Start here
On these models the defrost drain is the usual culprit and the supply line is the urgent one, so the diagnosis sorts by risk as well as by likelihood. A door seal that has taken a set lets humid air in, which condenses on every cold surface and runs. The drain is owner-clearable on this platform; the supply fitting is not a place to experiment. Part numbers are left to the table above; the text stays with the method, which is what holds.
What owners report
- Water appears only after the icemaker fills — Points at the fill tube, the tray or the connection to it rather than at the defrost side.
- The floor is wet only on one side of the cabinet — Water following a slope rather than pointing at a source. Note where it is dry as well as where it is wet.
- Condensation running down the inside walls — Humid air getting in. Suspect a door seal or a door being held fractionally open by a shelf or a bottle.
- NEAR MISS — the cabinet is also warm — Then the leak is secondary to an airflow problem and the cooling page for this family is where to start.
Causes, most likely first on this roster
- Defrost drain blocked with ice or debris — Top of the list and not close. The drain entry sits at the coldest point in the cabinet, so a slow drain becomes a frozen one, and a season of food debris finishes the job.
- Door seal set, torn or held open — Humid room air meeting cold surfaces. Commoner in summer, commoner still where a bottle or a shelf stops the door travelling the last few millimetres.
- Supply line, fitting or inlet valve leaking — Last by frequency and first by urgency. This is mains water rather than condensate, it does not stop on its own, and it is the one cause on this list that will keep running all week.
The diagnostic order for this family
- Establish whether the water is inside the liner or on the floor — Inside means condensate and the drain; outside at the back means supply. This single observation halves the list.
- Pull the crisper drawers and look at the liner beneath them — Standing water there is the blocked drain, confirmed, and it is the commonest finding on this page.
- Check whether the water appears in step with the icemaker — Water that arrives shortly after a fill belongs to the icemaker path and not to the defrost path.
- Look behind the cabinet at the supply fitting and the tap — Do this early despite it being the least likely: a mains leak is the only one here that gets worse while you think about it.
- Dry everything, then look again after one defrost cycle — Establishes whether the water arrives on a schedule, which separates the drain from everything else.
- Put paper towel under the cabinet overnight — Where it wets first tells you front or back, and that halves the list before any panel comes off.
Isolate first
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Do not run the cabinet with the drain pan removed to see where the water goes.

When to call a technician
Clearing a drain and re-seating a pan are yours. Replacing an inlet valve is not, and on this platform neither is anything requiring the rear liner panel to come off, since it is foamed in place on some of these listings and will not go back the way an owner takes it off.
