The short answer
Water around a plumbed rental-duty refrigerator should be traced to either the supply line or the defrost drain, and the supply line is checked first because it is the one that damages the building. A blocked defrost drain is the more common cause, and it shows as water under the crisper or ice on the freezer floor.
What you observe
- Water pooling under the crisper drawers — Meltwater backing up because the defrost drain is blocked.
- A sheet of ice on the freezer floor — The drain has frozen and the water freezes where it stands.
- A wet patch behind or beside the cabinet — Suspect the supply line, and close its valve now.
- NEAR MISS — water with soft food — Then the cabinet has a cooling fault and the water is the melted evidence.
Causes, most likely first on this brand
- A blocked or frozen defrost drain — First in frequency: the drain is a small hole at the base of the evaporator area, and food debris and ice both stop it. Meltwater then runs forward into the cabinet.
- A weeping supply fitting or crushed line — Second in frequency, first in consequence, and far more likely in a rental because the cabinet is moved often. It runs whether or not the appliance is doing anything.
- A displaced or cracked drain pan — Third: the pan sits under the cabinet above the compressor and gets knocked every time the machine is moved. Floor water rather than cabinet water is its signature.
- Tired door gaskets — Fourth, always contributing: more humid air in means more frost and more meltwater than the drain was sized to carry away.
Check in this order, and why
- Decide whether the water is inside the cabinet or behind it — Behind it means the supply line and it changes the urgency.
- If the cabinet is plumbed, close the supply valve first — Stop the damage before you diagnose anything.
- Look for ice on the freezer floor — It is the clearest sign of a blocked or frozen defrost drain.
- Check the drain pan underneath last — It explains floor water rather than cabinet water.
What an owner can safely check
- Close the water supply valve if water is behind the cabinet — This is the step that protects the floor and the apartment below.
Tools: torchAbout 10 min
- Empty the lower shelf and dry the cabinet floor — You need a clear view of the drain at the back.
Tools: clothAbout 15 min
- Flush the drain with warm water and a soft wire — Work gently and never force a stiff or sharp tool into it.
Tools: warm water, soft wireAbout 25 min
- Defrost fully if the drain is frozen solid — A frozen drain will not clear while the cabinet is cold.
Tools: towels, coolerAbout 90 min
- Pull the cabinet out and re-seat the drain pan — The hose should discharge over the pan and the pan sit square.

Before you open anything
Safety
Unplug the refrigerator before flushing the drain or reaching behind it — 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 sharp probe into the drain, because evaporator tubing runs behind that wall. Dry the floor as you work and treat moving a loaded cabinet as a two-person job.
When to call a technician
Call, or report it immediately, if water is coming from the supply line or has reached the floor structure, because in an apartment that becomes somebody else's problem quickly. Call a technician when the drain runs clear, the pan is seated, the gaskets seal, and water still appears. Oily fluid rather than clear water means the sealed system and the cabinet should be switched off.
