals. That is a technician job.

Safety
Dry the floor before plugging anything back in, and keep power leads and extension blocks out of any puddle. Unplug the cabinet before pulling it out over a wet floor; a capacitor can hold a charge after the power is off.
When to stop and call
Flushing the drain is the owner repair. A cracked liner, a failed pan or a supply-line fitting is a technician job, and a water line under pressure is one to shut off first.

Generalized information: this describes the refrigerator class, not your serial number. Anything tied to a chassis — pinouts, part numbers, diagnostic key sequences — is absent by design. A family- or model-level page, where one exists, is linked below and takes precedence. The brand overview page linked below covers the other problems on this machine.
