The short answer
Refrigerators make water every day by design. On a Cavin refrigerator the question is always whether this is water that failed to leave or water that should never have arrived. That puts a blocked or frozen defrost drain at the top of the list here and an unusually humid room at the bottom.
How this presents
- Damp along one wall inside the cabinet — Condensation from air leaking past a gasket, which is a door problem showing up as water.
- Water appearing only every day or two — That interval matches the defrost cycle, which points at the drain.
- NEAR MISS — condensation on the outside of the doors — Usually humidity rather than a fault; the inside is what matters.
The causes, ordered
- 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. A glass cellar door carries a soft gasket and a long hinge, and on a tall cabinet the gasket at the top corner is usually the first part to stop touching.
- Humidity beyond what the cabinet can manage — In a humid garage or an unconditioned room, condensation appears on and in a perfectly healthy unit. Cellar cabinets are routinely installed in a dining room or a converted closet, and a cabinet asked to hold cellar temperature in a warm room runs continuously without ever getting there.
- An unusually humid room — Garages and unconditioned rooms put far more water through the evaporator than the drain was designed to carry.
Check in this order, and why
- Establish exactly where the water first appears — Inside, at the front, or behind.
- 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.
- Look for an ice slab under the crisper drawers — It is the classic fingerprint of a blocked defrost drain.
The checks you can do without a meter
- Clear and dry the cabinet, then watch where it returns — A leak with a known starting point is a solved leak. Dry everything, then check at intervals over a day.
Tools: towels, torch
- Empty the crisper drawers and check for ice under them — Remove the drawers, lift the liner and look at the floor of the compartment.
- Flush the drain opening at the rear of the freezer floor with warm water — Use a bulb syringe rather than anything rigid; never push wire into the drain.
Tools: bulb syringe
- 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 this stops being a home repair
Flushing a drain, checking the pan and correcting the level are yours. A drain heater, a trough behind the evaporator or a valve on the supply side is a technician job, and a leak that has reached flooring or electrics is a same-day call rather than a weekend project.

What this page does not cover
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.
