The short answer
Water inside the cabinet or on the floor: on an iio refrigerator that is usually a blocked defrost drain, not a cracked evaporator pan behind the panel. Second, and worth checking in the same hour, is humid air condensing past a bad seal. Work the order below -- cheap causes first, the one that is not an owner fix last.
What you are looking at
- Water stands under the crisper drawers — It collects at the lowest point inside the cabinet.
- A puddle appears on the floor at the front — It returns within a day of being mopped.
- There is a sheet of ice on the freezer floor — Melt water froze where it pooled.
- NEAR MISS -- water only after the filter was changed — That is a fitting or housing left loose, not a drain fault.
Causes, most likely first on this kind of unit
- The defrost drain is blocked or frozen — Melt water from each defrost has one route out. Ranked first: on an iio compact cabinet on a simple dial control, it is the single most common source of water in a refrigerator, and clearing it is owner work.
- The door seal is letting humid air in — A leaking gasket admits warm humid air that condenses on the nearest cold surface. Ranked here because condensed room air is water that never came from a pipe, which is why the supply looks fine.
- The cabinet is not level — Drain troughs and pans rely on a level cabinet to carry water to the right place. This rank, because a tilt sends water the wrong way even with a perfectly clear drain.
- The trough or evaporator pan behind the panel — A cracked interior trough, a failed drain heater or a split hose behind the rear panel needs the panel off and the compartment thawed to reach. Last, and that is the point of the order: it needs a panel off and a meter on a heater circuit, which is why it is last.
Check in this order, and why
- Look in the trough and at the drain mouth — Ice or sludge at the drain, with water standing in the trough, is the confirmation.
- Paper-test the gasket and look for sweat — Water or frost at one corner, with a seal that fails the paper test there, is your answer.
- Only after the accessible drain is proven clear — Water returning with a clear drain, a level cabinet and a good seal points behind the panel -- a service call.
What an owner can safely check
- Mop up, then find out where it returns first — Dry inside and out, then check both in an hour; where it reappears names the source.
Tools: towelsAbout 15 min
- Clear the defrost drain from inside — Flush the trough with warm water and clear the drain mouth gently; never force a wire through it.
Tools: warm water, turkey basterAbout 20 min
- Paper-test the door seal and level the cabinet — Fix a failing seal stretch and set the feet so the cabinet sits level front to back.
Tools: levelAbout 20 min
- STOP HERE -- the next step needs the rear panel off — Interior troughs, drain heaters and hoses behind the panel are technician work.
Before you open anything
Safety
Unplug the unit or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off.
When to call a technician
The line is simple: anything you can reach without a panel is yours, anything behind a panel or on the sealed system is a technician's.

What this page does not cover
This page covers the iio refrigerator as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer -- go there first if your model is named. Deliberately not here: drain-trough geometry, heater part numbers, panel-removal order and fitting sizes, all of which differ by family.
